Bat-bugs and Bed-bugs. — Jl. Dept. Agric. Union S. Africa, Pretoria, 

 iv, no. 3, March 1922, p. 209. 



The question has recently been raised whether the bug found asso- 

 ciated with bats is distinct from the one infesting human habitations. 

 Cimex lectidarius (bed-bug) specialises on man, and has become adapted 

 to his habits ; C. piloseUiis, characterised by longer hairs and antennal 

 differences, specialises on bats. C. rotundatus is the common bed-bug 

 in some tropical countries, as in parts of India, and is recorded as a 

 poultry pest also. It is stated to occur in Africa. Animal parasites 

 generally confine themselves to a particular host, and are unable to 

 exist for long on any other animal, although they may occasionally 

 bite others. C. lectidarius has been fed experimentally on mice, and 

 has even transmitted disease in that manner, but there is no evidence 

 that the mouse is anywhere its normal host. It is probable that the 

 bug commonly associated with bats will bite man occasionally, but it 

 is unlikely that it could subsist as a human parasite. The common 

 bed-bug does not shelter in human hair ; it is therefore unlikely to 

 hide in bat fur, and in any case would probably drop off when the bat 

 took wing.

Trop. Med. & Parasit., Liverpool, xvi, no. 1, 31st March 1922, 

 pp. 47-50, 1 fig. 



Phlehotomus trinidadensis, sp. n., is described from Trinidad, this 

 being the first authentic record of the occurrence of this genus from the 

 West Indies.

Glossina haningtoni, sp. n., is described from South Kamerun, 

 occurring only in the neighbourhood of Basho. G. palpalis, R.-D., 

 and G. pallicera. Big., were taken in the same locality, the latter being 

 apparently the commonest species. 



Waterston (J.). A Contribution to the Knowledge of Sandflies. — 



Ann. Trop. Med. & Parasit., Liverpool, xvi, no. 1, 31st March 

 1922, pp. 69-92, 1 plate, 7 figs. 



The investigations here described were carried out in Macedonia 

 on three species of sand-flies, Phlebotonius papatasii, Scop., P. minntns, 

 Rond., and P. perniciosits, Newst. In the summer of 1918 there was a 

 severe outbreak of sand-fly fever in and around Janes ; P. papatasii was 

 by far the most abundant species and is thought to be the most likely 

 vector of the disease. This point can, however, only be settled by 

 direct experiment. The bionomics of the flies are described. In studying 

 their habits great difficulty was experienced in keeping them alive until 

 suitable apparatus for handling them was improvised. The appliances 

 used are described and iflustrated. Details are also given of the 

 technique employed. 



Apparently mating takes place after the females have had a blood 

 feed, the process of which is described. No males were found to bite. 

 A full feed on an empty stomach occupies from four to four and a half 

 minutes ; the whole gut may be cleared in five days, but sometimes
