132 CRYPSITYLA. By L. B. Prout. 
As the proximal spurs of the $ hindtibia are obviously not of generic importance here, I have now made a 
slight further change, restricting Crypsityla to the 2 or 3 species which have the specialized scale-patch on 
the <$ hindwing. 
H. delotaria Hbn. (15 f). Hubner's figure, of a § from Surinam, seems much too brightly coloured 
(too yellow, the “sanguineous” markings brighter than in any specimen which I have seen), but otherwise 
good. Face red, fringes rosy, the reddish costa and lines normally much irrorated with blackish. Hincltarsus 
of $ short, the long tibial pencil reaching far beyond it; hindtibia of $ with proximal spurs fully developed. 
Abdomen of with lateral tufts not strong, excepting the one just behind the tympanum. Forewing with 
2nd radial arising much before middle of discocellulars. Venezuela, the Guianas and the Amazon; 1 $ also 
from Coca, Upper Rio Napo. — ustaria Gum. (15f) is almost certainly nothing but a small, well-marked 
with the head, costal edge and even the subcostal suffusion strongly black-mixed, so that Guenee calls their 
colour “scorched violaceous" rather than reddish. Structure the same, termen of hindwing perhaps slightly 
less gibbous; apical mark of hindwing slender. Cayenne, 1 
H. lophopleura sp. n. (15 f), formerly misidentified as delotaria, differs in its more rounded hindwing 
and in several structural characters: palpus and <$ antennal ciliation a little shorter; hindleg of $ with the 
femur apparently fused to the body, the tibia and tarsus less short than in delotaria , stouter, the $ tibia with 
the outer proximal spur short; $ abdomen with very large latero-ventral tufts; forewing with 2nd radial more 
central. Belize, British Honduras, type <3 hi the British Museum. A short series from Orizaba, not perfectly 
fresh, in the Tring Museum. Possibly a smaller, paler race of partita , with the cell-mark of the forewing slender, 
linear, the markings of the hindwing almost obsolete; but the lateral tufts of the $ abdomen are apparently 
still stronger. The $ cannot be compared, as that of partita seems to be still unknown. 
H. partita Dogn. (15 f). Very much like a larger, broader-winged Crypsityla micaceata (f. birnaculata) 
but without the special scale-tuft on the J hindwing; hindwing with the termen somewhat more gibbous 
(though without the definite bend of delotaria), markings rather stronger (the hindwing with 3 lines), the ter¬ 
minal dark line less regular; cell-spot of forewing strong, oval, blackish. Abdomen of the $ with strong tufts, 
approaching those of lophopleura. Ecuador to Bolivia, the type from Loja. 
H. imitans Dogn. (15 f). Brighter ochreous than its congeners; median line and cell-spot faint or ob¬ 
solete. Hindleg of 3 less short, the tibia approaching the femur in length, the tarsus moderately long, slender; 
of $, according to Dognin, in litt., with 3 spurs. 3 abdomen without strong tufts; genitalia with the valves 
asymmetrical. Superficially recalls a small Semaeopus bimacula (11 c), but with many obvious differences. 
The GG are fairly common from Ecuador (loc. typ.) to Bolivia: known also from Costa Rica. 
32. Genus: Crypsityla Warr. 
Perhaps a section of the preceding. Warren, in erecting it, says that the $ hindtibia has only 3 spurs. 
I accept this statement , but cannot find a $ of the genotype ( quinquelineata) in any collection here and learn 
that sex is also wanting from the Dognin and Schaus collections; that of the very similar mantaria has 4 strong 
spurs. Warren, however, founded the genus chiefly on the secondary sexual characters of the q ; forefemur 
in $ with a tuft from base, base of abdomen tufted beneath, hindwing with large tufts of coarse hair beneath, 
at base of cell. Forewing with 1st subcostal arising rather far proximad, 2nd subcostal from cell or connate 
(perhaps occasionally stalked), 2nd radial slightly before middle of discocellulars. 
C. micaceata Walk. (15 g). Named from the copious scintillating scales. $ structure much as in quinque¬ 
lineata, brat the specialized scale-patch of the hindwing is not overhung with tufts of hair. Widely distributed 
but scarce; I have seen it from Venezuela (type), Matto Grosso, Bolivia, N. Argentina and Paraguay and 5 
from Castro and Rio Paranapanema. The type and a Ciudad Bolivar belong to rather a small, cleaner form, 
the outer blotch between the radials wanting. — The rest may be known as birnaculata /. (? subsp.) nov. 
Terminal blotches well developed. Type $ in the British Museum, from Sapucay, Paraguay. 
C. mantaria E. D. Jones (15 g), founded on a $ from Castro, is darker than micaceata , the scintillating 
scales less copious; otherwise very similar. The type is in addition larger, but this does not apply to the Ypi- 
ranga $ here figured, which, on the other hand, is still darker. A from Rio may be associated with them; 
but I have begun to suspect that mantaria may be the normal $ form of micaceata and the last-mentioned 
an aberration of the same with $ colouring. 
C. quinquelineata Dogn. (= confusaria Prout, ex Dogn. MS.) (15 g). Larger than the two preceding, 
more variegated and with pale costal margin. Much like Acratodes exaeta, which lacks the special tufts; darker 
than that species, forewing with 2nd subcostal from the cell (in exaeta stalked). Ecuador (type) to Bolivia. 
The new name was proposed under the erroneous idea that quinquelineata was preoccupied.
