338 Insecta. 



a non-endemic portiou made up of species from various regions, these non-endemic 

 species being found mostly in cultivated country, and sometimes occurring also 

 in neighbouring coral-islands (the Amirantes); (IV) the fauna of Aldabra is pre- 

 dominantly Madagascan and African. These conclusious are borne out by the 

 following details: 



Lamellicornia: the 25 species represent 19 gen«ra: 19 spp. were found in the Sey- 

 chelles, 7 in Akhibra, only 1 being common to both groups. 6 of the Seychelles species 

 are endemic, including 2 endemic genera {Ferissosoma and NesohopUa n. g.j: the 13 non- 

 endemic species include Madagascan, African, South-Asiatic and Cosmopohtan forms. 

 Of the 7 Aldabra species 5 are typically Madagascan, wbile 2 (Cetoniini) are ^jerhaps 

 peculiar but very closely related to African species. 



Adephaga: the 30 species belong to 2i) genera: 14 spp. were found in the Seychelles, 

 17 in Aldabra, only 3 being common to the two groups and 1 of them {Cicindela melan- 

 cholica Fabr.) being represented by 2 distinct races. Carabidae are conspicuously absent 

 in the Seychelles endemic forests, and probably no truly endemic species exist there: 

 the 9 species found in the cultivated parts show predominant African and Madagascaa 

 affinitieti: all are -winged except 1, Anillus sp., blind and wingless. 2 out of the 4 Sey- 

 chelles Dytiscidae are endemic and appear to be isolated forms. In Aldabra the Ade- 

 phagous fauna is predominantly Madagascan and African, including also 2 Cosmopolitan, 

 species. 



Several new species discovered in the Seychelles endemic forests have peculiar ha- 

 bitats. 2 Aphodiini {Oxyomus palmarum and Ataenius Jodoiceae) were found only in the 

 humus between leaf-bases of endemic palms. Copelatus pandanorum, a true water-beetle,, 

 was found only in the water between leaf-bases of endemic Pandanus (see pp. 225, 226, 259).

 tomologist, Bd. 45, Heft 7, S. 189—191, Textfig., 1912*. 



This larva was found alive in S. England in May. At first sight it appears to 

 consist of head -|- 4 thoracic -|- 23 abdominal segments. In reality the number is that 

 normal for Coleopterous larvae. The head is pseudo-bisegmental, the prognathous mouth- 

 pieces being separated from the rest by a transverse division. The first thoracic segment 

 is brown and hard like the head, the other two are soft and pale, as are the abdominal 

 segments. The intersegmental membranes of the abdominal segments are greatly elon- 

 gated and exposed, appearing like additional segments: thus, V^ abdominal segment con- 

 sists of two divisions, segments 2 — 7 consist each of three divisions, segment 8 of two, 

 while segment 9 is single; this makes up the 23 apparent divisions, while segment 10 

 is concealed under segment 9. 



The larva was found in very dry, fine, and pure sea-sand, on the coast. In capti- 

 vity it burrowed in the sand wheu this was wetted. In its movements it is utterly un- 

 like other Elaterid larvae, being very quick and agile : it holds its anterior parts slightly 

 raised from the ground, and moves them quickly from side to side, the mouth-parts being 

 in coustaiit Vibration; the posterior parts are trailed along the ground and move forward 

 with peristaltic movements. H. Scott (Cambridge).
