 dusky at base; mandibles piceous with black tips. Head minutely punctate. 

 Thorax closely minutely punctate, sericeous. Face with a median ridge and a 

 few striae converging towards base of mandibles; parapsidal furrows delicate but 

 distinct; deeper, broader and more sharply defined posteriorly; mesojtleura for 

 most part smooth and polished, but along the base hairy and delicately striated ; 

 metapleura hairy. The scutellum projects slightly over the metathorax, rugose, 

 the metathorax short, abruptly declining, with two distinct parallel carinse on 

 the disc and on each side a long transverse fovea. The abdomen is black, pol- 

 ished, not longer than broad vertically and pubescent at base of second segment, 

 the delicate connected suture distinguished with difficulty, and only visible when 

 examined with the lens carefully from the side; the sheaths of the ovijjositor 

 project about 0.6 mm. above the dorsal surface; the third, fourth and fifth seg- 

 ments are exceedingly short; the fifth and sixth segments and the ventral valve 

 are brown, or yellowish brown, and, if examined carefully, exhibit a fine, deli- 

 cate punctuation. Wings hj^aline, pubescent; the veins pale yellowish; in one 

 specimen the cubital cell is not defined, and the areolet is without the inner side 

 vein ; the other specimens have the cultital cell and the areolet distinct.

 dricnx ostemiackenu Bass. Received by Dr. C. V. Riley from J. G.

This species a})proaches nearer to C. ficm Fitch, but is at once 

 distin<rnished by the different colored head and thorax, the delicately 

 marked parap.sidal furrows and the rufous abdomen.
