fulvous, with paler hair. Wings hyaline, slightly tinged 

 with fulvous ; the nervures and stigma black. ? . 



Length 14 mm. 



Hub. Khasia Hills. Coll. Rothney. 



Clypeus punctured ; in its centre a stout keel which 

 reaches near to the apex ; the face tuberculate in the middle, 

 its apex and that of the lahrum margined ; on the centre of 

 the face at the apex is a broadly triangular yellow-fulvous 

 mark; on either side of the top of the labrum is a brownish 

 mark, with two projections, the inner of which is raised. 

 There is a dark brownish plate on the outer side of the base 

 of the hind tibiae, which is longer than broad, shield-shaped, 

 roundly narrowed towards the apex, and with the outer edges 

 raised. Basal four abdominal segments fringed with pale 

 fulvous hair, the apical with longer black hair all over ; the 

 pygidium bare, with the sides broadly depressed on the apical 

 half. Vertex smooth and shining, the front punctured, with 

 a narrow keel down the centre. 



What I suppose is the male has the head black, except the 

 clypeus, which is pale yellowish testaceous ; the lower part of 

 the front and the sides of the clypeus thickly covered with 

 depressed fulvous pubescence, as is also the greater part of 

 the thorax ; the abdomen above is black except the base and 

 apices of the basal two segments broadly, and the ventral 

 surface, which are honey- coloured ; the legs are similarly 

 coloured, except that the coxse, trochanters, femora, and hind 

 tibia? are black above ; the hind femora become gradually 

 roundly dilated from the base to the apex ; the hind tibiae 

 curved, not swollen. Clypeus margined laterally, not very 

 convex, its apex transverse, margined narrowly on the inner 

 edge. Antennas entirely black. The wings are more clear 

 hyaline than in the female, and the nervures and stigma are 

 lighter coloured. 



Compared with Bingham's figure of H. Magrettii the male 

 of the present species has the thorax only very slightly haired 

 and the hind femora are not at all so strongly dilated ; its 

 abdomen, too, is longer and narrower. It (the male) appears 

 to be much more slenderly built than any species of Habro- 

 jjoda I have seen, is much les-s hairy, and has a much longer 

 malar space, the eyes being widely distant from the base of 

 the mandibles. The third joint of the antennas is swollen, 

 not narrowed at the base, and is hardly so long as the 

 fourth, whereas in what I take to be the male of H. Radosz- 

 kowskii it is clearly longer and distinctly narrowed at the 

 base. In neither the female nor the male of my species is 

 the second recurrent nervure interstitial. The Indian species
