to a point at posterior angle ; an oblique subapical streak of darker 
ferruginous, from fourth subcostal to third median nervule ; in dis- 
coidal cell usually a small faintly-marked spot nearer base than extre- 
mity ; terminal disco- cellular marking very narrow and indistinct except 
at summit. Eind-iving : ordinary basal spot and sub-basal spots usually 
distinct (the middle one of the three latter broken into three) ; ter- 
minal disco-cellular marking larger, wider, and better marked than 
that of fore-wing, partly interrupted on disco-cellular fold ; discal ray 
indistinct in its upper and lower portions, but its central part (between 
first subcostal and third median nervules) suffused, angulated, and 
usually rather conspicuous. Cilia of both wings pale ferruginous- 
rufous, immediately preceded by nervular black dots. 
$ SulphuT-yelloiv ; fore- wing luith border didler, much diminished 
hind-marginalUj ; hind-iuing ivith a scries of hlach nervidar dots only 
on hind-margin. Fore-wing : a suffusion of gamboge-yellow over basi- 
inner-marginal area, rising over lower part of discoidal cell ; blackish 
border broken into small separate spots on first median nervule and 
submedian nervure (the latter spot even wanting occasionally), and 
rarely so even as high as second and third median nervules ; the apical 
part of border varying in width accordingly. Hind-wing : a slight 
suffusion of gamboge-yellow from base along median nervure. Under 
SIDE. — Like that of but paler, except subapical oblique streak of fore- 
wing, and suffiiscd central part of discal streak of hind-wing, which are 
much darker ferruginous, more sharply angulated, and very conspicuous. 
In both sexes the apex of fore- wing is more pronounced and acute 
than in the four species above described. 
Among the drawings of some of Wallengren's type specimens 
kindly obtained for me by Mr. Chr. Aurivillius, there is a careful figure 
of that author's T. floricola, which proves to be, as I anticipated, the 
(J Desjardinsii. 
As regards T. aliena, Butler, from Madagascar, I have seen the 
type in the British Museum ; it is a very worn and faded specimen, 
and Mr. Butler agrees with me in thinking that it is in all probability 
only a small $ of Desjardinsii. 
There can be no doubt that Moschler, who (loc. cit.) carefully 
describes both sexes, is in error in associating Senegalensis, Geyer, with 
Desjardinsii, the former being entirely different in such important 
characters as the shape of the wings and the form of the border of the 
fore-wings, and belonging in fact to the Floricola group. 
The acuter apex of the fore-wings and the angulation of the hind- 
wings are alike in this species and in T. regularis, Butl., if, as I 
believe, I have correctly identified the latter, but Desjardinsii is readily 
distinguished by the very reduced border in both sexes. The speci- 
men figured on Plate lo^ exhibits the widest border yet observed in 
1 In this figure not nearly sufficient prominence is given to the principal markings of the 
under side, viz., the ferruginous subapical streak of fore- wing and upper discal streak of 
hind-wing, which are well marked in the specimen sent to the artist.
