obtuse at its extremity.

Obs. — The above Pis. xanthopus may, perhaps, be a variety of 
this insect, in which case my name must fall, and Bridle’s be re- 
tained, although mine will be the species, and his the variety, as 
piceous, red, and even testaceous, are frequently the immature stages 
of black. The difference in the colour of the wings and nervures 
may also be accidental, as his is probably an insect in fine condi- 
tion, and mine are evidently old individuals ; and it is a fact long 
known, that the dark colour of wings, by exposure and wear, will 
become pale at the apex, and hyaline wings will frequently become 
fuscous. If, therefore, my suspicion be correct, which is founded 
entirely upon my male, the wings of his and the body of mine would 
constitute the true species. The several differences have induced 
me to describe mine as distinct, yet that of size is of no moment, 
as all these insects vary greatly in that particular. I am doubtful 
of its exact locality, but I believe it to be from the Cape.

Black ; the forehead, cheeks, entire thorax and base of the ab- 
domen, covered loosely with long grey hair. The emargination of 
the eyes, clypeus, cheeks, covered with silvery down. The mandi- 
bles bearded externally towards the base, and longitudinally cari- 
nated, the carina being formed by two furrows, their internal tooth 
placed at about one half their length, and very obsolete. Labrum 
transverse, slightly emarginate, and ciliated anteriorly. 
The carina of the central longitudinal furrow of the metathorax 
nearly obsolete, and the metathorax itself on each side irregularly 
and obliquely striated, the strife diverging from the base. The 
wings clouded-slaty, their extreme apex dark, and the nervures 
black ; tbe petiolated submarginal cell very minute, and receiving 
the two recurrent nervures at the inosculating points of its trans- 
verse cubitals. The tibiae and tarsi simple. 
The margins of the first, second, and third segments of the ab- 
domen depressed, and with its sides and the extreme edges of their 
margins reflecting an obscure silvery hue. ? .
