A. lunata Sm. (= albilunata 8m.) (40 e) is a small ochreous reddish species with whitish transverse lunula. 
lines and a white crescentiform reniform macula, the other maculae being absent; the veins of the central area 
are a little strewn with blackish; the undulate line is proximally shaded with dark, with internerval dots. 
Hindwing reddish-white, at the margin somewhat darker. California. 
A. erepta Grt. (40 e) is on the forewing ochreous, strewn with reddish, with brown-striped veins crc/tla. 
and red-brown transverse lines; the ring-macula in a whitish ring is fadedly bordered with red-brown, the 
reniform macula is a white crescent surrounded by dark brown; the red-brown undulate line is very indistinct 
and interrupted. Hindwing light yellow, at the margin brownish. Kansas. - - ryensis Bird (40 e) is of a variable rymst*. 
colouring, straw-coloured, more or less irrorated with a claret-colour and strewn with black; it chiefly differs 
in the absence of the ring-macula. Described from Rye, New York. — Larva diaphanous whitish, on each 
ring in front with a belt of purple brown colour, except the first and twelfth rings which turn paler with 
increasing growth. It lives on Tripsacum dactyloides. 
113. Genus: Axdiatocles Gn. 
Characterized by the absence of the proboscis, moderately long rising palpus with a short terminal 
joint, and a large hair-tuft on the frons, in the centre of which there is a horny pointed appendage; the thorax 
is clad with scales and hairs and exhibits a keel-shaped dorsal tuft of long scales; the abdominal tufts are large 
and besides there are lateral hair and a large anal tuft. 
A. zeae Harr. (= sandix Gn.) (40 f). Forewdng grey, irrorated with red. in the costal half darkened zone. 
by brown, at the base, in the cell-end and at the apex scaled fiery-red, with darker striped veins, indistinct 
dentate transverse stripes, the anterior one being double, the posterior one distally bordered with grey, with 
a double row of dots behind it; the small maculae are centred with brown; the undulate line consists of small 
yellow, red-striped spots. Hindwing light greyish-brown, at the margin lighter. Canada to Florida and Colorado. 
— Larva whitish with large lustrous black tubercles and shields; it lives on elder (Sambucus), not on maize. 
A. juanae Sch.s. (40 f) is darker red-brown, in the marginal area red-striped, with indistinct, finely juanac. 
crenulate transverse lines, the maculae surrounded with black, the reniform macula on the median somewhat 
proximally produced; the undulate line is composed of yellow dots. Hindwing much darker than in zeae. 
Mexico. 
A. metaleuca Dyar (40 f) looks very different: forewing quite light reddish-brown, at the apex with mctaleuca. 
a white spot from which a brown submarginal line proceeds, parallel to the distal margin; all the markings 
are quite extinct except the large rounded whitish maculae. Hindwing white. Mexico. 
114. Genus: Xantlioecia Hmps. 
Very closely allied to the Apamea, but separated by a pointed horny projection on the frons, the palpi 
being somewhat more porrect; the prothorax exhibits a large tuft in the shape of a trilateral pyramid, and 
behind it a bipartite tuft; the tibiae are long-haired, the abdomen only shows a basal tuft. The apex of the 
forewing is pointedly produced. Beside the palearctic X. flavago but one American species is known. 
X. buffaloensis Grt. (- latia Streck.) (40 f) is a large purple red-brown species, before and behind bulfalocnsis. 
the median area more purple grey, with darker striped veins, double transverse lines, the white maculae irrorated 
with yellow, the reniform macula in the centre with a curved yellow line edged with red, beneath divided into 
single small spots; the brown undulate line is dentate in the lower half. Hindwing yellowish, towards the margin 
irrorated with purple brown. United States (New York. Buffalo). — v. simplicissima Bird (40 g) has the maculae simpUdssi- 
coloured like the ground. Delaware. — The larva is diaphanous whitish with black tubercles and lives on 
Saururus cernuus, in the creeping root-stock and in the lower parts of the stalks, frequently changing the plants 
very quickly. 
115. Genus: Hydroeefa Dap. 
As has already been mentioned in Gortyna, the name Gortyna ought to be applied here. Very near 
to the preceding genus, but separated by the smooth frons and a loose, not parted tuft on the metathorax. 
Beside some palearctic species quite a number of American representatives have become known, the larvae of 
which also bore into the stalks and roots of mostly water-plants. 
X. serrata Grt. (40 f) is in the male recognizable by the long-combed antennae. Forewing light red, serraia. 
in the basal area intermixed with whitish, with feeble red transverse lines, only the subbasal line being double
