NAGIDUSA; ELLIDA; FENTONIA. By Dr. M. Draudt. 
lintneri. G. lintneri Grt. (154 a) is a somewhat larger species for which even a special genus, Eumelia Neum. 
<£• Dyar, was established. Forewing ash-grey or mouse-coloured, with black transverse lines, the anterior one 
straight, not curved, and with an indistinct cross-vein streak; median area and a smal 1 basal spot loamy 
yellow, small yellow black-scaled submarginal spots. Hindwing just as dark as forewing with a distinct post- 
avimacula. median line and a lighter shadow behind it. — f. avimacula Huds. has also an ash-grey median area, only 
intermixed with some yellow scales at the border-lines, containing a dark median area, and a very distinct 
yellow reniform macula surrounded by black is at the cell-end, the basal spot below the cell is also yellow 
slossoni. surrounded by black. — f. slossoni Pack, is lighter ash-grey, the basal fifth blackish-brown, the two yellow 
severa. spots of avimacula are whitish-grey here. — f. severa Edw. is a large strong form with a broad blackened 
median band and the yellow spots of avimacula. Hindwing with a blackish median band with a lighter filling; 
danbyi. this form flies in California — f. danbyi Neum. is a large, very light yellowish loam-coloured form with a 
scarcely visible lighter median area and feeble transverse lines; the reniform macula is also very fine and 
normalis. indistinct. California. — f. normalis Dyar is smaller than the preceding forms, the median area yellowish, 
a very narrow grey tinge on the averted sides of the transverse lines; reniform macula very distinct, filled 
with grey. — The larva is diaphanous light green with a yellow lateral line and lives on Pop ulus tremuloides 
and balsamifera. 
108. Genus: Nagidusa Wkr. 
Antennae of $ pectinated to the tips, of $ plain; a small tuft on the head. Forewing long and narrow 
with an oblique margin and a rather pointed apex; as in all the neighbouring genera it lacks the areoh, 
vein 5 arises above the centre of the cross-vein, 6 is stalked with 7—9. Hindwing as in Gluphisia. Few tropi¬ 
cal American species. 
Type of genus: N. xylocampoules Wkr. 
xylocam- N. xylocampoides Wkr. (= exyra Drc.) (154 a) is a large species with light brown forewings strewn 
poides. with grey, with a large quadrangular grey costal-marginal spot and a few small dark brown costal spots 
near the apex. Hindwing white, yellow at the inner margin with a brown marginal line. Venezuela. 
cinescens. N. cinescens Schs. (= miranda Dyar). Forewing grey with fine undulate double black mostly indistinct 
transverse lines and a dark cell-end streak; an indistinct subterminal shadow, with black vein-streaks and 
internerval streaks towards the costal margin; fringe speckled dark. Hindwing smoky grey with a whitish 
postmedian line. Expanse of wings: 47 mm. Mexico, Arizona. 
suavis. N. suavis Dyar (154 a) is smaller and more slender than the preceding species, fore wing violet bluish - 
grey, strewn with yellowish ochre and red-brown at the costal margin, with red-brown double transverse lines 
filled with yellowish-ochre, the cell-end macula of the same colouring. Hindwing whitish, fringe greyish-brown, 
with brown apical lines. Mexico. 
mycomba. N. myconiba Dyar is also similar, greyish-blue, abdomen black; forewing strewn with black, with 
double indistinct transverse lines, the posterior one shaded dark behind the cell and above the inner margin; 
the undulate line is composed of large faded spots between the fine black veins of the marginal aiea. Hind¬ 
wing brownish-grey with a light median line at the costal margin and inner margin. Expanse of wings: 42 mm. 
Mexico (State of Hidalgo). 
109. Genus: Kllida Grt. 
Like the preceding genus, but the origin of vein 5 of forewing is removed down to the centre of 
the cross-vein, and veins 3 and 4 of the hindwing arise from the same base, not separately. Only one North- 
American species: 
Type of genus: E. caniplaga Wkr. 
cuniplaga. E. caniplaga Wkr. (= transversata Wkr., gelida Grt.) (154 b) is monotonously ash-grey with a contrast¬ 
ingly brown head and collar, the focewing with 3 distinct antemedian transverse lines, the outermost of 
which extends close to the brown discal spot; 2 indistinct postmedian lines are marked by vein-dots, a sub¬ 
marginal row of small irregular brown spots. Hindwing dark ash-grey. Larva unknown. Canada, New York, 
Maine. 
110. Genus: Feutoitia Btlr. 
Separated from Ellida only by the antennae being pectinated not quite to the tips, and by somewhat 
longer porrect palpi. Forewing somewhat broader, no difference in the neuration. The genus, also known as 
Macrurocampa Dyar, contains beside a number of Eastern Asiatic species also 3 American species, two of which 
occur in North America. 
Type of genus: F. marthesia Or.
