Closely allied to Trichodesma, with which it agrees in all essen- 

 tial characters, except as follows: The terminal joint of the maxil- 

 lary palpi is narrow, elongate, scarcely compressed, and pointed at 

 apex ; terminal joint of labial palpi less broadly triangular. The 

 claws are not appendiculate, but merely a little thickened at base. 

 The last ventral segment is longer, segments one, two, three and 

 five being snbequal. The vestiture is less dense and not at all tufted. 



A single species introduced from Europe is occasionally found in 

 our Southern States. 



1. N. llirtum 111. — Oblong, moderately elongate, brown, not very densely 

 clothed with short grayish and brownish recumbent hair, the latter causing the 

 elytra to appear obscurely fasciate ; the elytral intervals with a single nearly 

 regular line of slightly longer suberect recurved hairs. Head and antenna? as in 

 Trichodesma. Prothorax transverse, nearly as wide as the elytra, sides arcuate 

 and narrowed posteriorly, hind angles indistinct; surface gibbous and closely 

 granulate, a feeble impressed line from the front margin to the summit of the 

 gibbosity. Elytra with regular stripe of rather coarse, closely placed suhquadrate 

 punctures. Beneath finely grayish pubescent, sterna granulate, abdomen densely 

 finely punctate, without granules. Legs nearly as in Trichodesma, the femora 

 scarcely at all clavate. Length 4-4. b' mm. 



All native specimens seen are labeled either Louisiana or Florida. 



ANOBIOPSIS new genus. 

 Oblong, subcylindrical, clothed with rather dense recumbent pu- 

 bescence with intermixed erect hairs. Men turn transverse trape- 

 zoidal. Last joint of maxillary palpi elongate oval, pointed, very 

 little wider than the preceding joints; last joint of labial palpi 

 broadly triangular, the inner side rounded, much wider than pre- 

 ceding joints. Antennae about two fifths as long as body, 11-jointed, 

 joints 9-11 subequal to the preceding united, ninth and tenth simi- 

 lar, elongate-triangular, equal in length to sixth to eighth inclusive; 

 eleventh elongate-oval ; third joint nearly twice as long as wide, 

 fourth to the eighth each about as wide as long, the fifth slightly 

 wider than the others. Eyes moderate, rather strongly convex. 

 Prothorax strongly gibbous, narrower than the elytra. Elytra with
