Baring 499 



throughout and without trace of the condensation of white scales 

 broadly along the sides of the hind body beneath. The male has 

 the prosternum similarly unarmed, except in cases to be mentioned 

 below, but, anteriorly, there is a deep fossa and the prosternal 

 surface is devoid of the conspicuous clothing of pale scales to be 

 noted in Haplostethops; the female seems to be similarly smaller 

 than the male. The genus is widely distributed over the Atlantic 

 states, and the species now at hand may be known as follows: 



Pronotum coarsely sculptured; prosternum spinose or tuberculate before 



the coxae 2 



Pronotum finely and in general more densely sculptured, the body very 

 much smaller in size, except in dispersus; prosternum never armed 



in the male 9 



2 — Punctures of the strial intervals small though distinct . 3 



Punctures rather coarse and relatively conspicuous 7 



3 — Pronotum coarsely punctate, the punctures isolated basally but else- 

 where generally confluent in short longitudinal rugae, especially 



toward the middle 4 



Pronotum deeply, longitudinally rugose throughout; body less broadly 



oval 6 



4 — Apical tubulation of the prothorax notably long and clearly defined. 

 Body broadly suboval, strongly convex, shining, black throughout 

 and virtually glabrous, the squamules of the elytral series very 

 small and barely discoverable; beak in the female much longer than 

 the head and prothorax, moderately sculptured and arcuate; an- 

 tennae at the middle; prothorax two-thirds wider than long, the 

 sides strongly converging and straight, rounding before the middle 

 to the strongly tubulate apex, which is less than half as wide as the 

 base, the tube between a fifth and sixth as long as the entire pro- 

 notum; punctures isolated basally though generally more or less 

 confluent longitudinally, the median smooth line very narrow but 

 subentire, the scutellum small, emarginate behind; elytra broadly 

 ovoidal and convex, a third longer than wide, much wider than the 

 prothorax and two and one-half times as long; grooves rather coarse; 

 intervals not quite twice as wide as the grooves, the punctures uni- 

 seriate and only moderately separated; under surface strongly 

 punctured, rather densely on the abdomen. Length (9) 3.5 mm.; 

 width 1.75 mm. Pennsylvania (Allegheny), — Hamilton, [Id. 



strigapunctus Ham.] tubulatus Say 



Apical tubulation very short and barely noticeable 5 



5 — Form very stout, ovoidal and convex, polished and deep black; 

 beak (cT) much longer than the head and prothorax, evenly and 

 moderately arcuate, strongly sculptured, the antennae near three- 

 fifths, or (9), shorter, thick, similar to that of the male but less 

 sculptured, the antennae near the middle; prothorax almost as in 

 tubulatus, except that the apical tubulation is very short, not half 

 as wide as the base; elytra almost as in tubulatus, except that the
