hair. Scutellum pimctured and thickly covered with fuscous 

 hair. Postscutellum very smooth and shining, glahrous, 

 deeply and widely foveate laterally. The central depression 

 on the median segment is bordered behind by a short stout 

 keel. Tlie rest of the segment is coarsely rugosely punctured ; 

 the areola is open behind and is longer than broad; the 

 posterior median and lateral apical areas coarsely reticulated, 

 longitudinally in the middle, more coarsely transversely at 

 the sides ; the teeth stout, black. Propleurae above punctured. 

 ISIesopleurse shining, the black upper part shagreened, more 

 coarsely at the apex below, the upper part raised, the lower, 

 next to the sternum, also projecting, but not so strongly. 

 Metapleurse strongly obliquely striated, less strongly at the 

 base. Petiole smooth and shining, the apex triangularly 

 dilated, the base of the second segment strongly longi- 

 tudinally striated ; the gastrocceli elongate, smooth on the 

 outer side, the apex testaceous and separated from the rest 

 by a stout transverse keel ; the base of the petiole is stoutly 

 keeled down the middle and less stoutly at the sides.

Hab. Khasia Hills. Coll. Rothney. 



Very similar in form and coloration to X. trilineata, Cam. 

 (Ann. & Mag. Nat. Hist. ser. 7, vol. vii. p. 378), but may be 

 known from it by the form of the scutellum, which has the 

 sides largely bordered by leaf-like expansions from the base 

 to the apex, by the depression at the base being bordered 

 laterally by a stout keel, by there being three areae on the 

 base of the median segment, and by the gastrocceli being 

 stoutly longitudinally striolated. 



Yellow, suffused with fulvous ; the ocellar region, the 

 vertex in the middle, the front broadly, a broad line on the 

 middle of the mesonotum extending from the base to shortly 

 beyond the middle, the sides near the tegulae, the scutellar 

 depression, the depression at the base of the median segment, 

 the middle of the areola, the. posterior median area entirely, 

 the middle of the propleurae, the base of the mesopleurae and 

 the upper part below the tubercles, a mark over the middle 

 coxae, and the base and lower side of the metapleurae, black. 

 Vertex finely punctured, the front very smooth and shining. 

 The face and base of the clypeus with large shallow punctures. 

 Apex of mandibles black, the base covered with soft white 

 hair ; before the apex on the lower side with golden hair. 

 Mesonotum closely punctured, dull yellow, suftused at the
