Orbicular, convex, black, shining ; the forehead flat, ob- 

 scurely punctulate, Avith the stria well-marked and passing 

 laterally along the epistoma, which is not depressed like that 

 of E. Lucasij Mars. ; the thorax convex on the disk, depressed 

 at the sides, very finely punctulate ; the elytra, strias short, 

 basal, nearly obsolete, punctulate, except on the disk ; the 

 propygidium and pygidium finely and evenly punctulate ; 

 the prosternum, strias and the surface between tliera some- 

 what built up from the sides, with the keel or space between 

 the strias a little convex, the strias are sinuous between the 

 coxEe and the punctuation of the keel is stronger than that of 

 E. cirtensts, Lew. (see Ann. & Mag. Nat. Hist., Sept. 1892, 

 pi. xix. fig. 3) ; the last-named species, moreover, has a flat 

 keel, with the adjacent lateral parts on a level with it. 



Above this species is extremely like E. Lucasi, Mars., but 

 beneath the prosternum corresponds more with E. kabylice 

 and cirtensis. 



Hah. Bougie. I found a single example on the 30th April 

 last in a nest of Aphanogaster testaceoptlosa.

This species and S. punctulatus, Lucas, are peculiar in 

 having the tibial grooves for the reception of the tarsi
