surra, a form of trypanosomiasis of which the causative agent, Tr//- 

 panosoma evansi, is beheved to be capable of dissemination by more 

 than one species of Tahanus. Tlie Egyptian Expeditionary Force 

 stationed there in 1918, however, had but few cases of surra among 

 their camels, and these were by no means certainly contracted in 

 Palestine. 



No species of Pangonia was taken, but 16 species of Tahanus were 

 collected, of which nearly half are new. Attention is directed to the 

 pursuit of a fast travelling motor car by two species. This habit does 

 not seem to have been previously recorded, though in Africa the 

 attraction for Glossina of moving vehicles or animals has been noticed 

 on more than one occasion. The chase is, however, confined to short 

 distances, so that the establishment of a motor route through a local 

 Tabanid area would not be likely to have much effect on distribution. 



The species dealt with include Chrifsops pimctifera, Lw., which is 

 apparentlv the only representative of its genus in Palestine ; Haemato- 

 poia sewelli, sp. n., H. minuscularia, sp. n., H. minuscula, sp. n., and 

 H. innominata, sp. n., to which a key is given ; Tahanus decor us, Lw., 

 T. alexandrinus, Wied., T. insccutor, sp. n., T. gigas, Hbst., T. mendicus, 

 Villen., T. lunatus, F., T. nemoralis, Mg., T. eggeri, Schin., T. autum- 

 nalis, L., T. regularis, Jaenn., T. rupinae, sp. n., T. arenivagus, sp. n. 

 T. accensus, sp. n., T. leleani, sp. n., T. pallidipes, sp. n., and T. dalei, 

 sp. n., a key being given to these.

The mosquitos dealt with in this paper were collected in the neigh- 

 bourliood of Basrah, Lower Mesopotamia, between October 1918 and 

 February 1919, mostly in the cultivated belt lying between the river 

 banks and the desert ; this area is intersected by numerous creeks and 

 irrigation canals and also contains many pools and swampy areas. 



Anopheles stcphensi. List., appears to be the chief malaria carrier 

 of the district, numbers of larvae and adults being found from October 

 to December, the larvae occurring cliiefly in the clearer pools of the 

 cultivated area. A. puJcherrimus , Theo., seems to have been much 

 reduced in numbers by anti-malarial work, but many larvae were found 

 in pools near the edge of the desert in October. These sometimes 

 occur with A. stephensi, but generally prefer weed-growm, stagnant 

 and more brackish water. A. hgrcanus, Pall, (sinensis, Wied.), is 

 not often seen in the Basrah area, but a few were caught in the 

 marshes beside the river. 



Culex fatigans, Wied., was abundant in pools; C. pipiens was less 

 frequent and was not seen before January : C. modestus. Fie, 

 C. tritaeniorhi/nchus, Giles, and C. tipuliformis, Theo., w^ere found in 

 small numbers. StegGmyia fascial a , F.. was seldom seen and no larvae 

 were found ; Ochlerotatus dor sails, Mg., was common, both in the 

 cultivated area and on the edge of the desert, adults and larvae 

 occurring from December to February. Theohcddia lonjiareolatay 

 Macq., was frequently found in the larval state in January and Feb- 

 ruary, chiefly in the deeper pools ; the pupa usually remains about
