but not closely striated, and has a wide, moderately deep 

 furrow down the middle. Pro- and mesopleuras closely 

 rugosely punctured ; the basal half of the metapleurae is 

 covered sparsely with shallow round punctures ; the lower 

 half has them much more widely separated. Legs rufous ; 

 all the coxsj and trochanters, the hinder femora, and the 

 hinder tibiae except at the apex are black. Wings dark 

 fuscous-fulvous, iridescent; the stigma testaceous; the ner- 

 vures blackish ; the second cubital cellule is equal in length 

 to the space bounded by the first transverse cubital and the 

 second recurrent nervures. Abdomen dark ferruginous, the 

 base of the segments darker, the apex ot the first and second 

 with a broad dull yellowish band.

Hob. Khasia Hills. Coll. Rothney. 



Antennas rufous, the flagellum darker above ; the third 

 joint is slightly but distinctly longer than the following two 

 united. Head smooth, the front and vertex covered with a 

 silky down, the clypeus sparsely with black hairs and with a 

 few punctures ; above it is distinctly incised, roundly in the 

 middle ; the apex is triangularly produced, the middle point 

 rounded. Mandibles rufous, sparsely punctured in the middle ; 

 the three teeth are sharply pointed and of almost equal size. 

 Thorax smooth, the mesopleurge closely punctured, the punc- 

 tures deep and distinct ; metapleuras obscurely striated, the 

 base indistinctly crenulated. The mesosternum has the apex 

 and the middle at the base black, as are also the edges of 

 the divisions and the central furrow on the metanotum. 

 Legs coloured like the thorax, the hinder femora lined with 

 black on the outer half above ; the apical four joints of the 

 metatarsus yellow. Abdomen smooth and shining, silky : 

 the petiole is black at the base, it and the other segments are 

 narrowly lined at the apex with pale yellow. 



A distinct species. Characteristic is the form of the clypeus, 

 which is longer than usual compared to its breadth, it being 

 much longer than broad, and is more largely developed below 

 the eyes than usual.
