ANTIRRH#A.—TISIPHONE. 71 
Hab. Panama, Chiriqui (Zahn), Bugaba (Arcé 1). 
This form, which is very closely allied to A. miltiades, differing from it chiefly in the 
absence of the discal white spot of the secondaries, appears to be restricted to Chiriqui 
and its vicinity, where it exists to the exclusion of the allied form. 
3. Antirrhea pterocopha. (Tab. VII. figg. 4, 5, 6.)

? mari similis, sed colore fusco dilutiore, anticarum fascia transversa ultra cellulam cyanea notata maculas 
albidas includente, plaga fulva posticarum multo majore et margine externo late fulvo notato, maculis pos- 
ticarum cyaneis ad marginem internum absentibus. 
Hab. Costa Rica (Endres); Panama, Santa Fé and Calobre (Arcé). 
The specimen from which our original description was taken is a male in bad 
condition, sent by our collector, Arcé, from Santa Fé; since then we have received 
others of both sexes from the same country and also from Costa Rica. In colour it 
most resembles A. philopamen, from the Upper-Amazon region; but it differs very 
considerably in the form of its anterior wings. These at their apex are abruptly 
obtuse instead of rounded, and the outer margin strongly angulated at the extremity 
of the upper radial. The great difference, too, in the size and coloration of the sexes 
is remarkable, no such contrast being seen in A. philopemen. It appears to be a 
scarce insect, as we have received but few examples of it, notwithstanding the large 
collections that have come to us from the country it inhabits. 
TISIPHONE. 
Tisiphone, Hiibner, Samml. ex. Schmett. ii. t. 86. (Type 7. hercyna, Hiibn.) 
Tisiphone, Westwood, Gen. Diurn. Lep. ii. p. 8370; Butl. Cat. Sat. B. M. p. 71. 
When first used by Hiibner* this genus included three species, none of which belongs 
to Tistphone as now understood. He afterwards added 7. hercyna; and this has long 
stood as the only representative of the genus, to the exclusion of the other three. 
According to strict law the modern practice is incorrect; but in dealing with 
Hiibnerian genera great inconvenience and confusion would arise by enforcing con- 
formity, and no doubt Tisiphone had best be left to stand as the name of this genus.
