diate vicinity of distributing points for fruit or close to warehouses where 

 fruit is stored during the fall or winter, since the nDoths are almost sure to 

 be present at such points and warehouses. 



THE GOOSEBERRY FRUIT WORM— This insect is known to occur 

 in the vicinity of Missoula and Bozeman, and in these places it has been 

 doing serious damage. It is very probable that this insect is present in other 

 localities also. 



THE FALL WE'BWORM — The fall webworm was found by the writer 

 in an old orchard a few miles south of Missoula in August, 1900. It is a trou- 

 blesome species and attacks many kinds of trees besides fruit trees. Here 

 and there a limb in an orchard may be defoliated, or in worse cases, 

 whole trees may be stripped of their foliage. 



THE STRAWBERRY LEAF-ROLLER —This troublesome insect was 

 found in a garden patch of strawberry plants in the city of Helena. The 

 insect has a very bad name and would prove a very serious pest should 

 it become generally distributed. It occurs throughout Washington and in 

 that state is looked upon as the most destructive insect affecting straw- 

 berries. 



THE RED HUMPED APPLE-TREE CATERPILLAR— Specimens of 

 this insect were received from Mr. Bandmann in the summer of 1900. Presu- 

 mably they were taken in the vicinity of Missoula. We have little to fear 

 from this insect, since it is extensively attacked by an Ichneuman fly, which, 

 prevents its multiplying to troublesome numbers. The specimens received 

 from Mr. Bandmann were dead from the effects of this parasite. 



THE TARNISHED PLANT BUG — This insect is very abundant through- 

 out the state, feeding on a large number of wild and cultivated plants. In 

 the spring of 1900 specimens were received from the Bitter Root valley 

 with the report that the insect was causing extensive injury to strawberry 

 blossoms. The effected blossoms were blighted and failed to develop fruit. 

 It was also stated that the insect had caused injury in the same way in 

 previous years. In years past the insect has been reported as injurious to 

 young fruit trees in various parts of the state. 



This insect is native to the state, and we can never hope to exterminate 

 it, occuring as it does on wild vegetation. 



THE (BOX-ELDER PLANT-BUG — This species was sent to the writer 

 about the middle of September, 1900, from Park City, and was reported as in- 

 jurious to the fruit of the Silver prune. The insects settled in great num- 

 bers upon the trees, and, inserting their beaks into the partly ripened fruit, 

 extracted the juices. The effect upon the fruit was to give the surface 

 to the depth of about an eighth of an inch a somewhat corky appearance, 

 thereby ruining it. 



THE WOOLLY APHIS— We have had positive evidence of the pres- 

 ence of this insect in but one locality in the state. In September, 1899, Mr. 

 M. M. McDonald pointed out to me a single tree In the city of Missoula
