MOSCHEUMA SEBOSUM, 237 



smaller and less numerous near the outermargins and 

 the base (chiefly around the scutellum), densely rugosely 

 strigose along the apical portion of the outermargin and 

 between the apical callus and the suture; each elytron 

 showing two costae , which are directed inwardly up to 

 below the middle and then converge into the apical cal- 

 lus , the latter is strongly developed , the suture rather 

 highly raised posteriorly; the elytra are sensibly narrowed 

 towards the apex, which is rounded, and obtuse at the 

 suture. 



The pygidium is coarsely rugosely striated, strongest 

 above. 



The mesosternal process is rounded below, obtusely 

 pointed above; the breast and the sides of the abdomen 

 covered with deep , large semicircular punctures , the last 

 abdominal segment rugosely punctured ; the anterior tibiae 

 provided with two strong teeth before the terminal fork; 

 the forder coxae and the middle and hinder tibiae clothed 

 with black hairs. 



This species is allied to M. costatum Oliv., but besides 

 by its greasy uppersurface , it differs by its smaller size, 

 longer and less rounded thorax , more strongly narrowed 

 elytra and quite differently shaped mesosternal process. 



Unhappily I do not know its precise locality, but it 

 was captured most probably in Guyana.
