ANARTIA. 215 



Anterior Legs of the male clothed with small scales. Femur scarcely stouter than the tibia. Tibia 

 rather longer than the femur, stoutest at the base, where it is slightly curved. Tarsus slender, 

 subcylindric, slightly tapering to the apex, which is truncate, about half the length of the tibia. 

 Anterior Legs of the female scaly, stouter than those of the male. Femur nearly cylindric, 

 slightly curved. Tibia three fourths the length of the femur, slightly curved, scarcely, if at all 

 stouter at the base than at the apex. Tarsus about four fifths the length of the tibia, 

 five-jointed. First joint nearly thrice the length of the rest combined, subcylindric, smooth, 

 obliquely truncate at the apex, which is armed below, as is the case in the three following joints, 

 with two stout spines, covered by a sbght tuft of setae at the base of each succeeding joint ; 

 second joint less than one fifth the length of the first, about one half longer than the third, 

 which is transverse ; fourth joint very short ; fifth small, obtuse at the extremity. 

 Middle and Posterior Legs rather long. Femora of the middle pair about equal to those of the 

 posterior pair, shorter than the tibia\ Tibiae irregularly spiny externally, with two distinct 

 series of spines internally. Tarsi spiny above, below, and, except the fifth joint, laterally ; the 

 spines below arranged in two nearly regular series. Claws curved, grooved below. Paronychia 

 bilaciniate. Outer lacinia elongate, pointed, as long as the claw. Inner lacinia elongate, not 

 quite so long as the outer, pointed. Pulvillus jointed, rather narrow, not quite so long as the 

 claws. 

 Abdomen rather short and slender. 



Larva and Pupa unknown. 



Anartia differs from all the preceding genera in the peculiar neuration of the anterior wings, which, moreover, is 

 not absolutely the same in the different species. In Anartia Amathea, An. Fatima, and An. Lytraea, the first 

 subcostal nervulc is wanting ; the second, arising at the end of the cell, becomes confounded for a short distance with 

 the costal nervure, then, almost coming in contact with the third subcostal nervule, it is bent obliquely upwards, and 

 becomes atrophied just before the costa. There is a short rudimentary discoidal nervure visible in the cell, opposite the 

 anastomosis of the upper disco-cellular with the first discoidal nervule. In Anartia Iatrophse the first subcostal 

 nervule anastomoses with the costal nervure, and, after being confounded with it for a considerable distance, separates 

 from it, curves slightly downwards to be united for a time with the second subcostal nervule, then separates from this 

 to be directed towards the costa. The second subcostal nervule, after its separation from the first, just touches the 

 third subcostal, and then is directed obliquely towards the costa. This structure is analogous to what we have seen in 

 some species of Danais, and to a structure we shall find in some other genera towards the end of this family. 



It is of great importance carefully to unravel these intricacies of the neuration of the wings, as they throw a light on 

 the more complicated structure met with in some of the nocturnal Lepidoptera, and help to explain the origin of the 

 areolets, as they have been termed, which are of common occurrence in many families of the Heterocera. It will be 

 found that these areolets are very frequently formed by the anastomosis of two nervules, or of a nervure and nervulc. 

 In some of the Notodontida;, the second subcostal nervule actually turns downwards, crosses the nervure before the 

 origin of its third nervule, and from its subsequent direction might easily be mistaken for the first discoidal nervule. I 

 must not be understood to speak here of the transverse nervules which arc sometimes to be met with in the Hepiolidai 

 and other families ; these are the first appearances of the innumerable transverse nervules of the Neuroptera. 



This genus is met with throughout the whole tropical portions of America, including the West Indian Islands. 

 From the little known of its habits, it would appear that they much resemble those of the Vanessa?. All the species 

 are common in the countries where they occur, and the two species which have the widest Geographical Range are 

 subject to some slight variations in colour, apparently dependent on locality.
