R. mustela Dmce (5 c) was formerly referred to Nemoria, but the discovery of the $ has shown it 
to be a true Racheospila. Hindtibia with process. Abdomen without white spots. Wings thinly scaled, the 
rosy terminal line not or little expanded. In the type form the straight white lines are accompanied by reddish 
vein-dots, and these in the $ (here figured) expand into conspicuous marks at the hindmargin. Mexico and 
Costa Rica. — vermiculata Dogn. (= monostigma Prout) has the cell-spots of the forewing more strongly 
developed, the red marks which accompany the lines reduced or almost obsolete. Colombia. 
R. cara Dyar is said to differ from mustela (5 c) in having a purple postmedian line and white spots on 
the abdomen. Mexico: Zacualpan. 
R. interlucens Schaus. Probably related to astraea (4f), but the $ pectinations short; the $ with 
antenna not pectinate, 3rd joint of palpus shortish. Quite distinct from that species and from astraeoides (4 f) 
and capysoides (5 c) in the red-brown vein-dots which mark the lines. Costa Rica. 
R. zernyi sp. n. (4h) is another subdiaphanous species which may best be assigned to this group, and 
likewise lacks expansions of the red terminal line, which is interrupted by white spots at the veins. The body, 
however, is quite as that of roseilinearia (3 i). Palpus rather short. Antennal pectinations at their longest 
scarcely over twice the diameter of the shaft. Hindtibia of the <$ with strong pencil and shortish process. Very 
distinct in the thick and strongly sinuous lines. Underside with the markings shadowy. Sao Paulo: Alto da 
Serra, 29—30 October 1927 (Dr. H. Ferny), type in Mus. Wien. A $ from the same locality (R. Spitz) in 
Mus. Tring, closely similar to the type. A pretty and very distinct species which, with roseilinearia (3 i), 
perhaps connects the albociliaria (2 h) — with the lafayaria- group. As, however, the $ palpus is abnormally 
short for a Racheospila , it is possible that its affinities have not yet been found. 1st median of hindwing 
short-stalked (in roseilinearia well separate). 
R. trianteris sp. n. (4 d) introduces the true lafayaria- group, a number of closely allied species with 
rather heavily scaled palpus, a small red or brown crest supplanting, or superimposed upon, the 2nd white 
abdominal spot, bright green, prettily bordered wings, the forewing with white costal margin, altogether 
suggestive of the Old-World Comibaena, from which they differ chiefly in the short pectinations, trianteris 
is distinguished from most of the following by the indistinctness of the pale abdominal spots, the small cell- 
dots and the shape of the borders, notably the projection at the 3rd radial. Underside with the markings 
weakened, on the hindwing posteriorly obsolete. Face and part of palpus blackish. Pectinations scarcely 
longer than diameter of shaft. 1 taken by I)r. Zerny with the preceding. 
R. sophrosyne sp. n. 34 mm. Pectinations almost as in short as in trianteris. Face not so dark, with 
a narrow green fringe above. Abdominal white spots I and 3 strong. Cell-dots quite small. Terminal spots 
different from those of abornata (4 b) in having fine yellowish edging proximally, the subapical of the forewing 
bounded anteriorly by the 1st subcostal, the posterior one on both wings small (about 1,5 mm wide), on 
hindwing not crossing the fold; all narrower beneath. Brazil: Rio, type $ in Mus. Brit.; Alto da Serra (R. 
Spitz), a in Mus. Tring, with the markings rather broader, especially the apical of the forewing, which 
reaches 2,5 mm. 
R. semiornata Warr. differs from trianteris in the reddish face and palpus, rather less short pectinations 
and in the markings. The name-typical race, from Panama (also Costa Rica), differs from the new race here 
figured in being rather smaller, with the markings a little larger. In both races, the marginal markings are 
of a more uniform tone than in trianteris and (especially) fallax. —- abornata sitbsp. nov. (4 b) differs as noted 
above. The tornal blotches beneath are weakened, but generally less so than in typical semiornata. Upper 
Rio Negro, E. Colombia, 800 m (A. H. Fassl), a few <$<$. Type in coll. Prout. 
R. dirninuta Dogn. Similar to spasrna (6 i) but rather smaller (30 mm). Abdomen similarly with only 
the anterior white dot. Wing-markings similarly disposed, but reduced in size; cell-dot punctiform; subapical 
of forewing not exceeding 2,5 mm in width, tornal not exceeding 3,5; on the hindwing the subapical hardly 
more than 2 mm at 1st radial, the anal reaching 3 mm at the 2nd median. Underside with the subapical spots 
well developed, that of the forewing as above, that of the hindwing reduced to 1,5 mm. Colombia: Popayan, 
1 <$. Specimens from Ecuador (Balzapamba and La Chima), the 26—28 mm, the $ 31, conform excellently 
to the description, except that — especially in the — the 3rd abdominal white spot is fully developed 
and the anal blotch of the hindwing slightly less broad. The $ has the blotches more purple than the <$<$. 
R. spasrna Dogn. (6 i). Face and palpus brown-reddish. Terminal markings rather more extended 
than in porcius (4 c), differenty coloured and formed; rather characteristic is the small terminal prong in cellule 2, 
attached at the posterior blotch. Colombia: San Antonio. — oroyana subsp. nov. has the markings somewhat 
more brightly coloured, the cell-spots less large, the blotch at the anal angle of hindwing also sometimes reduced. 
Carabaya, S. E. Peru: La Oroya, etc.; type in Mus. Tring. 
R. psittacina Prout (4 c). Face blackish, approaching that of pelops (4 d). Pectinations nearly as long as 
in porcius. Wings opaquer green, with the markings much darker, the posterior relatively reduced and more
