MONOGRAPH OF THE GENUS SAPERDA 21 



Saperda mutica Say 



Life history. Very little is recorded concerning the life his- 

 tory of this species. Beetles were taken by Mr W. H. Harring- 

 ton on May 15 and captured by him in the open on June 29. He 

 records this species as living on decaying willow. 



Distribution. This beetle has been recorded from the follow- 

 ing localities: Missouri [Say], Buffalo [Zesch-Reinecke] , New 

 Jersey [Smith], Ottawa Can. [Harrington], Canada, New York, 

 New Jersey, Missouri, Kansas and Nebraska [Leng-Hamilton] , 

 Philadelphia Pa. [Wenzel]. Dr LeConte thought that this species 

 was probably the S. populnea of Fabricius and Olivier. Its 

 work is unknown to us. 



Description. Black, sparsely covered with a gray or fulvous 

 vestiture which is denser in places, forming numerous spots on 

 the elytra [pi. 7, fig. 2]. These denser places are usually yel- 

 lower in color. Antennae short, annulate, with first joint enlarged. 

 Thorax narrowed in front with a fulvous line on dorsum, con- 

 tinuing on the head, also lateral line on sides. Head impressed 

 in front between the eyes.
