630 EUSELASIA. By Dr. A. Seitz. 



a .smaller spot in the middle of the hindwing, and a third one before the anal angle of the hindwing. Central 

 America and Colombia. 

 Judnuli. E. hahneli Stgr. (= hahneli Mengel) (122f) from the Upper Amazon, to the south as far as Bolivia 



(Coll. Fassl) and South Brazil, has beneath almost exactly the same markings as argentea, but bone-yellow 

 instead of silvery; above the liase of the forewing and the -whole hindwing of a bright red, excejst the costal 

 margin and the upper distal margin. The 5 is above more yellowish-red and at the hindwing only the costal 

 margin is blackish-liroA\ii. Near Rio de Janeiro rare; maybe more common in the north. 

 corduenna. E. corduenna Hew. (122f, g). Above black, the basal part of the forewings and the anal part of the 



hindwings of a magnificent blue reflection. Beneath silvery yellowish-giey with a dark border and 3 transverse 

 stripes the proximal one of which runs differently, according to the finding-places, sometimes in a straight 

 line, sometimes curved, forming a pointed or an obtuse hook on the hindwing. From Central America through 

 Colombia, Ecuador and Peru as far as Bolivia and Central Brazil. Not rare. 



(ilfineiia. E. alcmena Drc. Forewing dark brown, the palest at the apex of the forewings. Under surface light 



tan-coloured, both wings in the middle traversed by a narrow orange band; between the latter and the border 

 a faint, brown undulate line; hindwing with a submarginal row of small black spots the fifth of which is the 

 largest. Smaller than the following species. Ecuador. Unknown to me in nature. 



'"■'''''•■• E. urites Hew. (122 a). Above blackish-brown with a very faint blue gloss, beneath yellowish silvery- 



grey with only one transverse line being slightly curved. There is quite a number of equally coloured Euselasia 

 being distinguished only by the course of this transverse line. The course of this line of the under siu-face has, 

 already since Hewitson, been considered a characteristic mark of the species, but in corduenna, eugeon, thucy- 

 dides etc. being quite distinct species we may notice that this line itself does not even characterize the sub- 

 species. The forms being above brown, beneath silvery may, therefore, belong to few species distinguished 

 by the shape of the wings, the shading of the silvery area etc. 



euscpus. E. eusepus Hew. (122 a) is like iirites. but above without a blue gloss; the line of the under surface 



is on the hindwing farther away from the border, and before the anal angle, one part of this line (unfortunately 

 missed in the figure) is pushed forward towards the border. I have sjjecimens before me from Pozuzo (Peru), 

 in which this projecting part of the line is yet connected with the other links of the line, thus forming an inden- 

 tation being convex towards the border. This may be of a very different extent, the most in South Brazil and 

 Bolivia, the least in Peru where we already notice transitions to writes from the Amazon, sometimes ^^itli cj^uite 

 a faint blue reflection; there the line of the under surface mostly runs continuous, e^/se/ws always has a silvery- 



cumcnes. white forehead. — eumenes Hew. Here the under surface-line is not pushed forward before the anal-fold, but 

 in typical specimens still somewhat interrupted before the anal fold. On the whole, eumenes has somewhat 

 more pointed wings; from the Amazon. — Our figure shows a very similar form, somewhat larger, the under 

 surface-line uninterrupted, the under surface itself of a purer silvery colour, without a yellowish tinge; nume- 

 rous equal specimens from Monte Tolima, captured by Fa.ssl, and in the Paris Museum. The $ is beneath 

 exactly like the ^, whereas the $ of eusepus is beneath lustreless greyish-brown; I call the form which may 



eupafnt. be a distinct species, eupatra subs'p. nov. (122 a as eumenes). — In cataleuca Fldr. from Mexico the jjostmedian 

 line is absent altogether and the under surface exhibits a very light silvery area without any markings. 



niatutii. E. matuta Sclis. (142 c) described from Costa Rica, frcun where it is before me from Orosi, 1200 ni. 



Above the black forewings have a yellowish-red, small discal spot, the hindwings a brownish-red lustre. Under 

 surface silvery white with a straight dark postmedian line and some small black dots before the border of the 

 hindwing. 



bettina. E. bettina Heu\ (122 a). Above dark brown with a scarcely noticeable light-bluish lustre; beneath 



yellowish grey, of a bronze gloss, before the middle of the border of the hindwing a small dark dot. From Cen- 

 tral America to Ecuador. Locally common. 



caiularia. E. candaria Drc. (142 c). Like the preceding species, but beneath golden yellow, lustreless. The 



small dot before the middle of the border of the hindwing is larger and some more finer ones are before the 

 border of the anal part. Colombia, not rare; often in the ,,Bogota"-consignments. 



pheJlmi. E. phelina Drc. Larger than eumenes. Upper surface one-coloured light brown, undey' surface of 



a pure white. The forewing is, from the costal margin to the inner margin, traversed by 5 narrow, pale brown 

 bands; the distal margin is brown. Hindwing traversed l)y 3 brown bands not reaching as far as below the 

 cell; close at the distal margin, in the centre, there stands a large black spot and a small one nearer to 

 the anal angle; the space between the two spots is yellow. A submarginal. undulate brown band traverses the 

 wing from the apex to the anal angle. From Maracaibo (Venezuela). 



f'umedi((. E. eutnedia Heir. (= ophias H.-Schaff.) (122d). Above quite blackish-brown, without any gloss 



and reflection. Beneath the transverse line is red, as well as the border of the hindwing, in which we notice 

 black, white-edged dots. From Colombia to Peru, not common. Typical specimens from Colombia have a 

 very dentate border of the hindwing; in the much smaller Peru-specimens the latter is rounded, the costa
