424 AMERICAN PACHYBRACHYS (COLEOPTERA) 



103. Pachybrachys relictus new species 



Yellow, with moderate to broad, often more or less confluent 

 fuscous standard markings; eyes moderately distant; antennae 

 nearly as long as the body in the male; front without ocular lines; 

 front claws not enlarged in the male. Ave. length 2.9 mm. New 

 York to Tennessee. 



Head not appreciably wider than the thoracic apex, rather closely punctate 

 and broadly maculate, the dark areas predominating. Eyes separated by 

 about one and three-fifths (cf ) or two ( 9 ) times the length of the basal anten- 

 nal joint, their distance apart evidently greater than the vertical width of their 

 upper lobes. Antennae (cf ) nearly attaining the elytral apex, the tenth joint 

 nearly four times as long as wide, yellow, with the outer joints and the upper 

 surface of the basal two joints fuscous. 



Prothorax moderately transverse, sides moderately arcuately narrowed from 

 just before the base, M usually heavily marked leaving two basal spots, an 

 anterior median one, the side margins and front angles, pale; punctuation 

 moderately coarse and close, a little uneven as usual. 



Elytral disk with confused punctures in the baso-sutural region, striae dis- 

 tinctly impressed, especially at sides and rear, where they are well defined, 

 becoming more or less irregular or broken at middle of disk; submarginal stria 

 with strong subhumeral dislocation; marginal interval not punctured; shield 

 small, yellow; standard spots usually broad, sometimes isolated, but often 

 with the discal series tending to suffusion in the sutural region, and often 

 confluent with the corresponding marginal spots so as to leave the apex and 

 two broken transverse fasciae yellow. 



Pygidium fuscous, with the usual apical yellow spots, which vary much in 

 size and may or may not be confluent with each other and with the two small 

 spots at the middle of the outer margins; entirely dark in one female. Body 

 beneath blackish, a yellow spot at side of last ventral segment. Legs black and 

 yellow, the base and apex of middle and hind thighs, and the base of the tibiae 

 pale yellow. 

 Length 2.75 to 3 mm.; width 1.5 to 1.6 mm.

This species is rather widely dispersed in the northeastern 

 United States and by good rights should possess a name given 

 by one of the older authors, but after careful investigation I am 

 forced to believe it as yet undescribed. Notwithstanding its 

 wide dispersion it seems to be rather scarce, or at least only
