Remark. — I am indebted to the kindness of M. Louis Ooulon, 

 Director of the Museum at Neufchatel, for the loan of this species, 

 for the purpose of figuring in my monograph : it is the only specimen 

 I have seen, and in all probability is the only one that has been sent 

 to Europe ; it is a bird whose rarity is only equalled by its beauty : 

 it is very nearly allied to Callipepla Californica, but is distinguished 

 from that bird by the straight form of the crest, the rich colouring of 

 the flank-feathers, by the absence of the scale-like markings of the 

 abdomen, and the greater length of the tail. 



ENTOMOLOGICAL SOCIETY. 

 May 5th, 1845.— The Rev. F. W. Hope, President, in the Chair. 



Captain Parry exhibited a small collection of insects chiefly from 

 New Holland; also an exotic Curculio, with two long Clavarite 

 springing from the elytra and thorax. 



The President exhibited a large Ant Lion in spirits from the plains 

 of Marathon. 



Mr. C. Lamb exhibited a specimen of Deinacrida heteracantha in 

 spirits, remarkable for its immense mandibles. 



Mr. S. Stevens described a plan of setting the wings of moths so 

 as to give them a curved and somewhat deflexed appearance, by cut- 

 ting a groove down the centre of the narrow setting-board (in which 

 the body of the insect is lodged), and giving the sides the proper 

 deflexed curve. 



The following papers were read : — 



" On the genus Holoparamecus of Curtis." By J. O. West wood. 



After detailing the history of the establishment of this genus, and 

 its identity with the genera Calyptobium, Villa, Amphibolonarzron,
