Show 648 MR. A. D. MICHAEL ON THE [Dec. 1, irregular divisions, mostly scale-like in form and varying greatly 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 numbers found in the nests of Camponotus herculeanus (probably race ligniperdus and other varieties) near Innsbruck, Tyrol. L;ELAPS L/EVIS, n. sp. (Plate XLIX. figs. 3-3 b.) 2 millim.

Texture fully 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, slightly 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; pentreme 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. |
