p. 372) ; the species usually referred to Eudidia are here assigned to 

 Euclidbnem, Hampson (type mi, Clerck), and Gonospileia, Hiibu. 

 (type munita, Hiibii.). Gbjphica, Linn., is included in the last- 

 named genus, and cceridea, (irote, in Euclidimera. Sohria, Walk., 

 which l)yar cites as a synonym of erichtea. Cram., under Drasteria, 

 Hiibn., is removed to crassiuscida, Haw., and placed in Ccenurgia, 

 Walk, (type convalescent, Guen.). 



The subfamily Mominaj comprises only seventy-four species and 

 eleven genera. Of the latter Ekeodes (type breviconiis, Walk.) and 

 Elydnodes (type variegata. Leech) are new. 



Coryli, Linn., the type of Demas, Steph., is also the type of 

 Calocasid, Hiibn. As the latter has two years' priority, it has been 

 adopted. Comobita, Esp., is the type of Diphthera, Treit. (182.5), 

 and also of Pa nthea, R'uhn. (1827) ; the former name has prece- 

 dence. It may be noted here that alpiaum, Osbeck, = orion, Esp., 

 so frequently referred by authors to Diphthera, Hiibn., has been 

 transferred to DaseocJueta, Warren, a genus belonging to the sub- 

 family Acronyctinoe (Phal. vol. viii. p. 30). 



Phytometrinae : two hundred and twenty-sis species, distributed 

 among fifteen genera (three new), are considered under this sub- 

 family heading. 



The bulk of the species hitherto referred to Plusia are here 

 placed in Phytometra, Haw. Amethystina, Hiibn., is noted as the 

 type of Plusia, Treit. (1826), and therefore takes precedence over 

 Telesilla, H.-S., a genus in Acronyctinse (Phal. vii. p. 587). 



Polychrysia,'H.uhu. (type moneta, Fabr.), is merged in Chrysoptera, 

 Latr. (type c-aureum, Knoch, = coar/ia, Eabr.). 



The last genus in this subfamily is Episema, Treit., of which 

 cceraleocejihala, Linn., is the type and sole known species. 



Sir George Hampson has formed his conclusions as to the rela- 

 tionship of families, genera, and species on a study of the venation 

 and other external characters of the imago. Possibly therefore his 

 classification of the Lepidoptera Phaltena) may not find unchallenged 

 acceptance. The fact, however, remains that, considering the 

 present state of knowledge concerning the early stages of the bulk 

 of the species, classification must be based almost entirely on 

 imaginal characters. Changes no doubt will be necessary as time 

 progresses, but, whatever these may be, we cannot conceive that 

 they will in any way lessen the importance or impair the excellence 

 of the ' Catalogue.' 



The scope of the work is far more comprehensive than is suggested 

 by its title. Not oidy is almost every species known to science 

 described, but, where necessary, figured in the atlas. Synonymy 

 and references are cited, and geographical distribution adequately 

 dealt with. 



The arrangement of the Phalaense in the British Museum Collection 

 being exactly that shown in the Catalogue, it follows that the latter 

 affords a very convenient clue to the position in the collection of 

 any family, genus, or species one may wish to study.
