BOLITOPHAGTTS, Illiger. 

 Bolitophagus, [lliger, Die Ksefer Preuss,, p, 100. 

 Eyes entirely divided, sides of head prominent. Antenna 1 eleven-jointed. 



P>. oorticola, Say, Jouni. Acad. V, 288. 



The margin of thorax is strongly crenulate and deeply notched in front of the hind 

 angles. The surface is covered with numerous tubercles and the elytra ornamented with 

 widely interrupted elevated ridges. 



Length .33 inch. 



Occurs in the Middle and Eastern States. 



I!. depressus, Randall, (Eledona) Bost. Joura. II, 31; tetraopes, Newman, (Bold.) But. Mag. V, 378. 



Differs from the preceding, in having the thorax simply coarsely punctured, with the 

 sides regularly rounded and margin scarcely crenulate. The elytra arc finely costate, the 

 interstices having a single row of coarse punctures. 



Length .20-.30 inch. 



Middle an I Eastern States and Canada. 



ELEDONA, Lair. 

 Eledona, Lata'., Precis d. car. gen. d. Ins., p. 19. 



Differs from the preceding genera, in not having the sides of the head prominent in 



front of the eyes. The eyes are about half divided. Front rounded, not prominent at 

 middle. Antennae clavate and compressed. Thorax distinctly margined, margin finely 

 crenulate. 



E. fungioola, brown, opaque, oval, sub-cylindrical. Head densely and coarsely punctured. Thorax broader 

 than long, very rugosely punctured, convex, anteriorly feebly emarginate, base bislnuate, sides feebly rounded, grad- 

 ually wider behind. Elytra convex, broadly rounded at apex, base feebly emarginate, surface linoly eostulate, inter- 

 si ices vvi1.li a single row of coarse punctures. Beneath dark brown, coarsely punctured, antennse and legs paler. 



Length .14 inch. 



Middle States. Closely resembling E. agaricicola of Europe. 



This insect has been associated in collections with the next as its female, the differ- 

 ences appear to me to warrant its separation as a species of this genus. The characters 

 are all those of Eledona. 



RHIPIDANDRUS, Lee. 



Rhipidandrus, Lee,, Class. Col. N. A., 380. 



Rhipidandrus differs from Eledona in having the eyes larger, more convex, more 

 coarsely granulated, and not emarginate by the sides of the front. The front is narrow, 

 epistoma rather prominent, and truncate at middle. The antennse are pectinate from the 

 fifth to last joints, the fifth joint with a shorter branch than those which follow. The 

 thorax is without flattened and crenulate margin.
