Halobates alluaudi Bergr., Rev. d’Ent., 1893, p. 204. 
Loc. Seychelles. Mahé: Long Island. Aldabra (Fryer). In addition to the other 
localities (Chagos Islands, Amirantes, Coetivy &c.), which I previously enumerated (Tr. 
Linn. Soc., ser. 2, Zool., xiii. p. 37), where this species had been obtained, it has also 
been taken in the Red Sea, Port Sudan. At Long Island, Mahé, Mr Scott took this 
species at “low water, small ones (immature) together near shore. Big ones (mature) 
farther out.” 
Family Henicocephalide. 
74. Henicocephalus, sp. 
A single immature example of this genus was contained in this collection, and, 
though not enabling identification to be made, it must be included in the enumeration. 
Unfortunately this specimen, in a subsequent attempt to remount it, was 
irretrievably injured. 
Loc. unrecorded : the specimen was almost certainly from one of the islands of the 
Seychelles group. 
Family Reduviide. 
The total number of species belonging to the Reduviide as previously recorded was 
six only, the present enumeration brings the number to 18; one species however, 
Mascaregnasa typica Dist., previously found by Prof. Gardiner, is not contained in 
Mr Scott’s collection. 
Subfamily Emesine.
