which the individual hairs are unicolorous. The discal 
stripe on the elytra is not as prominent as in virgulata 
and southeastern Arizona specimens. Arizona spec- 
imens, from the southeastern part of the state, have the 
ground color brown and the pubescence brown at the 
base and white at the apex, and with the discal stripe 
very distinct. There seems to be no morphological dif- 
ference between the two groups and it must be presumed 
that the range is continuous in northern Chihuahua. 
Occasional specimens from Arizona have the pubescence 
very similar to western Texas specimens. The south- 
eastern Arizona specimens tend to be a little stouter and 
shorter than the Texas series or southwestern Arizona 
virgulata.
