6 PERCY SLADEN TRUST EXPEDITION 



Assumption, 1 ? of type form, R. P. Dupont, 1910. Also Madagascar, Mauritius, 

 Comoros. 



9. Utetheisa 'pulchella (Linn.); Hamps., Cat. Lep. Phal., iii, p. 483. 



Fletcher obtained this species on St Anne I., but it is apparently unrepresented in 

 the present collection. Two ? from Aldabra may be this species, but are more probably 

 U. pulcheUoides. 



Throughout the old world, temperate, subtropical and tropical regions. 



10. Utetheisa pulcheUoides Hamps., Ann. Mag. Nat. Hist., ser. 7, xix, 1907, p. 239. 

 Seychelles: Silhouette, 2 specimens; Bird I., 8 specimens; a $ from Silhouette has the 



red markings replaced by yellow. Aldabra, 2 specimens. Recorded from Formosa, New 

 Guinea, North Australia, Solomon Islands. 



11. Utetheisa lactea, subsp. aldahrensis Fletcher, Trans. Linn. Soc. London, ser. 2, 

 ZooL, vol. xiii, p. 2G8. 



A long series from Aldabra, all of which are more or less strongly marked with red 

 and black ; examples from Assumption resemble those from Aldabra. A single specimen 

 from Cosmoledo resembles subsp. aldahrensis, except that the fore wings are suffused with 

 light fuscous.

12. Rhodogastria aldahrensis, n. sp. (Plate 1, fig. 5, $). 



$. Head and thorax ochreous ; palpi ochreous, tinged with crimson above, each joint 

 with a terminal black lateral spot. Antennae fuscous, basal joint crimson below. Vertex 

 of head with black spot ; tegulse, shoulders, patagia pro- and meta-thorax with paired 

 black spots, which may be obsolete. Legs and abdomen cream coloured, more or less 

 tinged with crimson above. Fore wing light fuscous or ochreous ; two black points at 

 base ; a large discal semihyaline patch in and below end of cell and in the interspaces 

 beyond it, extending to near outer margin, between veins 2 and 4 ; a smoky black apical 

 suffusion extending from costa near junction of veins 6 and 7 to the outer margin between 

 veins 3 and 4. Hind wing hyaline, with a narrow cream-coloured border along outer margin. 

 $ as $, but with less crimson on abdomen and legs. Expanse : $ 36 — 42 mm. ; $ 42 mm. 



This species is most nearly allied to R. astreas var. madagascarensis Bois, from 

 which it may be easily distinguished by the entire absence of a discoidal fascia and by 

 the absence of black spots on the abdomen. It is a smaller and more uniformly 

 ochreous insect. 



Aldabra, 1 $. Assumption, 2 ^, 1 $. 



Noctuidse. 



13. Chloridea armigera (Hiibn.); Hamps., Cat. Lep. Phal., iv, p. 45. 

 Assumption, 6 specimens. World-wide. 



14. Chloridea assulta (Guen.) ; Hamps., Cat. Lep. Phal., iv, p. 47. 

 Assumption. Hampson (Ann. Mag. Nat. Hist., ser. 8, vol. i, 1908, p. 481), records 



this species as being taken by the " Valhalla." All my specimens seem referable to the 

 same species. W. Africa, India, Ceylon, China, Australia.
