"724 THEOPE. By Dr. A. Seitz. 



the hmdwing blue, in front of the border are fine blackish dots in a light halo. The under surface is unicolor- 

 ously whitish-grey with very fine dark dots on the hindmng and in the anal part of the forewing. Amazon. 

 phineus. Th. phineus Schs. Described from Limon in Costa Rica. Forewings dark browTi; cell posteriorly as 



well as the space below it as far as behind the middle of the wing bright blue, also the space between veins 

 3 and 5 up to close to the border. Hindwing likewise blue, only the costal margin and apex narrowly black. 

 Under surface light brownish-grey, hindwings with black marginal dots the largest of which at the anal angle 

 and below vein 3. 

 meihemona. Th. methemona Bat. is considerably larger than the preceding, the forewings form a more regular 



triangle; the disc and base of both wings are blue, sharply delimited against the broad black margin; under 

 surface light-brown. Forewing and hindwing with thick submarginal dots. Lower Amazon. 

 theritas. Th. theritas Hew. (143 g as thersitas) is larger and has a bright blue ground-colour with an intense 



lustre on the inner part of the forewing and on the whole hindwing. The under surface is light ochreous-brown 

 with 2 black submarginal dots in the anal part of the hindwing. Amazon. 

 diores. Th. diores G. & S. (143 h). Differing from the preceding species chiefly by the costa of the forewing 



being more stretched and the black in the forewing being more extensive. Under surface very much like that 

 of the preceding; in the anal part mostly only 1 dot. Mexico; mostly rare. 



virgilius. Th. virgiHus F. (143 h). One of the largest species varying exceedingly. Typical specimens come 



from Central America; the ^ has more than half of the forewing black, but no blue pupil in the black apical 



eupolis. part. The under surface is uniformly tinged in a pinkish brown. — eupolis Schs. (143 g) has the blue of the forewing 

 in the ^ confined to the basal part of the inner-marginal area; in the $ it is more violet, more extensive, and 

 in the black apical part is an indistinct blurred spot. The under surface is more flesh-coloured than brown 

 and has only 1 tiny eye-spot in the hindwing. Mexico; near Guerrero not very rare; before me also from Jalapa, 



polimela.&nd in a remarkably small, more lilac-blue Q from Honduras. — polimela G. & S. has the upper surface of 

 typical virgilius, but without distal-marginal dots of the hindwings; the black of the apical part in the 

 forewing somewhat reduced; the under surface of the hindwing without an eye-spot in the anal part. Colombia. 



caemlea. — caerulea Bat., finally, is the .South Brazilian form, is said to be more cyanic-blue than violettish-blue and 

 nobilis. the hindwing has darker veins and between them, small, dark submarginal streaks. ■ — nobilis Bat. is the Amazon- 

 form; it is particularly large and has a more yellow than brown or pinkish-grey under surface with several 

 archimedcs. small spots before the border. In some places common. — It may be that also archimedes F., unknown to me, 

 belongs into this group; it is said to be marked similarly above and to have a greyish-brown under surface. 

 The patria of this latter form not being knowTi, it is undoubtedly difficult to ascertain. 



speciosa- Th. speciosa G. cfc S. (— fasciata Lathy). Beneath just as monotonously coloured as the preceding, 



entirely earthy-grey with faint dark anal dots of the hindwing in a light halo. Above, however, also the ^ exhibits 

 in the black apical part a lustrous blue spot of a violet reflection, being by far larger than in the ?? of the 

 preceding species. Colombia. 



jmblius. Th. publius Fldr. (143 h). This butterfly, like the $$ of virgilius, has a bright blue spot in the black 



apical part of the forewing, but also in the q, where virgilius is without it. But besides the under surface is 

 entirely different, chestnut-brown with a more deeply browTi median shade of all the wings. Widely distributed 

 and not very rare. From Panama to the Amazon. 

 comosa. Th. coitiosa Stich. Also here the (J has in the apical black of the forewing a blue pupil, like in publius 



(143 h) to which the upper sm-face is said to be similar. (But according to the figure in the ,, Genera Tnsectorum", 

 this blue spot is at a different place, from that of publius, at the cell-end, whereas there it is nearer to the 

 apex.) The under surface, besides, is monotonously yellowish-grey, unmarked. Described according to a ^ 

 from. Pebas (Peru). 

 ialna. Th. talna G. cfc S. (143 h). From Honduras. Resembles virgilius (which, however, likewise flies in 



one form in Honduras) ; the blurred spot in the black apical part of the forewing is present, but otherwise the 

 blue of the upper surface almost entirely confined to the base of the wings ; the under surface exhibits a whole 

 chain of anal dots of the hindwing. 



cratylus. Th. cratylus G. <£• S. (143 e). This species, one of the largest of this genus, which we figure from the 



Chiriqui, neither in the q nor in the $ has the black apical part of the forewing blue-pupilled. It is imme- 

 diately recognizable by the somewhat irregular delimitation of the blue in the forewing, where it projects towards 

 the apex, and by the dark border of the hindwing. Panama. 

 ihooics. Th. thootes Hew. (143 i). Much smaller than the preceding, at once distinguishable by the blue of 



the forewing projecting behind the cell in a tip towards the margin and advancing a second time between the 

 lower median vem and the submedian, but here as far as to the distal margin. Undersurface unicolorously 

 greyish-brown, unmarked. Central America to the Amazon. 

 zosiera. Th. zostera Bat. Above similar to the preceding, but the blue more extensive, so that only a black 



marginal band remains being deeply indented in the middle. Under sm-face entirely different; the here brownish- 

 yellow wings are crossed by a brown belt. From the Upper Amazon.
