In P. viridisignata (Grote) the fore-wings are dark rosy-grey with numerous 
brown zig-zag lines. In the centre of the wing is an obscure bronzy-green figure, 
resembling a 3 or an 8 laid on its back. 
One of the finest insects in the genus is P. bimaculata (Steph.). In expanse 
of wings it measures an inch and three-eighths. Its fore-wings are rich rosy-brown 
variegated with dark markings and with a patch of chestnut red in the centre. 
In this patch are two golden spots, the upper somewhat resembling the letter v. 
I have noticed that the Eastern Township’s specimens of this moth are larger and 
brighter than the more northern specimens. 
- P. precationis (Guen.) is one of the most common species we have. Its 
fore-wings are of a rich purple brown with a golden sheen. They have a few 
pale wavy streaks, and a distinct silvery y in the middle of each. 
In P. simplex (Guen.) Fig. 24 the fore-wing is of a dark ash-grey. It has a 
brown apical dash, and a brown shade on the inner 
margin. This shade is separated from the ash-grey 
base and basal portion of the costa, by a fine white 
line, which joins the inner arm of the silvery y-like 
central mark. 
In P. falcifera (Kirby) the arms of the y are long 
and attenuated, and the tail lacks the terminal knob 
that is characteristic of Precationis and Simplex. 
Falcifera has rosy-brown fore-wingsstrikingly marked 
with curved and dentated rosy-white lines, having 
dark brown finer lines imposed. I captured several specimens of this insect at 
Como, P. Que. They were hovering over flowers on a sunny afternoon. 
P. brassicw (Riley, Ni Hubn) has been taken at Metis, P. Que. by Mr. 
Winn. This moth Fig. 25 expands 
about one and a half inches. It has 
dark greyish-brown fore-wings, with 
irregular, pale yellow cross lines, and 
in the centre a silvery w or horse-shoe 
like mark followed by an oval silvery 
dot. The underwings are yellowish 
clouded towards the outer edge. 
Of P. mappa (G. & RB.) only a 
few specimens have been taken in the 
Province of Quebec. The insect may 
be known by the numerous dark brown 
wavy lines upon its tawny fore-wings. 
In the centre of each of these wings is 
a silvery w, or horse-shoe-like mark, 
followed by a dot or annulet. 
P. U-awrewm (Boisd.) is a small 
species expanding one and one-fourth 
inches. Its fore-wings are dark brown, and bear in the centre a‘golden or silvery 
mark resembling a squat capital V. On the fore-wings also are several irregular 
transverse golden or silvery lines. 
Besides Balluca we have two species that have no metallic spots in the 
middle of the fore-wing, P. wrea (Hubner), and P. wreoides (Grote). In the former 
the wings are dark brassy-brown and in the latter, pale brassy-brown. Both 
have darker transverse markings. ®reoides has also, near the hind margin, a pale 
brassy transverse band.
