they are widely separated at their base. The punctures in 

 the strise of the elytra are small and widely separated from 

 each other.

Somewhat the appearance of the European 0. ovatus, but 

 with the thorax much more closely and rather more strongly 

 punctured ; rather more convex, with scarcely any trace of 

 longitudinal impression. The elytra are dull ; the first and 

 second interstices are nearly flat, with a few indistinct punc- 

 tures ; the third has a slightly raised central line, which is 

 punctured, and each of the following interstices has this line 

 more distinct, more shining, and more punctured, until the 

 lateral interstice is entirely shining, convex, and closely and 

 rather strongly punctured. 



The male has the clypeus rather closely and delicately 

 punctured, the forehead still more delicately punctured, the 

 ocular canthus more strongly punctured. 



The female has two raised transverse lines, the one on the 

 vertex angulated ; the punctuation is much stronger than in 

 the male and more uniform. 



A single specimen, which is probably an undeveloped male, 

 has the punctuation of the head as in the female ; the carina 

 on the vertex is also like that of the female, but there is no 

 anterior raised line.

The arid region of Western North America has not been 

 well explored for Coccidas, but it is already known to support
