Bares.—On a New Genera and Species of Heteromera. 283 
genus, totally removed from Opatrinus, and must be placed not far from 
Scotoderus, Perroud.* 
The Opatrum adil taliban White, evidently does not belong to that 
genus ; as M. Miedel, of Liége, is at present engaged upon a monograph of 
the Opatrides, I leave this in his hands. 
I have not as yet been able to consult the work by Blanchard containing 
the description of his Bolitophagus angulifer (from New Zealand) ; 1, how- 
ever, strongly suspect it to be identical with a species I have in my collec- 
tion, and which I refer to the genus Bradymerus, Perroud: this genus is 
placed by its author with the Bolitophagides ; to me it seems more natural 
to place it with the true Tenebrionides, 
T have received from Mr. Pascoe examples of the Selenopalpus cyaneus, 
Fab. ; these appear to me specifically identical with the type specimens (in 
my jegasedio’h of S. chalybeus, White. The characters of this genus lie 
rather in the form of the hind femora and tibie in the male (of whieh the 
former are strongly incrassated and somewhat arched, and the latter much 
thickened and strongly and acutely produced at the apex within) than in 
the form of the last joint of the maxillary palpi (in the same sex), as we 
find in some male examples of the Dryops (Ananca ?) strigipennis, White, a 
precisely similar form of palpus as in Selenopalpus cyaneus—t.e. the last 
joint strongly expanded, flattened, and with a deep semicircular excision at 
the outer edge. 
The Zolodinus zealandicus, Blanch., has the very exceptional character 
of having the hind margins of the third and fourth ventral segments 
corneous. + 
* The description of Scotoderus cancellatus, Perroud, very accurately applies to ex- 
amples of Iphthimus cancellatus, Montrouz., obtaine ed from the collection of Doué. 
Dechius, Pascoe, is but another name for Scotoderus; and Perroud’s, having priority, 
must stand. The mesocoxal cavities being widely open externally, revealing the trochan- 
tins, at once removes this genus from the position where Perroud has placed it, viz. in the 
vicinity of Antimachus (a genus of Ulomides); as I have previously stated (‘* Trans. Ent. 
Soc.,” 1868, p. 265), its true position appears to me to be near to Bius. The Scotoderus 
cancellatus is very near to aphodioides (Dechius), Pascoe, but may at once be separated 
from the latter by its smaller size, more finely punctured prothorax, the more distinctly 
crenated striw of the elytra (especially those by the suture), with the intervals distinctly 
punctulate.  Scissicollis (Dechius), mihi, may instantly be distinguished from both 
by its sparsely punctured and not at all rugose head, the very strong (and punctured) 
groove down the middle of its prothorax, the remainder of the surface of this part being 
almost impunctate 
}It is the same in the genus ati fe in another, allied but undescribed, South 
American genus; these somewhat against the value of this as a great divisional 
character, as laid down by Drs. Le Comte and Horn.
