 short (Text-fig. 200) ; ventral thecal appendages symmetrical (Text-fig. 293) ; 

 first gonocoxae small, with rounded lobe-like apices (Text-fig. 242) ; spermatheca 

 elongated and thin, with a long curved neck, giving a small knob near its apex 

 (Text-fig. 228)) ......... discoidalis (p. 87) 



4 Paraclypeae remarkably elongated, cylindrical and pointed (Text-fig. 322) ; lateral 



black line only faintly represented by two brownish black dots, one on sides of 

 antenniferous tubercles and the other on collar. (Ventral thecal appendages 

 symmetrical (Text-fig. 325) ; right lateral conjunctival appendages three in 

 number (Text-fig. 324) ; dorsal membranous appendage with a pointed hooked 

 terminal and a short curved dorsal appendage (Text-fig. 324) ; spermatheca with a 

 broad median flange and a tube which is twisted at the base (Text-fig. 229))

- Paraclypeae short, thick at base ; lateral black line represented on sides of antenni- 



ferous tubercles, extending back to the sides of collar. (Ventral thecal appendages 

 asymmetrical (Text-fig. 337) ; right lateral conjunctival appendages two in 

 number (Text-fig. 338) dorsal membranous appendage with a bulb-like terminal 

 and a bilobed dorsal appendage (Text-fig. 338) ; spermatheca short, flask-shaped 

 with a transverse neck (Text-fig. 238)) .... sakdapolrakae (p. 102) 



5 Posterior third of dorsum of abdomen black, apical segments of antennae pale both 



at bases and apices ; paraclypeae acutely pointed, claspers narrow at base, 

 strongly and abliquely truncate (Text-fig. 203). Ventral thecal appendages 

 spiny (Text-fig. 287) ; spermatheca short, twisted at apex (Text-fig. 231) costalis (p. 85) 



- Dorsum of abdomen uniformly pale, brown or ochraceous ; apical antennal seg- 



ments never pale at both bases and apices ; paraclypeae never acutely pointed 6 



6 Hemielytra, except costal margins above the membrane, dark black, claspers 



extending well beyond pygophore, with broad truncated apices (Text-fig. 273). 

 (Second right lateral conjunctival appendage bifurcated (Text-fig. 2i6,F) ; sperm- 

 atheca linear and thin (Text-fig. 230)) ..... biguttata (p. 80)

8 Paraclypeae long, somewhat pointed, smoothly regular (Text-fig. 296) ; claspers 



usually extending slightly beyond pygophore, apices pointed. (Second right 

 lateral conjunctival appendage short, thicker in middle and pointed at apex 

 (Text-fig. 220) ; spermatheca below flange elongated and pointed (Text-fig. 234))
