 Macedonian Culicidae. ] — Bull. Soc. Path. Exot. , Paris, xi. no. 6,

The distribution of the Macedonian species of mosquitos determined 

 from material collected in 1917 is as follows : — Anopheles maculipennis, 

 Mg., very common everywhere, being practically the only species 

 captured in houses, tents, and mihtary works such as dug-outs ; 

 A. bifurcatus, L., a species usually difficult to find, though it becomes 

 more prevalent in certain places and at certain times ; A. (Pyretophorus) 

 palestinensis, Theo., widely but irregularly distributed, its larvae 

 co-existing with those of A. maculipiennis, Culex pipiens and Ochlerotatus 

 dorsalis in rivulets with clear water and herbaceous vegetation ; 

 A. (Myzorhynchus) sinensis, Wied., var pseudopictus, Grassi, fairly 

 common in lower Macedonia, its larvae co-existing with those above- 

 mentioned ; Stegomyia fasciata, F. {calopus, Mg.) ; Ochlerotatus 

 dorsalis, Mg., the larvae of which are cannibals in their later stages 

 and not particular in their choice of breeding-places, being found in 

 clear streams containing vegetation in company with Anophelines 

 and Culex pipiens, and on the other hand in pools of stagnant water 

 in the vicinity of dung-heaps and filled with Eristahd larvae, the 

 adults being found in houses together with A. maculipennis ; 

 Taeniorhynchus richiardii, Fie. ; Theobaldia longiareolata, Mcq. 

 {spathipalpis, Rond.), found in the valley of the Struma and the 

 plain of Monastir; T. annulata Schrank ; Culex pipiens, L., very 

 common everywhere ; C. hortensis, Fie. , rare ; C. mimeticus, Noe, 

 rather rare and sometimes confused with Anopheles palestinensis, the 

 larvae of the two species also co- existing ; and Uranotaenia 

 unguicuJata, Edw., the larvae of which occur with those of 

 A. maculipennis and C. pipiens in clear weed-grown streams, and 

 are cannibals. 



The larvae of U. unguiculata and of Ochlerotatus dorsalis are described 

 in detail. 



The dissection of mosquitos from various regions of Macedonia 

 discloses the fact that only about two per cent, are infective, a surpri- 

 singly small number when compared with that found in other coimtries, 

 such as West Africa. The common occurrence of malaria in Macedonia 

 is therefore explained by the fact that almost all the mosquitos found 

 in enormous numbers in the houses are Anophehnes.

 the Larva of Anopheles chaudoy&i.] — Bull. Soc. Path. Exot., Paris, 

 xi, no. 7, 10th July 1918, pp. 549-550. 



The author, referring to Langeron's description of the larva of 

 Anopheles chaudoyei, which, it was suggested, might be merely a sub- 

 species of A. turkhudi [see this Review, Ser. B, vi, p. 141] points out 

 that A. {Pyretophorus) chaudoyei was recorded in 1908 as being prob- 

 ably the principal, if not the only, vector of malaria in the oases of 

 the northern Sahara, the larval and nymphal forms being partici 

 adapted to the biological conditions of those regions. Tlii|^ 

 has on several occasions been the subject of biological st^cfel. It
