G. clorinde Godt. (= swainsonia Swains., godarti Pertij, maerula Hbn.) ('24g) is distributed from Mexico r-lorindr. 

 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 stria tion and an inconspicuous reddish miHlian spot on each wing.

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

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

22. Genus: Krieog'onia Ileuh. 



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

 the Antilles. Apart from the much smaller size and the shape of the wings the only difference from (hnep- 

 teryx 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 (i<idt. occurs from Texas and California to Venezuela. The upper surface is white, the proximal ///s»/f. 

 part of the hindwing suffused with yellowish, the liasal part of l)oth 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. —

 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 hjside; a quite similar specimen from Cuba is before me. 



23. Genus: Teriocolias Bob. 



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

 to this than to Colia.s. 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 Erycinids, and also in the 

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

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

 Terias never occur.
