 enter series of black spots also on both wings ; the pale spot on forewing between 

 veins and T present and the brown marginal triangle on both wings. 



Head, thorax, and abdomen greyisii brown : shoulders lilac-grey, tipped with 

 black. 



Expanse of wiugs : ijU mm. 



1 S from Kassai district, Congo Free State (Taymans). 



33. Plegapteryx viridis spec. nov. 



In shape and markings exactly like P. spfimentfifn Warn, but the whole 

 forewing deep green, slightly paler and greyer, with slight lustre, beyond cell 

 and beyond outer line, which is marked by blackish green vein-dashes and edged 

 by a paler line ; inner line waved, vertical, from one-fourth of costa to one-third 

 of inner margin ; a thick darker median shade from three-fifths of costa to middle 

 of inner margin; costal edge pale grey for two-thirds, then ochreous ; cell-spot a 

 white dot in a dark diffuse ring. 



Himlwiny : with basal area deep green ; outer greenish ochreous, with greener 

 elonds ; costa broadly, and inner margin narrowly, straw-colonr ; cell-spot small, 

 white. 



Underside of forewing yellowish green, deep vellow along costa, pale along 

 inner margin, with some reddish patches along submedian fold ; outer line and 

 cell-sjiot darker; hiudwing deep yellow,. freckled with olive and brown, especially 

 along costa ; a brown spot at ape.x and curved rod-brown median line. 



Head, thorax, and dorsum dark green ; palpi, legs, and venter deej) yellow, 

 like hindwings beneath. 



Expanse of wings : 45 mm. 



1 S from Durban, Natal, March 1007 (G. F. Leigh). 



Genns Vaena AVIk. 



■Walker made this genus (cf. T roccedhiys of the Xdlnral Ilistori/ Socieh/ of 

 Glasgoiv, IST'.t, p. 341) for a species from the Congo which he called eiicleoirles, 

 the type of which is in the British Museum collection. Hitherto it has not been 

 possible to ascertain the neuration of the genus ; but lately a single S example of 

 t'ftdeoidcs has lieen received from Ogruga, Niger, whiili I have been able to examine, 

 and the neuration is here appended. 



Forewing : cell hardly half as long as wing ; discocellular oblique ; vein 2 at 

 three-fourths of cell, 3 close before 4 ; 5 from above middle of discocellular ; long- 

 .stalked with 7, 8 from the bend in subcostal ; the stem of 7, S arched and 

 ajiproximated to that of 9, 10, 11, which are also stalked together, the distal 

 ends of these three veins very fine and short, like that of VI, and all easily 

 overlooked ; hindwing, with costal and subcostal aj)proximated for half of cell ; 

 veins 3 and 7 liotli before angles of cell ; no radial. 



Cirojderijx oclnrtita Ibilhiud, F.iilom. Xcirx iv. p. 1 70 ( l.sOli), described from 

 Ogow^ lliver, is assuredly the same insect. Tlie type of this genus, viridifascia 

 HoU., I have not seen.
