tive, distal portion strongly curved and then running straight to the expanded 

 tips, which have the inner angles about right-angled, but the outer angles 

 strongly produced, the distal margin between the two corners being slightly con- 

 cave. The outer margins of the distal half are roughened and the characteris- 

 tic granulations appear over the entire apical portion. Connective heart-shaped, 

 the apex broadly rounded, ffidagus very characteristic of the species, having 

 two pairs of basal processes, the upper ones shorter, the lower ones reaching 

 nearly to the tip of the apical process, at the extreme fimbriate tip of which 

 the penis opens. Both pairs of basal processes bear teeth along the margins. 



Distribution. All of the twenty-five specimens, except one from 

 Colorado, one from Morton county, Kansas, and one from Ashfork, 

 Ariz. (Barber and Schwarz), were sent the writer by Doctor Ball, 

 who obtained them from the following localities: Soldier, Dixie, 

 Richfield, Monroe, Moab, Utah; Fort Collins, Grand Junction, 

 Delta, Dutch George or Poudre Canyon, Colo.; Coolidge, Kan.; 

 Wenatchee, Wash. ; Phoenix, Ariz. There are specimens also in the 

 collection of the Colorado Agricultural College from some of these 

 localities. 



Remarks. The specimen from Moab, Utah, seems to be different 

 from the other specimens of this species in that it is lighter in color, 

 has a broader head, and longer and more pointed elytra. There be- 

 ing only one specimen of its kind, however, the writer prefers to 

 place it here to describing it as a new species from a single speci- 

 men.

The following is the original description: 



Acinopterus acuminatus, var. variegatus, n. var. Form and structure of the 

 species, but much lighter colored. Vertex, pronotum and scutellum inclined 

 to be reddish, especially in the male. Elytra whitish pruinose, nervures green- 

 ish, not margined, except towards apex and along sutural margin, three fuscous 

 points along the suture, and sometimes one on the disc of each elytron. 



Described from twenty-four specimens from Colorado and Arizona. 



The following is the writer's description: 



The members of this variety are hke viridis except in color. 



Color. General color, brown. Vertex, pronotum and scutellum greyish or 

 brownish, sometimes with a reddish tinge. Tegmina pale, but with nervures 

 margined more or less throughout, especially along sutural and costal margins 

 and apically, giving them a decidedly variegated appearance. 



Distribution. Eight specimens examined are from Doctor Ball's 

 collection and were taken by him at Fort Collins and Denver, Colo.
