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

 genus Cryptodus, and upon Parastasia, the Asiatic representative of 

 the Rutelidce." 



After noticing the singular character of the genus Cryptodus, and 

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

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

 of the Cetoniidce, 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- 

 gidce, and also with the Phileurideous Dynastidce, which last are re- 

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

 antennfe, 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. 



Cr}'ptodus Tasmannianus, W. Niger, nitidus, oblongus, punctatus, 

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

 tice producto, margine unticu fere recto. Long. corp. lin. 9-^.
