NOCTURNAL LEPIDOPTERA FOUND IN CANADA. salle. 
Gen. Carocara. Ochs. 
Size large. Body stout. Palpi thick, pilose obliquely ascending, 
moderately long; their third joint very distinct, short. Antennze 
slender, pubescent in male, setaceous in female, more than half the 
length of the body. Thorax convex, thickly pilose. Abdomen crest- 
ed, generally extending beyond the hind wings. Legs lon’, stout, 
very pilose. Wings large, slightly denticulated. Fore wings almost 
invariably gray, clouded with black and white; slightly convex along 
the costa, angular at the tips, moderately oblique on the exterior mar- 
gin; the markings constant in almost all our species are, first, a series 
of dark points set off with white, close to the exterior margin; then 
the submarginal line, which is seldom clearly defined ; the two follow- 
ing lines, however, are usually very distinct, and distant from each 
other: the inner line being composed of lunules or irregular arcs, the 
elbowed of teeth more or less sharp ; of the two spots, the reniform 
is the only one visible, though it also is frequently much obscured; a 
third immediately belind it, called the subreniform, is more commonly 
apparent, being clearer than the others, and edged with black. Hind 
wings denticulated, crimson or luteous, with a black band and a black 
border, rarely wholly black, or black with a white band.
