354 PTEROPHORUS PUNOTIDACTYLUS. 



clear purplish- pink ; the head is very dark sienna- 

 brown, almost black ; the smoke-coloured dorsal vessel 

 shows through as the dorsal stripe ; the subdorsal 

 stripes are clear white, and very conspicuous ; below 

 them is a narrow and interrupted white line, and 

 another about the same width, but which being tinged 

 with pink is not so pale, along the spiracles ; the hairs 

 are white. The ventral surface is semi-translucent, 

 yellowish-grey ; the prolegs are purplish-pink on the 

 outside ; the anterior legs are of the dark sienna-brown 

 of the head, but with paler rings. 



In Var. 2 the ground colour is bright pale green, the 

 markings the same as in Var. 1, except that the white 

 stripes are scarcely so conspicuous ; in some specimens 

 the smoky medio-dorsal vessel is tinged with pink ; 

 and the ventral surface and prolegs are of the same 

 bright green as the dorsal area. 



Some few larvao of those I received in 1884 were 

 intermediate between the two varieties. 



The pupa is attached to the food-plant by the tail, 

 and two somewhat curved pointed protuberances, 

 which spring from the back, give it a curious appear- 

 ance. 



As in the larva, there are two distinct varieties, a 

 purple form and a green form, but each having oblique 

 dark markings. 



In 1884 the first imago emerged on the 21st of 

 August, this year on the 6th of September. (George 

 T. Porritt, 7th November, 1885 ; E.M.M., December, 

 1885, XXII, 149—150.) 



Pterophorus hieracii. 



Plate CLXIII, fig. 7. 



I have at last discovered the larva of Pterophorus 



hieracii, for which I have searched for years, and 



which, I believe, has not hitherto been found in 

 England,
