The references and synonymy for the present species are given 

 by Rehn and Hebard in May, 1914, to that date. The generic 

 name there proposed was preoccupied by Wattenwyliella Carl, 

 described in April, 1914. The species has, in past Hterature, been 

 much confused with the extremely different Nyctibora laevigata 

 (Beauvois). 



Of the North American roaches, this species shows some slight 

 superficial resemblance to Pycnoscelus siirinamensis; the different 

 form of the pale pronotal borders and numerous generic features 

 of difference, readily distinguish these widely separated forms. 



Characters of Male. — (Key West, Florida.) Size rather small for the subfamily. 

 Head with interocular space about two-thirds as wide as the interocellar space; 

 ocelli large and distinct; flattened surfaces of ocellar areas weakly oblique, but 

 with inner margins not raised above plane of flattened face. Maxillary palpi short, 

 fourth joint distinctly shorter than third or fifth and decidedly constricted proxi- 

 mad. Pronotum weakly convex, except laterad where it is strongly declivent; 

 cephalic margin very weakly .convex, transverse, rounding broadly into lateral 

 margins, which are weakly convex and strongly divergent caudad, rounding broadly 

 into the caudal margin, which is weakly con\-ex, trans\-erse. Tegmina and wings 

 (normally) slightly exceeding apex of abdomen (venation, pi. \'I, tig. 9). Supra-anal 

 plate delicate, produced but transverse, very weakly bilobate. Cerci very short, 

 compact, with (ten) distinct joints, these very brief, tapering to acute apex. Sin- 

 istral portion of anal chamber empt}', mesad a soft, sub-c}lindrical mantle projects 

 distad, with truncate distal margin supplied with a closely set fringe of microscopic 

 chitinous teeth. Dextral portion of anal chamber occupied by a large, convolute 

 chitinous plate. Subgcnital plate convex, asymmetrical; free margin very broadly 

 convex from sinistral base to mcsal portion of dextral half, there rounding sharply 

 into rather deeiily concave emargination at dextral base, within which the margin 

 is subchitinous. Minute, slender, cylindrical styles are situated on this margin at
