The above characters are drawn from insects receding still farther 
from the true type of this family than the Jderus, more especially in 
the singular structure of the eyes and antenne which vary in the 
sexes; in fact, the peculiar formation of the latter organs gives the 
males of these insects, when magnified, somewhat the appearance of Calo- 
pus serraticornis, between which and Euglenes, it is, indeed, probable 
thata nearer than analogical resemblance may exist. 
Gyllenhal gives the two following species, (which from the similarity 
in formation are referable to the same subgenus,) although it may per- 
haps be doubted whether, as that author has indeed surmised, they may 
not eventually prove identical. 
Species 1. Cerambya pygmeus, De Geer, (Anthicus pygmeus, Gyl- 
lenhal); the female of which, according to the latter author, is the Vo- 
toxus melanocephalus of Panzer. 
Species 2. Anthicus oculatus, Paykull, the female of which is without 
a doubt the Lytta nigricollis of Marsham, a name which must sink into a 
synonym, Paykull’s name having the priority. Marsham’s Lytta nigricollis 
was, I believe, unique as British in Mr. Kirby’s cabinet until last July, 
when numerous specimens of both sexes were beaten out of a whitethorn 
bush at Windsor, by Messrs, Griesbach and Waterhouse; thereby 
confirming the correctness of Gyllenhal’s views as to the identity of the 
sexes, and also that the female is the Lytta nigricollis of Marsham; its 
specific character, which is applicable to both sexes, is 
Euglenes oculatus, Eugl. niger punctatissimus, tenuiter pubescens, 
antennis pedibus elytrisque testaceo-fuscis, his interdum ad apicem obscu- 
rioribus; thorace posticé transyersim impresso,
