193 



This snout^beetle (Fig. 193) is about a fifth of an inch long, red to 

 pitch-brown, rough-surfaced, but somewhat shining. The thorax is 

 nearly globular, and the part of the ])ody bcfiirifl the thorax is oval. 

 The beak is short, broad, and flattened. 



We have found the beetle frequently in bhi(!-grass, on apjjlo loaves, 

 on wheat, and at the roots of pumpkin. At the Michigan Agricultural 

 College, the larva3 were found in May 

 and June girdling the crowns of straw- 

 bcrricis. These were reared to the adult 

 by Mr. C. M. Weed, who published a full 

 account of the species.* Similar injuries 

 to the strawberry have been reported from 

 Massachusetts and Minnesota. In Illinois 

 it has lately been found eating straw- 

 bei-ry roots. The adult is said to have 

 done serious damage to cabbage and 

 shrubVjery in New York, and it has been 

 taken feeding on rose leaves and h)orage. 



According to Mr. Weed, the larvae 

 found in May and June were full grown 

 fiom the middle to the last of June. The 

 ]mpa is formed in an earthen cocoon in 

 the soil near by, and the adult emerges 



eight or ten days later. The stages overlapped, however, so that all 

 three could be taken at the same time. Our collection contains exam- 

 ples of the adults taken from March to the middle of August, and also 

 in October. Probably there is but a single brood, the species hiber- 

 nating in the beetle, and possibly also in the larval, stage. 



The species is a native of Siberia and Europe, whence it has invaded 

 this country, and is now widely distributed in the United States and 

 Canada westward to the vicinity of the Rocky Mountains. It is common 

 in the J^ast, but not especially so in Illinios.

LiMNOBARIS DEPLANATA Casey. 



A single example of a small, slender, dark gray snout-beetle, about 

 an eighth of an inch long, was found at Urbana September 18, by an 

 assistant of this office, behind a corn leaf-sheath at the s(;cond joint 

 above the ground. Numerous small )>injctures of the form usually pro- 

 duced by snout-beetles — o}>ening into small cavities but not perforating 

 the leaf-sheath — were found at this point, doubtless the work of this 

 beetle. It agrees faii'ly with Casey's d(;scripti(jn of deplanata, but is 

 possibly an undescribed species.
