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



186. Genus: Tlieinesioii G. & S. 



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

 shorter than two thirds of the costal margm; the abdomen projects beyond the hindwing. Body very robust; 

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



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



Blackish-brown with 4 large, hyaline ^^'hite 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 pupUled white. Panama to Venezuela. 



noseda. Th. noseda Hew. (= brinoides MscMr.) (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 Plotz (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- 

 wmg there are towards the apex 1 to 3 small white spots which may also be entu-ely absent. Beneath the costal 

 margin and apex of the forewing and the whole llind^^ing are greyish -brown, tiiited violet, on the hindwing 

 there are some small black punctiform spots. Bi-azil. 

 iimroma. Th. maroma Mschlr. (190 d, e) is very similar, but the celliilar 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 

 subapical spots. Beneath darker bro'W'n than in alda, and mostly yet \\ith a small white cellular spot 

 on the hindwing. Sm'inam. 



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



spots there are j'et 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 gi'een with fine black vems, the hindwing with a black cellular dot and 2 or 3 behind it. Proximal 

 margin of hindwing blackish -grey. Described from Surinam. 



orhius. Th. orbius G. d; 8. is smaller than certima (190 e), the discal spots ochreous-yellow, with one more 



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

 species very much resembles Carystoides sicania which, however, is without the yellow submedian streak, the 

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

 Turesis lucasi and thesfe (190f), but the short upper spurs of the posterior tibiae preclude their relationship 

 to the genus Turesis. From Nicaragua. 



187. Genus: Turesis G. & 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 spms. 

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



like Th. orhius, the spots larger, more whitish; hind\^ing with onlj' one yellowish dot. Beneath lighter, more 

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

 Panama to Venezuela, Amazon, Brazil, Antilles. 

 theste. T. theste G. & 8. (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 hmdwing with a yeUow celliilar dot. Costa Rica. 

 brooksii. T. brooksii Weeks ma.j 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 margmal areas darker with 2 white postceUular dots. Expanse 

 of wings: 5 cm. Venezuela (Suapm-e), taken at the end of luly. 



syrna. 



188. Genus: Megaleas G. & 8. 



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. 



M. syrna G. & 8. (190 e) is a very large species: above blackish-brown with a large, oblong, j^eUow 

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

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

 lighter, more reddish. Costa Rica.
