tlie lateral depression is wide and deep, deep black, atid 

 bearing some stout longitudinal keels. There is a deep 

 depression between the apex of the })Ostscutelluni and the base 

 of the median segment ; the depression is black at the base 

 on the bottom and on the lower part of the apex ; the middle 

 of the raised part projects above the level of the postscutellum ; 

 the centre is raised, is very smooth and shining; the sides 

 are obliquely depressed from it ; the segment has a rounded 

 slope from the base at the top to the apex and is coarsely and 

 closely punctured ; the centre of the segment from the raised 

 central part to the apex is bordered on either side by a stout 

 keel, which diverges roundly towards the apex ; inside of 

 this in the centre is a narrower keel, which splits in two 

 shortly before the middle ; the space enclosed by these keels 

 is deep black and is stoutly transversely striated, but not so 

 strongly and more closely than on the central area ; the lateral 

 are* are closely reticulated, the keels bounding them form a 

 triangle ; the spiracular area at the base is closely and rather 

 strongly punctured ; its apical half bears seven or eight stout 

 oblique keels, which become stouter and more widely sej)arated 

 towards the apex. The apex of the median segment and the 

 nietapleurjB behind the coxse arc deep black. PropIeura3 

 closely punctured ; the depressed middle is deep black, 

 smooth, except for a few oblique striations on the lower side. 

 Mesopleurte closely punctured ; the apex is deeply furrowed 

 and crenulated ; the base of the metapleurse deep black, 

 broad at the top, becoming narrowed below; the depression is 

 deep and much ^\ ider above than below ; below the middle 

 are two stout keels ; the rest of the metapleur^e closely and 

 strongly punctured ; the apex with some indistinct striations; 

 the mesopleura3 black under the wings and down their base, 

 and the base of the mesosternum is black ; the apex is slightly 

 curved and projects somewhat triangularly at the sides ; the 

 centre is deeply furrowed. Wings fusco-violaceous, lighter 

 in tint towards the base ; the costa, stigma, and nervures 

 Lhick ; the areolet is narrowed at the top, being about one 

 lialf of the length of the space bounded by the recurrent and 

 liic second transverse cubital nervures ; the recurrent is 

 received shortly beyond the middle of the areolet. The four 

 anterior tarsi are infuscated towards the apex ; the hinder 

 black, rufous at the base. Petiole elongate, longer than the 

 second segment ; the middle of the post|)etiole is de])ressed at 

 the base and strongly longitudinally striated, the sides jjunc- 

 tured. The second segment in the middle is strongly longi- 

 tudinally striated, the striations reaching to near the apex and 

 becoming finer there. Gastrocoeli wide, deep, smooth, except 

 lur a few irregular braken stria? at the base ; the third segment
