Subfamily TROPIDUCHIDA Stal. 



Of tills subfamily but two species have heretofore been recorded 

 from our territory: Tangia sponsa Uhler and Monopsis tabida Spin., 

 both from Florida, but doubtless others will yet be found along our 

 southern border. I describe below a third species which has been 

 masquerading in our collections under a false name. 



Genus PELITROPIS n. gen. 



Closely allied to Tamhinia Stal and differing principally by its wider 

 head, ecarinate front and different elytral venation. Head with the 

 eyes as wide as the pronotum or nearly so, laminately flattened. Vertex 

 produced, flat; base angularly emarginate; sides parallel; margins and 

 middle line carinate. Front almost horizontal, broad, sides parallel, 

 base angularly rounded, disk a little depressed, ecarinate. Clypeus a 

 little convex, ecarinate. Pronotum roundedly produced before, 

 deeply angularly emarginate behind; tricarinate, the lateral carinae 

 curved, almost attaining the posterior angles. Mesonotum tricarinate, 

 the lateral approximate before, the median terminating in a transverse 

 furrow before the apex. Elytra long and narrow, parallel, with a 

 very slender costal membrane; radial nervures simple; first ulnar 

 forked behind the middle, second at the middle ; claval nervures united 

 before the middle of the commissural margin, the resulting nervure 

 attaining the apex of the clavus; apex of the elytra subangularl}^ 

 rounded ; inner edge of the membrane almost rectilinear, outer curved : 

 base of membrane separated from the corium by a subangulated line 

 of transverse nervures, behind which eight longitudinal nervures run 

 straight and almost parallel to the apex; these are crossed about half- 

 way to the apex by a second series of transverse veinlets ; a few super- 

 numerary veinlets may occur on the disk either side of this second line, 

 and two short longitudinal nervures are interpolated near the inner 

 angle; apical margin with a very narrow areolate or punctate appendix. 

 Posterior tibiae trispinose. 



Tills genus is very near Tamhinia Stal from Ceylon, and in our fauna 

 should be placed near Monopsis and Tangidia. 



Pelitropis rotulata n. sp. 



Pale green obscurely varied with brown. Vertex as long as broad, 

 anterior margin obtuselv angled, almost parallel with the posterior; 

 edge carinate all around, median carina distinct, surface depressed with 

 a few lineations, most conspicuous of which are two on the middle and 

 two on either side anteriorly, placed at right angles to and touching 

 the margin. Cheeks before the eyes narrow, pointed, together with
