Hipparchiscus. Walsh, Proc. Bost. Soc. Nat. Hist. Vol. 9, p. 3oo (1864). 
Anaplodes. Packard, Mon. Geom. U. S. ^. p. 392 (1576). 
Characters. — Face smooth. Palpus rather short to moderate. second joint somewhat rough- 
scaled beneath, third joint short or rather so in C', short to moderate in Q. Tongue present. Antenna 
in gf bipectinate, apex nearly simple, in 9 nearly simple. Pectus somewhat hairy. Hindtibia in gr 
more or less dilated, with hair-pencil r), usually also with a terminal process, in both sexes with all 
spurs. Abdomen not crested. Frenulum arising from before a slight basal dilatation, but present in both 
sexes (in c slender, not long). Forewing with costa more or less arched, apex moderate. termen entire, 
oblique, nearly straight to slightly curved, cell somewhat less than one-half,, DC? incurved (often 
strongly), SC! anastomosing with C, or free, SC? normal, R! about connate, M! separate; hindwing 
with apex moderately rounded, termen rounded, sometimes slightly ventricose in middle, but never with 
appreciable angle or elbow at R?, cell short, DC? oblique, C approximated to cell to rather less than 
one-half, rather rapidly diverging, SC? stalked, sometimes connate or separate. 
Ecc. — Elliptical, lat above and below, one end a little depressed. no truncation. The hexagonal 
reticulation slight. Colour shining ochraceous, changing to reddish. Duration nine days (Dvar, PsycAe, 
Vol. 11, p. 121, on dariniata). 
LaRvA. — Head rounded bilobed, granular. Body flattened, winged with lateral projections, 
surface spicular, tubercles and setze small, obsolete in latest stadia, the setae with swollen tips, 
II especially flattened fan-shaped and cleft at tip. Does not bear any attached objects (Dyar, loc. cit., 
a full description of the five stadia of darwiniafa). Feeds on trees, etc. Others of the larvze are known. 
"That of the type species is figured by Packard. t. 13, f. 28. 
Pura. — Apparently not fully described. That of mimosaria rather slender, light brown, much 
dotted with fuscous, anal spine short, moderately stout, with eight unequal curved slender spinules 
(Walsh, Proc. Bost. Soc. Nat. Hist. Vol. 9, p. 3or; Packard, Amer. Nat. Vol. 18, p. 934). 
As above mentioned, this genus is doubtfully differentiable from certain forms in the preceding, 
although the extremes (as Pis/acraria), with quite small third joint of palpus in both sexes, are very 
distinct from normal RacAeosPila. Packard distinguishes A /lodes (1. e. typical Nemoria) by its narrow face, 
but makes the face less narrow in 4zaflodes (which we do not consider tenable generically); we have 
found too much variation in width in both genera to be able to make any use at all of this distinction. 
Type of the genus : Nenoria bistriaría, Hübner (Moore sel., 1887).
