no males have been collected. However, the more posterior dark 
mark on the elytra shows no sign of a posterior excavation, as is 
present in alvarado and vafer. The distinctive erect setae on the sides 
of the prothorax are matched in alvarado and approached in vafer, 
but are also approached in salvadorensis in the second subgroup. 
No other species has such differences between the broad and narrow 
scales, but there is some difference in vafer, alvarado and salva- 
dorensis; the tendency may be more a function of denseness of scales 
than relationship. The long setae on the underside of the horn are 
matched in vafer and hinted at in some others in the third subgroup, 
salvadorensis in the second, and intermixtus in the first. The setae 
on the horn, and matching setae on top of the head, as well as the 
erect setae on the top of the head that outline the horn, probably 
have an adaptive value in keeping sand grains out of the space 
between head and horn when the beetle is digging. Degree of devel- 
opment might very well be habitat-related.
