M0N0C4RAPH OF THE NORTH AMERICAN PROCTOTRYPIDvE. 361 



The 9 of this species was received fioni Mr. T. D. A. Cockcrell, from 

 Colorado, but I liave no doubt it is properly correlated with a 6 taken 

 iu Virginia, as it agrees in venation and general appearance, although 

 the color of the abdomen is slightly different.

9. Length, 2.5'"'". Polished black, shining, pubescent; anteunfe 

 fuscous, the first two joints honey-yellow; legs honey-yellow. An- 

 tennae 15-jointed, filiform, reaching to the middle of the abdomen; 

 scape more than twice as long as the first fiagellar joint; first and 

 second flagellar joints equal, 3 times as long as the pedicel; the follow- 

 ing joints to eighth gradually shortening; from here to the last much 

 shorter, the thirteenth and fourteenth being only a little longer than 

 thick, equal, and shorter than the last which is conic. Wings hyaline, 

 the marginal cell only twice the length of the marginal vein, the venation 

 fuscous. Abdomen one-third longer than the head and thorax to- 

 gether, the x^etiole being more than twice as long as the metathorax, 

 fluted; the body of abdomen is smooth, shining, covered with sparse 

 white hairs along the sides, at tij) and beneath, the first segment occu- 

 pying nearly the whole surface, with a longitudinal sulcus at base; the 

 second is very short, but twice the length of the third; the last conic, 

 piceous.

9. Length, 2.8""'. Polished black, pubescent; scape, pedicel, and 

 legs honey-yellow; rest of antennte subfuscous. Head transverse, 

 wider than the thorax, Antennte IS-jointed, filiform; the scape fully 

 4 times as long as the first flagellar joint, obclavate, first and second 

 flagellar joints equal, twice as long as the pedicel or a little more than 

 3 times as long as thick, the following joints very gradually sub- 

 equal, the last conical, one-third longer than the penultimate. Wings 

 hyaline, pubescent, the marginal cell about 3 times as long as the 

 marginal vein. Abdomen conic-ovate, black, polished, the petiole 

 opa(|ue, fluted, nearly twi<'e the length of the metanotnm, the third 

 segment short but about twice the length of the fourth. 



Habitat.— Arhngton, Va. 



Type in Coll. Ashmead. 



Allied to C. mellij)cs Say, but differs iu the relative length of the 

 autennal joints and in having a longer marginal cell.
