OPSIPHANES. 129 
having the base of the primaries and the whole of the secondaries, except the outer 
margin, deep rufous; the female, too, has a white instead of a fulvous band. 
O. quirinus appears to be more abundant in the southern part of Central America 
than in Guatemala, whence we have received only a single specimen. 
7. Opsiphanes amphirhoe. 
Brassolis amphirhoe, Hibn. Samml. ex. Schm. ii. t. 67 '. 
Alis nigricanti-fuscis, anticis fascia arcuata fulva a costa ad angulum analem interdum integra interdum 
interrupta, maculis tribus albis apud angulum apicalem ; posticis valde elongatis et margine apud angulum 
apicalem fulvo notato; subtus fere ut in aliis speciebus hujus generis, sed maculis omnibus bene definitis. 
Hab. Guatemata, Mirandilla (Champion).—S.E. Braziu. 
A single example of this Opsiphanes sent us by Mr. Champion agrees accurately with 
South-Brazilian specimens. The appearance of this Brazilian species in Central 
America is a singular fact—the more so, seeing that it has never been noticed in the 
intermediate region. 
Some confusion has prevailed respecting this species, the name 0. amphirhoe having 
been placed as a synonym of 0. xanthus (Linn.); but with that insect, as we have already 
shown, it has no near relationship. It agrees in structure with the more typical 
members of the genus, O. xanthus with its allies forming a somewhat abnormal 
section. 
c. Body comparatively slender; pencil of hair on the secondaries as in Section 8. 
8. Opsiphanes orgetorix. 
Opsiphanes orgetoriz, Hew. Ent. Monthl. Mag. vi. p.177'; Ex. Butt., Opsiphanes, t. 1. ff. 1, 2”. 
Alis obscure brunneis ; anticis falcatis, fascia arcuata a costa ad angulum analem fulva, maculis tribus apicalibus 
albis; posticarum margine externo fulvo; subtus alis brunneis, brunneo et albo irroratis, fascia communi 
obscura per ocellos posticarum ad costam anticarum mediam extensa, anticarum margine externo gilvo 
lineis duabus valde sinuatis notato, anticis ocello unico ad apicem, posticis duobus magnis, uno mediam 
costam attingente, altero ad angulum analem ornatis. 
2 mari similis, sed fascia anticarum multo rectiore et violaceo tincta, margine quoque posticarum fulvo multo 
latiore distinguenda. 
Hab. Nicaracua, Chontales (Belt!*); Panama, Chiriqui and Veraguas (Arcé). 
This beautiful species was discovered by the late Mr. Thomas Belt at Chontales in 
Nicaragua; and his specimens were described by Hewitson!, and the female figured in 
‘Exotic Butterflies’?. Since then several specimens have been sent from Chiriqui and 
elsewhere in the State of Panama; but we have no tidings of it from Costa Rica, though 
doubtless it also occurs there. 
In the rounded form of the secondary wings and in the more slender body this species 
resembles O. xanthus, Linn., and its allies, rather than the stout-bodied species which 
we have placed before it; but the arrangement of the pencils of hair on the secondaries
