684 OHIMASTRni: BAEOTIS. By Dr. A. Seitz. 



■sponsa. C. sponsa Stgr. (135 g). Similar to the preceding, but also the distal area is golden green, except 



a narrow border, a dark submarginal line and a dark large spot before the apex of the forewing. On 

 the Jurimaguas. 



57. Genus: Chiniastrum G. and S. 



The small, delicate butterflies of this genus consisting of but 2 species exhibit an alliance to the Mesene 

 and Esthemopsis, and are placed before the Symmachia by Stichel *). They differ from these two groups 

 by white wings of a sillien gloss, from the latter genus by the gently curved, not bulged-out costa of the 

 forewing. The body is more delicate than in Caria and Esthemopsis, approximating more the Baeotis. 

 argenteum. Ch. argciiteuni Bat. (= hewitsonii Bsd.) (128 b). Silky- white with a rusty- yellow base of the wings 



and a black margin. Central America, particularly on the Chiriqui; single, though not rare. 

 caniKtca. Ch. carnutes Hew. (128 6, as carmitus). Silkj^ white, from the black distal margin black tips extend 



towards the base, two of which intersect each other in the shape of an X on the forewing. Colombia, not 

 common. 



58. Genus: Baeotis Hbn. 

 Tinjr, black and j^ellow, sometimes also white and black butterflies flying about in the sunshine during 

 day-time, with a delicate body, a somewhat projecting apex of the forewuig and an extraordinarily short cell 

 of the hindwing. which is not even half as large as the cell of the forewing. About a dozen of species are 

 known. 

 fclj.r. B. felix Hew. (134f). ^^liite with a broad black border, the lemon-coloured base of both wings se- 



parated from the white ground-colour by a black stripe (from the middle of the costa of the forewing to 

 Iclkinshiui. the middle of the inner margin on the hindwing. Bolivia and Peru). — In felicissima Thm. (134 f) from Ecua- 

 dor a lustrous light-yellow line runs through the black margin. — A specimen in Fassls collection, from Co- 

 cilrhm. roico in Bolivia, has a lemon-coloured ground-colour, without any white at all; I call it ab. citrina ab. nov. 



— Not rare. 

 ncmea. B. nesaea G. and S. (134 f) looks like the ab. citrina of the preceding species, but it is somewhat 



smaller and has a twice as broad black margin traversed by a j'ellow thin stripe running between 2 metallic 

 hiicaeiiita. lines. Costa Rica, Chiriqui. — bacaenita Schs. (134 f) exhibits the yellow median area narrowed, particularly 

 in its costal part of the forewing, but otherwise it is allied to nesaea. Peru and Bolivia, taken yet at 

 cKiJicpen. an altitude of 300 m on the Juambari. — euprepes Bat. from the Rio Tapajoz is not before me; it has 

 likewise 3 yellow stripes through both wings, the foremost of which, however, is more remote from the base 

 of the wing. 

 haL-acnis. B. bacaenis Hew. (134 f). Smaller than the preceding, the j^ellow basal stripe and the submarginal 



elcganiuta. line as thin as a thread, the median area of both wings forms a white, conjoint oval. Ecuador. — elegantula 

 Hpffr. (134 f) scarcely differs, the .stripe at the base more ochreous-yellow as well as the line in the black 

 distal margin, this line being expandeel towards the costa of the forewing. Peru and Bolivia. — Common. 

 prima. B. prima Baf. This species, not lying before me, has likewise 3 yellow transver.se stripes; the fust 



runs along the inner margin of the hindwing, the middle stripe being obhque, the subapical one fine. On the 

 under surface one yellow stripe in addition and the outer one in the anal part of the hindwing forked. One 

 of the largest species. The forewings have a comi^lete me^tallic line before the border. From the Rio Ta- 

 ortlwiaciihi. pajoz. — This species is perhaps approximated by orthotaenia .s;jec. hov. (134 f) from Bolivia, in which, how- 

 ever, the median stripe in the forewing stanels straight, while the hindwings have a metallic line before the 

 drijades. border, the forewings, however, onlj- indications of such a line before the apex. ■ — dryades Dogn. is presu- 

 mablj^ also allied to this species, but it is smaller, the median stripe reaches neither the costa of the fore- 

 wing nor the inner margin of the hindwing. it is strangulated in the middle, while the distal stripe is intei- 

 secteel in such a way that it is broken up on each wing into 2 spots (near the costal margin and the inner 

 margin). 

 creunis. B. cfcusis Hew. (134 e). Very easily recognizable by the common median stripe being white, above 



creushm. and below tapering and slightly bent like an S. Bolivia. — In creusina Stick. (134 e) lying before me from 

 Cuzco (Peru) the submarginal .stripe is as fine as a hah and often even obsolete for some distance. - — Not 

 rare. 

 Iiishon. B. hisbon Cr. {= hisboena Hbn.) (134 g). Much smaller than creusis; the median stripe slightly curved 



like an S, as in creusis, but on all the wings the distal stripe is greatly shortened, above and below. South 

 :onala. Brazil, rather rare. -^ In zonata Fldr. (= simbla Bsd., libna Bflr.) (134 g) all the yellow stripes are con- 

 siderably widened, particularly in the $, and behinel the (shortened) outermost stripe of the forewing, which 

 is mostly fusiform, we notice another small yellow spot in the anal angle of the forewmg. Mexico to Co- 

 c.rplcki. lombia. Common. — expleta Stich., on the contrary, denotes specimens in which the yellow spots in the distal 

 part of the wings have disappeared altogether or to some traces of them. Described from Honduras. 

 caprcuhis. B. capreolus Stick. (134 g) approximates the preceding species, but the fusiform distal spots are co- 



herent with the j-ellow median band by means of a broad pedicle. Colombia.
