92 Major F. J. Sidney Parry on 



My modified views respecting the limits of the genus 

 CladognatJius render it necessary to remove this species, 

 and 1 now locate it in Eurytrachelus, with certain species 

 to which it assimilates in the form of the mandibles, in 

 the structure of the head and clypeus, and especially in 

 the tuberculate head of the female (this last character 

 never occurring in the females of the genera composing 

 the Cladognathidce) . Its nearest ally in form is E. nipo- 

 ncnsis, Voll., and these two, with E. ruhroftuioratus, YoW., 

 from Japan, form a section of Eurytrachelus, possibly 

 representing the genus Macrodorcas of Motschulsky, and 

 I have almost arrived at the conclusion that Macrodorcas 

 rectus is identical with E. niponcnsis. Mr. C. Waterhouse 

 in his recent description of Macrodorcas opacus {vide 

 ante, p. 91) evidently indicates the same conclusion.

 Cladognathus elegans, Parry, Cat. p. 27, S ( ? incogn.). 



Unfortunately I am not in a position to state whether 

 the female has or has not the vertex of the head bi tuber- 

 culate, but in other respects it assimilates so closely with 

 the preceding as to lead me to refer it without hesitation 

 to the genus Enrytrachelvs, and to remove it from Cla- 

 dognathus where I formerly located it, but from which it 

 (litters widely in the structure of the head, clypeus, and 

 mandibles. This insect formed part of Mr. Bowring's 

 collection, and although the habitat of India was assigned 

 to it, I think it not unlikely that either China, Siam, or 

 one of the Islands in the Eastern Archipelago may event- 

 ually prove to be more correct. With respect to colour, 

 however, this species and the foregoing form an exception, 

 all the other members of this division of the family being 

 of a dusky brown or black hue. 



Dorcus (?) dcrelictus, Parry. (PL II. fig. 3.) 



Since the publication of my description of this singular 

 insect, of which the sex appeared to me doubtful, I have 

 been enabled by dissection to ascertain beyond doubt 

 that it is a female. The strongly bituberculate head 

 induced me formerly (with some hesitation) to place it 

 with the Dorridir, but I am now inclined, on account of 

 its uniform glossy and comparatively im2)uuctate surface,
