358 PTEROPHORUS PHiEODACTYLUS. 



bristles ; spiracular, two small black contiguous warts 

 on each segment, emitting whitish hairs. The 

 prolegs and claspers are semi-transparent, dotted 

 with grey. 



The food is rest-harrow, Ononis ; it feeds on the 

 terminal leaves. Juue. 



The pupa is very like the larva ; it is attached by 

 the tail to the surface of a leaf of the food-plant, 

 generally on one of the terminal leaves. June and 

 July. (Richard South; Bntom., April, 1883, XVI, 

 75.) 



PtEROPHORUS LOEW1I. 



In the middle of August last, 1883, Mr. Thomas 

 Parmiter, of Cattistock, Dorchester, kindly sent me a 

 nice supply of full-grown larvae and pupse of Ptero- 

 phorus zojphodactylus Dup. = loeivii Zell. 



The larva is slightly less than half an inch in length, 

 and of proportionate bulk; the head is much smaller 

 than the second segment, the lobes rounded and 

 polished ; the body is cylindrical and uniform, 

 tapering a little posteriorly ; the segmental divisions 

 are fairly denned, and a tuft of several short hairs 

 springs from each of the indistinct tubercles. 



In colour there are two extreme varieties, and the 

 larva varies between these forms. 



Var. 1 has the ground colour a delicate pale green, 

 strongly tinged indeed with yellow ; the head is pale 

 yellowish-green ; the mandibles and ocelli are brown ; 

 the medio-dorsal stripe is dark green or purple in 

 different specimens ; the subdorsal stripes are yellow, 

 and there are two other fine but very faint yellow 

 lines, one above and the other below the spiracles ; 

 the segmental divisions are also yellow ; the spiracles 

 are black, very narrowly encircled with white. The 

 ventral surface, legs and prolegs are uniformly pale 

 yellowish-green.
