368 REVISION OF THE TKNEBRIONIOjE OF AMERICA, 



Above each eye in this insect is a rather small tubercle, similar to that seen in our 

 species of Qlosonia .. The frontal suture is also similarly impressed and the epistoma 

 convex. One specimen is known, of similar derivation as that of the preceding »vmis. 



\| angustus, brownish ferruginous, moderately shining, elongate oval, parallel. Head rathei coarsely bui 

 sparselj punctured. Thorax --li^lit 1 \ broader than long, feebly convex, coarselj bui sparse!) and irregularly punc- 

 tured; apex emarginate, angles uot prominent; base bisinuate, angles rectangular; sides anteriorly rounded, posterior 

 three-fourths straight and parallel, finely margined, margin slight!) reflexed. Elytra elongate, parallel, apex obtuse, 

 base emarginate at middle, with eight striae of elongate punctures, one marginal and a very indistinct scutellar stria; 

 interstices flat, finely and sparsely punctured. Propleurse coarsely but sparsely punctured, pectus and abdomen finely 

 and sparsely punctured, Bmooth and shining.

The male is narrower but smaller than the female, and the frontal tubercles distinct. 

 though less prominent than in the preceding species. The base of the thorax has also a 

 distinct impression on each side, scarcely evident in the female. This species .differs from 

 the preceding in its more elongate and less depressed form, its color and the form of the 

 thorax. In pia m the thorax gradually narrows from base to apex, in angustus the thorax 

 is rounded only in front, while the posterior three-fourths are straight and parallel,

In addition to the characters given in the synoptic table, the following will serve to 

 render this genus more certain of recognition, when all the foreign genera of the tribe are 

 taken into consideration. 



Epistoma truncate in front, convex at middle, slightly concave on the sides, suture in- 

 distinct. Eyes \ei\ deepl) emarginate in front, superior portion elongate, oblique. An- 

 tennae short, rather robust ; first and second joints thicker than the third; second short. 

 nearly globular ; third slightly longer than fourth; joints four to eleven verj gradually 

 broader, last joint larger and truncate at tip. The hind taisi are short, first joint equal 

 to the two intermediate, and last joint slightly longer than the first. Intercoxal process 

 rounded at tip.

The head and thorax are coarsely, the latter rather densely punctured. The elytra 

 are sculptured with rows of faintly impressed punctures, the interstices of which are flat 

 except at middle, when they form a moderately elevated tine line.
