costal of the hindwing is conspicuous by its colouring. The 5 differs in the orange-yellow spot being somewhat 

 lighter and has also more blackish spots at the distal margin of the hindwing. Specimens in which the orange- j-^^ 



vellow spot is entirely absent are rare : ab. thetis form. nov. — Feuhstorper has based the subspecies metioche ihelis. 

 on 2 specimens from Colombia; it is said to be characterised by darker, deeper and more uniform yellow ground- 

 colour, longer and narrower wings, larger size, larger, lighter and more divided median spots on the under 

 surface. 



G. clorinde GoAt. (= swainsonia Swains., godarti Perty, maerula Hhi.) (24g) is distributed from Mexico clorinde. g^/ 

 to Paraguay, extremely variable in size, has the upper surface white with a faint greenish tinge, the large median 

 spot is either orange- or sulphur-yellow, on each wing is a small black median spot margined with red-yellow. - 

 The under surface is greenish with white striation and an inconspicuous reddish median spot on each wing. 

 The differs in having the 3-ellow median spot much less developed and the median spots larger and much , 



more broadly surrounded with red-yellow. — nivifera Fruhst., from Central America, is said to be distinguished nivifera. ' ^^

G. maerula .F. (24g) is distributed from Mexico to South Peru, but appears to be wanting in the east maerula. ^yv'* 

 of the district. The upper surface is lemon-yellow and has no markings except the black-brown median spot 

 and perhaps a few black marginal dots. The scent-organ on the hindwing is lighter. The under surface is green- 

 ish -with light striation and a white, reddish-bordered median spot on each wing; the subcostal of the hindwing 

 is distinctly prominent. The ?$ are mostly whitish and have a larger orange-yellow median spot on the hind- ,-j^ 



wing. A canary -yellow $-form is more rare: ab. flava jorm. nov. — To lacordairei Bdv. (= ecclipsis Cr.) belong ,^'^*'^'5'- '■ .^fff

22. Genus: Kricogoiiia Beal. 



This genus has its area of distribution from southern North America to Venezuela and also occurs on 

 the Antilles. Af)art from the much smaller size and the shape of the wings the only difference from Gonef- 

 ieryx is that the long palpi extend far beyond the head. There is no difference in the neuration. The early 

 stages are still unknown. 



K. lyside Godt. occurs from Texas and California to Venezuela. The upper surface is white, the proximal lyside. ^y< 

 part of the hindwing suffused with yellowish, the basal part of both wings yellow, the under surface slightly 

 yellow except for the almost white posterior part of the forewing, with no markings, only occasionally a black 

 median spot on the hindwing. The $ has less yellow at the base and the apex of the forewing is darker. — .y. 



terissa Luc. (= lyside Hbn.) is an aberration which is distinguished by a small black stripe at the costal margin terissa. ' ^ 

 of the hindwing. — xanthophila form. nou. (26d), from CTuatemala, is an entirely yellow form (only in the ie-jcanUiophilar'^:^ 

 male?). The underside of the hindwing is light, contrasting with the forewing. — castalia F. is the form from casialia. ^■iM 

 Jamaica. It has at the base only traces of yellow, and the under surface, especially of the forewing, is 

 even less yellow. 



K. fantasia Bilr. (26d), from Nicaragua, has in the female greenish white upper surface, at the costal fanlasia. Sv 

 margin of the forewing a dark sulphur-yellow basal stripe and light brown apical and distal-marginal markings, 

 the hindwing is light sulphur-yellow. The underside of the forewing is glossy sulphur-yellow on the basal half, 

 the rest of the wing is light sulphur-yellow, hindwing as above, in the basal half darker sulphur-yellow. Is 

 probably only another aberration of lyside; a quite similar specimen from Cuba is before me. 



23. GeniLs: Teriocolias Boh. 



It is not practicable to allow atinas Hew. to remain in the genus Terias as it is much less closely allied 

 to this than to C alias. It differs from the latter in that the fourth subcostal vein does not run into the distal 

 margin but direct into the apex and that the lower discocellular of the forewing is wanting; the lower radial 

 arises direct from the subcostal. A fourth peculiarity of this genus is the clothing of the basal half of the 

 antennae with long, hair-like, moderately appressed scales, so that the antenna when only a little magnified 

 gives the impression of a Heterocerous antenna. Similar structures occur among the Brycinids, and also in the 

 American Gonepteryx and Catopsilia, hnt not, so far as I can ascertain, in Terias. Biological reasons are also 

 against its near relationship to Terias: that is to say, atinas flies in the high mountains, where species of 

 Terias never occur. 



T. atinas Hew. (26d), from Bolivia, is above .deep sulphur-yellow with a small black spot at the disco- atinas. ^y* 



cellulars of the forewing, the basal part of both wings is black, at the distal and costal margin of the forewing 



near the apex are placed small dark spots or dots. The under surface of the forewing is sulphur-yellciw with 



reddish distal margin and small dark marginal spots as well as two black dots at the discocellulars, the under
