This differs from the next genus in no constant character but the 

 straight nervellus, which is neither geniculate nor intercepted. 



PRISTOMERIDIA ALBESCENS, sp. nov. 



c 9 c? A very pale stramineous, dull and apparently debilitant 

 species with the mandibular apex, a line connecting ocelli, a vitta on 

 each of the three mesonotal lobes, [scutellar fovea, frenum, speculum, 

 hind tarsi, base and apex of their tibiae, inner side of their coxae and 

 more or less of anus, indefinitely brunueous or nigrescent ; flagellum 

 infuscate with joints of its basal half apically flavidous and the first 

 pale beneath. Face short, shining and finely punctate, longitudinally 

 elevated centrally and discreted from the convex and apically rounded 

 clypeus ; mandibular teeth of equal length, cheeks normal. Meso- 

 notum dull and finely shagreened, its apex prominent and abruptly 

 declived but with superficial notanli ; scutellum convex, ueai'ly circular 

 and whitish, only basally margined ; metathorax obsoletely scabricu- 

 lous, both its transcarinae distinct with very indistinct and sub- 

 triangular areola ; petiolar area trans-strigose. Abdomen linear, 

 somewhat dull and evenly shagreened throughout, with the thyridii of 

 second segment elongate and genital valvulae exserted. Legs slender ; 

 hind femora stout with an acute tooth, followed by a series of 

 serrations, slightly beyond centre. Wings ample and hyaline with 

 nervures and the very broad stigma black ; basal continuous through 

 median ; nervellus neither geniculate nor intercepted. 



The 9 shows remarkable transition to the Cremastides, and suggests 

 that the present tribe cannot long be retained distinct therefrom. Its 

 hind femora bear no more than the slightest trace of a tubercle, 

 followed by a series of very fine trans-striae. In other respects it 

 differs from the male in nothing but its black and subaciculate two 

 basal segments, nigrescent metanotum and centre of the third and
