904 STAPHYLUS. By Dr. M. Draudt. 



funebris. S. funebris Fldr. (176 c) is somewhat similar, more blackish-brown with 2 distinct, coherent transverse 



bands which are particularly on the hindwing acutely prominent; the distal one is here towards the margin 

 bordered by a light grey stripe. Beneath lighter, red-brown, towards the margin on the forewing more yellowish- 

 brown; in the distal transverse stripe of the forewing there are here, more distinct than above, some small hyaline 

 spots proximally sharply bordered by dark. Mexico. 



corrosa. S. corrosa Mob. (= sericus Plotz) (176 c) is above blackish-brown with a violet reflection; one 



antemedian and one postmedian jet-black transverse Ime; in the distal one being very much ciuved there 

 are 3 white subapical hyaline spots and farther below two more; it is thickened into spots on the hindwing 

 at the costal margin, the proximal one on the forewing projects in the middle angularly towards the base, in 

 the cell of the hindwing angularly towards the margin. Beneath red-brown, marked as above. Mexico to Guiana. 



liiorius. S. liborius Plotz (176 c) is above not dissimilar; between the two transverse lines a third is mserted 



on the forewing. The small median hyaline spots are absent in the (^, whilst in the more greyish-brown $ they 

 are present. At the costa of the forewing there is another small hyaline spot at the proximal band; body and 

 base of wing show a greenish reflection. The under surface is more blackish-brown, in the anal half of the hind- 

 wing whitish. Bahia, Chapada. 



incisa. S. iticisa Mob. (= aserea Plotz) (176 c) is likewise similar, much smaller, darker, the 2 transverse 



bands broader, more faded, the proximal one on the hindwing reduced to a cell-spot. The forewing shows 2 

 white, subapical hyaline spots. Brazil. 



pulvenden- S. pulverulenta Fldr. (= taeniatus Plotz, zampa Ediv.) (176 e) is brownish-grey with a white-hyaline, 



"■ narrow median band distally projecting pointedly with 2 teeth on the median veins, whilst towards the costal 

 margin it is distally, towards the proximal margin proximally bordered with a ferruginous yellow; marginal 

 area especially towards the apex darkened. Hindwing in the disc and marginal area more extensively mixed 

 with a ferruginous yellow, with a lighter bluish-grey transverse line in the distal area. Beneath the hindwing 

 is almost white. From Arizona to Guatemala. 



emorsa. S. emorsa Fldr. (176 e) is a very variable species from Mexico, light greyish-brown, on both wings 



towards the proximal margin dusted bluish-white, with two whitish, partly hyaline macular bands and a very 

 large, roundish spot behind the cell. Beneath almost white, only towards the margin light yellowish-brown, 

 at the anal angle with a black spot. — At the same place and time there fly specimens with a very broad, purely 

 albimedia. white discal area on both wings and a more darkened base and marginal area: albimedia for^n. nov. (176 f), 

 without showing any real transitions, for which reason it may be a species of its oAvn. 



38. Genus: iitaphyliis G. d- S. 



It forms together with Bolla Mab. one of the most difficult Hesperid genera. Many species are externally 

 scarcely separable, at most bj^ slight differences in the length of the last palpal joint, the palpal covering or 

 other minute details, above all by the shape of the male genitals. The antennal club is somewhat obtusely 

 pointed, the thickening unilateral, so that the other side is concave. Costal fold present. The upper median 

 vein rises a little before the cell-angle. The distal margin of the hindwing is somewhat indented below the sub- 

 costal vein. The 3rd palpal joint is rather long, straightly porrect, the two first joints long-haned. The posterior 

 tibiae show 2 pair of spurs, no hair-pencil, but they are long-haired. We combine BolJa Mah. with it, the palpi 

 are here somewhat shorter, the hindwings more rounded. 



mazans. St. mazans Peak. (= ascalaphus Stgr., oeta Plotz, vincula Plotz) (176 f) is blackish-brown as all 



the following are, in some places particularly the 2 scantily strewn with somewhat lighter, yellowish scales, 

 with 2 very indistinct, broad, faded, darker transverse bands and 2 small white subapical dots on the forewing, 

 which may also disappear. The hindwing is in the cell and band-shaped behind it somewhat lighter spotted. 

 Mexico to Colombia and Venezuela, also in Trinidad, everyT^here very common. 



hayhursti. St. Hayhursti Edw. is very closely allied to mazans; the colour of the wings is decidedly lighter with 



a prominent dark marking, and below pinely white palpi which in mazans are intermixed with grey hair. It 

 maj' be the northern representative of ynazans from the southern United States, occurring, however, also in 

 Mexico. 



scoramus. St. scoraiTlus Schs. has the same shape of wings. Yellowish scales are interspersed into the ground- 



colour, the dark markings are almost entirely extinct; the scales form an antemarginal row of small, indistinct, 

 greenish yellow spots, the same in the disc and near the base; 2 small subapical dots are present. Beneath of 

 ■ a duller coloiu-iug, the small subtermii:ial spots a little more distinct, particularlj' on the hindwings. Palpi 

 dark grey. Expanse of wings: 26 mm. Peru. 



anginus. St. anginus Schs. (176 f) does not differ above from mazans. Beneath dark brown, the hindwing 



in the anal half thickly strewn with grey and with a white strigif orm spot at the cell-end. Expanse of wings : 

 21 mm. Novo Friburgo (Southern Brazil).
