426 MR HARDY ON DESCRIPTIONS OF SOME 
the lateral margin, some fuscous spots excepted, a row of faint 
lateral spots, sides and tip of the penultimate, and the apical 
segment entirely, yellow; oviduct brown; breast yellow, with a 
black patch on its sides, anda larger one posteriorly ; legs bright 
yellow, the anterior and intermediate thighs with a fuscous patch, 
and a ring composed of lengthened dots; their tibie with a very 
narrow line and some fuscous spots; hinder femora with a fuscous 
line continued both ways in spots, tibiee with two rows of minute 
spots, and an interior dark line; tips of the tibie and tarsi fus- 
cescent. Length 1+ line. 
This which is from the sides of the Derwent, is evidently an 
imperfectly developed insect, and [have another ofa greener tint 
from Berwickshire, agreeing with it in this respect. From the 
latter district, however, I have a third, which I consider to be 
the true representative of the species. It is alittle broader, and 
the elytra pass considerably beyond the apex of the body; the 
middle of the face is ribbed with black lines, leaving a triangular 
yellow space nearest the tip, the upper rib is represented by dots 
only, the middle of the thorax, and the elytra, are of a light 
pleasant green, the latter subhyaline posteriorly with a blackish 
arched streak within and encircling the apex ; wings nigrescent 
with dark nervures; breast and abdomen deep pruinose black, 
the latter above with a line before the apex, and some specks on 
the tip above and beneath, yellow; legs yellow, fore coxe, except 
at the tip, tips of the tibie, the tarsal claws, tip of the basal, and 
the two last joints of the posterior tarsi entirely, and a spot 
within the apex of the posterior femora black; in other respects 
like the preceding. Length 1? line. 
The effects of incomplete developement in blanching the wings, 
is a@ curious circumstance, but I have observed it in another 
species, which, under the forms named by Curtis, A. sulphurea, 
tenwola, craticula, and maculipes, retains’ the slaty tint of those 
organs, but in its “halfmade up” state, which I consider to be 
A. unimaculata, and A. lata, of the author just cited, the colour 
is entirely discharged from them; in the last forms, the elytra 
are frequently so much curtailed as to leave a large portion of 
the abdomen exposed,
