THE CANADIAN ENTOMOLOGIST. 27 



The North American hairy-eyed genera allied .to Tcefiiocampa are, further, 

 Crocigrapha, with a tuft behind the collar ; Ort/iodes, Himella and 

 Morrisonia (the species of which latter curiously resemble Adinotia, but 

 seem to hibernate, being found early in the year on sallows); while I have 

 described American species belonging to the naked-eyed European genera 

 Parastichtis and Anchocelis. Naked-eyed genera, with armed tibiae, are 

 Pachnobia and Metalepsis, occurring in both faunae, and PseudortJiosia^ 

 Choephora, Pseudoglaea, which seem to be American only. Trichor- 

 thosia, which has hairy eyes, seems to be more allied to Xanthia, or 

 Orthosia, in the shape of the wings ; but, if we do not divide this tribe, 

 as is perhaps unnecessary, it may be ranged with the. other hairy-eyed 

 genera, together with the somewhat aberrant Trichocosmia. The 

 principal genus is, perhaps, Orthosia, of which fourteen European and 

 seventeen American species are described, mostly of a European habitus, 

 and one representative, /errugineo ides. While I have referred one iden- 

 tical species (togata) to Xanthia, which, as distinct from Orthosia, con- 

 tains seven European species, the singular genus yi?^/^ Hub. i=^Hoporina 

 Boisd.), has an American representative of croceago in J. rufago Hiibn. 

 Eucirroedia is a modification of the European genus Cirroedia ; while the 

 peculiar genus Scoliopteryx with its one species, libatrix, is common to 

 Europe and America, from Hudson's Bay to Virginia, and is probably a 

 survival of the former circumpolar fauna. Glaea Hiibn. i=Orrhodia 

 Hiibn., Cerastis Tr.) has twelve European and only four American 

 species, but the nearly related American genus Epiglaea, which differs 

 from Glaea, much as Richia differs from Agrotis, by the presence, 

 namely, of a median thoracic ridge, has five, and Homoglaea two de- 

 scribed species. Our most beautiful species is H. carnosa, in which the 

 egg is also pink in colour. E. venustula is said to be the same as E. 

 sericea ; if the description of the latter is compared, it will be seen to 

 contradict that of E. venustula in important points, which remain incom- 

 prehensible if the two are really the same. The genera Ipimorpha and 

 Calymnia have representative, the genus Cosmia, an identical species, 

 paleacea. While there are a few peculiar genera in both fauna;, such as 

 Dicycla in Europe, and Zotheca in America, the affinities of the two faunae 

 in this tribe are strongly marked. The peculiar genus Scopelosoma has in 

 Europe one, in America nine species. Of these it is difficult to say which 

 is nearest to the European satellitia ; the identification of Guenee's sidus
