The petiolated abdomen and two cubital areolets 

 combine to distinguish this group from all others in 

 Europe ; but exotic species exist having three cubital 

 areolets, and thus tending to coalesce with the next 

 subfamily. The Euphorides of Forster take their name 

 from E'uphorus pallidicornis, Nees, ranked by that author 

 erroneously among the Oxyura, subsequently transferred 

 by Haliday and Curtis to the Liophronides, and to its 

 present place by Reinhard and Forster simultaneously 

 (1862). In its most recent acceptation the group com- 

 prises Section I. of the genus Perilitus, Nees (Act. Ac. 

 L. C, 1819, p. 302), except his last species P. conjurigens, 

 which belongs to the Exodontes, genus Chcenusa. Hali- 

 day in 1835 (Ent. Mag., iii., pp. 34—38) made two 

 subgenera of Perilitus, which name he restricted to 

 Section I. of Nees, giving to Section II. a new name, 

 Meteorus. Wesmael, also in 1835, made two similar 

 divisions of Perilitus, Microctonus and Perilitus, whereof 

 the former represents Perilitus, Hal., and the latter 

 Meteorus, Hal. A Prodromus of a monograph of 

 Microctonus by Ruthe, containing only diagnoses, 

 appeared in the Stett. Zeit. for 185G (pp. 289—308), 

 of which Reinhard published a resume, with the addition 

 of all other known species, in the Berl. ent. Zeits., 1862 

 (pp. 321 — 329) ; the names adopted by Reinhard are 

 Perilitus for Section I. Nees, and Meteorus for Section II. 

 Westwood, in 1833, discovered Streblocera ; Ratzeburg, 

 in 1848, Cosmophorus ; and Forster (Verb. pr. Rheinl., 

 1862, p. 250) raised the total number of genera to 11. 

 The views of Haliday and Wesmael (1835), and of 

 Reinhard and Forster (1862) are substantially the same, 

 but the coincidence of dates causes a difficulty in the 

 choice of names. On the whole it seems preferable to 

 keep Perilitus (= Section I. Nees = Microctonus, Wesm.) 

 among the Euphorides, and to employ Haliday's Meteorus 

 for the next subfamily. It is necessary therefore, in 

 Part I., p. 10, for Subfam. 15, Perilitides, to read 

 Meteorides. Some additional descriptions of Euphorides 

 may be gathered from Curtis, B. E., 476, but they are 

 insufficient, except where further interpreted by Haliday ; 

 the species figured by Herrich-S chaffer (Fn. Germ., 156) 

 have been referred to their proper places by Reinhard.
