feature could be depended upon to separate all specimens of the two 

 forms. Specimens collected at Prescott since the original descrip- 

 tion was published show that in some individuals the dark bar is 

 complete, in others partially or entirely lacking. The bar occurs in 

 all specimens of h. huachucana that I have seen. The general 

 coloration of coyoterae is variable and encompasses the same range 

 of shades as the typical subspecies. 



Ball et al. (1942) indicate that coyoterae is smaller than h. 

 huachucana, but the series I have examined suggests that com- 

 parable extremes and variation in size occur in each subspecies. 

 The pronotal length of coyoterae males from Prescott varies from 

 4.3 to 5.1 mm., and that of h. huachucana varies from 4.2 to 5.2 mm. 

 (extremes from Santa Rita Mountains, Ariz., and Hachita Grande 

 Peak, N. Mex., respectively) . Females studied are also comparable, 

 those of coyoterae examined ranging in pronotal length from 4.3 

 to 5.5 mm. (both from Prescott), and Hebard (1922) recorded 

 female paratypes of which the pronotum measured 6.3 mm.
