ON THE SUB-FAMILY BRACHYSGELINjE, 
Brachyscelis dipsaciformis n.sp. 
(Plate xix., fig. 1.) 
Q. Gall 6 lines high, 4 J in diameter, generally oval but 
sometimes rounded at base, black to dark reddish brown in colour; 
produced upon the twigs of a slender-leaved eucalypt, sometimes 
solitary but chiefly in bunches of two or three; they grow out at 
the base like a small button, with the spines forming an erect mass 
on the upper surface, but as the gall matures it gradually forms a 
round solid centre with these spines turning downwards into a 
regular prickly covering, which reminds one of a small teasle. 
The walls of the galls are thin and solid; the chamber oval; the 
apical orifice small and circular, with the spines surrounding it 
often broken away or aborted into little woody bracts. 
9. Coccid dull yellow, short and stout, very hairy; the legs 
short with very small tarsal claws; dorsal side, the abdominal 
segments each bearing a row of very long slender spines, and 
thickly fringed with long hairs, increasing in density towards the 
tip where they form a regular brush; the anal appendages black, 
short, stout, and cylindrical, with a distinct median division and V- 
shaped cleft at the tips, which are slightly pointed. Upon the 
ventral side the hairs are of a pale golden yellow and much longer 
than the anal appendages. The coccid here described was dead 
and partially dried up when taken out of the gall. 
Gall and coccid unknown. 
Bab. - North Queensland (Mr. F. M. Bailey). 
I am indebted to my friend Mr. J. G. O. Tepper, of the Adelaide 
Museum, for the opportunity of describing this curious little gall, 
which he informs me was forwarded to him from Brisbane by the 
Government Botanist (Mr. F. M. Bailey), with the information 
that it came from North Queensland.
