RACHEOSPILA. By L. B. Peout.

R. viridilinea Prout (3 h). Postmedian line much less dentate than in vividata, behind the 2nd median viridilinea. 
of the fore wing almost straight (in the two preceding species deeply incurved), fore wing beneath with the 
green of distal area more extended than in vividata, hindwing beneath with the green line much stronger, at 
the medians rather strongly projecting; 1st median connate or very shortly stalked. Hindtibial process of ^ 
longer, almost as in latuta. Carabaya; Santo Domingo. — cushiensis subsp. nov. is a somewhat enigmatical cushiensis. 
form, with the termen of the forewing slightly more oblique, that of the hindwing scarcely bent, the ground¬ 
colour above slightly paler, with the cell-dots smaller. Cushi, Huanuco, E. Peru, type and others in Mus. 
Tring. I have also a large $ from Huancabamba, Cerro de Pasco, of the cushiensis form but with the cell-dots 
not reduced. 
R. montana is a more thinly scaled species from high altitudes, the white abdominal dots small, the 
postmedian line dentate, but much more slightly than in latuta, the terminal reddish line present, but inter¬ 
rupted at the veins. Three forms seem clearly differentiable. — montana Prout (3 h), from Agualani, Carabaya montana. 
(9000 feet), has a slightly bluer tinge than the other forms, the white lines a little thickened. — araeomita nom. uraeomitu. 
nov. (= tenuilinea Prout, nec Kaye), from Oconeque, Carabaya (7000 feet), has the lines quite slender. — 
smaragdina Prout, from Huancabamba, Cerro de Pasco. E. Peru, has the lines still more slender, the ground- smaragdina. 
colour brighter green, the scaling not quite so thin. 
R. carmen Prout (3 h). Similar to montana, but with the postmedian line as free from denticulation carmen. 
as in viridilinea, similarly straight at the fold of the forewing and curved inward to costa. Hindtibial process 
short, rather more so than in montana. Forewing with 1st subcostal anastomosing with costal more constantly. 
Costal margin of fore wing beneath strongly darkened in proximal half. E. Peru: Cushi and Huancabamba 
(Cerro de Pasco). 
R. cecilia Prout differs structurally from the two preceding in that the hindtibia is not dilated, the cecilia. 
terminal process wanting; superficially in that the cell-dots are wanting. Eorewing with 1st subcostal free. 
Lines at least is non-crenulate as in carmen, the postmedian on the forewing slightly less curved to costa, on 
the hindwing a little less outbent behind the middle. Cushi, Huanuco, 1820 m, only the type known. 
R. ella Prout. A rather small species (24 mm), with the wings relatively broad and short. The elta. 
markings of the abdomen and wings may be compared to those of latuta, with rather strong cell-dots, but 
there is no terminal line, only white dots at the veins, as in viridifimbria (3 g), with which species it shares the 
green fringes, though they show here a slender w'hite line at their base. Hindtibial process rather long, reaching 
beyond middle of 1st tarsal joint. Colombia: Torne, Cauca Valley, only the type known. 
R. dorsilinea Schaus is unique in having a continuous white line from hind part of thorax along the dorsilinea. 
abdomen. Face red-brown. Cell-dots minute. The usual lines (including the reddish terminal) fine, the post¬ 
medianonforewing parallel with termen. Hindwing with 1st median about connate. Expanse 25 mm. Costa Rica. 
R. eugethes Prout is in some respects an anomalous species. The wing-shape, scaling and venation (1st eugethes. 
median of hinclwing connate) associate it definitely with the present group, but the first white abdominal 
spot is bordered with bright red anteriorly and laterally, and the other three stand on a duller red patch - 
characters w r hich suggest a connection with the lixaria or with the albociliaria group. The punctiform white 
markings are identical with those of diarita (3 g), unless rather smaller; expanse 30 mm; cell-dots slightly 
redder than in that species; antennal pectinations a little shorter. Huancabamba, Cerro de Pasco, only the 
type known. 
inaequalis- group. 
Abdomen with white, red-encircled spots. Wing-margins more ventricose than in the lixaria and 
albociliaria groups. Hindwing with 1st median connate or just separate. 
R. inaequalis Prout (5 b). An interesting species, with the borders beginning to suggest the lafayaria inaequalis. 
group, from which it differs in the green face and abdomen. 1st median of hindwing just separate, thus inter¬ 
mediate between the lixaria and albociliaria groups. $ antennal pectinations scarcely as long as diameter of 
shaft. Hindlegs unfortunately lost in the unique type. Santo Domingo, Carabaya, S.E. Peru. 
R. prava sp. n. (3 h). Evidently related to inaequalis, agreeing essentially in shape and structure, prava. 
Differs chiefly in its considerably smaller size, relatively larger cell-spots and simple terminal line. Hindtibia 
without hair-pencil or terminal process. Hindwing with 1st median connate (type) or just separate (paratype). 
The type is a sport in venation, the costal of both wings forking a little beyond the end of the cell, both 
arms of the fork strong and reaching the costa. Bolivia: Prov. del Sara, Dep. Sta. Cruz, 450 m. (J. Stein- 
bach), type (J; Brazil: Uberaba, Minas Geraes. Both are in the Joicey collection, the proximal part of the 
wings unfortunately discoloured in relaxing.
