Two species of Hispinae have been found in this arcbipelago, both in the highest 

 and dampest parts of tbe endemic mountain-forests, and possibly attached to the ende- 

 niic palma. They belong to two new genera. The first of these, Nesohispa, seems to be 

 intermi'diate betwen Xifhispa (which is found in Madaga-^car and New Guinea) and 

 Brontispa (Mascaieue Islands, New Guinea, Philippine Islands, etc.) The second genus, 

 Bhabdolohispa. resembles a genus (Coelccnomenodera) known from Madiigascar and frora 

 West Africa. Bhabdotohispa has a remarkable sensory pit in the terminal Joint of the 

 antenna. H. Scott (Cambridge).

This rt'port on the material collected in the islands of the W. Indian Ocean, by 

 tbe Percy Sladen Trust Expedition in 190ö and 1908 — 9, enumerates 23 s^jecies of Hydro- 

 philidae and 16 of Histeridae from those islands, 14 species and 3 genera being de- 

 scril)ed as new. Of the Hydrophilidae, 13 terrestrial and 5 aquatic forms were found in 

 the Seychelles group. Among the terrestrial forms are the three new genera, one of 

 which is wingless and is certainly endemic. It is represented by two new species found 

 one in each of two i.slands: they are found only in very small areas on the summits 

 of the highest peaks, between damp dead leaves on the ground. The second new genus, 

 is represented by three new species in the Seychelles. but has representatives also in 

 Assam and Engano Island (near Sumatra), and is closely allied to a genus known from 

 the Hawaiian Islands. The third new genus is closely-allied to one known from Central 

 America and from Japan. The remaiuing land-inhabiting Hydrophilidae are probaldy 

 all imported, and the aquatic forms are eitber very wide-spread or very closely-allied 

 to Madagascan and African forms. Turning to Aldabra, 9 species were found in that 

 island, and its Hydrophilid fauua has only 3 very wide-spread species in common with 

 that of tue Seychelles. Its remaining 6 species are purely Madagascan and African. 



15 of the Histeridae were found in the Seychelles group, the remaining one species 

 collected being a Madagascan form from the coral-islands of Cargados. 8 are known 

 only from the Seychelles and may be endemic, but several of these have affinities with 

 Eastern species. Among the non-peculiar forms are Madagascan, Eastern, and very wide- 

 spread species, and one that is known also from the Hawaiian Islands. An interesting 

 ca>e of wing-reduction in the seaweed-inbabiting coast-species Halacritus algariim is 

 recordfd 



It is Seen then tiat in tbe more interesting peculiar portion of its Hydrophilid 

 and Histerid fauna tbe Seychelles has a decided Eastern affinity, interesting in connection 

 with the similar affinity found in its Pselaphidae, Phasmidae, and in certain other portions 

 of its fauna. H. Scott (Cambridge).

 In: Trans. Linn. Soc. London, 2id Ser, Zool., Bd. XVI, Heft 1, S. 93—116, 1913. 



This is a systematic repurt on tbe material of these faniilies collected by the Percy 

 Sladen Trust Expedition in the islands of the W Indian Ocean. The Heteroceridae 

 are represented by a single Madagascan species, found in Aldabra: the Nitidulidae 

 by 27 species, 14 of which are de^cribed for the first time, representative of 8 genera. 

 It is difficult to say which of the new species are confined to the Seychelles, until there 

 is a greater knowledge of Nitidulidae from other parts of the woiid. Some of these 

 peculiar species have affinities with Madagascan, others with Ceylonese forms (e. g Cilloeus). 

 A number of very wide-spread or quite cosmopolitan forms are present (e. g. Carpophilus 

 dimidiatus and C. hemipterus), and have no interest from the point of view of the special 

 Seychelles fauna. The moHt characteristic feature of the Nitidulid fauna is the large 

 representation of minute forms of Cyliocephalus. This genus is represented in all parts 

 of the World, but the ö forms of it pre.-<ent in the Seychelles are all hitherto unknown 

 from anywhere eise, and all are described from long series of apecimens. The author 

 remarks that no other fauna presents quite this characteristic.
