476 Mr. H. E. Andrewes on Oriental Carabide. 
and did not profess to be, other than identical with Klug’s 
Ophionea. When, in 1825, Dejean published the first volume 
of his ‘ Species Général, he introduced the genus Casnonia at 
p. 170, and, referring to the species included in it, he writes 
« Latreille les avait d’abord placés parmi les Agra, et ilena 
fait ensuite un genre particulier que je luiai conservé; Klug, 
n’ayant pas connaissance de son travail, avait établi dans 
son Entomologia brasilian specimen, sous le nom d’ Ophio- 
nea.’ Klug could not in 1821 have any knowledge of a 
work published in 1822, and Dejean must therefore refer 
to some earlier work of Latreille. I have searched for this 
in vain, nor can I find any references anterior to 1822 in the 
works of other authors, The name was undoubtedly known, 
for it appears (under the guise of Cosnania) in Dejean’s first 
Catalogue (1821). I think Casnonia must be ruled out as a 
pure synonym. 
In 1829 Eschscholtz, Zool. Atl. 11. p. 5, in introducing his 
genus /thagocrepis, gives a table differentiating this and 
allied genera. Op/Azonea figures in this table as having tarsi 
with a bilobed fourth joint; the actual species, O. cyano- 
cephala, F'., is not mentioned, but it is none the less made 
the genotype, and the fact that Casnonia is included in the 
same table (with a different signification) does not seem to 
me to invalidate this conclusion. Ophzonea in this sense was 
recognized both by Schmidt-Goebel, Faun. Col. Birm. 1846, 
p- 20, and Lacordaire, Gen, Col. 1. 1854, p. 78, though both 
of them were inclined to attribute the genus to Eschscholtz. 
Another genus, also for O. cyanocephala, F., was formed by 
Castelnau, Et. Ent. 1834, p. 40, under ihememe of Casnoidea, 
but this merely provides another synonym for Ophionea. 
Mr. Bedel has already drawn attention, Bull. Soe. Ent. Fr. 
1910, p. 72, to some of the details given above, but he does 
not come to the same conclusion. He makes pennsylvanica 
the type of Ophionea, and puts all tie species with a cleft 
fourth tarsal joint under Castelnau’s genus Casnoidea. In 
this he has been followed by Commandant Dupuis, Ann. Soc. 
Ent. Belg. 1913, p. 270. Mr. Sloane, on the other hand, 
in his table of the Australian Odacanthini, Proc. Linn. Soe. 
N.S.W. 1917, p. 414, retains Ophionea as defined by Esch- 
scholtz, and also, like me, considers Motschulsky’s genus 
Lachnothoraz, Kt. Ent. 1862, p. 48, as distinct from the 
other genera cited *, 
* IT may mention here that on a separate of his paper kindly sent me 
by Mr. Bedel there is a note to the effect that cyanocephala, F,= Atte- 
labus indicus, Thunb. Nov. Ins. Spec. part 3, 1784, p. 68, fig. 81, described 
from ‘Ind. Orient.” This I have confirmed, as foie as the slender 
d-seription allows of confirmation.
