some. In places where trees and scrub have been cleared to 
within 100 yards of the house and the draining of the surrounding 
land attended to, there is hardly a Mosquito to be felt day or 
night. 
The Anopheles generally make their appearance at night, but 
they appear to confine their attacks to the first part of the night. 
An exception to this is Anopheles lutzit, which lives in Bromelia 
water and bites during the day in shady places. In the woods pro- 
per the most troublesome species during the day are Psorophora, 
Fanthinosoma, Culex serratus, Culex confirmatus, Culex scholas- 
ticus, and several species of Wyeomvia. 
Educational Work. 
In connection with the Annual School Shows organized by 
the Education Department, specimens of injurious Insects are 
exhibited. In the past special attention has been paid to Mosqui- 
toes and these were exhibited alive in tanks with large labels 
attached. The following are exact copies of two of the series : 
Wrigglers or Mosquito Larve. 
CULEX FATIGANS. 
The night-biting Mosquito of Trinidad. 
Breeds in any foul water about houses and stables, is very com- 
mon in cesspits filled with water in the suburbs of Port of Spain 
and country towns. 
As this kind breeds in water, it can be exterminated by pouring 
kerosine oil on it.
