Cyparissias dedalus, Cram. 
Papilio dedalus, Cram. Pap. Exot. i. p. 1, figs. A, B (1775). 
This species appears to be much rarer in French Guiana 
than C. guyanensis, Houlb.

Cyparissias dedalus paraénsis, subsp. n. 
This form may easily be distinguished from the typical 
dedalus by the larger and more lunulate submarginal spots’ 
of the hind wing; these spots have the tendeney to be pro- 
duced along the nervules by yellowish scaling, and give the 
impression of an incomplete oval marking; the pale markings 
are also more yellowish than in dedalus.

(1917). 
Considerable confusion has arisen over this species, described 
by Houlbert (doe. cit.). In his “ Revision of the Castniinge ” 
(Etudes Lép. Comp. xv. p. 92) he treats dedalus, Cram., as 
an insect unknown in collections. Jordan (in Novit. Zool. 
xxiv. p. 59, 1917) described a species under the name of 
grandis, aud pointed out that the chief difference (apart from 
the structure of the genitalia) is in the absence of white spots 
above first radian nervule of fore wing and in fore wing not 
having a hairy underside. 
Talbot, in his review of Houlbert’s work (Novit. Zool. 
XXvi. pp. 28-35), makes no mention of any species of the 
Cyparissias-group. 
Rothschild, in his Supplementary Notes (loc. cit. pp. 1-27), 
places guyanensis, Houlb., as a synonym of dedalus, Cram. 
When I arranged the Castniudee in’ Madame Fournier’s 
collection I*had at first followed Rothschild’s view, but on 
going carefully through it a second time, and eomparing the 
specimens determined as grandis, Jord., with the figure of 
guyanensis, Houlb., I felt almost certain that I had to deal 
with the same species.
