BOMBYCID^. LASIOCAMPA. 39 



of Lasiocampa, combined with the strongly bipectinated antennae of 

 the males, and scarcely pilose tibise, well distinguish that sex from 

 the rest of the Bombycidse; and the females are known by having 

 the abdomen very robust, scarcely tufted, the antennae straight, the 

 legs slender and scarcely pilose ; the wings entire, and not sub- 

 diaphanous. 



Sp. 1. Rubi. Alls cervinis immaculatis, anticis strigis duabus albidis. (Exp. 

 alar. $ 2 unc. 4 — 6 lin. : $ 2 unc. 6 — 8 lin.) 



Ph. Bo. Rubi. Linne.—Don. iii, pi. 87.— La. Rubi. Steph. Catal. No. 5986. 



Male entirely of a lively reddish-fawn colour above ; the anterior wings, with 

 the posterior margin, rather darkest, with two nearly parallel oblique whitish 

 streaks. Female pale ashy-brown; in other respects similar to the male, 

 excepting the slender antenna;. 



Var. li. The anterior wings with one (the hinder) posterior striga above. 



Var. y. The anterior wings with the two strigae united, and forming a broad 

 whitish band. 



The position of the strigae varies considerably. 



Caterpillar velvety black, with pale yeUow rings, when young; afterwards black 

 below, ferruginous above, with black rings : it feeds on the bramble, appearing 

 in September, hving throughout the winter, and changing in the spring to 

 a dusky pupa, annulated with luteous, in an elongate silken foUiculus : the 

 imago is produced towards the end of May, or beginning of June. 



The habit of this species somewhat removes it from the genus : which is also 

 apparent from the structure of its foUiculus, which closely resembles that 

 formed by the larva of Gastropacha. 



Not uncommon in woody plains and extensive heaths throughout 

 the metropolitan district, and in other parts ; at Shooter''s-hill, Hert- 

 ford, Wimbledon-common, &c. I have frequently taken it. " Near 

 Matlock."— i^^y. F. W. Hope. " Epping.'"— i//-. H. Douhleday.

 lineSque repandd lividi, posticis immaculatis. (Exp. alar. $ 2 — 4 lin.: 9

The radii of the antennae, head, thorax, abdomen, and wings of a rusty-griseous,

 cream-coloured discoidal spot, and a livid or ocliraceous slightly flexuous line
