black. Head black, closely punctate. Thorax longer 

 than wide, sides arcuate in front, sinuate posteriorly, disc 

 slightly depressed each side, surface moderately coarsely 

 not densely punctate and alutaceous. Elytra moderately 

 coarsely and closely punctate, finely pubescent, faintly 

 subcostulate. Body beneath finely punctulate. Legs 

 black. Length .20-. 28 inch.; 5-7 mm. 



In some specimens an indistinct piceous spot occurs 

 in the thorax, others again have pale tibiae. 



Occurs from the middle States to Florida and Texas. 



Copidita suturalis n. sp. 



Form slightly robust. Antennae piceous. Head yellow, 

 coarsely punctate. Thorax scarcely longer than wide, 

 sides arcuate in front, sinuately narrowing posteriorly, 

 disc coarsely and closely punctate, color variable, nor- 

 mally yellow at middle, broadly piceous each side. Elytra 

 moderately densely and coarsely punctate, distinctly sub- 

 costulate, color piceous, with the suture and side margin 

 pale to a variable degree. Body beneath either entirely 

 piceous or with the middle pale and sides piceous. Legs 

 pale, tarsi and knees darker. Length .26-. 40 inch.; 

 6.5—10 mm. 



This insect resembles closely specimens which have 

 been received from Europe, as Dryofls vittata Fab., but in 

 the present species the surface is more coarsely punctate 

 and the mandibles are bifid. Some specimens so closely 

 resemble Oxacis vittata that it is necessary to examine the 

 mandibles to separate them. No sexual differences have 

 been observed. 



Occurs abundantly in Georgia and Florida, and speci- 

 mens have been taken in southern New Jersey by Mr. 

 Wenzel.
