Wings fnlvons. Foreicing marked with black at the extreme base and 



along costa for 2 or 3 mm.; a black spot extending 2 or 3 mm. on costa at nearly 

 one-third ; a black ajiical patch of abont the same extent as in fentiis, containing a 

 more extended and irregnlar white jiatch tliau that sjiecies, the black remaining 

 onl_y as : a broad oblic^ne band from costal margin half-way to jMsterior margin, 

 constricted at end of cell by a triangular encroachment of the ground-colour, a 

 moderate apical patch continued to beyond M^ as a rather narrow distal band, and 



a projecting prong from this latter along M' to near the costal band. [liiiilwiny 



with a narrow black border, broadest at aj)ex, its posterior half consisting of three 

 large, somewhat round-edged blotches whose centres lie on veins W', M' and M-, 

 and which are only very narrowly connected on the margin itself 



Uuder-surface the same. 



Ndzooimi, Lagos district, Southern ^Nigeria, June 10, 11)11 (W. A. Lamborn). 

 Type in coll. Oxford Museum. 



Colour and structure (except antenna) as in the East African tenuis Butl. ; 

 a pair of short median spnrs present on the hindtibia. 



1(3. Ergavia costimaculata spec. nov. 



S, 50 mm. Antenna pectinate, the branches very short — only abont the 



length of diameter of shaft. Hindtibia with a single spnr. Forewing without 



areole, both wings with DC^ strongly incurved, M' separate. Head, body and 

 wings light wood-brown, marked with dark reddish-brown. Face, palpus, autennal 

 shaft and dorsum of abdomen coarsely spotted ; vertex, thorax and wings clearer, 

 except front of thora.x, which is wholly dark. 



Forewing with the usual raised black cell-mark ; a large costal blotch at base, 

 reaching nearly to first line, a triangular one from first line to cell-spot and a 

 smaller subapical ; lines black, the first from costa beyond one-fourth, forming 

 a very strong outward curve in cell, and a strong outward angle on SM^, thick 

 from costa to aiiil-cell, thick-spotted at base of M-, in fold and on SM-, otherwise 

 very indistinct; second line weak in parts, starting from a blackish spot on costa, 

 following about the same course as in most of the genus, thick on most of the 

 veins ; subterminal line pale, dentate, extremely indistinct except against the 

 subapical blotch, on either side of R-, where it is accompanied proximally and 

 distally by dark spots, and liehind M-, where it is similarly accompanied ; termen 



with large dark dots between the veins ; fringe irregularly dark-sjiotted. 



llindicing with the raised discal mark black ; the black postdiscal line stronger 

 thaji on forewing, with slight tootli outward on V>, two stronger, even ones on SC- 

 and K', a regular sinus between the radials and blunt teeth at W anil M' ; traces of 

 a much weaker, irregular, diffuse brown line nearer base, crossing end of cell ; the 

 area between the two lines, except cnstally, filled uj) witli red-brown ; some dark 

 spots proximally to the very faint subterminal line in costal iialf of wing and 

 between M- and margin. 



Underside of forewing suffused with reddish, postdiscal line of both wings 

 traceable, chiefly by dark vein-dots, that of forewing distinct from M" to margin ; 

 both wings with small black cell-mark and with the subterminal blotches present.
