12 PERCY SLADEN TRUST EXPEDITION 



Platte Island, with a light wind from the N.W. after 10 days' calm. India, Ceylon, 

 Burma, Andamans, Java. 



61. Magulaba imparata Walk., Cat., p. xv, 1777 (1858); Hamps., Moths Ind., 

 iii, p. 26. 



Magulaba. mcestalis Walk., Cat., xxxiv, 1126 (1865). 



Seychelles : Mahe, numerous ; Praslin ; St Anne. Africa, India, Ceylon, Borneo, 

 Korea, Japan. 



62. Simplicia inareolalis, n. sp. (Plate 1, hg. 8, neuration of wings). 



In markings and general appearance this species exactly resembles >S'. inflexalis Guen. 

 In a series of 18 specimens however there is no trace of an areole and I therefore describe 

 it as new, though it is doubtless a local development of the widely spread S. inflexalis. 



Seychelles : Mah6 : Silhouette. 



63. Nodaria externalis Guen., Delt. et Pyr., p. 64, 1854. 

 Aldabra, 4 ^, 11 ?. S. Africa, Mauritius, India, Ceylon, Japan. 



64. Hydrillodes perplexalis, n. sp. (Plate 1, fig. 9, palpus.) 



$. Head, thorax and palpi dull fuscous brown : fore wing fuscous brown with grey 

 tinge ; an indistinct waved sub-basal line ; a median black spot in cell ; a grey brown 

 waved postmedial line bordered externally by a narrow lighter line. Distal third of wing 

 suffused with dark grey brown ; submarginal line represented by a series of lighter dots. 

 Hind wing grey brown ; an indistinct semilunar discal dot and medial line. 



$. Marked as in $ but the whole insect is suffused with a red brown instead of 

 a grey brown. Expanse 28 mm. 



Structurally this species falls in Section II. A of Hampson's classification of the genus 

 in " Fauna of British India " but in markings it exactly resembles H. i-e])ugnalis ; on this 

 account a short description only is necessary. 



Seychelles, '6$, 6?. 



65. Hydrillodes sp. ? 



Two very fragmentary specimens of a Hydrillodes were obtained in Aldabra, which 

 are very small {expanse 14 mm.) and structurally require a new section near sect. II. A. 

 They are almost certainly new but from the material in my possession it is quite impossible 

 to describe them. 



66. Progonia patronalis (Walk.), Cat., xix, p, 873. 



7 specimens ; the discal dash varies from chestnut to black. 

 Seychelles ; Mahe. India and Ceylon to Australia. 



67. Rivula dimorpha, n. sp. (Plate 1, fig. 10, $.) 



$. Head, palpi, thorax, abdomen, pale ochreous ; antennse darker. Fore wing pale 

 ochreous, more or less irrorated with brown scales which are less prevalent over the basal 

 area ; a short brown basal dash on costa reaching cell ; a brown antemedial line or fascia 

 from near inner angle to costa near middle, usually interrupted or much narrowed before 

 costa, but always expanded again on costa to form a short brown dash ; a black dot at
