RESTIDIA RUHA, new species. 



Male with the costal edge full and rounded at base over the tym- 

 panic vesicle, slightly emarginate beyond the middle; reddish brown, 

 the vesicle dark; Imes very faint, the outer most distinct, whitish, 

 double, finely crenulate, gently excurved above middle. Hind wing 

 gray-black. Beneath purplish, the hind whig with an outer pale line 

 defined by dark. Expanse, 10 mm. 



Female with the costa nearly straight; a very slight shallow emar- 

 gination near the middle. Purplish, the lines less distinct than in 

 the male, scarcely visible. Beneath more uniformly dark than in 

 the male, the outer pale line of hmd wing distmct. Expanse, 10 mm. 



Coty pes. —Male and female. No. 16275, U.S.N.M.; male, Porto 

 Bello, April, 1912 (Busck), female, Cabuna, May, 1911 (Busck). 

 Also 17 males and 40 females with additional localities Taboga 

 Island, February, 1912 (Busck); Corozal, Canal Zone, March, 1911 

 (Busck); November, 1912 (C. P. Crafts); Alhajuelo, April, 1911 

 (Busck); Paraiso, Canal Zone, January, 1911 (Busck); Trinidad 

 River, May, 1911, March and June, 1912 (Busck); La Chorrera, May, 

 1912 (Busck); Tabernilla, Canal Zone, May, 1907 (Busck). 



The males vary in color from light red to a dark purple like the 

 females. Range in size for males, 8-10 mm.; for females, 8-10 mm. 

 The females are constant in coloration, 



I possess specimens like these (except that veins 4-5 of fore wmg 

 are stalked) from Trinidad and French Guiana labeled " Lepidomys 

 fuscalis Hampson, cotype <? " [recta ? ], from Venezuela labeled 

 " Lepidomys cuprealis Hampson, cotype c? , type $ ," and one from 

 Mexico with the same label (fuscalis, cotype male). In this latter, 

 veins 4 and 5 of the fore whig are from the cell, as in the Panama 

 specimens. Lepidomys Guenee^ was described as a Noctuid and its 

 single species, L. irrenosa Guenee was credited to New York. The 

 name stood m our old lists, but I omitted it from Bulletin 52, United 

 States National Museum, as the late Prof. J. B. Smith stated that it 

 was not North American. Hampson did not include it m his papers 

 on the Pyralinse (1895-8), evidently havmg discovered that it was a 

 Pyralid only subsequently to that date.^ As the species L. irrenosa 

 is unknown to me, I use the new name Restidia, which can be made 

 a synonym if no differences appear. The nsunes fuscalis and cuprealis 

 of Hampson apply to the forms with veins 4-5 of fore wing stalked, 

 to light and dark males on one species, in my opmion. 



I have also specimens identified by Mr. Schaus as Lepidomys lineosa 

 Druce (Azamora lineosa Druce^), one from Mexico, one from Costa 

 Rica. They are not conspecific, and neither, perhaps, the true lineosa 

 from Ecuador, but they appear from Guenee 's description to be simi-
