Prothorax much narrower than the elytra .5 



5. Pronotum rather strongly elevated along median third ; body rather 



narrow, elongate ; prothorax longer than wide, the slopes of the 

 median elevation slightly concave and devoid of tubercles, the latter

 Pronotum but feebly elevated along the middle 6 



6. Elytra oblong, about one-half longer than wide, deeply and roughly 



sculptured, with the velvety spots well developed : prothorax slightly

 tuberculose over the entire surface. Length 20.0 mm.; width 7.8 



mm. California, Cab. Levette latipennis, n. sp. 



Elytra oval, much narrower and more elongate, nearly three-fourths 

 longer than wide, scabrous as usual, the velvety spots indistinct ; 

 prothorax narrower and still more elongate, very unevenly and more

 Levette angustns, n. sj). 



The forms above enumerated are mutually very similar in facies and 

 sculpture and may prove to be subspecies of a single stock, but they are 

 at least recognizable. 



NosERUs, Lee. 



Tiie three species in my cabinet may be known by the following

1. Prothorax evenly cordate, narrowed behind from near the apex 2 



Prothorax parallel and rounded at the sides, narrowed posteriorly onlv 



behind the middle 3 



2. Body broad in form, the prothorax slightly longer than wide, scarcely 



at all convex, irregularly tuberculose and uneven, with two longi- 

 tudinal ridges, angulate toward the median line, especially evident ; 

 elytra slightly wider than the prothorax, oblong, flattened above, 

 rapidly declivous at the sides, each with three large tumidities on
