186. Anthrax semifuscata, sp. nov. 



cJ 5 . Head : frous at level of antennae less than one-third width 

 of the head, at vertex less than half this width, blackish grey, 

 with minute bright yellow scaly pubescence, which latter also 

 covers the face ; antennas black, 3rd joint short, with long style; 

 occiput blackish grey, a fringe of small snow-white scales on 

 lateral eye-margins. Thorax black (denuded), hind corners of 

 dorsum dull reddish brown; in good specimens the dorsum, 

 anterior margin, and sides of thorax are probably covered with 

 bright chrome-yellow scaly pubescence, which extends to the 

 scutellum also. Abdomen black ; 1st segment with a band of 

 depressed bright yellow scales ; 2nd, ,3rd, 4th, and 6th segments 

 each with a basal band of similar scales, broadening towards and 

 at the sides, where it is augmented by concolorous long scaly 

 pubescence covering all the sides of the 2nd, 3rd, and 4th 

 segments ; 5th segment apparently devoid of such a band ; dorsal 

 surface of abdomen not covered by yellow scales, furnished with 

 small depressed black scales; venter black, basal half with 

 depressed bright yellow scales, concolorous scales about the tip. 

 Legs black ; femora with whitish scales on hinder side (those on 

 fore pair appear more yellowish); tibiae with some yellowish- 

 white scales ; tarsi black. Wings pale grey, basal and anterior 

 parts moderately dark brown, the colour fading away distally, 

 its approximate limit running from tip of 1st vein, just escaping 

 fork of 3rd vein, filling discal cell and bases of 3rd and 4th 

 posterior cells and filling anal and auxiliary cells; halteres 

 pale yellow. 



Length, 78 mm. 



Described from three specimens in indifferent condition in the 

 British Museum from Trincomali, Ceylon, 2. x. 1890 (type a <? ), 

 9 and 15. x. 1890 (Col Yerbury). 



Although not one of the three specimens is in good condition, 

 the species is a quite a well-marked one by the extent of inf uscation 

 of the wing. A noticeable point is the variability in the exact 

 position of the bifurcation of the prsefurca.
