of this species were clustered in lumps of from five to 20 ; they 

 broke to pieces almost at a touch and the enclosed pupae fell out. 

 The moth itself measures about an inch across the expanded wings, 

 the front ones are pale brown in colour, and mottled with darker 

 brown and grey, the hind wings are almost white, with brown 

 shadings towards the edges, the ribs (or veins) are brown, and the 

 outer fringe of hairs is white. The egg is small, clustered on the 

 bark, sometimes they are laid in rows, or occasionally scattered 

 here and there. 



There are several parasites that destroy the larvae, the most 

 plentiful being a moderately large Chalcid wasp, there are also two 

 species of Ichneumon, and several flies. 



Remedy. Use No. 16. 



CUT WORMS. Various species of Agrotis are related genera : 

 soft brown or gray worms of various kinds ; feed upon the roots, 

 crown, or tops of plants. Some come out at night and eat. They 

 curl up when disturbed. Most of them feed upon grass when 

 young, becoming about half grown by winter time, hibernating in 

 the soil, and coming forth in the spring in search of food. They 

 pupate late in the spring, and three or four weeks later emerge as 

 moths. Some species have several broods in the season. 



Remedies. Bait poison, No. 16. Caution : Great care must 

 be taken that fowls and stock do not get at the bait. 



THE GRAIN MOTH (Gelechia cerealella, Linn.). 



This pest is very destructive to stored wheat and corn, especi- 

 ally to the former. It eats out the interior of the grain, leaving 

 nothing but the empty hull. A single grain furnishes sufiicient 



food for a larva from 

 the time it issues 

 from the egg until it 

 becomes fully grown. 

 It assumes the pupa 

 form within the grain 

 or hull. The per- 

 fect moth has the 

 head of a dull ochre 

 colour, the fore wings 

 pale shining ochre, 

 with greyish or 

 brownish streak at 

 the base of each wing, 

 the hind wings are 

 also greyish ochre.
