given in the generic diagnosis, we would note that the present species 

 "appears to differ from all others, assigned to the group Nanomantes 

 by Giglio-Tos, in the simple immaculate coloration of limbs and 

 organs of flight. 



Type. — cf; Singapore, British Straits Settlements, Malay Penin- 

 sula. (From C. F. Baker.) [Hebard Collection Type No. 519.] 



In addition to the characters described in the generic treatment, 

 we would give the following. Facial scutellum five times as broad 

 as high; dorsal margin weakly defined, transverse mesad, oblique 

 laterad. Antennae and costal margins of tegmina microscopically 

 ciliate. Short, straight, oblique or vertical veinlets connect the 

 marginal and mediastine and mediastine and humeral veins of 

 the tegmina and wings. Cephalic femur with ventral surface 

 supplied with hairs and within the external spines somewhat angu- 

 lately ridged and denticulate; ventro-internal margin with spines 

 extending to opposite distal margin of femoral brush, alternating 

 long and short, except the three successive smaller spines beneath 

 femoral brush, the elongate terminal spine longer than any of the 

 others. Supra-anal plate triangular, with apex rather broadly 

 rounded. Subgenital plate with lateral portions narrowly curved 

 upward; dextral portion evenly and weakly convex, sinistral por- 

 tion straight in proximal half, then in remaining portion similarly 

 convex and convergent with dextral portion; at the apices of these 

 margins are situated minute styles, about three times as long as 

 broad, separated by a brief interval, in which median portion the 

 plate is very thin with margin angulate emarginate at slightly less 

 than ninety degrees. 



Body and limbs immaculate, pale yellowish brown, probably 

 pale green in life, as is indicated by the presence of a few minute 

 irregular green patches. Eyes blackish chestnut brown. Tegmina 

 and wings hyaline, iridescent, almost clear, showing an exceedingly 

 faint tinge of yellowish brown. Humeral vein and both median 

 and discoidal veins, as far as the colorless stigma, purplish vina- 

 ceous. 



Length of body 18.5, length of pronotum 5, length of pro- 

 notal collar 1.8, greatest width of pronotum 1.7, length of teg- 

 men 14.7, width of tegminal marginal field .8, length of wing 

 13.7, length of cephalic femur 5.3, length of caudal metatarsus 

 4 mm.
