82 Mr. M. Burr — Notes on the Forficularia. 



This is a very curious species. At first glance it might be 

 mistaken for Chelidura, but the simple second tarsal segment 

 at once shows that it belongs to a different group of ganera. 

 It might be provisionally ranged in Carcinophora, but, owing 

 to the very different form of the forceps, I have preferred to 

 erect a new and very distinct genus. 



Forjicula oriental™ , sp. n. (PI. IV. fig. 7.) 



Statura majore. F. auricularioe, atque F. luridce vicina, a quibus 



differt forma forcipis. $ ignota. 

 $ forcipis brachia basi valde deplanata et dilatata, hac parte mar- 



gine interno crenulato, tota inermia ; dehiuc valde divergentia, 



attenuata ad duas tertias partes longitudinis ; tunc subito re- 



curva, valde attenuata, apice fere attingentia. 



Long, corporis 15 mm. 



,, forcipis 4 „ 



„ ,, max 45 ,, 



Head reddish ; antennse testaceous, 12-segmentate, the 

 third segment small and round, the others elongate. 



Pronotum dark brown, the lateral margins clear testaceous. 



Elytra and wings fully developed, of the same form and 

 colour as in F. auricularia. 



Feet pale testaceous. 



Abdomen dark reddish, the lateral tubercles very distinct ; 

 the segments finely granulated. The last segment is square, 

 the posterior angles rectangular and depressed ; the hinder 

 border is straight, slightly tuberculated and broken ; in the 

 middleof the segment there are three faint depressions, arranged 

 in a line horizontally ; the abdomen is broadest about seg- 

 ments 5-6, and then slightly narrower towards the last 

 segment. The penultimate ventral segment nearly covers 

 the ultimate segment and is rounded. No pygidium visible. 

 Forceps : the branches are very strongly dilated in the 

 basal third, where the sides are at first parallel ; from the end 

 of the dilated part the branches diverge and are narrowed ; 

 in the apical third they are strongly arched inwards and 

 attenuated, the apices almost meeting ; the space thus en- 

 closed between the branches is a transverse oval ; the 

 branches are entirely unarmed, except that the inner margin 

 of the basal third, the dilated part, is faintly crenulated. The 

 colour of the forceps is black, except the centre of the dilated 

 part, which is testaceous. 



Patria. Constantinople (ex coll. Seeldrayers), 1 <$ and 

 1 nymph. 



Type in my collection.
