ARGIDIA.—ORTHOGRAMMA. 399 
The Central-American specimens received show a considerable amount of variation 
in the colour of the upper, but not in that of the under, side. 
2. Argidia wedelina. 
Phalena Geometra wedelina, Cram. Pap. Exot. iv. p. 229, t. 397. f. M'. 
Argidia wedelina, Feld. Reise der Nov., Lep. t. 118. £. 29, Erkl. der Taf. 118. no. 29 (9) ?. 
Hab. Mexico, Jalapa (Schaus), Coatepec (Brooks); Panama, Chiriqui (ibde).— 
Cotomsia, Bogota?; Guiana, Surinam 1. | 
Cramer’s figure of this insect is a very poor one; but I have very little doubt that it 
is intended for this species. Walker has omitted it in his Catalogue. 
3. Argidia palmipes. 
Argidia palmipes, Guén. Sp. gén. des Lép. vii. p. 83471; Walk. Cat. xv. p. 1551’. 
Hab. Panama, Chiriqui (Ribbe, in mus. Staudinger).— VENEZUELA”; Guiana, Cayenne? ?. 
On the upperside this species very closely resembles some examples of A. calus, 
Guén. ; but on the underside it differs considerably. 
ORTHOGRAMMA. 
Orthogramma, Guénée, Sp. gén. des Lép. vii. p. 347 (1852); Walker, Cat. xv. p. 1552. 
Epitausa, Walker, Cat. x. p. 476, & xv. p. 1712. 
As yet, examples of only two species of this genus have been received from Central 
America. Walker in his Catalogue enumerated eight, seven being placed in Ortho- 
gramma and one in Lpitausa, all from South America or the Antilles; others have 
since been described by Butler, Felder and Rogenhofer, and Méschler. 
1. Orthogramma, coppryi. 
Orthogramma coppryi, Guén. Sp. gén. des Lép. vii. p. 348°; Walk. Cat. xv. p. 1553”. 
Epitausa letabilis, Walk. Cat. x. p. 477°. 
Hab. Guatema.a, San Gerénimo (Champion) ; Panama, Volcan de Chiriqui 2000 to 
3000 feet (Champion).—Gutana, Cayenne!2; Amazons, Paré?; AntiLtEs, San Domingo®. 
This appears to be a scarce insect in our region: we have only received three speci- 
mens, all captured by Mr. Champion. 
2. Orthogramma (?) lamida, sp.n. (Tab. XXXIII. fig. 10.) 
Primaries and secondaries uniform chrome-yellow, both wings crossed about the middle from the costal to the 
inner margin by a reddish-brown line edged on the outer side with pinkish-white, the costal margin edged 
with reddish-brown from the base about halfway to the apex, two zigzag indistinct lines crossing the 
primaries between the base and the central line, a faint zigzag submarginal line extending from near the 
apex of the primaries to the inner margin of the secondaries just above the anal angle; the underside 
pale brownish-yellow, the central brown line as above but very faint: head, antennw, palpi, thorax, 
abdomen, and legs pale chrome-yellow. Expanse 1? inch.
