H. C. FALL 351 



This species is easily recognized by the small size, pale color, 

 subequal elytral striae, very distant eyes,- fine ocular lines and 

 small front claws in the male. It is cjuite widely dispersed in the 

 Rocky Mountain region. After a careful examination of the 

 type of sevier Bowd. I am unable to separate it from coloradcnsis. 

 It differs from a cotype of the latter, kindly given me by ^Ir. 

 Bowditch, only in being a grain stouter, and more yellow; the 

 marginal interval of the elytra is a bit more numerously punctate 

 basally and there are three punctures behind the middle; this, 

 however, is everywhere a somewhat variable character. 



33. Pachybraehys minor Bowditch 



^'crv similar to coloradensis, and distinguishable as follows: The size is 

 slightly larger, color more distinctly yellow, surface less shining, minutely 

 alutaceous, prothoracic markings more evident though small, and diffuse as 

 a rule, and occasionally entirely wanting; side margins of prothorax more 

 widely smooth. Eyes less distant, separated in both sexes by less than their 

 own length, though but slightly so in the female; in the male by about two and 

 one-half times the length of the basal antennal joint. Ocular lines very con- 

 spicuous and widely distant from the eyes, about two-fifths the distance to 

 the median line in the male. EMral striae nearly as in coloradensis, the 

 fifth and sixth more commonly confused at the middle; marginal interspace 

 without punctures; shield fairly disticnt; abdomen often entirely yellow. 



Length 2.3 to 2.9 mm. 



Distribution. — Arizona: Walnut — type (coll. by Wickham); Riverside 

 (\Mckham). A'ew Mexico: (Leng Coll.). California: Pomona; Pasadena; 

 Azusa, June and July; Los Angeles Co. (Coquillett in Xat. i\Ius. Coll.); Inde- 

 pendence, July 7. (Wickham) not quite t^^)ical. Texas: a single specimen 

 without specific locality seems to be identical. 



\av. a 



Two examples from San Felipe, Lower California, sent me by 

 Mr. Beyer, are of a more grayish yellow and show a line of punc- 

 tures on the marginal interspace extending behind the middle; 

 the form also seems a trifle stouter. 



Although comparison is here made with coloradensis to which 

 it is closely allied and near which it stands in the table, the resem- 

 blance of minor to some specimens of viercurialis is even more 

 striking, but the latter is at once separable by the absence of 

 ocular lines.
