ON THE SUB-FAMILY BRA CHYSCELINJE, 
Brachyscblis Thorntoni, Froggt. 
In my description of this species in a previous paper* I have 
confounded two very distinct species, a collection of fresh material 
which I collected last year at Wallsend having convinced 
me of my mistake. The former description will stand for the 
female gall in an immature state (also figured in the plate), but 
that of the male gall mass as there described must be withdrawn. 
The male gall mass of this species is very variable in shape and 
size, often much curved and distorted, covered with warty 
excrescences and the edges broken and irregular, but the coccid 
tubes always coalesce and are not separated or distinct by them- 
selves. 
It is one of the most prolific species; I have seen some trees 
about Wallsend which are simply one mass of these galls; the 
more mature galls become more oval and lose the very pronounced 
ribs so conspicuous in the very young ones.

(Plate xix., fig. 3.) 
9. Gall 9 lines in length, not more than 1 J lines in diameter at 
the base, gradually swelling out to three lines at the apex; brown 
to pale red; rather wrinkled on the surface; walls of the cham- 
ber thin, the chamber tubular, extending from the base to the 
tip; apical orifice small, circular, apex of gall truncate; sometimes 
the gall stands straight out from the leaf, but more frequently 
hangs downward along it. 
<J. Gall forming a wrinkled irregular mass, growing from the 
side of the female gall close to the tip, swelling out into a rugose 
reddish brown mass, with the upper surface slightly concave, 
1^ inches across at the widest diameter and about a quarter
