of the usual form, very minutely, densely punctulate and rather 

 strongly, more sparsely so beneath; antennae obviously shorter than 

 the head and prothorax, the latter slightly longer than wide and usually 

 but little narrower than the head, the sides subparallel or very feebly 

 convergent from the obtuse and slightly rounded angles at apical fourth 

 or fifth, the punctures less dense than those of the head; elytra not or 

 but very slightly longer than wide, much wider than the head, parallel, 

 about a fourth wider but only just visibly longer than the prothorax; 

 gular sutures well separated. Length 2.4 mm.; width 0.4 mm. Rbode 

 Island and New York (Hudson Valley; exlgnus Er. 



Body resembling exiguus in coloration but smaller and rather more slender, 

 alutaceous as usual, the punctures of the under surface of the head 

 smaller and feebler; head, antennae and prothorax nearly similar, the 

 elytra however relatively much narrower and only just visibly wider 

 than the head, parallel, quite distinctly longer than wide, scarcely 

 more than a sixth wider and but slightly longer than the prothorax, 

 sculptured as usual. Length 2.3 mm.; width 0.35 mm. North Caro- 

 lina (Asheville) macileutns n, sp. 



Body somewhat resembling the two preceding in form and sculpture but 

 with the prothorax relatively narrower and more elongate; color pale 

 flavo-testaceous throughout, the head but slightly, and the abdomen 

 not at all, darker; head well developed, of the usual form; prothorax 

 much narrower than the head and more shining, fully a fifth longer 

 than wide, the sides behind the obtuse and rather broadly rounded 

 angles at about apical fifth subparallel; elytra parallel, only very slightly 

 longer than wide, but slightly though obviously wider than the head, 

 fully a third wider but only just visibly longer than the prothorax. 

 Male unknown. Length 2.3 mm.; width 0.38 mm. New York (Hud- 

 son Valley") degener n. sp. 



16 — Coloration as in exiguus; form parallel, the lustre alutaceous, the 

 pronotum more shining as usual ; head distinctly elongate, the eyes 

 larger than usual and situated at obviously less than twice their own 

 length from the base; prothorax much narrower than the head and 

 distinctly elongate, the sides very feebly converging behind the obtusely 

 rounded angles at apical fifth and nearly straight; elytra obviously 

 though not greatly wider than the head, nearly a fifth longer than wide, 

 parallel, about a fourth wider and slightly longer than the prothorax; 

 gular sutures well separated as in the three preceding species. Male 

 unknown. Length 1.8 mm.; width 0.3 mm. North Carolina (Asheville).

17 — Slender, parallel, rufo -testaceous, the elytra and abdomen fuscous, 

 the former with the suture narrowly and indefinitely paler; antennae 

 and legs pale; lustre alutaceous, the pronotum more shining; head 

 slightly longer than wide, of the usual form, densely punctulate; pro- 

 thorax narrower than the head, a little longer than wide, with the sides 

 behind the strongly obtuse and rounded subapical angles parallel; 

 eljtra about a fourth longer than wide, distinctly wider and slightly 

 longer than the prothorax, sculptured as usual. Sixth ventral in the 

 male rather deeply, triangularly emarginate, the emargination as wide
