66 MESODERES. 



elytrorum paullo superantibus ; metatarso postico articulis 

 duobus sequentibus unitis longitudine siibaequali , articulo 

 unguifero gracili. 



Prosternum antecoxale medio subimpressum ^ antice utrin- 

 que subcallosum ; prosternum postcoxale foveolatum. Meta- 

 sternum late impressum in mare ^ sulcatum in f e min a ; 

 abdominis segmenta basalia valde abbreviata , coalescentia , 

 suturae vestigio in medio nullo vel obsoleto ; segmento apicali 

 foveolato in mare , laevi in femina, 



The body is unusually short in comparison with its 

 broadness and much convex ; the head is strongly trans- 

 verse and almost dilated sideways; the greater transverse 

 diameter of the prothorax passes through the middle of 

 the longitudinal one , the excavation or compression at the 

 sides anteriorly is wanting, the legs are comparatively 

 more elongate. 



I consider this interesting Brenthid as a Zemiosiue-like 

 genus with the body conspicuously shortened and convex 

 and with some peculiar characters that may ultimately 

 require a new group for its reception.
