AMPHIPYRA; MAGUS A. By Dr. M. Draudt. 
Papaipema, as well as the llydroecia. Beside the Apatela, we have furthermore already dealt with another small 
part of the genera beginning from Xerociris (cf. p. 8) to Psyc-homorpha , which on the one hand are closely 
allied to the Amphipyrinae, but which on the other hand exhibit close relations — also biologically by the 
larvae living on Vitis — to the Agaristidae. 
1. Genus: Ampliipyrsi 0. 
Proboscis developed, the erect palpi are moderately long, the frons is smooth; the thorax is covered 
with hair and hair-like scales, without tufts, the abdomen is flattened, laterally hairy. This chiefly palearctic 
and Indo-Australian genus is also represented in America by 3 representatives. (Cf. Vol. Ill, p. 158; Yol. XI. 
p. 118). 
pyramidal- A. pyramidoides On. (30 a) is distinguished from the extremely similar palearctic pyramided (Vol. Ill, 
cJes - pi. 38 a) by its somewhat smaller size, more distinct macular marking, and the obliquer course of the postmedian 
inornata. line in its subcostal part. — inornata Grt. has more darkened hindwings, on which the disc remains copper- 
conspersa. reddish. — conspersa Riley is intensely strewn with grey, with almost extinct markings. Very widely distributed 
from Canada to Mexico, and mostly common. •— The green larva with a white dorsal stripe and an interrupted 
lateral stripe, exhibits a pointed protuberance on the I2tli ring and lives on foliage-trees. 
tragopogi- A. tragopoginis L. (= repressus Grt.) is a very common species, being also distributed in the palearctic 
ms. re gi ons ( c f y 0 p JU ? p. 159 , pi. 38 d). Forewing greyish-brown with a greasy lustre, with 2 or 3 small black 
discal spots. From Canada down to New York. •—- The green, posteriorly somewhat raised larva lives on low 
plants. 
glabella. A. glabella Morr. (30 a) is much lighter greyish-brown, in the terminal area more whitish with 
indistinct double transverse lines, a blackish ring-macula and a whitish reniform macula, the latter below 
with 2 black dots. Hindwing light brownish, towards the margin darker with a whitish marginal band before 
brunneoa- the black marginal line. -—- brunneoatra Strd. (= ab. 1 Hmps.) has the forewing more intensely huecl with brownish- 
ira - black. Pennsylvania to California and Arizona. 
problemati- A. problematics sp. n. (30 a) corresponds with the diagnose of this genus except the abdomen not being 
ca - flattened. A large species with a light reddish-grey forewing with a slight greasy lustre, finely irrorated with 
a darker colour, with brownish-grey crenulate transverse lines, the subbasal line extending to the submedian 
fold; instead of the coniform macula a very slight projection; the upper maculae are medium-sized, encircled 
with a plain brownish grey, the ring-macula horizontally-elliptical, at both its ends somewhat pointed, the 
reniform macula being concave towards the margin is below distally not defined; the undulate line is scarcely 
noticeable as a very indistinct darker shading; before the light basal line of the fringes there are black marginal 
dots. Hindwing whitish, margin and veins brownish. According to 1 $ from Peru (Coll. Seitz) in the Sencken- 
berg Museum at Frankfurt o. M. 
2. Genus: Magusa Wkr. 
This genus is represented in America by but one species with narrow and long wings. The structure 
is similar to the preceding genus, but the thorax is chiefly covered with scales and exhibits a feeble, twice keeled 
tuft; the S anterior femora bear hair-tufts, the abdomen has a tuft on the first rings. — The only American 
species of the genus Magusa is hardly generically to be separated from the Indian genus Sasunaga Mr. (cf. 
Vol. XI, p. 119), one species of which, tenebrosa Mr. (Vol. XI, pi. 15 c) is wide-spread and very common in 
quite a number of entirely heterogeneously coloured forms. — In Africa there is the genus Gallixena Saalm. 
which, consisting of the only species versicolora Saalm., has recently also been ranged in the genus Magusa. 
orbifera. M. otbifera Wkr. (= divaricata Grt., discidens Fldr., sarpida Fldr., angustipennis Mschlr., divida 
Mschlr.) (30 a) is a most extraordinarily variable insect, the type of which is red-brown, darker irrorated, with 
black marginal streaks, indistinct double transverse lines filled up with grey, the distal line of which is proximally 
and distally shaded with grey; the maculae are finely encircled with black; before the light undulate line at 
the costal margin a black spot, behind it mostly lighter. Hindwing blackish-brown with a dark coppery reflection, 
basally scantily scaled, with light fringes. In the $ the hindmarginal area is light grey, the costal-marginal 
orbijerclla. half red-brown. — In the form orbiferella Strd. ( = ab. 1 Hmps.) (30 a) the forewing is dark brown, submedianly 
orbiferana. irrorated with whitish at the transverse lines and at the costal-marginal part of the undulate line. — orbiferana 
Strd. (= ab. 2 Hmps.) (30 b) has a light reddish-brown hindmarginal half, the costal-marginal half being 
perversa, irrorated with black. — perversa Strd. (= ab. 3. Hmps.) (30 b). Like in the typical $, the hindmarginal half 
strigifera. below the submedian fold is grey, distally expanding, but the costal part is not red-brown. — strigif era Wkr. 
likewise resembles the normal $, but all the markings are bordered with grey. New York to Argentina and 
the West Indies. — The light green, white-striped larva lives on Condalia ferrea.
