From A. notophos the Guayaquil bees differ as follows: mandibles red, 

 with a green basal spot; third antcnnal joint dull ferruginous; disc of meso- 

 thorax more closely punctured, green or golden-green, with no dark area ; 

 scutellum with golden tints ; area of metathorax conspicuously angulate be- 

 hind ; tarsi ferruginous. 



If my suspicion that typical notophos is dizrrsipcnnis proves 

 correct, the present insect will stand as a distinct species, A. (Au- 

 gochlorops'is) nothns Ckll. 



Augochlora matucanensis new species. 



Female. — Length about 7 mm., anterior wing 6 ; brilliant yellowish-green, 

 front and sides of face more blue green, contrasting with the golden-green 

 clypeus and supraclypeal area; pubescence scanty, very pale brownish; head 

 very large; clypeus strongly, not very densely, punctured, the lower margin 

 black ; mandibles black with a small green basal spot and the apex broadly 

 dark red ; labrum broad, not bidentate or emarginate ; flagellum dusky testa- 

 ceous beneath ; ocelli small, close together ; eyes deeply emarginate ; front 

 and vertex minutely, densely, granular-punctate ; occipital margin with a sharp 

 border ; vertex and cheeks very large ; checks obtusely angular below and 

 behind ; distance from top of eye to occipital margin nearly as great as to 

 antenna ; angles of prothorax well-marked ; mesothorax and scutellum bril- 

 liantly shining, with extremely fine punctures, close even on posterior middle 

 of mesothorax ; pleura closely punctured ; area of metathorax not defined, 

 marked by fine oblique strise, some of which become transverse in the middle, 

 but the apical part is broadly smooth and shining, with no sharp or distinct 

 rim; tegulae rufopiceous; wings reddish dusky, stigma and nervures dull pale 

 reddish ; first r. n. entering basal corner of third s. m. or meeting second t. c. ; 

 legs piceous, with pale hair, anterior femora green beneath ; hind spur simple ; 

 abdomen shining yellowish-green, very finely punctured, hind margins of seg- 

 ments not darkened or vibrissate. 



Habitat. — Matucana, Peru (type locality), 4 females, June-July, 

 1913, 7,300 ft. (Bnies). 



Also one from foothills near Lima, Peru, at flowers of Helio- 

 tropimn, Dec. 5 (C. H. T. Townsend). In Vachal's table (Misc. 

 Ent.) this runs out at 61 (p. 48). I cannot identify it with any species 

 described from Peru, Brazil, etc. It is readily known by the shape of 

 the head and the sculpture of the metathorax, but the head varies 

 in size. 



The above species of Augochlora may be readily separated as 

 follows :
