reach the suture of the antecoxal piece; the space between the mar- 

 gins is impunctate and shining. The posterior coxal plates are 

 broadly, separately rounded, without any appearance of angulation, 

 and with the punctures large but very shallow and indistinct. The 

 apices of the elytra are not rounded, as stated by Mr. Matheson, but 

 obliquely truncate and evidently sinuate. 



The males may be separated from the females by the thickening 

 of the joints of the front and middle tarsi, especially the first and 

 second joints of those of the middle legs. 



It is probably pretty well known that the females have the elytra 

 tuberculate as well as the males and are not, as supposed by Mr. 

 Crotch, " very hard to separate from i2-punctatus." 



The species has quite a range of habitat and I have specimens 

 from Provo (H. Soltau), Virgin River (G. Weidt), and Mill Creek 

 (Hub. & Sz), Utah; Tacoma, Wash.; Corvallis, Oreg. (A. R. 

 Woodcock) ; Peachland (J. B. Wallis), and Frazer Valley (A. Weidt), 

 Brit. Col.; Alburquerque, N. Mex. (H. F. Wickham), and from nearly 

 all parts of California. 



Peltodytes simplex Leconte. 



In this species the mid-metasternum is not deeply impressed be- 

 tween the middle coxse, as is the case in callosiis, but nearly flat, lightly 

 impressed each side behind the cox?e and with the margins short, 

 hardly reaching half way to the margin of antecoxal piece, smooth 

 and shining between the margins with a few deep punctures at their 

 extremities. The hind coxal plates are rather more deeply punctate 

 than in callosiis and the apices are subangulate. 



Last abdominal segment smooth and shining. 



The under plane of the body is rather flat, not strongly arched 

 longitudinally at the mid-metasternum, or " chicken-breasted," as in 

 cdcntuhis and some other species. 



I should not call the prosternal process " steeply declivous in 

 front," but strongly arched almost from base to gula without distinct 

 apex or limiting margin. The thighs of posterior legs are dark 

 brown in color, and the males have the joints of the front and middle 

 tarsi thickened, but not pedunculate. All the specimens I have seen 

 are from San Diego, Los Angeles, Campo and San Bernardino, Cali- 

 fornia.
