p 2. Formica fuliginosa is only Brit. Species in which little or no difference of size can be detected amongst the workers.— In many foreign genera there is no such difference. But in the Attidæ (p. 161) such difference is characteristic of the family.

p 3. Formica rufa. has twice found Colonies on Myrmica lævinodis & of other species" living in perfect harmony with the rightful owners in the very heart of the nest.— Anomma is the driver ant.

Mr Bates says the medium sized workers were occupied in cutting leaves, where there were few of the minute workers, which latter were in vast numbers in the dome of the nest. The very gigantic large headed workers were seen only when the nest was disturbed. In the main burrow there were vast numbers of the minute workers unmixed with any of a larger size. Mr B. says there are workers intermediate between the largest & next size. Mr Smith says the smaller workers sent home differ from 2/10 to 5/10 in size, whilst the largest workers scarcely differ amongst themselves in size; these latter alone have an ocellus. —
