ACULEATA. 

 DlODONTUS RETICULATUS, Sp. 110V. 



Niger, mandibulis late flavis ; geniculis, tibiis tarsisque anticis 

 flavis ; alis liyalinis, nervis stigmateque nigris. ? . Long, fere 

 5 mm. 



Hab. 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 mesopleura? without stout striations ; 

 the hinder tibia? and tarsi testaceous . . striolatus, Cam. 



Clypeus not roundly and deeply incised in the middle ; 

 the base of the mesopleura? with some stout stria- 

 tions ; the hinder tibiae only testaceous at the base reticulata. 



Antennas black ; the flagellum 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 propleura? with stout striations ; there are 

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

 one behind these, almost in the middle ; inesopleura? 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 metapleura? is smooth and shining ; the rest bears oblique 

 distinctly separated stria?. 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 tibia? and the anterior tarsi are for the 

 greater part testaceous ; the base of the hinder tibia? white ; there are 

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

 shorter spines on the apex on the outer side ; the middle tibia? 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 antenna? 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).
