in the adult condition over this region. In this material the gen- 

 eral coloration is rich blackish red-brown. 



Characters of Male. — (Miami. Florida.) Head large, eyes widely separated, ver- 

 tex rounding evenly into face, which is weakly convex, vertex with three weakly 

 defined, perpendicular sutures, these often obsolete, pale ocellar spots usually suf- 

 fused, a larger pale spot usually present below the antenna! sockets on the genae. 

 Maxillary palpi small; fourth joint distinctly shorter than third, fifth (distal) joint 

 distinctly shorter than fourth. Dorsal surface polished; pronotum and metanotum 

 microscopically punctulate, tegmina cribroso-punctulate, abdomen weakly punctu- 

 late becoming shagreenous distad. Pronotum not strongly convex, this convexity 

 slightly the greatest medio-longitudinally; cephalic margin ver\- weakly convex, 

 with surface there also weakly convex ventrad, rounding evenly into lateral mar- 

 gins, which are moderately convex and divergent to caudal angles, which are mod- 

 erately sharply rounded, the lateral and caudal margins there forming an angle 

 appreciably less than a right-angle; caudal margin very weakly convex, nearly 

 straight. Tegmina subquadrate, extending just beyond caudal margin of mesono- 

 tum; the sutural margins slightly overlapping, or separated by a space of over 2 

 mm.; costal and sutural margins very weakly convex and subparallel, the former 

 cingulate; distal margin transverse, truncate, occasionally briefly, weakly and 

 roundly {produced at the external angles. Wings absent. Latero-caudal angles of 

 fourth to sixth dorsal abdominal segments produced, in increasing ratio caudad. in 

 slender, sharp, elongate teeth. Supra-anal plate decidedly transverse; lateral 

 margins weakly converging distad, distal margin broadly obtuse-angulate emargi- 

 nate and decidedly hairy, margin of plate, at rather sharply rounded latero-caudal 

 angles, supplied with microscopic, stout, sharp spines; ventral surface of plate 

 thickly studded with such spines. Cerci rather short, with (about ten) weakly 

 defined joints, tapering distad to acute apex; dorsal surface deplanate, ventral sur- , 

 face convex, with lateral margins \ery narrowly and weakly flattened. Genital 

 hook situated sinistro-ventrad in anal chamber, an elongate, slender, flattened, 

 chitinous process which projects caudad, proximad it is horizontally flattened, dis- 

 tad obliquely flattened, there directed dextrad, narrowing and curving toward the 

 apex which is enlarged, flattened, with distal portion feebly produced, convex in 

 outline except ventral margin which is straight, the apex at this margin narrowly 

 produced in a sharp projection. The anal chamber is filled proximad with a com- 

 plexity of lobiform processes, in large part chitinous, from which project mesad two 

 short, sharp, chitinous spikes and a single subchitinous, slightly longer process 

 curved dorsad; dextrad of these an elongate, slender, chitinous process, as long as 

 the genital hook, tapers and curves gently dextrad to its aciculate apex. Sub- 

 genital plate transverse, strongly emarginate meso-laterad, at which points on the 

 margin, in soft sockets, are situated symmetrical, rather stout, very elongate styles, 

 which taper evenly to their acute apices, mesal half of plate produced with margin 

 broadly convex. Limbs and armament of same as given in generic description. 



Characters of Female. — (Miami, Florida.) Agrees with male in aml)isexual char- 

 acters, difl'ering in the following features. Supra-anal plate more produced; lateral
