Reddish-testaceous. Antennae yellow. Pronotum with the margins paler, and 

 with the posterior margin somewhat rounded. Elytra with the internal margins 

 rufous. Legs pale. Abdomen above and below with the disc rufous and the 

 margins paler, with all the segments somewhat rugose. Anal segment in both sexes 

 with a tubercle on each side over the inner side of the insertion of the legs of the 

 forceps, and in $ with two teeth in the posterior margin. Legs of the forceps in 

 both sexes slightly incurved and fuscous towards the apex, with minute denticulations 

 along the inner margin. The $ has a large tooth on the inner side of the forceps 

 beyond the middle of their length. Length, 19 — 30 mm. 



There are some half-dozen records of the capture of this fine 

 species, ranging from Bev. W. Bingley's original captures in 1808 to 

 that of the one in the possession of the late Mr. Kemp "Welch, which 

 was taken on the Dorset coast in 1886. The head quarters of the 

 species seems to be at Christchurch, Hants, where, in Bingley's time, 

 it appears to have been plentiful, and possibly it only wants looking 

 for to turn up in some numbers. It should be looked for about high 

 water mark in the evening. The other localities are Bournemouth, 

 Hengistbury Head, Bolkestone. 



ii.— ANISOLABIS, Fieb. 



This genus differs from Labidura in having no elytra or wings 



(as far as European species are concerned), in the lesser number 



(16 — 24) of joints in the antenna?, and in its unsymetrically curved 



forceps.

 Above dark pitchy, shining, below fulvous. Antennae 24 joints, fuscous. Pro- 

 notum nearly oblong, with a median longitudinal suture. No elytra and wings. 

 Third abdominal segment with a slight fold on the dorsal aspect. Last ventral 

 segments punctate. Legs of the forceps remote at the base in the $ , internal margin 

 denticulate, apices curved unsymetrically, the right more than the left. In <j> 

 symmetrical incurved and decussating at the apex. Length, 20 — 25 mm. 



This species has hitherto only occurred at South Shields, where it 

 was captured in some numbers by Mr. T. J. Bold in 1856, and he
