DESCRIPTION OF A NEW AND INTERESTING PHASIID-LIKE GENUS OF TACHINIDAE S. STR.
BY C. H. TYLER TOWNSEND, LAS CRUCES, N. MEX. During the last year, I have received,
among several lots of flies from New
Hampshire, a number of specimens of
a tachinid s. str., which I at first inis- took for a phasiid of the genus Hya-
lomyia. Upon examination, recently,
the distinctness of the form was at once realized, but the great resemblance in
almost every detail save one was very
surprising. This one detail will, how-
ever, always be sufficient to distinguish it, and that is the presence of macro-
chaetae on the abdomen, a character
possessed by no phasiid.
From its extreme resemblance to
Hyalomyia, I propose to call the new
genus Hyalomyorles. The species may
be known as H. weed;, in honor of
Dr. Weed, in whose sendings my atten-
tion was first called to this interesting form.
HYALOMYODES nov. gen.
Head much like Hyalomyia; front very
narrow, slightly widened at vertex, much more widened toward insertion of antennae, at narrowest about one ninth width of head in both sexes. Face widening from front at same angle as latter, so that the two opposite boundaries of the face and front diverge uni- formly from each other from the narrowest part of the front to a point very near the oral

margin. Sides of face extremely narrow,
cheeks but little wider, the eyes thus descend- ing very nearly to oral margin. Oral mar- gin distinctly protruded anteriorly, vibrissal angles situated distinctly above oral margin, facial ridges with only several small bristles above and immediately next to the vibrissae, which latter are not strong but are distinct from
the row of other bristles below them,
and slightly decussate. Antennae reaching a little more than half-way to the oral mar- gin, third joint about once and a half as long as second.
Arista bare, thickened on basal
third, I-jointed at extreme base. Frontal bristles rather weak, descending only to in- sertion of antennae. Proboscis not long, moderately stout, labella developed ; palpi filiform, very slender but elongate. Thorax distinctly narrower than head, with a few bristles ; scutellum subti-iangular, with three pairs of bristles. Abdomen broad round-
ovate, very distinctly wider than thorax, less broadened in 8, vaulted, the tesgiim convex, venter almost always concave, furnished with rather numerous weak macrochaetae. Legs
not stout, moderately long. Wings longer than abdomen, apical cell long petiolate, the petiole but little shorter than apical cross vein, fourth vein bent in a curve to third hardly more abruptly than in Hyalomyia.
Hind cross vein nearly stmight, longer than apical cross vein, nearer to small cross vein than to curve of fourth vein. Tegulae large, the upper scale about one fifth size of lower. Hyalomyodes weedii nov. sp. Length of
body, 4 to 4.5 mm. ; of wing, 3.5 to 4 mrn. Frontal vitta velvety black, taking up nearly all of front, widening behind and before with the width of front; the extremely narrowed sides
of front, the sides of face and cheeks
silvery white ; facial depression silvery. Antennae and arista black, palpi fulvous. Thorax soft deep black, with a golden brown shade in oblique lights, humeri and pleurae cream colored, or silvery with a slight golden shade. Scutellum wholly black. Abdomen
black, second segment with a median vitta and a narrow anterior border silvery pollinose with a slight golden shade, the border widen- ing laterally; third segment same, but with the pollinose border more widened and later- ally reaching the posterior border of segment, thus leaving on the posterior half of the seg- ment an irregular black area on each side of the pollinose median vitta; anal segment entirely pollinose. First segment with a median marginal pair of bristles, second with a median marginal and discal pair, third and anal segments each with a somewhat irregular discal and marginal row of weak macro-
chaetae. Legs black; claws and pulvilli
short in 9, a little elongate in 8. Wings hyaline, slightly grayish ; tegulae tawny yellowish

seems to be little difference
the sexes, the 8 having the
ittle elongate while there is no
)le difference in width of front.
Described from three specimens, 2 9
and I 8, Hanover, N. H., from Dr. C.
M. Weed ; and 2 $ , Fi-anconia, N. H.,
from Mrs. A. T. Slosson. I have seen
this peculiar fly as yet only from New
Hampshire.
NOTE.- Since sending the above in for
publication, I have found in a sending from Mr. C. W. Johnson, of Philadelphia, two
more specimens of this fly. One of these is a 8, from Franconia, N. H., collected by Mrs. Slosson. The other specimen is from Montgomery County, Pennsylvania, and was collected July 17.

