 Bewohner des mittleren und südlichen Europas, 48 des nördlichen und mittleren Europas, 

 36 des südlichen Europas, 50 des mittleren Europas, 2 des nördlichen Europas, 9 des 

 südlichen Europas und Kleinasiens, 2 Kleinasiens, 2 Dalmatiens, 2 der Alpen, 1 von Ita- 

 lien, 1 von Griechenland, 4 des mittleren Europas und der Alpen. 



Außerdem gibt er die Beschreibung von 9 Formen, deren Bestimmung er nicht 

 ausführen konnte. Bachmetjew (Sophia).

This paper contains a list of, and short notes on a large number of noxious In- 

 sects collected in the Province of Mozambique, both from the humid Northern and the 

 drier Southern portions of the province. It includes 2 sp. of Cimicidae, 6 of Anoplura, 

 20 of Mallophaga, 10 of Siphonaptera, and 70 of Diptera (17 Culicidae, 2 Chironomidae, 

 2 Simuliidae, 22 Tabanidae, 2 Trypetidae, 10 Tachinidae, 8 Muscidae including H sp. of 

 Stomoxys and 3 of Glossina, 2 Oestridae, and 56 Hippoboscidae).

This is a report of the author's travels in Southern Nigeria as travelling 

 Entomologist of the Entomological Research Committee (London! It is a sequel 

 to his reports on the Gambia (Bull. Ent. Research, II, pp. 187 — 239, 1911) and 

 Northern Nigeria (ibid., II, pp. 301 — 356, 1912): it deals entirely with blood- 

 sucking insects and other Arthropods which are, or may be, concerned with 

 transmission of disease in man and animals. In the Introduction the author 

 outlines the objects of his travels, to stimulate and assist medical officers and 

 others stationed in the various districts to make observations on, and coUections 

 of, the insects, and to record data; and to study himself as far as possible the 

 distribution of diseases and blood-sucking Arthropoda: "the first step . . . must 

 naturally be a mapping out of the various endemic centres of the different di- 

 seases, combined with a similar study of the distribution of the various blood- 

 sucking insects. Always remembering that every blood-sucking arthropod is • . . 

 a Potential disease-carrier . . ." In the following sections great stress has been 

 laid on the factors influencing distribution of the species, therefore the main 

 topographical features of the Colony, its climate and types of Vegetation, all 

 receive attention. Section I (p. 140) deals with the Geography; (a) position 

 and extent of the Colony, (b) its physical configuration, (c) its Vegetation. Under 

 this last head it is stated that there are 5 principal types; (a) tropical rain-forest, 

 where moisture is abundant and differentiation into wet and dry seasons little 

 or none; (b) fresh-water swamp forest, where the soil is permanently moist, even 

 though the dry season be rather long; (c) mixed decidüous forest, where the 

 soil is more porous and wet and dry seasons are distinct; (d) savannah forest, 

 where soil is light and the dry season very long; (e) mangrove thickets. The 

 species of Glossina are associated with these types as follows: G. palpalis is found 

 everywhere in the mangrove thickets, and is predominant in the rain-forest and 

 fresh-water swamp forest; in the mangrove thickets the specimens are larger and 

 darker than elsewhere: G. caJiginca is apparently almost entirely confined to the 

 mangrove belt: G. longipalpis is most abundant in the mixed decidüous forest: 

 G. tachitwides most likely to be found in the savannah forest. Section 11 (p. 145)
