H. thoracicus Melsh. H. parallelus Melsh. 
H. thoracicus was emerging from dead beech October 3, 1900. 
I have taken here a Hypophleus which is new, and for which 1 
propose the name Hypophlaus rugosus. I took the species years 
ago and gave specimens to Drs. Horn and Le Conte, who then 
pronounced it new. I have not heard that it has been described. 
Its characters are as follows: 
Hypophleus rugosus n. sp. 
Dark brown, subshining, linear. Thorax slightly longer than 
wide, squarely truncate in front and behind, sides arcuate, angles 
obtuse, coarsely punctured. Interstices forming longitudinal rug 
more evident in front and at sides. Elytra conjointly rounded at 
tip,obsoletely striate and densely punctate, punctures finer than 
those of thorax. Head evenly and finely puntured with a shallow 
constriction behind the eyes, which are very prominent. Antenne 
(including four-jointed club), ten-jointed. Length, 3.8 mm. 
Eight specimens. Cincinnati, Ohio.
