and at the base of the prothorax where some cilise project hind- 

 ward ; the legs and sterna are moderately hirsute. Having only 

 a single specimen I have not been able to dissect, but as far as I 

 can see the mouth organs are similar to those of Lepidiota. The 

 3rd joint of the antennse is evidently shorter than the 4th ; the 

 clypeus is almost evenly rounded (scarcely sinuate) in front ; the 

 prothorax is not bisinuate at the base ; and the ventral sutures. 

 are so much obliterated that the basal four ventral segments 

 (except quite at the sides) have quite the appearance of being only 

 one large segment ; the hind tibiae have two fairly well-defined 

 oblique carin^e. I cannot form a decided opinion as to the sex of 

 the specimen before me. The flabellum of the antennae is not 

 quite so long as the preceding five joints together, but the shape 

 of the pygidium resembles that of the male of Lepidiota. In res- 

 pect of all the characters not mentioned above I can find no dif- 

 ference from Lepidiota. The shape of the elytra (considerably 

 dilated hindward) and their freedom from scales cause a general 

 appearance suggestive of Colpochila, from which genus the 

 strongly dentate claws, obliterated ventral sutures, and many 

 other characters depart widely.

 The free margin of the clypeus is strongly reflexed. The pro- 

 thorax is nearly twice as wide as long, the base being two-thirds 

 again as wide as the front, and the sides being abruptly (and 

 roundly) dilated just behind the middle as in Lepidiota; the hind 

 angles are obtuse but quite Avell defined ; both base and front are 

 distinctly margined. The anterior tibiae are tridentate externally, 

 all the teeth being well defined, but not very sharp. The 

 pygidium is not quite half again as wide as long, and is sub- 

 vertical.

 believe it to be in S. Australia.
