testaceous, moderate, the medial joints two and one-half times as 

 long as wide; prothorax widest but slightly before the middle, the 

 sides strongly, subprominently rounded, less arcuate anteriorly and 

 posteriorly, becoming sinuate only slightly before the hind angles, 

 which are right; base two-thirds the maximum width; impressions 

 subobsolete, the stria very fine; foveae small, deep, linear, separated 

 from the very short fine carina; elytra oblong, gradually rounded 

 behind, slightly more than one-half longer than wide, two-fifths 

 wider than the prothorax, the striae not fine, scarcely at all impressed, 

 the distinct and close-set punctures continuing to about apical third; 

 foveae near basal and apical third. Length (d 71 9 ) 4.5-4.7 mm.; 

 width 1.7-1.75 mm. New Jersey to Texas (Galveston). 



constrictum Lee. 



A Similar to constrictum but stouter, the prothorax broader and still 

 more strongly rounded at the sides but in similar manner, except 

 that basally they become only just visibly sinuate at the hind 

 angles, which are obtuse, with the apex minutely and feebly prom- 

 inent; elytra uniformly deep black, excepting the pale areas, which 

 are as in constrictum. Length (9 ) 5-O mm.; width 1.9 mm. New 



Jersey vernula Csy. 



B Similar to constrictum but narrower, the eyes not quite so large 

 but more prominent, the prothorax shorter, one-half wider than 

 long, widest rather more anteriorly and with more evenly rounded 

 sides, similar at the angles; foveae longer, feebler and more irreg- 

 ularly impressed; elytra similar but narrower, the foveae nearer 

 two and four sevenths, the lustre rather more aeneous. Length 

 (9) 4.4 mm.; width 1.65 mm. Texas (Brownsville), Wick- 

 ham civile n. subsp. 



Body larger and more elongate, similar in coloration and lustre, the ab- 

 domen rufous only at tip and the legs darker rufous; head not over 

 three-fourths as wide as the prothorax, the sulci rather broad and 

 shallow; antennae fusco-testaceous, not much over two-thirds as 

 long as the elytra, the medial joints as in constrictum; prothorax 

 not quite one-half wider than long, the sides more evenly rounded 

 to the short parallel basal part, the angles right and sharp, 'the base 

 oblique at the sides, barely tw r o-thirds the maximum width; surface 

 and foveae nearly as in constrictum, the carina fine but distinct; ely- 

 tra parallel, very gradually parabolic behind, almost three-fifths 

 longer than wide, colored as in constrictum, the lateral fascia near 

 basal third extremely faint and nubilous, the posterior marking dis- 

 tinct; striae rather fine, scarcely impressed, obsolescent well before 

 the tip, the punctures rather small and well separated, except in 

 the two inner series, the foveae near basal and apical third. Length 

 (9 ) 5-5 mm.; width 2.0 mm. Arizona (probably southern). 



particeps n. sp. 



64 Form elongate-oval, rather convex and shining, the anterior parts 

 slightly alutaceous, black, often with feeble aeneous lustre; elytra 

 with the pale apex and external small connected spot feebly defined 

 and rather faint; eighth interval with a long and very faint submedian 

 streak; under surface black, the abdomen obscure rufous, the legs
