Genus monotypic. Genotype — Cycloptilum squamosum Scudder. 



Generic Description. — Form depressed, compact; surface clothed 

 with scales; pronotum produced caudad in male; tegmina absent 

 in female, projecting beyond pronotum in male. 



Head small, rounded, produced cephalad; interantennal pro- 

 tuberance with trace of vertical division. Pronotum of male narrow 

 cephalad, broadened and produced caudad, in length equal to about 

 half of the entire length of the body; of female subquadrate. Teg- 

 mina of male extending caudad of caudal margin of pronotum a 

 distance subequal to one-third the greatest pronotal length, tym- 

 panum perfectly developed, caudal margin of dorsal field of tegmina 

 strongly arcuate; lateral field of tegmina well developed. Ovi- 

 positor nearly straight, sub-lanceolate at apex, the latter with margins 

 unarmed. Subgenital plate of female with distal margin complete 

 or distinctly but transversely emarginate mesad. Cerci of both 

 sexes elongate, tapering. Cephalic tibiae with the cephalic face 

 bearing a distinct tympanum. Caudal femora greatly dilated; 

 caudal tibiae with three pair of well-developed distal spurs, the 

 dor so-internal shorter than the ventro-internal spur; caudal meta- 

 tarsus sulcate dorsad, serrate on both dorsal margins, the distal 

 extremity armed on both sides with a spur which extends well 

 beyond the base of the distal tarsal joint. 



Distribution in North America. — Extending from central New 

 Jersey southward to extreme southern Florida, westward in the 

 South through Texas to southern Arizona and theMojave Desert in 



35 The specimens from this locality recorded as Cycloptilus americanus by 

 Morse, Psyche, XII, p. 21, 1905, cannot be found. The present specimens 

 from the collection of Professor Morse were determined by him as that same 

 species, but the records have not been published. We feel, therefore, confident 

 that those specimens recorded as Cycloptilus americanus are the authors' new 

 species, Cryptoptilum trigonipalpum, to which the present specimens unques- 

 tionably belong.
