company ; but as they ^vow older they separate and feed 

 alone, 'I'he larva is full-fed by the end of May or beginning 

 of June, and then usually rests in a perfectly straight posi- 

 tion. Head rather narrower than the body, hairy : body 

 almost uniformly cylindrical ; every segment from the 2nd 

 to the 13lh, both inclusive, has two dorsal warts placed 

 transversely ; these are Hat and but slightly elevated above 

 the surrounding skin, and in some specimens it is diffi- 

 cult, if not impossible, to detect them while the larva is 

 living; and on each side of each segment, just below the 

 spiracles, is another wart somewhat linear in outline, and 

 equally flat with those on the back ; every part of the body is 

 clothed with hairs ; those emitted by the dorsal warts are 

 particularly long and conspicuous. Colour of the head black, 

 its hairs gray ; of the body black, with an obsciU'e purple 

 tinge es])ecially observable on the sides and in the incisions 

 of the segments ; the 2nd segment has a large quadrate dor- 

 sal blotch, which, as well as the warts already described, are 

 of an orange-brown colour; on each side of each dorsal wart 

 is a transversely elongate marking of the same colour, but 

 still more brilliant, sometimes of a bright orange ; of these 

 lateral ornaments the anterior is invariabi}' the smaller : the 

 ventral surface is grayish smoke-coloured ; the legs black ; 

 the claspers smoky, tinged with pink ; the longer and more 

 conspicuous hairs are black; the shorter and more numerous 

 ones paler, almost white. A very beautiful and vt;ry variable 

 larva ; in some examples the orange markings on the sides 

 are tinged or irrorated with while, and alternate with pure 

 white amorphous blotches, which form a broad iiiegular par- 

 ticoloured stripe on each side. The full-fed larva usually 

 descends to the ground in July, and form's a somevvhat com- 

 pact cocoon, attached to roots just below the surface of the 

 ground, or sometimes to twigs lying on the surface. The 

 moth appears on the wing in September. 1 am indebted for 

 a supply of this beautiful larva to Mr. Doubleday and several 

 other entomologists. — Edward Neivinan. 



Descri/jtion of the Larca of Cuciillia ui)ihra1lca. — The 

 egg is laid on the leaves of Lactuca virosa (lettuce), Sonchus 

 arvensis, S. oleraceus and S. palustris (sowthistles), in June 

 and July, and the larva, which emerges in July, devours the 

 leaves of these species, as well as those of the garden lettuce.
