wing venation of Ammoplilht, the author's specimen consequently would 

 appear to be an accidental variety in the wing venation, which also occurs in 

 other species ; and it follows of course, that Miscus is not tenable as a genus, 

 since it is impossible one species can stand in two genera. 



Pehp.fyulus is not indigenous in the South of France, but in South Ame- 

 rica, and the succeeding Pel. assimilis of the author does not appear to differ 

 from it. Spliex cinerascens of the author is Peps, obscura, F. 



Under Prion. Thorns two species are confounded, which occur in different 

 parts of America, viz. Enod. rustica, Nob., in North America; Enodia pagana, 

 Nob., in the South of Brazil ; on the other hand, it lias escaped the author 

 that Peps, crucis, F., is the female of his P. Thonue. The genus Trachypus, 

 Kl., does not belong to this family (vid. Report for 1841, p. 271), and just 

 as little should I be inclined to refer to it Psen and Mimesa. 



Fischer v. W. (1. c.) has described Ammophtta elongate, nitida, and Sphex 

 o/jsriifa, from the South of Russia. The latter is a puzzle to me, since the 

 abdominal peduncle is stated to be 2-joiuted. 



Guerin (Mag. de Zool. Ins. pi. 116) has figured a new Chlorion as Sphex 

 Paulinierii, and has described (ib.) AmmopMla cyaniventris as a new species ; 

 both from Senegal. 



AMPULICID.E. Dahlbom (Hym Eur. p. 29) elevates the genus Ampulex 

 to the rank of a separate family, without, however, fixing its characters. To 

 Am. compressa he adds a new species, A. Guerimi, the habitat of which (not 

 stated) is Central Africa. There can be no doubt that Ampulex, with some 

 allied forms, constitutes a peculiar group, wliich Westwood has recently 

 examined, in an essay announced in the ' Proceed. Eut. Soc.' as early as 

 1840, and given at large in the ' Transact. Ent. Soc.' (iii, p. 223), and has 

 since completed the knowledge of it in the 'Arcana Eutomol.' pi. 65. 

 According to these two memoirs, the group includes the following 

 genera : Ampulex, Jur. (the author calls the genus Chlorion, Lat., because 

 Latreille described the genus originally from Amp. femorata, although he 

 adduced Chi. lobatum as the type (since Latreille, however, afterwards him- 

 self admitted the genus Ampulex, and always retained Chi. lobatum as 

 Chlorion, it appears to me safer to follow Latreille's own definition), with 

 seven known species, of which Chi. cyanipes, Westw., is described more par- 

 ticularly in the 'Tr. Eut. Soc.' (p. 230.) Chi. purpureum, Westw., is 

 characterized and figured in the ' Arcana.' Trirogma, Westw. (vid. Report 

 for 1841, p. 273) ccerulea, from the East Indies, the $ is figured in the 

 ' Trans.', the ? in the ' Arcana ;' the former presents three abdominal 

 rings, the latter the usual number (6.) Amphelotoma (vid. Report for lS41 a 

 p. 273) tasmanica, from Van Diemen's Laud, the $ figured in the 'Arcana;' 

 the ? in the ' Transactions.' Lastly, a fourth new genus, Rhinopsis, in 

 the ' Arcana ;' with the clypeus prolonged anteriorly and pointed, only three
