DEILEPHILA EUPHORBLE. 33 



I put the pupaB aside to wait for summer, but before 

 that time came they had died. 



Of course I cau say nothing of the larva when young, 

 but I may notice the appearance of the two smaller 

 ones when they first came to me. The ground colour 

 of the smallest was black; the next in size was blackish- 

 green, with a multitude of small bright yellow dots, 

 contrasted with larger spots of yellow tinged with a 

 rosy hue in the centre ; for the rest I shall describe 

 one full-grown larva, and mention the variations of 

 detail in the others, as each preserved its individual 

 points of difference to the last. 



The full-grown larva measured from three to three 

 and a quarter inches in length, being in proportion a 

 trifle more slender than the larva of D. gain, though 

 otherwise similar in form, being plump and cylindrical, 

 tapering considerably from the fourth segment to the 

 head, which is the smallest segment, and is rounded in 

 outline; tapering a little also at the two hinder seg- 

 ments, the twelfth having a rough, blunt-tipped horn 

 curving a little backwards ; each segment from the fifth 

 to the twelfth is subdivided into seven rings by well- 

 defined wrinkles, the front ring being equal in width 

 to three or four of the others. The skin was generally 

 smooth and shining ; the anal prolegs larger than the 

 ventral prolegs and of a squarish form ; the segments 

 appeared more plump and swelling on the ventral than 

 on the dorsal surface. 



As to colour, no two individuals were of the same 

 type, the ground colour of the skin only varying in 

 intensity from a bronze-green to a deeper blackish- 

 bronze. The head was blood-red, the mouth and base 

 of papillae pale yellow, the former margined above and 

 below, and the latter surrounded with black ; the dorsal 

 stripe was blood-red in colour, widening on the second 

 segment in a curve down either side, suggestive of a 

 plate, but thence continuing of nearly uniform width 

 to the anal flap, which was likewise red. The horn
