In Kirby's catalogue the American species, formerly referred to Arctia, are distributed irregularly under three generic names. As the species do not seem to be separable gen- erically, I adopt the oldest name for the genus, viz. Euprepia Ochs. (1810), under which name are found E. pudica Esp. and
E.fisciata Esp. Arctia Schrank is restricted

to A. villica Linn. and A. bieti Oberthur, while the species formerly referred to Eu- prepia, viz. E. caja Linn. and allies, are referred to Hypercompa Hubn. (Tentamen,
1805?) which is the same as Zoote Hiibn. (Verz., 1822 ?). The generic names of the catalogue may be used as subgeneric or
group names ; but the species must be better assorted than has been done. Apantesis
Walker must be restricted to A. nais and decoyafa; Callarctia Packard will stand for the species with the veins lined with pale scales, while the name Cymbalophora Ramb. can be used for the American allies of E. ċ´pudic Esper, of which the present species, E. HakeiGrt., is one.
The following notes were made on the
larvae :-
Egg-.-Sub-conoiJiil, flat at base, perfectly smooth even under the microscope; shining pale yellow; diameter 0.8 mm. The shell is transparent, so that the little larva can be plainly seen within. The eggs are laid un- attached, so that they readily roll about. First 4tage.-Head slightly bilobed, black and shining, paler around the mouth ; width 0.4 mm. Body normal, whitish, the cervical shield black; hairs evident, single from the concolorous warts, black. Later the warts become black, large and distinct.
Second stave.-Head bilobed, shining light brown, blackish at vertices of lobes and around mouth; eyes black; width 0.6 mm.
Body very pale brown, with an obscure,
slightly whitish, dorsal line; warts large with many long, spreading, blackish hairs; cer- vical shield and warts black. There is the appearance of a subdorsal line, caused by the contrast of the pale ground color with the warts of rows 2 and 3.
Third stage.-Head bilobed, shining pale
brown, black in front centrally and on vertex ; ocelli large, black; width 0.8 mm. Body
brown, with a rather broad whitish dorsal line; warts very large, black, with abundant long, spreading, black hairs, especially long posteriorly and supplemented by a few very long white hairs, arising from joints 12 and 13. Cervical shield shining blackish brown; thoracic feet black. The larvae are very active in running to hide beneath leaves, etc., if disturbed.
Fourth stage.-As before; width of head
1.1 mm. The dorsal line is straight and
even, well defined, nearly white. The body is a little mottled on the sides, dark, nearly black on the back.
Fzj% stage-Width of head 1.5 mm. Body,
warts and hair all black except a narrow and rather faint reddish dorsal line, broken in the segmental incisures. Hair bristly, stiff and barbed, of irregular length. The body is pale ventrally and in the incisures ; thoracic feet black, the abdominal ones pale. A few very long white hairs as before.
Sixth stage.*-Head shining pale brown,
black all over the vertices of the lobes and in front on each side of the central suture and around the ocelli ; antennae and mouth pale brown; width 1.75 mm. Body black above,
blackish brown below, mottled with paler, with an obscure reddish brown dorsal band ; warts deep black, tuberculate; hair short, but dense, bristly and barbed, deep black except from wart 6 where it is whitish. A few (about four) very long white hairs aris- ing from joints 12 and 13, directed posteriorly. Later the body becomes entirely deep black above with no dorsal line; the subventral hair is reddish.
Eggs received from Mr. J. B. Lembert,
Yosemite, California.
As the accurate determination of species of Euprepia is difficult and attended with
chances of error, I append a description of the moth from which these eggs were ob-
tained.
*Not the normal sixth stage, as the width of head .
should have been 2.2 mm.
The larvae were bred under
disadvantageous circumstances, being carried from Portland, Or. to Plattsburgh, N. Y., where they finally died from the effects of the hot weather and confinement. The stage above described is an inter- polated one and not the normal last stage. The species probably has but six stages naturally.

$. Head and thorax above yellowish
salmon color with the usual black marks; abdomen deep ocher yellow with a dorsal and lateral row of confluent black spots; below, the thorax, abdomen and legs are entirely black. Fore wings deep black with salmon colored bands, each narrowly bordered with yellowish on both sides. Basal half line absent, represented on one wing by a few scales on the costa; trans.-ant. line reaching from costa to internal margin, rather narrow, dilated at both ends; median band reaching ċ´fro costa to just below the longitudinal sub- median band, ending in a point; trans.-post. line slightly angulated, reaching only to the submedian band ; terminal angular band
(W-mark) normal, joining the trans.-post. band at about its middle; fringe and internal margin narrowly salmon color, Hind wings scarlet ("flame scarlet," Ridgway, plate vii, fig.
14) with a narrow uneven outer black
border, obsolete before internal angle ; three A MONOGRAPH OF THE NORTH AMERICAN
TACHINIDAE.~ Prof. C. H. Tyler Townsend
is at present engaged on the preparation of Part I of a monograph of the North American Tachinidae, which he hopes to have ready for publication in about two months from this date. The part will embrace the Phasii- dae, Gymnosomatidae, Ocypteridae, and
Phaniidae. Any persons having material
in any of these groups will confer a favor by sending it to Mr. Townsend, who will return it fully determined. The monograph will
aim to represent the entire fauna of North America north of the Isthmus of Panama,
including the West Indian forms. Subse-
quent parts will follow in the course of time. Mr. Townsend has been engaged on this
work for some years and has already a large amount of material on hand, but he is de- sirous of examining all possible specimens of the above groups, from within the limits stated, before sending the manuscript of part 1 to the printer.
submarginal rounded-triangular spots, the last one at anal angle; two discal elongate spots, the inner one much elongate and at- taining the costa, the outer, small ; a large spot on the middle of abdominal margin and a small one at base. All the black marks narrowly bordered with yellowish. Fringe narrowly yellowish salmon. Below, the col- ored parts of both wings are orange (Ridg- way, PI. vi, f. 3) with the black parts as above. Expanse 42 mm. The moth here
described differs from all those referred to in the synonymy given above in the absence of the basal half line, and I propose for it the varietal name $e~$icta.
The character, though slight, is usually of such diagnostic value in the case of 23. blah' that its absence in this form seems to warrant the different designation.
Prof. drench has
described some ninths of this form as Arctia geneura Strk. (Can. ent., xxi, 162).
ENTOMOLOGICAL No~~s.-Miall and Ham-
mond have just printed a paper in the Tran- sactions of the Linnean society of London on the development of the head in Chirono- mus, which will be found interesting from its representing a type intermediate between the apparently widely different types of Corethra and Musca, hitherto the best known. A
great part of the head of the imago arises from paired invaginations extending far into the larval thorax.
A feast of Chionobas is offered in the new Part of Edward's Butterflies of North Amer- ica, for it is devoted entirely to four species of that genus, of which the tiansfonnations of two, C.*a and C. brucei, are described in detail and figured profusely with exquisite skill, admirably bringing out their distinctive features. Considering the home of these
insects, one cannot too strongly commend the perseverance which has culminated in such a series of plates as these. The text, too, is full and interesting, indicating curious
