144 MEMOIRS ON THE COLEOPTERA 



Female smaller, stouter, darker in color, inflated posteriorly; head 

 much smaller, the eyes not so large, the clypeus shorter; prothorax 

 shorter and more strongly punctate, three-fourths wider than long; 

 elytra shorter, but little longer than wide, behind the middle much 

 wider than the prothorax, with the edge broadly arcuate and slightly 

 thickened ; punctures much coarser, the geminate series more distinct ; 

 pygidium finely, sparsely punctate, glabrous; hind tarsi much shorter, 

 scarcely longer than the tibiae; antennal club three-fifths as long as 

 in the male. Length (cf 9 ) 11.0-12.3 mm.; width 5.9-6.4 mm. 

 Florida. Four examples * parallela n. sp. 



Body oblong-oval in form, the prothorax always somewhat narrower than 

 the elytra in both sexes 4 



4 Prothorax less transverse, three-fifths to two-thirds wider than long 

 in both sexes. Body (cf) elongate-oval, convex, shining, rather 

 dark and piceo-flavate in color, moderately shining; head black, half 

 as wide as the prothorax to somewhat more, not coarsely but strongly, 

 rather loosely punctate, finely and sparsely toward base; eyes 

 separated by distinctly more than twice their width; clypeus rufous, 

 not quite twice as wide as long, trapezoidal, the sides nearly straight; 

 angles obtuse but not very broadly rounded, the apex feebly arcuate, 

 moderately reflexed, the surface irregularly, shallowly and not very 

 densely punctate; antennal club slender, nearly one-half longer than 

 the stem; prothorax with the sides feebly, subevenly converging and 

 broadly arcuate from the rounded basal angles to the apex; punctures 

 rather strong but sparse, somewhat less sparse laterally; scutellum 

 sharply ogival, punctured toward base and with a more or less evident 

 groove parallel to the margins; elytra nearly a fourth longer than 

 wide, distinctly wider than the prothorax, feebly swollen posteriorly, 

 circularly rounded at apex, rather strongly but loosely punctate, 

 the three geminate series more or less evident and feebly costulate; 

 pygidium convex, rather strongly, loosely punctate and with moder- 

 ate erect pubescence. Female shorter, more oblong-oval, pale red- 

 brown, the head smaller, more finely punctate, with a smooth 

 median line, the eyes not quite so large, the clypeus almost exactly 

 as in the male; prothorax almost as long but broader and with more 

 arcuate sides; elytra almost similarly but more coarsely sculptured, 

 the edges at the middle distinctly dilated, rounded and very much 

 thickened. Length (6 cf, i9) 9-5-13-5 mm.; width 5.5-6.8 mm. 

 Alabama (Huntsville and Mobile) and Louisiana (Morgan City and 

 Vowell's Mill) protenta n. sp. 



Prothorax shorter, more parallel basally, the body more oblong-oval in 

 form 5 



5 Prothorax only about three-fourths wider than long, head large, rather 

 evidently more than half as wide as the prothorax. Body larger than 

 in any other of this section, oblong, rather convex and shining, pale 

 yellow-brown; head black, the clypeus rufous, sculptured nearly 

 as in the preceding, the eyes larger and more prominent, separated 

 by twice their own width to a little more; clypeus almost semicircular, 

 the angles at the sides of the feebly reflexed and rounded apex barely 

 observable; suture effaced medially; antennal club barely at all
