Insects of the Year. 

 Schizura concinna. 



The red-humped apple worm was very abundant during the 

 season, being reported from almost every section of the State. 

 A great deal of damage was done by them, especially to young 

 trees. Hundreds of trees set late last spring were stripped of 

 every leaf during the month of August. Of course these trees 

 would not leave out again during the season, and the chances 

 are that the most of them will not survive the winter. This pest 

 has been on the increase for several years but its parasites (See 

 page 176) were quite abundant this year and it is hoped that 

 they have got the better of it. Unfortunately the caterpillars 

 appear at just the wrong season of the year, when the orchardist 

 is not looking for any trouble from an insect invasion, and be- 

 fore he knows it the damage is done. The eggs are laid in a 

 cluster on the under side of the leaf. The young caterpillars 

 are gregarious in their habits, feeding together side by side on 

 the leaf. They grow rapidly and reach maturity in a few weeks, 

 disappearing as quickly as they came. They go into the ground 

 to pupate and remain in that stage until the next season. The 

 best way to get rid of them is to go over the trees when they 

 first appear and remove the leaf or cut ofif the twig that they are 

 on and destroy them by burning. 



Hemileuca maia. 



Colonies of H. maia have been located at Surry, Orland and 

 Fryeburg. Quite a number of the moths were sent in from 

 Surry and were supposed to be the brown-tail moth on account 

 of the reddish tuft at the end of the body. 



Caloso'ina scrutator. 



A fine specimen was taken at Seguin Light July 23rd. It was 

 crawling on the iron rail around the light; it was evidently 

 attracted to it the night before. 



Datana intigerrvma. 



September 7, in company with Mr. H. A. Jackson, I drove to 

 West Portland on the Buxton road about four miles from Port- 

 land. I found seven hickory trees from eight to twelve inches 

 in diameter and forty feet tall, completely stripped of leaves by 

 the above named caterpillar. As it was late, I found but few
