truncate at base ; abdomen with the penultimate segment longest; 

 tibiaj spinous, a little arquated.

In the present state of the science, the latipcs can no longer 

 remain in the genus Ox^tehis, as a species of which Gravenhorst 

 described it. That author was, however, perfectly sensible of 

 its distinguishing characters, and had he written twenty years 

 later, I should not now have to construct this new genus. The 

 following are his remarks adjoined to his copious description, to 

 which I must refer the reader : 



" Cum hoc insectum palpisinstructum sit filiformibus, autennis 

 extrorsum crassioribus, thorace immarginato basi truncato, Tachi- 

 nis adnumerandum foret, si solos characteres artificiales (Coleopt. 

 Micropt., p. 134) datos respicercmus. Habitu autem toto, et ex- 

 ceptis ultimis palporum articulis, partibus etiam singulis cum 

 Oxytelis hujus familise plane congruit. Certo systematis natu- 

 ralis nuUam haberemus rationem, cum hoc micropteron Tachinis 

 adjungeremus. C)xytelis autem, sicut hue usque determiuati 

 erant, ob characteres per systema artificiale constitutes, baud 

 adsociari potest. Eodem ergo jure, quo Astrapaei genus olim a 

 Staphylino disjungebatur, quibus attamen simillinium est, hoc 

 etiam insectum genus novum, ab Oxytelis separatum, conderet, 

 nisi regula systematis naturalis, i. e. character totus externus 

 seu habitus totus, dissuaderet." [463]
