Baring 515 



recurved hairs and widely scattered long erect setae above, the 

 under surface wholly glabrous. The anterior coxae are widely 

 separated, the prosternum feebly impressed, the third tarsal joint 

 narrow and undilated, the claws slender and free and the antennae 

 slender, with narrow pubescent club, its first joint constituting about 

 half the mass. The species stdcatiis is very stout, with wide deep, 

 coarsely punctate and sulciform striae; the others are all much less 

 stout and have series of less coarse elytral punctures, the series 

 never more than moderately impressed. LeConte gives the 

 length of the Pennsylvania striatus as 1.8 mm. A specimen from 

 District of Columbia, which apparently represents this species, meas- 

 ures 1.65 by 0.7 mm. 



The folloAving two species are much more minute and may be 

 described as follows: 



Zaglyptus perminutus n. sp. — Smaller and more abbreviated than 

 striatus, convex, shining and castaneous; coarse matted hairs of the 

 pronotum very numerous and conspicuous; beak (cf) two-fifths as long 

 as the body, rather slender, very feebly arcuate, with the antenna? barely 

 beyond the middle, or (9), nearly half as long as the body, smoother 

 apically, the antennae at about the middle; prothorax fully a third wider 

 than long, coarsely, densely punctate, the sides converging and rather 

 strongly arcuate; scutellum as usual in the genus, minute and obtri- 

 angular, emarginate and sharply bicuspid at apex; elytra barely at all 

 longer than wide, evenly, obtusely semi-elliptic, a fourth wider than the 

 prothorax and twice as long, the serial punctures strong and rather 

 close-set, the series not impressed, except feebly toward the suture, the 

 intervals smooth and virtually impunctate. Length (cf 9 ) 1.25 mm.; 

 width 0.7 mm. District of Columbia, — Ulke. Three specimens. 



Nearly similar to striatus, but smaller and with notably shorter 

 prothorax; in striatus the more conical prothorax is but little wider 

 than long in the male. 



Zaglyptus atomicus n. sp. — Still more abbreviated than in perminutus 

 and more jjallid in color; beak in the female nearly as in that species 

 but not quite so long; prothorax shorter, nearly one-half wider than 

 long, the basally subinflated sides more constricted apically, the punc- 

 tures not quite so coarse but still denser; vestiture of coarse hairs sparser 

 and much less conspicuous, not hiding the sculpture; elytra similar in 

 form but not barely twice as long as the prothorax as in perminutus, but 

 distinctly more than twice as long as that part; punctures of the un- 

 impressed striaj distinctly coarser and less close-set than in the preceding. 

 Length (9) 1.18 mm.; width 0.65 mm. Mississippi (Vicksburg). One 

 specimen.
