the pubosceiice on the apical two segments is black ; tlio 

 hair on the ventral segments is ciarkor-coloured than on the 

 dorsal. 



The median segment is furrowed in the middle from the 

 basal area; the clypeus is flat, with its sides roundel; the 

 pleurai opaque, the metapleuras at the base obscurely striated ; 

 tiie second abdominal segment is slightly depressed and has 

 a fine transverse furrow ; the second transverse cubital 

 nervure is roundly curved outwardly, and the mesopleurse at 

 the tubercles are thickly covered with white pubescene;. 



Comes nearest to the Ceylonese xV. rastica, Sm. It has 

 the general coloration and appearance of X. ihoracica, Sm. 



HaUctus hihorensiSf sp. n. 



Black, the basal segments of the abdomen with a brownish 

 tint; the hair white, on the underside of the tarsi fulvous; 

 the basal area of the median segment has a few irregular 

 longitudinal striaB; the basal two segments of the abdomen 

 with a transverse narrow furrow near the base ; the wings 

 hyaline, the stigma testaceous ; the first recurrent nervure is 

 interstitial ; the second cubital cellule at the top is slightly 

 longer than the third. ? .

Face and cljpeus strongly but not closely punctured ; the 

 apex of the clypeus is imj)unctate, except for a few elongate 

 punctures, and is fringed with long fulvous hairs ; the front 

 and vertex are closely punctured and ojiaque, except behind 

 and in front of the ocelli ; the hair is griseous, darker on the 

 front and vertex. Mesonotum shining, sparsely but dis- 

 tinctly punctured ; there is a narrow furrow down the centre 

 on the basal half and another on either side opposite the 

 tegnlaj ; the base at the commencement of the central furrow 

 is slightly but distinctly incised ; the base has a vertical slope 

 and lias a transverse pilose furrow near the middle. Scu- 

 tellum shining, sparsely punctured at the base ; the post- 

 scutellar region is thickly covered with long white hair. The 

 basal area on the median segment is not clearly defined, at 

 the base it bears a few irregular longitudinal stri* ; the apical 

 slope is bounded above by a rounded, laterally by more distinct 

 oblique keels ; the apical half in the centre is deeply furrowed. 

 Pleurae covered with white hair. Wings hyaline, the stigma 

 tootuceous, the nervures darker ; the second cubital cellule at 

 the top is fully longer than the top of tiie third; the first 

 recurrent nervure is interstitial, the second is received near
