Chrosis. 



Sharp: Ann. Mag. Nat. Hist., May, 1877. 



The species described below exhibit the following characters : 

 Clypeus short, quite unfolded and extended, so that the forehead is 

 not limited at all from the clypeus in the middle, and the large labrum 

 is almost on the same level as the forehead ; antennal spaces very indis- 

 tinct and very widely separated from one another. Antenna with the 

 second and third joints elongate. Prosternal process broad and stout, 

 not curved upwards behind the coxae. Mesosternal cavity with strongly 

 elevated borders ; these attain the intercoxal suture, and their hinder 

 portions are quite horizontal. Coxal plate with trochanteral portion a 

 good deal longer than the femoral portion, the long portion occupying 

 about half the whole width, and thence gradually narrowed till it meets 

 the episternum. Tarsi with all the joints simple and well developed, 

 the fourth, however, a good deal shorter than the third.

 elongata, angusta, nitida, nigra, parcissime pubescens, pedibus piceis ; 

 thorace pernitido, elongate, quam latiore multo longiore, parce punctato; 

 elytris profunde striatis, striis fortiter punctatis, interstitiis fere laevis, 

 apicibus haud prolongatis, subrotundatis ; prostemi lateribus dense 

 punctatis ; lamina coxali angusta, margine interne nullo modo sinuato ; 

 tarsis elongatis, gracilibus, subtus haud dense pubescentibus.