9. The female only differs from the male in its larger size, the greater obscurity of the median band on the primaries, and the
greater distinctness of the subapical marks. Expanse, 3, 25 mm. ; 9, 32 to 38 mm.
LAELIA, Steph.
86. L. Jty^oZemis, sp. nov. 3. Front
whitish. Antennae testaceous. Thorax and the forward portion of the abdomen on the upper side vinaceous. The abdomen at its extremity is tipped with white. The lower side of the body is whitish. The legs are pale fawn. The primaries are vinaceous with a darker longitudinal streak running' from the base below the cell and curving outwardly toward the apex. The costa near the base and the apex are whitish. There is a small spot in the middle of the cell, a somewhat larger spot at the end of the cell followed by a zigzag very narrow, transverse lim bal line, which beginning on the costa three-fourths of the distance from the base runs inwardly to the middle of the inner margin. That
portion of this line which lies between the submedian and the first median assumes the form of a V-shaped mark with its point turned outwardly. In some specimens there is a
faint curved transverse basal line. The
markings of tlie primaries are somewhat
variable and in some instances the large spot at the end of the cell in the primaries is obsolete. The secondaries are uniformly
pure white above, and both primaries and secondaries are white below with the fringes of the primaries light brown checked with gray.
9. Like the male, but the markings of
the fore wings in the specimens before me are more obscure.
Expanse, 3, 33 to 40 mtn. ; 9, 45 mm.
87. L. (?) barsineides, sp. nov. 8.
Antennae long, culmen white, and pectina- tions grey. Palpi and head pale luteous. Abdomen brown above. Thorax and abdo-
men pale yellow beneath. Legs pale lute- ous, the tibiae encircled on the middle by a brown band. The primaries are pale luteous marked with ferruginous, somewhat after the style of some species of Barsine.
There is a
broad ferruginous subbasal band, an oblique oval annular spot at the end of the cell and a small spot above it on the costa. A broad irregularly curved and geminate ferruginous submarginal band runs from the apex to
the inner margin followed by faint brownish marginal lines. The secondaries are uni- formly pale buff, semi-translucent. The
under sides of both wings are pale buff, the markings of the upper side of the primaries being faintly indicated on the under side. Expanse, 23 mm.
I refer this species with some doubt to the genus Laelia, owing to the fact that the antennae are heavier than in most species of the genus, and the wings are narrower than in typical Laelia.
8. L. lignicolor, sp. nov. 3. Palpi,
front, and thorax pale reddish-brown, abdo- men paler. Body whitish beneath. Legs
pale fulvous. The primaries are wood-brown with the basal third darker, a darker spot at the end of the cell, and a broad diagonal line running from the apex to the middle of the base followed by a curved series of sn~all black dots running likewise from the apex to the inner margin. The posteriors are uni- formly reddish-buff. The under side of both wings is pale buff. The secondaries have a discal dot at the end of the cell and an obscure submarginal series of fuscous mark- ings. Expanse, 27 mm.
89. L. sefiuotdes, sp. nov. $ Palpi,
front, and thorax pale luteous. Abdomen
pale fawn, under bide lighter. Legs and
antennae concolorous. The primaries are
pale luteous with a small brown dot beyond the end ot" the cell followed by another near the apex and with three similar spots, one

below the cell before the origin of the first median, the others on the middle of the
median interspaces. The secondaries are
whitish, semi-diaphanous. The under side of the wing is much as the upper side with the dots on the primaries less distinct. Expanse, 25 mm.
90. L. ocellata, sp. nov. 3. Palpi pale
brown, tipped with orange.
Front luteous.
Antennae with the culmen whitish, the pec- tinations gray. Thorax vinaceous. Abdo-
men brown above. Lower side of body whit- ish. Legs pale fawn marked with light red- dish. Primaries wood-brown with a small
black spot below the cell near the base and a large brown spot at the end of the cell, which is accentuated on the lower side by a white semi-circle, and has in it one or two small black marks. Beyond this is a very narrow brown line beginning on
the costa
three-fourths of the distance from the base curving inwardly regularly to a point below the cell, and then running diagonally to the inner margin at a point one third of the dis- tance from the base. The apex is marked
with a subtriangular diffused whitish spot, which is crossed by a subapical series of three black points. The fringes are concolor- ous checked with dark brown., The upper
side of the secondaries is pale ocli~~aceous with a submarginal band of fuscous mark- ings. On the under side both wings are very pale buff. Both have a large discal spot at the end of the cell, and both have a sub- marginal band of blackish dots and lines. The fringes are as upon the upper side.
Expanse, 28 mm.
AROA, Walk.
91. A. nigr@ic/a, sp. nov. 8. Antennae
testaceous.
Body blackish with the segments
of the abdomen marked with whitish. The
under side of the body is white.
Legs white,
the femora and tibiae margined with black. Tarsi ringed with black. Primaries smoky- black crossed near the middle by two curved bands of darker black and with some obscure whitish markings near the inner margin.
Secondaries white, fuscous at the base, with the outer angle broadly tipped with black and the outer margin spotted with black.
On the
under side the primaries are whitish at the base and on the inner margin, while the
apical half is black. The apex at the tip is slightly paler. The secondaries are as on the upper side.
Expanse, 34 mm.
This species is allied to A. tervzinalis, Walk., but is very distinct.
92. A. lafa, sp. nov. $. Antennae
testaceous. Front white. Palpi white tipped with dark gray.
Patagia white, each with a
small black spot in the middle.
Thorax and
abdomen whitish above, white beneath.
Primaries white with a double transverse basal line; a dark oval mark in the middle of the cell; a broad transverse band beyond the end of the cell curved and scalloped out- wardly and inwardly; beyond these a series of moderately large and somewhat diffuse submarginal hastate markings. The margin has a blackish dot at the middle of each inter- space. The secondaries are pure white with faint brownish marks on the margin at the middle of the interspaces. The under side of both wings is white.
The primaries have a
slight subapical brown shadow upon the
costa and a series of brown marginal
spots
on the interspaces. The secondaries have similar marginal spots, but much smaller and less distinct than on the primaries. Expanse 42 mm.
LIPARIS, Ochs.
93. L. (i?) muscosa, sp. nov. 3. Antennae testaceous. Palpi and front dark brown.
Upper side of thorax and abdomen gray. The abdomen with two black tufts on the dorsal line behind the thorax. Under side of the body paler. Legs whitish, banded with dark brown. Primaries pale greenish-gray with an oblong lunular brown mark at the end of the cell, some brown marks at the base suc-
