One specimen found on the Colorado river, below the Gila. The punctures of the 
under surface are less deep at the middle of the anterior segments of the abdomen; the 
last ventral segment has no subapical carina, but the groove is distinct. The two outer 
striae of the elytra are confluent behind the humerus.

Two specimens found by Dr. T. H. Webb on a journey from El Paso to San Diego. 
The front is very slightly impressed: the sides of the elytra, from the prolongation of the 
humeral angles, are deeply sinuate near the base; their outline in the male is somewhat 
cuneiform, narrowing in a slight curve from the base, they are strongly serrate behind, and 
the tip is conjointly rounded: in the female they are nearly parallel, and slightly sinuate for 
three-fourths the length, then obliquely narrowed to the apex. The spots of the disc are 
seven or eight in number, forming a series on the 3d, 4th and 5th intervals, and are un¬ 
equal in size: the other spots are, a humeral dot, three marginal spots occupying two in¬ 
tervals, and finally three spots alternate with the marginal ones, on the 3d interval from 
the side; these last are tinged with scarlet: the two outer stricc are confluent anteriorly. 
The punctures of the under surface are more sparse, but not smaller at the middle than at 
the sides: the last ventral segment has a very broad carina and the usual groove.
