 June 24 (Hubbard & Schwarz); "Ut." (Liebeck Coll.). Oregon: Huntington 

 (Hubbard & Schwarz, and Leng Colls.). California: Pomona, April 23 to 30;

 Los Angeles Co. (Coquillett— Nat. Mus. Coll.). Lower California: San Felipe 

 (Beyer). 



One of our commonest and most widespread species. Bow- 

 ditch"^ has called attention to the fact that the name viduatus 

 has long been wrongly used for this species. 



129. Pachybrachys sublimatus new species 



In size, form, .sculpture and structure closely related to hiviitatus and allies; 

 the foi-m is almost exactly that of bivitlalus, the lustre somewhat dull, cephalic 

 markings black, the frontal triangle often very narrowly attaining the vertex 

 spot and frequently failing to reach the antennal foveae. 



Prothorax rather more densely punctate than in bivittatus, the side margins 

 less distinctly smooth, disk with very vague and diffuse reddish brown shades 

 representing the M, the lateral branches usually more pronounced. 



Elytra sometimes with a single narrow black vitta, with or without traces of 

 lateral spots, but usually without markings, the sutural bead and portion of 

 lateral edge black, precisely as in bivittatus; submarginal stria much confused, 

 the marginal series of punctures more or less irregular, in which respect the 

 jjresent species is more nearly in agreement with consimilis. The eyes are 

 separated in the male by two to two and one-half, and in the female by about 

 three times the length of the basal antennal joint. Legs — except last one or 

 two tarsal joints — entirely pale. 



Length 3.8 to 4.35 mm.; width 1.8 to 2.3 mm. 



Distribution. — California: San Bernardino Mountains, July 12, types d^ 

 and 9 ; Pasadena, July 19; Claremont (Baker). 



130. Pachybrachys circumcinctus Crotch 



Closely allied and gciiorally similar to birittatus, differing as follows. The 

 size is on the average a little smaller, surface more shining, the alutaceous sculp- 

 ture often nearly lacking (normally quite distinct in bivittatus), elytra each with 

 a single broad black vitta, the lateral edge and epipleuron black around the 

 lobe nearly to base; prothorax rufous or rufo-testaceous with side margins paler 

 and often with three small more or less distinct darker to blackish basal spots; 

 eyes separated in the male by about two and one-half and in the female by 

 rather more than three times the length of the basal joint of the antennae, the 

 distance in the female, however, not quite as great as the vertical length of the 

 eye; the two outer series of elytral punctures less regular than in birittatus; 

 body beneath black, the apex of the last ventral, on each side of the middle, 

 pale, the sid(>s of the body usually not pale; tibiae sometimes in part blackish, 

 the tarsi more evidently so than in bivittatus. 



Length 3.7 to 1.2 mm.; width 2.1 to 2.4 mm.
