Zool., iv, 494, from the Bermudas; but it is different in 
shape (hindwing not toothed at R^, etc.), and is hardly a 
typical Thamnonoma —fovea undeveloped, face without 
hair-tuft. The antenna shows the Thamnonoma structure ; 
the hindtibia is rather short and thick, with hair-pencil; 
in the forewing SC^ is absent, SC^ connected by short 
bars successively with C and h 
171. Cyclomia ocellata (Warren), 
Gyclomia costipancta, ab, ocellata, Warren, Nov. Zool., vii, 
213 (1900). 
Santa Fe, Ocampo, August 1902, and Gran Chaco, near 
Florenzia, October 1902 (S. K. Wagner), in coll. Br. Mus. 
Described from Venezuela. Warren also mentions 
similar forms from Bolivia. 
172. Cyclomia vinos a (Dognin). 
Fidonia vinosa, Dognin, Le Nat., xii, 19 (1890); Lep. 
Loja, 62, tab. vi, 17 (1891). 
Metan, Salta, in coll. Dognin. 
Dognin’s type was from Ecuador. The species also 
occurs in Colombia, Bolivia, and I think Peru. The head¬ 
quarters of the genus Cyclomia, would seem to be about 
the equator, and northward to the West Indies. The 
present species and the preceding are the only stragglers 
yet detected in Argentina, and even they have not been 
found very far south. 
173. Dyscia SERENA (Dognin). 
Dyscia serena, Dognin, Ann. Soc. Ent. Belg., 1, 118 (1906). 
Buenos Aires, type in coll. Dognin. 
174. Thysanopyga strigata (Warren). 
Thysanopyga drigata, Warren, Nov. Zool., xiv, 293 (1907). 
Ciudad de Tucuman, April 1903, type (^) in coll. 
Rothschild; La Rioja, one ^ (Dr. E. Giacomelli), in coll. 
L. B. Prout. 
I know of no specimens but these two. My ^ is less 
strongly dusted with rust-colour than Warren s type, but 
of course it is impossible to say from a couple of specimens 
whether the variation is sexual or local or individual.
