H. C. FALL 327 



Average size somewhat smaller, and scarce!}' as robust ; pubescence longer 

 and more conspicuous; prothorax slightly less transverse, less strongh- narrowed 

 in front, the sides more arcuately prominent behind the middle; punctuation 

 of the elytra scarcely or but little coarser than that of the prothorax; upper 

 surface, more often of the ehira, more or less variegated with diffuse rufous 

 spots or markings. 



Distribution. — Occurs in Texas, Colorado, New ^Mexico and 

 Arizona. Described from Mexico. The following localities 

 are represented before me. 



Texas: Texas (Belfrage). Colorado: "Col" (Baker); Colorado Springs, 

 along the creeks (^\'ickham). A'ew Mexico: San Ignacio, June 27 (Cockorell); 

 Cloudcroft, June 14 (Knaus), May 22 (Viereck); Silver City (Dury); near Las 

 Vegas Hot Springs, July (Snow). Arizona: Huachuca Mts., May 16 (Clem- 

 ence); Palmerlee, July 27 (Wenzel); Chiricahua Mts., May 16 (Clemence). 



"While the characters given above would seem to be sufficient 

 to separate haematodes from pube.scens, they are I find all subject 

 to variation and manj- examples are fairly intermediate between 

 the typical forms; I am therefore not at all sure of their specific 

 distinctness. 



3. Pachybrachys integratus new species 



Yellowish, thinly pubescent above, with broad suffused pale 

 brown to fuscous markings; surface shining, without alutaceous 

 sculpture; eyes narrowly separated. Ave. length 3.7 mm. Cali- 

 fornia and Arizona. 



Head closely and evenly punctate, an impressed line between the ej-es; 

 entirely pale, or with the impressed line and a small spot at base of antenna 

 darker. Eyes large, separated in the male by a distance not greater than the 

 length of the second antemial joint; in the female by rather less than the 

 length of the first two joints. Antennae very slender throughout, subequal in 

 length to half the body in the male, somewhat shorter in the female, entirely 

 rufo-testaceous or with the outer joints darker. 



Prothorax widest at or a little behind the middle, sides strongly arcuate, base 

 a little wider than the apex; punctuation rather close, fairly regular, with 

 scattered minute interstitial punctures, more obvious in the female; margins 

 not smoother; markings diffuse. 



Elytra j)arallel or slightly narrowed behind, siiles moderately sinuate behind 

 the humeri; punctures rather fine and confused in a small triangular scutellar 

 region, the next two discal striae and the two outer ones well defined, the inter- 

 mediate region confusedly punctured; the strial punctures moderate in size 

 basally but finer toward the apex. The pubescence arises from a system of 

 interstitial punctures which are barely visible basally but are gradually larger
