Small, slender, elongate forms, having the prosternum pointed 

 behind; the scutellum transverse and acuminate. The larva' live in 

 slender stems and twigs of shrubs and trees, and often do much 

 damage, especially to blackberry and raspberry canes. The genus 

 has been monographed by 



Born. — "The species of Agrilus of Boreal America," in Trans. 

 Amer. Ent. Soc, XVIII, 1891, 277-33G, PI. VIII. 



In this paper Horn recognizes 51 species, 18 of which have been 

 taken in Indiana, \\ hile several others doubtless occur. On account 

 of the large niimber of species the Indiana members of the genus 

 are classed in three groups.
