993 (9110). XYLEBOBUS XYLOGRAPHUS Say, 1825, 256; ibid. II, 318. 



"Cylindrical, ferruginous, shining, thinly pilose; thorax oblong, deeply 

 punctate behind; elytra deeply punctate-striate, intervals slightly convex, 

 uniseriately faintly punctulate; apex convex, declivity rounded, punctate- 

 striate, shining, suture and third interspace each with single tubercle, 

 second unarmed. Length 2.5 mm." (Eichhoff.) As pointed out by Hop- 

 kins, this description errs in giving the third interspace as tuberculate, 

 the first only being actually so. In separating howardi and fitchi, 

 "closely allied to xyloffraphus," he defines it by "elytral striae impressed 

 but not on lateral area, pronotum with round dorsal elevation, posterior 

 dorsal area distinctly punctured, elytral punctures moderately coarse, de- 

 clivity convex, shining, sublateral margin obtuse. Length 2.5 2.7 mm.
