COLEOPTEEA 



Beet Carrion Beetle {SiJphabitubervsd Lee). During April and 

 ]\Iay this pest appeared in destructive numbers at many places in 

 the sugar beet district around Billings. In some instances young 

 beets were so badly injured that a very poor stand resulted and 

 in one instance wheat was attacked. 



Lesser Clover Weevil {PJiytonoDuii^ iiiorii-ostiis Fab.). The 

 first appearance of this insect in Montana was noted in the Jocko 

 Valley during the past season. This insect closely reseml)]es the 

 alfalfa weevil in appearance and the manner of its attack 1)ut is not 

 nearly as destructive. 



Eyed Elater {Alausociilatiis Linn). A specimen of this strange- 

 appearing insect was sent us from Custer. It is the first one to be 

 received into our collection. 



Bumble Flower Beetle (EnpliOTia inda L.). In the Yellowstone 

 A'alley this beetle was again reported as injuring corn by working 

 in the kernels at the tip of the ear. 



False Wireworm (Eleodes extricata var. convcvicollis Rlaisdell). 

 False wireworms were very abundant in many localities and in 

 several instances were injurious to newly sprouted grain. 



Cottonwood Leaf Beetle (Li/ia sci-ipta Fab.). During July and 

 August this was the insect concerning which there was the greatest 

 demand for information. Cottonwood and willow trees were attacked 

 in all parts of the State, \\niile this pest seldom kills trees outright, 

 it causes the foliage to turn brown and greatly weakens the vitality 

 of the tree. A drawing of the adult l:)eetle appears on the cover 

 of this publication. 



Dung Beetle (,lphodiiis inqjiiiiatufi Abst.). For the past two 

 seasons this insect has appeared in enormous numl^ers and has 

 attracted much attention. In the fall on warm, still days the air 

 frequently appears filled Avith the adults, and horse droppings are 

 Completely worked over in a few minutes. 



Wireworms {Ehderidde). Numerous reports of wireworm 

 injury were received during the course of the year, including injury 

 to potatoes, corn and grain.
