648 MR. A. D. MICHAEL ON THE [DeC. 1, 



irregular divisions, mostly scale-like in form and varying greatly in 

 size, every division has a crinkled edge. Legs in both sexes without 

 apophyses or projections, first pair considerably the thinnest, all legs 

 terminated by claws and long-shaped caruncles with five anterior 

 points (fig. 2 e) ; on the front pair of legs the claws and caruncles 

 are attached to the end of a rod-like projection of the tarsal joint 

 (fig. 2 d). This is common in the Gamasince, but is much developed 

 in this species. 



Hab. Considerable mimbers found in the nests oF Gamponotus 

 herculeanus (probably race ligniperdus and other varieties) near 

 Innsbruck, Tyrol.

Colour lightish chestnut. 



Textw'e i\\[\y chitinized, highly polished, entirely without markings. 



Shape a long ellipse, almost parallel-sided ; slightly rounder 

 posteriorly than anteriorly ; much arched on the dorsal surface. 



Mandibles of male (fig. 3 a). — The fixed arm of the chela has 

 a bifid or bidentate termination, but is not otherwise dentate. 

 Movable arm only slightly recurved at the distal end, and with a 

 single small tooth in addition to the terminal point ; it also has a 

 long, slender, shghtly curved, and undulated tri- or quadri-dentate 

 accessory piece, with a singular slightly knobbed end with a spike 

 directed backward ; it projects considerably beyond the principal 

 portion of the chela. Epistome (fig. 3 b) hyaline, indented at a very 

 obtuse angle at each side, and projecting in an obtuse angle, almost 

 a curve, in the centre, the whole edge serrated, the serrations 

 strongest just behind the points of the side angles. There are a 

 few extremely minute white hairs on the dorsal surface, so small as 

 to make it quite impossible to depict them in a drawing on the scale 

 of fig. 3. 



Underside of female with anal plate small, spade-shaped ; genital 

 and ventral plates fused, the former with a rounded anterior edge, 

 not quite touching the sternal plate. Ventral plate not quite 

 touching the anal. Stigma between the third and fourth legs ; 

 peritreme slightly undulated. Legs in both sexes without apophyses. 

 All legs terminated by claws and long-shaped caruncles. 



I am not able to give the measurements of the male. I only 

 found one specimen, which I unfortunately dissected before I found 

 out that it was the only example. 



Hab. A few found in the nests of ground-ants (species not known) 

 near Innsbruck, Tyrol.
