year in the traps. Psorophora were usually rare, but com- 
prised about 75% of a lot collected by hand or found dead on 
the window sills of the Agricultural Building. They were 
sometimes troublesome at night during May in Science Hall. 
Two or three specimens of Megarhinus were collected, but 
were never taken from traps. 
The percentage of females caught in traps is much lower for 
Culex than for Anopheles. Smith (1) has pointed out that 
male mosquitoes do not fly as far as females and that more 
females than males enter. the house. He collected some out- 
- side and some inside the house, a total of 1,350, representing 
several species. Of these taken outside, only a small per- 
centage (10-23%) of those breeding considerable distances 
away were males, while 60% of the Culex pipiens, which were 
breeding locally, were males. Of a total of 318 individuals 
taken within the house, Smith did not find a single male. 
Lefroy (2) caught an average of 21.8% females in a similar 
trap set inside the house. 
Culex were found breeding closer to both houses than 
Anopheles.

The number given as having blood in the abdomen included 
only those in which the blood was undigested and could be 
seen through the abdominal walls as a dark clot. All of those 
with the abdomen plump and distended, where no blood could 
be seen, were counted as having well developed ovaries, 
though some of them were probably distended with other food.
