57. The tvpical group, including jocosa and major, runs out here. 

 Momaphana comstocki with somewhat larger eyes and stronger 

 tongue, hardly deserves a separate genus. 



58. Here we run into the Hadcna and Orthosia groups. The 

 genera are largely ill-defined on their boundaries, though well marked 

 in their typical forms. Such as are particularly close to Hadcna 

 have been reviewed in this Journal, Vol. 21, p. 179. At this point 

 there will be difficulty with Apamca ercpta, which has the apex of 

 the fore wing rounded, but a perfectly even outer margin, and the 

 babitus of Apamca, and with A. veJata, whose apex is subfalcate, but 

 the outer margin distinctly wavy. 



59. Including Ptcrcctholix. m which the fovea is strongly devel- 

 oped, but not tcratophora, which is, I believe, a Bryocodia. 



60. Several other Orthosiids may possibly run out here, the genera 

 in this group being ill-defined. I believe this will prove congeneric 

 with the European Hoporina croccogo, both having the same wing- 

 form, tufts, and flattened abdomen. 



61. P. cxprimcns comes here, P. umbra has but a single abdominal 

 tuft. 



62. The type of Mctalcctra, M. prcccisalis, is extremely close to 

 our discalis. Typical Homopyralis (coiitracta) differs in having no 

 special tufting on the legs, and may be kept as a subgenus. 



6^. Chutapha of Ilampson, who transfers the name TrigonopJwra 

 to the iris group. 



64. P. xauthioidcs has normal palpi, and becomes so far as I can 

 see indistinguishible from Hadcna. Still it looks like a Pcngca. 



65. Differs from Actiiiofia (of Europe), with which it has been 

 united, in the unarmed tibin?. Too close to Hadcna. 



66. I do not believe these genera are distinct. 



67. A genus formed by Hampson for capax. Polia will run out 

 either here or with Hadcna, and some species seem closely related to 

 each. Group Etirotypc differs from Xylotypc in the pectinate anten- 

 nae, and the difference from Hadcna is perhaps in the tuft of hair- 

 scales on the basal joint of the antennae, simulating lashes. 



68. Grote fixed the type of Microco'lia as fragilis. This is an 

 Acronycta, typical of the smaller scalier group, so Hampson provides 

 the new name Lcuconycfa for diplitcroidcs. 



69. DipJiU'ia and Mama of our lists, but these belong to the Pan- 

 thcincT, while .■Igriopodcs is hardly distinct from Acronycta.
