 " ^ . 3 mm. Apart from its larger size, this form differs from the 

 type by the more convex sides of the head, by the higher declivity of 

 the epinotum ; the latter is excavated above and behind to form a 

 longitudinal channel which is much mor*e distinct than in hcsperium 

 Em. The first node of the petiole is larger and higher than in the type 

 of Medinae, and more cuneiform. Its summit is almost linear (or 

 acutely angular). The legs are more slender. Very shining, except 

 the epinotum which is opaque and reticulate-punctate. Mesonotum 

 reticulate, slightly subopaque. Dark brown, the tarsi and antennae 

 paler, as in Medinae. Willowmore, Cape Pro v. (Brauns) ; host of

This ant is found on the south shores of the Mediterranean, India, 

 and Ceylon, and is represented in the Ethiopian Region by many sub- 

 species and varieties, which show a considerable range of variation, in 

 size, colour, and sculpture. 



For purposes of comparison, I reproduce the description of the type 

 form given in Andre's " Hymenoptcres d'Europe." 



" ^ . 2"5-3 - 5 mm. Head, thorax, and petiole brownish red, more or 

 less dark, very slightly shining or dull. The longitudinal sulcus 

 (excavation) of the clypeus superficial. Head slightly, abdomen 

 fairly, shining. Thorax deeply impressed between the meso- and the 

 epinotum. Mox*e or less castaneous brown, with the head blackish, 

 the abdomen brownish black. 



" $ . 6-7 mm. Dorsal profile of the thorax straight, from its front 

 margin to a little beyond the scutellum, without an angular break 

 between the latter and the mesonotum. Pilosity short and not very 

 close, but plainly visible ; pubescence scanty. Entirely blackish 

 brown, except the mandibles, the antennae, the tarsi, the thorax and 

 the petiole, which are entirely or partly somewhat reddish brown. 

 Head, thorax and petiole fairly strongly striate or rugose and dull. 

 Abdomen very finely coriaceous, moderately shining.
