Hy tmk Hon. W. ROTHSCHII-D and K. JORDAN. 



1. Praedora marshalli tropicalis subsjiec. nov. 



S. Major qnain P. m. marshalli R. & J. (11)03), corpore et alis anticis colore 

 rn'oTO inagis extenso, palpornm segmento Patqnc alarum posticarura dimidio basali 

 pallidioribus. 



Long. al. ant. "-'3 mm. 



3 cJ(J from Uganda, in Mus. Brit. 



The iipperside of the thorax and abdomen more extended black than in 

 P. m. mar.shalli R. k J., Xoc. Zool. ix. Snppl. p. 50. tab. 5. fig. 16. S (1903), from 

 Mashonaland and N'Gami, the patagia being almost entirely deeji black. The first 

 segment of the palpi has the ventral edge and the inside cream-colour, the base of 

 the second also being more or less of the same colour. The blackish rings on the 

 hindtibia are somewhat more distinct than in P. m. marshalli. The interspace 

 between the two discal lines of the forewing is more or less filled in with black, so 

 that a large black or blackish patch surrounds the apex of the cell, joining the 

 antemedian lines below the cell ; upon this patch or cloud follows a fawn-coloured 

 band, which is diffuse on the proximal side and bounded by a black and irregularly 

 undulate line on the discal side ; before the margin a row of black anguliform spots ; 

 the apex suffused with black, the fringes spotted with grey. Hiiulwing clayish buff 

 ])roximally, blackish distally, with an indistinct blackish baud on the disc and 

 another before the margin. 



2. Polyptychus spurrelli spec. nov. (Text-figs. 1 and 2.) 



S. P. retuso R. & J. (1908) simillimus, sed thorace sine stria fusca mediaua 

 et armatnra copulatrice valde di versa distinguendus. 



Long. al. ant. 33 mm. 



1 S from Bibianaha, Gold Coast, 70 miles N.W. of Dimkwa, TOO ft., October 17. 

 1909 (H. G. F. Spurrell), in Mus. Brit. Named in honour of the collector. 



The body and wings are drab grey both in this species and retusus R. & J., 

 iVor. Zool. p. 259. n. 3 (1908), and the markings of the wings are almost exactly the 

 same in the two species. In spurrelli, however, there is no blackish median stripe 

 on the head and thorax, and the forewing is a little broader, with the apex a 

 trifle less produced than in retusus. Fore- and midlegs as in retusus (hindlegs 

 wanting). Abdomen without spines, scales narrow. 



Forewing, on the upperside, with a small but conspicuous black-brown subbasal 

 dot; between this dot aud the snuili clayish discocellular dot three undulate lines 

 curving costad in front, on the disc ihrec similar Hues followed at some distance by 

 a fourth, all accentuated at the costal and inner margins ; a row of faint submarginal 

 dots commences with a rather large subapical, costal, somewhat diflf'use and triangular 



blackish sjiot; fringes fuscous. Hindwiug darker than forewing, with an elongate 



blackish jiatch in front of thealidominal margin, a small bluckish anal spot jireceded 

 by a faint, short, anguliform line and a row of extremely weak submarginal dots.
