Size of paludicola. All the insect is of the colour of I'ush or dry reed. Body 
hairy, uniform, and without spots. Anterior wings oblong, rounded at the hinder 
margin ; the only markings are a series of little blackish-grey dots on the nervures in 
the place of the elbowed-line, a dot at the apex of the cellule, and sometimes 
another on the sub-median vein near the base ; sometimes the nervures are more 
or less powdered with grey ; fringe concolorous, without dots : inferior wings almost 
concolorous above, but paler beneath, without markings. Antennce with robust, 
hut small, laminae. I have only seen the male. 
N.B. — It is scarcely possible that this can be Leueania unica, 
Walker, p. 112, in which the anterior wings are without spots, and the 
abdomen much paler than the thorax. 
Family hi. APAMID^. 
Genus Altsia, Guenee, nov. gen. 
Antennae of the ^ long, crenulated, each crenulation carrying a 
tuft of hairs at the tip, and a longer one in the middle ; those of the 
$ cylindrical, pubescent, each joint carrying two longer hairs. Palpi 
thick, ascending, robust, hairy ; the third joint very distinct, scaly. 
Haustellum small, robust. Thorax broad, somewhat depressed, quadrate, 
strongly hairy, but not bristly ; breast very hairy. Abdomen of the 
^ long, smooth, silky, not crested, laterally hairy, not conical ; that of 
the $ conical, thick, and hairy. Legs robust ; the tarsi with spines. 
Wings oblong, thick ; the superior slightly prolonged at the apex ; the 
inferior sinuated at the hinder margin. 
A genus of a very ambiguous aspect, and oscillating between the 
LeucanidcB, Apamidce, and Noctuidce. At first sight it resembles Xylo- 
phasia, but the non-crested abdomen, unicolorous palpi, &c., will not 
permit its being united to that genus. Not knowing the earlier states, 
and being able to examine only one imperfect female, I place it pro- 
visionally after Luperina ; but it will not be astonishing if, hereafter, it 
shall be transferred to another position in the Apamidce, or even in the 
LeucanidcE. I direct attention to the structure of the male antenna).
