j) This large series of fresh specimens shows a remarkable range of 

 {variation, both sexes varying greatly both in color and size. The 

 [females are more variable in color while the greatest variation in size 

 ioccurs in the opposite sex. The posterior femora varj^ from 10 to 14 

 'millimeters in the males and in the females the color ranges from 

 Preddish j^ellow to fuscous and the elytra of ])oth sexes vary from 

 almost immaculate to quite conspicuouslv spotted with black. Some 

 of the rufous tinted females approach ^>^/yv///d/?^7;i somewhat, inasmuch 

 as the lateral caringe of the thorax do not seem quite so much con- 

 Istricted mesially as usual and the disk of the pronotum is unicolorous.

Four males and eight females referable to this species were taken 

 at Fort Collins on August 19 and one pair at Denver on July 11; the 

 latter were taken en copula. They all agree in having the elytra much 

 more abbreviated than in elliottl and the pronotum is more generally 

 |less angulate. The tegmina of the males are inunaculate but those of 

 'the females are noticeably spotted with l)lack, sometimes however (pute 

 dind}' so.
