 clear-yellow. The general colour of the upper surface varies from brown- 

 ish-black to raddish-brown. Length of the body 15-18 mm., of the forceps 

 9-12 mm, ^, 



Habitat. — Eastern India ; Tranquebar (Dohrn) ; Madras (Mus, Hope) ; 

 Ceylon (Dohrn), 



I have never seen specimens of the fine earwig from Ceylon, It should be 

 sought for under stones in damp places.

Size small. Body flattened, slender ; antennae with 10-15 segments, the 

 segments conical ; elytra well developed ; wings usually well developed. First 

 and third tarsal segments equal, the second very small, simple. Second and 

 third abdominal segments with lateral tubercles ; forceps usually short, 

 slender, the branches remote at the base in the male, arcuate, horizontal, 

 simple in the female, straight and crossing. at the apex.

This genus may be generally recognised by its small size, A universally 

 distributed and closely allied genus is Spongophora, Serv., they may be 

 separated as follows. 



Labia. — Antennas with 10-15 segments, which are short, distinctly conical, 

 that is to say, considerably larger at the apex than at the base. The first 

 tarsal segment is slightly longer than the third, or equal to it ; the second 

 cylindrical and very short. Penultimate ventral segment ^ rounded, 

 Spongophora. Antenna with at least 15 segments,- these, except the fourth, 

 short and conical, nearly cylindrical ; first tarsal segment considerably longer 

 than the third ; the second cylindrical but slightly longer than in Lahia. 

 Penultimate ventral segment $ nearly rectangular (after de Bormans), 

 LABIA MUCRONATA, Stal. 



Very small. General colour dark-brown. Head shining black. Antenna; 

 yellowish, darker towards the apex, with 14 segments, Pronotum quadrate, 

 narrower than the head, black, the sides paler, the angles rounded, slightly 

 broader posteriorly than anteriorly. Elytra long, dark-brown, with a broad 

 testaceous stripe on the outer margin from the shoulder to the apex. Wings 

 varying in length, but projecting beyond the elytra, testaceous, with c broad 

 dark stripe on the suture. Femora black, testaceous at the apex; tibix 

 testaceous, black at the base; tarsi testaceous. Abdomen more or less dilated, 

 shining black, or dark-brown ; the last segment considerably narrowed. In the 

 $ the pygidium is short, stout, triangular, obtuse, in the $ it is not noticeable.
