Baring 481 



porrect prosternal spines slender, shorter than in confusa. Length 

 (cf) 3.3 mm.; width 1.2 mm. Illinois (southern)., .illiniana n. sp. 



6 — Prothorax nearly as long as wide 7 



Prothorax much more abbreviated, distinctly shorter than wide 8 



7— Body small, elongate-oval, convex, feebly shining; beak notably 

 short in both sexes, dull and sculptured, nearly straight, but arcuate 

 apically (cJ"), or very slender, slightly and evenly arcuate and nearly 

 smooth (9), the antennae at four-sevenths (cf) or slightly behind 

 the middle (9); prothorax with the sides feebly converging, grad- 

 ually a little more arcuate apically, the feebly constricted apex 

 much more than half as wide as the base; punctures moderately 

 close-set and distinct, the median smooth line not quite attaining 

 the apex; basal lobe short and broadly rounded; scutellum small, 

 nude as usual; elytra parabolic, a little wider than the prothorax 

 and about twice as long; grooves moderate but deep, not crenulate, 

 the intervals twice as wide as the grooves to somewhat less; pro- 

 sternum of the male with a narrow anterior fossa, devoid of any 

 trace of spines, the abdomen with rounded basal impression. Length 

 (cf" 9) 2.2-2.4 mm.; width 0.9-1.1 mm. Florida (Enterprise). 



Five specimens fraterculus Csy. 



' Body larger and stouter, more oblong-oval and less convex, subaluta- 

 ceous; beak in both sexes nearly as in the preceding; prothorax 

 larger and broader, not quite so nearly as long as wide, the sides 

 similar, the more distinctly tubulate apex slightly more than half 

 as wide as the base; punctures and smooth median line similar; 

 elytra much broader, more ovulate, with similarly very feeble 

 humeral prominences, distinctly wider than the prothorax and about 

 twice as long; grooves, intervals and sculpture nearly similar, the 

 slender setiform squamules more numerous; prosternum of the male 

 with a very deep circular pit and two slender and well developed 

 porrect spines, the abdomen more acutely and narrowly impressed 

 at the middle of the rather strongly punctured first segment. Length 

 (cf 9) 2.6-2.8 mm.; width 1.15-1.25 mm. Florida, Alabama and 



New Jersey (Newark). Seven specimens difl&dens n. sp. 



Body more narrowly oval and rather more convex, feebly shining; beak 

 in the male short, not as long as the prothorax, moderately thick, 

 more shining and less closely punctate than usual in that sex, similar 

 in form to that of the preceding and with similar small dorsal 

 tumidity adjoining the feeble transverse impression of the head; 

 prothorax as long as wide, longer and narrower than in diffidens, the 

 sides gently rounding, becoming straighter and subparallel behind 

 the middle, the subtubulate apex narrower, not more than half as 

 wide as the base; punctures somewhat more separated, the smooth 

 median line biabbreviated; elytra narrower and with the similarly 

 feebly oblique sides less arcuate, distinctly wider than the prothorax 

 and not quite twice as long, the subuniserial to confused punctures 

 closer and evidently stronger; intervals twice as wide as the grooves 

 to distinctly less; male with prosternal porrect spines and deep 

 perforate fovea, the deep niedio-basal impression of the abdomen
