REHN AND HEBARD 139 



sinuato-truncate; supra-anal plate slightly transverse, in general form 

 similar to the type found in the majority of the species of the genus; cerci 

 similar in general form to those of other species, sharply bent inwards at 

 distal fourth, the angle hardly rectangulate, the apex acute, depressed; 

 subgenital plate narrowing distad, in general rather broad, distal margin 

 broad, subtruncate, lateral styliform processes short, tapering, ventral sur- 

 face with prominent rounded lateral carinae and a less decided subangulate 

 median one, the latter not quite reaching the distal margin, the lateral ones 

 continuous with the styliform processes. Limbs not greatly elongate, 

 dorso-genicular region of cephalic and median femora subcompressed but 

 not acute produced, genicular lobes of same femora bispinose, of caudal 

 femora unispinose; cephalic femora slightly less than three times as long as 

 the pronotum, cephalic tibiae with elongate elliptical foramina; median 

 femora subequal to the body in length; caudal femora slightly longer than 

 the tegmina, moderately inflated proximad, caudal tibiae surpassing the 

 femora by more than the pronotal length. 



Allotype. — 9 ; Same data as the type. 



Description of Allotype. — The following characters are those of difference 

 from the description of the type. Fastigium smaller, less elevated and 

 more compressed than in the male, sulcus equally impressed; face more 

 flattened cephalad than in the male and with indications of infra-antennal 

 ridges; eyes very slightly more longitudinal than in the male. Pronotum 

 with the greatest transverse width across the ventral portions of the lateral 

 lobes slightly greater than the dorsal length of the pronotal disk, the latter 

 less elevated caudad than in the male and with the greatest caudal width 

 less than two-thirds of the length, caudal margin of disk subrectangulate 

 with the immediate angle not rounded; lateral lobes appreciably longer than 

 deep, surface of the metazonal section of the lobes less buUate than in the 

 male. Tegmina a fourth again as long as the body (exclusive of the oviposi- 

 tor) ; lobate marginal field slightly more than a fourth of the length of the 

 entire tegmen; anterior ulnar vein reaching the sutural margin distinctly 

 distad of the middle and with its rami much less apparent than in the male. 

 Proximo-dorsal abdominal segment without erect process; disto-dorsal 

 abdominal segment deplanate dorso-mesad, the flattened area angularly 

 margined laterad, distal margin of segment subarcuate, flattened mesad; 

 supra-anal plate much as in male; cerci terete, moderately elongate; ovi- 

 positor slightly surpassing the femora in length, moderately deep, regularly 

 arcuate, distal half of dorsal margin serrato-dentate, greater part of ventral 

 margin crenulate becoming serrato-dentate distad, the serrations all re- 

 curved and smaller than those on the dorsal margin, distal extremity of the 

 valves rounded in outline, surface of distal half of valves scabroso-dentate, 

 the denticles in general arranged as in the other species of the genus, but 

 the series are less regularly defined; subgenital plate trigonal, bicarinate 

 mesad. INIedian femora about three-fourths the length of the body. Cau- 

 dal femora about a third again as long as the tegmina.
