united ; the basal abscissa half the length of the second, not quite 

 so long as the first transverse cubital nervure ; recurrent nervure 

 received close to the apex of the first cubital cellule. Antennal 

 scape short, ovate ; the second joint is longer than the third. There 

 are more or less distinct longitudinal furrows on the centre of the 

 abdominal segments. Hind coxae long. Post-scutellum stoutly 

 keeled down the middle on the basal half, the keel touching the apex 

 of the scutellum. Stigma lanceolate. Transverse median nervure 

 received beyond the transverse basal. Malar space longish. 



Characteristic of this genus are the punctured metanotum, fur- 

 rowed down the middle, closely striated abdomen, with the segments 

 deeply separated and furrowed down the middle, and short, broad, 

 sessile first segment. The two species known to me may be sepa- 

 rated as follows : — 



Reddi&h, with black head ; wirf^s fuscous, with two hyaline 



clouds near the stigma ni(iriccp-<. 



Yellowish luteous, wings fuscous, yellow at the base, the head 



yellow, with a large black mark nuiciilircpK. 



Telerda nigriceps, sp. nov. 



Eeddish-ferruginous ; the head, except a line above and below on 

 the inner orbits, the clypeus, a line, longer than it and narrowed 

 above, projecting from it, this part being keeled, the malar space and 

 apex of mandibles, black ; the face sparsely haired, the front finely 

 aciculated. Basal joints of palpi black, the apical testaceous. 

 Lower part of pro thorax at the base, a large oval mark on the middle 

 of mesopleurae and tegulae, black. The metanotum covered with 

 fuscous hair; it is sparsely, but sti'ongly punctured; the furrow 

 widens out gradually towards the apex. Abdomen closely, regularly 

 longitudinally striated, the striae interlacing, forming almost reticu- 

 lations on the sixth segment ; the penultimate is more strongly, 

 sharply striated ; the last is smooth, with black cerci. The basal 

 half of the costal and submedian cellules smoky, the apical fuscous- 

 yellowish ; the first cubital cellule broadly in the middle and a 

 cloud outside the recurrent nervure hyaline ; the stigma red, black 

 at the apex. $ . 



Length 12 mm. ; terebra 2 mm. 



■■'• Telerda maculiceps, sp. nov. 



Luteous, the antennae, a large mark on the front and vertex pro- 

 longed as a small triangle on to the top of the occiput, black ; the 

 base of the second abdominal segment, the greater part of the third
