NOTES ON THE SUB-FAMILY BRACHYSCELINJB WITH 
DESCRIPTIONS OF NEW SPECIES. — Part IV. 
By Walter W. Froggatt. 
(Plate xix.) 
Before describing several new species obtained during last year, 
I propose to rectify some errors in my previous papers on the 
gall-making coccids with, regard to their classification. 
In his last contribution to the study of the family Coccidce* 
Mr. Maskell, when dealing with the nomenclature of the sub- 
families, formed the sub-family Idiococcince for the reception of 
his genera Sphcerococcus, Cylindro coccus, and Frenchia. Many 
members of the above genera form regular galls, but others only 
waxy tests, while none of their galls are of the solid woody con- 
sistency of those of the Brachyscelid coccids; and the female 
coccids themselves differ structurally from the females of the latter. 
The Eucalyptus-gall coccids consisting of Schrader's three genera 
Brachyscelis, Opisthoscelis, and Ascelis coming into the sub-family 
Bracliyscelincb form another very natural group of the family 
CoccidcB. 
When re-describing Opisthoscelis subrotunda, Sch., in my earlier 
paper t, I stated that the larva had tarsi terminating in two 
claws, which, as Mr. Maskell has pointed out, would remove them 
from the Coccidce into the family Psyllidce; what I mistook for 
the second claw, I find upon more careful examination to be the 
lower digitule, appendages like fine spines springing from the 
extremity of the tarsi.
