ATHYETIS. By E. Haensch. 121 



encloses at the end of the cell only a smaller dark spot and terminates at the distal margin in a more spear- 

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

 pseudethra Bilr. (3"2d), wliich is distinguished by the characteristic yellow longitudinal band of the hindwing pseudeihra. 

 and has already been mentioned under Lycorea halia. — I have described as assimilis Hsch. the form of pseudo- assimilis. 

 nyma without yellow colouring, in which it resembles melanina and briinnea. 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 form. 7i.ov. I designate yet another form of fseudonyma with very broad yellow oblique lalejlava. 

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

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

 form comes from Santa Cruz in South Bolivia.

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

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

 form with normal Lycorea-habitus and separated bands is mopsa F. In this the macular band of the hind- mopsa. 

 wing is narrowed towards the inner margin; ground-colour red-brown. It occurs in Guiana and on the Lower 

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

 by GoDAKT megara (= flavescens Kirhy). — According to Guppy the larva of this form is black with white dots megara. 

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

 are similar to those of Lycorea 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 description it approximates to the following cuparina. 

 species {furia), as the yellow oblique band of the forewing is said to terminate 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 Sigr. This large species resembles Jiippoi/tow.s. It occurs also in Central America (San salvadoris. 

 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 furia. 

 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 Godni. & Salv. the oblique bands of the forewing furina. 

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

 occurring in western Ecuador and South Bolivia as well as in Colombia and Venezuela. — flacilla Godni. <& Salv., flacilla. 

 from the Cauca Valley in Colombia, differs from the preceding in having 3 yellow spots at the apex of the hind- 

 wing, which are margined with black; also the base of the forewing is more broadly blackish and the brownish 

 basal streak-spots are correspondingly smaller. 



10. Genus: Athyrtis Fldr. 



In size and markings the species of this genus are very similar to those of Melinaea, but are distinguished 

 at once by the shorter antennae and the angled lower discocellular of the hindwing. (In the figure of Ath. mecha- 

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



The few forms of this genus are all very rare and occur only on the eastern slopes of the Andes from 

 Colombia to Peru. 



A. mechanitis Fldr. (33 a) has the markings almost as in Mechanitis doryssus, but is considerably larger mechanitis. 

 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 small white marginal dots. — ^In 

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

 bands of the forewing are smaller. — In salvini Srnka, from eastern Peru, the red-brown colour is duller and saltini. 

 extends on the forewing beyond the discocellular. Apex and distal margin are black-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 5 — 6 black spots and narrow, dark distal margin. — In a local form from the Upper Amazon, which I call 

 amanga form, nov., the whole apical half of the forewing is black-brown. In this is placed in addition to the amanga. 

 yellowish, very narrow subapical band 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.
