and in the course of the lines, to judge by Hampson's figure and de- 

 scription. His male specimen from San Salvador is probably the 

 present species, 



ISCADIA LEENA Druce. 



Gadirtha (?) leena Druce, Biol. Cent.-Amer., Lep. Het., vol. 2, 1898, p. 508. 



4. Porto Bello, March, 1912 (Busck); Cabima, May, 1911 (Busck). 



The present species does not agree well with the characterization 

 of the subfamily "retiaculum of male bar-shaped," the structure 

 being a fold, twice as wide as long. But as Casandria stroca Schaus 

 has an enthely smiilar structure and Iscadia aperta Walker has no 

 retmaculum at all, the species may be included here among the other 

 exceptions. 



MEDAVA DIMINUTA, new species. 



Fore wing whitish gray, shaded with purple at base and narrowly 

 along costa; inner Ime slender, denticulate, broken into three black 

 points m the cell; outer Une denticulate, followed by whitish, starting 

 from costa above the large annular reniform, maldng a broad half 

 circle to below reniform, then to inner margm; subtermmal line 

 blackish, denticulate; terminal dots small, in a purplish shade. Hind 

 wing black on the margin, pale over the disk; fringe whitish. Ex- 

 panse, 18 mm. 



Type. — Male, No. 15919, U.S.N.M.; Corozal, Canal Zone, Juno, 

 1912 (Busck). 



Hampson's diagnosis of the genus Medava in his key ^ is in error in 

 placing it in the section "Palpi with the third joint long and dilated 

 at extremity." This joint is really short, as described on page 450. 



EGCHIRETES, new genus. 



Fore wing with veins 7-8 from end of accessory cell, 9 absent, 10 

 from top of accessory cell, 11 free. Hmd wing with 4 absent, 3 and 5 

 from cell. Palpi with the second joint fringed above with hair toward 

 extremity, thhd jomt moderate, tapered. Fore whig convex at base 

 as in Sarrothripa. 



Type of the genus. — Egchiretes nomimus, new species. 



EGCmRETES NOMIMUS, new species. 



Dark gray; fore wmg with a white patch on inner margin at basal 

 third; subbasal line double, slender, blackish, from costa to sub- 

 median; black dashes on subcostal and a spot on submedian; mner 

 line blackish, waved, filled by whitish; two black discal points in a 

 white spot, followed by a white streak toward apex; outer line black, 

 fine, single, denticulate, gently curved, with an mward dentation at 

 vein 2, followed by white; subtermmal line whitish, preceded by 

 fuscous, broken by a white spot below costa; minute terminal black
