Coleopterous Insects, with Characters of two new British

Ir has already been thought necessary to separate several insects from 
the extensive genus Votorus, established by Geoffroy and Olivier, /_An- 
thicus, Payk., Fabr., Gyll, &c., Cucullus, Latr., Régne Animal), and ac- 
cordingly the name of Anthicus has been generically restricted to those 
species which in form resemble the true Notoxt (Not. Monoceros, &c.) 
but do not possess the cornuted thorax of those species. Anthicus po- 
pulneus (figured by Panzer) has been formed into the genus Xylophilus, 
and Latreille (Fam. Nat. 383.) observes that it has the appearance of 
the Bruchide, having the posterior thighs incrassated, the second joint 
of the antenne small, the third long and thickened at the tip, and the 
remainder shorter than the preceding, and thick. In the Régne Animal 
another genus, Steropes,t is established in the family, in which the an- 
tenn terminate in three very long joints. In addition to these I have 
thought it expedient to propose the two others characterized below, founded 
upon species varying very considerably in form and characters from the 
other groups.

* My reasons for forming the family name from Notowus, are stated in the 
fourth volume of this work, p.4.
