The bug, Triatoma protrada, Uhler, found in the nests of Neotouia 

 fuscipes, harbours in its digestive tract, Trypanosoma triatonuie, sp. n., 

 with blood which is possibly derived from the rat. Crithidial and 

 trypaniform stages, which are probably later forms in the life-cycle of 

 the trypanosome, were also present.

This bulletin describes and illustrates the construction of several 

 types of traps for use against house-flies, stable-flies, etc. Garbage 

 tins should preferably be fly-proof ; if they are not so, a balloon trap 

 is recommended for placing over a hole in the lid. Manure pits or 

 boxes for use in towns should be made of concrete or heavy planks. 

 The roof should be provided with one or more holes over which conical 

 traps can be fitted. Flies maturing in or attracted to the manure 

 thus pass upwards into the better illuminated trap. A modification 

 of the tent trap has been adapted for use in windows and is constructed 

 in such a way as to capture flies as they enter or leave the room ; this 

 type of trap has been found very useful in stables. 



Baits such as milk, beer, etc., are much more attractive to house-flies 

 when actively fermenting than when fresh. Home-made malt extract, 

 prepared by heating to 160° F. a mixture of 2 lb. ground malt and 

 1 U.S. gal. water was found to be as attractive as stale beer. Blow-flies 

 are attracted by the mucous membrane from the lining of the intestine 

 of pigs, either used alone or with beer. The latter combination is also 

 a valuable bait for house-flies. Bait containers should be large and 

 shallow, the diameter being not less than 4 inches smaller than the base 

 of the trap. For coating the surface of fly-papers for use in rooms a 

 mixture of 2 lb. resin and 1 pt. castor oil heated together is recom- 

 mended. Formaldehyde at the rate of two tablespoonfuls to a pint of 

 equal parts of milk and water is the best poison bait for house-flies. 

 Stale beer or molasses and water with 8 per cent, formaldehyde will 

 probably also give good results.

The examination of rats and mice was continued during the year. 

 Plague was not found in any of the specimens, thus leaving a plague- 

 free period since 1910. The following species of fleas were found on
