encloses at the end of the cell only a, sniallfr (larlc spot and terniinates at the distal margin in a more spear- 

 shaped point. This species occurs in Iktlivia, Paraguay and Argentina. — In sinithern Brazil occurs the similar 

 pseudethra Btlr. (32 d), which is distinguished by the characteristic yellow longitudinal band of the hindwing pfipudplhra. 

 and has already been mentioned under Li/corea Jialia. — I have described as assimilis Hsch. the form of pseudo- a>isiinUis. 

 riyma without yellow colouring, in which it resembles mclanliKi and bi-inuicn. Assimilis is, however, easy to 

 recognise by the 3 isolated spots in the disc of the hindwing. It occurs, like the similar forms, on the Upper 

 Amazon. — As lateflava fonn. nor. I designate yet another form of lyseudonijnia with very broad yellow oblique hilrjUini. 

 band on the forewing; this band is suddenly narrowed to a small, munded point close to the distal margin. 

 In it are placed in addition to the spot at the end of the cell 2 small (Uirk dots before the distal margin. This 

 form comes from Santa L'ruz in Soutli Bolivia. 



H. harmonia Cr. (32 d). In the tyiiical specimens of this species from Guiana the dark longitudinal band linniioiiiii. 

 of the hindwing is confluent with the dark distal margin into a large patch, as in Lijcorea ceres and many 

 Ithomiids. The forewing is pointed, especially in the 3". The yellow oblique band ends in three points. — The 

 foi'm with normal L?/corea-habitus and separated Ijands is mopsa F. In this the macular band of the hind- vmiixa. 

 wing is narrowed towards the inner nuirgin: ground-colour red-ln'own. It occurs in Guiana and on the Lower 

 Amazon. — A local form with light yellow-brown ground-colour from the Antilles and Trinidad has been called 

 by GoDART megara (= flavescens A'/r/;//). — According to Guppy the larva of this furm is black with white dots wcgnni. 

 and 2 long, immoveable, antenna-like aitpendages on the 2. segment. It feeds by day on Echites sp. The eggs 

 are similar to those of Lijcorea ceres, yellowish with numerous impressions, and are laid singly on the under- 

 side of leaves. 



H. cuparina Bates in unknown to me. According to the descrii>tion it approximates to the following cupariiui. 

 species {furia), as the yellow obli(iue band of the forewing is said to ternhnate obtusely. Bates compares it with 

 the common form from the Amazon and says that it is only to be found at the southern tributary of the Middle 

 Amazon, the Tapajos. 



In the following forms the longitudinal band of the hindwing is still more distinctly pointed proximally. 



H. salvadoris Stgr. This large species resembles hippoihous. It occurs also in Central America (San salradoris. 

 Salvador, Honduras), but has lighter, yellow-brown ground-colour and larger yellow spots. It approaches the 

 following forms in the keel-shaped band of the hindwing. 



H. furia Stgr. (32 d) may be distinguished from the similar species by the yellow oblique band of the Inria. 

 forewing, which terminates obtusely at the distal margin, and by the proximally pointed longitudinal band of 

 the hindwing. It flies in Venezuela and Colombia. — In furina Godm. d- Salr. the (jljlique bands of tlie forewing juriiui. 

 are broken up into small yellowish spots. It is commoner and more widely distributed than the typical jurui, 

 occurring in western Ecuador and South Bolivia as well as in Colomljia and Venezuela. — flacilla Godm. d- Sub:.. flurHln. 

 from the t'auca Valley in Colombia, differs from the preceding in having o ydlow spots at the apex of the hind- 

 wing, which are margined with black; also the Ijase of the forewing is more broadly l.ilackisli and the l)rownish 

 basal streak-spots are correspondingly smaller. 



10. Genus: Atliyi'fis FIdr. 



In size and markings the species of this genus are very similar to tliose of Mehnaca. but are distinguished 

 at once by tlie shorter antennae and the angled lower discoeelluhir of tlii' hindwing. (In the figure of Ath. mcclia- 

 nitis, pi. 33 a, the neuration is indistinct). 



The few forms of this genus are all ver}- rare and occur only on tlie eastern slopes of the Andes from 

 Colombia to Peru. 



A. mechanitis FMr. (33a) has the markings almost as in Mechunilis donjssus, but is consideralily larger mn-luiiiilis. 

 and may be recognised by the angled lower discocellular of the hindwing. The base of the forewing and the hind- 

 wing are red-brown; the former with blackish apical half and 3 yellow macular bands, the latter with yellow 

 and black macular band, as well as dark distal margin. Both wings with snuill white marginal dots. — In 

 the local from oberthueri Srnka, from Ecuador, the yellow longitudinal band of the hindwing is absent, and the obertliucri. 

 bands of the forewing are smaUer. — In salvini Srnku. from eastern Peru, the retl-brown colour is duller and salvi)ii. 

 extends on the forewing beyond the discocellular. Apex and distal margin are ljla(d;-brown with yellowish suba- 

 pical band. At the end and again in the middle of the cell there is a black spot. The hindwing has a central row 

 of .'-j—fi black spots and narrow, dark distal margin. — In a local form from the Upper Amazon, which I caU 

 amanga form, nor., the whole apical half of the forewing is lilack-brown. In this is placed in addition to the iniuDiga. 

 yellowish, very narrow subapical l)and a brownish band near the end of the cell. Of the two black spots in 

 salvini the distal one is suppressed in the dark apical half.
