shallowly microreticulate. Eyes rather small, transverse, 
narrow, barely extending inwardly beyond the antennal 
sockets. Antennse short, extending to just beyond the 
base of the elytra, twice as long as an anterior tibia. In 
the male the first segment is stout, the heaviest segment, 
reaching one-third across the eye ; second slender, seven- 
tenths as long as first ; third one-sixth longer than first, 
increasing gradually in thickness toward the apex where 
it is one and six-tenths times as wide as at the base. First 
two segments and base of third with cinereous pubescence. 
Fourth segment three-fifths as long as third; fifth and 
sixth equal to fourth in length, the apices of the third, 
fourth and fifth equal in thickness, wider than their bases. 
The length decreases gradually from the sixth to the 
tenth, which is five-sixths as long as the sixth. The sixth 
to the tenth are individually almost uniform in thickness. 
Last segment one and one-half times as long as tenth. 
The proportions are the same in the female except that the 
first and intermediate segments are not enlarged. Pro- 
notum subquadrate, slightly longer than broad. Midline 
not impressed or denuded. 
Elytra narrowly denuded and with a little black pubes- 
cence at the base where covered by the base of the prono- 
tum. Outer margin of anterior tibiae and top of anterior 
tarsi of male slightly denuded, the first tarsal segment 
slightly thickened. Posterior tibial spurs broadened, the 
outer slightly the broader and longer. In some of the 
males there is a small spot of black pubescence on the hind 
margin of the abdominal sternites and a mid-dorsal black 
line on the pygidium. This character is present in obesa 
and several other species in southern Mexico.
