JuneiSgg] CaSEY : On AMERICAN COCCINELLID^. 143 



Male with a large, elongate, acutely triangular, feebly impressed, polished and gla- 

 brous median area of the first ventral, defined by finer and denser pubescence, the 

 fifth with a larger but rather more broadly rounded median sinus ; prothorax two 

 and one-half times as wide as long, the sides continuous in curvature, strongly con- 

 vergent, broadly and evenly arcuate, the punctures very distinct and less sparse 

 throughout than in consobrimis ; elytra quite coarsely and somewhat closely punc- 

 tured, the apical margin only extremely nanowly rufescent ; legs rather short, 

 red throughout. Length 2.3 mm.; width 1. 75 mm., Iowa (Keokuk). 



iowensis, sp. nov. 



Male with a shorter, broader and entirely unimpressed median area at the apex of the 

 first segment, the adjoining punctuation finer and closer, the fifth segment very 

 short and transverse, truncate at apex but not at all sinuate, the surface with a 

 strong transverse and anteriorly rounded impression-bevel toward apex in median 

 third or fourth ; sides of the prothorax almost continuous, strongly convergent and 

 broadly, evenly arcuate, the punctures very small, sparse and inconspicuous, 

 scarcely closer toward the sides ; elytra not very coarsely but strongly, evenly 

 and quite sparsely punctate, the apical margin very finely testaceous ; legs red 

 throughout. Length 2.2 mm.; width 1. 7 mm. Mississippi (Natchez). 



natchezianus, sp. nov. 



22 — Elytra with a wider red apical margin, this being equal in width to a fourth or 

 fifth of the length of the prothorax , .23 



Elytra only very narrowly rufous at the apical edge 25 



23 — First ventral of the male with a large median area at apex which is glabrous and 

 impunctate, but not impressed or defined by particularly dense pubescence ; fifth 

 segment very broadly and just visibly sinuato-tnincate at apex, the sinuous por- 

 tion with a very feebly convex bevel ; prothorax but little more than twice as 

 wide as long, sparsely punctulate, the sides continuous, moderately convergent 

 and evenly arcuate ; elytra quite coarsely and closely, but not densely punctate. 

 Length 1.85 mm. ; width 1.35 mm. Alabama caudalis Lee. 



First ventral of the male virtually unmodified and punctured almost throughout, the 

 fifth broadly and much more decidedly sinuate and beveled at apex ; black spot 

 of the pronotum small, not extending much beyond the middle 24 



24 — Sides of the prothorax continuous, strongly convergent, broadly and evenly 

 arcuate, the elytral punctures rather small but strong and quite sparse ; body 

 smaller and more narrowly oval, highly polished, the pubescence rather coarse 

 and sparse, easily denuded. Length 1.8 mm.; width 1.25 mm. Texas (Co- 

 lumbus) tnedionotans, sp. nov. 



Sides of the prothorax not quite continuous with those of the elytra, very much less 

 convergent, broadly and evenly arcuate ; elytral punctures coarser and more close- 

 set but not dense; body more broadly oval. Length 1.9-2.0 mm.; width 

 1. 35-1. 6 mm. Texas (Brownsville and Galveston).. . subtropicus, sp. novi 



25 — Black discal spot of the pronotum very small, not extending beyond the middle, 

 the punctures veiy sparse ; species very small, oblong-oval, the sides of the pro- 

 thorax continuous but only moderately convergent, feebly arcuate ; elytral punc- 

 tures strong, rather coarse and sparse, the pubescence whitish and coarse. Length 

 1.5 mm.; width l.o mm. Florida (Palm Beach) — Mr. F. Kinzel.
