Dec, 1914-] Cockerell: Bees From Ecuador and Peru. 325 



(except rufous apex) and labrum pale yellow; lower part of cheeks (beneath) 

 shining golden-green, with slight coppery tints ; antennae long, black basally ; 

 flagellum pale testaceous beneath except at extreme base; fourth antennal 

 joint broader than long; lateral angles of prothorax not very prominent; 

 mesothorax moderately shining, minutely sculptured ; scutellum more shining ; 

 area of metathorax large, at least as long as scutellum, rough, with indistinct 

 oblique striae; tegulae rufotestaceous ; wings dusky hyaline, stigma (which is 

 large) and nervures red-brown ; second s. m. extremely small and narrow, first 

 r. n. meeting second t. c. ; femora yellowish-green ; knees and ends of tibiae 

 clear ferruginous, but greater part of tibiae fuscous ; tarsi pale testaceous oc 

 almost whitish, darkened apically ; abdomen elongate, narrow, subclavate, with 

 thin hoary pubescence ; no vibrissae ; venter dark reddish brown, not metallic, 

 the hind margins of segments whitish. 



Habitat. — Guayaquil, May-June, 1913 (Brues), 



Closely allied to A. scminigra Ckll., but readily separated by the 

 greener abdomen, paler flagellum, etc. In Vachal's table (Misc. Ent.) 

 it runs to A. brochidens Vach. from the Argentine Republic, but is 

 not identical. 



Augochlora notophcs (Vachal) var. nothus new variety. 



Guayaquil (v. BticJncald). Alfken coll. 22. The two male speci- 

 mens before me represent a species very close to A. notophops Ckll., 

 but distinct. They run in Vachal's table to A. notophos, and are 

 provisionally referred to that species as a variety. Vachal, in de- 

 scribing the female of notophos, stated that he had no less than 32 

 specimens, from British Guiana, various parts of Brazil, Bolivia and 

 Peru. He also had seven males, from Brazil and Peru. It seems 

 unlikely that such a widespread and apparently common species should 

 not have been earlier described; and when we look in the Brazilian 

 fauna for a species agreeing essentially with notophos, we find A. 

 diversipcnnis (Lep.), which Vachal did not include in his tables and 

 evidently did not recognize. However, a single female notophos 

 which Vachal loaned me years ago seemed nearest to A. acidalia, 

 though quite distinct. It may well be that Vachal's notophos was 

 composite, and was at least largely founded on diversipennis. The 

 Guayaquil bees are quite of the type of male diversipennis, differing 

 by the dark ferruginous (instead of yellow) tarsi, the paler vibrissae 

 of first two abdominal segments, and the anterior margin of clypeus 

 narrowly dark reddish. The thickened hind margin of metathoracic 

 enclosure is angulate or bracket-like, whereas in diversipennis it is 

 evenly rounded.
