131. Pachybrachys consimilis new species 



Extremely close to circumcmctus, and possibly a geographical race of that 

 species. It differs chiefly in its very distant eyes, which in the male are sepa- 

 rated by about three times, and in the female by four times the length of 

 the basal antennal joint, the distance in the latter se.x being actuaUy greater 

 than the vertical length of the eye. The elytral vitta is even broader than in 

 most examples of circwncinctus, the lateral edge is black around the apex to 

 the suture and the two outer elytral series of punctures are more irregular or 

 confused. Size slightly larger and form more robust than in circumcinctus. 



Distribution.— The type is a female collected by Dr. Fenyes at Sugar Pine, 

 near the entrance to Yosemite Valley, California. Other examples are from 

 Tuolumne Co., July (Van Dyke); Eldorado Co., June 9 (Nunenmacher), and 

 Mokelumne Hill, May 19 (Blaisdell)— all in California. 



132. Pachybrachys litigiosus Suffrian 



Above yellow, cephalic markings and pronotal M moderate to 

 heavy, black and sharply outlined, elytra with suture, two discal 

 vittae and extreme lateral edge black. Eyes very distant, front 

 without ocular lines; front claws of male not enlarged. 



Head finely sparsely punctate, more coarsely and closely so in the triangular 

 black frontal spot; eyes distant from somewhat less to rather more than three 

 times the length of the basal antennal joint. Antennae not very slender, about 

 two-thirds as long as the body in the male, blackish in great part, tenth joint 

 less than three times as long as wide. 



Prothorax less strongly transverse than usual, not or but slightly dilated 

 posteriorly, sides feebly arcuate and moderately convergent from base to apex; 

 punctuation sparse, the punctures separated by two to three times their owti 

 diameters, not much closer laterally; side margins smooth; markings broad, 

 the black color predominating, leaving two elongate oval oblique basal spots, 

 an anterior median line, the front margin narrowly, and side margins more 

 widely, yellow. 



Elytral striae nearly regular throughout, feebly impressed discally, a little 

 deeper at sides, a few irregular punctures along the suture near the base; shield 

 wanting; sutural vitta subequal in width to the discal ones, the latter as a rule 

 slightly wider than the intervening yellow stripes; lateral stria without sub- 

 basal dislocation, lateral interspace impunctate. 



Pygidium at base, and body beneath black, the last ventral segment in part 

 yellow. Legs rufo-testaceous, the apical portions of the femora and base of 

 tibiae whitish yeUow.
