1 mention this insect in tliis connection, tliongli it does not directly cause 

 annoyance to man, because of the possibility that its presence may have 

 some bearing upon the spread of rindei'pest or other diseases of the 

 carabao. 



In conclusion it may be stated that conditions with regard to the 

 general prevalence of insects in Taytay do not differ essentially from those 

 in most of the inland towns which I have visited in the Philippines. The 

 life of the people is about the same as that in any other of a thousand 

 Filipino communities and, to my mind, what would be true of Taytay 

 with reference to hygienic and general sanitary or prophylactic measures 

 would apply to most other towns. 



At the end of this article a list is appended of the insects collected in 

 Taytay, so far as they have been determined, together with a statement 

 of their relative degree of prevalence. There is nothing new to report con- 

 cerning those which have pathologic importance.'' 



I am of the opinion that the type of midden pit used at Taytay offers 

 as serious a menace to health as the older plan of allowing pigs and 

 chickens to be the general municipal scavengers, because under present 

 conditions the flies which breed directly in the fasces and the mosquitoes 

 found breeding in these pits, which may become partially filled with 

 water, are certainly to be reckoned with as possible transmitters of typhoid 

 bacilli, ama?ba?, and filarias; while the chance of infestation with parasitic 

 worms. through the media of pigs and chickens seems much more remote. 

 Tf it were possible to have the midden pits nearly filled with water upon 

 the surface of wliich a few tablespoonfuls of petroleum or crude carbolic 

 acid wei'c poured weekly, then all danger of flies or mosquitoes breeding 

 in them would be removed; but at best this would be practicable only 

 in the rainy season and the work would require a better system of inspec- 

 tion tlum that furnished by the average municipal health officer.

1. Myzomyia rossii^ Giles, very common, taken in all streams where green 

 algae were growing; the undoubted transmitter of malaria in this town.

* Mysomyia rossii Giles has been previously noted by me and also by others 

 under the name M. ludlomi Theob., but during my stay in London last year I 

 proved to my satisfaction that the Philippine species is none other than M. rossii. 

 Professor Theobald told me that he had reached the same conclusion and that he 

 e.xpeeted to note it in his next volume on the Culicida;. I examined several 

 hundred specimens of 31. rossii in the British Museum and compared them with 

 an even larger number from the Philippines and could discover no essential 

 differences.
