sirable to place its characters on record. Its sexual differences 

 seem to consist chiefly in the evenly-rounded front margfin of 

 th-e clypeus, its antennal flabellum a little abbreviated, its 

 ventral segments more massivie and convex, and the hind mar- 

 gin of the apical ventral segment not produced in the middle. 

 The obsolete sinuation of the external margin of the front 

 tibiae is probably due to some accidental cause. As a species 

 it differs from convexicoUis by its non-gibbose pronotum, its 

 iridescent dorsal surface, much more conspicuously geminate 

 striate elytra, etc., and from 7iem oralis by, inter alia, the 

 notably stronger and less close puncturation of its frons pro- 

 notum and elytra. This species and the preceding two are 

 very unsatisfactorily intermediate between Hcitala and Ano- 

 dontonyx, and bear much superficial resemblance to some 

 species of the latter. They differ from both in the nature of 

 their ventral sexual characters, from typical Sritalce by the 

 feebleness of the sexual characters of the antennae, and from 

 Anodontonyx by the flabellum of the antennae being very 

 evidently longer in both sexes.
