BRACHYCORYIS^E; HESPERIA. By Dr. M. Deaudt. 



hrurmea. M. brunnea H.-ScMff. is extremely allied to the following, it is smaller with smaller hj^aline spots. 



jamaicoisis. Described from Cuba. — f. jamaicensis Jlschlr. (178 i) is probably only a local form from Jamaica. Large, 

 monotonously blackish-brown above and beneath ^^•ith 3 minute subapical dots and 2 more near the margin 

 below them. 



zephodes:. M. zephodes Hbn. (178 i) has nothing to do with E-phyriades otreus Cr. as was erroneously considered 



hitherto. Very similar to the preceding, somewhat smaller, and with narrower wings, blackish-brown with 

 5 minute, white subapical dots and 2 more proximally placed dots below them, and another one in the upper 

 cell-angle. Beneath somewhat lighter with traces of darker transverse bands across the hindwing. The $ has 

 much larger hyaline spots and 2 faded dark transverse bands before and in the middle, between which the 

 ground is partly dusted bluish-grey. Cuba, Bahamas. 



63. Genus: Bracliycorj^ue JIub. 



Antennal club with an obtviser end, shaft short, not curled. Costal fold very strongly fringed with long 

 hair-scales, inside bare. The middle and posterior tibiae exhibit long slender hair-pencils, the posterior tibiae 

 2 pair of short spurs, the anterior tibiae with end-spurs. Only one species: 



areas. B. arcas Dniry (= flyas Cr., velasquez Ltic.) (178 i). Large, monotonously dark blackish-brown, 



above without any marking. Beneath somewhat lighter, at the proximal margin of the forewing yellowish- 

 grey with traces of a darker postdiscal band. Hindwing ^ith 2 antemarginal, faded, lighter, dentate bands. 

 Panama (Chiric^ui), Hayti, St. Thomas, Cuba. 



64. Genus: Hesperia F. 



This genus being distributed across the whole world except Australia has been dealt with more at large 

 in the palearctic part. Briefly worded, the antennal club is rather obtuse, the palpi are erect, the second joint 

 clad with hair-scales, the terminal joint slender, obliquely upturned. Forewing with or without a costal fold, 

 posterior tibiae with 2 pair of spurs with or without hair-pencils. The homogeneousness of the American species 

 is still very uncertain; there are probabl}^ half a dozen .species at most. 



syricJitKS. 



a) With a costal fold and hair-pencil {Scelothrix Rmh.). 



H. syrichtus F. {= orcus Cr., oileus Ww., tartarus Hbn.) (178k) is extremely variable as most of the 

 other species. Above brownish-grey verging into black, particularly towards the base very much haired whitish- 

 grejr with white macular bands covering more or less the whole siu-face of the wings. Beneath the hindwing 

 is white with 2 irregular light grey or brownish dentate bands which are finely bordered with black, and with 

 high marginal bows. Most widelj^ distributed from Mexico to Paraguay, everywhere common. 



H. centaureae Rmb. {= wyandot Echo., ruralis Bsd.). This species figured in the palearctic part (Vol. I 

 t. 86 a) occurs also in the northern Atlantic States. The white spots are much smaller than in syrichtus, the 

 white hah'ing more scanty, beneath on the hindwing the bands are darker, more coherent. 



H. philetas Edw. resembles montivaga (178 k) above, but it has smaller spots. The hindwing beneath 

 is quite different white with a yellowish tint, basal and discal areas more whitish, without a discal band, scantily 

 streaked brown ; 3 small streak-spots at the costal margin are more distinct ; behind the middle are 3 rows of 

 most minute spots, the most proximal row only composed of small brown dots ; in the smoky brownish marginal 

 area minute, white moon-spots. Described according to a specimen from West Texas. 



.icripiara. H. scriptura Bsd. (178 k) is smaller than centaureae, the hindAving quite unspotted except a double 



white discal spot; frmges more purely white. On the forewing the submarginal macular band seems to be 

 more pointedh^ broken below the apex. California, Arizona. Montana.

H. bocchoris Heiv. The description of this Bolivian species was not accessible to us. 



H. fulvovittatus Btlr. resembles above americanus (179 b) except the more strongly smoked discal 

 band of the hindwing. Beneath the hmdwing is white with 4 orange transverse bands, an indistinct one at 

 the base, a verj^ irregular, oblique one behind the basal third, a curved, dentate one through the middle, being 

 here and there bordered with brown and being separated from a narrow marginal band only by a row of small, 

 white moon-spots; proximal margin broad white. From Chile.
