Q margine anticarum externo convexo, posticis paulo angulatis ; alis supra fuscis, subtus punctis parvis nigris

Hab. Panama, Chiriqui (Ribbe 1). 
The only specimens we have seen of this species are the types in Dr. Staudinger’s 
collection, which were taken at Chiriqui by Herr Ribbe, who has since informed us that 
they came to sugar placed at night for capturing Heterocera. It would thus appear 
that the great apparent rarity of all the members of this genus is probably due to their 
nocturnal habits. 
Subfam. ACRAINA*. 
ACTINOTE. 
Actinote, Hiibner, Verz. bek. Schmett. p. 27 (1816). 
Acrea, Doubleday, Gen. Diurn. Lep. p. 187 (partim). 
This section of the old genus Acre@a contains nearly fifty South-American species, 
which are distributed throughout tropical America from Southern Mexico to the 
Argentine republic, the metropolis of the genus being Ecuador and Peru. Whether 
any are found in Guiana is doubtful. Within our region four species occur, only one 
of which reaches Southern Mexico; one is peculiar to Costa Rica; and two are widely 
distributed over the country, one of which passes into the northern part of South 
America. 
Actinote may readily be recognized from the Old-World representatives of Acrea by 
the tibia of the front legs of the male being very short, and the tarsus being altogether 
absent, or only present in a single short rudimentary joint. In A. anteas the femur is 
considerably longer than the coxa; but in A. now and some of its southern allies these 
joints are nearly equal. In A. horta, which should be taken as the type of the genus 
Acrea, the tibia is comparatively long, and there is a well-developed single tarsal joint. 
In other forms, such as A. natalica, the tarsus consists of four slender joints. 
Regarding the secondary sexual male characters, Actinote does not differ materially 
from Acrea, as represented by A. horta; the tegumen is a simple slender hook, and 
the harpagones also simple, without teeth; the chitinous piece which projects back- 
wards along the ventral surface of the abdomen is very broad, and shaped somewhat 
* Doubleday, who seems to have paid considerable attention to this subfamily, divided it into six sections, 
but kept them all in the single genus Acrea. A thorough revision of these insects would, we are confident, 
fully justify their division into several genera; for not only do we find very diverse conditions in the proportion 
of the joints in the front legs of the male, but also in the size and shape of the penis and the secondary sexual 
male organs. The American members of the subfamily, so far as we have been able to examine them, seem 
fairly constant in their characters; and for them we use Hiibner’s title Actinote, and give a few of its leading 
characters under the generic heading.
