[August ~Sqb,
From the foregoing I believe that the
status quo of Apatela remains virtually
unclianged since my paper in Pipilio,
iii, I 16, 1883. The list there given by me of unidentified names can only be
safely changed to-day by the elimination of two of Harris' posthumous names
based on larvae : UZm' Harris, being
based on larvae belonging to morzila,
as Prof. Smith tells us, and is therefore a synonym ; while $rum' Harris may
be used for the species called by me
clarescem, since the evidence is that
Guenke's clarescens is not mine,
although exactly what it is is not made
out unquestionably. As before, the
" future monographer" whom we are
all expecting (I wish I had the naming
of him) must busy himself with the
question of what Guen6e really described under the names: spintg'era, felum,
intermj5tq and longa, and he will do
well to reject infemi'fita altogether, as founded on a figure which, in this dif-
ficult genus, will hardly be admitted as a proper basis for a description and
name. It will shorten his labois by so
much. He will have also to decide
what Abbot intends by his plates of
aceris and hastulifera, and he will
have an easier task to make out Harris'
remaining name salicis. I å´shal be
glad if the other names in the cata-
logue, which are mainly based on my
identifications, receive his confirmation. But he must conscientiously compare
Gucn4c's text with the material,
inas-
much as names derive their authority
from literature, not from labelled speci- mens, however convenient these may
be as a substitute for the somewhat
arduous labor of making a specimen
function " to a description.
Note.- Since finishing this article I have received a letter from Mr. Harrison G. Dyar, who kindly Informs me that the larvn figured in Hnrris' Correspondence under the name salictS, belongs> to aSiimia,
If there is any
difference between our northern species and oblinita as figured by Abbot, we have a
name in salici.~ for the northern form. Dr. Thaxter called my attention to material col- lected by him in Florida, but I was not able to find any points of specific distinction as compared will1 northern ohlinz'ta.
PREPARATORY STAGES OF COSMOSOMA AUGE LINN BY IIARRISON G. UYAR. NEW YORK.
A full fed larva was found at Lake Worth, Florida, late in December and eggs were
obtained from severs11 female moths found flying over the flowers of some vines of Mtka;i/it scaudem growing in the swamp.
lam much indebted to Mr. F. Kinzel of Palm Beach, who has kindly sent me leaves of
the food plant every few days, and thus
enabled me to raise the larvae nnd observe their stages.
Eggs.
Rather low conoidal with flat base;
smooth, shining, translucent, waxy white, faintly tinged with yellow; no marks under a hand lens. Under a half-inch objective the reticulations are linear, rounded, hexagonal, irregular, even four-sided, scarcely raised. Diameter 0.8 mm., height 0.6 min. Usually laid singly on the young leaves of the food plant. Duration of this stage eight days. Stage I. Head colorless, eyes black,

month brown; width .3 mm.
Body entirely
colorless, the hairs single, rather long, white; anal feet rather large, divergent; length 2.5 mm. Later certain of the dorsal hairs (of tubercle ii) and all the warts become blackish. Afwr feeding the body
is greenish from the food showing by trans- parency, the head, thoracic feet and joint 13 slightly yellowish. "Warts normal, single haired, iv behind the spiracle, vi absent, an oval dusky leg-plate with several hairs; on joints 3 and 4 tubercles ia, ib and iia from a single area, iih weak, remote, iii and v absent, vi with two hairs. On joint 13 i, ii and iii from a single area, iv and v from a single area, the anal pl;Ue wilh 10 hairs. Sfqe 11. Head yellow, shining, ocelli
black; width .4 n1m. Body whitish, yellow at the ends as in the mature larva; warts all black, neatly defined, several, haired, arranged as in the mature larva, the sub- primaries present, normal. Hair black and white mixed, the white the mo&t numerous, spinulated ; warts iv and v on joints 5 and 11 a little larger than elsewhere, the hairs, however, all alike. Leg-plates pale.
Sfag-e III. Head .6 mm., whitish, the
ends of the body yellow; warts black, all much as before, the hairs quite dense, but not at all obscuring the body, v~iriously curved, from six to ten arising from each wart.
Sffvs-e IV. Head .8 mm. The same, the
warts distinct, neatly defined; hair a little thicker laterally on joints 5 and 11, indicating the tufts, but no plumed hairs present.
Sfup V. Head 1.2 mm. There is no
change; length about 14 mm.
Sfnp VT. Head 1.7 mm. Similar to the
mature larva except for the absence of the side tufts, though warts iv iind v on joints 5 and 11 hear an unusual number of black hairs, thus serving to suggest the tufts. The hairs are all alike, black and white, of even length, abundant, but fine, not obscuring the body. A distinct orange mark on joint 12 before the spiracle. A few long hairs
antei-iorly.
Stqe VII. Mature larva. Head yellow,
ocelli black, mouth brown; width 2.4 mm. Body yellowish on joints 3, 4, 12 and 13> joint 12 most distinctly so. as also the feet; warts and spiracles black; i to iii normal, iv small but distinct, behind the spiracles, v and vi normal, none large. Hair dense,
fine, of even length, black, and white mixed, the white predomiiiiiting, the appearance consequently pale gray, sparsely dashed
with black. On joints 5 and 11 dense con- colorous tufts laterally, the same length as the other hairs and also white and black, but heavily feathered, the black ones plumed; these tufts arise from warts iii and iv. On ihe thorax there is one large wart above the stigmata1 wart, hut it is not. elongated nor of unnsi:al size; a few long hairs from it overhangthe head. On joints the cervical shield has two tiny warts on each side, a wart at the edge; a stigmatal and a subven- tral wart. Skin translucent, without marks. Cocoon. Large, elliptical, attached only by one side to the supporting object a% in Halisjdota cayyae, composed of silk and the larval hairs, transparent, regular, light yel- low, intermixed with black plumed hairs; size 17 x g mm.
Ptifa. Rounded, shaped as in Halisidota, the incisurcs notinovablc. All pile yellow, spiracles, eyes and a row of dorsal marks black. The pupa skin is very thin, but all the essential points indicate a11 Arctian affi- nity. not Lyniantriid as stated in Ent. Ainer. (vol. i, p. 86) where the editor was evidently misled by the transparent skin of the empty pupa. His statement should be reversed.
Imago in 21 days.
NOTE ON DIONYCHOPU~.~ In Psyche for
July Mr. R. A. Cooleyquestions the accm->icy of the results of Dr. W. Donitz in respect to the structures in DiofycItopus duous, Men. which could be capable of producing a sound heard by Dr. Donitz. This has led me to
examine the species, and I believe that Mr. Cooley is entirely correct. The spiny patch is present on the under side of the fore wing
