in abftorme^ close-set, the occipital spot rather large and ill-defined ; 

 prothorax large, nearly as in ab^torjne but less coarsely punctured 

 throughout, the punctures similarly arranged, the basal angles 

 rather more than right, not rounded but not at all prominent; 

 scutellum well developed, transverse, finely punctured almost 

 throughout; elytra nearly as in abnortne but narrower, similarly 

 but much more finely punctured throughout; abdomen finely, 

 sparsely punctured medially, only a little less finely on the 

 basal segment. Length 7. t; mm.; width 3.0 mm. California 

 (Needles) f austum n. sp. 



Form stout, parallel, convex, polished, rufous in color throughout, 

 sometimes nearly black ; head large, nearly three-fifths as wide as 

 the prothorax, broadly truncate, the sides only moderately con- 

 verging but strongly arcuate before the eyes, the punctures coarse, 

 somewhat irregular, close-set but not very dense, the occipital 

 spot well defined ; prothorax large, three-fourths wider than long, 

 the sides moderately rounded, more converging near the apex, 

 the basal angles slightly obtuse, not rounded but not prominent, 

 the punctures rather small medially and notably sparse, becoming 

 gradually very coarse, dense and partially confluent laterally; 

 scutellum moderate, punctured ; elytra three-fifths longer than 

 wide, parallel and nearly straight at the sides, abruptly and 

 obtusely, ogivally rounded at apex in posterior fifth, with very 

 sparse but widely impressed and distinct punctures suturally, 

 becoming very coarse and rather close-set in regular series later- 

 ally, the lateral punctures scarcely at all muricate, the very feebly 

 defined series toward the suture somewhat impressed ; abdomen 

 finely, sparsely punctured medially. Length 7.8-8.8 mm. ; width 

 3.25-3.4 mm. Arizona (Nogales), — H. F. Wickham. 



candidum n. sp. 



Form moderately stout, parallel, polished, rufous in color throughout; 

 head coarsely and closely, somewhat irregularly punctato-cribrate, 

 the punctures generally somewhat separated, the occipital oval 

 spot well defined ; apex broadly truncate, the sides strongly con- 

 verging and moderately arcuate before the eyes ; prothorax large, 

 more transverse than in candidum^ nearly four-fifths wider than 

 long, the sides moderately arcuate, more strongly converging near 

 the apex, the basal angles right, not at all rounded but scarcely 

 prominent, the punctures rather coarsely impressed and well 

 separated medially, becoming rather rapidly very coarse, dense 

 and distinctly confluent in about lateral fifth; scutellum well 

 developed, transverse, punctured anteriorly; elytra fully two- 

 thirds longer than wide, abruptly and obtusely, ogivally rounded 

 at tip, more than three times as long as the prothorax, the punc- 

 tures in irregular series throughout the width, fine and sparse 

 suturally, coarse, more close-set and asperulate in more regular 

 series laterally, tlie series toward the suture scarcely at all im- 

 pressed ; abdomen polished though slightly rugulosc, rather finely 

 but strongly, sparsely punctured medially, evidentl\- more coarsely
