origin of its second nervule. Discoidal nervure not extending into the cell. Third submedian 

 nervnle curved, not angularly bent. 



Anterior Legs of the male small, scaly ; femur and tibia nearly equal in length. Tarsus one-jointed, 

 less than one third the length of the tibia, fusiform, more obtuse at the base, very pointed at the 

 apex. Anterior Legs of the female rather longer and stouter than those of the male. Tarsus 

 but little shorter than the tibia, clavate, indistinctly four-jointed ; all the joints except the fourth 

 with a stout spine on each side at the apex ; the base of all, except the first, with tuft of stiff 

 hairs resting on these spines ; first joint more than four times the length of the rest combined, 

 clavate, obliquely truncate at the apex ; second and third transverse ; fourth smaller, nearly 

 quadrate. 



Middle and Posterior Legs with the tibite scarcely equal in length to the femora, spiny within, 

 the spurs strong. Tarsi about equal in length to the tibire, spiny, the spines somewhat arranged 

 in lines below and at the sides ; the first joint equal to the rest combined ; second and third 

 about of equal length ; fourth much shorter, broadest at the apex ; fifth elongate-oval, slightly 

 truncate at the apex, as long as the third and fourth combined, broader than the other joints. 

 Claws rather short, curved, grooved below. Paronychia bilaciniate ; the outer lacinia as long as 

 the claw, strap-shaped ; inner nearly triangular. Pulvillus jointed, not so long as the claw. 

 Abdomen clavate, extending but little beyond the inner margin of the wings. 



Larva and Pupa unknown. 



Its diaphanous wings with black markings give to this genus so much the external appearance of the two following 

 o-enera, that even Hiibner united them in one group. It is, however, too well marked to allow of its being 

 confounded with either Methona or Thyridia. Its short antennae, and the structure of the anterior feet in the females, 

 seem to point out an affinity to Lycorea ; but in the neuration of the posterior wings it differs remarkably from that 

 o-enus. From Methona it may be known by the structure of the anterior feet in both sexes, and by some differences 

 in the neuration of the wings. Thyridia being one of those genera which have the anterior tibite and tarsi of the 

 males reduced to a simple knob, and having a very different neuration of the posterior wings and much longer antenna;, 

 is readily distinguished from it. 



I am not quite sure that I am correct in placing Heliconia Lamyra of Latreille in this genus, having only seen one 

 specimen, and that without antenna?, I have, however, little doubt that this is its correct position, and that it forms a 

 connecting link between this and the preceding genus. 



Luna seems confined to the equatorial parts of South America.
