the inner margin of the fore wing, which is cream in sericea and pink 

 in pastUUcans. The pale lines on the veins sometimes fail, though 

 strong in a large majority of sericea, and rare in pastillicans. The 

 genitalia are strikingly different. 



44. Alctia. 



45. Includes CaUopistria, Euherrichia and Methorasa, with a great 

 variety of exotic forms. Group CaUopistria has angulate wings and 

 a knot in the male antennae; Euherrichia has angulate, and Methorasa 

 rounded, fore wings, with normal male antennae. 



- 46. Mcsolamia of Smith, Trigonophora of Hampson. 



47. In Wie case of Fagitana, Spragueia, etc., related species 

 indicate that MgCs) has disappeared /;/ situ, being sometimes indi- 

 cated by a slight thickening of the membrane and crowding of the 

 scales, only visible in stained and bleached specimens. In Characoma 

 it is probably M„ and Cu^ that have fused completely. 



48. Nyctcola rcvayana only. 



49. Characoma nilotica, according to Dyar, is an older name for 

 his Nycteola protceUa. It is a wide-spread subtropical species. 



50. The western species referred to Ceruia have nothing to do 

 with it, but belong more nearly to Bryocodia: so far as I know 

 C. cora is unique, having perhaps its closest relative in the even odder 

 Harrisiniemna trisignata. 



51. Also knovvn as Gortyna and Hydrcecia. Cerina seems not to 

 belong here, but is in every way, even to coloring, a Xanthia, closely 

 related to some European species. 



52. Tclcsilla of some lists, but quite different from the European 

 T. amcthystina. 



53. Also known as Erastria, and including Argillophora, which 

 does not seem to differ in structure. We have no really typical 

 Eustrotias, but most of our species are congeneric with L. bellicula. 

 The others are provided for elsewhere in the tables. 



54. Acontia. T. terminimacitla has a fovea and therefore belongs 

 to Hampson's first group. Group Tarachidia differs in the trifid vena- 

 tion of the hind wing. 



55. Separated from Bryophila by Hampson. 



56. This is almost deserving of a separate genus. Its relationships 

 seem more with Fagitana than Eustrotia, but I have no material for 

 dissection.
