But the female is a much stouter insect in proportion to her length than the worker, so that she must be nearly 5000 times as large. And this disproportion occurs not only among individuals of the same species but of the same sex and among the offspring of the same mother! The only other insects which exhibit a like disproportion are the workers and physogastric queens of the very termites with which

workers, probably remaining unnoticed on account of their small size, prey on the termites with impunity and are therefore able to rear such huge sexual forms. The larvae of these are so voluminous that they could not be moved by the workers and are so soft and vulnerable that they would have to be reared in chambers inaccessible to the termites. Although no detailed observations on the relations of the two species have been published, the subsequent accounts of observers in the field go to confirm Forel's inferences.

In the Katanga it lives in the mound-shaped nests of Acanthotermes spiniger. October 6, 1911, I witnessed at Sankisia a nuptial flight of this ant. It was at the very beginning of the rainy season and on the two preceding days it had rained abundantly. Toward noon numerous winged females were flying about everywhere in the savannah; they came from a certain number of termitaria, the sides of which were covered with fabulous numbers of the very small workers of the same species. I did not see copulation but, in the evening, I captured several males at light but no females. The following days the phenomenon was not repeated.</paragraph>

Several specimens of the female have been taken by me with one or more workers biting into the dorsal fimbriae. I am inclined to suspect that the young queen cannot start a new nest without the help of one or more of the workers from the old nest, on account of the size of her mouth-parts, which would probably be too large and clumsy to tend the tiny larvae of her first brood, and that it is therefore essential that she should have with her some workers which are able to feed the larvae by conveying to them the nourishment from the mouth of the queen.</paragraph>
