" Body, robust, thickly clotlied with soft woolly haiis, rather small in size, and of dark 

 colours ; the 7vi)igs with spots of orange, or dirty white, but not ocellated ; head, small , 

 strongly tufted in front ; eyes, prominent, naked ; palpi, extraordinarily elongated, being one 

 third, or even in some species half, the length of the whole body ; porrected horizontally, not 

 compressed, thickly clothed with hairs of modei'ate length, the inner edges uniting together) 

 so as to form conjointly a long conical beak, obtuse at the tip ; second joint oval ; third 

 joint greatly elongated and slender ; antennce, not nearly half the length of the forewing, 

 straight, articulations indistinct, gradually thickening from the base to the tip, which is obtuse i 

 thorax, oval, hairy ; tippets strongly developed ; abdomen, small, slender. Forewing, of 

 moderate size ; costal margin moderately arched, apex acute, outer margin strongly angulated 

 below the apex, the lower discoidal nervule extending into the most prominent part of the 

 angle, about five-sixths of the length of the costa, inner margin straight, one-fourth longer 

 than the outer margin. None of the veins dilated at the base. Costal nervnre extending to 

 about half the length of the costa ; sidtcostal nervure with the first and second branches free' 

 arising before the anterior extremity of the discoidal cell, third branch arising far beyond the 

 cell, followed at a short distance by the fourth, which extends to the tip of the wing ; upper 

 r//i-(-tf-a7////rt;- «^;zv//^ minute and sub-oblique, w/^/i//^ and lozver disco-cellulars of nearly equal 

 length, very slender, and uniting into a curve, closing the discoidal cell about the middle of 

 the wing, by uniting with the third median nervule at about the same distance from its base 

 as exists between the first and second branches. Hindwing, irregularly and broadly ovate ; 

 the costal margin produced in the middle into a considerable-sized lobe, outer margin strongly 

 scalloped, abdomittal margin forming only a slight gutter for the i-eception of the abdomen > 

 prcccostal nervure short, curved outwards ; costal nervure extending to the outer edge of the lobe, 

 of which it follows the outline ; subcostal nervure arising just opposite to the proecostal, branch- 

 ing at a considerable distance from its base ; upper disco-celhdar nervide xtilOa&c ^\oxi, dXvaQ^t 

 transverse, arising at a distance from the base of the subcostal branch about equal to the space 

 between the base of the subcostal and its branch ; loiocr disco-cellular slender, but distinct, 

 more oblique than the upper disco-cellular, and slightly curved, closing the discoidal 

 cell by its union with the third median nervule at a very short distance from its origin ; 

 the third median nervule considerably cui"ved after its union with the lower disco-cellular 

 nervule. Forelegs, of the tnale small and brush-like, densely hairy, the tarsus rather 

 shorter than the tibia, cylindrical, exarticulate, and destitute of claws. Of the female 

 considerably longer than those of the male, but articulated like the middle and hind 

 feet. Tarsus armed with short spines beneath. Claim curved, dilated at the base, horny, 

 acute at the tips. Paronychia slender, membranous, bifid, finely setose ; the outer division acute, 

 the inner one shorter and more triangular. Pulvillus broadly transverse, the base narrowed- 

 MlDDLE and hindlegs, moderately elongated, thickly clothed with scales; femur hairy 

 beneath ; tibia and tarsus armed beneath with short spines ; clazos and their appendages formed 

 exactly as in the forelegs of the female." 



" Larva rather slender, subcylindrical, destitute of spines or points. Tail simple. 

 Body finely pubescent, and very delicately shagreened, with pale longitudinal stripes at 

 the sides, very closely resembling those of the Pierince, Pupa short, suspended by the 

 tail. Thorax- case rather gibbose in the middle of the back. Head-case not produced 

 into a beak." 



"The peculiar structure of the forelegs of this genus separates it from all the preceding 

 genera, being imperfect and brush-like in the males, but articulated and furnished with 

 claATS and their appendages in the females, exactly as in the tarsi of the hind feet. In 

 other respects, if the gradually clavaled straight antetince and the elongated palpi is
