ACHALARUS; COGIA. By Dr. M. Draudt. 877 



A. buffumi Weeks is a species having remained unknown to me, and it seems to me very doubt- biiffumi. 

 fully placed here. Above dark brown, strewn with grey except the apex ; from the middle of the costal margin 

 across the cell-end to the proximal angle extends a series of very prominent white hyaline spots: 2 small 

 subcostal ones, in and below the cell-end one large one each, and in the angle of the median veins behuid it 

 a smaller one; 2 small subapical dots; an antemedian and a postmedian darker band, the same on the hind- 

 wing very much dusted with grey. Beneath the same, the hyaline spots more coherent, the proximal angle 

 of a lighter colour, from where a lighter pait extends to the apex parallel with the margin. Hindwing 

 with more faded bands. Expanse of wings: P/g inch. Suapure (Venezuela). 



31. Genus: Aclialariis Scdd. 



Tlie only species also has rounded hindvings, but with a very slightly produced anal-angular apex, 

 the upper median likewise rises somewhat before the cell-end. The 2 has no hair-tuft on the posterior tibiae. 

 Costal fold present. 



A. lycidas Abb. <i- Sm. (= lyciades Hbn.) (170 d). Above dark brown with sjjeckled fringes and yellow lycidas. 

 discal hyaline spots of the forewmg, the middle one being small and cjuadrangular and protruding before 

 the others towards the margin. Beneath the hindwing exhibits a white marginal area, and it is very much 

 transversely watered with black. North and Central America. 



32. Genus: Cogia Btlr. 



Well distinguished by a star-shaped hair-tuft exhibited by the c? on the upper surface of the hindwing 

 which is entirely rounded off, not produced at the angle. The posterior tibiae do not exliibit a hair-tuft, 

 the (J is without a costal fold. 



C. hassan Btlr. (170 d) is a small, above dull blackish-brown species with speckled fringes and 4 minute /ms.wn. 

 subapical spots on the forewing. Beneath the proximal margin of the forewing is reddish-yellow, the hind- 

 wing exhibits 4 whitish undulate lines and the space between the two middle ones darkened. Brazil. 



C. cajeta H.-Schdff. (170 d, e) is larger, above towards the base faintly haired olive-greenish, beside cajcta.' 

 the small apical spots with 6 small, white, discal hyaline spots partly bordered with a darker shade. The 

 hindwing exhibits 2 irregiilarly undulate macular bands. The under surface is lighter yellowish-brown, otherwise 

 marked the same, the distal macular band of the hindwing outside light. Sovith America. 



C. hippalus Edw. (= gila Plotz) (170 e) is still larger; the lowest discal spot of the forewing which is hippalus. 

 in cajeta divided into 2 small ones, is here large, outside and inside somewhat gnawed out. The under sur- 

 face of the hindwing is light ash-grey, towards the margin almost white, strewn with brownish, with 

 3 bands of brownish-grey spots. From Arizona to Mexico. 



C. calchas H.-Schdff. (= terranea Btlr.) (170 e). Here the discal spots of the forewing are absent caJchas. 

 except 1 to 3 small yellowish costal-marginal spots below each other. The hindwing is beneath brown, strewn 

 darker, with similar macular bands as in hippalus, but instead of the light marginal part there is another 

 marginal band, the median band and antemarginal band being lead-coloured, the apex of the forewing strewn 

 with a whitish grey. South America. 



C. Valeriana Plotz (= Valeria Plotz m. s.) (170 e) is midway between hippalus and calchas, with Valeriana. 

 somewhat smaller discal hyaline spots than hippalus. whilst the under surface is coloured and marked more 

 like in calchas; the basal part of the hindwing is uni-coloured dark. From Mexico. 



C. troilus Mob. is above coloured lilvc calchas, but with broader wings, with 4 small subapical spots iroilu.'!. 

 in an oblique line; fringes greyish-black. Beneath the forewing is reddish-grey in the two basal thirds, distally 

 lilac-grey, the proximal margin whitish. Hindwing light violettish-grey, with two blackish bands which are 

 very broad and only leave a narrow stripe of the ground-colour betwen them. Hair-pencil at the proximal 

 margin of the hindwing long, ash-grey, almost white. Bolivia. 



C. helenus Mah. is above very similar, with 5 small subapical spots. Fringes speckled somewhat helenus. 

 darker. Beneath the forewing is brown, at the apex light violet. Hindwing violettish-grey with two regular, 

 dentate, blackish bands. The hair-pencil at the proximal margin of the hindwing is short and of the same 

 colour as the ground of the wing. Brazil. 



C. eluina G. d- S. (170 e, f) is above dull brown with the same small sjjots as in calchas, with 2 ir- cluina. 

 regulary undulate macular transverse bands across both wings. Fringes slightly undulate and particularly 

 on the hindwing speckled somewhat darker. Beneath coloured and marked the same, the forewing somewhat 

 lighter than the hindwing. Mexico and Central America.
