374 BHOPALOCEEA. 



have a long porrect terminal joint, and the first segment of the subcostal nervure of 

 the secondaries is shorter in proportion to the second segment than is the case in 

 Pellicia. 



On the whole the two genera seem fairly distinct, though Pellicia costimacula is 

 somewhat intermediate between the two. 



Mr. Watson recognizes two named species of Mycteris, of which M. ccerulea is the 

 type of the genus, the other being Arteurotia cambyses, Hewitson. 



1. Mycteris caerulea. (Tab. LXXXIIL figg. 31, 32, 33 s .) 



Mycteris cmrulea, Mab. Pet. Nouv. Ent. ii. p. 114 (1877) x ; Wats. P. Z. S. 1893, p. 56 2 . 



Alis fusco-nigricantibus fere unicoloribus, posticis ad marginem costalem vix pallidioribus : subtus pallidioribus ; 



anticis ad marginem internum lilacino-griseis ; posticis dimidio distali viridi-cseruleo ; palpis et abdomine 



subtus fuscis. 

 2 mari similis, alis supra indistincte fasciatis : subtus pallidioribus, colore caeruleo posticarum magis obscuro. 



Hob. Guatemala, Polochic Valley (F. B. G. & 0. S.) ; Nicaragua, Chontales 

 (Janson). — Colombia 1 . 



M. Mabille described this distinct species from a specimen from Colombia, whence 

 we also have a male example agreeing with another taken by ourselves in Guatemala. 

 Our only female is from Nicaragua ; but this appears to have traces of bands on the 

 wings, but from its poor condition they cannot be traced satisfactorily. 



The male genitalia, like those of Pellicia, have unsymmetrical cleft harpes ; both 

 portions have serrate ends : the lower lobe of the right harpe is upturned and overlaps 

 the upper lobe, which has a large terminal patch of strong papilla?; the lower lobe of 

 the left harpe also overlaps the upper lobe, which, however, is much simpler and 

 narrower. (See Tab. LXXXIIL fig. 33.) 



b. Antenna? with a long terminal slender end, this portion being as long as the 

 slightly swollen club and in an even curve with it (except in Antigonus). 



NISONIADES (%). 

 Nisoniades, Hiibner, Verz. bek. Schmett. p. 108 (1816) ?; Wats. P. Z. S. 1893, p. 51. 



Papilw bromius, Stoll, is the type of this genus of Hiibner. Mr. Watson drew 

 his characters from specimens in the British Museum identified as belonging to Stoll's 

 species. We have two similar specimens before us, but we doubt the "correctness of 

 the names of the Museum examples. Stoll's figure omits the characteristic black spot 

 with its two white dots at the end. of the cell of the primaries. It follows that though 

 we know Mr. Watson's genus Nisoniades we cannot be certain that it is Hubner's 

 based upon Stoll's P. bromius. *
