FRYER— THE LEPIDOPTERA OF SEYCHELLES, ETC. 



5. Ilema decreta (Butl.). 



Lithosia decretaB\it\.,Tvaa\s. Ent. Soc. London, 1877, p. 351 ; Kirby, Cat. Het. p. 325. 

 Eema decreta Hamps., Cat. Lep. Phal, ii, p. 176. 

 Aldabra, 31 specimens, ^ and ?. Borneo, Australia. 



Mahensia, nov. gen. (Plate 1, figs. 2 and 3). 

 Proboscis fully developed. Palpi slender, upturned, reaching vertex of head. 

 Antennae in $ ciliated. Tibial spurs moderate. Fore wing with the costa evenly 

 arched ; vein 2 from just beyond middle of cell ; 3 and 4 stalked from lower angle of 

 cell ; 5 absent ; G and 7 stalked from near upper angle of cell ; 8 and 9 absent or 

 coincident with 10; 10 from upper angle; 11 from after middle of cell approaching 

 closely the distal end of 12. Hind wing with vein 2 from cell at f ; veins 3 and 4, 

 coincident, from lower angle ; vein 5 from middle of discocellulars ; veins 6 and 7 

 coincident from upper angle ; vein 8 from cell at ^. This genus is perhaps a development 

 of Siccia of Section iii. (Hampson, Cat. Lep. Phal., ii, p. 392), which it resembles in the 

 structure of the antennae and palpi. Type M. seychellarum. 



6. Mahensia seychellarum, n. sp. (Plate 1, fig. 2, $ ; fig. 3, neuration of wings). 



$. Head and thorax whitish. Abdomen dark grey ; terminal segment with a small 

 tuft of fuscous hairs. Fore wing white, the costal edge at base grey ; a blackish patch 

 on costa at ^, reaching cell ; another at |, larger, subtriangular, outwardly curved and 

 reaching vein 4 ; blackish suffusions near apex, near centre of outer margin and on inner 

 margin just before outer angle, the two former not leaching margin of wing ; sometimes 

 a black angular dash near inner angle ; a black spot on discocellulars ; another at point 

 of origin of vein 2 ; a third at base of wing. Underside grey with a patch of reddish 

 scales (androconia) covering distal end of cell. Hind wing grey, with a patch of reddish 

 androconia over distal end of cell. Exjyanse 16 mm. 



Seychelles: Silhouette, 1000 ft., ix. 1908, 2 $. 



7. Philenora subfusca, n. sp. (Plate 1, fig. 4, $). 



$. Head, thorax, abdomen and wings dark red brown, with a purple tinge ; 

 antennae, legs, anal tuft, lighter. Fore wing with a very indistinct dark antemedial 

 line ; a second, postmedial, just beyond discocellulars ; a black somewhat elongate spot 

 in cell and a second, circular in shape, on discocellulars, the intervening area being light 

 fuscous ; sometimes a light fuscous patch between the ante and postmedial lines near 

 inner margin ; an indistinct light area at apex and at outer angle, representing perhaps 

 the edge of a subterminal line ; traces of a series of marginal spots. Hind wing dark 

 fuscous, with a purple tinge. Expanse 19 nnn. 



This species appears to come in Section ii. B of the genus (Cat. Lep. Phal., ii, p. 509) 

 and is abundantly distinct from other known species. 



Seychelles: Silhouette, 1000 ft. viii., ix. 1908, 4 $. 



8. Utetheisa elata (Fabr.), ab. diva (Mab.) ; Hamps., Cat. Lep. Phal., iii, p. 480. 

 Seychelles: thirteen specimens from Mah^ and Silhouette, 800 — 1000 ft., all of 



ab. diva. Fletcher obtained two specimens of the type on Mahd.
