rounded at tip, the punctures fine but rather strongly impressed, moderately sparse 

 and slightly more widely separated than those of the pronotum ; antennit slender, 

 half as long as the body in the male, a little shorter in the female ; body piceo- 

 testaceous in color, shining. Length I.25-1.45 mm.; width 0.6^,-0.75 mm. 



Canada (Ottawa) curtula, .sp. nov. 



Var. A— Similar but less stout and much smaller, piceous in color, the legs and 

 antennas pale luteo-flavate, the latter slender, fully half as long as the body ; 

 eyes slightly larger, convex and well developed ; pubescence finer and a lit- 

 tle closer ; prothorax similar in form, deeply and rather acutely impressed at 

 Ijase, very finely and moderately closely punctate ; elytra very finely, feebly, 

 rather inconspicuously and moderately closely punctate, otherwise nearly 



similar. Length 1. 2 mm.; width 0.6 mm. Iowa pumilio, v. nov. 



13— Prothorax small, at its widest part not quite as wide as the base of the elytra, the lat- 

 ter less than three tunes as long as the prothorax. Body rather broadly oval, mod- 

 erately convex, polished, pale ferruginous in color throughout, the antennse slen- 

 der, not quite half as long as the body in the male, .shorter and a little stouter in 

 the female ; prothorax nearly two-thirds wider than long, angulate at the middle, 

 the sides thence to the base distinctly convergent, feebly arcuate and minutely 

 serrulate, more strongly convergent and feebly sinuate to the apical angles, which 

 are somewhat prominent, the apex distinctly narrower than the base ; disk finely 

 but deeply, moderately closely punctate, the impression along the base rather 

 deep ; elytra about one-half longer than wide, subinflated at two-fifths and nearly 

 a third wider than the prothorax, acute at tip, finely but strongly and somewhat 

 sparsely imjn-esso-punctate, the punctures at least twice as sparse as those of the 

 pronotum. Length 1.4-1.6 mm.; width 0.7-0.75 mm. New York— Mr. H. 



^- ^"^'th gonodera, sp. nov. 



Prothorax small, nearly as in the preceding but with the converging sides anteriorly 

 not sinuate and the apical angles not so acute. Body similar but shorter and 

 more convex, black or blackish in coor, the legs and antennje dark testaceous ; 

 surface polished; antennce slender, moderate in length; pronotum similarly 

 punctured and impressed ; elytra a little shorter and relatively broader, strongly 

 rounded at the sides, acute at apex, more finely and sparsely punctate. Length 



1.5 mm.; width 0.73 mm. Delaware to Florida .'...riparia, sp. nov. 



Trothorax more developed, at its widest part fully as wide as the base of the elytra, 



the latter fully three times as long as the prothorax 14 



14— Oval, moderately convex, subalutaceous in lustre, piceous, the elytra slightly 

 paler ; legs and antenna pale ; eyes rather well developed, convex ; antenna; 

 moderately slender, with the club rather stout, distinctly less than half as long 

 as the body in the female ; prothorax nearly four-fifths wider than long, the sides 

 prominently inflated before the middle, thence converging and arcuate to the base 

 and strongly convergent and feebly sinuate to the apex, the latter not more than 

 three-fourths as wide as the base ; punctures small but deep and distinct, notably 

 dense, the basal impression strong ; elytra fully three times as long as the pro- 

 thorax, widest, inflated and a fourth wider than the prothorax at two-fifths, rap. 

 idly narrowed thence to the acutely rounded apex ; punctures fine, moderately 

 close-set, twice as sparse as those of the prothorax. Length 1.6 mm.; width 

 0.72 mm. ( 9 ) Rhode Island (Boston Neck) subalutacea, sp. nov
