At the time spinosa was described attention was called to the structural 
differences between this species and parallela Grt. In the light of the 
writer’s present studies these seem of generic value and he, therefore, 
proposes the above generic name. As yet no males of the genotype have 
been seen and, therefore, no comment can be made on the male genitalia, 
but the heavy spining, as indicated by the name spinosa, is sufficient to 
distinguish the genus readily from Trichorthosia. 
Trichofeltia gen. nov. 
Type, Agrotis circumdata Grt. 
Eyes strongly hairy. Palpi upturned, the third joint somewhat 
porrect; second joint with strong fringe of hair below, third joint rather 
long and smooth-scaled. Front smooth. Male antenna? strongly lamellate, 
giving the appearance of being bipectinate. Fore tibia scarcely twice as 
long as first tarsal joint, unspinecl on inner side, but with two or three 
apical spines on the outer side and weak hair-fringe proximally. Mid and 
hind tibiae moderately well spined. No fourth row of spines on mid tarsus. 
Yestiture of thorax rather rough, hairy, without noticeable tufting. 
Figure 40. Male genitalia of Trichofeltia circumdata Grt. 
Male Genitalia. Clasper of moderate width throughout, with a strong 
sacculus projecting slightly at base over costa; apex of clasper rounded, 
with hair-fringe but no corona; harpe a very stout, slightly twisted, 
chitinous bar, situated subapically; ampulla free, strong, forming a re- 
curved hook ventrad of the harpe. Clavus absent. Juxta a diamond-shaped 
plate with strongly pointed base and apex. Uncus short, broadly spatulate. 
Vesica armed with bundles of long and short cornuti. 
Circumdata is the only species included in this genus which is 
obviously related to Trichorthosia and Mimobarathra in the type of 
genitalia but retains a few spines on the fore tibia; in contradistinction to 
the usual condition in the Agrotids these spines are on the outer side. 
Heretofore the hairy eyes in circumdata have been overlooked, resulting 
in its misplacement in Feltia.
