In 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 con- 

 cave, receiving the prosternum. The epipleurte 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 deficxed than in any of the other genera, of the sub-tribe. 



The species resemble each other closely in outline, differing in the form of the men- 

 tum and front. All are winged. They may he known by the following characters : 



Third joint of antenna; longer than fourth, twice as long as second. 



Femora rufous, tibia 1 black; surface opaque. 



Legs entirely black ; surface shining. 

 Third joint of antenna: short. 



Legs black; surface opaque.

Iii. this species the mentum has the anterior angles prominent. The front is heini- 

 hexagonal, with the angles rounded. The eyes are scarcely einarginate by the sides of 

 the front, and are rather more prominent than in the two succeeding species. The thorax 

 is nearly square, slightly einarginate in front with prominent angles, sides nearly parallel, 

 base strongly Insinuate with prominent angles. The lateral margin is acute, but not com- 

 pressed. The elytra, are opaque, with eight entire rows of elongate deeply impressed 

 punctures, and one short scutellar row. 



Length .30-44 inch. 



Occurs abundantly in the Middle and Eastern States, under bark, etc.

The reference of this species 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, tin- hind tarsi are rather long and slender and 

 the body depressed, while in this tin- form is robust. It differs from the other species of 

 the present, genus, 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 emarginate, and the angles very prominent 

 and acute. The hind tarsi are short, the first joint scarcely equalling the second and 

 third together, while the last joint is equal to the first three. As in the other species, the
