164 rOEFICULIDjE. 



United Peovinces : Mussoorie {Pusa coll.) • Madras : Banga- 

 lore (Ind. Mils.) ; Ceylon : Punduluoya and Ambegammoa (coll. 

 Burr); Madulsima, xii. {T. B. Fletcher; coll. Burr). 



Also in Annam (Paris Mus.). 



Type in the British Museum. 



This elegant species is easy to recognize by the clear yellow 

 colour of the organs of the anterior half of the body. It appears 

 to be common in India and Ceylon, though it was not taken by 

 Pea in Burma. Mr. Green commonly took it at light at Pundul- 

 uoya, and to one of his specimens attached a note, that it " when 

 handled, gave oiF a pungent odour like that of the Bombardier 

 Beetle." 



The mcicrolahia form, with very long forceps, appears to be more 

 numerous than the cyclolabia form. 



Genus FORFICULA, Linn. 

 Forficula, Linn. (1758) p. 423. 



Type, Forficula auAcularia, Linn. 



Body convex. Head smooth, tumid, sutures fairly distinct. 

 Antennae with from 10 to 15 segments ; third long, nearly as long 

 as the first, gently clubbed or cylindrical ; fourth generally shorter 

 than third, often much shorter; fifth a little longer than fourth ;. 

 the rest gradually lengthening ; all the segments almost or 

 entirely cylindrical. Pronotum more or less rectangular ; truncate 

 anteriorly ; posterior margin truncate or rounded, the hinder 

 angles rectangular or rounded. Elytra well developed ; smooth, 

 ample, with no keel. Wings prominent and abbreviated or 

 abortive. Legs moderately slender. Abdomen rather depressed, 

 broader about the middle ; gently narrowed apically in the 6 , 

 more strongly in the 5 > lateral tubercles distinct. Last dorsal 

 segment of d transverse, posterior margin smooth or tuberculate ; 

 in 2 simple, narrowed. Pygidium of c? small and globose or 

 strongly produced and prominent. Branches of forceps of cT always 

 depressed and always dilated in the basal portion, beyond which 

 attenuate and arcuate ; dilated basal portion short or long and 

 variously armed ; in $ simple, straight, contiguous. 



Eanr/e. This is a large and homogeneous genus, containing 

 about forty species distributed throughout Europe, Africa, and 

 Asia ; it is well represented in India, but it is not known to 

 occur in the Malay Archipelago. 



The dilation of the forceps near the base in the male is the 

 chief generic character, and the extent and armature of this dila- 

 tion offers valuable specific characters. The length of the forceps 

 varies remarkably, and the appearance of the macrolabia forms ^is 

 often very different from that of the cyclolabia forms.
