ON THE MOSQUITOS OF MACEDONIA. 



By James Waterston, Lieut. K.A.M.C., 

 Entomologist to the Malaria Commission, Salonika. 



This report, which is of a preliminary nature, deals with the species of Culicidae 

 met with in Macedonia .by the British Malaria Commission during the latter half of 

 - 1917. The collections of the Commission have been augmented by material forwarded 

 from time to time to the Malaria Enquiry Laboratory, Salonika, by various Medical 

 Officers and others in the field. While engaged in working out these and other blood- 

 sucking Arthropods, I had the privilege of examining, through the kindness of 

 Dr. Joyeux, of the Mission Antipaludique, samples of species taken within the areas 

 under French control. As our reports are to appear almost simultaneously, and as 

 my colleague has devoted special attention to the larval morphology of these 

 insects, I have confined myself here mainly to the adults, and field notes. I desire 

 to thank heartily the following officers for material and notes supplied — Majors 

 Bissett and Armour ; Captains Boyd, Candler, Peacock and Carnwath. I have also 

 been indebted in many ways to the kindness of Lt.-Col. C. M. Wenyon, O.C. the 

 Malaria Enquiry Laboratory. For the work of identification the Trustees of the 

 British Museum (Nat. Hist.) have afforded every facility, and in this connection 

 my best thanks are due to Mr. Lang of the Museum Staff. Again, as on many another 

 occasion, it is a pleasure to acknowledge the assistance ungrudgingly rendered by 

 Dr. G. A. K. Marshall, Director, Imperial Bureau of Entomology. 



Natural Enemies of Mosquitos. 



Though no examinations of the stomach contents of birds were made, it was 

 fairly certain from their actions that swallows (Hirundo, Delichon and- Cotile) 

 destroyed numbers of mosquitos. During the scrub and grass fires initiated as a 

 measure of mosquito control these birds might be seen . moving in . hundreds 

 backwards and forwards across the line of the advancing fire. Of the work of other 

 species it is impossible to speak definitely. Some of the smaller waders, resident
