object, where it rests for a short time, and then resumes the 

 upright attitude. A large species, attached to seaweed. 



Vorticella zealandica. 



Body attenuate, from two to three times as long as the 

 greatest breadth, tapering downwards, considerably constricted 

 below the peristome, then swelling for rather more than half 

 the length, when it again becomes constricted ; then a nearly 

 circular swelling, giving the posterior end an unusually blunt 

 appearance. 



Apparently striated perpendicularly ; but of this I am not 

 certain, as at some times the striations were seen, while at 

 others they disappeared, as though at the will of the animal. 

 Pedicle slight, four times the length of the body. Length of 

 body -^Ijy inch.

 KlEBY, F.E.S. 



In order to avoid the premature multiplication of genera I 

 employ Epitola in the extended sense in which it was used 

 by the late Mr. Hewitson ; but it must not be forgotten that 

 there are three very distinct forms in the genus : — (1) Epitola 

 elion, Doubl. &Hew, (the type), a large insect, with the hind 

 margin of the fore wings strongly emarginate ; (2) E. cerau- 

 nia^ Hew., a smaller insect, with rather long fore wings and 

 the hind margin oblique and less strongly emarginate ; and 

 (3) the comparatively small species with rounded wings which 

 form the bulk of the genus as it stands at present. I believe 

 the last are sometimes arranged under Phytala^ with the type 

 of which they have also but little resemblance. 



Epitola urania. 



Expands 2\ inches. 



Male. — Fore wings : costa strongly arched, tip rounded 

 and produced, the hind margin deeply concave and then 

 rounded to the inner margin. Hind wings rounded, more 

 obtusely towards the inner margin. 



Wings rich blue, shading into purple towards the edges ;
