 PL XI, fig. 2.) 



c? ? . Head dark brownish grey, with rather long pale hairs ; 

 much flattened behind vertex, produced posteriorly ; irons simi- 

 larly coloured, about one-fourth the width of the head (at the 

 level of the vertex), widening a little below. Proboscis dark 

 brownish grey, with minute gold pubescence ; palpi blackish, 

 sparsely hairy. Antennal scape dark brown, sparsely haired, 

 2nd joint rounded, reddish yellow ; flagellum yellow, the joints 

 oval, becoming more elongated towards the tip, bearing a few 

 hairs each. Tliorax: neck long, dark grey, a blackish stripe on 

 the dorsum, and blackish where it joins the distinctly produced 

 prothorax. Dorsum of thorax light grey, mainly occupied by 

 three contiguous black stripes, of the usual pattern ; the outer 

 ones abbreviated in front, with a faint trace of a greyish line- 

 dividing them from the median one ; blackish behind the suture, 

 the post-sutural depression rather widely grey. Scutellum and 

 metanotum dark brownish grey, with whitish grey reflections 

 seen from behind ; sides of thorax dark grev, with lighter parts 

 here and there. Abdomen blackish or dark brownish grey, with 

 Very short pale yellow pubescence. Belly similar. Genitalia of 

 male reddish brown with yellow hairs ; an upper plate with a 

 pointed bright reddish brown piece projecting from underneath ; 

 a pair of large claspers, each joint large and fleshy, the second one 

 ending in a small claw ; a ventral plate with reddish yellow hairs 

 on the posterior margin. Apparently there is a pair of smaller 

 intermediate organs. Ovipositor of female large, somewhat com- 

 plicated ; the upper valve bright brownish yellow, the lower one 

 dark brown at the base, yellow at the tip. Legs : coxae blackish ; 

 remainder of legs yellow ; femora with a distinct black ring at tip,

 half of metatarsus. Wings pale grey, with a fairly well-defined 

 pattern of brown marks on the anterior portion and pale grey 

 ones on the posterior. Auxiliary vein ending opposite the 2nd 

 longitudinal vein, which begins beyond the middle of the wing ; 

 marginal cross-vein distinctly beyond middle of marginal cell, and 

 at tip of 1st longitudinal ; praefurca nearly half the length of 2nd 

 vein ; basal section of 3rd vein very oblique, double the length of 

 the anterior cross-vein, which is half as long as the basal side of 

 the discal cell ; discal cell twice as long as broad, much wider 

 distally, longer than 2nd posterior cell, equal (posteriorly) to 

 3rd posterior cell ; posterior cross-vein some little distance 

 anterior to discal cell; the 7th vein rather sinuous, tip bent 

 down rather sharply. The markings consist of a brown spot 

 on the costa near the base, with a minute clear spot in the 

 middle. Two nearly contiguous, sub-triangular spots follow, on 

 the costa, extending into the 1st basal cell, each spot with a small 

 clear space in it, this clear space placed on the costal margin. A
