This report enumerates 9 species as known from the islands of the W. Indian Ocean, 

 Of these 2 are new to science, and 2 new genera are described. 6 of the spp. are Orien- 

 tal, 1 is a Madagascar sp., and 2 spp. are only known from the Seychelles.

A note on the coulour of the larvae and the breeding of the flies: the larvae were 

 found on young pine-trees aflfected by 2 spp. of Äphis. H. Scott (Cambridge).

The writer had near his house (in N. Nigeria) several trees of a species which 

 exudes quantitiea of milky latex when injured. One of these was infested with great 

 numbers of the Coccid Ceroplastes egbarum Cockerell. This tree had a powerful attrac- 

 tion for Tabanidae of several spp., both J and $. They came to it in the day-time, and 

 crawled over the larger branches, which were covered with old scales; but they did 

 not Visit the young growing shoots, which bore many fresh scales and were frequented 

 by swarms of ants. So strong ,was the attraction of the tree, that a pony tethered a 

 few yards away was quite unmolested by the flies. H. Scott (Cambridge).

This paper deals with 24 spp. from the Seychelles, and 3 from Aldabra, collected 

 by the Percy Sladen Trust Exp. It is remarkable that Limnophilini and Tipulidae longi- 

 palpi are quite unrepresented. 23 of the species ai-e described as new to science. A 

 table is given showing the geographica! relationships of a number of the species: as 

 far as can be seen, the fauna as a whole appears to be more closely connected with 

 the African than with the Oriental fauna, but some isolated forms show very curious 

 relationships. H. Scott (Cambridge).

A small cicatrix was produced in some larvae of Liparis dispar in the mid- 

 ventral line between the 9^^ and 10*^ abdominal Segments. As a result those 

 genital structures which develop internally, but which normally come to the sur- 

 face at the pupal moult, remain imprisoned, and form a mass in the interior of 

 the abdomen: these parts are the penis (= aedeagus and vesica) and the penis- 

 sheath, which develop strictly internally, and the clasps, formed from an inva- 

 ginated part of the 9**^ abdominal segment. On the other hand those parts which 

 develop externally (from Segments 9 and 10) are normal in the malformed spe- 

 cimens. H. Scott (Cambridge).
