fusedly and not closely intermingled; in some specimens 
(apparently, from the few examples taken, males) a few of these 
are much larger than the rest and are placed near the suture 
along its front half. In the male the hind margin of the 
penultimate ventral segment is widely and sinuously emarginate.

MACROURA. 
M. Baileyi, Blackb. In Trans. Roy. Soc. 8.A., 1894, p. 204, 
I stated that this species seemed to be identical with Carpophilus 
obscurus, Macl., on the authority of a specimen sent to me by 
Mr. Lea and compared by him with Macleay’s type. I much 
regret to find that this was an error. I have since received the 
same species from Mr. Masters as Witedula concolor, Macl., and 
on investigation I find that the latter name is right and that 
Mr. Lea’s label must have been a /apsus calami or by some over- 
sight have been attached to the wrong specimen. I therefore 
must withdraw my assertion regarding C. obscurus, Macl., and 
notify that it is Wetedula concolor, Macl., to which it applies.

This fine species is in most respects very much like O. feroz, 
Har., but differs from it in the shape of the frontal horn of the 
male which is a transverse lamina (not much wider however 
than high), rugulose on its face and smooth on its hind surface, 
soutline (viewed from the front) forming three triangles one 
on each side with its apex directed outward and one on the top 
with its apex directed upward; the rugulosity of the prothorax
