and did not profess to be, other tlian identical witb Klug'a 

 Ophionea. When, in 1825, Dejean publislied the first volume 

 of iiis ' Species General/ he introduced the genus Casnonia at 

 p. 170, and, referring to the species included in it, he writes 

 " Latreille les avait d'abord places parmi les Agra, et il en a 

 fait ensuite un genre particulier que je lui ai conserve ; Klug, 

 n'iiyaut pas connaissance de son travail, Pavait ^tabli dans 

 son Entomologice hrasiliance sp'cimen, sous le nom d^ OpMo- 

 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 vaiii, nor can I find any references anterior to 1822 in tlie 

 works of other authors. The name was undoubtedly known, 

 for it appears (under the guise of Cosnania) in Dejean's fir.st 

 Catalogue (1821). I think Casnonia must be ruled out as a 

 pure synonym. 



In 1829 E^chscholtz, Zool. Atl. ii. p. 5, in introducing his 

 genus lihagocrepis^ gives a table diflferentiating this and 

 allied genera. Ophionea figures in this table as having tarsi 

 with a bilobed fourth joint ; the actual species, 0. cyano- 

 cephaldy 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. Ophionea in this sense was 

 recognized both by Schniidt-Goebel, Faun. Col. Birm. 184(3, 

 p. 20, and Lacordaire, Gen. Col. i. 185-4, p. 73, though both 

 of them were inclined to attribute the genus to Eschscholtz. 

 Another genus, also for 0. cyanocephala^ F., was formed by 

 Castelnau, Et. Ent. 1834, p. 40, under the name of Casnoidea, 

 but this merely provides another synonym for Ophionea. 



Mr. Bedel has already drawn attention, Bull. Boc. 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 Ophiunea, and puts all the 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 otiier hand, 

 in his table of the Australian Odacanthini, Proc. Linn. Soc. 

 N.S.W. 1917, p. 414, retains Ophionea as defined by Esch- 

 scholtz, and also, bke me, considers Motschulsky's genus 

 Laclinoihorax, Et. Ent. 1862, p. 48, as distinct from the 

 otiier genera cited*. 



* I may mention here that on a separate of his paper kindly sent me 

 by Mr. Bedel there is a note to the effect tliat cyanncephala, F. = Attf- 

 lubua indicus, Thunb. Nov. Ins. Spec, part 3, 1784, p. 68, fig. 81, describfd 

 from "lud. Orient." This I have confirmed, as far as the slendt-r 

 d'-scription allow-s of confirmation.
