THE EARWIGS OF CEYLON. 321 



few immediately preceding smooth, with a median line, slightly broader than 

 long, with a tubercular ridge at each side above the insertion of the forceps. 

 Penultimate ventral segment completely covering the last, except at the 

 angles, bluntly triangular, emarginate at the ap2x. 



The FOKCEPS, $, are stout, the branches, shghtly dilated on the inner 

 margin at the base with a blunt tooth-like tubercle above at the base, strong- 

 ly incurved almost immediately, the apices crossing ; the right branch is 

 much more strongly curved than the left, and crosses above it. Seen from 

 the sides the forceps are pointed somewhat strongly upwards. 



The 9 resembles the $ in size and colour ;-the abdomen also dilated and 

 then attenuated posteriorly ; the branches of the forceps are subcontiguous 

 stout, straight, curved upwards and decussating at the apex, the inner 

 margins denticulated. In the $ I can distinguish no signs of the lateral 

 abdominal tubercles. 



Hahitat—'S.^.iton, Ceylon, July, 1897 (0. 0. W.) 



This species approaches to A. maritima and A. mauritanica is the some- 

 what dilated abdomen and in the form of the male forceps. The absence 

 of a bifid pygidium, and the more strongly curved forceps distincruish it 

 from A. Tufescens, Kirb., which seems to be closely allied. It is a noticeable 

 species and not likely to be confused with others that occur in the island 

 The impressed line down the mesonotum gives it at first the appearance of 

 possessing rudimentary elytra, but as the line is a continuation of the line 

 on the pronotum, it can be seen that elytra are entirely wanting. 



ANISOLABIS ANNVLIPES, Luc. 

 Medium sized, black shining. Head black ; antennse with basal segment 

 reddish, the rest greyish-brown, except the two penultimate segments 

 which are whitish. Pronotum as broad as the head, sometimes paler in 

 colour, quadrate ; elytra entirely absent. Abdomen with sides more or less 

 parallel, with no tubercles upon the sides of the second and third seo-ments 

 Last dorsal segment larger than the others, slightly impressed in tbe middle. 

 Feet testaceous, the femora banded with black, as are also the tibi^ The 

 depth and intensity of this banding varies very considerably. Branches of 

 the forceps in the $ remote at the base, stout, strongly incurved the 

 right branch crossing above the left at the apex ; in the $ the branches are 

 straight, conical, subcontiguous. 



Length of body^ 11mm $ 12-14 mm. 



„ of forceps ^ 2mm $3-3*5mm.

 Anisolahis ammUpes, Borm. 190O, Forf. 48. (q. v. for synonymy.) 

 EaUtat.—Thi^ species is entirely cosmopolitan. From Ceylon I have 

 received specimen from Mr. Green from Punduloya and from Hatton, 



It is difficult to distinguish the various small species of Anisolalis, espe- 

 cially if only females and undeveloped specimens are to hand. A. annw
