Characters of Male. — (Key West, Florida.) Size very small, form stout, tegmina 

 and wings projecting well beyond apex of abdomen. Head fully as broad as long; 

 eyes very wideh' separated, abo\'e not extending inward beyond antennal bases; 

 ocelli minute, oval, with surfaces con\ex; occiput, as far \entrad as ocelli, supplied 

 with numerous minute hairs. Pronotum \ery hairy, con\ex, becoming strongly 

 so laterad; cephalic and caudal margins transverse, lateral margins divergent cau- 

 dad and weakly convex; cephalic angles very broadly rounded and very broadly 

 obtuse-angulate, caudal angles broadly rounded and subrectangulate. Scutellum 

 hairy, proportionately large. Tegmina proximad, opaque and hairy, bounded by 

 a concave line from apex of anal vein to apex of discoidal vein; remaining distal 

 portion delicate, hyaline. Wings delicate, hyaline, with two elongate, opaque 

 stigmata at costal margin, which are contiguous. Cerci with eight strongly defined, 

 rounded joints, none much longer than broad, tapering to acute apex. Supra-anal 

 plate moderately transverse, free lateral margins weakly convex, general form sub- 

 bilobate. Subgenital plate with surface convex; weakly and roundly produced 

 sinistro-distad. with apex bearing an elongate, minute style; more weakly and 

 more acutely produced dextro-distad, with apex bearing an even smaller, elongate 

 style; between these productions the distal marginal surface of the plate is nar- 

 rowly flattened, with the margin concave. 



Characters of Female. — (Key West, Florida.) Agrees with male except in the 

 following features. Somewhat larger and distinctly broader, with tegmina and 

 wings less projecting beyond the apex of the abdomen. Ocelli elliptical. Supra- 

 anal plate very weakly transverse, free margin evenly convex. Subgenital plate 

 with surface con\ex, deeply and sharph' acute-angulate emarginate in mesal quar- 

 ter, this occupied by two valves, with surfaces weakly concave, separated b>' a 

 niedio-longitudinal cleft, as in Conipsodes and suggesting a less specialized type of 

 the condition found in Homoeogamia (pi. VIII, fig. 11). Limbs and armament, 

 pulvilli and arolia, as given in generic description. 



The coloration of this species affords numerous valuable specific 

 diagnostic characters. The contrast between the sexes, in colora- 

 tion, is very great.
