costal spine, grayish-hyaline, opaque gray at base; apical cell very narrowly open at some distance before the apex of the wing ; fourth vein bent at an angle without stump or
wrinkle, the bend not sharp, apical cross- vein a little concave ; hind cross-vein curved, nearer to bend of fourth vein; third vein spined at base; tegulae white, halteres yel- lowish gray.

Differs as follows : Front nearly one-
half the width of head; frontal vitta broad, occupying one-third of frontal width ; three orbital bristles
(on one side, on the other
side only two) ; eyes more distinctly hairy, especially" on upper portions; claws and pulvilli hardly shorter.
Length of f 6 mm.; wing 54 mm.
$
7 mm. ; wing 6 mm.
Described from three f specimens,
and one
$ , bred from chrysalids of
Hyfhantria cunea, Las Cruces, New
Mexico. This species is best located in
Meigenia. The face, however, is not
almost perpendicular, the abdomen is
short and stout, and the macrochaetae
are only marginal unless on the anal
segment. It cannot be referred to
Mystacella, which has the eyes more
decidedly hairy.
Note on Phorocera firomiscua Towns.
Psyche, v. 6,84. This species was wrongly referred to Phorocera, my reason for the ref- erence being that the facial ridges are bristly for fully half their extent. But the eyes are very indistinctly hairy, the species agreeing in this and its other characters with Mei- genia.
It will be best, I believe, to refer to
it as Meigenia $romiscua Towns.

I have for some time considered this spe- cies improperly referred to Oedemasia, but I have never found the larva. Dr. Thaxter, however, has bred it, and writes me as fol- lows : " Oedemasta eximia resembles Coelo- dasys Zeftinoides* in coloring, but structur- ally is perhaps more like biguttatzis ($0- meae). When at rest it is greatly hunched anteriorly, and the furcate prominence on segm. 4 is very long. I should say it was surely a Coelodasys" (=å£c&i'zura)
I would place it next to 5. le9tinoides and near lanassa.

'Described in Ent. amer., vol. 6, p. 230. Larva. I have found this larva on Vibur- num Zedago, and it is certainly not an Oede- masia. It is without the red hump and black tubercules of 0. concinna, the body being smooth, with dorsal processes on the ist, 4th, and 8th abdominal segments ; the sides of the thoracic segments are green, but the usual V-shaped mark is, I believe, absent. I have not been able to obtain the larva re- cently for more careful description.

Larva. Third stage. Head black, with a
few short hairs; cervical shield bisected, black, as is the anal plate. Body yellow, with short pale hairs growing from black tubercles; joint 5 has a slight dorsal hump somewhat orange tinted, and with four
smooth black tubercles, these being part of a

transverse row of eight which each segment bears; joint 13 has a double row. The tu- bercles are not exactly in line, the two dorsal ones being placed anteriorly to the others. Faintly indicated geminate subdorsal and lateral brown lines; thoracic feet dark; length 12 mm.
Fourth stage. Head mahogany red more
or less shaded with black; furnished with short hairs; jaws black. Body yellow, a
single dorsal and geminate subdorsal, and lateral interrupted pale brown lines.
Black
tubercles as in the previous stage, but more elongated, the dorsal ones on the hump and the subdorsal ones on joints 3 and 4 especially so. There is also a slight hump on joint 12 with two elongated tubercles. Besides the four tubercles on each side are two more above the bases of the legs. The lines are obsolete behind joint 1 I, and the arrange- ment of the tubercles is confused. Cervical shield elevated, bisected; feet and anal plate black. Venter pinkish. The anal pair of
feet are held elevated.
As the stage advances the geminate brown lines become filled in with white, and a nar- row, interrupted brown line appears between the dorsal and subdorsal lines and between the subdorsal and lateral lines. The hump on joint 5 has a decided rose tint.
Fzyth stage. As in the preceding stage,
but the black tubercles are still more pro- longed, especially the subdorsal ones and the dorsal on joint 5. The hump on joint 5 is rose color, that on joint 12 yellow; the lines are black, except those that last ap- peared, which are brown, the geminate ones filled in with white, and all interrupted at the humps and obsolete on joint 13.
Anal
feet yellow, black at their bases.
Food-plant. Maple (Acer) . Larvae from
the Yosemite Valley, California, in August. I did not succeed in obtaining any moths from these larvae, as the stage ride out of the valley was more than they could endure ; but, from a comparison with Mr. Edwards' de-
scription, there is no doubt that they are 0.. salicis.
This species is the California representa- tive of the Eastern 0. concinua Sm. Abb.,. but seems specifically distinct.

