 ochre-yellow. In addition to the 3 transverse lines of the forewing a further transverse line is also present 

 near the base. A small eye-spot in cellule 2 and above it two white dots. Prom Haiti. Also occurring

 of hysius which differs above in having a small ochre-yellow spot placed at the anal angle of the hindwing. 

 On the under surface the yellow transverse line before the e^'e-spot of the forewing only extends to vein 2. 

 The two brown transverse lines before and in the middle of the hindwing are distally distinctly bordered 

 with white, the two brown submarginal lines terminate at the anal angle in a black spot and the space 

 between them is filled up with white in the posterior part of the wing. The eye-spot of the hindwing is also 

 somewhat larger than in kysiu-s. From Haiti. 



33. Genus : Siteroiua Westw. 



A genus easy to recognize by the shape of the wings. The distal margin of the forewing is weakly, 

 that of the hindwing between the veins strongly excised. Below the apex of the forewing the distal margin 

 projects obtusely. Tlie mner margin of the hindwing is deeply excised before the inner angle, so that the angle 

 itseK is produced into a lobe. The costal margin of the hindwing is likewise deeply excised in the middle and 

 then forms at ^^ of its length a broad, rounded tooth, which is covered by the inner margin of the forewing. 

 The costal and median of the forewmg are strongly, the subm.edian somewhat less strongly inflated at the 

 base. One subcostal vein arises before the end of the cell of the forewing. The (J has on the forewing a vel- 

 vety scent -scale spot. The butterfhes occur in the high mountains of tropical America.

 scale spot in the middle of the forewing. Beneath the forewing is glossy copper-brown, at the apex marbled 

 with dark broAvn. The whole hindwing similarly marbled. At the costa of the hindwing is placed a silvery 

 spot, in the middle another and before the distal margin a row of ochre-yellow dots. From Bolivia and Peru. 



S. bega Westw. Similar to the preceding species, but the wings are shorter, the form consequently hcga. 

 more compact. Above dark brown. Beneath the forewing is lighter, unicolorous brown, only the apex is irro- 

 rated with black and white. Hindwing marbled with light and dark brown, sprinkled with silvery white dots 

 and spots. From Venezuela, Colombia and Bolivia. — andensis Fldr. (51 g) is a form of hega in which the 2 ande->isis.

 side of the hindwing abnost entirely absent. Only a silvery dot in cellule 2 and a small silvery angled mark 

 in cellule 3 persist. The tooth at the costal margin of the hindwing is as in the other forms. From Yungas 

 de la Paz, 1000 m. (Bolivia). 



S. zibia Btlr. Above brown with dark margin, distal area of the hindwing reddish, dusted with white ziUa. 

 at the anal angle. Beneath the forewing is lighter, with a yellow streak before the apex, the costa marbled 

 ■with yellow and brown. Hind-ndng black, marbled with brown and rust-colour, the apical area ochreous with 2 

 rust-coloured spots, a silver spot before the apex and the spots at the costa as in bega, two black spots with 

 silver^- margins before the distal margin. Expanse 42 mm. From Venezuela. 



34. Genus : Pseiidostcroma gen. nov. 



This new genus forms a transition between Steroma and 8teretnnia. As in the latter it lacks the broad, 

 obtuse tooth which Steroma has at % of the costal margin on the hindwing, but the other teeth, at the 

 distal margin, project quite as far as in the latter genus. The first tooth is somewhat stronger than' the rest 

 and forms almost a right angle at the apex. The inner margin of the hindwing is quite as strongly excised 

 as in Steroma and the distal margin of the forewing forms the same obtuse angle below the apex. The scent- 

 scale spot is likewise mostly present. 



P. pronophila Fldr. (Steroma p.) (51 g). Above brown, the distal margin and the scent-scale spot pronophila. 

 beyond the median of the forewing darker; the tips of the fringes between the veins whitish. Beneath the fore- 

 wing yello^rish brown, apex of the forewing and the whole hindwing marbled with dark brown. The latter 

 with a white spot at the costal margin, a row of 6 white dots before the distal margin and a light brown 

 spot at the anal angle. The $ is marked like the ^ except that the scent-scale spot is absent. Colombia
