It has already been thought necessary to separate several insects from 

 the extensive genus J^otoxus, established by Geoffrey and Olivier, fAn- 

 thicus, Payk., Fabr., Gyll, &c., Cucullus, Latr., Regne Animal), and ac- 

 cordingly the name of .^nthicus has been generically restricted to those 

 species which in form resemble the true Notoxi (N'ot. Monoceros, &c.) 

 but do not possess the cornuted thorax of those species. Jlnthicus po- 

 pulneus (figured by Panzer) has been formed into the geniis Xylophilus, 

 and Latreille (Fam. Nat. 383.) observes that it has the appearance of 

 the BruchideB, having the posterior thighs incrassated, the second joint 

 of the antennae small, the third long and thickened at the tip, and the 

 remainder shorter than the preceding, and thick. In the R^gne Animal 

 another genus, S<erojoes,f is established in the family, in which the an- 

 tennae 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.

Caput transversum, inflexum, thorace latius, postice in coUuni 

 non productum, oculis magnis prominulis lateralibus. 



* My reasons for forming the family name from Notoxus, are stated in the 

 fourth volume of this work, p. 4. 



t Had Latreille forgotten that at p. 240 there is also a genus Sterope ?
