that, as bugs, fleas or lice are all very common in the civilised countries 

 of the north temperate zone, there is a considerable field open in this 

 branch of research. Such diseases as lymphadenoma and the various 

 leukoemias do not appear to have been investigated from this point of 

 view, in spite of the fact that in them the blood is affected and there 

 is a resemblance to certain tropical diseases in the enlargement of the 

 spleen and lymphatic glands. The author himself was much im- 

 pressed by a remarkable resemblance between a case of advanced 

 lymphadenoma and kala-azar, which induced him to begin the 

 feeding experiments. These experiments are described, 455 individuals 

 of Clinocoris {Chnex) lectularivs being employed, of which 184 were used 

 as controls. The results were however inconclusive, no protozoal 

 parasites being found.

The author remarks that it has occasionally been suggested that 

 various scratching birds might act as a control of Glossina by devouring 

 their pupae. The birds mentioned which live in the fly area are the 

 domestic fowl and the guinea-fowl. The former never leaves the 

 villages and therefore has little or no opportunity of finding the pupae. 

 Guinea-fowl are very numerous in Northern Ehodesia and an examina- 

 tion of the contents of the crops of 10 birds was made in the Luangwa 

 Valley. The crop of each was filled with vegetable matter, small bulbs, 

 roots, and flower buds, a few insects were found in only three 

 individuals, including Staphylinid beetles, coleopterous and lepidop- 

 terous larvae, but no pupae of any kind. Thus it is evident that the 

 guinea-fowl is a vegetable feeder in the main, and cannot be considered 

 to act as a control. 



[A similar investigation of the crops of the various Francolins, 

 Francolinus and Pteniistes spp., would be of interest. — Ed.]

The collection of blood-sucking Ai-thropods here recorded, was made 

 by the author at San Salvador, in the Portuguese section of the Lower 

 Congo Basin, at an altitude of 1,840 ft., in an undulating grass-covered 

 country. The most common fly in that region is Stomoxys nigra, which 

 is more abundant than S. calcitrans ; it is a great pest in the hot 

 season from March to May, attacking dogs, poultry and human beings ; 

 the author suggests its being the carrier of Filaria p)efstans in Africa, 

 as well as pellagra in the United States. Tabanids and tsetse-flies 

 were scarce. Stegomyia fasciata is common in the wet season. 

 Specimens of Eretmopodifes ckrysogaster were bred from larvae found 

 in an old tin. Anopheles are rare ; Cidicoides grahami is common at 

 sunset in April and May. OrnitJwdonis is common in the sandy towns 

 of Kibokolo, Ndamba and Mabaya : the natives dread the bite and the 

 subsequent fever ; some individual ticks, placed in a small cardboard 

 box Uved there for 21 months without food or moisture, thus showing 

 the danger of occupying an old camping site. Dogs are much infested
