AttT. 8. BEES FROM VICTORIA, MEXICO COCKERELL,. 5 



based on a female from Mexico in the Paris Museum. Vachal's 

 species has never been fully described, but I can only presume that 

 our insect is identical. 



AUGOCHLORA (OXYSTOGLOSSA) DIMISSA, new species. 



Female. — Extremely similar to A. inetallica (Fabricius), bright 

 green with the hind margins of the abdominal segments narrowly 

 black; but easily separated by the area of metathorax, which is 

 large, fully as long as the scutellum, evenly rounded (instead of 

 angulate) posteriorly, and covered, nearly to the margin, with very 

 fine radiating striae, except in the middle, where it is minutely ru- 

 gosopunctate. The abdomen is not so shining as in metallica., and 

 the mandibles are reddened subapically. The legs are black, with 

 the anterior femora behind, and the middle and hind coxae green. 

 The fifth abdominal segment is green basally, not all black as in 

 jyietallica. The scutellum is as densely (partly confluently) punc- 

 tured as possible, the punctures not of two sizes. The pubescence of 

 the legs is pale, not black as in A. feronia Smith. The supraclypeal 

 area is microscopically roughened and has sparse punctures. The 

 hind spur of hind tibia is microscopically serrulate. The punctures 

 of the abdomen are very small, and not dense. The wings are 6 mm. 

 long, moderately dusky. Scutellum and postscutellum with fulvous 

 hair. 



Victoria, Mexico, March 16, one female. 



This is a northern representative of the South American group of 

 A. metdUica (Fabricius), A. iheriiigi Cocke rell, -4. caerulior Cock- 

 erel!, etc.
