plate, it then shows a roundly elevated U-shaped ridge, above which 

 the surface is raised in a rounded Y-shaped ridge, the apices rounded 

 and projecting, while dorsad between these the surface is deeply 

 concave, with dorsal margin bilobate beneath the bifid apex of the 

 ultimate tergite. Subgenital plate medio-longitudinally subsul- 

 cate, lateral margins broadly convex to very slender apices, between 

 which the distal margin is U-emarginate, these lateral apices Sur- 

 mounted by slender tapering styles, each about three times as 

 long as its basal width. Limbs and their armament much as in 

 cryptosticta, except that the genicular lobes of all the femora are 

 bluntly rounded. Longest spine of cephalic tibiae slightly over 

 twice the tibial width at that point. 



Allotype: 9 ; Dapitan, Mindanao, Philippine Islands. (From 

 C. F. Baker.) [Hebard Collection.] 



Agrees closely with male, differing as follows. Production of 

 pronotum caudad decidedly shorter, the metazona three-quarters 

 as long as the prozona. Supra-anal plate and cerci much as in 

 cryptosticta. Ovipositor more elongate than in that species, the 

 apex of the ventral valves much as in dicera. Subgenital plate 

 medio-longitudinally subcarinate, distal third broadly angulate 

 emarginate with margins of this emargination feebly concave, 91 

 the lateral angles thus formed nearly as long as their basal width, 

 their apices sharply rounded and forming an angle of slightly less 

 than ninety degrees. 



General coloration light yellowish brown, green distad on organs 

 of flight and caudal limbs; in life light green. Genicular lobes of 

 cephalic and caudal femora suffused distad with dark brown, this 

 narrowly margining the dorso-distal extremity of these members 

 as well, though there very weak on the cephalic femora. Antennae 

 and tegmina marked as in cryptostosticta. The males have a dark 

 brown suffusion on each tegmen at the caudal extremity of the 

 stridulating area. 



The measurements of the type are given first for the males, 

 those of the allotype first for the females. Length of body d 71 15 

 and 14, 9 17.2 and 14 (shrivelled); length of pronotum d 71 4.8 

 and 5.2, 9 4.7 and 4.6; greatest width of pronotum cf 2.7 and 2.7, 

 9 2.8 and 2.8; length of pronotal lateral lobe c? 2.7 and 2.8, 9 3 

 and 3; depth of pronotal lateral lobe c? 2 and 2, 9 2.1 and 2.1; 

 length of tegmen d" 20 and 20.8, 9 23.9 and 22.3; width of tegmen 

 cf 2.7 and 2.8, 9 3.1 and 3 ; length of cephalic femur c? 5.7 and 5.7, 

 9 6 and 5.9; length of caudal femur tf 12.8 and 13.3, 9 14.7 and 

 14.7; length of ovipositor 12 and 12 mm. 



In addition to the described pair, a paratypic male bearing the 



91 The female from the Island of Basilan has this emargination decidedly more 

 nsivc, occupying the distal two-thirds of the subgenital plate. In all other 

 features it agrees so very closely with the allotype that we believe this difference 

 to be attributable to individual variation.
