ON THE MEXICAN BEES OF THE GENUS AUGOCHLORA. 



BY T. D. A. COCK.ERELL, MESILLA, N. M. 



The Mexican species of this beautiful genus may be readily separated 

 by the following table : — 



A. Hind spur of hind tibia minutely ciliate or simple. = augochlora, s. str. 



1. Entirely copper colour, with tints of carmine .flammea, Sm. 



2. Head and thorax dark indigo blue, abdomen black with some green 



reflections nigrocyanea, Ckll. 



3. Head and thorax green 4- 



4. Abdomen black, size small setninigra, Ckll. 



Abdomen crimson ignita, Sm. 



Abdomen green, without hair-bands 5- 



5. Hind margins of abdominal segments broadly black ; large blue- 



green species, with fuscous nervures Bitighami, n. sp. $ . 



Hind margins of abdominal segments narrowly or not black; smaller, 

 more yellowish-green species 6. 



6. Small, wings dusky, nervures fuscous aurifera, n. sp. 



Medium size, nervures dull testaceous 7. 



7. Face broad, emargination of eyes deep .... labrosa, Say. 



Face narrow, emargination of eyes shallow pura, Say. 



B. Hind spur of hind tibia pectinate. = augochloropsis, 



subg. nov (type, sulngnita). 



1. Head and thorax black, abdomen ferruginous aspasia, Sm. 



Head and thorax green 2 . 



2. Abdomen crimson subignita, Ckll. 



Abdomen brassy, with dense short fulvous pubescence beyond 



basal segment ^ aurora, Sm. 



Abdomen green, of the same colour as head and thorax, with two 

 narrow bands of yellow pubescence splendida, Sm. 



C. Hind spur of hind tibia not yet described. 



1. Bright green, agreeing only with splendida in having abdominal 



hair-bands, but these are white viridana, Sm. 



2. Small piceous species ; margin of mesothorax, postscutellum, most 



of enclosure of metathorax, and bases of second and third abdomi- 

 nal segments shining green tisiphone, Gribodo. 



A. labrosa is cited from Mexico by its describer, but I have not seen 

 it from that country. Mr. Robertson sends it to me from Illinois. There 

 are two species found in Texas, which may be expected also across the
