March, 1914] FORBES : NOCTUID.E OF NORTH AMERICA. 31 



70. Albocostaliafa^ originally described as a geometer, referred 

 here on Dyar's authority. The type of Oniza is a very similar South 

 American species. 



71. Also sometimes placed in Fagifaiia. It seems out of place in 

 either. 



/2. Including Anorthodcs, Proxcniis, etc., Athctis of Hampson. 



73. I believe this is a true Deltoid, near Hypeiia. 



74. The genera of. this group are separated almost entirely on 

 male characters. Hypcnula can be distinguished from most of the 

 others by its blackish coloration, and long rough palpi with triangular 

 end- joint. ChytoUta is light clay-color with sinuous outer line, but 

 a couple of Zanclognatha are similar. ZanclognatJia can generally 

 be distinguished by its more distinctly curved palpi. Hormisa is 

 composed of three dissimilar species, one marked with straight trans- 

 verse lines, one with longitudinal bars, and the other similar to Chy- 

 toUta. Renia and Philomctra also come out here. 



75. Parastichtis of Smith but not of Hampson. 



y6. Here will come the species on our lists as Xylina, Calocampa, 

 Scopelosoma. Lithomia, Litholomia, Brachycosmia, (Anchocelis), 

 Glcca, Epiglcca, and those Orthosias placed by Hampson in Amathes. 

 The characters for individual genera as given by Lederer, Smith and 

 Hampson, are largely based on slight differences in the tufting, which 

 often fail in specimens with the thoracic parts in a slightly different 

 position, or the abdominal tufting, which is particularly evanescent 

 in the group, and varies within the genera as now understood; and 

 on the markings, which are differently interpreted in Europe and 

 America. The European species nearest to Papaipcma cerina for 

 instance, is there considered a Xanthia; those corresponding to Or- 

 tliosia (Amathes) hicolorago also as Xanthia^ while the type repre- 

 sented by our Xanthia piita and pulchella, is the European Orthosia. 

 There is quite a little variation in wing-form and markings in the 

 two overlapping genera Xylina (GrapholitJia) and Episilia {Scope- 

 losoma plus Glara in part) sufficient to cover the other nominal genera. 

 Not enough of the larvae are known to help much, but those of 

 Scopelosoma are of two widely divergent types, one agreeing with 

 Jodia and Amathes in a general way, the other unique. 



yy. Limbolaris is, so far as I can see, a typical Syneda, and was 

 placed there until Smith's catalogue was published. 



78. Often misspelled " Eiicalyptera."
