 pp. 267-274. 



Hippobosca equina, which has a very extended range, has recently 

 been discovered in southern Queensland. It is a constant parasite of 

 its host, and may infest a single animal in large numbers without the 

 latter manifesting any indications of discomfiture, though horses 

 unaccustomed to it evince extreme irritation when attacked. The 

 life-history is described in detail. A single puparium only is produced 

 at a time, and after its deposition, a month or more must elapse before 

 it gives rise to the adult. This fly has not been proved to be a 

 disseminator of disease.

The duration of the various stages of this flea was found to be the 

 following : — Egg, 4 days ; larva, 6 days ; pupa, 12 days. Adult 

 males lived from 2 to 6 days after emergence when in contact with the 

 normal host, while females lived from 18 to 40 days. Eggs are deposited 

 throughout the adult stage, but only after a meal of blood ; under 

 favourable conditions as many as 40 are produced during one night 

 and only two or three during the day. Females were able to survive 

 for a period up to 30 days if not brought into contact with a host from 

 the time of their emergence from the pupa ; those, however, which 

 were removed from a host after a blood meal died in one or two days. 

 Males were able to survive removal from the host for a somewhat 

 longer period. A total number of 1,027 fleas emerged in three weeks 

 from half a pint of soil from an infested henhouse.

 October 1916, pp. 263-270. 



A systematic description of the larva and of both sexes of the adult 

 of Anopheles {Myzorhynchus) hunteri, sp. n., is given. The author 

 considers that in Malaya, A. sinensis, A. barbirostris, A. umbrosus, 

 A. albotaeniatus and A. hunteri will be found to form a compact group 

 representing the Myzorhynchus section of Protanopheles, not only in 

 general but also in genital characters.
