640 MESOSEMIA. By Dr. A. Seitz. 



reddish yellow- and white-marked under surface and a band of the forewing being entirely dissolved into spots 



in an anal direction. Fassl discovered it in the valley of the Rio Aguaca (Western Cordilleras of Colombia. 



monochro- The hindwings are here without bands on both surfaces. — moiiochroma Stich. (125 a) from Peru has the ground- 



'""■ colour, size and shape of wings of bacche, but the white band of the forewing is absent altogether and beneath 



coronata. the white marking is reduced. — coronata Stich. has the macular band of the forewings more curved and also 



on the hindwing a macular band. Ecuador. — The large forms are rare. 



maraena. M. marsena Heiv. Size, shape and exterior like in semivitrea jorm. nov. (125 a), except that the hyaline 



brightening covers also the whole disc of the forewing and the hindwing as far as to the base. The typical m,ar- 

 poJt/phisia. sena comes from Ecuador, but it is not common; semivitrea originates from Huanaco in Peru. — polyplusia 

 Stich. is an intermediate form in which only a chain of obsolete hyaline spots passes behind the central eye- 

 spot; from South East Peru. 



phelitxi. M. phelina Fldr. (125 a) has entirely the marking and colouring of the preceding and varies also 



equally, but the forewings are more stretched, the border more uniformly round, the hindwings in the middle 

 of the border neither cornered nor protracted. In and behind the cell of the forewing, and between the veins 

 of the hindwing, there are bright white patches, so that the type of an Ithomiid from the same region {Leuco- 

 thyris tigilla) is produced. Except in the shape of the wings, there is a chief difference in the much smaller 

 eye-spot of the forewing, as well as in the band of the forewing being less hyaline than M'hite-scaled. Also of 

 this species there exists a form exhibiting the marking of polyplusia, but being immediately distinguishable 

 as a j)Jielina-iorm by the small eye-spot, the hindwings being not angular and the white-coloured spots of the 



analoga. forewing; Fassl took it on the Upper Rio Negro (Colombia) at an altitude of 800 m; I denominate it analoga 



minima, sitbs'p. nov. — minima subsp. hov. is an only half as large form from Villa vicencio, likewise dicovered by Fassl. 

 It is so small that it might be taken for a Compsoteria or Ithom.iola; above almost exactly coloured like analoga, 

 but beneath all the light places are more densely scaled in white. 



V. Group, ((jaaidioli- and telegoniformes Stich.).

kings or a metal- b lu e b a n d. 



rjaud'wlum. M. gaudiolum Bat. (125 b). ^ above black, forewing with a broad blue oblique band, hindwing with 



an equal distal band. 9? oi^ both sides similarly marked as the (J beneath; with a double transverse streak 

 in the middle of the wings, a distinct central eye-spot and a dull transverse shade; above the distal part of 

 the wings has a more or less bluish tinge. Mexico to Costa Rica, Rare. 



(jntiiiJi.". M. grandis Drc. (125 1)) is very similar, larger, beneath tiiere is another eye-spot below the middle; 



tiie (J has, besides, more sharply angled hindwings, and the blue band of the forewing is steeper. None of tlie 

 $9 examined exhibits a white band. The butterflies inhabit the southern part of Central America and are rare. 



sii))/]iiiiii. M. sibyllina Stg-r. (125 b) probably scarcely belongs here. It lies before me in but one $ from Cachabe. 



It somewhat differs from Staitdinger's figure, since the enclosures of the eye-spot in the cell and the eye-spot 

 below the cell, which are noticeable only beneath in StaudinC4Er's figure, are here distinctly seen also above. 

 Undoubtedly rare; maybe the 9 of a (J known long ago. The (^ is said to be blue above, according to Stichel. 



ielcgoiir. " M. telegOHC Bsd. (= lamachus Hew.) (125 f). Shape like gaiidiolus, but the forewing with a central 



eye-spot and light bands. Hindwings violettish-blue. Honduras to Costa Rica; it occurs also yet beyond the 



Mexican frontier, where it is, however, soon i-eplaced by a form with indigo-(not violettish-)blue hindwings; 



tctricn. this is tetrica Stich. {— methion G. and S.), which lies before me in numerous specimens from Misantla, where 



it seems to be very common. Fassl sent from the Cauca Valley specimens the hindwings of which are more 



iDiiiaiia. uniformly covered with lilac, without the indigo-blue costal part; this is amiana Fldr. (125f) occurring from 



iiiirniitim. Venezuela to Panama, where it is replaced by the typical telegone. — paramba Drc. (125 f) from Peru has very 

 dark forewings without bands above. In the hindwing the bands are incomplete, too. In the ^ the blue of 



iiiiiinnla. the hindwings extends on the inner marginal part of the forewing. — By the i. l.-name of amanda (125 g) there 

 was in Felder's collection a large form the bright, more lilac-blue colour of which covers both wings completely 

 in the ^ leaving only C]^uite a fine costal stripe of the forewings brown. Still more deviating is the 9 which has 

 a very much more metallic, almost silvery-blue distal part of the hindwing. In Felder's specimens there was 

 no patria stated, but there lie before me numerous similar specimens from Muzo and Guadalite in Cundina- 

 marca (Colombia) so that I presume here an alpine form. Interspersed like an island, from Nicaragua to Panama, 

 seems the occurrence of carissima Bates (125 g). It shows rounded hindwings with a black margin, the disc 

 of which is of an extremely bright metallic cyanous-blue lustre and without any markings and black stripes 

 at all. telegone occurs very locally and always deviating according to the flying-places, in which, however, it 

 is rather common.
