194 AMERICAN HYMENOPTERA. 



Pubescence as usual. 



Color green, with bluish reflections. 



Type. — University of Kansas. 



Type locality. — Morton Co., Kansas, 3200 ft. 



One specimen, collected by F. H. Snow ; another taken in Kan- 

 sas by the same collector has the blue predominating. 

 Chrysis (Tetrachrysis) kalili n. sp. 



Related to frey gessneri. 



6 mm. — Head. — As in frey-gessneri. Thorax in general punctured like the 

 head. Lateral teeth of metathorax very prominent, acute and practically at 

 right angles to the same. Dorsal aspect of metatliorax in the lower half rather 

 coarsely, irregularly grooved or scooped out. First abdominal segment about as 

 long as the terminal or third abdominal segment, with a shallow channel in the 

 middle of the dorsum. This channel not extending much more than half way 

 toward the apex. On either side of this channel, and in the channel itself, the 

 punctures are distinctly separated from each othej-. The spaces between are one 

 puncture or less in width. Laterally, the punctures become adjoining and give 

 the segment a regular appearance. The second dorsal segment is as long as the 

 combined length of the first and third dorsal segments, punctured throughout, 

 nearly as the first segment near the lateral margin. The lateral margin of this 

 second segment is punctured like the lateral margin of the first segment. Thus 

 the entire second segment has a rugulose appearance, which is, however, not so 

 marked along the middle of the segment as along the lateral margin. 



The third dorsal segment juincturcd like the second dorsal segment, with a 

 series of eleven very distinct, almost circular, deep, separated punctures or pits. 

 These punctures are from less than one of these puncture widths to two of these 

 puncture widths apart. The lateral margin is sinuate, with two troughs and two 

 crests. The first trough one-quarter the distance from the base (one-quarter the 

 length of the lateral margin from the base). The second three-quarters the 

 length of the lateral margin fiom the base. 



The undulations are very gentle and not deviating far from the straight line. 

 Apex nearly as in freygessneri. The external teeth are directed toward the mid- 

 dle line, and distinctly shorter than the middle teeth, which are directed straight 

 back. The emarginations forming these teeth subequal in width. The lateral 

 emarginations forming a segment a little more than a semi-circle. The median 

 emarginations practically forming two sides of an equilateral triangle.

Clirysis (Tetrachrysis) patlonella u. sp. 



Related to pattoni. Median teeth at apex of abdomen as far from 

 each other, or nearly, as from the lateral teeth. 



6 mm. — Basin of face punctured, excepting for a very short distance on either 

 side of the median ridge, which occurs for a short distance along the middle of
