This is a very common species. I have an enormous series, 
taken ‘at different times and places. There is not a shadow of 
doubt in my mind that the above synonymy is correct. The 
females are very variable upon the upperside of the wings, but 
agree very well with the males on the underside, though in both 
the male and the female sex the silvery centres of the spots on the 
underside are often suffused with dark brown, and the silvery 
colour is rendered obsolete.

I allow this species to remain in this genus, to which it has been 
assigned by its author, though it is quite plain to me that it does 
not really belong here. I have the type before me as I write, but 
“as it is unique and in poor condition, so that I cannot without 
great risk of further injury make a close anatomical investigation, 
I must ieave its location undecided. It seems superficially to show 
a general relationship to pulvina, Ploetz, and nox, Mab., but the 
wings are more fragile and relatively longer, and the insect is not 
so robust.

_ A figure of the type kindly lent me by Mons. Mabille suggests 
that this is the female of Semalea pulvina, Ploetz (q.v.). It is 
certainly not a Cobalus, as that genus is South-American. 
ANDRONYMUS, gen. nov. 
Antenne more than half the length of the primaries, slender; 
club moderate, fusiform, slightly recurved at the tip. Palpi 
divergent, with the first and second joints heavily clothed with 
seales, the third joint naked, aciculate, erect, as high as the vertex 
of the head. Fore wing elongated, with the inner margin con- 
siderably longer than the outer margin, blunt at the apex, and 
slightly excavated between the extremities of veins 1 and 3. Cell 
narrow, elongated, nearly two-thirds the length of the costa; vein 
12 reaching the costa betore the end of the cell ; upper discocellular 
short, but distinct, at right angles to the upper margin of cell ; 
middle discocellular relatively long, curved inwardly ; lower disco- .
