 long, the scape extending beyond the top of the liead ; the 2nd 

 joint of Ihe flagellum longer than broad. Thorax short and 

 broad, thoracic sutures well-marked ; the pro-, nieso- and meta- 

 notum convex, the latter apically truncate and sloping; legs 

 robust. Node of the i)edicel comparatively erect and high ; abdo- 

 men broadly oval. 



2 . Resembles the ^ , but is dark brown ; the mandibles, 

 articulation of the joints of the legs, and the tarsi yellow ; the 

 antenna) very pale whitish yellow. Head square, posteriorly 

 slightly emarginate ; the mandibles and clypeus as in the ^ , the 

 antennae ])roportionately more slender and filiform, the basal two 

 joints of the flagellum of the antenna; (;longate. Thorax some- 

 what flat abov(! ; the wings hyaline, nervures pale yellow ; the 

 node of the pedicel and the abdomen as in B. myops.

 ocelli very large ; mandibles narrow and pointed ; clypeus ver\ 

 convex, transverse ; antennae filiform, the 2nd joint of the flagellum 

 elongate, longer than the 1st or 3rd. Thorax very massive ; the 

 mesouotum somewhat fiat ; the scutellum slightly convex, elevated 

 above the basal portion of the metanotum, which is horizontal and 

 shorter than the apical truncate portion.

Subfamily CAMPONOTIN^E. 



The species belonging to this subfamily are probably mentally 

 and socially the most highly developed of all the ants. Structurally 

 they are distinguished by having a one-jointed pedicel with no 

 constriction between the two basal abdominal segments ; the 

 poison-glands and sting are considerably modified, the former 

 bein<if converted into a cushion of convolutions, the latter forming 

 merely an orifice for the ejaculation of the poison, which in certain 

 genera (CEcojthtjlla, for instance) can be done with considerable 

 force ; the orifice of the cloiira is in this sahfamilii alivaijs circalitr, 

 and ciliated round the rnaryin. 



Cei'tain genera — Formica and Myrmecocystas — are well known 

 as slave-makers, but the habit seems confined to the species in 

 Europe, and does not, so far as has been observed, obtain in the 

 representative or even in the same species in India. Species of 

 the Camponotinct', and especially of the representative genus 

 Camponotm, are pre-eminently known as farmers of Aphides, 

 Honioptera, Lycacnid-larva?, and such-like ant-cattle. A most
