Th. braescia Hew. is also very much like molion, but the bases of the wings are quite brown, without hraescia.

Th. uridon Dyar is above black, on the body and bases of the wings bright metallic blue; forewing uridon.

 basally white, on the forewing an oblique white band, widened below, the ground-colour before and behind

Th. hyas Mdb. is above brown, at the thorax and bases of the wings metallic blue; the forewing hyas. 

 shows 4 white hyaline spots beside the long scent-stripe: 2 dots in the cell end at the opposite edge each, two 

 medium sized spots behind it, and a subapical dot. Fringes dirty yellow. Under surface red-brown, at the 

 apex and distal margin of the forewing lilac ; below the apex there is a brown band extending down to the lower 

 median vein. The hindwing is lilac with 2 red-brown bands, one at the costal margin, the second in the middle ;

Th. nanea Hew. (191 d as nannea) is above similar though much darker, the spots of the forewing mmca. 

 smaller, hindwing without any green. Beneath the inner-marginal part of the forewing and the whole hindwing

 with a dark transverse band. Costa Rica to the Amazon. 



Th. seron G. d; S. (= saron Mob.) (191 d) shows on the dark brown upper surface 2 oblique post- seron. 

 discal spots, the cellular spot is absent. Beneath besides with a sul)2nedian .spot. Hindwing monotonously 

 brown, at the base green. Fringes ochreous-yellow. Honduras. 



Th. aurifer G. & 8. (191 d). Above blackish-brown with a grey stigma. Forewing in the distal aurifer.

 larly to them 3 subapical ones. Under surface red-brown, forewing spotted as above; hindwing with 7 golden 

 .spots : one in the cell-end and 6 in a row behind it ; the proximal margin is ferruginous-brown, the eyes are bordered 

 with red-brown. Costa Rica. 



Th. theodora Ehrm. we only place here on account of a certain resemblance to aurifer; it is described iheodora.

Th. salius Cr. (= antoninus Latr.) (191 e, f) is distinguished by the light violet basal area of the salhis.
