AMPLYPTERUS. By Dr. M. Dbaudt. 
gannascus. A, gannascus Stoll (= ganascus Hbn., rostralis Bsdv., daphne Bsd., sexoculata Btlr.) (96 c) is an extre¬ 
mely common and variable insect regarding the ground-colour and the extent of the dark marking. Light yellow¬ 
ish, reddish or violettish-brown, olive brown or chocolate brown spots; the basal oblique band may be 
broad or narrow, reaching the costal margin or not; mostly a lighter blotch behind the cell. The 3 black 
mollis, bands of the hindwing are often very broad and partly confluent. The extremest forms are: — mollis GeJilen 
(96 c). Forewing loamy yellow, with no marking except the very narrow blackish-brown subbasal band only 
extending to the cell, a small subapical spot and a small spot above the inner margin near the anal angle; the 
magicus. two exterior bands on the hindwing are confluent. From Sa. Catharina. — magicus Gehlen (96 c) is the re¬ 
verse of it, extremely large and very profusely marked, of a dark brown ground-colour. Hindwing red ba- 
rubra. sally, black distally with 3 rows of yellowish-white spots. Colombia. Other forms named are: — rubra Gloss, 
grisescens. a feebly marked form, the ground-colour turning more red-brown. — griseseens Gloss. Body and forewing 
fulvescens. silvery grey, from Icononzo (Colombia). - fulvescens Gloss, body and forewing reddish-yellow, from Orizaba 
acostalis. (Mexico). — acostalis Gloss, the dark subbasal band not extending to the costal margin, likewise from Mexico. 
interrupla. — interrupta Gloss. The black submarginal band of the hindwing is interrupted here between the veins and 
connexa. broken up into rhombic spots; Mexico. — connexa Gloss. The black bands of the hindwing are very strong 
cubanus. and confluent, so that the hindwing sometimes turns quite black. Sao Paulo. — cubanus R. & J ., from Cuba, 
jamai- has shorter and broader forewings. — jamakensis R. & J . is a large race with broad wings, the greyish cin- 
ccnsis. namon forewing with a broader subbasal band. Bands of hindwing narrow and situate more distally. 
The black spots beneath are almost extinct. Jamaica. 
dentoni. A. denfoili Clark (96 c) has narrower wings than gannascus and of a lighter grey colour, varying to 
whitish-grey; apex of forewing more produced, distal margin more convex, the subanal spot of the 
forewing is greatly reduced, the transverse linear marking more distinctly prominent; marginal area darken¬ 
ed brownish-grey, the dark spots more dark chestnut-brown, not olive. The black bands of the hindwing 
are broad. Peru (Chanchamayo). 
ypsilon. A„ ypsilon R. & J. (96 e). Body with a brighter red and green marking than in gannascus, wings 
broader; ground-colour variable, from yellowish-brown to deep carmine-brown. Subbasal band much 
broader and extending to the base especially at the inner margin, subapical spot also much larger, vein 6 brown 
in its entire length, marginal area extensively brown or olive. Shape of hindwing broader, median band scar¬ 
cely dentate, the two distal ones confluent except the costal-marginal portion where they comprise a red 
triangle of the ground-colour; marginal area behind them olive yellowish-brown, somewhat pink only towards 
the costal margin. Mexico to Ecuador. 
palmeri. A. palmed Bsdv. (= ganascus Wkr., marginata Btlr.) (96 d) chiefly differs from ypsilon in the sub¬ 
basal band being broadly interrupted in the cell, its costal-marginal portion being generally lighter brown, 
and behind it there is an oblique line extending to the centre of the costal margin. Hindwing with a broad 
blackish-brown marginal band. Separated beneath by the absence of the large black spots in the basal third 
of the forewing, by which the two preceding species are distinguished. Most variable. Brazil; Colombia; Peril; 
rubicunda. Venezuela. Early stages unknown. — ab. rubicund a Gloss is without discal bands on the hindwing, and the 
rubrimargo. black marginal band is very indistinct; very similar is: — ab. rubriniargo Gehlen, where the hindwing only 
shows the proximal one of the 3 bands, the two distal ones being scarcely traceable, the marginal area with 
flavellus. a yellowish tint. Brazil. — ab. fSavellus Gehlen has a red basal part of the hindwing, and the space between 
the median band and submarginal band is yellow; the forewing lacks the median spot between veins 2 and 3 
flavus. and the two small anal spots. 1 G from Novo Friburgo. — flavus Niepelt has an olive yellowish-grey ground¬ 
colour of the fore wings, and pale yellow hind wings with a slight pink hue, without the black marginal 
brasili- band, with traces of the interior band, without the median band. 1 G from Rio de Janeiro. — subsp. brasi- 
ensis. fietisls Clark (96 d) is of a lighter and more yellowish tint than western forms, and the red colour of the 
hindwing is lighter, and the dark marking on the forewing is duller. Rio de Janeiro. 
eury- A. eurysthenes Fldr. (= crethon Bsd., schausi Rothsch.) (96 e) is near to palmeri, but easily discer- 
sthenes. n ible by the non-interrupted olive green subbasal band of the forewing and the much less oblique antemedian 
line extending almost parallel to the subbasal band. Hindwing pink with 2 feeble discal lines and a broad 
blackish-brown marginal band. Espiritu Santo to Colombia. 
tigrina. A. tigrina Fldr. (97 a). Scheme of markings somewhat like that of gannascus, but the hindwings are 
straw-coloured. Forewing brownish tan-coloured, subbasal band interrupted, the upper portion distally re¬ 
moved, only an oval spot in the cell; vein 6 distinctly blackish-brown. Hindwing with distinct black veins and 
coronatu. 3 transverse bands. Venezuela; Colombia; Ecuador; Peru; Bolivia; South Brazil. — coronata Gehlen (97 a) is 
the race from West Colombia, distinguished by more intense whitish-grey dusting; the dark preapical spot 
assumes the shape of a crown the points of which show towards the base. The triangular subanal spots of 
the hindwing are enlarged. 
sexoculata. A. sexoculata Grt. (= depuiseti Obth.) (97 a) looks like a very dark gannascus, but is structurally dif¬ 
ferent like tigrina by the spined anterior and middle tibiae. Forewing dee]) chocolate brown, quite similarly 
marked as gannascus. Hindwing pinkish-red in the basal half, more yellowish orange distally, veins very 
thick, distally widened blackish-brown. Venezuela; Colombia; Ecuador; Peru; Bolivia.
