is only used to economise in oil. In the centre of the receptacle a 

 night light is placed. The fleas are attracted to the light and fall 

 back into the oil and .are thus destroyed. In one locality in Morocco 

 an average of 300 fleas were caught nightly by this means. All those 

 examined proved to be Pulex initans, L. For the successful action 

 of this trap it is essential that the light afforded by it is the only source 

 of illumination, and that there should be no suitable hiding-places.

 pp. 41-46. 



This list of ticks occurring in Russia includes particulars of their 

 geographical distribution and the hosts attacked. Those recorded 

 as vectors of blood parasites are : Ixodes ricinus, transmitting 

 Piroplasma higeminum, in the north of Russia' ; Rhipicephahts bursa, 

 transmitting Babesia (P.) ovis, in the Caucasus ; M ar gar opus calcaratus, 

 transmitting P. bigemimmi and Theileria anniilata, in Transcaucasia ; 

 Hyalomma aegyptium, probably transmitting Nuttalia equi, in south 

 Russia ; Dermacentor retiailatus, transmitting P. caballi, in central 

 Russia, and Nuttalia ninense in Saratov ; A rgas persicus, transmitting 

 Spirochaeta gallinarum and 5. anserina, in South Russia ; and Ornith- 

 odoros tholozani, transmitting S. persica to man, in Transcaucasia.

The species of Phlebotomus in the El Kantara-Biskra region are : 

 P. 'papatasii, Scop , P perniciosits, Newst., P. sergenti. Parr., and 

 P. minutus var* africanits, Newst. 



The more important ^ those species from the point of view of Oriental 

 sore are P. papatasii arwi P. minutus africanus. These species appear 

 to be least numerous between the end of June and the end of August. 

 P' papatasii generally occurs in the vicinity of human habitation 

 or near animals, but these conditions do not apparently have the 

 sanie attractions for P. minutus africanus. Both species have a 

 marked preference for dark, sheltered corners of rooms, etc. The 

 proximity of vegetation, such as gardens, appears to favour intensive 

 breeding of P. papatasii either as a result of the increased humidity 

 .or other conditions favouring multiplication. This species will attack 

 fowls and pigeons but could not be induced to feed on geckos, and is 

 apparenthi' exclusively a feeder on warm-blooded vertebrates. P. 

 minutus var. africanus, on the other hand, feeds almost entirely on 

 geckos, etc., and should it become infected with leishmaniform bodies 

 from these reptiles, 'it does not transmit them to man. 



The examination of both these species for the presence of intestinal 

 flagellates proved negative. Subsequent experiments have, however, 

 proved P. papatasii to be a transmitter of Oriental sore [R.A.E.,
