Bomhyces collected in Chili. 105 



edge. Full-fed about the end of October or beginning of 

 November. 



" Pupa. — Enclosed in a pear-shaped cocoon of buff- 

 coloured silk, open at one end {Saturnia-\\\.Q) , spun 

 among the leaves of the food-plant." — T. E. 



A pen-and-ink sketch by Mr. Edmonds represents the 

 bipectinated spines as deflexed on each side of the body 

 like the hairs on some other larvae. 



35. Hypei'chiria erythrops, Blanch. 

 "Larva. — Dull brown, clothed with prickly spines: 

 head dark brown and shiny; body dull greyish brown, 

 with indistinct subdorsal and lateral lines of dirty white 

 colour, and irregular pale dull orange lines immediately 

 above and below the spiracles ; the latter pale dull 

 orange, edged with black ; under side and claspers 

 greenish grey ; prolegs brown ; each segment armed 

 with six tufts of sharp prickles of a light brown colour, 

 tiie extreme tips dark brown ; these sting severely when 

 touched ; two tufts are subdorsal, two lateral, and two 

 spiracular. Food-plant, " Maiten," Bromelia, bramble, 

 &c. Gregarious when young ; a night-feeder ; hides by 

 day among dead leaves and rubbish near roots of food- 

 plants ; the young brood disperses as it grows older. 

 Full-fed beginning of December." — T. E. 



The two following new species are referable to the 

 Notodontidce ; the larvae were left in Chili to be reared, 

 and the moths forwarded quite recently to Mr. Edmonds. 



PSEUDOCERURA, n. g. 



Allied to Heterocampa, but with the general aspect of 

 Cerura ; thorax very flat above, very coarsely scaled ; 

 collar very deep ; basal hairy clothing of the abdomen 

 represented by an appressed expanded tuft on each side ; 

 the abdomen itself rather short, tapering rather suddenly, 

 almost to the extremity, strongly carinated along the 

 dorsal line ; anal tuft also carinated, slightly expanded ; 

 antennae rather thick, with very short ciliae along the 

 anterior surface ; legs rather long, thick, and coarsely 

 scaled ; primaries with nearly straight costal margin, 

 with convex subangulated outer margin and slightly 

 sinuous inner margin ; secondaries subpyriform.
