GERRA; GERRODES; AUCULA. By Dr. M. Draudt.

L. noa Dyar. Above quite black with white fringes. Beneath the proboscis, palpal base, the base of noa. 
the forewing and the basal half of the costa of the hindwing are orange; 43 cm; Zacualpan, in September, type 
in the National Museum at Washington. 
20. Genus: (ilirra Wkr. 
Distinguished by obliquely rising palpi, the 2nd joint of which shows beneath long, beard-like hair; 
the 3rd is short. The frons exhibits a large, rounded projection with a coniform crest in the middle and a horny 
plate below it; £ antennae with moderately long pinnae, in the $ serrate. Tibiae with long hair. Neuration 
without any differences. 
G. radicalis Wkr. (= adrasta Drc.) (1 i). Forewing chocolate-brown, strewn with silvery blue scales, radicalis. 
maculae bordered with red-brown; a posterior, finely dentate transverse stripe is likewise red-brown, distally 
bordered with yellowish-brown and proximally accompanied by a purple-brown dentate line. Hindwing orange 
with a black marginal band. Mexico. 
G. sevorsa Grt. (= aedessa Drc.) (1 i) resembles the preceding, but it has a whitish costal-marginal sevorsa. 
spot behind the reniform macula and a less blue reflection; beneath there is, as in radicalis, a broad, orange, 
postmedian oblique band. The nomenclatural type originates from the United States (Arizona). The southern 
form: meridionalis nom. nov. exhibits besides beneath in the cell another, quadrangular, yellow spot and flies meridiona- 
in Mexico and Guatemala. 
G. aelia Drc. (5 b) is above scarcely discernible from sevorsa, the ground-colour of the forewing is aelia. 
perhaps somewhat duller greyish-brown, the orange of the hindwing more intense, the marginal band of it 
broader; beneath the oblique band behind the ceil is white. Panama, Costa Rica. 
G. brephos spec. nov. (1 h) likewise greatly resembles sevorsa : forewung more grey strewn with lustrous brephos. 
bronze scales; the reniform macula is in a rectangular line towards the proximal margin, in sevorsa towards 
the costal margin; the dentate posterior transverse line is more distinct, extends parallel to the border and 
does not make a bend round the reniform macula. Beneath only an orange postdiscal band, the $ is without 
the square cell-spot. Described according to 2 fresh couples from Mexico (Zacualpan) taken in July (type in 
Coll. Draudt). 
G. sophocles Dyar (1 h) shows rather hazy colours, on the forewing blackish-grey, scantily strewn sophocles. 
with silvery scales; the maculae and 2 postmedian dentate lines are red-brown, behind the reniform macula 
an oblique, whitish patch. Hindwing black with white fringes. Body black, collar, shoulders, thoracal sides 
and the bases of the wings beneath orange. Mexico (Guerrero). 
G. pulchra spec. nov. (1 h) has more extended forewings with a more oblique distal margin: purple- pulchra. 
grey intermixed with silvery grey scales; the costal margin and numerous dentate, very oblique transverse 
lines of a deep red-brown, the postmedian line encircles, twice flawed, in a large bow the red-brown, silvery 
grey pupilled reniform macula behind which there is faint yellowish patch. Hindwing orange with a blackish- 
brown marginal band particularly broad towards the apex. Forewing beneath with a postdiscal orange oblique 
spot. Described according to a from Mapiri (Bolivia), but there axe also numerous specimens from Colombia 
(Pacho, Muzo, Rio Negro) from the Coll. Fassl. 
21. Genus: CJerrotles Hmps. 
Distinguished from the preceding by its ciliated antennae, haired thorax with a hair-tuft on the meta- 
thorax. On the abdomen only the basal segment shows a tuft, in Gerra the first 4 or 5 segments. No difference 
in the neuration. Only 2 larger species: 
G. longipes Drc. (1 k). Forewing brown, in the marginal area more grey. The fine, dark brown post- longipes. 
median line is in the upper part parallel to the border, in the lower it is double and runs parallel to the costal 
margin to the base of the proximal margin; another fine, dentate line before the border; at the costal margin 
another oblique, lighter subapical patch. Hindwing orange, with a black marginal band. Mexico. 
G. minataea Dyar (= longipes Holl.) (1 k) is very similar, easily discernible by a still lighter dove- minataea. 
coloured border and proximal margin; the postmedian line is, particularly in the lower part, broadly bor¬ 
dered with white. United Staates, Mexico. 
22. Genus: Aueula Wkr. 
Distinguished from the two preceding genera by a somewhat longer, porrect 3rd palpal joint, the thorax 
and abdomen without tufts, and the upper radial of the forewing rising from below the upper cell-angle.
