All these species are so closely allied in type of male genitalia to 
segetum (vide Pierce, op. cit., PL XVI) and to one another that frequently a 
specific differentiation, based on this character, is not possible. The last 
three species are somewhat atypical but, in the opinion of the writer, are 
sufficiently allied to be included under the one generic head. In nialefida 
and ypsilon the palpi lack the rough hairs beneath the second joint, being 
heavily and closely scaled; ypsilon further is unique in having a smooth 
front, and in the genitalia of both we find the costal margin curved upward 
apically far more than in any of the other species. Manifesto, would seem 
at first rather misplaced, due to its distinctly hairier vestiture, but the 
writer can find no better position for it unless it be transposed to Feltia. 
On genitalic characters it is not misplaced here, although it is still more 
closely allied to Trichosilia acarnea Sm., a hairy-eyed species. It might 
also be noted that the fore tibia is distinctly longer than the first tarsal 
joint. 
With regard to Porosagrotis , the only possible way of retaining this 
generic name would be on the strength of the fasciculate male antennae of 
the genotype, vetusta, as differentiated from the normal bipectinate type; 
this seems scarcely sufficient. 
Feltia Wlk. 
1856, Cat. Lep. Het. Brit. Mus. IX, 202 (type, ducens Wlk.). 
Eyes naked. Palpi upturned with third joint conical, more or less 
porrect; second joint normally with long, heavy scaling beneath, projecting 
forward apically into a conical tuft; third joint with traces of a similar 
tuft. Front normally smooth (occasionally slightly tuberculate). Male 
antennse serrate and fasciculate, with normally two tufts at the extremity 
of each lamella. Tibi® all spined, the fore tibia subequal in length to first 
tarsal joint, smooth-scaled, with complete row of spines on each side, the 
terminal spines being strongest. Mid tarsi with fourth row of lateral 
spines as in Agrotis. Vestiture of thorax rather smooth-scaled with im- 
prominent tufting.
