Second antennal joint obviously longer and thicker than the third; body 

 mnch smaller and more slender, the elytra In great part pale flavate in 

 color 9 



9 — Strigilation of the under surface of the head obsolescent, the surface 



smooth and polished, with a few deep punctures between the gular 

 sutures anteriorly, dark piceous to nearly black, the head deep black, 

 the elytra pale flavate, clouded with piceous on the flanks and in nearly 

 apical half; legs pale, the antennae dark rufous; head rather short, 

 behind the antennae not or but slightly longer than wide, the sides 

 straight and feebly converging, — in opposition to the general rule — 

 from the eyes to the rounded basal angles; punctures moderately coarse, 

 deep, sparse toward the sides but closer near the eyes, the post-ocular 

 flattened line much narrower than usual, distinctly punctured ; punc- 

 tures of the under surface fine but strong, sparsely and uniformly scat- 

 tered though narrowly obsolete along the sutures; prothorax elongate 

 and evidently narrower than the head, the sides feebly diverging from 

 the obtuse and slightly rounded apical angles for a third of the length, 

 then moderately converging and feebly sinuate to the base ; punctures 

 of the dorsal and sublateral series rather feeble and only about seven in 

 number; a few coarse punctures along the edge at the apical angles are 

 also visible, the entire surface, as well as that of the head, having very 

 minute, sparsely but evenly distributed punctules as in the genus 

 Nudobius, the surface feebly tumid in the middle at base; elytra 

 elongate, much wider than the prothorax and not quite as long, wider 

 tkan the head, the punctures strong though sparse, the two close-set 

 medial series only distinct in basal half; abdomen very minutely and 

 sparsely punctulate. Length 5.8 mm.; width 0.7 mm. New York 



(Hudson Valley) gilripennig n. sp. 



Strigilation distinct, the space between the gular sutures anteriorly finely and 

 roughly sculptured but scarcely punctured, blackish -piceous in color, the 

 elytra thinner and more diaphanous than usual, paleflavous, feebly infu- 

 mate at base and thence gradually more narrowly along the suture to be- 

 hind the middle; legs pale, the antennae very dark testaceous; surface 

 polished, without fine scattered punctules ; head moderate, behind the an- 

 tennae bat little longer than wide, more or less distinctly infiated toward 

 base, the angles broadly rounded; punctures rather coarse, deep and 

 close-set toward the sides, the under surface, post-ocular flattened line 

 and pronotal sculpture nearly as in hamatus, the latter, however, with 

 fewer extra-serial punctures anteriorly; prothorax elongate, very 

 slightly narrower than the head, the sides distinctly converging from 

 near the apex to the base and virtually straight; elytra somewhat elon- 

 gate, a little longer than the prothorax and much wider, finely but 

 distinctly, somewhat sparsely punctured nearly as in hamatus, the two 

 medial series traceable almost to the apex; abdomen finely, sparsely 

 punctulate toward the sides. Length 3.6-5.3 mm.; width 0.6-0.8 mm.
