2344 (7532). Hypophlceus parallelus Mels., Proc. Phil. Acad Nat Sci 



III, 1846, 03. 



Elongate, subcylindrical, parallel. Uniform reddish-brown, shining. Tho- 

 rax as long as wide, front angles prominent, acute, hind ones rounded ■ sur- 

 face finely, rather closely punctate. Elytra not striate, the punctures fine 

 and ra.ther dense. Length 3.5-4 mm. 



Lake County; scarce. July 23. Occurs beneath bark. Ranges 

 from Canada to Arizona. 



2345 (7535). Hypophlceus thoracicus Melsh., Proc Phil. Acad Nat Sci 



III, 1846, 63.. 



Elongate, subcylindrical, convex. Reddish-brown; elytra black, sparselv 

 pubescent with erect yellowish hairs. Thorax slightly longer than wide 

 sides almost straight, angles all rounded; surface finely and sparsely punc- 

 tate. Elytra little more than twice as long as thorax ; sparsely and finely

H. cavus Lec. was described from Kentucky and H. rugosus 

 Dury from Cincinnati. Both probably occur in the southern third 

 of the State. 



Tribe VI. BOLETOPHAGINI. 



. 0bl(m g< opaque, winged species having the surface roughened 

 with tubercles ; head received in thorax as far as eyes, which are 

 coarsely granulated, deeply emarginate and with a large groove 

 beneath them for the reception of the base of the antennae; epi- 

 pleurae narrow; front coxa- transverse middle ones with a small but 

 distinct trochantin; hind coxae well separated, the intercoxal process 

 triangular; tarsi pubescent beneath, the last joint longer than the 

 others united. Two genera are known, both being represented in 

 the State. The species occur on woody fungi which grow on the 

 sides of trees or stumps or benea th bark.
