inse&t par excellence with which newcomers to the = 
colony are especially familiar is the ubiquitous mos=- 
quito, which I think of all other inse& pests is the most _ 
annoying. The mosquito frequents low marshy land, 
the mouths of rivers which are at low tide expanses of 
mud, and mangrove swamps. In the far interior in the high 
lands, and well-drained tra&ts however, they are wanting. 
The eggs of the mosquito are generally laid in water, 
where they hatch and become swimming larve which 
remain there until the larval stage is complete when 
they attach themselves to grasses or water plants, turn 
into pupz, and afterwards crawl out of their cases as 
perfe€&t mosquitoes. The presence of fish in a tank or 
water with larvz is a remedy for mosquitoes, as the fish 
feed on the larve and prevent their reaching the per- 
fet stage. Many kinds of centipedes and millipedes 
can be found in British Guiana, but the commoner 
species of the former, Scolopendra angulata, is to be met 
with almost. everywhere; it is capable of infliéting a 
severe bite which causes swelling and great pain. Scor- 
pions are found in dry places where rubbish is put, under 
leaves and dead twigs, often too common in some 
places to be pleasant, and the colle&tor has to be careful 
when handling or meddling with them. In this colony 
they do not grow to anything like the size of the 
African Scorpion and can hardly be said to be as 
dangerous. By examining bushes and undergrowth one 
may often come across the Locust and the flying leaf 
Locust, the latter so named because it closely resembles 
a green leaf. 1 obtained a fine specimen of the latter at 
the Hobabo Benab, where it flew in towards the light. 
They are capable of jumping long distances, and have
