The above characters are drawn from insects receding still farther 

 from the true type of this family than the Aderus, more especially in 

 the singular structure of the eyes and antennae 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 

 that a 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. Cerambyx pygmeus, De Geer, f Anthicus pygmcEus, Gyl- 

 lenhal) ; the female of which, according to the latter author, is the JVb- 

 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. Mzrsh^nn^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 postice transversim impresso.
