By p. Cameron. 



ACULEATA. 

 DiODONTUS RETICULATUS, Sp. HOV. 



Niger, mandibulis late flavis ; geniculis, tibiis tarsisque anticis 

 flavis ; alls hyalinis, nervis stigmateque nigris. ? . Long, fere 

 5 mm. 



Hah. Deesa (Major C. G. Nurse). 



This species comes near to D. striolatus, Cam., from Lahore. 

 The two may be separated thus : — 



Clypeus roundly and deeply incised in the middle ; the 

 base of the mesopleura3 without stout striations ; 

 the hinder tibite and tarsi testaceous . . striolatus, Cam. 



Clypeus not roundly and deeply incised in the middle ; 

 the base of the mesopleurse with some stout stria- 

 tions ; the hinder tibise only testaceous at the base reticulatus. 



Antennae black ; the flagellam with a pale microscopic pile. Head 

 black ; the front and vertex minutely and sparsely punctured ; the face 

 is thickly covered with silvery pubescence ; the apex of the clypeus 

 almost transverse. Mandibles yellow, their apical third black. Thorax 

 shining ; the base of the propleurae with stout striations ; there are 

 two stout long oblique slris behind the middle, and a shorter curved 

 one behind these, almost in the middle ; mesopleurs with stout, widely 

 separated keels on the basal half, which form irregular reticulations ; 

 the basal half coarsely aciculated, the apical smooth and shining. The 

 base of the metapleur^ is smooth and shining ; the rest bears oblique 

 distinctly separated striae. The base of the median segment bears 

 stout oblique keels, which run into irregular reticulations in the middle ; 

 the apical slope is irregularly transversely striated ; the fovea is large 

 and deep. The four anterior tibiae and the anterior tarsi are for the 

 greater part testaceous ; the base of the hinder tibiae white ; there are 

 four longish spines on the hinder tibiae, and there are three or four 

 shorter spines on the apex on the outer side ; the middle tibiae are 

 similarly but not so strongly spined. Abdomen smooth and shining ; 

 the apical half covered with a pale down. 



Cerceris simlaensis, sp. nov. 

 Black, largely marked with yellow, and thickly covered with white 

 hair ; the scape of the antennae beneath yellow ; the third joint and 

 the base of the fourth rufous ; legs yellow ; the four anterior femora 

 largely marked with black behind ; the hinder pair with the apical 

 two-thirds black ; the basal area on the median segment stoutly longi- 

 tudinally striated. ^ . Length, 10-11 mm. 



Hab. Simla (Nurse).
