. base feeblj roui ded, hind angles distinct, nol rounded. Elytra elongate oval, humeri 

 rounded, color piceous. Propleuras coarsely punctured. Legs ferruginous. 

 I .ength . 10-.46 inch. 



Specimens in my cabinel from Tejon and Owens' Valley, California. 



II. bacbei, Lee, Proc. Acad. 1861, 353. 



Thorax slightly broader than long, sides strongly rounded, apex truncate, base slightly 

 rounded, hind angles very obtuse or rounded. Antenna' slender, last joint longer than 

 the preceding. Elytra elongate oval, with stria- of punctures faintly marked, interstices 

 sparsi ly punctured and with slightly elevated rounded tubercles evident at least m ai the 

 apex. Propleurse with confluent reticulate punctures. Surface sub-opaque, faintly

Island of Santa Barbara, coast of California. 



II. convexulus, I. c, Proc. Acad. 1861, p. 353. 



Thorax similar to the preceding, with less rounded hind angles. The surface is 

 shining, not metallic. Elytra elongate oval, convex, faintly striate, interstices flat, very 

 sparsely punctured. Antenna' slender, outer joints gradually decreasing, last joint oval, 

 not longer than the preceding. Propleura? finely wrinkled. Easily distinguishable from 

 i'ii' preceding species, the only one with which it might he confounded by description, by 

 its more convex form, shining surface and absence of any interstrial tubercles.

A. common species in the Eastern States, easilj recognisable by the characters given 

 in tin' table and by the very deeply grooved propleurae. The last three joints of antenna' 

 are shorter and sub-equal. 



Length .28— .36 inch. 



Abundant in the Middle States.
