HAMALIA. By L. B. Prout.

reddish, the very broad median area of the forewing projecting much more strongly, receding from the termen 
in its anterior part, so that its author even likened it to admirabilis rather than to adela. Panama to Bolivia, 
described from Loja. 
A. exaeta Proid (15 e). Larger than pulida, the forewing with a more rusty admixture and with pale exaeta. 
costal margin beginning to recall admirabilis. Markings not very strong, not very irregular; the elongate, 
rusty, dark-spotted cell-mark of the hindwing conspicuous. La Oroya, Rio Inambari, the type <$, and Quinton, 
Carabaya, 1 no others known. 
A. admirabilis Oberth. (15 e). Again considerably larger, very distinct in shape and markings. Hind- admirabilis. 
wing beneath with a dark fuscous subterminal band, which continues as a small tornal patch on the forewing. 
Ecuador to Bolivia, the type from Peru. — brasiliana subsp. nov. Distinguished by its deeper colouring (es- brasiliana. 
pecially in the $$) and the more extended pale borderings of the forewing; in particular, the postmedian line 
begins to bend proximad somewhat earlier and the enlarged pale tornal space is cleaner. On the underside 
the fuscous tornal spot is correspondingly broadened. Santa Catharina: Jaragua do Sul (F. Hoffmann) a 
good series in the Tring Museum. A worn $ from Alto da Serra, Sao Paulo, is similar. 
A. angulata Schaus (15 e) differs in its irregularly shaped wings, the hindwing with a prominent tooth angulata. 
at the 1st radial. The pale part of the hindwing is more hyaline. Costa Rica (type), British Honduras, Panama 
and Ecuador. 
A. grays sp. n. (15 e). At first sight closely like a small, poorly coloured admirabilis. Distal margins grays. 
slightly more convex, especially that of the hindwing, which even shows a faint angle at the 1st radial, fore¬ 
shadowing the tooth of angulata. ForeAving with the costal part more greyish, less contrasting, the markings 
almost reaching the costal edge, the median streak darker and less oblique than in admirabilis. Hindwing 
beneath with the subterminal band much less uniform in width, anteriorly 2 mm, reducing to less than 1 mm 
behind 3rd radial, very slightly widened again behind 2nd median. Matto Grosso: Melgnira, 10 miles S. of 
Diamantino, 2000 feet, flying in original forest at night; type q in the British Museum. 
A. vitticostata Warr. (15f) seems to fit, by its structure, into this genus. Shape an exaggeration of vitticostata. 
that of angulata. Its very small size, bright colour and pure white cell-spot of the hind wing are noteworthy. 
Trinidad, the Guianas, the Amazon and into E. Peru; type from French Guiana. — versicolor subsp. nov. (15 f). versicolor. 
A trifle larger, with more purplish reflections; the broad costal border white in its anterior part, buff in its 
posterior; broader dark shades than in vitticostata; the sinuous dark-red outer line of the forewing (from costal 
border to 2nd median) replaced by a blackish one. Muzo, Colombia (A. H. Fassl), 10 <$<$; type in British 
Museum. Perhaps a species. 
A. griseocostata Warr. (15f). Closely similar, but with almost rounded hindwing; costal border of griseocostata. 
forewing more narrowed distally, scarcely reaching apex, its distal part more yellow; distal border scarcely 
separated by any dark shade from the ground-colour. W. Ecuador. 
A. aphilotima sp. n. (16 a). Head and body much as in admiranda , hindleg not quite so short and weak, aphilotima. 
tarsus about as long as tibia, not hairy. Belt at base of abdomen purer white. ForeAving with the cinnamon 
colour rather less bright, the narrow pale cell-mark scarcely dark-edged; a pale curved outer line succeeded 
distally by an irregular, narrow area of the groundcolour. Hindwing not hairy beneath; its scheme of mark¬ 
ings more as in the adela group, though with the pale postmedian line much nearer the distal margin, etc. 
Underside without markings. Matto Grosso (P. Germain), 1 in the British Museum. 
31. Genus: Hamalia Hbn. 
The few species which are left here, after the removal of my genus Ptychamalia (see below) and a few 
other obviously dissonant elements, still show considerable structural variation, though the pattern is pretty 
uniform and so different from the generally glossy Acratodes that it would be a mistake at present to sink the 
latter here. Colouring brown, the pattern simple, but with dark spots at micltermen and tornus of foreAving, 
the shape simple except that in the genotype (delotaria) there is a bend at the middle of the margin of the 
hindwing. Hindtibia of the d short, spurless, of the $ with 4 spurs or with 3 only. Abdomen of d more or 
less tufted laterally. Forewing with areole double, 2nd subcostal arising from cell; hindwing with 2nd subco¬ 
stal connate to quite shortly stalked. The genitalia of several so-called Hamalia Avere examined many years 
ago in collaboration with Messrs. Pierce and Burrows and revealed Avide disparities; after the elimination of 
Ptychamalia, with its simpler, more Sterrha-like structure, and a few species with bifid uncus, which went natu¬ 
rally into Semaeopus, there remained those with “abnormal” genital structures, still not very homogeneous, but 
with complicated developments of the 8th segment associating them more with the Scopula group than with 
Semaeopus or Sterrha. These were rather arbitrarly assigned to Hamalia or Crypsityla pending further revision.
