646 MESOSEmA. By Dr. A. Seitz. 



patruelis. the whole hindwing has been denominated patruelis Stick. The $ exactly resembles above that of metope, it 

 has only in the middle of the border of the hindwing a little white, but the hindwings beneath are white almost 

 to their whole extent (not only in the distal part). 5$ with a stripe-shaped white brightening across the whole 



bettina. width of the -wings are bettina Stick. I do not know them and doubt whether they belong to this species. 



jeziela. M. jeziela Btlr. {= egabella [(J] Stfjr.) (126 b, misprinted in jeziella). Similar to egabella, but the 



blue and white area of the fore^^ing runs to the inner margin as a broad transverse band; the transverse stripes 



Sylvia, of the hindwing above incomplete. Colombia to Ecuador. — In sylvia Drc. (= thyene Stick.) (142 b) from the 



Rio Songo in Bolivia the light patches of the upper surface are blue, only in the middle striated white. • — ■ In 



limbata. Hmbata Stick, the black border of the hindwing being other-\^'ise broad only at the apex, is broad round the 



ihyestes. whole wing, and the 3 anterior transverse lines of the hind\^ing traverse the whole wing. ■ — thyestes Drc. (126 b) 

 from the Chanchamayo is the same, only the inner half of the band of the forewdng is blue, the outer half white. 



elegant. From Peru. — elegans Latky (126 c) is above quite similar, but larger, the lines of the under surface finer, 

 duller, the fore^^'ing has no distinct second eye-spot below the central eye-spot, and the centre of the hind- 

 wing beneath is less sharply marked; from La Merced in Peru. Single and rare. 

 coea. M. coea Hhn. (= philocles $ Cr., nyctea Hffgg.) (126 a, as coeca). According to Stichel (Riley i. 1.), 



this species being scarcely comprehensible from Cramer's coarse figure seems to be identical with ti-aga Hew. 

 It resembles in both sexes pretty exactly the ?? of the preceding species, but the margin of the hindwings 

 is broader white. Moreover, on Hewitson's figure the left wings of the $ are differently marked from the 

 right ones, and the figiu'e depicted as the ,^ of it does at least not everywhere belong to the form represented 

 by the $-figure. The lines traversing the white distal part of the hindwing are incomplete. Amazon. — 

 lafo. lato Stick, with more white in the hind-ndng is said to originate from the Rio Tonantins. — scotina Stick, and 

 lacernata '^ccrnata Stick., unknown to me, come from Guiana ; they are said to be very similar to coea except little differen- 

 ces in the marking. 

 minos. M. tTiinos Heu\ (136 a) the hindwings of which, in typical specimens, do not exhibit such a pure, 



but a more dirty white ground-colour than in our figure; but they vary at every habitat and show sometimes 

 stouter, sometimes thinner transverse lines of the hindwing, occurring on the Lower Amazon and in Central 

 Brazil. Here the subniarginal nebulous lines exhibit in the ^ beneath, in the $ also above knotty swellings 

 before the middle of the border of all the wings, which are absent in the following species being otherwise 

 lelrophfhal- similar. In order to use the names stated, we may denominate as fa. tetrophthalma Stick, specimens with 

 '.""■ especially much, modica Stick, specimens with very little white on the upper surface of the wings; these forms, 

 however, are not bound to certain countries, but only to flying-places. 



melaene. M. melaene Hew. (126 a). According to the author, this species differs from the allied traga (= coea) 



chiefly by the course of the (10) stripes of the hindwings. A more distinct mark is a shining, leaden-grey lustre 

 of the darker parts of the forewings, being very ^^ell reproduced by oiu- figure. As in minos, the gi-ound-colour 

 may be in the marginal part of the hindwings of a pui-e or dirty white, even almost brown, which is especially 

 prominent between the second and third most exterior stripe of the hindmngs running in contrary curves. 

 pinguilenta. Sometimes also the forewings exhibit a white transverse band before the marginal third (pinguilenta Stick.). 



lupcrca. Guiana, Amazon. — luperca Stick, described according to a single $ from Pachitea in Peru, is a species unkno'w'li 

 to me; it is said to have a light band running thi'ough both wings and a median eye-spot also on the hindwing. 



mosera. M. THOsera Hew. looks almost exactly like a melaene, especially the gi'eyish-green, slightly metallic 



lustre of the forewing which is lackmg in the other Mesosemia except melaene, occurs here also in the ^, but 

 the distal marginal part of the hindwing is not ^^•hite, but as dark as the gTound-colour, and the exterior stripes 

 of the hindwing are curved parallel to each other, not contrarily. By this the marking gets very much like 

 that of minos ^^•hich, however, has distally lighter hindwings. 

 melese. M. melese Heiv. (126 b) resembles the preceding, though it is somewhat smaller and the 5 has a 



distinct central eye-spot on the hindwings, whereas the $ of mosera exhibits only a dot. Unfortunately the 

 figure (according to a badly set specimen) shows the characteristic eye-spot of the hindwing partly covered 

 by the forewing. Para. 



myonia. M. myonia Hew., being likewise near to mosera and minos, is marked like the former, but beside 



the ground-colour in the distal half of the hindwings, also the ground of the ellipse enclosing the eye-spot of 

 the forewing is brightened bj' yello-w. Hewitsois himself believes that the species may be a $-forni of philocles; 

 it is certainly nearly allied to it. From the Amazon. 



vieihion. M. methion Hew. likewise approximates the minos-melaene-groujp, but it has a very different appearance 



owing to a rather broad white transverse band beginning broad at the costa and running almost straight towards 

 the anal angle of the forewings. The submargmal line of the hindwings exhibits the knots before the middle 

 of the border of all the wings very thick and distinct, above and beneath. In typical specimens, however, 

 the second and third exterior stripes of the hindwing are combined to a broad dark band by the space between 

 being filled up by dark browir. Such specimens occur from the northern coast of South America in the east 

 as far as to the south of the Amazon; in Peru the space between the second and third last stripes of the 

 hindwing is filled up broad in white whereby the white band of the fore-ning seems to run also through the 

 hindwing. The bands, however, vary in width alreadj^ in quite closely situated habitats.
