HI. simplex Lee. — Closely allied to picta and casta, but differing from both 

 in coloration, the body being rufous or rufotestaceous throughout, with the ex- 

 ception of the elytra, which are uniformly of a darker shade, the depth of color 

 varying with the maturity of the specimens, and to some extent individually. 

 The elytra are also distinctly more elongate and more parallel, and the eyes 

 larger than in either of the two species just named. The punctuation of the 

 head is very minute, agreeing nearly with picta, while the small disparity in the 

 size of the punctures of the elytral striae and intervals, also the more obvious 

 pubescence, allies it more closely with casta. Further description would he 

 scarcely more than a, repetition of the details given under picta. 



Hab. — Maryland ; Georgia; Florida (Tampa); Alabama; Texas 

 (Columbus and Brownsville); Arizona; California (Yuma, Pasa- 

 dena, Pomona, etc.). 



Simplex is thus seen to be distributed from the Atlantic to the 

 Pacific in the southern parts of our territory. An examination of 

 Zimmerman's type shows that subimpressa is a synonym of simplex 

 rather than of similata as stated by the European authors. There 

 is no doubt, whatever, that nigripennis Mots, must be similarly 

 disposed of. 



JI. villoSH Zimm. — Elongate-oval, moderately convex, rufotestaceous; the 

 elytra sometimes, or more commonly only the sutures, a little darker; pubescence 

 long and conspicuous, the hairs arising from the elytral intervals usually a little 

 more erect than those of the striae. Head rather strongly and not very sparsely 

 punctate; eyes large, apparently a little variable in size, but usually separated 

 by nearly twice their longest diameter; tempora distinct, parallel, and in length 

 about equal to one-fourth or one-fifth the length of the eye. Antennas a little 

 shorter than the head and prothorax; first joint large, subglobular ; second much 

 smaller, elongate-oval ; third to eighth narrower, subcylindrical, gradually de- 

 creasing in length, but all longer than wide; club 3-jointed, the joints increasing 

 a little in width; the ninth obconic, longer than wide: tenth obconic, about as 

 wide as long; eleventh longer, obliquely truncate at apex. Prothorax transverse, 

 sides angulate at middle, a little convergent and slightly concave posteriorly; 

 more noticeably convergent and nearly straight in front; margin obsoletely 

 creuulate, a moderately prominent denticle at the hind angles; surface rather 

 strongly punctate, the punctures distributed a little irregularly, and distant from 

 a little less to somewhat more than their own diameters; a moderately deep sub- 

 basal impression extending nearly from side to side. Elytra elongate-oval, apices 

 a little sinuate and very minutely serrulate before the sutural angles, which are 

 slightly pi - oduced ; striae not impressed, punctures moderate at base, finer poste- 

 riorly, those, of the intervals somewhat finer, though not very conspicuously so 

 as a rule. Presternum in front, and sides of metasternum somewhat sparsely 

 but strongly punctate. Abdomen finely, sparsely punctulate. Middle coxa- sepa- 

 rated by usually distinctly less than half the coxa! width. Legs moderate. (PI.

Male. — Front tibiae with longer pubescence at apex ; claw joint of front tarsi 

 dentate beneath.
