rOEFICULA. 171 



This species was originally confused with CheUsoches pulcliellvs^ 

 Gerst., and reported as such in a paper on the Earwigs of Ceylon ; 

 some specimens were sent to de Bormans, who also identified 

 them as Gh. pulcliellus. That West-iVfricau species was then, 

 however, not properly known, and the name has since been shown 

 to be synonymous with Elaunon erytliroceplialns, Oliv. 



F. r/reeni, which is dedicated to Mr. E. E. Green, resembles 

 F. ornata, Borm. in build and colour, but differs in the less 

 pubescent body and more strongly dilated and abruptly attenuated 

 forceps of the male. It is easy to recognize by the dark colour 

 and the straw-coloured wings and spot on the elytra.

Size small, rather slender. Colour castaneous, elytra and wings 

 testaceous. Antennae with fourth segment comparatively long 

 and subconical. Head deep red, globose, smooth, sutures nearly 

 obsolete. Pronotum quadrate, anterior margin truncate, sides and 

 posterior margin very slightly convex ; dark castaneous, the sides 

 paler and flat, scarcely reflexed ; prozona slightly tumid, median 

 sulcus obsolete ; metazona flat. Elytra and wings ample, long, 

 smooth, testaceous. Legs short, clear testaceous. Abdomen 

 parallel-sided, dark reddish chestnut ; each segment darker basally 

 than apically : very finely punctulate. Last dorsal segment of 6 

 quadrate, rather sloping,"sHghtly wider than long, posterior margin 

 truncate, impressed in the middle and tumid on each side ; 

 typically angustate and simpler in the $ . Pygidium of d very 

 short, conical. Forceps of 6 \vith branches not very depressed, 

 dilated at the base for a short distance, this part crenulate then

This species resembles two other species which also occur in 

 Northern India ; one is F. planicoUis, Kirby, \\hich is smaller, 

 more thick-set, darker, with more bowed forceps, less flat pro- 

 notum, and more dilated abdomen ; the other is F. interrogans, in 

 which the forceps are much shorter and stouter, the dilated part 

 relatively longer, and the attenuated part straight, stouter and 

 shorter.
