of the scutellum white, the frons is coloured differently and the 

 male pygophor different. T am indebted to my friend Mr. Van 

 Duzee for a pair of his pucUa. * 



19. astyanax sp. nov. 



PI. X. fig-. 20: PI. XIV, figs. 13-15. ** 



Closely allied to D. pitclla, but smaller, the genae and scutel- 

 lum entirely black, and the lateral margins of the frons more 

 rounded laterally. Tn tlie short-winged form, the tegmina are 

 subtruncate, and broadly margined with wdiite apically. Spur 

 with about 14 spines. 



Male pygophor exceedingly remarkable. The anal tube is 

 elevated and shaped somewhat like a square hood. The lateral 

 margins of the pygophor close to the anal tube project acutel\' 

 and somewdiat curvedly. Genital styles truncate apically, the 

 angles being acute and j^roniinent. The oedeagus has a crown of 

 4 long spines (or is apically elongately quadrifid in other words). 



Length about 1% (brach.), 2V1 (macr.) mill.

20. ali^cbra sp. nov. 



PI. X, figs. 16-17; ri. X\'. figs. 15-16. 



Closely allied to D. piiclla liut (in the short-winged forms at 

 least) the tegmina are deeply fuscous and more opaque; basal 

 half of commissure and a tiny spot near the apex internally 

 whitish. The median keel of the frons is rather thick and whit- 

 ish, and the lateral keels of the pronotum are straight and reach 

 the hind margin. Spur with 33 spines. 



Male pygophor suboval. broadly produced near the anal tube, 

 which has 2 projections from the ventral wall. The genital .styles 

 are widened and truncate apically. the outer angles rounded, the 

 inner acutely produced. 



Length i7/g mill (brachypterous form only known).

^r. Melichar kindly sent me some years ago a male of the Sinhalese a7hi^?o^^^ 

 Motschoulskv. the male pvgophor of which is figured PI. U Ag^; l*'-!^; It js subro in 

 date viewed end on and has a flat projection on each side near the anal tube turmng 

 a little outwards and very conspicuous in Proflle. The analtube has no spino-e pro 

 jections. The oedeagus is apparenUy short. Genital styles less arched than in pneUa 

 and dilated apically, being shorUy bifid, the angles acute. ,.„„.„^ ^:hr.nirl V>p more 



-^ PI. 10 f. 20 is hot quite accurate, the lateral margins of the vertex should be more 



concave.
