liody bhiLki.-<li-hruwii, jumcturcd, oblong; head with small 

 puucturcs, rather prominent between the antennae, above which 

 it is somewhat indented ; antenna; as long as the thorax or ratht.r 

 longer, brown sericeous; thorax with small i)unctures, anterior 

 and posterior angles dcntilbrm ; disk with a small orbicular in- 

 dentation each side behind the middle, and an irregular one on 

 the basal middle; posterior margin each side of the middle a lit- 

 tle concave ; scutel orbicular; elytra with numerous somewhat 

 large puucturcs j not in stria', with lour slightly elevated lines or 

 nervures, the inner one abbreviated before the tip, the others 

 confluent near the tips. 



Length from two-tifths to three-fifths of an inch. 



This insect approaches, in character, nearer to S<iiul<t/us than 

 to any other genus. In that genus the mandibles arc remarka- 

 lily falcate, and the tooth is on the inner side, towards the base ; 

 they are also covered to the middle by a membrane or coriaceous 

 process ; the tibias are (juadrilateral and denticulate, and the 

 tarsi beneath are clothed with very dense hail's. In our insect 

 the conformation of the antennaj is the same as in the female of 

 S<in(I(i/iis, excepting that they are much more elongated ; the 

 mandibles are less prominent, and have the tooth on the superior 

 side near the tip, which is therefore emarginate, or rather bifid, 

 and are destitute of any membranous covering at base ; the tibia; 

 are not quadrangular, the tarsi are simple beneath, and the nicn- 

 tum is somewhat transversely oval, with a robust dontiiiirm pr.>- 

 ee.ss before. It can be separated under the name of Zrnixi. 



I have found it under the bark of decaying trees,
