of the abdomen, white. Four front legs red, the middle femora 

 inf uscated, their tarsi black ; the hind legs black, the coxaa 

 bright red, tarsi white ; except at the base. Wings hyaline, 

 the nervures and stigma black. 8 • 



Face coarsely rugose, obscurely striated in the middle, 

 the clypeus sparsely punctured. Front in centre stoutly 

 striated. Basal depression of metanotum with 3 stout, longitu- 

 dinal keels ; behind this irregularly obliquely striated and 

 rugose ; the rest of metanotum rugose, the base with oblique, 

 converging strife, the centre at the apex irregularly transverse- 

 ly striated. Apex and central depression of propleuraB stoutly 

 striated ; the meso- except at the apes, closely, rugosely, 

 longitudinally, the meta- closely, rugosely, striated. 



The middle of the mesonotum at the end of the central 

 lobe, is irregularly reticulated ; the scutellar depression is deep, 

 narrow find striated in the middle. Median segment covered 

 with white pubescence. Petiole brownish and dilated at the 

 base ; hind tibiae and tarsi densely covered with dark, short 

 pubescence. 



This species differs from the others in having the alar 

 areolet longer and narrower, the scutellum flatter and the 

 abdominal petiole tuberculate at the base and shortly beyond 

 the middle. It differs also from the known males in having 

 the face and clypeus white. 



Pharzites, gen. nov. 



This genus is closely related to Lactolus from which it may 

 be separated by the under noted characters : — 



Cubital nervure in hind wings broken above the middle ; apex of 

 clypeus obliquely, isemicircularly depressed, labrum large, 

 long, narrowed towards the apex. > Pharzites. 



Cubital nervure in hind wings broken distinctly below the 

 middle; clypeus not depressed in front, labrum indistinct. 



Lactolus, Cam. 



The malar space is slightly larger; the tarsi are spinose ; 

 the median segment is not so distinctly or regularly striated ; 

 the antenna) are slender, broadly ringed with white and closely 

 pilose, especially towards the apex; the transverse median 

 nervure is received distinctly behind the transverse basal ; the
