29. CEnotnis is not really distinct from Stamnodes, but the coloring 

 is different. The type species, dispar, has much more red than ours, 

 and superficially looks like some Eudules. Emplocia cannot be used 

 as its type is an Ennomid. 



30. Cocnocalpe in part of Hulst, but differing in the smooth front, 

 shorter palpi and in the simple pattern of the upper side. The two 

 genera perhaps represent the most primitive of living Hydriomeninae. 

 So far. as examined the genitalia are also closely similar. In the 

 more alpine species the head and body tend to become more hairy, 

 especially in the closely related South American genus Heterusia, 

 and the genus becomes structurally identical with Hydriomena. Lis- 

 sopsis is based mainly on the characteristic pattern, and fervifactaria, 

 of our species, might be transferred to it. The species of Xanthorhoe 

 (petropJiora) with mdcv. long and bent also show the pattern of 

 Stamnodes, and I believe, should be transferred to it in spite of their 

 pectinate antennae; they are volucer, costimacula and rubrosuffusa of 

 our list, sistenata and jaspeata of the Neotropical, and, I think, 

 nephelias Meyr., of New Zealand, if I have it rightly identified. 



Callippia is similar, but expands over two inches, the patagia are 

 densely hairy, and there is hair on the palpi and face. Cophocerotis 

 is Stamnodes with unipectinate antennae; both from South America. 



31. Close both to Vcmisia and to Opcrophtera, group Paraptera: 

 the European species verherata appears to belong here, making the 

 connection with Venusia. 



32. I should separate Venusia from Euchocca by the course of 

 mdcv. of the hind wing rather than the male antennae, as it correlates 

 much better with the markings and genitalia; both types occur in 

 Europe with two accessory cells, verherata, mentioned above with a 

 long bent discocellular, and the genus Asthena with short nearly 

 straight ones. Some of the European species seem to grade into typ- 

 ical Hydriomena. 



Venusia in this sense will separate into three groups by antennal 

 characters: (i) Venusia proper, with pectinate antennse, contains V. 

 cambrica; (2) Nomenia, with the laminations long and narrow, those 

 of successive segments spaced apart from each other, includes uni- 

 pecta {12-lineata) , and secunda; and (3) a group containing comp- 

 taria, pearsalli (12-lineata) in this country, blomeri. and decolorata 

 in Europe and several Indian species. I suspect the name Hippolyte
