the fourth. The eyes are separated by scarcely one-third more 

 than their own width. The fourth joint of the maxillary palpi is 

 rather robust, the inner and outer sides making- an angle at the base 

 of nearly ninety degrees, the former about one-half as long as the 

 latter, the outer side but slightly longer than the apex which is 

 feebly arcuate. 



There is no species here described which is closely allied to this, 

 but the form of the maxillary palpi shows that it should be placed 

 in the neighborhood of quadristriata. 



I. valida Schz.— Pr. Am. Phil. Soc, XVII, 1878, p. 370.— Evenly ellip- 

 tical, convex, shining, dark ru to- testaceous throughout ; pubescence fine, 

 rather short and dense. Head small, much less than one-halt as wide as the 

 prothorax, feebly convex, broadly impressed at the base of the epistoma, finely 

 and not very densely punctate, the punctures separated by nearly their own 

 widths ; eyes very large ; antennae long and slender, filiform, nearly two-thirds 

 as long as the body, with the third and fourth joints elongate and equal. 

 Prothorax strongly narrowed from base to apex, about twice as wide as long ; 

 sides evenly rounded ; apex three-fifths as wide as the base, feebly arcuate ; 

 base transverse, the sinuations extremely feeble ; basal angles right, not 

 distinctly rounded ; disk finely but deeply punctate, the punctures distinctly 

 separated, feebly impressed just before the scutellum ; basal foveae almost 

 obsolete. Elytra nearly four times as long as the prothorax, and, at the 

 middle, about one-fourth wider, gradually and rather acutely rounded behind, 

 disk rather finely, densely punctate, with series of almost similar punctures 

 which are completely unimpressed, except the two or three sutural toward 

 apex. Abdomen finely, densely punctate ; metasternum very sparsely so ; 

 propleuraB and prosternum again more densely so. Legs slender, the first joint 

 of the hind tarsi very nearly as long as the remainder. 



Male. — Eyes separated by scarcely two-thirds of their own width ; fifth 

 ventral segment but slightly longer than the fourth, scarcely more sparsely 

 punctate, broadly subtruncate at apex and not impressed. 



Length 7.0 mm. ; width 3.3 mm. 



Florida. 



The terminal joint of the maxillary palpi is moderately wide, 

 with the inner side but slightly more than one-half as long as the 

 outer, the latter distinctly longer than the apex, the apical angle 

 distinctly rounded. 



This is one of the few tropical types which extend into our 

 fauna from Central America, where they constitute a characteristic 

 element of the genus. It is readily distinguishable by its unusually 

 large eyes and completely unimpressed elytral series.
