The Coachella Valley (California) borders upon Salton Sea, it lies on an average of about 125 feet below sea level and has a population of about seven thousand inhabitants among whom are many Mexicans and many transient negroes during the cotton picking season. During the past ten or more years Hippelates flies (Hippelates fiavipes) have become increasingly numerous, until now they are a veritable pest and together with numerous cases of so-called "pink eye" affecting the people of the valley and the known relation of this fly to the disease, there exists a really serious situation. The breeding habits of the fly remain unknown as yet.

The black widow spider, Latrodectes mactans, occurs in the Valley in considerable numbers and several serious cases of spider bite have been reported with one fatality. The German cockroach (Blatella germanica) is increasing enormously in this region and is rapidly becoming a real pest.
