Records of Bees. 29 



flaG^elUrn black above, clear ferruginous beneath ; te^^ulpe 

 brio;ht ferruginous. The type has the hair of thorax: above 

 bright orange-fulvous, and that of abrlomen all (except the 

 black) warm reddish ; the other specimen has the hair of 

 thorax above pale ochreous and the median bands on second 

 and following abdominal segments white. The hind margins 

 of the abdominal segments are broadly more or less pallid. 

 The middle of the mesothorax is shining, with rather sparse 

 strong punctures. 



Ha"^. Gualan, Guatemala {W. P. Cockerell). Two at 

 flowers of Vernonia aschenborniana, Schauer. 



I treat this as a subspecies of M. tepaneca, on account 

 of the geographical proximity of that insect, but by the 

 characters it is actually closer to the Texan M. masuca. 



E.vomalopsis pulchella, Cresson. 



Quirigua, Guatemala {fV. P. Cockerell). Two females ; 

 one has the hair behind ocelli pale ochreous, the other 

 (from flowers of Zcxineaia virguUa, Klatt) has hair behind 

 ocelli and on scutellum black, and the stigma and uervures 

 bright ferruginous. 



Thygater cockerelli (Crawford). 



Quirigua, Guatemala (JV. P. Cockerell). One female, at 

 flowers of no. 420. 



Thygater nigravillosa (Crawford). 



Quirigua, Guatemala {W. P. Cockerell). Two males, 

 Feb. 20, at flowers of Tpomcea sidafolia. Choisy. 



Leptergatis armata (Smith). 



Quirigua, Guatemala {W. P. Cockerell). Twenty females 

 (mostly Feb. 20), four males (two, Feb. 20; one, Feb. 12; 

 one at flowers of Zexmen'ia virgulta) . 



It is almost impossible to separate the females of this 

 from Leptergatis toluca [Melissodes tolucn, Cresson), but the 

 males are easily separated by the hind legs. 



Leptergatis toluca (Cresson). 



Gualan, Guatemala [TV. P. Cockerell). One male, Feb. 15, 

 at flowers of Cordia alba, E. & S.
