with the prosternum indented anteriorly and clothed with scales which 

 radiate from the central point, the coxae separated by three-fifths of 

 their width, the erect spines rather slender but very short. Length (cf ) 

 2.9 mm.; width 1.15 mm. Missouri (locality unrecorded). One 

 example. 



A distinct and rather isolated species coming near profecta, but 

 narrower and with longer, gradually more sharply attenuate elytra 

 and smaller and narrower prothorax, coarser elytral striae and 

 narrower interstrial surfaces; the beak and antennae are nearly 

 similar, differing from those of the next species. 



Centrinaspis repens n. sp. — Rather short and broadly suboval, shining, 

 black, the legs, beak and antennae rufous; upper surface with sparse 

 slender white scales, condensed and broader near outer fourth of the 

 thoracic base and also on the first three or four elytral intervals for a 

 short distance near apical third, the under surface with similar dense 

 lineiform scales on the propleura and larger, more oval, unevenly con- 

 densed scales over the hind body, the scales all white as on the upper 

 surface; beak in the female scarcely longer than the head and prothorax, 

 slender and nearly straight, rapidly arcuate and broader at base, the 

 antennae inserted slightly behind the middle, long, the first funicular 

 joint about as long as the next four, the second much more slender, 

 elongate, the club small, briefly oval, the first joint nearly half the mass; 

 prothorax almost one-half wider than long, the sides subevenly arcuate, 

 becoming gradually parallel basally, the feebly constricted apex half as 

 wide as the base; punctures rather coarse, evidently though not at all 

 widely separated, the smooth median line distinct and entire; scutellum 

 transverse, very small and rugulose; elytra but little longer than wide, 

 rapidly parabolic, slightly wider than the prothorax and three-fifths 

 longer, the apices narrowly but separately rounded; striae rather coarse, 

 very deep; intervals about twice as wide as the striae, loosely but rather 

 coarsely, feebly punctato-rugose and shining, the squamules in about 

 two lines on each; prosternum evenly convex, the coxae separated by 

 one-half their width. Length (9) 3.4 mm.; width 1.7 mm. Florida 

 (Gulfport). 



There is no other sJDecies with which this can be closely compared. 

 The shining upper surface, with rather sparse white vestiture, long 

 basal funicular joint and small oval antennal club, with the rather 

 broadly suboval outline of the body, are the most striking external 

 features. 



Centrinaspis regressa n. sp. — Rhomboidal, moderately convex, black, 

 the legs and antennae rufo-piceous; upper surface with variegated vesti- 

 ture of broad whitish scales at the sides of the pronotum and slender 

 sparser brown scales, with a few paler intermingled, over the rest of the 

 pronotal surface, broad, dark brown and very dense throughout the
