brown towards anal angle. Not a common insect, and, I be- 

 lieve, restricted to this colony. Flies in March. 



13. Cephalissa yacxaria, Gn. 



Expanse, V I". March and April. 



A variable insect as to ground colour, which is sometimes 

 dark-brown, sometimes tawny. There is always, however, a 

 nearly black bar, broad at costa and pinched in the centre, 

 running across the wing, and very much angulated on the out- 

 side. The hind-wings are grey. A common insect, flying over 

 grass. 



14. Cephalissa strtjmosata, Gn. 



Expanse, V 5". December and January. 



This is the largest and darkest of the genus yet found by 

 me. The ground colour, however, varies a good deal, being 

 sometimes very dark grey, and sometimes, especially in the 

 females, positively black, in which case the head, thorax, and 

 body are all of the same sombre hue. There is always a darker 

 broad bar crossing the wing, very much angulated on the out- 

 side, and distinguished from any other species known to me by 

 having two protuberances close together. Sits on palings and 

 trees — the dark ones on charred trunks, where, in spite of 

 their size, they are almost invisible, Bather a common species. 



15. Cephalissa subrectaria, Gn. 



Expanse, 10" to 1' 1". September and October. 



A dull-coloured insect frequenting damp places near creeks, 

 rivers, &c. It may be known at once by a straight, narrow, 

 silvery-white bar crossing the fore wings at three-fourths, and 

 another broader, but less distinct rounded one, at one-fourth 

 from base. Generally common. 



16. Cephalissa r^cr^ATA, Gn. 



Expanse, 10" to 1' 1". October and November. 



A very variable insect, both in markings and ground colour, 

 but nevertheless easily distinguishable. The ground colour 

 varies from yellowish-brown to purplish-red. There is always 

 a band crossing the wing, broad on costa, narrow on inner 

 margin, rounded on the interior, angulated on the exterior, 

 and a dark wedge-shaped spot at costal apex, which latter is 

 more hooked than in any other species of this genus. The 

 extreme outer edge of outer margin is distinctly white. A 

 very common insect in the hills. Elies over and among grass. 



17. Epyaxa subidabia, Gn. 

 Expanse, V 1". September and October. 

 This is also rather a variable insect, at first sight something 

 like C. vacuaria. The antenna? of male are, however, plumate
