 This paper contains a key to the genus Spaniopsis, the females of 



which have blood-sucking habits. The species dealt with include ; 



S. tabaniformis, White, from Tasmania and S. vexans, Ferg., S. clelandi, 



Ferg., S. marginipennis, Ferg., and S. longicornis, Ferg., from New 



South Wales.

This bulletin is designed to emphasise the importance of measures 

 against the house-fly [Musca domestical The life-history of the 

 insect is described and preventive measures considered, chiefly from 

 the point of view of individual action, though community action, 

 which alone can hope to eliminate the nuisance, is touched upon. 

 Individual effort can secure considerable protection ; cleanliness and 

 sanitation are of first importance, and screens for doors and windows, 

 particularly those of kitchens and similar places, are recommended. 

 Various traps are described, the main principle of them all being a 

 cone entrance with a small opening at the top. One of the best baits 

 is bread and milk. Tainted meat is not particularly attractive, while 

 it brings blow-flies from far and wide to become an additional 

 nuisance. Fly-papers are useful at times, though the poisonous ones 

 are dangerous. A teaspoonful of formalin in a pint of water or diluted 

 milk is an effective poison, while castor oil, with or without the addition 

 of a drop of croton oil, has also been recommended. Fly " swatting " 

 unless done with discretion may produce results more insanitary than 

 the flies themselves. Fumigation with powdered sulphur (2 lb. to 

 1,000 cu. ft. space) is sometimes desirable. As measures against 

 the larvae, manure should be spread thinly over the fields in preference 

 to being in heaps. Otherwise it should be kept in properly constructed, 

 shaded bins. Chemical treatment is too expensive for general use, 

 but the use of hellebore and borax is mentioned. The maggot trap 

 [R.A.E., B, iii, 134] is described at length.

Mange of the legs in fowls is caused by an Acarid, Sarcoptes mntans. 

 In cases of slight infestation the legs should be soaped with a soft brush 

 and after drying they should be coated with paraffin. If the disease 

 is of long standing a hard brush should be used and the legs painted 

 with an ointment consisting of 4 oz. of flowers of sulphur, 6 oz. of lard 

 and 1 oz. of benzene. This paste should be applied 2 or 3 times at 

 intervals of 3 to 4 days. The soil and perches, etc., should also be 

 disinfected. 



Symbiotic mange may be treated by the application of a lukewarm 

 solution consisting of 10 drops of nicotine to If pints of water. 



The lice, Menopon biseriatum, M. pallidum, Lipeurus heterographus 

 and Goniocotes gigas {abdominalis), on fowls may be controlled by 

 dusting the plumage with a 10 per cent, naphthaline powder. As
