THE VICTORIAN NATURALIST. 81 



A CATALOGUE OF VICTORIAN HETEROCERA. 

 By Oswald B. Lower, F.E.S. 



Part V. 

 Group— GEOMETRINA. 



The usual method employed in arranging the Heterocera is to 

 place the Noctuina next to the Bombycina, but Meyrick (Tr. Ent. 

 Soc, 1892, p. 53 et seq.) has shown — and I agree — that the group 

 under notice is closely related to the last-named group, especially 

 the Notodontidce; and when one considers the Bombyciform build 

 of some forms of Monocteniadce the truth of the statement cannot 

 be doubted. Meyrick's observations have not been formed in 

 any hurried manner — I find on investigation that he dissected and 

 examined over 2,000 specimens — and, considering the status he 

 holds in the entomological world, his opinions should be treated 

 with the greatest respect. My own opinion is that it is quite 

 feasible to show the transitional links in any group, but when 

 applied to the whole becomes impracticable. For instance, it 

 requires a stretch of imagination to fill in the gap between the 

 Saturnidce and Strophidiadce. The Pyralidina, which Meyrick 

 considers of Bombycoid ancestry, seems to connect or follow the 

 Noctuina better than any form of Geometrina, especially the group 

 called by Guenee Deltoidce, species of which at first sight re- 

 semble them greatly. I may here mention that the majority 

 of the species herein mentioned are described clearly by Meyrick 

 in Linnean Society's Proceedings of New South Wales, from 1878 

 to date.
