the latter two-fifths wider than long ; prothorax two-fifths wider than long, rather 

 strongly and closely punctured ; elytra three-fifths longer than wide, evenly oval, 

 a little more than three times as long as the prothorax, rather finely but deeply, 

 moderately closely and irregularly punctate ( J ). Length 2.0 mm.; width 0.85 

 mm. North Carolina ovipennis, sp. now 



Elytra not inflated and but little wider than the prothorax in either sex II 



II — Antenna; slender, about half as long as the body, the basal joint moderately de- 

 veloped and not as long as the next two combined, the third unusually elongate, 

 the club rather narrow though wider than the basal joint, the ninth not at all 

 wider than long but intermediate in width between the eighth and tenth, the 

 latter only slightly transverse ; prothorax scarcely two-fifths wider than long, 

 closely and moderately coarsely punctured ; elytra about three times as long as 

 the prothorax, rather finely but strongly, moderately closely, subseriately punc- 

 tured, the vestiture as usual {$)■ Length 2.25 mm.; width 0.85 mm. Ken- 

 tucky macra, sp. now 



Antennse stout, not quite half as long as the body, the basal joint unusually developed, 

 stout, fully as long as the next two combined, the third joint not unusually elon- 

 gate and shorter than the second, the club rather stouter, the ninth joint slightly 

 wider than long and the tenth more transverse ; prothorax shorter, more than 

 one-half wider than long, strongly, but rather less densely, punctured ; elytra 

 more than three times as long as the prothorax, rather finely but strongly, quite 

 sparsely and irregularly punctured, the pubescence rather shorter and less coarse, 

 a fifth wider than the prothorax in the male and a fourth in the female ( $ 9 )■ 

 Length 1.8-2. 1 mm.; width 0.75-0. 82 mm. Pennsylvania (Westmoreland Co.) 

 — Mr. Schmitt elongata, sp. now 



12 — Antenna; stout, the first joint rather well developed and subequal in length to the 

 next two combined, the club moderate ; prothorax rather short and transverse, 

 strongly rounded at the sides, three-fifths wider than long ; elytra slightly wider 

 than the prothorax, elongate-oval in form, fully three-fourths longer than wide, 

 the punctures rather sparse and moderately coarse ; body blackish-piceous in 

 'color ( 9 ). Length I.65-I.9 mm.; width 0.65-0.78111111. (<J9)- Pennsyl- 

 vania (Westmoreland Co.) — Mr. Schmitt obscura, sp. nov. 



Antennse and prothorax throughout nearly as in obscura, the body stouter in the female, 

 the male slender, rufo-piceous in color, the elytra scarcely two-thirds longer than 

 wide, more rapidly narrowed behind and relatively more narrowly rounded at tip, 

 the punctures coarser and more conspicuous though equally sparse and likewise 

 irregularly disposed ( 9 )• Length 1.8-2.0 mm. ; width 0.75-0.88 mm. ( $ 9 )• 

 Kentucky subf USCata , sp . nov. 



Obscura is represented by a large series displaying but little vari- 

 ability, and four others of those described above are also present be- 

 fore me in numbers sufficient to demonstrate the constancy of most of 

 the differential characters stated in the table ; the number of apparently 

 valid species is however unexpected, and, as a rule, they are remark- 

 able similar to each other in general habitus, which causes the taxonomic 

 study of them to be unusually difficult and beset with doubt. Testacca
