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

 Valleys, also at Fort Tejon. 



(!. punotata, Lee, Proo. A.oad. VII, 225. 



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

 their length, and less 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 by Mr. Wm, M. Gabb, which I refer to the same species, 

 although differing from the type as well as from each other, very 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 

 striee, 



A specimen in my own cabinet is smooth, almost entirely impuncturcd. . The elytra 

 exhibit very distinct stria 1 of large punctures, faintly impressed, becoming obsolete on the 

 sides and apex. 



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

 striate, the striee punctured and the interstices feebly convex and finely wrinkled. 



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

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

 and finely punctured and feebly transversely wrinkled.- The under surface is 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 of hut one species, similar variations occurring in Eleodos and Iphthimus 

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



Length .80 (type)-l.lO (2nd specimen) inch. 



This species occurs in Utah and Nevada. 



The species of this genus appear to be confined, each within its own limits, as follows: 



dilaticollis, Oregon and northern California, in and to the westward of the Coast 

 Kange, southward to the Bay of San Francisco. 



magna, central California and the great valley of the Sacramento River and Tulare 

 Lake, between the Sierras and Coast Range. 



obesa, Peninsula of California and that portion of upper California southwest of the 

 Coast Range, forming part of the fauna of Arizona. 



punctata, the deserts of Nevada and western Utah, and southward to New Mexico.
