404 AMERICAN PACHYBRACHYS (cOLEOPTERA) 



black, last ventral segment more or less pale. Legs pale with the usual dark 

 spots or rings on the thighs and dark shades on the tibiae. 



Length 2.85 to 3.6 mm.; width 1.65 to 1.9 mm. 



Distribution.— California: Giant Forest, July 7, type cf , collected and given 

 me by F.S.Daggett; SouthForkof Kings River, Fresno Co. 5,000 ft., July4 (Van 

 Dyke); Lake Tahoc, July 11 (Hubbard & Schwarz) ; Eldorado Co. (Van Dyke.). 

 Utah: (Am. Ent. Soc. Coll.). Colorado: Buena Vista (Wickham); Garland, 

 June 25 (Hubbard & Schwarz). 



This species seems to be more than usually variable; scarcely 

 any detail is constant, and an accurate description of any indi- 

 vidual will almost surely fail in some respect when applied to 

 another. This is especially notable in the series from Lake Tahoe, 

 yet there can be scarcely a doubt that they are specifically 

 identical. The width of the front between the eyes is exception- 

 ally inconstant, varying from about one and one-third to fully 

 one and three-fourths times the length of the basal antennal 

 joint, this latter variable in size also. The punctuation of the 

 elytra is as a rule quite diffuse or irregular but in one or two speci- 

 mens the serial arrangement of punctures is much more evident. 

 On the whole the species is strikingly suggestive of meJanostictus, 

 but this latter has distinct ocular lines, small front claws in the 

 male, and as a rule the eyes are more distant and the elytral 

 punctuation less diffuse. 



86. Pachybrachys badius new species 



Head and prothorax reddish brown, the elytra darker; pro- 

 thorax with side margin, narrow median anterior line and two 

 basal spots yellow, these discal marks sometimes indistinct; 

 elytra with more or less of the raised basal margin, some small 

 anterior spots, the shield and a larger post median lateral spot 

 bright yellow. Eyes (cf ) a little more distant than the vertical 

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

 claws of male distinctly enlarged. Ave. length 3.2 mm. South- 

 ern California. 



Head not wider than the thoracic apex, front rather densely and coarsely 

 nearly evenly punctate, median line somewhat strongly impressed toward the 

 vertex, markings broadly suffusfnl. Eyes separated in the male by about 

 one and three-fourths, and in ihv female by about two and three-fourths times 

 the length of the basal antennal joint. Antennae very thin, about four-fiftlis 

 as long as the body in the male, the tenth joint nearly four times as long as 

 wide; in the female scarcely two-thirds the length of the botly, the tenth joint 

 barelv three times ns long as wide.
