Menai but not on Wizard; it is more brightly coloured than the Aldabra Phelsuma. Honegger (1966) distinguished P. abbotti menaiensis on Menai and - P. abbotti subsp. on Wizard, Grand Polyte and South Island. Insects were collected on Cosmoledo by Fryer in 1908, and forty species are recorded in the Percy Sladen Expedition Reports; these records are keyed in Table 7. Of these, only two species were Lepidoptera. Legrand's (1965) collections of Lepidoptera on Menai totalled 70 species, including 1 new genus, 24 new species, and 3 new subspecies, mostly Microlepidoptera, though some of these may need revision. B. 15. Cogan and A. Hutson made a transect of Wizard Island in March 1968, collecting insects on a transect at the narrowest point between lagoon and seaward shore. Insects were abundant in number if not in variety, but unlike Astove only the smaller species appeared to be well represented. Many of the larger species were apparently scarce, perhaps as a result of the lack of permanent fresh water. Acridid grasshoppers were present in some numbers, and females of the large Cyrtacanthacris tatarica tatarica L. were common. Butterflies and Odonata were nowhere common, and the small Lycaenid Syntarucus pirithous L. was the only species to be seen in any number. The morning visit to Wizard was followed in the afternoon by 3-4 hours on Menai, but because of rain the collections were totally unrepresentative of the fauna there. The only insect of note recognised in the collections so far is a species of Pipunculid fly, the first record of this interesting parasitic family of Diptera in the Aldabra group. Most of Legrand's collecting was carried out on Menai, and the 1968 collections may be the first on Wizard. Cosmoledo has a small faunal element that it shares with Astove and none of the other islands in the Table 7.
