Mr. A. G. Butler on a. Collection of 
16. Terias Bewsheri : n. sp. 
Bright sulphur-yellow : primaries with the costal border of 
the male dark grey and the margin black ; apical ai-ea black, 
beginning in an oblique, internally minutely quadrisinuate 
line from above the end of the cell, then abruptly angulated 
and transverse from the last subcostal or upper radial branch 
to the third median, where it is met by the black outer border 
forming a deep bisinuation on the median interspaces, slightly 
notched internally between the first median and internal 
veins; male with a few black scales at the end of the cell: 
secondaries with a rather narrow black border : body blackish. 
Wings below much as in T. jloricola, but the silvery spots 
towards the base of secondaries less marked. Expanse of 
wings, d 1 1 inch 8 lines, ? 1 inch 6 lines. 
A pair of this pretty species. It is most nearly allied to 
T. solifera from Angola, but brighter in colour, the female 
yellow instead of whitish, the black border, particularly on 
the secondaries, narrower. 
17. Terias brenda , Doubleday. 
Terias brenda, Doubleday, Gen. Diurn. Lepid. pi. 9. fig. 6 (1847). 
A single male, slightly smaller than examples from Ashanti, 
but otherwise identical. 
18. Terias chalcomiceta, n. sp. 
Above quite like T. senegalensis ; below differing in having 
a large transverse sigmoidal subapical patch of cupreous 
brown on the primaries. Expanse of wings, £ 1 inch 8 lines, 
? 1 inch 8^ lines. 
A single pair. 
19. Terias dentilimbata , n. sp. 
Above much like T. senegalensis , but the angles bounding 
the median bisinuation of the outer border much more acute ; 
the female decidedly paler; the primaries below with a trans¬ 
verse sinuous subapical dark ferruginous patch. Expanse of 
wings, S ? j 1 inch 7 . lines- 
A pair of this species. Its nearest ally is T. bisinuata of 
Abyssinia; its much paler female and the much more acute 
angles of the outer border render it improbable that it should 
be a variety of the preceding species. So far as I am aware, 
the borders of the wings are not markedly variable in outline; 
indeed, if such could be proved to be the case, nearly the 
whole of the species of Terias might be sunk.
