to a point at posterior ang-le ; an oLlicpie subapical streak of darker 

 ferruginous, from fourth sul)costal to third median uervule ; 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. Ilind-wing : 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 nervriles) suffused, angulated, and 

 usually rather conspicuous. Cilia of both wings pale ferruginous- 

 rufous, immediately preceded by nervular black dots. 



$ Sulphur-yellow ; fore-wing with border duller, much diminished 

 hind-marginalhj ; hind-iving with a scries of Uach nervular dots only 

 0)1 hind-margin. Fore-iving : 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 sid)ap)ical oblique streak of fore- 

 wing, and suffused central part of discal streak of hind-iving, which are 

 much darker ferruginous, more sharply angidated, and very consjncuous. 



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. fioricola, which proves to be, as I anticipated, the 

 $ 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 Scnegalensis, 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 Fioricola group. 



The acuter apex of the fore-wings and the angulation of the hind- 

 wings are alike in this species and in T. rcgularis, 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 10^ 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 s'treak of 

 hind-wing, which are well marked in the specimen sent to the artist.
