Meyrick. — Revision of New Zealand Notodontina. 251 



me twenty-six years ago in Pror. Linn. Soc. N.S.W. 1890, p. 876). If we 

 are ever able to regard these as conspecific, onr notions of species will 

 have undergone remarkable change. 



As in previous papers of this series, I have only given synonymy and 

 references sufficient for local use. 



1. HYDRIOMENIDAK. 



Forewings : 10 rising separate, anastomosing with 1 1 and 9 (forming 

 double areole), or rising out of 11 and anastomosing with 9 (forming simple 

 areole). Hindwings : 5 fully developed, parallel to 4, 6 and 7 almost 

 always stalked or connate, 8 anastomosing with upper margin of cell from 

 near base to beyond middle, or seldom approximated only and connected 

 by bar beyond middle. 



A very large family of universal distribution, equally plentiful in New 

 Zealand. 



1. Tatosoma Bu'tl. 



Tatosoma Butl., Cat. Lep. N.Z. 17 (1874) ; type, agrionata Walk. 



Face smooth. Antennae gradually dilated from base to near apex, 

 apex attenuated in o simple. Abdomen in $ extremely long. Fore- 

 wings: areole double. Hindwings small, in o with dorsal lobe folded into 

 a pocket, 8 free, connected with cell by bar before angle, in $ neuration 

 normal. 



Endemic ; it is, however, a closely related development of the character- 

 istically South American genus Rhopalodes, from which it differs only by 

 the unusual elongation of the male abdomen. The habits of these curious 

 insects should be an interesting study.
