wing than that of the latter, gradually becoming acute at the base, its 

 stem about two-thirds the length of the cell ; stem of the second pos- 

 terior cell longer than the cell ; supernumerary and mid cross-veins 

 close together, the mid a little behind the supernumerary posterior 

 cross-vein about its own length distant behind the mid. Length, 

 3'5 to 4 mm. 



Habitat. Sierra Leone (800 ft.) (Major Smith). 



Observations. — Described from several females collected by 

 Major Smith. It is a very dark species, coming near A. nigripes, 

 Staeger, but can be told at once by the denser wing-scales and 

 banded palpi. The structure of the second antenna! segment is 

 very marked ; the scales are rather long and outstanding, giving 

 a tuft-like appearance.

Pyretophorus austenii, n. sp. 



Head black, with grey scales in front ; proboscis black, with two 

 broad snowy white bands, the last forming a white apex to the palpi, 

 and a third very narrow white band. Thorax brown, clothed with 

 silvery grey scales ; also the scutellum. Abdomen black, with golden 

 hair. Legs black, with apical white tips. Wings with black and 

 white patches of scales, costa with two small white spots and traces of 

 a minute third spot towards the base ; most of the veins pale-scaled, 

 but prominent black spots at base of the second posterior cell and apex 

 of lower branch of fifth long vein. 



2 . Head black, with upright snowy white forked scales in front, 

 black ones behind ; proboscis black ; palpi black-scaled, densely at the 

 base, with two broad white bands towards the apex, one forming the 

 apex of the palpi, and a third small one towards the basal half. 

 Antennae black, with grey pubescence. Thorax black, with scattered 

 broad curved snowy white scales ; also the scutellum. Abdomen 

 black, densely clothed with golden hairs ; the two lobes with black 

 scales. Legs black, the apices of all the segments, except the last in 

 the fore and mid legs, with a narrow white band ; in the hind legs all 

 the segments are banded ; ungues equal and simple, rather long. 

 Wings with rather dense Pyretophorus-like scales ; the costa with 

 three white spots, the apical one large, the second smaller, and the 

 third very small ; all three spread fairly evenly on to the first long 

 vein, which has in addition a small white spot between the two apical 

 costal ones, and another near the third spot, its base mostly white. On 

 the base of the costa is another small white spot not reaching the top 

 of the costa ; the branches of the third long vein are black at the tips 

 and bases near the fork, and there is another black patch near its base ; 

 the third long vein pale, except for a black spot near the apex, and two 

 near the base ; the fifth has two black spots near the apices of its 

 branches, a large black-scaled area in front of and including the base 

 of the fork and its stem near the fork, rest of the vein pale-scaled ; 

 the sixth has three black spots, the median one the largest ; wing-
