from the base in the female, and either nearly straight or with a slight post- 

 median angulation; punctuation moderately close, not coarse, side margins 

 smooth. 



Elytra with the striae broadly discally more or less irregular or confused, more 

 distinct on the declivity, the seventh and eighth fairly regular as a rule in the 

 male (the seventh less so in the female), a little imi)ressed and with close set 

 roimd punctures; marginal interspace with numerous punctures in basal half 

 or two-thirds; shield small or nearly wanting; marginal j^unctures of the 

 humeral lobe wanting or nearly so. 



Pygidium, under surface and legs entirely pale. 



Length 2.8 to 4 mm.; width 1.4 to 2.1 mm. 



Distribution. — Arizona: Prescott (type); Grand Canon, July 4; "Ari." 

 (Am. Ent. Soc. Coll.). New Mexico: Jemez Springs (Casey). California: 

 Bishop, June (Fenyes); '-Cal." (Horn Coll.). Utah: Utah Lake, June 20 

 (Hubbard & Schwarz). Colorado: (Beyer Coll.). Kanma: Douglas Co. 

 (Snow); Salina (Knaus). Texas: Davis Mts., July 11 (Weii/.el). 



The Kansas specimens are all females. There seem to be no 

 differences of any moment Ijetween them and the typical Ari- 

 zona form, but in the absence of males the reference here is 

 tentative.
