rounded in apical two-fifths, two-fifths wider than the prothorax; 

 sutural stria more nearly attaining the base, the second longer and 

 stronger; foveae at basal third and just visibly behind the middle. 

 Length 1.8 mm.; width 0.7 mm. Florida (Lake Worth), Kinzel. 



fatua n. sp. 



20 Color black; body shorter and stouter, the elytra more or less evi- 

 dently rufous near the apex, the striae never punctulate 21 



Color castaneous or castaneo-testaceous; body more elongate; striae 

 sometimes punctulate 22 



21 Body stout, suboval, strongly convex and highly polished, rather 

 large in size; elytra generally with the lateral more pallid area near 

 the apex small, extremely feeble and sometimes undis/roverable; 

 under surface and legs rufo-ferruginous; head three-fifths as wide 

 as the prothorax, the strides rather long and deep; eyes moderate 

 but prominent; antennae piceous, flavate basally, two-thirds as long 

 as the elytra; prothorax large, very convex, two-fifths wider than 

 long, much wider at base than at apex, widest slightly before the 

 middle; sides broadly, strongly rounded, becoming distinctly sinu- 

 ate before the basal angles, which are right, sharp and carinulate; 

 subbasal sulcus fine, slightly punctulate laterally, broadly inter- 

 rupted, with three strong and conspicuous isolated punctures medi- 

 ally; elytra not quite one-half longer than wide, two-fifths wider 

 than the prothorax, arcuately ogival in posterior two-fifths*; sides 

 parallel, rather gradually rounding at the humeri; sutural stria not 

 quite attaining the base, the second and third strong, abbreviated, 

 a fourth and fifth stria also just glimpsible; foveae attached to the 

 inner side of the third stria at two and four sevenths. Length 2.5

 surface piceous-black, the abdominal tip black, the legs dark rufous; 

 head three-fifths as wide as the prothorax, the strioles moderate, par- 

 allel; eyes very moderate in size and prominence; antennae piceous, 

 paler basally, two-thirds as long as the elytra; prothorax two-fifths 

 wider than long, wider at base than at apex, widest at two-fifths from 

 apex, the sides very moderately rounded, becoming slightly sinuate 

 only at the sharp and subprominent basal angles; subbasal three 

 punctures coarse, deep and clearly isolated, the fine oblique sulcus, 

 from each lateral puncture to the moderate fovea, with fine and feeble 

 punctuation; carina short but strong, at a slight distance inside of 

 each angle; elytra one-half longer than wide, not quite one-half 

 wider than the prothorax, arcuately ogival in posterior two-fifths, 

 the sides rapidly rounding at the humeri; sutural stria virtually 

 attaining the base, the second and third abbreviated but rather 

 strong, the fourth and fifth distinctly visible at certain angles of 

 reflection; foveae at basal third and three-fifths. Length 2.0-2.4 

 mm.; width 0.75-0.88 mm. North Carolina (Asheville) and Penn-
