PSYCHE. 



[January 1893. 



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 Hiibn. (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. fiat's and 

 decorata; Callarctia Packard will stand for 

 the species with the veins lined with pale 

 scales, while the name C vmbalophora Ramb. 

 can be used for the American allies of E. 

 pudica Esper, of which the present species, 

 E. blakei Grt., is one. 



The following notes were made on the 

 larvae : — 



Egg. — Sub-conoidal, 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. Tire eggs are laid un- 

 attached, so that they readily roll about. 



First stage. — 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 stage. — 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. 



Fifth stage. — Width of head 1.5 mm. Body, 

 w r arts 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.
