Tribe IV. ENCYCLOPINL 



In this tribe the head is quadrate, sud- 

 denly but not strongly narrowed and con- 

 stricted far behind the eyes so that the neck 

 is very short; eyes finely granulated, 

 obliquely emarginate ; antenna? 11-jointed. 

 the first five joints punctured; thorax con- 

 stricted before and behind, wider at base, 

 tuberculate on sides, scutellum small, tri- 

 angular; elytra elongate, parallel rounded 

 at tips ; legs slender, hind pair longer, first 

 joint of hind tarsi much longer than the 

 others combined and, in Encyclops, the only 

 one of the three genera occurring in the 

 eastern United States, cylindrical. One 

 species, Encyclops cceruleus Say, green or 

 blue, shining, coarsely punctured, length 

 7-8 mm. should be looked for in southern
