tbe convej'ance of plag'ue and leprosy to human heinj^s; the foUow- 

 iug- is a list of these g-enera : — Myonyssus, Leiofjndthus {= Liyo- 

 iiyifsufi), Dermanyssus {= Lii)onyssoides), Laelaps, aud Haevio- 

 gainaiu^. Dernianyssus avium lias been known to attac-k human 

 beings, and species of Laelaps and LeiognatJius have been found 

 on man ; Neumann reciords a case in which a house was infested by 

 Laelaps stahidaris, Koch, Avhich seriously affec^ted the health of 

 one of the inmates. 



Three new species of Gamasid mites are described, viz., Der- 

 i/uinyssus muris, taken from rats {Mus rattus) in the cities of 

 Madras and Colombo; D. aegyptius, taken from Acomyscahirlnus, 

 Ai'i-icaiithis sp., and Mas ratius in Egypt; i\ud Leiognatli u.f< haaoti, 

 taken from Mus norvcgicus in Egypt. Laelaps eeJiidninus, 

 Berlese, is recorded from Mus norvegievs in London and the 

 United States, and from Mus ratius in Colombo.

This is the finst of a series of papers in which it is proposed to 

 give the results of a detailed study of the individual species of the 

 Anopheles mosquiios of the Federated Malay States. In the 

 present paper the egg, the newly-hatched larva, the mature larva 

 and the pupa of Anopheles tessellatus, Theo., are described.

A systematic revision, which has already been anticipated by 

 the work of Stanton and Alcock [see this Review, Ser. B, pp. 5 

 and 131]. The author regards Lophoscelomyia and Patagiamyia 

 as synonymous with Myzorhynchus, in which he recognises five 

 Malayan species ;• — sinensis,, harhirostris, umhrosus, alhotaeniatus 

 and asiaticus. Revised descriptions are given of these species.

The present memoir deals entirely with the comparative 

 anatomy of the proboscis in the blood-sucking Muscidae, par- 

 ticularly Musca nehulo, Philaem-atomyia gurnet, P. lineata, P. 

 insignis, Haematohia. irntans, Stomoxys calcitrans, Lyperosia 

 minuta, and Glossina suhmorsitans. Conclusions are drawn as to 

 the evolution and relationships of the Muscidae. They are 

 probably all derived from a MuscaAike ancestor; the first steps 

 in the evolution of the blood-sucking- habit can be seen at the
