248. Phycus atripes, Brun., nom. nov. 



Phycus niqripes, Brimetti {nee Krober, 1912), Bee. Ind. Mus. vii, 

 p. 480 (1912). 



Allied to brunneus, but quite distinct owing to the 3rd antennal 

 joint being evidently longer than the 1st and the wholly black 

 legs. Lower half of frons wholly shimmering silvery white, 

 without the large shining jet-black spot immediately above the 

 antenna? which is so conspicuous in both those forms ; 3rd 

 antennal joint cylindrical, much narrower than in the other 

 species. Median dorsal stripe faint ; abdominal bands very nar- 

 row, milk-white, only the one on the 2nd segment really distinct. 

 Legs wholly black, including coxae, which have a little bluish- 

 white shimmer. Wings clear, with a distinct blackish suffusion 

 towards tip, extending from the costa over about the distal half 

 of the 2nd longitudinal vein, reaching irregularly to the hind
