408 AMERICAN PACHYBRACHYS (cOLEOPTERA) 



90. Pachybrachys pluripunctatus new species 



Dull dirty yellow, densely punctate, with obscure nebulous 

 dark brown or fuscous standard spots; eyes separated by the 

 vertical width of their upper lobes in the male, front without 

 ocular lines; front claws of male obviously but not very strongly 

 enlarged. Ave. length 3.5 mm. California. 



Head thickly punctate, dirty yellow, with broad vague darker standard 

 markings; eyes separated in the male by one and three-fourths times the 

 length of the basal antennal joint or rather more, and by nearly three times 

 the length of the basal joint in the female. Antennae attaining the hind coxae 

 in the male, a little shorter in the female, blackish, more or less paler toward 

 the base, tenth joint scarcely two and one-half times as long as wide. 



Proihomx moderately transverse, widest a little in advance of the base, 

 sides obviously but not strongly convergent in front; punctuation dense, 

 narrowly sparser along the side margins; M varying from broad and diffuse to 

 obsolete. 



Elytra broadly densely diffusely punctate on the disk, more or less striate 

 at sides and rear, especially in the male, the female with three feebly prominent 

 narrow and subentire interspaces included between striae one to two, three to 

 four and seven to eight, these being also detectable in the male; marginal inter- 

 space wide, closely punctate throughout; shield distinct but small. 



Pygidium blackish with rather small subapical yellow spots. Body be- 

 neath blackish, last ventral with lateral pale spot. Legs variable from rufo- 

 testaceous with black spots or bands to almost entirely fuscous. 



Length 3.1 to 3.8 mm.; width 1.6 to 1.9 mm. 



Distribution.— California: Carmel, Monterey Co., Oct. 29, type 9 (Van 

 Dyke); San Mateo Co., Aug. (Nat. Mus. Coll.); Santa Cruz Mountains (Nat. 

 Mus.); Pasadena, Dec. 22, 1 female not quite typical. 



91. Pachybrachys bajulus Suffrian 



Luteous, alutaceous, not or feebly shining, prothorax trivittate 

 with black, the vittae not or scarcely connected in front; elytra 

 narrowly black along the suture and with the lateral bead black, 

 the standard spots nearly or quite wanting except that on the 

 shoulder knob ; eyes ( d" ) slightly more widely separated than the 

 vertical width of their upper lobes; front without ocular lines; 

 elytral striae fairly regular; front claws a little larger than the 

 others in the male. Ave. length 2.4 mm. Arizona. 



Head not wider than the thorac-ic apex, front sparsely punctate in the pale 

 areas, more closely but not densely in the dark markings, which are rather 

 broad. Eyes separated in the male by fully one and three-fourths, and in the 

 female by rather more than twice the length of the basal antennal joint; 

 antennae moderate in length, the outer joints liiackish, the tenth scarcely three 

 times as long as wide.
