its development in fowls, which, are in the habit of feeding upon 

 termites, and adults were reared experimentally in clean fowls fed 

 with infected termites. It is supposed that the termites, of which 

 only workers have been found infested, swallow the eggs, which 

 hatch within the body, the larva finding its way to the coelomic cavity. 

 It has not been definitely ascertained whether there are three or four 

 larval stages in the evolution of this Filaria, the probable number 

 being four, and it seems to be beyond doubt that the second ecdysis 

 takes place in the fowl.

The Anoplura listed from material in the laboratory collection 

 and in the Transvaal Museum include the majority of the species that 

 are hkely to be found on domestic birds and animals in South Africa. 

 New species include : — -Haematopinids, Polyplax ivaterstoni, on 

 two species of rat ; P. arvicanthis, on the striped mouse, Arvicanthis 

 pumilio ; Menoponids, Colpocephalum harrisoni, on a bustard {Otis sp.) 

 in Angola ; Pseudomenopon rostratvla, on Rostratula capensis (painted 

 snipe) ; Trichodectids, Trichodectes caffra, on a bush cat {Felis caffra), 

 and T. genetta, on a genet {Genetta ludia).

Descriptions are given of the larvae of the following mosquitos : — 

 Mucidus scatophagoides, Tlieo., found in a rain-water pool and probably 

 predaceous upon other larvae ; Ochlerotatus hirsutus, Theo., found 

 in the summer months in rain pools, hoof- holes, etc., in roads ; 

 0. argenteopunctatus, Theo., found in pools along a river bank in the 

 summer months ; Culex tipuUformis, Theo., taken from streams ; and 

 C. salisburiensis, Theo., taken in pools and occasionally in streams. 

 Larvae of Cidex decens are recorded from a coal mine in the Transvaal 

 where they were fomid at a depth of 300 ft. below the ground level.

From female examples taken in April and March 1919 around 

 Lantana scrub in Ceylon, it is obvious that Toxorhynchites minimus, 

 Theo., belongs to this genus and not to Megarhinus in which it was 

 originally placed.
