tegmina the appearance of "oblique truncation" originally de- 

 scribed. The enormous stridulating field of the male is 26.4 milli- 

 meters in length, 18.3 in width, the stridulating vein 14.7 milli- 

 meters long. The large, transparent, rounded speculum of the 

 dextral tegmen, bounded by a very high and heavily chitinous wall 

 caudad, probably aids greatly in producing what should be one of 

 the very loudest of insect stridulations. 



The extreme basal slenderness of the caudal femora (these limbs 

 are present only in the male before us), armed with rather decided 

 spines ventrad, is a striking feature. Greatest width proximad 

 3.9, median width 3, distal width 3.7 millimeters. The greater 

 distal width is caused by a pronounced medio-longitudinal, dorsal 

 carina being there developed. The vental femoral margins are 

 armed with spines as follows. Cephalic internal cf 4 and 4, 

 9 10; cephalic external 0; median internal 0; median external cf 5 

 and 7, 9 11 and 12; caudal internal cf. 11 and 12; caudal external 

 cf 14 and 14. 



The female before us appears to represent the same species as 

 the male, the differences shown being attributable to sexual di- 

 versity. This can, however, not be proven conclusively without 

 comparison of additional material, though van Vollenhoven was 

 satisfied as to the specific agreement of Bornean and Javanese ma- 

 terial. 



The egg in this species is 16.2 millimeters in length, 3.1 milli- 

 meters in greatest width. 



Length of body cf 55, 9 67; length of pronotum cf 17, 9 18; 

 cephalic width of pronotum cf 7.7, 9 8.4; greatest (meso-caudal) 

 width of pronotum cf 17.3, 9 15.9; length of tegmen cf 96, 9 130; 

 greatest width of tegmen cf 32, 9 38.9; length of cephalic femur 

 cf 27.3, 9 36.8; length of caudal femur cf 56.7, 9 — ; length of 

 ovipositor 34.3; greatest width of ovipositor beyond immediate 

 base 6 mm.