Larva. Closely allied to Heterocam'pa
hinudata Walk., which I have elsewhere de- scribed.* Dr. Packard has described the
present species, but the larvae that I have seen do not agree with his description. I give the last two stages.
Fourth stage. Head higher than wide,
conoidal in outline, flat in front; pale green- ish, a curved band from the vertex to anten- nae dark crimson, centered with and bor- dered posteriorly by whitish. Labrum and antennae yellow ; jaws red brown ; width 2. I mm. Body thickest at joint 8 when at rest; feet normal, the anal pair elevated; on the anterior edge of joint 2 is a yellow line con- taining two brown points, which apparently represent horns of a previous stage. (In H. biundata the horns are present at this stage.) A narrow white dorsal line, edged with black on joints 2 and 3, obsolete on joint 13; a yellow, subdorsal line fading out anteriorly on joint 3,. edged inwardly with dark Brown on joints 12 and 13, and with white outwardly on the anal plate, narrowly and obliquely in- terrupted on the anterior part of joint 11. Between these two lines on each side is a supplementary dorsal line, which starts from the dorsal line on joint 5, and, running par- allel to it, joins it again on joint 8, imme- diately leaving it and running to the sub- dorsal line which it joins on joint 11, just posterior to the interruption. Faint traces ot a yellow stigmata1 line. The green of the * By error as H. subrotata Harv., Ent. amer., VI 209.

body is speckled with small black spots on the sides and on the back of the anterior seg- ments. Feet yellowish, the anal pair white with a narrow, longitudinal black line, and tipped with yellow.
Fzyth stage. Width of head 3.3 mm. Ver-
tical lines geminate, somewhat pulverulent on a white ground; color green, labrum
whitish, mouthparts purple-red ; ocelli black ; cervical shield narrowly yellow in front, smooth, without tubercles.* The body is
marked as before, the dorsal lines white, the subdorsal yellow, the stigmata1 absent. In one example the lines were partly obsolete especially in the fourth stage. As the pres- ent stage advances white shades appear in the space enclosed by the anterior supple- mentary dorsal lines and below the subdor- sal line on joint 13 while the subdorsal line becomes partly white. The lateral region of the body is dark green with purple dots, the dorsal region yellowish green with a general faint white shading. On one, a pink spot appeared in the subdorsal band on joint 7. Cocoon.
The larvae enter the ground and
spin an extremely slight web of silk.
Pupa.
Of normal shape, cylindrical, the
body punctured and cases creased ; antennae cases prominent. The cremastei- consists of two parallel spines, twisted a little near the snd and barbed, each bearing two little spurs the anterior one pointing inward, the poster- ior one outward. A curved row of six sub- cubical granulations is situated at the pos- terior edge of the thorax. Color shining mahogany red, darker on the cases. Length 19 mm ; width 5 mm.
The species is occasionally double-brooded and the winter is passed in the pupa state. Food'plants. Oak (~uerczts), Witch-hazel (Hamamelis), Hickory (Caryo), Chestnut
(Castanea) and Birch (Betula).

This species is double brooded. The moths of the first brood appear about the middle of June and from eggs laid by them the sum- mer larvae are produced which develop into moths towards the end of August. The sec- ond brood of larvae hibernate exposed on the stems of the food plant in the fourth or fifth lar- val stages and complete their transformations in the following spring, emerging as perfect insects in June. There appear to be six
stages.? There is not much change in col- oration except that during hibernation the color is of a uniform brown, resembling the color of the twigs of the food plants, and at maturity it is very variable, often decidedly greenish, resembling the leaves upon which the larvae rest. I have already noted how the larvae are protected from observation in their early stages.
The cocoon is formed of silk inside of the rolled edge of a leaf.
The pupa is cylindrical, a little flattened ventrally ; eyes and wing cases prominent; blunt at both ends, the head almost square; the abdominal segments not tapering but the last square and blunt. Cremaster a short thick rounded prominence which is smooth. The body is punctured dorsally, the wing cases finely creased. Color brownish yellow, the head, thorax and anal segment heavily shaded with blackish brown while the cases and back are also shaded, but less heavily. Eyes black ; spiracles dark brown. Length 11 mm. ; width 4 mrn.
Food plants - Viburmim acerz/oIi~tm, V.
lentago and V. denfatum.
Not uncommon on its food plants in Dutch- ess and Ulster Counties, New York.
