from behind, is rounded and entire. Legs long and slender. Opaque; 
surface of body peculiarly shagreened so that it has a silky luster irre- 
spective of the pubescence. Mandibles very finely striated and with 
small, scattered, indistinct punctures. 
Hairs glistening white, short, blunt, erect, abundant, covering the 
whole body, except the antennae and flexor surfaces of the legs. Pu- 
bescence very dilute and delicate, more distinct on the gaster than on 
the head and thorax. 
Ferruginous brown; gaster dark brown; clypeus, cheeks, mandibles, 
tarsi, and articulations of legs paler, more yellowish red. 
FeMaLe. Length 9 mm. 
Similar to the worker in color and sculpture. Head somewhat 
broader than the thorax; clypeus feebly carinate, its anterior border 
more distinctly sinuate than in the worker. Thorax low, flat, with 
rounded epinotum. Superior border of petiole sharper than in the 
worker, but much blunter than in the female of fusca. 
Mate (?) Length 7-7.5 mm.; fore wing 5.5 mm. 
Black; opaque throughout; tips of mandibles and the genitalia 
red, the stipes of the latter partly brown. Pubescence on the gaster 
long, whitish, not very dense; erect hairs very short. Head short and 
broad. Mandibles opaque; anterior border of clypeus rounded. 
Thorax depressed. Petiole thick, cuneate, its upper border not ex- 
cised. Wings nearly colorless, with dark brown veins and stigma. 
Iberian Peninsula and Southern France (Eastern Pyrenees). 
The worker of this species is easily distinguished by its peculiar 
sculpture and, as Emery has pointed out, by the singular structure 
of the thorax in the mesoépinotal region. I have redescribed the 
worker from two specimens collected by Prof. G. Strobl at Algeciras 
in Andalusia. The descriptions of the female and supposed male are 
taken from Emery.
