unlikely that if it be a female the male differs materially except 

 in probably having a longer antennal club. I have not been 

 able to make a proper examination of the front margin of the 

 mentum (which is rugulose and clothed with extremely long setae, 

 and therefore difficult to study without dissection).

The species for which I propose the above generic name must 

 certainly I think stand near the preceding one (Anacanthopus 

 inermis) on account of the close resemblance between them in 

 respect of the oral organs (the narrow rough mentum clothed 

 with very long sparse setae, the very long apical joint of the 

 maxillary palpi, <fec.), and a decided agreement in facies. The 

 present insect however has a less marked resemblance to a 

 Dynastid and differs from the preceding in several important 

 structural characters. It is distinguished from all the other Aus- 

 tralian Sericoides so far as my observation goes by its very large 

 eyes, the interval between which is so narrow that the middle 

 part of the head (limited in front by the clypeal suture, on the 

 sides by the eyes, and behind by a line joining the hind extrem- 

 ities of the eyes) is scarcely if at all wider than long.
