c? ? . Generally mixed up in collection with suhhamata, from which it differs as 

 follows : 



A])ex of forewing jminted, not sinuate between SC* and SC'', i.e. not dentate at 

 S( !■'' ; underside paler, clayish. Tenth tergite (c?) less compressed at end. more 

 evenly rounded in side-view, sternite ratlier broader (PI. XLIV. f. 14. 16) ; process of 

 penis-sheath (PI. LIIl. f. 30) much less curved, its right edge not serrate, apex 

 bifid as in hopjferi.

Boisduval's specimens described in Lep. Gimtpmala,, I.e., are preserved in the 

 collection of Mons. (Jharles Oberthiir; the S is suhhamata, while the ? belongs to 

 the present species. If Boisdnval had not cited Felder's plate, and not clearly shown 

 by the synonymy that he adopted the name from Felder's plate in preference to his 

 own manuscript name — which, however, he could not persnade himself to suppress 

 altogether, jmblishing it among the synonyms in a distorted form — the name 

 caiiyinosa would have to be sunk as a synonym of suhhamata ; but as the facts 

 are, we must regard Felder's figure as the type of Boisduval's caliginosa, i.e. the 

 individual from which that figure was taken as the type of the present species.

 Pfichyf/onia hojipferi (!), Druce, in Bin!. C'cnii: Aiiier., Lep. Ret. i. p. 4. n. 2 (1881) (partim). 



c? 9 . Apex of forewing truncate or sinuate, distal margin angnlate at R-, 

 concave between SC'' and R- ; clayish patch near the sinus not distinct ; submedian 

 and discal blackish band merged together, the median interspace between thera 

 marked behind as an olive-russet patch, this patch sometimes vestigial. Bands of 

 hindwing rose-pink, a third band vestigial, crossing apex of cell, the black median 

 band a little more proximal than in suhhamata. 



6. Tenth tergite (PI. XLIV. f. 13) somewhat carinate above before middle, 

 apex pointed, shortly hooked ; sternite gradually narrowed to end, this rounded, 

 feebly curved npwards. Clasper (PI. XLVll. f 9) largo, somewhat acuminate ; 

 harpe curving npwards, then produced into a short, lilunt, almost horizimtal ])rocess. 

 Process of penis-sheath (PI. Llll. f. 28) rather long, slender, twisted, ending in 

 two fine points.
