EUPTOIETA. 169 



of the females more elongate. Femur nearly cylindric, straight. Tibia shorter than the 

 femur, nearly cylindric, curved, slightly spiny externally towards the apex ; the spines sometimes 

 very minute and slender. Tarsus rather shorter than the tibia, five-jointed. First joint 

 subcylindric, slenderer at the base than at the apex, which is very obliquely truncate ; second 

 short, about as wide as long, obliquely truncate at the apex ; third still more obliquely truncate, 

 its upper surface being hardly half the length of the lower ; fourth shorter, scarcely visible from 

 above, being covered by the fifth ; all these, except the last, terminated by two stout spines, 

 covered at the base by a small tuft of delicate seta?. 

 Middle and Posterior Legs rather elongate ; the femur in the former rather shorter, in the latter 

 rather longer, than the tibia. Tibia nearly cylindric, spiny both within and without, the spines 

 near the apex being the longest ; spurs long. Tarsi longer than the tibias ; all the joints 

 cylindric, spiny ; the spines of the lower surface arranged in two closely approximating series, 

 those of the lateral series but little longer than the others. First joint not quite equal in 

 length to the rest combined ; the three following joints progressively shorter; fifth not quite 

 equal to the second and third combined. Claws long, grooved below, lobed at the base, 

 nearly straight, except at the apex, which is slightly curved. Paronychia very small, lobed at 

 the base ; the outer lacinia slender, pointed ; inner lacinia wanting. 

 Abdomen rather slender, about two thirds the length of the inner margin of the posterior wings. 



Larva elongate, each segment with two dorsal spines set with hairs. 

 Pupa elongate, ovate, but little angular, tuberculate, the head rounded. 



Of the two species on which this genus is founded, one inhabits the United States, the other Mexico and the West 

 Indian Islands, where they represent the preceding, purely Old World, genus. In the colouring of the upper surface 

 they closely resemble Atella, but below they want the pearly colouring and ocellated spots of the posterior 

 wings. 



The Larva of Euptoieta Claudia, as figured by Abbot, is cylindric, elongate, of a pale flesh-colour, with two longi- 

 tudinal white bands on each side, the upper one marked with a series of black spots ; the back has a series 

 of red spots, and each segment bears two dorsal spines set with hairs, the two on the prothoracic segment 

 being longest. Its food is said by Abbot to be the common passion-flower of the Southern States, Passiflora 

 incarnata ; but, as I have met with the insect further north than the limits of this plant, it must have some other 

 food. 



The Pupa is elongate ovate, scarcely at all angular ; the head rounded, the back tuberculate ; its colour pure silver 

 or mother of pearl, dotted with black and gold, the tubercles being gilt. 



The Perfect Insect appears in eleven days after the change to the pupa. It is an insect of rapid flight, 

 frequenting open places, especially near rivers, delighting to sit on the dry sand, rising instantly if approached, and 

 very difficult to capture, and, from its rapid and peculiar flight, very difficult to follow, even with the eye. I met 

 with it from the northern bank of the Ohio to the St. John's, East Florida.
