distant. Posterior wings : apex acute ; apical margin concave. Ab- 

 domen slender, and tufted in the tf , rather stouter in the $ . 



The only species in this genus is of doubtful location. By 

 the late J. F. Stephens, in his Museum Catalogue, it is included 

 amongiheLithoyraphia (doubtless from its superficial resemblance 

 to Lithographia campoliliana) ; but not possessing the folded 

 costa, it can no longer remain there. It certainly comes nearer to 

 EupoBcilia as to appearance, especially to the Section B. of that 

 group (vide infra) ; but its admission into that genus can scarcely 

 be warranted. In structural details there appears sufficient to 

 justify its figuring as a distinct genus, and consequently the 

 name Calosetia is proposed for it. 



1. nigromaculana, Haw. Alis anticis niveis; costa nigro ferrugi- 

 neoque punctata, apice puncto ferrugineo ; margine dorsali maculis 

 nigris ; ad angulum analem macula ocellari plumbea atomisque 

 lineolis longitudinalibus atris ; posticis basi griseis, apice fuscis.

Head snow-white, with a few dusky scales close over the eyes. 

 Face snow-white. Eyes black. Palpi snow-white. Antennae fus- 

 cous, alternated with drab. Thorax black in front, snow-white 

 behind, sometimes with a spot on the vertex white. Patagia black 

 at the base, the remainder white. Anterior wings white, with black 

 fuscous and ferruginous markings. At the base are a number of 

 black spots, with a patch of confluent streaks (also black) situated 

 before the middle of the dorsal margin ; these spots and patch, taken 

 together, form the rhomboid basal mark. Within the anal angle is 

 an elongated, acute, triangular mark, black and speckled at the base, 

 ferruginous at the apex. The costa is maculated with black to 

 the middle, where is an oblique quadrate mark, usually fuscous, 

 followed by smaller markings, more or less distinct, and becoming 

 ferruginous as they approach the apex, where is an eye -like spot of 

 the latter colour ; the subapical marks produced and confluent ; the 

 middle of the dorsal margin with black spots, or streaks of black, 

 varying in intensity and in number from two to five ; the central 

 part of the wing more or less marked or spotted with fuscous. Near 

 the apex is a broad black, longitudinal, and somewhat curved streak, 

 and below it is the ocelloid patch, consisting of two enclosed lustrous 

 leaden clouds, sometimes freckled with black, with a dusky mark 

 between, bearing the longitudinal black streaks ; the apical margin 

 of the wing marked with ferruginous or fuscous. Apical scales black, 

 with white bases and tips. Cilia : at the apex deep ferruginous, 

 then becoming paler, with white bases, midway before the anal 

 angle, then mottled grey, with white tips, becoming white at the 

 anal angle, and iron-grey beyond it. Posterior wings shining, 

 clothed with coarse fuscous scales, especially towards the apex, on a
