396 AMERICAN PACHYBRACHYS (cOLEOPTERA) 



the punctures along the side margin of the jironotum are smaller 

 and paler than in nuhigenus. The width of the front between 

 the eyes shows quite a little variation and the ocular lines are in 

 some examples so close to the eyes as to appear to be wanting. 

 Just such variations have been observed in punctatus. Nubi- 

 genus is somewhat similar in the dorsal elytral cloud to the fol- 

 lowing species — punicus — which see for a statement of differences. 



79. Pachybrachys punicus new species 



Yellow, prothoracic markings rust colored and more or less 

 ■disintegrated and diffuse, elytra with fuscous dorsal clouds made 

 up of the more or less connected and suffused inner series of spots; 

 the outer spots feeble or wanting, except the posterior one, which 

 is often connected with the inner cloud; eyes (d^) much more 

 distant than the width of their upper lobe; front with ocular 

 lines, distant from the eyes; outer four or five elytral striae entire 

 or nearly so and fairly regular; front claws of male a little en- 

 larged. 



Ave. length 2.75 mm. Southern California. 



Head rather sparsely punctate, front almost entirely yellow, the median 

 impressed hne sometimes faintly rust colored, vertex spot present; ocular lines 

 distinct and at about two-fifths the distance from the eyes to the median line 

 of the front. Eyes separated fully twice the length of the rather large basal 

 joint of the antennae in the male, and by three times the length of the basal 

 joint in the female. Antennae pale basally, outer joints blackish, fully three- 

 fourths the length of the body in the male, not much more than half the length 

 of the body in the female, tenth joint about three times as long as wide. 



Prothorax widest at basal fourth, evidentlj' but not strongly narrowed in 

 front, sides feebly arcuate or nearly straight anteriorly, roimded in a little 

 basally, with a slight sinuation before the angles; punctuation somewhat 

 uneven, fairly close in the diffuse rust colored markings, elsewhere sparse, 

 the side margins smooth. 



Elytra densely irregularly punctate in a moderate sized baso-sutural triangle, 

 elsewhere subregularly striate, striae finely impressed, eighth nearly straight 

 without subbasal dislocation; marginal interspace with a series of coarse punc- 

 tures which is usually more or less interrupted medially; shield large and con- 

 spicuous, yellow, contrasting with the dark markings. 



Pygidium, body beneath and legs as in the preceding species. 



Length 2.45 to 3.05 nmi.; width 1.25 to 1.7 mm. 



Distribution.— California: Pomona, foothills, June 11, o^ ^ypc, C'larcmont 

 (Baker); Los Angeles Co. (Coquillett in Nat. Mus. Coll.). Lower California:
