NORTH OF MEXICO. 



Abundant in California from San Francisco southward in the Sacramento and Tulare 

 Valleys, also at Fort Tejon. 



C. puncl ata, Lee, Proc. A.cad. VII. 225. 



Differs in the proportions of the thorax. The elytra are also broader in proportion to 

 their length, and le>- rounded on the sides, and rather suddenly declivous behind. This 

 species was described from an unique specimen from an unknown locality. Since that 

 time three others were collected bj Mr. Win. M. Gabb, which I refer to the same species, 

 although differing from the type as well as from each other, verj slightly however, in 

 form, but considerably in sculpture. 



The typical specimen is rather densely but finely punctured on the thorax as well as 

 elytra. There is a faint indication of an arrangement of larger punctures in indistinct 

 stria". 



\ specimen in my own cabinet is smooth, almost entirely impunctured. The elytra 

 exhibit very distinct stria' of large punctures, faintlj impressed, becoming obsolete on the 

 sides and apex. 



Another specimen has the fine punctation quite evident. The elytra are less feebly 

 striate, the stria 1 punctured and the interstices feebly convex and finely wrinkled. 



The fourth specimen reproduces the dense puncturing of the type, hut the elytra are 

 deeply striate, the interstices convex. The stria' are coarsely and the interstices densely 

 and finely punctured and feebly transversely wrinkled. The under surface i- more evi- 

 dently punctured than the two preceding species, less, however, than in the typical form. 



Notwithstanding these variations of sculpture, these four specimens are considered as 

 representatives ofbut one species, similar variations occurring in Eleodes and Iphthimus 

 to such an extent as to render it almost impossible to define varieties.
