minute teeth anteriorly ; eyes with their inner orbits parallel, cheeks 

 strongly developed, as broad as the eyes or nearly so ; anterior ocellus 

 closer to the posterior ones than the latter are to one another ; median 

 segment laterally with a small tubercle. Black ; the mandibles and 

 the tibia? and tarsi yellow, the tibiae darker in the centre ; wings 

 hyaline, nervures and tegula? testaceous. 



$ Similar ; olypeus and front with silvery pubescence, flagellum 

 of antenna? pale below, eyes divergent towards vertex. 



Long. 4-5 mm. 



Habitat : Deesa ; Quetta ; Peshin ; six specimens. 



This species is nearest to D. geniculates, but may be separated from 

 it by the lateral tubercles on the median segment. 



DlODONTUS RUSTICUS 11. sp. 



$ Head rather closely and coarsely punctured, the punctures on 

 the front running into stria*, thorax sparsely punctured, median 

 segment reticulate abdomen microscopically witb minute and not 

 very close punctures ; clypeus with the anterior margin rounded, 

 labrum notched ; eyes divergent towards the vertex, cheeks well 

 developed ; antenna? long, filiform, the apical joint the longest. 

 Black ; the tibia? and tarsi more or less pale testaceous, the latter 

 darker in the middle ; front with thick silvery pubescence ; wings 

 hyaline, nervures black, tegula? pale testaceous. 



Long. 5 mm. 



Habitat : Quetta ; Peshin ; six specimens. 



The only Indian species hitherto described which has black man- 

 dibles.

9 Impunctate, or nearly so, except the scutellum and median 

 segment, which are somewhat sparsely and shallowly punctured ; eyes 

 convergent below, their width apart at vertex being about twice that 

 at base of antenna 1 , their facetting fine and regular ; ocelli very 

 small, the distance apart of the posterior ones being greater than their 

 distance from the margin of eyes ; clypeus broader than long, its 

 anterior margin produced and almost transverse; antenna? long, filiform^ 

 inserted not much above the posterior margin of clypeus, the second joint 

 of flagellum the longest, third and following joints gradually decreasing 

 in length to apex; cheeks well developed, their width being more 

 than half the width of the eyes; pronotam narrow, mesosteinum
