A NOTE ON THE OCCURRENCE AND SIGNIFICANCE OF 

 ANOPHELINAE IN B. C. 



Seymour Hadvven. D. \'. Sci., Agassiz, B. C. 



For se\'eral years notes and obser\'ations ha\e been made (jn the 

 mos(juitoes of this jjrovince, their classification and seasonal prexalence. 

 the main object being to find methods for their control. This work has 

 been confined mainly to the Culicinae ; as far as we know the genus 

 Anopheles is represented, on the lower mainland, b\- a single species, 

 A punctipennis, say. The Anophelines are ne\er as numerous as the 

 Culicinae and are often hard to find. A punctipennis is never found in 

 large numbers, and it is only in the early spring that these mosquitoes 

 are to be seen outside: it is at this season that the}- can be found biting 

 animals. During the summer it is extremely hard to find a specimen; in 

 the autumn the}' reappear on the walls of houses and in cellars. 



The species A maculipennis, which I am recording in this paper, 

 probably has the same seasonal pre\alence as punctipennis: though it 

 has been looked for in the Similkameen and Nicola valleys, its presence 

 has not been recorded during the summer. This year it was discovered 

 for the first time at Keremeos, B. C. This portion of the province is 

 peculiarly situated and the climate is very hot and dry. 



A, punctipennis is not definitely known to transmit malaria, while A 

 maculipennis is a well-known carrier of the disease, both in Europe 

 and in America. Its presence, howe\-er, does not necessarily infer the 

 existence of malaria. Sometimes the mosquitoes are not infected. Thus, 

 in Eastern Canada. A maculipennis is still comparati\ ely common, though 

 malaria, according to rejiorts. is now of rare occurrence. In England, 

 in certain malarial districts, the disease has disappeared while the mos-
