upon the Genus Scaphura, ^c* '-29 



Notwithstanding the opinion of so high an authority as Mr. Kirby, 

 with reference to the osculant situation of this group, between the Grass- 

 hoppers with long antennse and the Locusts, I am induced to consider 

 that it possesses very little relationship with the latter. Its general habits 

 and the formation of the tarsi approach the former, but the long antennae, 

 the formation of the anterior tibiae, and the anal fillets present affinities 

 with the Crickets. It differs, however, from both these groups in the 

 absence of the talc-like spot at the base of the tegmina of the males, in 

 which respect (alone) it agrees with the Locusts. 



Vigor sii. Sp. 1.

A specimen (?) of this insect is now before me, from the cabinet of my 

 friend, T. W. Edwards, Esq., F.L.S., &c., which exhibits the following 

 appearances : — The four posterior femora are adorned, near the centre, 

 with a triangular spot, not extending in the intermediate pair either to 

 their under or inner surface, nor in the posterior (in which the spot is 

 much larger) to the under surface of the femora. The tegmina are red- 

 brown, dark at the base, and gradually growing paler to the tips ;* trans- 

 versely marked on the anterior margin with several short diagonal pale 

 lines. In the coloured figure the palpi of the insect are introduced, but 

 with somewhat the appearance of forming two triangular white lateral 

 lobes to the prothorax, more especially since that part is described as tri- 

 lobed, the word postice introduced into the generic character of the pro- 

 thorax before the word trilohus, would, however, explain the formation. 



Mr. Kirby describes his specimen as being 14 lines long, Mr. Edwards' 

 is 1 1 long, and the expansion of the tegmina is 1 inch and 1 1 lines. 



The following specific character may be inserted, the better to distin- 

 guish this species from the two following. 



Sc. atra, abdomine coerulescenti, femoribus 4 posticis macula media 

 albida, tegminibus fusco rufis, apice pallescentibus, alis fuscis. 



* In the figure the tips are incorrectly coloured darker than any other part 

 of the tegmina, which induced me at first to consider Mr. Edwards' specimen 

 as distinct.
