,584 CHIMASTRUM; BAEOTIS. By Dr. A. Seitz. 



C. sponsa Stgr. (135 g). .Similar tu the preceding, but aliso the distal area is golden green, except 

 a narrow border, a dark siibmarginal hne and a dark large spot before the apex of the forewing. On 

 the Jurimaguas. 



57. Genus: C'liiiua!i4triiin 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 silken 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. 



Ch. argenteum 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. 



Ch. carnutes Hew. (128 /a as carnutus). Silky 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 

 conunon. 



58. Genus: ISaeotin Hbn. 



Tiny, black and yellow, sometimes also white and black butterflies flying about in the snnshine during 

 day-time, with a delicate body, a somewhat projecting apex of the forewing 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. 

 /(•/(.,•. B. felix Hew. (134.f). White 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 

 jcVu-i.'^.iinui. the middle of the inner margin on the hindwing. Bolivia and Peru). — In felicissima Thru. (134 f) from Ecua- 

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

 cilriiia. roico in Bolivia, has a lemon-coloured ground-colour, without any white at all; I call it ab. citrina ah. nor. 



— Not rare. 

 nesaea. B. nesaca G. and S. (134f) 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 yellow thin .stripe running between 2 metallic 

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

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

 cinnepcs. 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. 

 ha<:acii\s. B. bacaenis Hew. (134 f). Smaller than the preceding, the yellow basal stripe and the submarginal 



etcyaniula. 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 expanded towards the co.sta of the forewing. Peru and Bolivia. — Common. 

 pr'una. B. prima Bat. This species, not lying before me, has likewise 3 yellow transverse stripes; the first 



runs along the inner margin of the hindwing, the middle stripe being oblique, 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 complete metallic line before the border. From the Rio Ta- 

 ortliiilacniii. pajoz. — This species is perhaps approximated by orthotaenia A;>ec. wov. (134 f) from Bolivia, in which, how- 

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

 drijadcs. border, the forewings, however, only indications of such a line before the apex. ■ — dryades Do(jn. is pitsu- 

 mably 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 intci- 

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

 margin). 

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



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

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

 rare. 

 ItUbiin. B. hisbon Cr. (= hisboena Hbn.) (134 g). Much smaller than cre.usis -..ihe median stripe slightly cuived 



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

 ::(„iiit(i. Brazil rather rare. — In zonata Fldr. {= simbla Bsd., libna Btlr.) (134 g) all the yellow stripes are con- 

 siderably widened, particularly in the ?, and behind the (shortened) outermost stripe of the forewing, which 

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

 cviileta. lombia. Common. — ^ expleta *S'<ic/i., 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. 

 rapmiliis. B. capreolus Stich. (I34g) approximates the preceding species, but the fusiform distal spots are co- 



herent with the yellow median banel by means of a broad peelicle. Colombia.
