166 GENUS CARIBLATTA (oRTHOPTERa) 



constant in typical lutea in having the distal margin between the 

 specialized styles rather broadly and weakly produced, the 

 produced portion forming a strongly transverse rectangle. 



The following features are found in a joair from Spring Creek, 

 Georgia, cf . Size small, form slender. Pronotum with point 

 of greatest width distinctly caudad of the normal meso-caudal 

 point in the species of the genus; caudal margin truncate, very 

 weakh' convex.^^ Tegmina moderately reduced, not quite reach- 

 ing apex of abdomen, with four longitudinal discoidal sectors, 

 the cross-veinlets very weakly defined.-* Wings of equal length, 

 reduced, the ulnar vein simple or forked, the intercalated 

 triangle minute.^^ Supra-anal plate very small, strongly trans- 

 verse, very weakly produced with distal margin very broadly 

 convex and emargination weakly indicated mesad. Subgenital 

 plate moderately produced, with lateral margins distinctly raised; 

 styles weakly inset, these specialized as in p^inctulata; space 

 between styles about one fourth of the free margin, this median 

 portion symmetrically produced, truncate, the production trans- 

 verse rectangulate and nearly three times as broad as long.^*' 



9 . Agrees with the male except in the following features. 

 Form distinctly less slender. Tegmina and wings rather decidedly 

 reduced and showing the resultant coincident reduction in the 



-^ As we have found elsewhere in the Blattidae, tegminal reduction appears to 

 be accompanied by a broadening of the pronotum, with a lessening of the con- 

 vexity of the caudal margin and a coincident shifting caudad of the point of 

 greatest pronotal width. The pronotal features given above show rather this 

 adjustment than what might appear to the casual observer to be features sepa- 

 rating the present species widely from the other members of the genus. 



2^ These features are exactly as would be expected in such cases of tegminal 

 reduction; where moderate reduction is found in the present species five to 

 four discoidal sectors are present, where moderately decided to decided reduc- 

 tion occurs five to three, four being usual in females of the typical race, three 

 being frequently found in both sexes of lutea minima. 



■6 These features are exactly as would be expected in such cas(>s of wing 

 reduction. 



-^ The Lakeland specimens show a tendency toward lutea minima; the male 

 has this production only twice as broad as long.
