NORTH AMERICAN HYMENOPTERA. 235 



middle, and conspicuously biarcuate; anal margin quadridentate, the robust teeth 

 prolonged, acutely triangular subequal, emargination arcuate, equal; wings 

 slightly sordid, perfectly hyaline on the limb. Length 7 mm. Texas." 



Varies from 7-8.5 rum. The color is emerald-green with some blue 

 reflections ; basin of face very finely and narrowly striate. Gribodo is 

 hardly correct and a little difficult to understand when he says : " ante- 

 apical series entirely wanting," but farther on he explains, " forming in 

 the same position a very large and deep erose fovea," which means in the 

 same position as the anteapical series of pits. This fovea, which being 

 " interrupted in the middle," forming two, is nothing more than the two 

 median pits greatly enlarged, becoming confluent with the others and 

 disturbing the evenness of the posterior margin of basal area of seg- 

 ment, causing it to be arched. The size of these large pits, however, 

 varies, and in one specimen hardly cuts the before mentioned margin. 

 The apical teeth also vary in length. 



Chrysis liirKiitR n. sp. — One specimen deep blue with dull purple reflec- 

 tions, the other green and blue with black and dull purple on the dorsum of the 

 second abdominal segment; head, thorax and abdomen densely and equally punc- 

 tured ; in one specimen the punctures on the dorsum of the second segment be- 

 coming largely confluent, or running together in rows; basin of face finely punc- 

 tured on each side (best seen in certain directions and light) with long coarse 

 white hairs; pits very large and confluent in a rather deep groove, which ends 

 midway on the lateral margin; teeth unusually long and slender and much 

 turned down ; wings clear hyaline ; 4.5-6 mm. 'J, 9- 

 Montana and Utah ; two specimens. 



Chrysis pelliicidula n. sp. — Green and blue, deep purple and black on 

 the dorsum of the second abdominal segment and a little deeper blue on the first 

 segment; basin of face punctured; head and thorax densely and equally punc- 

 tured ; abdomen with the punctures separated, especially so in the second segment, 

 closer and a little confluent on the sides of the third segment: pits very large, 

 confluent, luteous and when held towards the light somewhat transparent ; the 

 median separation very narrow; apical margin abrupt, sharp; teeth coming to 

 sharp points; wings hyaline, very slightly infumated ; 5.5 mm. 9- 

 Virginia ; one specimen. 



Chrysis Pstttoni n. sp. — Emerald-green with blue reflections; basin of 

 face punctured ; head and thorax with the punctures rather fine, dense and equally 

 distributed ; abdominal punctures hardly separated, about equal, close and a little 

 confluent on the third segment; pits medium, rather indistinct, dark colored, the 

 groove moderate, ending near the base of segment, a little raised above the pits on 

 its anterior border at the extreme dorsum; apical margin not very abrupt; ^\ings 

 rather strongly infumated nearly to the apex ; 6 mm. 9 • 



Colorado ; one specimen. The figure gives only the lateral view of 

 third segment ; as seen from above it exactly resembles fig. 64, same 

 , plate.
