 The middle of the raesothorax is shining, with rather sparse 

 strong punctures. 



Ha'K Gualan, Guatemala (W. P. Cockerell). Two at 

 flowers of Vernonia aschenhorniana, 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. 



Exomalopsis pulchella^ Ci'esson. 



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

 one has the hair behind ocelli pale ochreous, the other 

 (from flowers of Zexmenia virgulta, Klatt) has hair behind 

 ocelli and on scutellum black, and the stigma and nervures 

 bright ferruginous. 



Thygater cocJcerelli (Crawford). 



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

 flowers of no. 420. 



Thxjgater nigravillosa (Crawford). 



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

 Feb. 20, at flowers of Ipomcea sidafoUa. Choisy. 



Leptergatis armata (Smith). 



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

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

 one at flowers of Zexmenia virgulta). 



It is almost impossible to separate the females of this 

 from Leptergatis toluca {Melissodes tolncn, 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,
