San Jose, 5 9 , May 25th to June 9th. 



The abdomen is somewhat similar to that of rubricata, but the 

 apical margins of the segments are whiter and more contrasting. It 

 differs widely from that species in the light pubescence of the thorax. 



Apparently like modesta in the pubescence of the thorax, but that 

 species does not have any red oh the abdomen nor the apical mar- 

 gins of the abdominal segments light.

 cence black, except a little at sides of face, a small spot between antennte, cheeks 

 entirely, narrow line over tegulse extending around rear of mesonotum, more or 

 less on metathorax, base and apex of abdomen and under side of thorax and 

 abdomen where it is white; wings dusky, nervures dark; legs dark, obscurely 

 ferruginous behind, small joints of tarsi reddish ; abdomen sericeously lineolate, 

 finely and sparsely punctured, apical margins of segments reddish ; apex of abdo-

Differs from the descriptions of the other males in the almost 

 entirely black pubescence of the thorax ; montezuma has the pubes- 

 cence of the thorax anteriorly black, posteriorly rufous ; albilabris 

 9 has the pubescence above black but no light, apical margins of
