This genus was first proposed by Mr. Swainson for 

 the reception of a remarkable insect from Siam and 

 Java, to which various situations had been assigned 

 by different naturalists. In external aspect it has all 

 the appearance of an Erycina y but, on examining 

 the disposition of the nervures of the wings, the 

 form of the palpi and antennae, together with the 

 structure of the feet, which are all complete in both 

 sexes, its close affinity to the true Papiliones becomes 

 apparent. The head and body are very thick; 

 abdomen short ; eyes large and salient ; palpi very 

 short, the articulations very indistinct ; antennas 

 rather long, thickening at the extremity into a club 

 which is slightly curved upwards. The anterior 

 wings are nearly hyaline, and have the discoidal cell 

 closed ; the posterior folded longitudinally, and each 

 drawn out into a very long tail curved at the extre- 

 mity. The expansion of the wings, in the only 

 known species, is about an inch and a half; the 

 inner half of the superior pair black, traversed in 

 the middle by a pretty broad green band ; the exte- 

 rior portion, consisting of a large triangular space, 

 transparent, with the nervures and external border
