strong reddish tint ; stigma and nervures testaceous. Legs 

 black, the small joints of tarsi dark red; abdomen dull but 

 not dark reddish fulvous, the segments more or less dusky,

Hab. Quirigua, = type locality, eight ; one at flowers of 

 Zexmenia virgulta, Klatt, two at flowers of common yellow 

 Compositae, three (Feb. 21) at blue flowers of a species of 

 Labiatae {W. P. Cockerell) ; Gualan, Guatemala, one at 

 flowers of Vernonia aschenborniana, Schauer, one (Feb. 18) 

 without flower record ( W. P. Cockerel^). 



A relatively large species, looking a little like Melipona 

 mandacaia, Smith, but the resemblance is merely superficial. 

 It should rather be compared with Ti-iyona fulviventris, Guer., 

 which is considerably smaller and has a shining abdomen. 

 The two agree in the dense white tomentum on cheeks.
