scutellum very long, nearly erect, brownish, about the margins with a 

 very few black hairs intermixed. Pleurae blackish, somewhat shining, 

 slightly obscured by yellowish dust, the upper half of the meso-pleurae, 

 the upper portion of the sterno-pleurae, prothorax, and meta-pleurae, 

 as well as the ptero-pleurae densely covered with yellowish tomentum ; 

 the pubescence on the pleurae like in the female. 



Wings slightly greyish but quite hyaline, with much darker 

 .markings ; the brown fore border at the apical part well-defined, broad- 

 er, distinctly reaching to the apex of the wings ; the basal brown 

 portion much wider, extending to the basal thirds of the basal cell ; 

 second basal cell at the lower third along the postical vein distinctly 

 shaded ; cross-band more extended below, hardly reaching to the 

 margin of the wing, leaving the centre of the discal cell and lari;e 

 upper part of the postical cell where they are faded and somewhat 

 clear, in the specimens from Japan very short as in the female but 

 intensively darker, and very slightly faded at the centre of the discal 

 ceil. 



Colour of legs in the specimens from Formosa as in the female, 

 and in the specimen.; collected in Japan conspicuously darker, with the 

 fore coxae and basal half of the hind femora blackish, the former at 

 the basal half of both sides with an unwell-defined yellowish spot and 

 beneath near the apex yellowish the pubescence much longer and 

 denser, the hind femora mostly short and yellowish ; but the underside 

 mainly bearing very long somewhat tawny blackish hairs, the pubescence 

 on the hind tibiae more than twice as long as in the female and at 

 the inner base with much fewer very short yellow hairs intermixed. 



Abdomen gradually narrowed towards the apex and somewhat 

 pointedj the colouring and markings as in the female, but the lateral 

 stripe much narrower and almost always not conspicuously interrupted 

 at tlie segmentation ; in the Japanese specimens the extreme lateral 

 margins with a narrow blackish stripe from the third segment to the 

 apical segment, the stripe being gradually broadened behind, and the
