joint very small, less than one-fifth the length of the first third and 

 ourth joints of eqnal length which is about one-third that of basal 

 ioin b yond the fourth joint the segments are subcyhndncal gradually 

 le'^ing in length, the total number being twelve. Pr— 

 subequal anterior margin truncate, lateral margins subparaUel, 

 poSo broadly rounded; fine of depression crossing the median fine 

 posterior to the middle; median line shallowly sulcate m the anterior 

 haU ithtly carinate in the posterior half. Tegmma broad, shoulder 

 prLne'nt, narrowly rounded; lateral margins subparalle , apical po - 

 Z very slightly arcuate. Exposed portion o wings - her dongat 

 over halt as long as the tegmina, apex narrowly rounded Abdomen 

 up rin.-; basal segments with the lateral folds well <kv-eloped Anal 

 se'm^ transverse, posterior margin truncate. Subgenita plate 

 ^"th the post^ro-lateral angles each produced into a recurved spim- 

 tom process, which flank the lateral base of the forceps; postenor 

 margin roundly emarginate. Forceps parallel, simple, ^^^>^;^^^' 

 internal borders strongly crenulo-dentate ; surface supplied with long 

 h"remora and m. of subequal length, the anterior femora 

 considerably heavier than the median and posterior pair. Tars, with 

 the third ioint heart-shaped, flattened. 



% neral' color wood-brown; the median portion o the pronotiun 

 the marc-ins of the tegmina and exposed portions of the wings, the 

 aMomen forceps and antennal markings of a darker tint than the 

 r"aMe'r of the body which is of a sienna tone. Antenna with the 

 CTeld, tenth, eleventh and twelfth dark, the eighth partially so, 

 S; the ninth has the basal portion dark, the remainder being 



""ttedium, larger than the male; form rather robust. Abdo- 

 men expanded the greatest width being median. Anal segment 

 ILtr S bgenitll plate produced subtriangular. Forceps prac- 

 tLX tte same fn structure as those of the male, but more elongate 



"Ceratcolor as in the male. Antennae with the basal and apical 

 portions of the first, the second, seventh and eighth joints dark.
