in an antiseptic fluid in a container kept under a fly-proof cover, and fly- 

 traps must be placed in the room. Instead of traps, plates may be 

 half-filled with a mixture containing 9 oz. of milk, 9 oz. of water and 

 two spoonfuls of formol, a shce of bread being placed in the plate for 

 the flies to settle on. The second bulletin refers to the method of fly 

 control originated by Levy and Tuck [see this Review, Ser. B, ii, p. 72] 

 in which a heap of manure is placed on an open-work platform standing 

 in a shallow pan of masonry which drains into a liquid- manure pit 

 fitted with a pump enabling the heap to be wetted as required. To 

 ensure an efficient destruction of the larvae, the height of the manure 

 heap must not be more than about 5 feet 6 inches, and to deal with 

 1,060 cubic feet of manure, a platform of 21| square yards surface 

 would be needed. Cheapness and eSiciency are the main points of this 

 svstem. The third circular enumerates the measures required to 

 destroy or drive away flies in stables and cow-houses.

Observations on the seasonal breeding of Anopheles quadrimacvlattts 

 and A. jninctifennis made from May to October 1915 gave the following 

 results : — A count made from 26th May to 26th June showed 2 

 A. qnadrimaculatus and 628 A. punctipennis. The same region 

 surveyed from 16th August to 20th September showed a very different 

 distrikition of species, viz :— Of 600 individuals, 78 per cent, were 

 A. quadrimacidatus, 20 per cent. A. ptinctipennis and 2 per cent. 

 A. crucians. A further examination, made from 26th to 30th October, 

 showed 19 per cent. A. quadrimaodatus and 71 per cent. A. puncti- 

 pennis. The A. punctipennis larvae were, if anything, less abundant 

 than in September, so there must have been a marked decrease of 

 A. quadrimaculatus, which appeared to have a distinct predilection 

 for ponds, in preference to marshes and running water. A survey of 

 the Anophehnes found in houses in the day-time showed that 

 A. quadrimaculatus was frequently met with in inhabited houses, as 

 W'cU as in other situations. A. punctipennis was very rare in inhabited 

 houses, though often met with in outhouses, etc.

In this report are included a few records of insect pests of man and 

 animals. Advice against an invasion of the Wipipohoscid, Stenoptenjx 

 hirundinis, was asked from near Christiania. Ornithomyia avicularia 

 was found to occur very commonly on ptarmigan. Other household 

 pests were Phyllodromia {Blatta) germanica, Blatta americana which 

 was very troublesome in a cargo of corn from the Mediterranean, 

 Glyciphagus domesticus, and Chelifer cancroides, the latter having 

 invaded a house from a neighbouring hay-loft. 



Cimex {Acanihia) lectularius was reported from Christiania and 

 ■elsewhere.
