Hah. Khasia Hills (coll. Kothney). 



Antennae stout, slightly dilated and compressed before the middle ; 

 the tenth to fifteenth joints white below ; the scape minutely punc- 

 tured, thickly covered with white pubescence. Head black ; the face, 

 clypeus, labrum, except in the middle, the inner orbits, the outer on 

 the lower half — narrowly above, broadly below, the yellow extending to 

 the base of the mandibles — pale yellow. Face and clypeus punctured, 

 thickly covered with short white hair ; the front above closely 

 punctured. Thorax black ; the edge of the pronotum, two short 

 lines shortly behind the middle of the mesonotum, the scutellum, 

 post-scutellum, two somewhat triangular marks on the sides of the 

 metanotum, extending on to the spiracular area, the tubercles, a large 

 mark on the under side of the mesopleurfe — rounded in front, obliquely 

 narrowed at the apex — pale yellow. Mesonotum opaque, distinctly 

 punctured in the middle, less distinctly and more closely on the sides; 

 and thickly covered with short fuscous pubescence. Scutellum roundly 

 convex, punctured, and thickly covered with long pale hair ; post- 

 scutellum smooth, thickly covered with fuscous hair. Median segment 

 rugosely punctured ; the supramedian area has the basal half narrowed; 

 the base in the middle transverse and slightly more than half the 

 width of the apex ; inside it is not depressed, is smooth and shining ; 

 the apex with two rows of punctures, the basal row not reaching to 

 the sides ; the posterior median and posterior intermedian area? are 

 stoutly transversely striated, the latter more strongly than the former. 

 Pro- and mesopleur^e closely punctured, their apices more or less 

 striated ; metapleuras closely rugosely punctured, above the middle 

 keel more or less obliquely striated. The lower part of the stigma and 

 the apical nervures are fuscous; the areolet five-angled, at the top 

 half the width of the bottom ; the recurrent nervure is received shortly 

 behind the middle. Legs black ; all the trochanters, the four anterior 

 coxfe, the apices of the four anterior femora, the anterior tibiae in front 

 and at the base behind, the basal part of the intermediate to shortly 

 beyond the middle and the basal two-thirds of the hinder pair, and an 

 irregular mark on the top and sides of the hinder femora — broad 

 above, narrow on the sides — pale yellow ; tarsi pale yellow, the basal 

 three joints at the apex and the apical two entirely black. Abdomen 

 black ; the apex of the petiole yellow ; the second and third segments 

 entirely, and the base and sides of the third, ferruginous. The petiole 

 is depressed in the centre above, the base irregularly roughened ; the 

 apex rugosely punctured ; the base of the post-petiole rugosely punc- 

 tured; the apex less strongly punctured ; the sides are closely, strongly, 

 obliquely striated ; the second, third, and fourth segments are closely 

 punctured ; the second closely, longitudinally striated at the base ; 

 the gastroccBli on their inner sides with curved striae. 



AcANTHOJOPPA, gen. nov. 

 Antennae dilated and compressed beyond the middle. Scutellum 

 pyramidal, the base with an oblique slope ; the top roundly depressed ; 

 the sides of the top leaf-like ; the apex has a more abrupt slope, is
