202 ON THE SUB-FAMILY BRACHTSCELIN .f:, 



Brachyscblis dipsaciformis n.sp. 



. (Plate XIX., fig. 1.) 



9. Gall 6 lines high, 4| 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 jDunches 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. 



Hab. - 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.
