blue marginal band, sometimes there is a large red spot which mostly grows very extensive in the ?. Very 

 common and widely distributed from Central America to Colombia, Guiana and the Amazon. 



6. Venulius- Group (Paiivarria Kaye). 



venulms. Th. venuHus Cr. (153 a). Above lustreless greyish-blue, beneath likewise light-blue with 3 submarginal 



blackish bands, the proximal one mostly red-brown; between the median veins of the hindwings there is in 

 the middle band a black spot being above bordered by orange. Widely distributed, but apparently very rare 

 from Guiana to Bolivia (Eio Songo). 



7. Satyroides- Group {Macusia Kaye). 



satyroides. Th. satyroides Hew. (147 c). In the species of this group the broad costal space of the forewings 



is covered with long hairy scales directed downward. ^J above dull violettish-blue, $ brown, hindwing with 



an orange-brown anal eye spot, beneath very similar to venulius, cj more greyish-blue, $ brown. Amazon, 



Rio, Sta. Catharina. 



temathea. Th. temathea Hew. (147 c) is above the same, beneath, however, the hindwing exhibits another 



transverse band nearer to the base. Amazon. 

 latreillei. Th. latreillei Hew. (147 c) we include here, because the costal margin of the forewings exhibits 



the same hairy covering and also beneath the scheme of markings is similar The shape of the wings is very 

 characteristic by the stunted apex of the forewing and the deep indenture at the proximal margin of the hind- 

 wing above the anal lobe. The tails are much broader than in the preceding Above metallic dark blue, beneath 

 brown with more intensely red-brown transverse bands and rows of lunular spots. Brazil (Sao Paulo, Sta. 

 Catharina, Pt. Alegre) to Paraguay. 



8. Assula- Group. 



assula. Th. assula spec. nov. (153 a) is a very peculiar animal without any closer relations to other groups. 



By the deep indenture above the very well developed anal lobe and the slightly stunted apex of the forewing 

 its shape resembles latreillei, but the hindwings exhibit only a broad, almost spoon-shaped tail. Above unicolor- 

 ously deep purple-brown, the anal lobe and an indistinct marginal line on the. forewings towards the hinder- 

 angle deep chestnut-red; the base of the fringes particularly at the anal lobe and some scales in the centre of 

 the apex of the tail bluish-white. Beneath the forewings are brown, towards the apex dusted in white with 

 a lighter line beyond the centre as far as the lower median vein. Hindwing of a deeper blackish-brown; from 

 the centre of the costal margin proceeds a lighter stripe ending directly in the tail with a distally concave bend 

 and being distally strewn with single white scales and being united in front of the border with one row each 

 of lighter lunular spots coming from both sides; in the anal lobe and in the cell-spaces between the median 

 veins there are carmine spots standing behind; at the proximal margin some more, irregular, white-scaled 

 markings. The base of the fringes white, more distinct than above. Described according to 2 $9 from Colombia, 

 a fresh one from Bogota, a much-flown one without tails from the Monte Socorro, from the Coll. Fassl. 



9. Marsyas- Group. 



marsyas. Th. marsyas L. (147 d) is a well-known, large species with an almost falciform apex of the forewing 



which, however, varies in its development, above beautifully sky-blue with a broad, jet-black apex of the 



forewing. Beneath lilac-grey, on the hindwings towards the proximal angle white strewn with mildew-green 



cybele. scales, with black spots and linear markings which are well reproduced by our figure. ■ — cybele Godm. <fe Salv. 



is an insignificant side-form with distally deeper blue wings. From Panama to South Brazil. 

 damo. Th. damo Drc. (147 d) is a species hardly separable from the former. It is above lighter and more 



silvery-blue than marsyas and is without the broad black apex of the forewing. In its size and the development 

 dorcas. of the falciform apex of the forewing it is just as variable as the preceding. — dorcas Drc. is a Peruvian form 

 with distally deeper blue forewings, and in the $ the margins of the wings are narrower blackish-brown. The 

 species extends in the north as far as Mexico, to the south as far as Ecuador; it very often flies at the skirts 

 of the woods, but it is difficult to capture, as it flies very high. 



10. Theocritus- Group {Mithras Hbn.). 



iheocrifvs. Th. theocritus F. (= nepia Godm. d; Salv.) (147 e as nepia) is a very unique species, above almost 



silvery, the distal half of the forewing blackish-brown ; the 2 is somewhat bluer. Under surface blackish-brown 

 with rows of metallic-green spots. Distributed from Mexico to Colombia (Muzo).
