230 XYMPIIALirU-:. 



Anterior Legs of the male clothed with scales, and, especially the tarsus, with long delicate hairs. 

 Femur nearly cylindric. Tibia scarcely so long as the femur, cylindric, slightly curved, 

 truncate obliquely at the apex. Tarsus about the same length as the tibia, subcylindric, 

 pointed. Anterior Legs of the female longer than those of the male, slender, scaly. Femur 

 cylindric. Tibia cylindric, slightly curved, truncate at the apex, scarcely so long as the femur. 

 Tarsus shorter than the tibia. First joint one half longer than the rest combined, nearly 

 cylindric, but rather thickened towards the apex, where it is armed, as are the three following joints, 

 with two spines ; second, third, and fourth joints transverse, nearly equal ; fifth joint rather 

 longer than the preceding, tapering towards the apex, which is mucronate ; its sides furnished 

 with two tufts of seta?. 



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

 to, the tibia?. Tibiae of the middle pair armed with a few scattered spines, of the posterior pair 

 with two interno-lateral series of spines very wide apart ; the spurs short. Tarsi of the middle 

 pair shorter than the tibia? of the posterior pair, equal to the tibia? ; all the joints, except the 

 fifth, very spiny below ; the spines forming four series ; the two lateral series very regular, the 

 two inner ones less so. First joint rather longer than the rest combined ; second joint scarcely 

 longer than the third, about one third the length of the first ; fourth joint about two thirds the 

 length of the second ; fifth joint about the length of the second, with only a few slight spines 

 below towards the sides, its apex produced above. Claws curved, grooved below. Outer and 

 inner lacinia? of the paronychia scarcely differing in length, strap-shaped, hairy. Pulvillus 

 nearly as long as the claw ; the second joint broad. 

 Abdomen rather slender, not exceeding two thirds the length of the inner margin of the posterior wings. 



Larva and Pita unknown. 



This genus, like the last, consists, ;it present, of but one described species ; an insignificant insect in appearance, of 

 an almost uniform dark brown above, and of a more ochreous brown below, with a few ferruginous brown markings: 

 but in structure it is very interesting, and, to a certain extent, anomalous. From all the neighbouring genera it 

 differs in the neuration of the anterior wings, one of the subcostal nervules, probably the first, being wanting; a 

 structure more common in the group composing the families having braced, than in those which have suspended, pupae. 



Though in most points of structure this insect resembles the genera near which I have placed it, vet I am by no 

 means sure that, if ever the larva be known, it will not be necessary very materially to change its position. In the 

 mean time I have placed it near to those genera with which it has most points of resemblance, though it rather 

 interrupts the natural order of succession. 



This insect appears to be peculiar to Guiana and the valley of the Amazons.
