Lahiduridae, a family of the Dermaptera. 175 
9. Gonolahis verhoeffi.,* Burr. 
Gonokibis verhoeffi, Burr (1905^), p. 487. 
This species is well marked by the prominent teeth on 
the upper surface of the forceps of the male, near the base. 
In addition to the two males in the Hope Museum, 
Oxford, I have received a third from Kuranda, Queensland, 
sent me by Mr. Simmonds. 
Genus 3.—Anisolabis, Fieber. 
This genus contains about forty species, even after the 
separation of those furnished with rudimentary elytra into 
the genus Enhorellia. It requires a thorough revision, as 
a good many names will require to be sunk in synonymy, 
and perhaps one or more new genera may be necessary. 
For instance, the gigantic Anisolabis colossea, Dohrn, from 
New South Wales, may be conveniently separated owing 
to its produced and apically rounded metasternal lobe. 
I will not, however, offer a revision yet, as the material is 
not complete. 
Immature specimens of Psalis are frequently mistaken 
for some of the less well-marked species of Anisolabis. 
Some of the smaller kinds seem to pass insensibly from 
one form to another, with subtle distinctions that are 
difficult to express. My personal inclination is to sink all 
species which are not clearly defined upon some well- 
marked structural character, though it is not always easy 
to say which forms should be fused. In this respect, as 
in the analogous case of Labidura riparia, I assume the 
attitude of a frank “lumper.” j- 
The genus Anisolabis has become less unwieldy now 
* Since writing the above, I have identified this species with 
Anisolabis brunneri, Dohrn, of which I have seen the type. A. 
bnmneri of Burr is a totally different creature. 
f Since going to the press, further material has been examined, 
which will be dealt with in a later paper. But it may be mentioned 
here, with reference to the above table, that A. incerta, Borm., 
appears to be a melanic form of /estae, Borelli; that vl. etero- 
nonm, Borelli, is in my opinion indistinguishable from A. anmdipes, 
Luc., as also A. aporonoma, Borelli. 
The species referred toby me as A. brunneri, Dohrn, and recorded 
and figured by me in (1908*9) P- I* hg- 
brunneri of Dohrn, which is the same as Gonolahis verhoeffi, Burr ; 
the A. brunneri figured by me is a well-known species which requires 
a new name, unless it can be identified with A. pacijica, Erichson.
