MONOTOMID^E 99 



and very much longer than the last, the first, three median and the 

 fifth very differently sculptured, as usual in the genus; post-coxal 

 posteriorly angulate plaques open behind and not attaining the 

 segmental apex. Length (cf ) 1.7 mm.; width 0.5 mm. New York 

 (Catskill Mts.), H. H. Smith. Named in honor of Hendrik 

 Hudson hudsoni n. sp. 



Form slender, moderately convex, shining, piceous-black, the entire 

 elytra deep black; under surface rufo-piceous, the legs bright rufous; 

 micro-reticulation rather distinct throughout, the hairs inconspicu- 

 ous; head but very slightly narrower than the prothorax, almost as 

 long as wide, sparsely punctate, the punctures elongate, coarser and 

 closer laterally; eyes notably large; antennae very short, not longer 

 than the head, rufous, the third joint not as long as wide, the club 

 very abrupt and well developed; prothorax quadrate, as long as wide, 

 distinctly widest before apical third, where the sides are somewhat 

 angulate though very obtusely, the edges nearly even but with 

 about two serrules at the broadly rounded basal angles, the apical 

 very obtuse; surface unimpressed, with small and widely scattered 

 punctures, coarser and close on the flanks; scutellum rather large 

 and obtuse; elytra not quite one-half longer than wide and nearly a 

 third wider than the prothorax, the parallel sides evidently arcuate, 

 the apex truncate; striae fine, with small and well separated punc- 

 tures, which are broader than the striae, the flanks with a few series 

 of punctures in slightly impressed lines; pygidium moderately and 

 not densely punctate; abdomen coarsely sculptured, the punctures 

 of the first segment small, separated and elongate, those of the last 

 segment very large, oval and isolated, the foveae of the three trans- 

 verse series large, close-set and elongate; post-coxal plaques of the 

 first segment long, finely acute and entire posteriorly, not quite 

 attaining the apex. Length (9) 1.6 mm.; width 0.43 mm. A 

 single female unlabeled in the Levette collection and probably 

 taken by him in Indiana obscurum n. sp. 



Form not very slender and more depressed than in either of the preceding, 

 shining, the size minute, ferruginous, the elytra and legs slightly 

 paler, the former infumate in about apical fifth; micro-reticulation 

 feeble, coarse but obsolescent on the elytra; hairs short and incon- 

 spicuous; head much shorter than wide, evidently narrower than the 

 prothorax, with coarse but shallow, close-set punctures, becoming 

 fine and sparser apically; eyes notably large; antennae very short, the 

 third joint but little longer than the fourth and not as long as wide, 

 the outer joints of the funicle gradually a little broader; prothorax 

 very nearly as long as wide, the sides feebly arcuate, rather more so 

 near apical third and with two small spicules at the rounded hind 

 angles; surface broadly flattened medially and transversely impressed 

 subbasally, the punctures sparse, close and coarser on the flanks; 

 scutellum rather large, almost circular; elytra notably abbreviated, 

 distinctly less than one-half longer than wide, less than twice as long 

 as the prothorax and about a fifth or sixth wider, the parallel sides 

 very feebly arcuate, the apex broadly truncate; striae moderately 

 coarse, the punctures rather strong, the flanks with contiguous coarse
