348 AMERICAN PACHYBRACHYS (cOLEOPTERa) 



Head sparsely finely punctate, front broadly feebly convex, spots small or 

 nearly wanting; ocular lines wanting or feebly indicated and close to the eyes; 

 eyes separated by from rather more than twice to nearly three times the 

 length of the basal antennal joint in the male, and by from three to three and 

 one-half times the length of the basal joint in the female; antennae slender, 

 blackish in outer half, fuUy two-thirds the length of the body in the male, the 

 tenth joint more than twice as long as wide. 



Prothomx moderately transverse, sides nearly straight and moderately 

 convergent from the base, feebly roundly dilated at about the basal third, 

 especially in the male, punctuation rather fine and not very close, side margins 

 smooth. 



Elytra twice as long as the prothorax, striae lightly impressed and for the 

 most part distinct, the intermediate ones (3 to 6) often sinuous or somewhat 

 confused, seventh and eighth regular, marginal interspace rarely completely 

 impunctate, typically with a few punctures at and behind the subbasal dis- 

 location of the eighth stria; baso-sutural triangle of confused punctures rather 

 small; shield large, elongate, occupying about two-thirds the post-median 

 part of the interval. 



Pygidiimi black at base, a median spur and two small subdetached spots of 

 same color. Legs pale, median femoral clouds barely visible. 



Length 2.5 to 3.2 mm.; width 1.2 to 1.7 mm. 



Distribution. — California: Isabella, Kern Co., June 1 (Pilate), type cT) 

 Olancha, Kern Co., June 4 (Fenyes); Siskiyou Co., July (Nat. Mas. Coll.); 

 "Cal" (Am. Ent. Soc. Coll.). Utah : Salt Lake, June 13 (Hubbard & Schwarz). 



In the type series there is more or less evidence of faint ocular 

 lines very near the eyes. These are not noticeable in the Siski- 

 you specimens nor in the series from "Cal" (Am. Ent. Soc. Coll.). 

 These last — all females — differ further in having the front more 

 coarsely and closely punctate. These differences do not seem 

 of much moment, more especially since there is a tendency 

 toward a somewhat coarser punctuation of the front in the females 

 of the typical form, and moreover in this sex the faint ocular 

 lines are least discernable. A small male from Monterey, Cali- 

 fornia (collected by Fenyes), is placed here provisionally. It has 

 the elytral punctures darker and seemingly coarser, and the point 

 of the shoulder knol) dark; it may possibly be a variety of laevis. 



30. Pachybrachys parvinotatus new species 



Yellow, lustre dull, head and prothorax finely alutaceous, the 

 former with the standard marks dark l^rown or l)lackish, the 

 latter usually with three small basal fuscous spots, the middle one 

 usually darkest, the lateral ones often faint; elytra with the 

 point of the shoulder knot), and the sutural edge blackish; front
