346 NOTES ON THE FAMILY BRACHYSCELID^E, 



9. Coccid ochreous-yellow, shining and glassy, attached by the 

 whole of the underside to the floor of the chamber, almost oval ; 

 segmental divisions distinct, with an impressed spot on either 

 side of the first four segments ; the abdominal segments small, 

 tapering to the tail, fringed with scattered white hairs, the tip 

 truncate, the tail hidden ; tarsal joint of hind legs long and 

 slender, tapering slightly towards the tip. 



^. Galls reddish-biown to black, H lines high, broadest at the 

 base, tubular, tajjering towards the apex ; apical orifice irregular, 

 crenulated, the rim forming a number of irregular teeth ; growing 

 upon the leaves, and often in such numbers that the leaf is quite 

 aborted. 



The female galls are somewhat like a small variety of 0. 

 Maskelli at first sight, but the mature female (the only stage 

 obtained) is quite distinct, while the galls, which are very plenti- 

 ful in the Whipstick Scrub, do not vary in the slightest. 



Hah. — Bendigo, Vie, on E. leucoxylon and on E. gracilis in 

 August (Froggatt). 



Opisthoscelis serrata, n.sp. (PI. xvir. figs. 24-26). 



Q. Gall green tinged with yellow, spherical, 3 lines in diameter, 

 constricted at the base; formed upon the leaves, generally singly 

 but sometimes in groups of two or three ; basal orifice on under- 

 side of leaf an irregular slit with rugose warty edges : gall soft 

 and spongy, with the chamber large. 



9. Coccid pale yellow, elongate, rounded ; head rounded in 

 front and rising up in the middle between the eyes in a crescent ; 

 dorsal eyes globular, black, not on the edge but placed well in 

 the side of head ; outer margins of the thoracic and abdominal 

 segments on upper side serrate, with an irregular row of fleshy 

 teeth right round to the anal tip, the body swelling out under- 

 neath them so that they appear not to be the marginal edges 

 until closely examined ; abdominal segments lightly fringed with 

 hairs ; underside flattish. Antennae ferruginous, springing out of 

 the first fold, formed of four stout irregular cylindrical joints, the 

 last rounded at the tip and surrounded with scattered hairs; head
