PTEROPROEUS LOEWII. 359 



Var. 2 has the ground colour brownish-yellow ; the 

 head is also brownish-yellow, freckled with brown ; the 

 medio-dorsal stripe is broad bright purple; the sub- 

 dorsal stripes are also broad, but of a much less 

 distinct dull pale purple, and having a fine white line 

 running through them; a narrow purple line, edged 

 above with white, extends along the spiracular region. 

 The ventral surface, legs and prolegs are uniformly 

 pale yellowish-brown. 



It feeds on the flowers of Erythrxa centaurium. 



The pupa is slender, and nearly (if not quite) as 

 long as the full-grown larva ; it is of almost uniform 

 width, the last two segments only tapering to the anal 

 point. It is glossy and cylindrical, but there is a 

 depression on the thorax and front abdominal seg- 

 ments ; the snout and top of the thorax are prominently 

 and sharply defined ; the leg-cases extend a long 

 distance down the front of the abdomen, but before 

 the end, become detached from it. The ground colour 

 is yellow, but is almost hid with a deep pink, which is 

 suffused all over the surface, and almost forms a stripe 

 from the head through the abdominal segments ; the 

 wing- and leg- cases are dingy olive, tinged with pink. 



All the imagos — a fine series — emerged from the 

 23rd of August to the 1st of September, 1883.

Plate CLXIII, fig. 9. 



The larva of Pterophorus plagiodactylus, when full- 

 grown, is about five lines in length, of moderate pro- 

 portion, neither stout nor slender, tolerably cylindrical, 

 tapering a little posteriorly ; the head is rounded and 

 rather smaller than the second segment, of a very pale 

 colour and shining ; the body is very pale olive-yellow, 

 with a conspicuous brown dorsal line attenuated at
