divided in black and yellow. There is a conspicuous yellow 

 "W" on the center of the anterior portion ; one-half of the letter 

 on each elytron. The legs are light yellow. 



The female lays her eggs about the middle of July in the 

 crevices of the bark. These hatch and the young larvae work 

 their way through the bark into the sapwood. Here they 

 remain cutting their way around the tree or in irregular gal- 

 leries up the trunk, thus sapping the life of the tree. The time 

 to destroy them would be in the spring before they have worked 

 into the wood. Look for the sawdust-like casting and with a 

 sharp knife hunt them out and destroy them. A wire may 

 sometimes be used to great advantage in tracing their course 

 in the wood. 



Plate V shows the gallery in a maple stick where the pupa 

 hibernated during the second winter before emerging as a per- 

 fect insect. This gallery was made by the larva. The adult 

 beetle is shown in the corner. 



INSECT MOUNTS. 



A good deal of pains was taken to collect enough material to 

 put up some mounts showing the life history of the brown-tail 

 moth. It was rather a disagreeable undertaking to secure 

 enough full grown larvae to inflate for this purpose, as it neces- 

 sitated the handling of several hundred specimens. This 

 required a great deal of painstaking care and as a result those 

 who did the work were bountifully paid for their endeavors by 

 having all the brown-tail rash that could very well come to them. 

 All of the men in the field were fortunate ( ?) enough to enjoy 

 all of the comforts and some of the discomforts attendant upon 

 such an investigation. Many brown-tail caterpillars were found 

 in company with the gipsy larvae under the burlap. It was a 

 much easier task to secure the pupae, moths and egg-clusters; 

 these last were collected in Kittery and York where they could 

 be found in abundance on the leaves. 



About two hundred were obtained and have been arranged 

 in suitable mounts for educational purposes. A set comprises 

 an egg-cluster deposited on a leaf of the food plant; a winter 

 nest; an inflated full grown caterpillar; a pupa, the resting
