where during 1924. This insect alone is doing much to prevent the 

 growth of currants in Montana. 



The Cherry Fruit Fly (Rhagoletis cingulata Loew.) The cherry 

 fruit fly was found in (he northwestern part of the State in 1923. 

 While it has not done great damage, so far as has been reported it 

 may at any time be a pest of some prominence. 



The White-Winged March Fly (Bibio albipennis Say). The 

 larva of a March fly appeared in unusual numbers in gardens in 1924. 

 In previous years it has been found in great numbers in sweet pea 

 trenches and in garden tracts. 



The Cabbage Maggot (Phorbia brassicae Bouche). This pest on 

 the roots of cabbages was reported during 1923 as doing some damage. 



The Beetj.es (Coleoptera) 



Ground Beetles (Carabidae). We received reports of an undeter- 

 mined species of this family of beetles injuring the ripened fruit of 

 the strawberry in 1924. 



The American Kaspberry Beetle (Byturus unicolor Say). We re- 

 ceived our first information of the presence of this pest of raspberries 

 in the spring of this year, though the species has been present for 

 some years in the locality reported, namely, near the southern end 

 of Flathead Lake. It is a persistent and injurious species, objection- 

 able especially because of the danger of shipping the grubs in the 

 fruit when it goes to market. 



Wireworms (Elateridae.) Almost every season sees some wire- 

 worms somewhere in Montana. The season of 1924 was notable for 

 the prevalence of wireworms in potatoes and garden crops in Montana. 

 Extensive damage was done by these insects boring through the tubers 

 and rendering them unfit for sale. The species concerned has not been 

 determined. Some trouble was also reported with wireworms in wheat 

 and in corn. 



The Flea Beetles (Epitrix subcrinita LeC. and Psylloides punc- 

 tulata Melsh.). These minute, jumping beetles were again reported from 

 gardens generally in the Slate in 1924. having injured numerous gar- 

 dens as the seedling plants were just coming up. 



The Three-Spotted Flea Beetle (Disonycha triangularis Say). 

 This large flea beetle is apparently on the increase. It was received 

 several times during 1923 and reported as injurious on various garden 

 I hints, particularly beets and spinach.
