(Stal), from which it differs in the somewhat larger size and in 



striking features of coloration. 60 



Type: d 1 ; Labuan, British North Borneo. [Hebard Collection, 



Type no. 815.] 



Size small, form slender, structure very delicate. Head smooth, 

 vertex acute, produced very slightly beyond margins of antenna! 

 scrobes, dorsal surface concave. Antennal scrobes produced 

 ventrad in a bluntly conical projection. Pronotum with minute, 

 scattered tubercles on disk and dorsal portions of lateral lobes; 

 disk flattened, defined from the lateral lobes faintly by contour 

 but strongly by coloration, with a subobsolete medio-longitudinal 

 sulcus and two decided transverse sulci, caudal margin broadly 

 convex; lateral lobes with cephalic and ventral margins straight and 

 tuberculate and forming an obtuse-angulation. Tegmina and 

 wings fully developed and capable of sustained flight. Tegmina 

 with costal margin broadly convex, sutural margin weakly convex 

 in stridulating field, thence nearly straight to distal extremity, 

 where it curves into the broadly rounded apex; scapular field broken 

 into irregular areolae; anal field very small; discoidal and median 

 veins gradually diverging in distal two-fifths, median vein branching 

 at end of proximal two-thirds, the branch forming an acute angle 

 and curving proximad so that it thence runs parallel to the ulnar 

 vein. Cephalic coxal spine lamellate, with ventral margin convex, 

 so that it is half as wide as long. Mesosternum narrower than 

 metasternum, cephalic and lateral margins weakly concave, these 

 margins produced, convex latero-cephalic angles minutely tuber- 

 culate, the cephalic margin subtuberculate to near median portion. 

 Ultimate tergite surrounded by preceding segment so that its 

 dorsal portion is alone visible, with caudal margin concave. Supra- 

 anal plate ovate, with greatest breadth distad and apical portion 

 moderately truncate. Cerci small, stout conical, straight, tapering 

 to apical portion which is folded inward at a right -angle to the 

 shaft and terminates in a minute spine which does not extend inward 

 so far as the inner margin of the shaft. Subgenital plate with 

 lateral margins concave, narrowing to distal portion, then widening 

 slightly to the truncate apex. Styles conical in proximal half, 

 filiform in distal half. Dorsal femoral margins moderately lamel- 

 late and smooth. Ventro-external femoral margins and dorso- 

 internal margin of caudal tibiae lamellate and armed with minute, 

 procumbent spinulae, except distad on caudal femora where (7 

 and 8) small, erect spines occur. The count for these limbs as 

 follows. Cephalic internal 14 and 14, cephalic external 15 and 15, 

 median internal 8 and 8, median external 17 and 20, caudal internal 

 2 and 3 (subobsolete), caudal external 28 and 31. Genicular lobes 

 of femora bluntly rounded. Mesosternum narrower than meta- 



60 As well as in the male genitalia, if these have been correctly described for 

 integer by Brunner.
