Klougale, narrowly oval, riceoiis or dark reddisli- 

 browu, opaiine. Tlmrax sulnjuadrate, slijjlitly uar- 

 rowt-'il in front; sides feebly curved, margins rather 

 wide, retlexed, hind angles acute; surface, as well as 

 that of head, densely and granulately punctate. Ely- 

 tra nearly parallel, surface with rows of fine punc- 

 tures ; intervals finely and densely granulate. Length 

 14^17 mm. (Fig. 559.) 



Throughout the State; frequent. January 

 1-June 9. Both this and the next are introduced 

 species and live in granaries, storehouses, barns, 

 etc. Their larvffi are the "meal-worms" which 

 are apt to occur wlierever there is a heap of 

 grain remnants or debris. By removing or 

 changing such refuse their breeding places will be broken up and 

 the beetles kept in cheek. When its use is practical carbon bi- 

 sulphide will kill both larvae and adults.
