new Gcnr.ra of IchiicunioniiliO. 379 



the jiarts at the sides of the scutcllum and postsciitclhm, a 

 sciniciicuhir mark on the suprainedian area, continued down 

 the posterior median area to the apex of the sei^ment, a broad 

 band in the middle of the propleuriu, a complete band on the 

 top of the meso[)leura3, the base and lower side of the mcta- 

 plenra', the a|)ex of the mesosterimm, and the metasternum, 

 black. Seutellum pyramidal, the base and apex with an 

 oblique slope, stron^^ly and closely punctured, thickly covered 

 \\'\i\\ short fuscous iiair ; the postscutellum with an oblique 

 slope to the base and apex ; punctured, covered with short 

 glistening white hair ; the depression at its side wide, strongly 

 striated. The base of the median segment has an obliquely 

 rounded sloj)e, black ; the black dilated backwards in the 

 middle; thesupramedian area is broadly rounded at the base, 

 slightly longer than broad, its apex bounded by a stout keel, 

 which bulges slightly backwards; the other areje are not 

 defined ; the teeth are large, longer than broad, rounded at 

 the apex. The pleura closely punctured, the meta- more 

 coarsely than the others. Areolet wide at the top, not much 

 narrower than the space bounded by the recurrent and the 

 second transverse cubital nervures ; the recurrent is broadly 

 curved and is received shortly beyond the middle; the trans- 

 verse median nervure is received distinctly in front of the 

 transverse basal. The legs are uniformly coloured yellow, 

 except for the posterior trochanters, which are black; tiie 

 tarsi are closely and strongly spinose. The base of the 

 petiole is smooth, shining, impunctate, the apex closely 

 punctured ; there is a black longitudinal line down its middle; 

 the base of the second segment broadly, of the third more 

 narrowly, black ; closely jninctured ; the gastrocrcli shallow, 

 distant from the base of the segment, finely punctured, rufous 

 in the middle. 



XesTOJOPPA, gen. nov. 



Antennae short, thick, dilated and compressed beyond the 

 middle ; tlie joints of the flagcllum not much longer than 

 broad. The central area of the median segment commencing 

 at the middle of the segment. Labrum projecting. Seu- 

 tellum not much raised, its sides not keeled. Occiput mar- 

 gined. Areolet 4-, or indistinctly o-angled ; the recurrent 

 nervure is received between the middle and apex. Abdomen 

 with seven segments, smooth and shining ; gastrococli shallow. 

 liCgs stout, the apices of the tarsal joints spinose. Colour 

 yellow, marked with black.
