 OF THE BOMBAY PRESIDENCY. 



By 



P. Cameron. 



With 2 or 3 exceptions the species described in this paper have been taken 

 at Deesa and Matheran by Lieut.-Col. C. Gr. Nurse. 



SCOLIIDiE. 



Discolia nigrobimaculata, sp. nov. 



Red, yellow and black ; the antennae, face, clypeus, base of mandibles, a line, 

 behind and touching the hinder ocelli, uniting the eyes at the hinder edge 

 transverse in front, rounded behind, occiput, thorax, basal segment of abdomen 

 except at the apex, the 5th and following segments, the ventral, and the legs, 

 ferruginous, the front and vertex, except for the transverse line, the outer or- 

 bits, and the 2nd, 3rd and 4th abdominal segments for the greater part pale 

 orange yellow ; the following parts are black : the mandibles except at the 

 base, a narrow line of equal width on the apex of the 1st abdominal segment, a 

 wider one on the 2nd, obliquely dilated in the middle, a narrower one, less strongly 

 dilated in the middle, on the 3rd, similar lines on the base of the 2nd to 4th 

 segments, but more sharply triangularly dilated,in the middle, except that on the 

 4th, which is only slightly dilated, and an oblique irregular spot near the middle 

 of the sides of the 2nd, black ; legs ferruginous, the hair white, the tarsal spines 

 and culcuria pale ferruginous. The hair is pale ferruginous, darker coloured — 

 more reddish — on the mesonotum and on the,apical abdominal segments. Wings 

 hyaline, largely tinged with fulvous on the fore margin, the apex in front from 

 near the radial cellules, with a smoky violaceous cloud. 9 . 



Length 15-17 mm. 



Deesa, October (Nurse). 



Head smooth, except for some scattered punctures on the front ; the thorax 

 closely, coarsely punctured, except on the apical slope of the metanotum. 



Allied to D. histronica, F., which is a larger species, has the thorax largely 

 infuscated, wants the rufous transverse stripe at the ocelli found in the present 

 species ; the abdominal yellow (at least on the 3rd and 4th segments) is not 

 continuous, but forms large lateral spots and there is no black spot on the sides 

 of the 2nd. 



Pompilid^e. 

 Pompilus benedietus, sp. nov. 

 Black, the abdomen and legs except the coxae, ferruginous, the head and 

 thorax densely covered with silvery pubescence ; wings hyaline, the apex from 

 shortly behind the end of the radius smoky, flagellum fu?cous, the scape 

 covered with silvery pubescence ; pronotum as long as the head ; metan- 

 otum furrowed down the middle at the base and apex ; the cubitus in .hind
