yellow spots. It feeds on the leaves of a species of Piperis, but only during the night, concealing itself in the day by rolling a portion 

 of the leaf around its body, in order to protect itself from the sun, by fastening the edge of the whorl to the disc of the leaf by silken 

 threads, in the manner of the Hesperidai and Tortricid^. The Chrysalis is greyish, tinged with flesh colour, and marked with small 

 brown spots and transverse lines, and is attached by the tail to the stalk of the plant, which had previously received a coating of silk 

 round the place of attachment. 



The Perfect Insect exhibits a much less decided relation to Nymphalis ; the triangular form of the fore wings, and the very broad 

 hind ones furnished with a long tail give it a very peculiar appearance ; whilst, in the general colour of the upper surface of the 

 wings, it resembles some of the Heliconian. The complete obliteration of one of the branches of the postcostal vein of the fore wings, 

 and the junction of the first and second branches with the costal vein, are characters to be noticed, as well as the abbreviation of the 

 costal vein of the hind wings. 



Like Clytemnestra, the type and only known species of this genus is a native of Tropical America, and appears to be subject to a 

 remarkable amount of variation, according to the localities in which it is found. In the Brltisli iSIuseum Collection are several of these 

 varieties, or geograpliical subspecies. The one represented in our plate has the angle of the apical margin of the fore wings very 

 much produced, and the bar beyond the middle of the same wings formed of distinct spots. Another has the fore wings much shorter 

 than in the type; the yellow oblique bar of these wings very broad, without any subapical yellow spots. Another from Bolivia is 

 nearly similar to the last in form ; but the space from the anal angle to the tail of the hind wings is much more oblique and 

 entire, not scalloped, and the yellow bar of the fore wings is narrower. Others again, from Venezuela, hare the wings somewhat less 

 elongated than in the type, with a regular row of yellow subapical spots near the apical margin of the fore wings.

Body robust ; wings large ; fore wings more or less liooked at the tip ; hind wings furnished with a spatulate tail ; 



under side of the wings marked with silvery patches. 

 Head of moderate size, hairy, slightly tufted in front. 



Eyes prominent, naked. 



Labial Palpi nearly erect, elevated higher tlian the level of the top of the eyes, scaly ; the inside of each 

 furnished with a coating of appressed hairs ; middle joint also with a small erect tuft on the middle of the 

 upper surface ; terminal joint small, compressed, and truncate at the tip when seen from the side. 



Antennce rather short, not half the length of the fore wings, nearly straight ; terminated by a slender, elongated, 

 and gradually formed club, finely carinated beneath on the inside. Tip rather obliquely rounded off. 

 Thorax elongate-ovate; not very hirsute. 



Foi-e Wings Inrgc, subtrigonate, more or less hooked at the tip. Fore margin very much curved; apical angle 

 acute. Apical margin nearly three fourths the length of the anterior, very slightly scalloped. Inner margin 

 nearly straight, and equal in length to the apical margin. Costal vein strong, extending to three fourths of 

 the length of the costa. Postcostal vein slender; its first and second branches arising before the extremity of 

 the discoidal cell, and both running into the costal vein ; the first branch near the middle, and the second 

 nearly at the extremity of the costal ; third branch of the postcostal arising near the middle of the wing, and 

 extending nearly to the apex ; fourth branch arising at a little distance beyond the middle of the wing, and 

 extending to the tip, being curved downwards a little before it reaches the extremity of the wing ; terminal 

 part of the vein reacliing below the apex. Upper disco-cellular vein very short, oblique, arising at the length 

 of one third of the wing from the base ; middle disco-cellular obsolete ; the two discoidal veins arising together 

 at the extremity of the upper disco-cellular ; lower disco-cellular arched transversely, the curve being towards 

 the base of the wing, and uniting with the third branch of the median vein at the distance of a line from its 

 origin, closing the discoidal cell ; this third branch of the median vein very much arched.
