This and the next are the largest of our species ; they are both 
common in woods, on birch, hazel, oak, &c., and are easily confounded. 
I. onixtus is a trifle smaller and narrower than atomarius, its hemelytra 
are much more darkened with transverse streaks, and present several 
distinct hyaline spots. In atomarius they are uniformly pale brown, 
with obscure, short, fuscous, transverse striae ; and the fore-thighs have 
only one black ring, or sometimes half a ring, near the apex.

Common in the London District ; Surbiton ; Birch "Wood, &c. It 
nearly resembles I. pleheius, Fall, (according to that author), which, 
however, difiers in the straight suture of the hemelytra, and is therefore 
an AtJiysanus : it is given in catalogues as British, but I have never 
captured a specimen, and those commonly named plebeius in collections 
are /. mixtus. Fab.

This species can hardly be mistaken, being dusted all over with 
blood-red specks. It must be rare in this country ; I have only seen 
one specimen, which is in the collection of Mr. Douglas.
