 nearest eye margin ; a distinct line-like furrow above and below middle 

 ocellus; facial basin smooth, shining; clypeus rounded anteriorly, 

 slightly notched in middle, without teeth; 'no middle carina on civ 

 peus; distance between the eyes at the clypeus about equal to width 

 of clypeus in the middle; antennae simple, flagellum (excluding pedi- 

 cellum) a little more than twice as long as scape, first joint of flagel- 

 lum a little longer than second; pronotum not ridged anteriorly, a 

 small blunt tooth laterally, on anterior face finely punctured ; dor- 

 sulum finely densely punctured; on the anterior portion there are 

 some large punctures with many fine ones in between; meso-pleurae 

 very finely striato-punctate; no furrow between the epimeron meso- 

 pleuralis and mesosternum, but there is a small circular fovea in about 

 middle ; scutellum with irregular large punctures ; dorsulum of meta-

 and posterior face irregularly transversely striate ; middle furrow dis-

 nearer the middle than apex of cell; anterior trochantcrs triangular, 

 not quite half as long as their femora ; tibial shields a little longer 

 than broad, anterior and posterior angle rounded; medial tarsi very 

 slightly flattened, the first joint equal to the following joints united; 

 abdomen shining, apparently not sculptured. Color black, including 

 mandibles; scape except a spot at base within, clypeus more or less,

Closely related to C. vcrnalis Pack., but easily known by the 

 color of the shield, the presence of a circular fovea on meso- 

 pleune, the shorter first joint of flagellum, and other characters.
