Baring 397 



elytra, excepting a dense whitish streak behind the scutellum and some 

 sparse isolated pale scales elsewhere; on the under surface throughout 

 rather small, more oval, luteous and close though perceptibly separated; 

 beak in the female thick, evenly and moderately arcuate, cylindric and 

 scarcely as long as the head and prothorax, the antennae inserted at the 

 middle^ the basal funicular joint long but notably thick, the club rather 

 elongate-oval; prothorax three-sevenths wider than long, the sides con- 

 verging, evenly and moderately arcuate throughout, the apex uncon- 

 stricted and fully half as wide as the base; punctures rather coarse and 

 close-set; elytra at the swollen humeri markedly wider than the pro- 

 thorax, not quite twice as long, only a fifth longer than wide, rapidly 

 parabolic, with narrow apex; striae deep and abrupt, clearly defined, the 

 intervals uniformly and densely clothed and between three and four 

 times as wide as the striae; anterior coxae separated by a little less than 

 half their width. Length (9) 2.7 mm.; width 1.25 mm. Mississippi 

 (Warcloud). One example. 



This species is allied to perscita Hbst., but not very closely; it 

 is stouter, the outline more evenly rhomboidal; the prothorax 

 is relatively smaller and evenly and arcuately narrowed from base 

 to apex and not more rapidly narrowed apically as in that species; 

 the elytra are broader, the integuments blacker, the condensation 

 of pale scales at the sides of the pronotum broader, the small con- 

 densation of paler scales at the base of the third interval— distinct 

 in perscita — altogether wanting, and the pale scattered scales, which 

 are scarcely observable in that species, are very conspicuous. The 

 beak is still shorter. My representatives of perscita are from New 

 Jersey and Indiana. 



Centrinaspis connivens n. sp. — Rather broadly, obtusely oval, obscure 

 rufous, clothed above densely with broad whitish scales, replaced by 

 narrower and less dense, pale fulvous squamules in median three-fifths 

 of the pronotum and on the elytra, except behind the scutellum, at the 

 humeri, at base of the third interval, at a point on the fourth interval at 

 the middle and to some extent broadly toward the sides; under surface 

 with well separated whitish scales, denser at the posterior end of the 

 met-episterna and closer and more linear on the propleura; beak in the 

 male short, thick, cylindric and evenly arcuate, as long as the head and 

 prothorax, the antennae short, inserted at the middle, the club oval, as 

 long as the preceding six joints; prothorax large, three-fifths wider than 

 long, with converging and evenly arcuate sides from base to apex; 

 punctures close-set; scutellum rather large, flat, squamulose and trape- 

 zoidal; elytra broadly parabolic, barely longer than wide, slightly wider 

 than the prothorax and about twice as long; striae deep, not concealed; 

 intervals varying from more than two to over three times as wide as the 

 striae; prosternum (cf) with two short erect spines and a deep rounded 

 pit between them, the coxae separated by slightly less than their own
