66 Major Parry’s Catalogue 
to some of the sub-genera belonging to the Dynastide, and already 
alluded to by various authors, renders it somewhat perplexing to 
assign for it any satisfactory place among the Lucanoid Coleoptera. 
Mr. White (1. ¢.) remarks that this insect approximates both 
to Lamprima and Rhyssonotus. Professor Westwood, in his notice 
of the species (vid. Tr. Ent. Soc., N.S., vol. 3, p. 213), regards 
it as an obscure representative of Sphenognathus, with the mouth 
of a Sinodendron, alluding at the same time to the female as being 
apterous; and, finally, Monsieur Lacordaire, in his invaluable 
work on the Genera of Coleoptera, to which I have already had 
such frequent occasion to allude, although placing it with the 
Lamprimide, mentions that from the remarkable character of its 
legs the species appears to be rather allied to the Dynastide than 
to the Lucanide. In this view I am disposed to coincide, but 
have nevertheless, under the circumstances, placed it provisionally 
at the end of my arrangement, immediately after the genus Sino- 
dendron, thus establishing the connecting link between the Luca- 
noid Coleoptera and the Dynastide. 
Norr.—At one or two recent meetings of the Entomological Society, ‘“ di- 
morphism” or “‘ polymorphism” has been the subject of discussion. This 
singular phenomenon is very marked in the Lucanoid Coleoptera; and 
the existence of diverse forms of the same species, often exhibiting dif- 
ferences in their structural characters, renders necessary an acquaintance 
with a series of varieties of each separate species before we can arrive at 
a correct classification of this interesting group.—F. J. S. P., May, 1864.
