FTEROPHORUS PLAGIODACTYLUS. 361 



larva called P. scabiodactylus by Mr. Gregson, which 

 were on Scabiosa columbaria. 



These larvae were three-eighths to half an inch 

 long. One was of a pale yellowish-green slightly 

 inclining to olive, the other a fuller and rather deeper 

 green, more the colour of the leaf of the plant; the 

 body is not very stout, and very slightly tapering to 

 the rounded hinder extremity ; the head is smaller 

 than the second segment, which last is less than the 

 third, so that it tapers in front from the third. There 

 is a faintly darker dorsal line or pulsating vessel, 

 though on the shining second segment this is repre- 

 sented as a double line of faint blackish, and on either 

 side of it on the subdorsal region is a black amorphous 

 spot. The head is much of the same tint as the body, 

 though faintly browner; the jaws are darkish brown, 

 with a rather large black spot at the lower side of 

 each cheek in the usual situation of the ocelli ; the 

 head is very lustrous in polish ; very faint indications 

 exist of a rather paler stripe along the subdorsal 

 region, but so softened at the edges as to be so ill- 

 defined as not to warrant its being noted until the 

 larva has fixed itself after being full-fed ; the whole 

 surface of the body is covered with very short bristles 

 of a dirty whitish colour, mixed in places or sprinkled 

 with a few blackish ones, notably on the second, 

 third, and fourth segments, and more sparsely along 

 the dorsal vessel and last segment ; in addition to 

 these which clothe the body are regular series of long 

 bristly hairs, dirty whitish, issuing chiefly from the 

 usual tubercular positions, sometimes in twos or 

 threes ; the spiracles are of the ground colour ringed 

 with darkish brown. 



These two larvae came with a bit or two of the leaf 

 of the plant ; one of them, the darkest and biggest, 

 fixed itself, being full-fed, on the 10th ; the other 

 died. 



The pupa, which I figured on the 27th of May, was 

 three-eighths of an inch in length, slender, attached
