for about two-thirds of the scutal length, and often perceptible to the 

 posterior margin, at first converging, then diverging gradually ; emargina- 

 tion slight, scapular angles short but fairly sharp ; punctations numerous, 

 discrete, fairly deep, of moderate size. Venter : vulva between coxae IV ; 

 genital grooves nearly straight, slightly diverging; anus very posterior; 

 anal groove short, horseshoe-shaped ; spiracle fairly large, transverse- 

 oval. Capitulum (Fig. 219): base sub-triangular, much broader than long, 

 with slightly concave posterior border and with sides parallel for a short 

 distance ; cornua absent ; porose areas elongate-pear-shaped, the broader 

 ends internal, the interval fairly broad ; fairly distinct auricular ridges 

 ventrally. Palps long, the external contour noticeably concave, article 2 

 half as long again as article 3 which terminates bluntly. Hypostome as 

 long as the palps, 2 j 2, but a short additional internal row of teeth (3 per 

 file) on either side in the anterior portion ; median unarmed area fairly 

 large, especially posteriorly. Legs fairly strong, coxae rather elongate, 

 coxa I with very slight internal spur, coxae II-IV without spurs, but 

 with trenchant posterior borders, especially coxae II and III ; tarsi 

 tapering gradually, the terminal much longer than the basal segment.
