point. One morning we found, on waking, that during 
the night a species of Anopheles had been feasting on us. 
These were noted because of their particular habit of pos- 
ure. It will be remembered that Anopheles is a carrier 
of malaria. 
Other Diptera under notice were crane flies pnd 
midges, both being attracted to light. The former are 
slender insects characterised by particularly long legs, 
hence the name. The midges are also very slender insects 
and usually very small. 
Some large robber flies were seen on the wing. These 
are predaceous in habit, possessing spear-like piercing 
mouth parts for stabbing their prey. They must not be 
confused with march flies, which have similar mouth parts, 
but usually suck blood from the higher warm-blooded 
animals, as was experienced. The robber flies never do 
this ; their food consists purely of other insects. 
Orthoptera . — Grasshoppers of various kinds were 
often disturbed from grass. 
A member of this order happened to be the most 
attractive and interesting find during the camp. It be- 
longs to the family Phasmatidae, whose, general name, 
under which they are very well known, is ‘ ‘ Stick Insects. ’ ’ 
The specimen was collected by a local resident who, know- 
ing of the Club’s camp, brought it to us. It is known 
scientifically as Extatosoma tiamtum , and affords a won- 
derful example in the study of protective adaptations in 
the insect class. It is a large insect 4 to 5 inches long, of 
rather stout build, green in colour, having the abdomen 
fringed with spiny processes, and the legs irregularly 
dilated, somewhat resembling leaves; in fact, the whole 
insect closely resembles a portion of a spiny-leaved plant. 
The females, to which the specimen secured belonged, 
have rudimentary wings. The males are smaller insects 
and are provided with ample wings. 
A few wood cockroaches were disturbed when bark 
was peeled from dead trees; a preying mantid was found 
amongst grass, while crickets were heard at night. 
Hemiptera. — Some plant bugs were secured by beating 
grass, but in general bugs were not common. 
Leaf-hoppers, interesting because of the sudden hop 
they make when disturbed, and an attractive little species 
of Psyllidae were common on Acacias. 
According to the noise produced, Cicadas were num- 
erous amongst the forest trees; some were observed flying 
about. 
Goleoptera. — Beetles were not abundant. A few small 
weevils were found by beating grass and tree foliage. 
Ground beetles occurred under logs and in leaf mould.
