apex, which is pointed, showing faint indications of two articulations beyond the middle. 

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

 cylindric, rather thickened towards the base, longer than the tibia. Tibia subcylindric, curved. 

 Tarsus two thirds the length of the tibia, five-jointed. First joint nearly cylindric, unarmed, 

 more than double the length of the rest combined ; second joint about one sixth the length of 

 the first, armed at the apex, as are the two following joints, with a long stout spine on each side ; 

 third joint shorter than the second, transverse ; fourth joint transverse, shorter than the third, 

 obliquely truncate, so that the lower surface is but about half the width of the upper ; fifth joint 

 as long, but scarcely so broad, as the second, rounded, armed with some rather strong seta?. 

 Middle and Posterior Legs rather long ; the femora of the former longer than, of the latter equal in 

 length to, the tibia?. Tibia? of the middle pair spiny internally ; the spines placed in two rows ; 

 spurs stout. Tarsi spiny below and laterally ; the spines rather long, arranged in four series, 

 except on the fifth joint which has only two series. First joint four times the length of the 

 second ; third joint rather more ; fourth joint rather less than half the length of the second ; fifth 

 joint equal to the second. Tibia? of the posterior pair smooth, cylindric, unarmed, except by the 

 two ordinary spurs, which are rather shorter than usual. Tarsi longer than the tibia?, cylindric, 

 the lower surface not flattened, spiny laterally and below ; the spines somewhat arranged in four 

 series ; the fifth joint less spiny. First joint three times the length of the second ; third joint 

 about half the length of the second, and double that of the fourth ; fifth joint two thirds the 

 length of the second. Claws, in both pairs, curved, grooved, rather slender. Outer paronychia 

 very slender, linear, as long as the claw. Inner paronychia short, broad. Pulvillus two-jointed, 

 shorter than the claws. 

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



Larva and Pupa unknown. 



Ectima has the smooth eyes of Myscelia, and the neuration of Cybdelis. It differs from botli in its antenna? and in 

 the dissimilar structure of the middle and posterior tibia? and tarsi. 



Only one species of the genus is as yet described. This is an insect of rather small size, of a fuscous ash colour 

 above, with some blackish lines ; the anterior wings crossed by a broad white band, and the posterior wings marked 

 with some ocelli near the margin. The lower surface inclines to ochreous. Another species, of which an imperfect 

 specimen exists in the British Museum, differing in the position and form of the band, and having a blue gloss on the 

 posterior wings above, will be figured in one of the supplementary plates. 



We know nothing of the habits or of the earlier stages of these insects, which seem to be nearly confined to Brazil 

 and Guiana, and the north of South America.
