DYNASTIN.^ 147 



teriorly; base broadly and rather distinctly lobed medially, the lobe 

 sometimes faintly sinuate medially; punctures rather strong but 

 well separated; scutellum punctured basally, often with an eroded 

 line parallel to the margins; elytra a fourth to nearly a third longer 

 than wide, very obtusely rounded at apex, barely visibly wider than 

 the prothorax, the punctures strongly impressed and widely separated, 

 uneven, the surface rather rugose suturad, the costae feeble and only 

 in part well defined and bearing rather more of the setigerous punc- 

 tures than the intervals; pygidium convex, not strongly sculptured, 

 having numerous long erect hairs; hind tarsi long, about one-half 

 longer than the tibiae. Female very much shorter and relatively 

 stouter, similarly castaneous-red in color, the head very much 

 smaller, the clypeus more rectilinearly trapezoidal, the antennal 

 club scarcely half as long as it is in the male; prothorax more rounded 

 at the sides, less lobed at base, strongly punctured, the lateral margin 

 similarly extremely fine; scutellum punctured throughout; elytra 

 barely longer than wide, the lateral edges at the middle subpromi- 

 nently rounded and narrowly but distinctly explanate, the margin 

 very thin, not at all thickened; sculpture coarser and closer, with 

 more prominent costae than in the male, the erect hairs extremely 

 sparse, shorter and scarcely noticeable, the pygidium shining, gla- 

 brous; hind tarsi very small, slender, barely longer than the tibiae. 

 Length (20 d\ i 9 ) 10.8-13.5 mm.; width 5.6-6.8 mm.; the female 

 is 10.7 by 6.5 mm. in dimensions. New York (Staten Island) and 

 Pennsylvania to Alabama. The female is rarely taken. [ Cyclo- 

 cephala villosa Burm.] villosa Burm. 



Form narrower and much smaller in size, elongate, testaceous, with erect 

 hairs; head sparsely and finely punctate; clypeus short, broadly 

 parabolic, the margin strongly reflexed; prothorax sparsely punctate, 

 somewhat narrowed anteriorly; elytra punctured in series, with 

 other smaller punctures intermingled. Length 8.7-10 mm. Geor- 

 gia. [ Cyclocephala puberula Lee.] puberula Lee. 



Form ( 9 ) narrower than in the same sex of villosa, yellow-brown in color; 

 head about two-fifths as wide as the prothorax, rufous, piceous 

 basally toward the sides as in the preceding, but with the sides 

 of the clypeus less converging from base to apex and more arcuate; 

 antennal club almost as long as the stem; prothorax rather less ab- 

 breviated, two-thirds wider than long, the sides strongly, evenly 

 arcuate, a little more converging anteriorly, the base broadly, feebly 

 lobed medially, the punctures similar; scutellum more narrowly and 

 very acutely triangular; elytra as in the female of tillosa but narrower 

 and more elongate, almost similarly but even a little more coarsely 

 sculptured, the costae distinct and convex, smooth; lateral margins 

 bristling with similar setae but with the arcuation at the middle ex- 

 tremely feeble and barely half as widely explanate as in villosa; 

 hairs of the general surface extremely short, few in number and only 

 visible apically; pygidium similar, shining, glabrous; sterna moder- 

 ately pubescent, punctate; last ventral segment longer and less 

 broadly rounded than in villosa; hind tarsi slender and very short,
