NORTH AMERICAN HYMENOPTERA. 241 



CJhrysis intricata Brulle. Nat. Hist, des Ins. Hym. iv, 25, 1846. 

 Seven specimens in the collection ; from the localities Iowa, Georgia, 

 Texas, Arizona, California and Dakota. From deep blue with very 

 slight green reflections to dark green with blue and bright green reflec- 

 tions. Basin of face punctured, in some specimens with a narrow 

 smooth space in the extreme centre. Head and thorax densely punc- 

 tured, the punctures here and there confluent. Abdomen punctured 

 rather closely, except on the first segment and the sides of the second, 

 where the punctures are larger and separated. In one specimen the 

 punctures are uniformly close and equal over the entire surface of the 

 abdomen, in another they are larger on the extreme base of the first seg- 

 ment, but close. In a greater number of the specimens there is a patch 

 of close, finer punctures on each side of the dorsum of the first segment. 

 Pits medium, distinct, or subconfluent in certain specimens. Posterior 

 margin of anterior area of third segment not swelled, but sometimes a 

 little advanced, or sublobed in the middle. The groove not deep, but 

 distinct, ending on the lateral margin quite near the base of segment, 

 one specimen with tlie pits semi-transparent, luteous, the same color 

 spreading upon the apical portion of the lateral margin and coloring 

 slightly the apical margin. There is little variation in the position of 

 the apical teeth ; some specimens have the outer teeth blunt, less pro- 

 duced. Wings in one specimen clear hyaline, in the others infuscated or 

 infumated ; 8-9.5 mm. S $ .

One specimen from Georgia. I am almost sure about the determina- 

 tion from Brulle. I have supposed it to be the Fabrician species. It is 

 difiicult to determine whether Dahlbom describes the same species or not. 

 The punctures of the head and thorax are large, very dense, but only 

 here and there confluent. Basin of face punctured. The abdominal 

 punctures are largest and separated on the first segment, and together 

 with the punctures on the sides of the second have finer punctures be- 

 tween them. A patch on each side of the dorsum of first segment 

 closely and finely punctured ; the entire dorsum of the second segment 

 and all of the third with rather close, small, equal punctures. Pits nu- 

 merous, small, round, distinct, seemingly deep, contained in an e(jual 

 shallow groove, ending on each side near the base of segment. The 

 apical teeth are about equal in position, the median ones largest, and the 

 emarginations between them deepest ; the second pair are more acutely 

 pointed, the emarginations rounded ; the outer teeth scarcely deserve the
