﻿imagine there were many species of the genus; I believe, how- 

 ever, that one only has been found in this country. 



The following is a description of the beautiful variety re- 

 presented in the Plate which is in the collection of my friend 

 Mr. A. H. Davis. 

 1. I. coleoptratus Fab. — Curt. Brit. EjU.pl. 44'9. 



Pale ochreous, head, thorax and scutellum darker, va- 

 riegated with brown ; eyes piceous; abdomen ochreous, 

 the base ferruginous, a broad space on each side black, 

 greenish at the base; elytra with a band next the thorax 

 brown, a large lanceolate spot on the costa towards the 

 apex formed by the brown reticulated nervures and 

 spots between, an oblique paler line near the posterior 

 margin, and a >-shaped one a little beyond the mid- 

 dle ; inferior wings dark fuscous, the nervures darker, 

 paler at the base, with a faint rosy tinge: 1st and 2nd 

 pair of legs with the tips of the thighs and tibiae and a 

 ring near the middle piceous, posterior thighs and base 

 of tibiae fuscous, tarsi tipped with piceous. 

 Obs. — The form of the insect with its wings closed of the 

 natural size is shown towards the foot of the Plate. 



Isstis coleoptratus is found in hedges and woods round Lon- 

 don, in May, June, and July ; I have taken it in Norfolk, and 

 Mr. F. Walker informs me that he often finds it in October 

 on the flowers of the Ivy at Southgate. 



The Plant is lihinanthus Crista-galli (Yellov/ Rattle).
