[n this genus the mentum is trapezoidal, narrower behind, convex along the median 

 line, truncate in front, with the angles prominent or rounded; inserted upon a narrow 

 peduncle. The prosternum is slightly prolonged in all the species, the mesosternum i 



, receiving the presternum. The epi pleurae extend beyond the last ventral suture, 

 but not to the tip of the elytra. The femora are slender and the tarsi short The head is 

 always more strongly deflexed than in any of the other genera of the sub-tribe. 



The species n s mble e ich oth r closely in outline, differing in the form of the n

In this species the mentum has the anterior angles prominent. The front is hemi- 

 bexagonal, with the angles rounded. The eyes are scarcely emarginate by the side- ,,r 

 the front, and are rather more prominent than in the two succeedii a s. The thi 



is nearly square, slightly emai'ginate in front with prominent angles, sides nearly parallel.

 punctures, and one short scutellar row.

The r< ference of this sp ,cies to the present genus is made not without some misgiv- 

 ings that it should in all probability constitute a new one. It cannot in my opinion re- 

 main associated with Metaclisa, in which the hind tarsi are rather long and slender and 

 the bodj depressed, while in this the form is robust. It differs from the other species ol 

 the present ire eis. in having the mentum rather more convex along the median line and 

 the middle lobe more prominent. The lateral lobes are also more prominent, and the 

 mentum thus resembles that of Metaclisa. The front is also more broadly rounded. The 

 mesosternum is more prominent, more deeply craarginat ■. and the angles very prominent 

 and acute. The hind tarsi are short, the first joint ° I - md and 

 third together, while the last joint is equal to the first three \- in tl th< r species, the
