ORDER HYMENOPTERA 
Melipona, sp. 
One or more species referable to this genus were seen in several 
places in the Congo Free State. They were particularly numerous at 
Leopoldville and Dibwe. They caused intense annoyance by the 
persistent manner in which they swarmed about one and crawled into 
one’s mouth, eyes, nose and ears. When crushed they emitted a 
peculiar and characteristic odour. 
At Leopoldville a colony of these stingless bees had taken up their 
quarters in a large lock and rendered it quite useless by the great 
accumulation of wax which they had formed. In this instance it was 
interesting to note a waxen tubular opening, about 4 cm. in length 
and about the thickness of a pencil, projecting from the keyhole. A 
species of Melipona has been noticed to have very similar habits in 
the Soudan.* 
INSECTS OF NON-ECONOMIC IMPORTANCE 
In addition to the insects dealt with in the foregoing chapters of 
this Report, a large number of insects, representative of various orders, 
were also collected; but as they are of no economic importance it has 
been thought desirable to deal with these elsewhere. We would add, 
however, that among the more remarkable species is a new Dejeania 
which was discovered among the Glossinac in the fly cages at 
Kasongo. It had evidently been caught by one of the boys in 
mistake for an engorged tsetse, which it very closely resembles. We 
also obtained several specimens of a rather remarkable species of
