short fine and rather sparse but evenly distributed vestiture. Legs short and 

 robust, strongly punctato-rugulose, very sparsely clothed with short fine hairs. 

 Length 8.2 mm. ; width 2.5 mm. 



Florida. 



Rather closely related to placidus, but slightly smaller and more 

 slender, and readily distinguishable by the coarser pronotal punc- 

 tuation, the more marked scutellar impression, and, especially, by 

 the nature of the submarginal vitta which is here narrow and 

 extremely dense ; in placidus the vitta is nearly twice as wide, and 

 formed of pubescence which is much less densely placed, not con- 

 cealing the punctures of series seven to nine which traverse it. 



In placidus ten series of punctures can easily be counted on each 

 elytron, while in amplexus there appear to be but nine. 



7 Li. oregonilS n. sp. — Moderately robust, convex, elongate-oval ; body, 

 beak and legs black, the antennae dark rufo-testaceous ; integuments polisbed 

 throughout, the vestiture very dense and moderately long in the lateral vitta 

 of the pronotum and elytra, elsewhere very short and sparse, forming a broad 

 subsutural and narrow median vitta on each elytron, and rather broadly de- 

 nuded near the lateral vitta and along a narrow median line on the pronotum. 

 Head finely, sparsely punctate, with a small interocular fovea; beak short 

 but rather slender, scarcely more than three-fourths as long as the prothorax, 

 cylindrical, nearly glabrous, very finely, sparsely punctate, the scrobes ex- 

 tending but slightly beyond the middle. Prothorax slightly wider than long, 

 the apex truncate, the base broadly, not strongly angulate in the middle ; 

 sides rather strongly convergent from base to apex, feebly arcuate, slightly 

 swollen near apical third ; disk finely, rather densely punctulate and with 

 rather coarse, somewhat sparse punctures. Elytra not more than twice as long 

 as wide, scarcely perceptibly wider than the prothorax, somewhat obtusely 

 rounded at apex; sides parallel and nearly straight; disk feebly flattened 

 near the scutellum and also with a small intrahumeral impression, having 

 completely unimpressed series of somewhat coarse and rather distant punc- 

 tures, which become much finer toward apex, the intervals excessively 

 minutely, not densely punctulate. Abdomen rather densely clothed with 

 longer pubescence which becomes very dense along the sides. Legs short, 

 rather robust, sparsely pubescent, the femora witli a small spot of dense white 

 pubescence near apical third. Length 7.0 mm. ; width 2.4 mm. 



Oregon. 



Represented by a unique specimen of undetermined sex, very 

 kindly given me by Mr. W. Julich. Although belonging near 

 placidus, oregonus is immediately distinguishable by the peculiar 

 arrangement of the elytral vestiture, the unimpressed and more 

 transverse prothorax and small size.
