depressed snowy white pubescence which becomes black on the black- 

 part, and which is intermixed a very, few inconspicuous short dark 

 hairs on the upper side ; middle tibiae only at the extreme tip brown- 

 ish, densely covered with an abundant much shorter pure white 

 pubescence but the tip there are ,sotne black hairs, and bearing two 

 unequal brownish black apical spurs; hind tibiae the same as the 

 middle pair but their pubescence slightly longer and their apical 

 brownish portions slightly larger. 



Abdomen about as long as the head and thorax (including the 

 scutellum) together, slightly broader than the thorax, with the roundish 

 apex, and rather Hat. Dorsum deep brownish black with the sides 

 of the first segment and the middle part just under the scutellum vcry 

 fai ntly yellowish brown, covered with an abundant dense rather stout 

 black pubescence, and some yellowish hairs, which appear on the 

 yellowish blown parts of tin- first segment and on the middle part of 

 the second segment, and on the middle line of the third segment 

 there is a very few similar yellowish pubescence which is, however, 

 not to be discerned, while the segmentations bear no yellowish hairs 

 as Indian specimens have ; belly blackish covered with some yellowish 

 brown but somewhat shining, and covered with a dense short depressed 

 black pubescence all over. 



Length : 1S.5 mm. 



The species described above is very slightly different from 

 Indian species, being much darker and bearing less yellowish pubes- 

 cence on the abdomen, but it is quite identical with that. Only one 

 female has been collected by Mr. M. Yoshino at Kusukusu in Koshun- 

 Cho, May 2ist, 1918, and it is known that the female is a blood- 

 sucker against human being.
