136 THE ENTOMOLOGIST. 



on the base of the leaf upon which they rested, in company 

 similar to before hybernating. 



Directly after emerging from hybernation, and after second 

 moult, they are very small, only measuring ^ in. long, and 

 similar in all respects to previous stage, excepting the hairs 

 are longer, forming a somewhat dense covering. 



Just before third moult it measures J in. long. 



First one moulted, third time, April 9th, 1905, others con- 

 tinued moulting during the next few days. 



After third moult, and a few days before fourth moult, it 

 measures f in. long. The body is nearly cylindrical, and trans- 

 versely wrinkled ; the dorsal surface is black, with a sub-dorsal 

 longitudinal band, composed of orange blotches and speckles, 

 which cuts up the black into three stripes ; the sides and 

 ventral surface are olive- drab, minutely speckled with pale 

 ochreous ; on the dorsal surface are numerous slender bright 

 orange hairs, and longer silky pure white ones scattered over 

 the body, as well as a large number of shorter ones ; all the hairs 

 have shining, black, bulbous bases, each encircled by an ochreous 

 ring ; the head and legs are black, the former beset with hairs. 



They rest together in compact parties, dispersing to feed 

 each time, and strip the twigs, leaving only the midribs of 

 the leaves, beginning first on the leaves at the end of the 

 branches and feeding downwards, returning to the tips to rest, 

 and spinning webs each journey, backwards and forwards, form- 

 ing a carpet of silk over the branches along which they travel. 



First one moulted the fourth time April 21st, and all passed 

 through this moult by the end of that month. After fourth 

 and last moult, fully grown, about two hundred and eighty days 

 old, the larva measures from IJ in. to If in. long. During 

 this last stage it increases greatly in size, being only f in. long 

 when first moulted, and the skin is rough and ample, which 

 becomes stretched and shining when fully grown. In shape it 

 is almost cylindrical, but slightly attenuated at each end. The 

 dorsal surface is black, with a sub-dorsal, longitudinal, ochreous- 

 orange band, composed of numerous speckles ; in the centre of 

 each rises a fine hair, with a tiny black shining bulbous base ; 

 all the hairs, excepting the white ones, are either orange or 

 amber, while the black surface is very finely granulated and 

 sprinkled with shorter and very fine black hairs, and a few long 

 wavy white ones, with an ochreous ring encircling the base 

 of each ; the whole surface below the sub-dorsal black band is 

 very glossy, of a purplish grey colour, thickly sprinkled with 

 whitish grey spots, each encircling a fine white hair, the entire 

 surface of the body being hairy ; the head is dull black and 

 covered with black hairs ; the anal segment, including the 

 claspers, is also black, the other claspers are unicolorous with 

 the body ; the legs and spiracles are shining black.
