tpargin ; the two followings with whitish grey tomentose bands on the 

 broad (but still narrow) hind margins, these bands becoming broader 

 in the middle above and bearing white or very pale orange pubescence ; 

 the last three segments with the very narrow greyish white hind 

 marginal bands ; pubescence on the sides slightly longer than on the 

 disc. Ventre black, similarly dusted and haired as in the dorsum but 

 less shining and the two basal segments wholly dusted with whitish 

 grey, while the whitish bands are broader and never swollen about 

 the middle, and the seventh segment without whitish bands but with 

 some stout long erect black bristles which hardly extend up to the 

 preceding segment. 



Length : 9.5-10 mm. 



Described from six females (well preserved), one from Rono 

 (March) in the southern part of Formosa, and others from Naniwa 

 (July 25th.) of Giran District in the northern part of the same. The 

 specimen from Rono is much more identical with the type than the 

 species noted by Miss Ricardo in the Supplementa Entomologica, No. 

 Ill, p. 64, 1914, and quite the same as a number of specimens found 

 in the Federate Malay States. 



This handsome species probably varies rather greatly in the 

 number ot white bands on the abdomen (from two to five), and in the 

 colouring of the subcallus (from reddish yellow to dark brown) ; but 

 it is distinguished from the preceding allied species, by the narrow 

 frontal stripe, by the brownish wings, by the two distinct broad white 

 abdominal bands, by the rather shorter pubescence on the legs, by 

 the dark palpi, and by the two differently coloured thorax. 



A female rested on my left arm and pierced it about two 

 o'clock in the afternoon. In this case her piercing was rather severe, 

 but the effect did not continue for wholly a day.
