gradually rounded behind; striae deep but not very coarse; intervals 

 between two and three times as wide as the striae, each with a single 

 line of very distinct, not very small though shallow, moderately 

 separated punctures; prosternum impressed along the median line. 

 Length (cf) 2.65 mm.; width i.o mm. North Carolina (Southern 

 Pines),— Manee erebea n. sp. 



Prothorax relatively smaller, much narrower than the elytra 30 



30 — Form oblong, moderately convex, deep black; beak (cf ) stout, feebly 

 arcuate, strongly sculptured and as long as the prothorax, or (9 ), 

 more slender, feebly arcuate, nearly but not quite smooth and fully 

 as long as the head and prothorax; antennae at four-sevenths (cf ) 

 or at the middle (9 ); prothorax a sixth (d^) or a fifth (9 ) wider 

 than long, the sides feebly converging and broadly, subequally 

 arcuate, the very short subtubulate apex three-fifths as wide as the 

 base; punctures fine, sparse, the smooth line not entire; surface 

 alutaceous; elytra shining, a third to two-fifths longer than wide, a 

 fourth wider than the prothorax and much more than twice as long, 

 parallel and nearly straight at the sides, rounding rapidly in about 

 apical third; striae moderate, the intervals about three times as wide 

 as the grooves, each with a single series of minute but evident, 

 remotely spaced punctures. Length (cf 9) 2.4-2.6 mm.; width 

 0.85-1. 1 mm. Southern Illinois and Missouri (St. Louis). Five 

 examples amnicola n. sp. 



Form oblong, more shining throughout, deep black; beak (9) only 

 moderately slender and distinctly sculptured, feebly arcuate and as 

 long as the head and prothorax, the antennae at about the middle; 

 prothorax small, between a fourth and third wider than long, the 

 sides parallel, rounding beyond the middle to the tubulate apex, 

 which is three-fifths as wide as the base; punctures fine and sparse, 

 the smooth line distinct; elytra more elongate, fully one-half longer 

 than wide, more than a fourth wider than the prothorax and two 

 and two-thirds times as long; sides parallel and straight, obtusely 

 rounded in about apical half; grooves fine but deep; intervals four 

 times as wide as the grooves, each with a single series of extremely 

 minute and feeble, well separated punctures, invisible except under 

 careful observation. Length ('9 ) 2.5 mm.; width 0.9 mm. North 

 Carolina (Southern Pines), — Manee nanella n. sp. 



31 — Body elongate-suboval, rather convex, somewhat shining, deep 

 black; beak in the male short, not quite as long as the prothorax, 

 moderately thick, not very densely sculptured and just visibly 

 arcuate, the antennae at three-fifths; prothorax a fifth wider than 

 long, the sides converging and feebly, evenly arcuate from base to 

 the tubulate apex, which is three-fifths as wide as the base; punc- 

 tures fine and rather sparse; elytra oblong, two-fifths longer than 

 wide, a fourth wider than the prothorax and two and one-half times 

 as long, parallel, gradually rounded behind the middle; striae moder- 

 ate, deep; intervals rather more than three times as wide as the 

 grooves, each with a single series of minute but evident, remotely 

 spaced punctures; male abdomen moderately impressed at the
