The-V(Mv iiitiM-cstins:; scries of this species contained in the collec- 

 tions available for study presents several facts in elaboration of the 

 original description of this species, based on a single female from 

 southern Arizona. One is that considerable size variation is present 

 in l)otii sexes. I)ut more i)articularly in the male. Another is that in 

 the male the ventral ridge of the caudal femora is more elevated and 

 distinctly dentato-serrate (often strongly so), while in several of the 

 specimens of the same sex the proximal fourth of the caudal tibiie are 

 strongly valgate. beyond which they are straight. 



Measurements are here given of the maximum specimens of both 



sexes.

This series has been compared with a representation from Florence, 

 Flagstaff and Phoenix, Arizona. There is considerable variation in the 

 depth of the fuscous coloration and also in size, the latter being as 

 individual as color variation, the largest male and the smallest females 

 being from the same locality (San Bernardino Ranch). All the speci- 

 mens are of the macropterous type.
