A memoir was also read by Mr. Westwood, " On the Australian 

 genus Cryptodus, and upon Parastasia, the Asiatic representative of 

 the Rutelida." m 



After noticing the singular character of the genus Cryptodus, and 

 its location by Mr. MacLeay, at first in the family Trogida, and lat- 

 terly, in Dr. Smith's African Researches, as one of the primary forms 

 of the Cetoniida, including Cremastocheilus, Genuchus, &c. as its sub- 

 genera, the author institutes a comparative examination of its struc- 

 ture in detail with the last-named groups, as well as with the Tro- 

 gida, and also with the Phileurideous Dynastida, which last are re- 

 garded by him as the true affinities of Cryptodus. The nine-jointed 

 antennae, upon which so much stress has been laid by Mr. MacLeay, 

 is proved to be only a specific character, Mr. Westwood describing 

 a new species with the following characters. 



Cryptodus Tasmannianus, W. Niger, nitidus, oblongus, punctatus, 

 antennis 10-articulatis, mento basi recte truncato , prosterno an- 

 tice producto , mar gine antico fere recto. Long. corp. lin. 9^.
