The lateral mucro is small, triangular, rounded on the outside, the central has 

 the sides raised. Ocelli in a curve, the hinder separated from each other by 

 double the distance they are from the eyes. Tubercles pale yellow. 



A distinct little insect, not easily confounded with any of the known Indian 

 species. 



Oxybelus forticarinatus , sp. nov. 



Black, the antennal scape, base of mandibles, the apex of pronotum, tuber- 

 cles, a mark on the sides of the scutellum, oblique, oval, wider than long, the 

 lateral squamae, and broad transverse lines on the sides of the basal 4 or 5, ab- 

 dominal segments, the apices of the 4 anterior femora, the underside of the 

 anterior, the greater part of the 4 anterior tibiae, the base of the posterior and 

 the tarsi, yellow ; the coxae and the apical two-thirds of the hind tibiae black, the 

 4 hinder trochanters and femora rufous ; flagellum dark rufous. Wings hyaline, 

 the nervures dark fuscous. Scutellar lamina large, twice longer than wide, 

 roundly narrowed towards the apex, which has a A — shaped incision ; the co- 

 lour is rufous, yellowish round the edges ; down the centre is a strong longitu- 

 dinal keel, from which radiate some obscure striae. $ and $ ,

 Deesa, March (Col. Nursed. 



Head below the ocelli densely covered with silvery pubescence ; the vertex 

 less closely pilose, strongly, closely punctured ; the front less closely punctured. 

 Apex of clypeus with 3 short, stumpy teeth. Base of mandibles broadly yellow, 

 the middle rufous, the apex black. Pronotum smooth, the apex carinate, the 

 sides oblique. Mesonotum closely punctured, the scutellum more shining, more 

 strongly punctured, but with the punctures much more widely separated and 

 with a keel down the centre ; the lateral laminae triangular, longer than they are 

 wide at the base, the outer side rounded, the apex ending in a curved point ; 

 the apex of the scutellum is depressed and has a stout central and 3 short, stout 

 lateral keels. On the apical slope of the metanotum, on the upper half, is a 

 triangular area, its apex being smooth, depressed, the rest being roughened ; on 

 either side is an oblique, narrower, triangular area ; the sides are strongly 

 keeled. Mesopleurae somewhat strongly punctured, the metapleurae obliquely 

 striated, the striae clearly separated. Abdomen strongly punctured, the penulti- 

 mate segment more strongly than the other ; the sides of the last raised, bor- 

 dered by a smooth line, its apex transverse ; there may be 2 more or less 

 distinct yellow line on the 5th segment ; the apical yellow lines are not so 

 widely separated as the basal. 



The amount of black, yellow and red on the legs varies, as does also the 

 strength of the puncturation. 



This species comes near to O. squamosus, Sm., the two may be separated by 

 the form of the scutellar process ; in squamosus there is no stout central keel 

 and its centre is broadly raised ; in the present species there is down its centre 

 a stout longitudinal keel and the sides are raised ; i.e., there is a depression
