Characters. — Face smooth. Palpus moderate to rather long. second joint shortly rough-scaled, 
third joint smooth, in cf moderate, in Q long. Tongue present. Antenna in Of with rather short, even 
ciliation, in Q more minutely ciliated. Pectus slightly hairy. Femora glabrous. Hindtibia in cf dilated 
with hair-pencil, median spurs wanting, in Q with all spurs (except apparently in subexfressa and possibly 
subtusumbrata). Abdomen not crested (except in Pudentifimbria). Frenulum in Cf very slender and usually 
short, arising before well-marked basal expansion; in Q wanting. Wings smooth-scaled, sometimes in 
part subdiaphanous. Forewing with costa gently arched, apex moderate, termen rather straight anteriorly, 
then curved and becoming rather strongly oblique, cell short, DC somewhat incurved, C reaching costa 
unusually near apex, SC! stalked to beyond R!, short, running into C, SC? variable, either normal, or 
running into C, or wanting, or stalked to beyond SC*, R! stalked, M! connate or short-stalked ; hindwing 
with apex moderate or rounded, termen angled or tailed at R? (in xantAochlora also with slight prominence 
at RÀ), tornus pronounced, inner margin rather long, cell short, DC slightly curved, SC? stalked, 
R? characteristic, M! well stalked, M? from close to end of cell, sometimes almost connate with stalk of 
R? to M! (PI. 3, Fig. 17). cf genitalia : uncus pointed, with slender curved socii of equal length, harpe 
with small hook near the base of the inner surface, costa of harpe clothed with long clubbed scales; 
penis pestillate. Related to CAlorissa, etc. 
Early stages unknown. 
Except in the curious variability of SC? of the forewing, and possibly the Q hindtibial armature 
of one or two species, a genus of very uniform structure. The variations of SC?, though they are — so 
far as we have observed — nearly always constant racially, can scarcely be treated as generic, as they 
sometimes separate forms so closely alike as to be scarcely otherwise distinguishable, while uniting 
forms much more widely divergent in facies (e. g. xantkochlora and. subexpressa). We have put the varia- 
tions on,record by dividing the genus into sections; Section III is probably intermediate towards 
H emithea. 
Type of the genus : Diflodesma celataria (Walker) — TAalera celataria, Walker (1896). 
Geographical distribution of species. — Indo-Australian. 
1) Pseudhemithea saturata, nov. Sp. — C, 24 mm. Face deep red. Palpus almost as long as diameter of eye, reddish. Antenna 
reddish, more ochreous proximally. Vertex and thorax dorsally (with base of abdomen) concolorous with wings. Breast and front of forecoxa red. Abdomen 
pale ochreous brown, mixed with red dorsally, second, third and fourth segments with red and black, crests rather strong, mixed with red and black. Wings 
rather dark blue-grey, slightly tinged with olive-green. Forewing with costal edge narrowly bright reddish ochreous, slightly spotted with fuscous; the 
lines and cell-spot olive-green; antemedian from costa before one-fourth, oblique outwards, irregular, rather thick, but very ill-defined ; postmedian 
thick, distinct except at costa, lunulate-dentate, projecting distad at R? and Mt, these teeth the sharpest, incurved between M! and SM?, only weakly 
outbent on SMe, slightly pale-edged distally, especially towards inner margin ; cell-spot rather large; fringe concolorous, with a very slender pale line at 
base. Hindwing similar, without antemedian line. Underside much paler, unmarked, the co:tal shade of forewing broader, especially at base. Ilesha, 
S. Nigeria (L. E. H. Humfrey). Type in coll. Brit. Mus. Excepting the rather longer palpus, the structure appears quite typical.
