210 NOTES ON THE FAMILY BRACIIYSCELID.E, 



what portion of the coccid the latter is produced), to be well- 

 defined tails. 



In this paper I have redescribed Schrader's species, of which he 

 gave very meagre details ; and I have added two new species to 

 the genus Ascelis. 



Opisthoscelis subrotunda, Schrader, Trans. Ent. Soc. N.S.W. 

 1862, Vol. i. p. 7, pi. III. figs. 1-0. 



9. Gall 5 lines in diameter, round, dull green to j^ellow, growing 

 upon leaves ; a small circular basal orifice in the centre of the 

 brown button-like patch on the underside of the leaf; gall chamber 

 small, closely enclosing the coccid, the walls thick, showing a 

 radiating structure when cut across. 



5. Larv?e pale red, with semitransparent legs and antennae ; 

 enclosed in an oval white egg-sac, on emerging from which they 

 are very active ; antennae stout at base, composed of 4 (X) short 

 joints surmounted by a bristle as long as the combined joints ; 

 slightly lobed in centre of head ; body short, shield-shaped, rather 

 pointed at the apex, with a distinct marginal rim, forming a 

 fine serrate edge extending right round from the head to the tip 

 of abdomen, a little more oval than round, abdominal segments 

 narrow but distinct ; legs stout, long, tarsi terminating in two 

 finely hooked claws ; anal segment with a long slender filament 

 half the length of the whole insect, produced on either side. 



9. Coccid (1st stage) reddish-yellow, almost oval but slightly 

 constricted towards the tip of the abdomen, closely covered with 

 fine downy hairs forming a fringe round the margin ; dorsal eyes 

 small, round, black, and shining; the centre of the ventral surface 

 of the second segment or fold with a pear-shaped orifice, which in 

 live specimens under the microscope shows a regular throbbing 

 movement ; on either side of the mouth a short pointed thiee- 

 jointed leg ; the 2nd thoracic segment with a similar pair of legs 

 slightly longer ; the 3rd thoracic segment with longer stouter 

 legs, with elongated tibi?e. 



9. Coccid 4 lines long, 3-| broad ; reddish-brown, covered with 

 close fine hairs ; dorsal surface rounded, broadest at the top, 

 tapering to the anal tip, segmental divisions distinct ; ventral
