It will be observed that seventeen species have thus far been 
captured in Ohio. The most interesting among them, from an 
economic standpoint, are Anopheles maculipennis, which was 
taken at Sandusky, July Sth, 1003, and A. punctipennis, which 
has been taken at Columbus in March, July, September and 
October of various years, as they are the probable agents for the 
distribution of malaria. 
Aside from the biting propensities of many species of mos- 
quitoes, which cause annoyance and render some localities well 
nigh uninhabitable at certain seasons of the year, the knowledge 
that these two species are present in the state is very important. 
Although malaria is not considered a fatal disease, it caused 
sixty-eight deaths in the state during the year 1903, and doubt- 
less this number represents only a small percentage of the 
persons who suffered from its enervating effects. 
From the fact that one of the species listed, namely, Culex 
confinis, was first collected and described in South America, but 
was taken this summer at Sandusky, and further that the yellow 
fever mosquito (Stegomyia fasciata) was collected at Louisville, 
Ky., in October, 1903, by Dr. T. B. Berry, and has been found 
during the present year at Evansville, Ind., and Lexington, Ky., 
it is evident that some of the species of this family have a wide 
range of distribution 
It would appear possible for the latter sj^ecies to be carried 
by boats from southern ports to almost any Ohio river town. 
Our knowledge of the distribution of this and other species is at 
present imperfect, and many points concerning the habits, life 
history and hibernation must be investigated if the problem is 
to be dealt with in an intelligent manner. 
Neglect to obtain positive knowledge may at some future 
time result in loss of life, as well as seriously injure the business 
interest of localities involved ; hence it would appear that no time 
should be lost in carefully and thoroughly investigating the 
problem.
