subevenly arcuate, strongly converging in apical fourth to the long 

 tubulate apex, which is distinctly less than half as wide as the base; 

 punctures not very coarse but deep and close-set, longitudinally 

 rugose laterally, with a small elongate vacant spot at each side near 

 outer fifth, the smooth median line only visible centrally; scutellum 

 quadrate, impressed along the middle and more emarginate behind 

 than in the preceding species; elytra three-fifths longer than wide, 

 somewhat narrower than the prothorax and barely twice as long, 

 with moderate humeral callus; sides subparallel and feebly arcuate, 

 gradually more arcuate behind to the broadly obtuse and circularly 

 rounded apex; grooves deep and abrupt, not at all crenulate; 

 intervals three times as wide as the grooves, with fine and rather 

 close-set but loosely confused punctuation. Length (cf') 4.2 mm.; 

 width 1.72 mm. North Carolina (Southern Pines), — Manee. 



inflaticollis n. sp. 



Form oblong, more parallel, convex, black, the elytra feebly picescent, 

 the legs and antennae piceo-rufous, moderately shining, the elytra 

 subalutaceous, the fine sparse squamules distinct, alternately con- 

 fused and in nearly single line on the elytra; beak in the male 

 thick, strongly sculptured, straight in basal, arcuate in apical, half, 

 as long as the head and prothorax, the antennae at four-sevenths; 

 prothorax fully a third wider than long, the sides parallel, evenly 

 and rather strongly arcuate, very abruptly, subtransversely rounded 

 anteriad to the long tubulate apex, which is fully half as wide as the 

 base; punctures not very coarse but strong, very close-set, less so 

 basally, larger and more impressed laterally, the median smooth 

 line distinct; entire surface notably convex as in the preceding; 

 scutellum quadrate, impressed along the middle; elytra equal in 

 width to the prothorax and more than twice as long, fully three- 

 fourths longer than wide, the humeral callus only moderate but 

 evident; sides feebly converging and broadly arcuate, gradually 

 more arcuate behind to the obtusely but not very broadly rounded 

 apex; grooves deep, sharply defined, not at all crenulate; intervals 

 alternating, two to three times as wide as the grooves; punctures 

 numerous, strong, confused on the third and fifth, densely so basally, 

 in uneven single line on most of the others; male with the abdomen 

 impressed medially toward base, the anterior coxae separated by a 

 third their width. Length (cf) 4.3 mm.; width 1.7 mm. Penn- 

 sylvania rotundicollis n. sp. 



7 — Body elongate and rather narrow, subcylindrically convex, black 

 throughout, the sparse, minute and setiform squamules everywhere 

 very indistinct; beak nearly similar in the sexes, deeply sculptured 

 and rather thick, barely as long as the head and prothorax (cf ), a 

 little longer (9), almost straight, the antennae slightly beyond the 

 middle in both sexes; prothorax but slightly wider than long, the 

 sides just visibly converging and feebly subsinuate, rounding rapidly 

 in apical third to the broad tubulate apex, which is two-thirds as 

 wide as the base; punctures very moderate and shallow, rather close- 

 set, sparser basally, the smooth line subobsolete anteriorly; scutel- 

 lum quadrate, not canaliculate; elytra twice as long as wide, evi-
