8 MANDIBULATA. DERMAPTERA. 



Sp. 1. minor. Pubeseens, testacea, capite nigricante, ore pallida, thorace fusees- 

 cente, elytris pallidis, an tennis Juscis apice albidis. (Long. corp. 3 — 4 lin.) 



Fo. minor. Linne. — La. minor. Samouelle, pi. 4i. f. 16. — Steph. Catal. i. 299. 

 No. 3303. 



Pubescent ; head dusky, rather pale ; eyes black ; thorax rather fuscescent, 

 finely punctured ; elytra very pale, and also very finely punctulated ; 

 abdomen reddish, black in the middle, the terminal segment in the male 

 with a ridge, and armed with slightly incurved forceps, which are furnished 

 within with numerous equal denticulations : in the female they are straight 

 and scarcely denticulated ; legs pale yellowish. 

 Very abundant in the spring, throughout the metropolitan district, 



flying about in gardens and near stables, &c., especially in the 



vicinity of dung-heaps. " Berwick-on-Tweed." — C. C. Babingtoti,

Genus IV.— LABIDURA, Leach. 



Antennae rather long and slender, with about twenty-five joints, the basal one 

 stoutish, second minute, third rather longer than the fourth and fifth (which 

 are scarcely longer than the second) united, the five or six following also 

 short and stoutish, but gradually increasing in length and decreasing in 

 breadth ; the remainder are slender and elongate, and not very distinctly 

 separated, each articulation being about equal in length to the third. Palpi 

 rather long, terminal joint somewhat rounded at the apex ; head elongate, 

 triangular, wider than the thorax, the latter truncate, and with acute angles 

 in front, rounded behind, the disc much depressed ; body glabrous ; abdomen, 

 in the males, with the caudal appendage remote at the origin, slightly 

 curved upwards and approximating at the apex, denticulated behind the 

 middle within ; in the females approximating at the base, denticulated 

 within from thence nearly to the apex, the tips decussating ; tarsi pubescent 

 beneath, with the intermediate joint simple. 

 Exclusively of the form of the forceps, which are remote at their 



origin, and of the intermediate joints of the tarsi, the numerous 



abbreviated articulations of the antennae remove this genus from 



Forficula, as the last character does from Labia.
