which are more abundant than the Uce, can be destroyed by cleaning 

 the poultry houses thoroughly with boihng water, creosote or a 

 coal tar solution. Fumigation with sulphur or formaldehyde is also 

 recommended.

 East Africa. — Jt Trop. Med. & Hyg., London, xix, no. 17,

In July and August 1915 many cases of acute dermatitis due to 

 contact with a small beetle occurred at Nairobi, and the fact is recorded 

 as a similar epidemic occurred in West Africa, at Leopoldville [see this 

 Review, Ser. B, iv, p. 15]. These specimens were identified by the 

 Imperial Bureau of Entomology as Paederus crebripunctatus, Epp.

In experiments made on Calliphora erythrocephala and Lucilia 

 caesar, the flies were allowed to oviposit on raw meat. Eggs of the 

 former species laid on lst-2nd September hatched on 2nd-3rd ; the 

 larvae pupated after from 10 to 16 days, and adults emerged in from 

 8 to 13 days later. L. caesar differed from C. erythrocephala in that in 

 some cases the pupal stage was prolonged to 24 days. Some eggs and 

 larvae were killed by a temperature of 100'4° F. Later in the year 

 the larval period extended over several weeks, and all larvae died at the 

 beginning of November. Oviposition did not take place on dry meat. 



Eggs of Musca domestica were laid on banana, either under the loose 

 skin or in crevices of the pulp. Hatching took place on the day 

 following oviposition, although half the eggs were kept at a temperature 

 of 100-4° F. and the remainder at from 40° to 60° F. The food of the 

 larvae consisted of banana and a mixture of bread, casein, sugar and 

 water. The same mixture was also found suitable for C. erythrocephala 

 and L. caesar. The duration of the hf e-cycle up to the time of emergence 

 of the adult varied from 9 to 14 days at 100-4° F., and from 23 to 25 

 days at from 40° to 60° F.

The investigations recorded in this paper were carried out at a house 

 in Kent during August and September 1915. A breeding place for 

 flies was furnished by a manure heap near the house. Measures were 

 taken (1) to prevent breeding by treating farmyard manure (a) in the 

 manure heap with tetrachlorethane, 1 part in 20 of water, every four 

 days ; (6) in the garden with green oil and soil at the rate of 1 part of 

 oil and 40 of soil to 100 square feet of surface ; (2) to destroy flies by
