Dec, I9I4.] Cockerell: Bees From Ecuador and Peru. 323 



Habitat. — San Bartolome, Peru (type locality), 2 females, July, 

 1913 (Bnies) ; Guayaquil, May-June, 1913, 2 females (Brues). 



Another member of the E. globosa group, but quite distinct by the 

 character and colors of the pubescence on hind legs and abdomen. 



For ready reference, I give a table to separate the small An- 

 thophorid bees described above: 



Hair of thorax black i 



Hair of thorax at least partly pale 2 



1. Mesothorax shining, strongly punctured Tetrapedia alflceiii Ckll. 



Mesothorax appearing dull, without evident punctures. 



Clialepogcniis buchzvaldi Ckll. 



2. Females 3 



Males S 



3. Hind tarsi without black hair ; abdomen mainly covered with orange hair. 



Leptometria pacifica Ckll. 

 Hind tarsi with much black hair 4 



4. Hind tibiae without black hair on outer side. . . .Exomalopsis zexmcnicc Ckll. 

 Hind tibias with black hair on outer side Exomalopsis bniesi Ckll. 



5. Clypeus yellow Leptometria pacifica Ckll. 



Clypeus black ; tarsi red ExoDialopsis zexmenia Ckll. 



Agapostemon nasutus Smith. 



San Bartolome, Peru, July, 1913, i male {Brues). 



Augochlora binghami Cockerell. 



Guayaquil, May-June, 1913, i female (Brues) ; Guayaquil, a very 

 purple female (v. Buchwald; Alfken coll. 21). 



In the absence of males, the reference to A. binghami is perhaps a 

 little uncertain, but the purple tints and prominent lateral angles of 

 prothorax agree with those of A. binghami from Guatemala. 



Augochlora metallica (Fabricius). 



Guayaquil, 3 females (v. Buchzvald; Alfken coll., 23) ; Guayaquil, 

 May-June, 1913, i female (Brues). 



I think that this is undoubtedly A. metallica. at least as interpreted 

 by F. Smith, who states that it comes from Colombia. It accords 

 exactly with my notes and recollection of Smith's specimens in the 

 British museum. It is very close to the Brazilian A. iheringi Ckll,, 

 but has the abdomen green right across the segments, except the 

 black hind margins. The first r. n. enters the apex of second s. m. or
