The larvae differ in some respects from Western European and Mesopotamian 

 specimens, and appear to represent a distinct race. No differences can, however, 

 be discovered in the adults. Larvae collected in Jerusalem, Haifa and Baalbek 

 (Syria), are very uniform in structure and size and show the following obvious 

 differences from typical specimens : — Full-grown larva smaller, with distinctly 

 shorter siphon ; slightly smaller average number of pecten teeth ; antennae light, 

 instead of dark. In one case larvae were found living in a well in which the water- 

 level was 85 feet below the ground. 



The adults exhibit a certain amount of variation in the abdominal banding, in^ 

 some specimens the white bands being incomplete dorsally. 



[Culex fatigans, Wied.] 



Although this mosquito was recorded from Egypt by several of the earlier workers, 

 it does not seem to be found there. An examination of the genitalia of all males- 

 in the collection of the Egyptian Ministry of Agriculture has proved them to be 

 C. pipiens, I have been unable to find the species in Palestine or S}rria. 



Culex laticinctus, Edw. 



The larvae may sometimes be found in very large numbers in covered surface 

 wells, tanks, and similar situations in Palestine. 



The adults have been observed in quantities in tents in camps. In Egypt it is 

 found commonly at Alexandria. 



Palestine : Jerusalem ; Wadi Hamish ; Haifa. Syria : Baalbek. 



Culex univittatus, Theo. 



Distributed from Egypt to S}Tia, but never in any great abundance. The 

 larvae live in marshes and stream pools, generally away from dwellings. One 

 is liable to overlook them, as, when disturbed, they immediately leave the surface, 

 returning for only a second or two at long intervals. 



There still seems to be some confusion regarding the larval characteristics. My 

 specimens disagree in almost every particular with the description and figure given 

 in Bull. Ent. Kes. x, p. 69, 1919 ; neither do they fit in with the synoptic table 

 given in the same journal vol. iii, p. 381, Dec. 1912. I have handed some of my 

 material to Mr. F. W. Edwards, who has kindly offered to go into the matter, and 

 publish the results in a future paper. 



Palestine : Wadi Hamish ; Sarona ; Haifa. Syria : Beirut. 



Culex tipuliformis, Theo. 



Found in similar situations to the preceding. It has not, so far as I am aware,. 

 been recorded from Egypt under this name, but there is a specimen from the Fayum 

 in the British Museum collection. 



Palestine : El Afule ; Acre ; Haifa. Syria : Damascus,
