HARPALIN/E 301 



on the posterior side short; the third joint is slender, subparallel, 

 obtusely truncate at tip and is barely three-fourths as long as the 

 second joint. The maxillary palpi are long and very slender, the 

 third joint much longer than the fourth, which is subcylindric and 

 truncate at tip. The falciform inner lobe of the maxilla is very 

 coarsely and closely fringed within and the outer lobe is long and 

 slender, with the last joint feebly arcuate. The elytra have a long 

 scutellar stria and a singe discal puncture and the lateral series of 

 fovese is broadly interrupted medially. The terminal spur of the 

 anterior tibiae is large, elongate and pointed, the spurs of the other 

 tibiae very slender. The abdomen is without accessory punctures 

 of any kind and the last segment has two apical setae in both sexes. 

 The only sexual differences that seem to be visible reside in the 

 larger head of the male and the more acutely lobed apex of the last 

 ventral segment in that sex. The species, omitting those confined 

 to Mexico, are apparently three in number as follows: 



Head about as wide as the prothorax. Piceous-black, shining; mandibles 

 strongly rugose; prothorax not at all wider than the head across the 

 eyes, "almost three times as wide as long," narrowed posteriorly, the 

 hind angles extremely obtuse and broadly rounded, finely canalicu- 

 late, the sides rounded, narrowly margined; base broadly impressed 

 and alutaceous at each side ; elytra not at all wider than the prothorax, 

 the striae deep, impunctate; intervals almost flat; antennae, palpi and 

 legs rufo-testaceous. Length 14.2 mm. One example, taken on the 

 "San Diego trip"- LeConte. Body parallel, the head barely per- 

 ceptibly narrower than the prothorax, the latter not more than three- 

 fourths wider than long, the sides converging behind, the hind angles 

 obtuse but only moderately broadly rounded; elytra not at all wider 

 than the prothorax, and nearly three times as long, parallel, with 

 straight sides, evenly and circularly rounded at apex and with long 

 scutellar stria. Length 17 mm. Mexico (Guanajuato and Oaxaca).

2 Form stout, oblong, subparallel, convex, shining, blackish-piceous 

 throughout above, paler and more rufous beneath, the legs testaceous; 

 head (cf ) four-fifths or ( 9 ) scarcely more than three-fourths as wide 

 as the prothorax, rufescent anteriorly; mandibles flat and strongly 

 rugose on their upper surface; eyes rather small, prominent; antennae 

 testaceous, extending slightly behind the thoracic base; mentum not 

 transversely concave; prothorax twice as wide as long, widest near 

 apical third, the sides strongly rounded anteriorly, rapidly con- 

 verging and less rounded posteriorly, the hind angles extremely
