AMERICAN COLEOPTERA. 127 



Townseud at Navajo Springs, Ariz. ; southwestern Kansas, by Prof. 

 Williston, and along the line of the Union Pacific Railway from 

 Hayes to Wallace. Usually the only markings are a transverse 

 white abbreviated line at the middle, and sometimes a round 

 humeral dot, but in the collection of Mr. Harris are specimens with 

 middle band and two humeral dots, and with middle band and two 

 apical dots. Above, this species is not hairy, save on the front of the 

 head and the scape of the antenna?; but beneath, the palpi, legs, flanks 

 of thorax and pectus are quite thickly clothed, and there are a few 

 hairs also on the abdomen. * The labrum is short and truncate in 

 front and obscurely one toothed. The interocular striae are coarser 

 than usual. Well preserved specimens are of an exceedingly brilliant 

 coppery red color, but I have also seen nmch duller specimens.

 " tures, which are nearly obliterated near the tip, with a humeral dot
