1048 Additions: HESPERIDAE. By Dr. M. Draudt. 



Genus ]SIiab<loi«les. 



Rh. cellus Bsd. d: Lee. (p. 871). According to the more modern conception psetidocellus Cool, is a di- 

 stinct species. 



Rh. casica H.-Schaff. (p. 871, t. 169 b). Add as synonym: (orestes Lintn.) 



Genus I^ascus. 



Insert after N. pJiocus dianina (p. 873): 

 phinfias. N. phiiltias Schs. Hereto belongs as the $ the insect figured as a variety of phocus in the supple- 



ment of the ,,Biologia Centrali-Americana". Above dark brown, basal area and proximal margin dusted 

 with orange-brown. Spots as in phocus, though with another small one between the radial veins. Hindwing 

 quite orange-brown, but at the costal margin and narrowly at the distal margin blackish-brown. Otherwise, 

 also beneath, like phocus. Expanse of wings: 55mm. Costa Rica (Guapiles). 



N. euribates Cr. (p. 873, t. 170 a) has recently also been reported from North America, the correct 

 name of the species being hesus Wiv. d; Hew. (nee. Dbl.); euribates Cr. is very doubtful. As another questio- 

 nable synonym add : etias Heiv. 



Genus Murgaria. 



Insert after M. albociliata Mob. (p. 875, t. 170 c): 

 coyote. M. coyote Skiym. In the exterior hardly discernible from the preceding species; fringes of hindwings 



more or less intensely striped brown, in albolineata only at the apex and anal angle, in the centre they 

 are always purely white. The genital organ, however, is quite different in both. Texas and Arizona. 



Genus Cogia. 



Insert between C. hippahis Ediv. and C. calchaS H.-Schaff. (p. 877, t. 170e): 

 oniis. C. cutis Skinn. Ground-colour dull brownish-black like in hippalus, the forewing usually with 2 



postdiscal hyaline spots between and above the median veins and distinct subapical spots whereby the species 

 differs from the otherwise very similar calchas. Texas in August. 



Genus Tliorybes. 



nevada. Th. nevada Scddr. being on p. 880 placed as a synonym to Th. mexicana H.-Schaff. has of late been 



regarded as a distinct species with aemilea Skinn. as synonym. In the exterior both are quite the same, but 

 the genital organ is said to be constantly different. The valve of mexicana has a convex end and is only very 

 feebly serrate, that of nevada has a concave end and is strongly dentate. Furthermore add after mexicana: 

 confusis. Th. confusis Bell, resembles pylades Scddr. so much that it is hardly discernible, and mixed up with 



it in most of the European collections; the cJ is easily distinguished by the absent costal fold. The genital 

 organ is very different by confusis having the bipartite uncus of the pylades-growp and the penis of Cogia 

 calchus, thus connecting the two genera to a certain extent. 



Th. mysie Dyar (p. 880, t. 171 b, c) is also known from Arizona and is placed to the genus Phaedinus 



by LiNDSEY. 



Th. pylades Scddr. (171b) being on p. 880 placed to the genus Cocceius belongs to Thorybes. Add 

 iimacuhiict. heveto yet: ab. immaculata Skinn. in which the hyaline spots are almost extinct. Also the .species following 

 pylades (p. 880): drusitis Edw. has of late been placed to the genus Thorybes. 



Genus Hydraeuoinia. 



nebulosa. H. nebulosa sp. n. (178 b) is to be inserted after H. orcinus, p. 881. Larger and with broader 



wings than orcinus, but in the anatomical marks ^^-ell fitting to it. Light greyish-brown, covered with long 

 olive hair-scales, rather thinly scaled, disc of the hindwing partly sem-transparent. Forewing almost with 

 the same hyaline spots as orcinus, but the cellular spot is divided into 2 long parallel ones, the one behind 

 it is d-shaped with very long, narrow sides. Beneath the same, but without the long hairing. The hind- 

 wing in the disc shows a large white, semi-transparent spot extending from the costal margin to the inner- 

 marginal fold. 1 (J from the Songo (Coll. Fassl).
