372 NOTES ON THE FAMILY BBACHYSCELIDiE. 



(J. Galls growing out from the side of the 9 gall just below the 

 apical orifice into a large mushroom-like mass, the outer side 

 covered with a wrinkled epidermis ; on the under side the tubular 

 male galls are all separated from each other, short, straight, 

 reddish-brown in colour, most of them toothed at the apex ; a 

 very fine specimen obtained from Newcastle district is 17 lines at 

 its greatest width and contains over three hundred male galls in 

 the one mass. 



Hah. — Newcastle, on E. sp. (R. Thornton). 



This remarkable gall was found in the Newcastle district by 

 Mr. R. Thornton, the well-known bush naturalist, to whom I am 

 indebted for a very fine collection of several species of Brachyscelid 

 galls. 



It is closely allied to B. pharetrata and B. nux, OllifF, but differs 

 considerably from both. The female galls often spring out in 

 clusters of five or six at the base of the leaves, and when immature 

 look like a bunch of finger-shaped excrescences.
