.308 FOBMICID.*;. 



subtriangular, anteriorly lightly arcbed; antennae thick and rather 

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

 joint of the flagellum longer than broad. Thorax short and 

 broad, thoracic sutures well-marked ; the pro-, meso- and ineta- 

 notum convex, the latter apically truncate and sloping; legs 

 robust. Node of the pedicel comparatively erect and high ; abdo- 

 men broadly oval. 



$ . Kesembles the , but is dark brown ; the mandibles, 

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

 antennae very pale whitish yellow. Head square, posteriorly 

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

 antennae proportionately more slender and filiform, the basal two 

 joints of the flagellum of the antennae elongate. Thorax some- 

 what flat above ; the wings hyaline, nervures pale yellow ; the 

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



d . Eesembles the $ in colour. Head orbicular ; eyes and 

 ocelli very large ; mandibles narrow and pointed ; clypeus very 

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

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

 mesonotum somewhat flat ; the scutellum slightly convex, elevated 

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

 shorter than the apical truncate portion. 



Length, $ 2*3-2-3 ; $ 3-5 ; <5 2-2-5 mm. 



Hal. Eecorded from the North-West Provinces (Smythies), 

 Western India (Wroughton), and Ceylon (Yerbury). Probably 

 spread throughout our limits. 



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 

 being converted into a cushion of convolutions, the latter forming 

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

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

 force ; the orifice of the cloaca is in this subfamily always circular, 

 and ciliated round the margin. 



Certain genera Formica and Mynnecocystus 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 Camponotince, and especially of the representative genus 

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

 Homoptera, Lycae aid-larvae, and such-like ant-cattle. A most
