72 RHOPALOCERA. 
is the comparative length of the femur and coxa in the front leg of the male. In 
Tisiphone the femur is considerably longer than the coxa, whilst in the other genera 
the reverse is the case. In Tisiphone, too, the tegumen bears a single central 
spine; in Zaygetis and Huptychia there is also a lateral spine on either side. 
The front scales on the palpi of Zistphone are shorter and more thick-set than usual 
in Satyrine. 
Two species have been described of this genus, one of which, 7. maculata, has a 
wide range, extending from Mexico to Bolivia. The range of the other, 7. hercyna, 
is hardly satisfactorily known; but it appears to be found in the same countries as 
7. maculata, though it is doubtless much rarer.

Alis fusco-brunneis, anticis parte apicali nigricante, macula subapicali maculisque septem (secunda et tertia 
conjunctis) linea curvata dispositis a margine costali ad angulum analem; posticis paulo dentatis et 
lineis duabus obscuris submarginalibus notatis: subtus anticarum basi pallidiore, apice variegato et ocello 
parvo notato; posticis purpureo tinctis et valde variegatis, lineis obscuris undulatis et serie ocellorum 
sex ornatis, quorum duo cost proximi et unus in angulo anali medius, nigris albo pupillatis.

This is a wide-ranging species, of which we have many examples from all parts of 
Central America. These all belong to the insect described by Hopffer under this name 
as distinct from 7. hercyna, which has the spots of the anterior wings larger, more con- 
fluent, and arranged in a more regular curve. In Guatemala it is not common; our 
specimens were taken in the low-lying country on both sides of the mountains, at an 
elevation of about 1000 feet above the sea.
