ORTHODES.—MESOGONA. 289 
de Chiriqui 2000 to 3000 feet (Champion, Arcé)—Coxromsia ; Ecuapor ; Sovru-rast 
BRAZIL. 
This species varies in colour from pale drab to dark reddish-brown: as a rule, 
specimens from North America are the palest, the most richly coloured being from the 
State of Panama. 
2. Orthodes lodebar, sp.n. (Tab. XXVII. figg. 17 ¢, 182.) 
Male. Primaries reddish-brown, darkest along the costal margin to the middle, and the dark colour beyond 
this extending half over the wing towards the outer margin, with three waved indistinct lines crossing 
from the costal to the inner margin, a yellowish-brown spot at the end of the cell, and a submarginal 
waved black line extending from the apex to the inner margin close to the anal angle; secondaries 
dark brown, with the fringe paler (especially so on the inner margin); the underside yellowish- — 
fawn-colour, the costal and the outer margins of the primaries broadly banded with reddish-brown, 
the apex of the secondaries slightly shaded with reddish-brown: head and thorax dark reddish-brown, 
the collar pale yellowish-brown, the abdomen dark brown with the sides and anus reddish-brown, the 
underside of the thorax, abdomen, and the legs yellowish-fawn-colour; antenne brown; palpi brown, 
paler in front. Female marked like the male, but with the spot at the end of the cell very much more 
distinct and of a pale fawzi-colour, and the underside more dusky. Expanse, ¢,2inches; 9, 12 inch. 
Hab. Mexico, Jalapa (Hége); Guatemata, Senahu (Champion); Costa Rica, Volcan 
de Irazu 6000 to 7000 feet (Rogers). 
This species is allied to O. cynica, but very differently marked. The Mexican and 
Guatemalan specimens are rather darker brown than the two from Costa Rica 
figured. 
3. Orthodes infirma. 
Orthodes infirma, Guén. Sp. gén. des Lép. v. p. 8757; Walk. Cat. x. p. 4467; Grote, List of North- 
American Moths, p. 31 (1882)%. 
? Orthodes curvirena, Guén. Sp. gén. des Lép. v. p. 374, t. 5. f. 12%. 
Hab. Norra America *.—MeExico, Coatepec (Brooks), Jalapa (Schaus, Hoge) ; 
GvaTEMALA, Volcan de Atitlan 2500 to 3500 feet, Senahu (Champion); Costa Rica, 
Volcan de Irazu 6000 to 7000 feet (ogers).—BraziL 124, Rio Janeiro (coll. D.). 
O. infirma and O. curvirena, Guén., are. probably one and the same species; the 
black bands on the body of O. curvirena shown in the figure are, I think, most likely 
caused by the abdomen being much pulled out. My specimens from Rio Janeiro are 
similar to those from Central America. 
MESOGONA. 
Mesogona, Boisduval, Gen. et Ind. Meth. Europ. Lep. p. 144 (1840) ; Guénée, Sp. gén. des Lép. 
v. p. 403; Walker, Cat. x. p. 472. 
Walker in his Catalogue includes four species in this genus, two from Europe, one 
from North America, and one from Mexico; the latter is unknown to me.
