" Mas : prothorace trans versali^ tibiis anticis valde 

 arcuatis/^ 



" Femina: protliorace subquadrato, tibiis anticis fere 

 rectis." 



Oeratognathus alhoguttatus , Bates. 

 Ceratognaihus sexpustulatus, G. & H. Cat. Col. iii. 967. 



An elaborate description of G. alhoguttatus is given 

 by Mr. Bates (Ent. Mo. Mag. iv. 54)^ in which he truly 

 mentions it as one of the smallest species of the Lucanoid 

 Coleoptera, pointing out its affinity to C. helotoides, 

 Thomson. 



The second name, G. sexpustulatus, has erroneously 

 been recorded by Gemminger and von Harold as being 

 that of a distinct species; the error appears to have 

 arisen from the name sexpustulatus having been origin- 

 ally suggested, and afterwards changed by the author to 

 alhoguttatus. The habitat given in the '' Catalogus," 

 Moreton Bay, is also incorrect; the species was dis- 

 covered in the province of Canterbury, New Zealand, by 

 E.. W. Fereday, Esq., and at the period of its description 

 was, I believe, unique in Mr. Bates' collection ; a second 

 specimen from the same locality has recently been added 

 to my own. 



I now proceed to make some observations upon other 

 interesting species, notifying several which are new. For 

 convenience, a list of the novelties is prefixed. 



New Genera. 

 Pseudolucanus, Metadorcus, Pseudodorcus, Lissaptcrus.
