PYRALIDJE.—Snout Moths. 
The common name is given to this family on account of the long, 
slender, compressed palpi, and by this character they may usually be 
known. The wings vary somewhat, but in the most of them the ‘fore 
wings are triangular, and when the moth is at rest, they form to¬ 
gether a triangle resembling the Greek letter Delta, w’hence they are 
sometimes palled Deltoids. The antennae are sometimes simple, at 
others pectinate in the males, or hair} 7 . The legs are rather long and 
slender, the front pair often tufted. The moths are to be found in 
moist grassy places; are readily disturbed bv day ; mostly flv in early 
twilight, while some are true day flyers. Only those few injurious 
species that may be met with in the State, will be mentioned here. 
TIypena humuli, Harris.—The Hop-vine Moth. 
I have not seen this species or its work for several years, hence will 
draw largely from the matter of others for my use here. Rev. C. J. S. 
Beihune, in the Report of the Ontario Entomological Society for 
18/2, says of this, “In the month of June, earlier or later, according 
to the season, the hop grower may frequently observe the leaves of 
many oi his vines riddled "with holes, or eaten down to the ribs. On 
inspection he finds a small caterpillar at w 7 ork, pale green in color, 
with a dark, almost blackish longitudinal stripe on the back, and two 
narrow white lines on each side. Sometimes these lines are wanting. 
The body is long and slender, with its rings or segments very promi¬ 
nent ; each segment is furnished with two transverse rows of black 
dots, irom each of which proceeds a short hair. The head is rather 
deeply divided into two lobes, and is covered with similar dots and 
hairs. The mouth is yellowish, with the jaws tipped with black. Un¬ 
like the majority of caterpillars, this creature is furnished with only 
seven instead of eight pairs of legs, being destitute of the first pair of 
prolegs beneath the middle of the body. The result of this deficiency 
is that the caterpillar is obliged to loop itself up to a slight extent 
when crawling, though not to the same degree as the Geometer or 
measuring worms. When fully grown, it is over half an inch in 
length. It is a particularly active creature, and when disturbed jerks 
its body from side to side, and leaps from one spot to another; it is 
also able to let itself down from its leaf by a fine silken thread. After 
it has attained to maturity, it descends to the ground, and crawling 
into any device or other place of concealment, forms a slight silken 
cocoon and changes into the chrysalis state. In this condition it re¬ 
mains for a fortnight, or three weeks, and then comes forth at the 
end of .June or early in July, as a dusky brown moth, measuring an 
inch and a quarter across its expanded wings. The fore wings are
