segment is longer than the prothorax in temiescens, and the sub- 

 genital plate has the caudal margin less produced and more sub- 

 truncate than in that species. 



Type: cf ; Homestead, Dade County, Fla. July 10-12, 1912. 

 (Rehn and Hebard.) [Hebard Collection.] 



Size, form, general structure and proportions, and coloration as 

 in tenuescens, differing in the following characters: Abdomen with 

 the first to sixth segments slightly more 

 longitudinal, the apex of the caudal femora 

 not quite reaching the distal margin of the 

 fourth segment; seventh, eighth and ninth 

 dorsal segments together no longer than the 

 sixth segment; seventh segment longitu- 

 dinal, lateral margins subparallel, not ex- 

 panding caudad; eighth segment slightly 

 transverse, but slightly more than half the 

 length of the seventh segment, not com- 

 pressed; ninth dorsal segment shorter than 

 the seventh segment, the greatest width 

 (caudal) but slightly greater than the 

 length, fornicate, lateral margins converging 

 proximad, distal margin arcuato-emarginate, 

 exposing the strongly arcuate extremity of 

 the supra-anal plate; cerci of the bent- 

 arcuate type found in tenuescens, but with 

 the proximo-internal base with a very blunt, 

 subincrassate obliquely directed tooth; subgenital opercule small, 

 shallower, and less pendulate than in tenuescens. 



Allotype: 9 ; Miami, Dade County, Florida. March 28, 1910. 

 (Hebard.) [Hebard Collection.] 



Size, form, general structure and proportions, and coloration as in 

 tenuescens, differing in the following characters: abdomen with the 

 sixth dorsal segment considerably longer than the seventh and 

 eighth dorsal segments; ninth dorsal segment equal in length to 

 prothorax; subgenital plate with caudal margin very little produced, 

 rotundato-subtruncate.
