THEMESION; TITKESIS; MEGALEAS. By Dr. M. Draudt 



186. Genus: Tlieniesioii G. & S. 



Tlie long antennal club exhibits a very long, reverted apex; last palpal joint short. Cell of forewing 

 shorter than two thuds of the costal margin; the abdomen projects beyond the hindwing. Body very robust; 

 middle tibiae without spines; posterior tibiae with 2 pair of spurs, the upper being very short. 

 crrirma. Th. certima Hew. (= lebbaeus Hew., lota Hew.) (190 e) is above rather similar to T. tnyna {IQO e). 



Blackish-brown with 4 large, hyaline white discal spots and 2 small subapical spots. Hindwing with 1 or 2 

 small postdiscal dots. The under surface is lighter, in the middle of the forewing darker. The hindwing exhibits 

 a dark dot at the cell-end, and 4 behind it, 2 of which are pupilled white. Panama to Venezuela. 



noseda. Th. noseda Hew. (= brinoides Mschlr.) (190 e). Above dark brown, towards the base with a slight 



violettish-brown tint, a white cellular spot and 3 postdiscal ones, the submedian one of which is the smallest. 

 Hindwing with a white spot behind the cell. Fringes ochreous-brownish. Beneath the costal margin and apex 

 of the forewing as well as the whole hindwing are violettish-grey, the disc and inner-marginal part of the forewing 

 black, marked as above. Described from Surinam. 

 alda. Th. alda Ploiz (190 d) is above blackish-brown, at the base of the costal margin of the forewing 



somewhat more reddish with 2 large discal spots, and 1 smaller one each behind and above them. On the hind- 

 wing there are towards the apex 1 to 3 small white spots which may also be entkely absent. Beneath the costal 

 margin and apex of the forewing and the whole hindwing are greyish-brown, tinted violet, on the hindwing 

 there are some small black punctiform spots. Brazil. 

 maroma. Th. maroma Mschlr. (190 d, e) is very similar, but the cellular spot is very much strangulated and 



farther remote from the spot below it, the submedian spot is yellowish, and there are besides 1 to 3 small 

 siibapical spots. Beneath darker brown than in alda, and mostly yet with a small white cellular spot 

 on the hindwing. Surinam. 



moeros. Th. nioeros Mschlr. (190 f). Here the cellular spot is above divided into 2, and below the subapical 



spots there are yet 2 small punctiform spots farther towards the margin. Body, base of wings, and hindwings 

 are haired olive-brown. Beneath the costal margin and apex of the forewing as well as the whole hindwing 

 are deep dark green with fine black veins, the hindwing with a black cellular dot and 2 or 3 behind it. Proximal 

 margin of hindwing blackish -gi-ey. Described from Surinam. 



orhius. Th. orbius G. <£• (S". is smaller than certima (190 e), the discal spots ochreous-yellow, with one more 



submedian sjjot; the hindwing exhibits 3 postdiscal dots in one row. Beneath lighter, dusted with lilac. The 

 species very much resembles Carystoides sicania which, however, is withoxit the yellow submedian streak, the 

 discal spots being also differently placed and only one subapical spot being present. It also greatly resembles 

 Turesis lucasi and fheste (190f), but the short upper spurs of the posterior tibiae preclude theu- relationship 

 to the genus Turesis. From Nicaragua. 



187. Genus: Turesis G. dh S. 



Antennae ^/g of the length of the costal margin. Veins as in Carystus (p. 979). Body strong, middle 

 tibiae bare, posterior tibiae with double, long spirrs. 

 lucasi. T. lucasi F. (= complanula H.-Schaff., yema Plotz, hebon Mob., silacea Mschlr.) (190f). Above 



like Th. orhius, the spots larger, more whitish; hindwing with only one yellowish dot. Beneath lighter, more 

 reddish, the submedian spot of the forewing larger, more yellow. It somewhat resembles Thr. salius (191 e, f). 

 Panama to Venezuela, Amazon, Brazil, Antilles. 

 theaie. T. theste G. <& S. (190 f) is similar, smaller; the 3 discal spots are combined forming an angular 



spot parted by the veins; a small subapical spot, the submedian spot absent; hindwing without any spots. 

 Beneath lighter, more reddish, on the hindA\ing with a yellow cellular dot. Costa Rica. 

 broohsii. T. brooksii Weeks may belong hereto. Above dark brown with 3 white subapical dots, a white 



cellular spot and 2 postdiscal ones. Beneath black, spotted as above, at the costal margin and apex reddish- 

 brown. Hindwing reddish-brown, in the basal and inarginal areas darker with 2 white postcellular dots. Expanse 

 of wings: 5 cm. Venezuela (Suapure), taken at the end of luly. 



188. 



Genus: Ifegaleas G. & S. 



Different from Turesis only by the ^ scent-scale spot: it extends from the rise of the upper median 

 vein obliquely and interrupted somewhat before the middle of the submedian. Antennal club thick and long. 

 ':ynia. M, syrna G. <fe S. (190 e) is a very large species: above blackish-brown with a large, oblong, yellow 



cellular spot filling up the distal ^/^ of the cell; behind it and below it a very large tripartite spot, and 3 snmll 

 subapical spots. Hindwing with a cellular dot and 3 larger dots in the costal-marghial half behind it. Beneath 

 lighter, more reddish. Costa Rica.
