Hind margins of abdominal segments narrowly or not black, yellowish- 

 green species 6. 



Augochlora Robertsoni^ n. sp. 



This species had apparently been confounded with pura, but Mr. 

 Robertson, who takes it commonly in Illinois, has pointed out good dis- 

 tinctive characters in Tr. Am. Ent. Soc, XX. (1893), p. 146, under the 

 ri3.mt oi /abrosa,'$>3L.y. I possess a 9 specimen from S. Illinois, sent by 

 Mr. Robertson, and accepting his identification of it, had placed labrosa 

 in my table of Mexican Augochlora, from the characters it presented. Say 

 described his labrosa from Mexico, however, and suspecting later an 

 error in identification, I compared Say's description. The result is, that 

 I am convinced that Say did not have Mr. Robertson's Illinois insect 

 before him, and that the latter stands in need of a name, being apparently 

 different from other described North American species. It is accordingly 

 named after the writer who first pointed out its characters, which are, 

 principally, the evenly punctured, not roughened, mesothorax, the broad 

 face and deep emargination of the eyes, in the female ; and the fourth 

 ventral segment not broadly emarginate in the male. The stigma and 

 nervures are brown, not very dark, the second submarginal cell is con- 

 spicuously longer (squarer) than in pura ; the legs are very dark brown, 

 the front femora metallic behind. In most respects, the insect is like 

 pura, and could easily be confused with it. 



Say's type of labrosa is said to be a $ , while the allied Bhighami is 

 described from a ^ , but I do not think they can be the sexes of one 

 species. 



Augochlora Townseiidi, n. sp. — $ . Length, 10 mm.; head and thorax 

 densely and confluently punctured, brilliant blue-green, pleura becoming 

 very strongly tinted with blue ; but the face, especially the clypeus and 

 supraclypeal area, yellowish-green, the latter with a coppery tint. Abdo- 

 men dark blue-green, not so blue as the thorax ; hind margin of first 

 segment narrowly, and of the others broadly, black ; venter black, none 

 of the segments emarginate, nor any trace of the fish-tail brush of Bing- 

 hatni. Face broad, emargination of eyes deep; clypeus shining, sub- 

 cancellate with large punctures, its anterior edge very narrowly at sides, 

 and the labrum, black ; labrum striate, mandibles dark, only very faintly 

 rufescent about the middle ; antennae reaching to scutellum, black, feebly 

 rufescent beneath, not at all hooked at tip, first two joints of flagelluni
