DYNASTIN^E 195 



triangular; scutellum with a central fovea and some small scattered 

 punctures; elytra barely twice as long as the prothorax and but little 

 wider, distinctly swollen at the sides behind the middle, only very 

 little longer than wide and subcircularly rounded in apical two-fifths; 

 punctures moderately coarse, rather close-set and confused sub- 

 suturally and broadly toward the sides, the sutural and submedial 

 series only feebly impressed and with moderately close-set punctures; 

 pygidium with rather sparse but strong punctures, becoming still 

 sparser but only a little smaller apically; legs rather stout. Length 

 (cf 9 ) 13.0-16.0; width 7.2-9.4 mm. Texas (Dallas and Lee Co.).

8 Pronotal punctures rather coarse and more or less close-set, con- 

 spicuous. Body stout, convex, black to obscure ferruginous above, 

 much paler brownish-red beneath; head more than a third as wide as 

 the prothorax, closely rugulose, smooth at base and with some inter- 

 mediate discrete punctures; carina even, sometimes feebly sinuate 

 medially, not attaining the sides; clypeus finely, loosely rugulose, 

 more closely anteriorly, the teeth rather small ; prothorax subparallel, 

 with the sides feebly arcuate in basal two-thirds, then broadly 

 rounding and converging to the apex, the basal angles, from above, 

 obtuse but only narrowly rounded; pit varying from very small and 

 feeble to rather large, deep and partially rugulose, the tubercle 

 transversely angulate; scutellum smooth or with a few punctures, 

 sometimes having a central fovea; elytra a little longer than wide, 

 more than twice as long as the prothorax and evidently wider, 

 obtusely rounded at apex, the punctures decidedly coarse and deep, 

 rather close-set in the more or less coarsely impressed oblique series, 

 confused but even rather coarser laterad, though becoming finer on 

 and near the apical declivity, rather few in number but coarse on 

 the subsutural interval; pygidium with small and very sparse 

 punctures, becoming less sparse and intermingled with more or less 

 fine rugulosity basally and laterally. Male shorter and relatively 

 stouter than the female. Length (15 cf, 12 9) 12.7-15.0 mm.; 

 width 7.3-9.0 mm. New Jersey and North Carolina to Louisiana 

 (Vowell's Mill), Iowa and Kansas (McPherson). [Scarabccus 

 gibbosus DeG., Geotrupes juvencus Fabr., Podalgus variolosus Burm., 



and Bothynus morio Lee.] gibbosus DeG. 



A Similar to gibbosus in nearly every way but a little less stout, and 

 except that the thoracic punctures are more close-set and the 

 pygidium (cf ) shorter, rather broader, more convex, more broadly 

 rounded at apex and having everywhere rather coarse, more or less 

 close-set and conspicuous punctures; hind tibiae much stouter. 

 Length (d 71 ) 13.8 mm.; width 8.0 mm. Mississippi (Vicksburg).
