margin of the black portion slightly curved inwards near the base ; 

 third segment with an inconspicuous small flat-triangular whitish yellow 

 spot in the middle of the posterior margin ; all the segments (except 

 the first one) with a narrow pale orange yellow band on the posterior 

 margin; pubescence orange at the sides of the two basal segments and often 

 on all the yellowish part, but frequently the tiny hairs are blackish on the 

 inner front part of the yellow spots on the first segment with a few strag- 

 glers on the rest, and sometimes black hairs extend though inconspicuously 

 over all the yellow part of the disc ; the black part of those segments 

 are shorter than the hairs on the yellow part ; a rather conspicuous 

 triangle patch of whitish yellow hairs occurs on the yellowish triangle 

 against the middle of the hind margin and also on the middle of the 

 hind margin of the fourth (or fifth) ; pubescence black on the black part 

 but at the side margins and on the discs of the fifth and sixth segments 

 always with somewhat long orange yellow hairs intermixed ; the longest 

 pubescence on the abdomen is the black fringe at the sides of the 

 third, fourth, and fifth segments. Ventre strongly convex, excepting of 

 the apex somewhat concave ; first and second segments orange yellow 

 with a large not well-defined dull brownish black spot in the middle ; 

 on the third segment the sides and hind margin are rather inconspicuously 

 orange, while on the next three segments the hind margins are rather 

 narrowly orange ; pubescence nearly all yellowish, especially as fringes 

 on the hind margins, but the segments (after the two basal ones) bear 

 some black hairs (in a specimen caught at Shisuka very abundant) on 

 the disc. 



Length : 8-iomm. 



I described the above from only three specimens presented by 

 Prof. S. Matsumura. I could hardly identify it from his description, 

 as it is too short and is not acceptable in some parts. I, however, 

 adopt the name, as the specimens are entirely the same with the type. 

 The male is not known to us. 



This species very closely agrees with the description of Ckry-
