rounded and flattened, the sides nearly straight, the base slightly 

 rounded, a conspicuous puncturfl about the middle of the sides, and 

 finely punctured all ovei", the punctures with minute scales as on 

 the head. Elytra as broad as the thorax and broader than long, 

 with about seven extremely fine strife on each, the interstices 

 broad, perfectly flat, and irregularly marked with rows of extremely 

 minute punctures, from which spring short decumbent setigerous 

 scales.

14. Merodontus squalidus. 



Of a dirty black or grey appearance all over, longer than broad. 

 Head transvei-se, two minute tubercles between the eyes, the 

 clypeus very slightly emarginate with three very minute teeth on 

 each side. Thorax a little broader than long, much elevated in 

 front by two ridges rising perpendicularly from the middle of the 

 apex, on each side are two abbreviated ridges, and on the posterior 

 part of the thorax six similar ones : the anterior angles are much 

 enlarged and flattened. The elytra are flat, longer than broad, and 

 about the width of the thoi'ax, the apex at the suture terminates 

 in a squai-e prolongation of each elytron, while the posterior angles 

 are roundly prolonged in a similar degree, leaving four deep narrow 

 emarginations along the apical margin, the lateral edge presents a 

 somewhat scolloped appearance, the disk is furnished with four 

 rows of small velvety-looking tubercles on each, most numerous on 

 the sutural rows, and least so on the lateral row, those on the other 

 two rows are generally larger than the others. The spur on the 

 under side of the posterior thigh is in this species in the middle, 

 and the hind tibiae are less curved than in M. calcaratus. 



Length, 3 lines.
