longer and less transverse ihaii that of piinefitlatasj Fiilirs., 

 and others ; the prosternuin, the anterior lobe is markedly 

 marginate, the lateral striae are almost parallel^, very slightly 

 diverging anteriorly, keel and lobe rather coarsely, not closely 

 punctate, with a line of punctures along the strice j the nitso- 

 sternum is also markedly marginate, and the surface and that 

 of the metasternum sparingly punetulate ; the anterior tibia3 

 are 7— 8-denTiculate. 



This species is narrower (less robust) than jmnctulatus, 

 Fiilirs., and the other chief distinguishing characters are the 

 more strongly bordered anterior margin of the prosternun^i, 

 and its striai are more paiallel, scarcely diverging anteriorly, 

 and the punctures of the meso- and metasterna are larger.

This genus is founded to receive a single species from 

 Madagascar which suj)eificially somewhat resembles j\l(icro- 

 sternus, but the body is less depressed, and the other characters 

 which will not peimit its inclusion in it are: the pygidium 

 is convex, the prosternal keel is wide ami truncate at both 

 ends, the mesosternum is very broad and nearly straight (not 

 sinuous) anteriorly, the anterior tibiaj are outwardly denti- 

 culate, tarsal groove not sinuous, and the tarsi are pilose 

 beneath. The form of the forehead (without striae) and the 

 form of the thorax are very siu)ilar to those o'i Macrosternus ; 

 the dorsal sutural stria is bent like that of the American 

 Ulster curvatus, Er., but this being a character of many 

 African species of Ulster, it cannot be considered an 

 important one.
