534 Mr. T. D. A. Cockerell — Descriptions and 



Banhsiella. Apparently Say did not separate tlie two or 

 three allied species of the pura type, and as he doubtless 

 included the insect which Kobertson calls pura, this appli- 

 cation of the name may be allowed to stand. 



Augochlora aztecula, sp. n. 



? . — Belongs to group Oxystoglossi, with the hind spur not 

 pectinate. Length about 7 mm. ; anterior wing about 5. 



Golden green, middle of second abdominal segment stained 

 with coppery red ; mandibles ferruginous, darker at base 

 and apex ; tubercle of labrum simple, truncate ; face broad, 

 orbits very strongly emarginate, and strongly converging 

 below ; clypeus with strong rather close punctures, and its 

 anterior edge broadly black; flagellum dull ferruginous 

 beneath ; mesothorax and scutellum brilliantly coloured, 

 appearing granular from extremely minute and close punc- 

 tures ; hind part of scutellum with some fuscous hairs ; area 

 of metathorax with fine longitudinal ridges, except the 

 middle subapical part, which has finer transverse strias ; 

 tegulse ferruginous with pallid margins. Wings dusky, 

 somewhat reddish ; stigma and nervures testaceous ; first 

 r. n. meeting second t.-c. Legs black, with the knees, the 

 tarsi, and the anterior tibice (except a cloud behind) ferrugi- 

 nous, the anterior femora green beneath. Abdomen with the 

 hind margins of the first two segments more or less piceous, 

 though very narrowly ; no marginal vibrissse, but the lower 

 edge of the dark base of the second and third segments, 

 which slides under the segment before, is very finely and 

 regularly ciliate ; venter piceous, with a subapical ferruginous 

 stain^ The ventral surface of the abdomen, as well as the 

 hind legs, carries much pale yellow pollen. 



In my table in ' Canadian Entomologist,' 1897, p. 4, this 

 runs nearest to A. lahrosa^ Say, and A. aurifera, Ckll., but 

 it is readily separable ' from both by the colour of the legs. 

 In Scbrottky's table of Brazilian species it runs near 

 A. urania, Sm., but that is smaller, with a blue-green 

 abdomen.

Augochlora cordi'cefioris, sp. n. 



5 . — Belongs to Oxystoglossi, but with stature of a Ghlora- 

 lictus ; length about 6 mm. 



Head and thorax brilliant green ; abdomen with the first
