TEE EARWIGS OF CEYLON. 329 



18) ; the first three segments are pale, the rest black except the two penulti- 

 mate segments which are pale. The pronotum is straight in fronts 

 rounded behind, shining black, except the sides which are somewhat paler. 

 The scutellum is very small and difficult to distinguish. The elytra are 

 pBTtectly developed, shining brown, with more or less strongly developed 

 purple or blue metallic sheen, which is variable, and sometimes barely dis- 

 tinguishable. They are longer than the pronotum, truncated at the apex. 

 Wings absent. The feet are pale-testaceous, the femora strongly banded 

 with black. The abdomen is very slightly dilated, black, or blackish-brown, 

 occasionally even dark-red, bright-shining, clothed with a few bristles, the 

 folds of the second and third segments are absent or very faintly developed. 

 The abdomen is paler beneath ; the last segment is somewhat narrower 

 than the others, square. The forceps have the branches stout, almost 

 contiguous at the base, cultriform, finely denticulated on the inner margin, 

 nearly straight, but curved in towards the tip, the right branch more strong- 

 ly curved than the left. In the $ the branches are stout, contiguous, 

 decussating at the apex. 



Length of body $ 9 10-12 mm. 



„ of forceps $ $ 2-2-5 mm.

Habitat.— Ceylon (Kirb., Brit. Mus.) ; Galle, Ceylon (Dubr.) ; Ceylon 

 (Thwaites, in Mus. Hope, ex coll., Westw.) ; Kandy (Simon, in coll., Bolivar). 



C. castetsi, Bol., from Southern India is not very different in appearance ; 

 the branches of the forceps are more slender and strongly curved, and the 

 body is more dilated. 



This species does not appear to be rare in Ceylon, but I have received 

 no specimens from Mr. Green. In the Hope Collection at Oxford there are 

 nine specimens, from Westwood's Collection, captured by Thwaites. 

 Thanks to the kindness of Senor Bolivar, I have been able to examine two 

 females in his collection, determined by M. de Bormans as Carcinophora 

 cceruleipennis (Borm.). 



APTERYGIDA, Westw. 



Medium sized insects, or small. Antenna with 10-14 segments ; pronotum 

 narrower than the head. Elytra well developed; wings well developed or 

 abortive. Abdomen with lateral tubercles developed. Penultimate ventral 

 segment with semi-circular border, almost {$) or entirely (9) covering the 

 salt. Forceps $ with branches remote at the base, slender, incurved to 

 meet at the apex, with varying teeth on the inner margin. In the 9 con- 

 tiguous, slender, more or less flattened.
