INSECTS DIRECTLY OE INDIRECTLY INJURIOUS TO MAN 

 AND ANIMALS IN MOZAMBIQUE, EAST AFRICA. 



By C. W. Howard, B.A., F.E.S. 



The following is a list o£ the more important insects collected in the Province 

 of Mozambique (Portuguese East Africa) and which in some stage of their 

 existence may be harmful to men or animals. During the writer's stay in 

 Mozambique it was impossible to make a complete survey of that immense colony, 

 but as much collecting was done as opportunity offered and this list may be 

 considered a fairly representative one. 



The main centres of collecting were in the Lourenco Marques and Grazaland 

 districts, which are at the southern extremity of the area belonging to the 

 " Companhia de Mozambique," of which Beira is the chief town ; but collections 

 were also made at the northern border of this same district, along the 

 Zambesi River ; in the Zambesia district itself, extending northward from the 

 Zambesi along the coast ; and from the mouth of the Zambesi to the Shire 

 River. A few insects were sent in from Mozambique, Tete and Inyambane 

 districts. Consequently representatives of the insect fauna were obtained from 

 the humid northern portions of the Province, which resemble Eastern Central 

 Africa as to climate, and also from the drier southern portions in which the 

 conditions resemble closely those existing in the eastern half of British South 

 Africa. 



The following gentlemen have kindly assisted me by determining the different 

 groups of insects for me : — Hon. N. Charles Rothschild, the Siphonaptera ; 

 Prof. L. GL Neumann, the Pediculidae and Mallophaga ; Mr. E. E. Austen, 

 who determined many of the Tabanidae, Muscidae and Culicidae ; and 

 Dr. L. 0. Howard, Chief of the United States Bureau of Entomology, who 

 secured the determination of the greater part of the Culicidae and other 

 Diptera. 



Occasional mention will be made of specimens collected in the Transvaal and 

 other parts of South Africa. 



Order Hemiptera. 

 Family Cimicidae. 



Cimex lectularius, L. This insect is found in most parts of the Province in 

 small numbers, indeed they are so rare that it was difficult to secure specimens. 

 It is a veritable pest in the Transvaal and Southern Rhodesia, especially in the 

 towns and villages. 



Cimex rotundatus, Sign. Three specimens of Cimex, two from houses in 

 Lourenco Marques and one from a native hut at Mopea on the Zambesi River, 

 have been considered as probably belonging to this species. They resemble 

 C. rotundatus in the character of the prothorax but not otherwise. As this 

 species is found in India, between which country and the East Coast of Africa
