1'. poroata, Lee., loe. oit. (Nosoderma) Lee., Proo. Acad. 0—235. 



Occurs abundantly in Oregon. 

 Length .55-.G2 inch. 



P. oboordata, Leo., Class. Coll. N. Am. 816; (Boletophagus) Kirby, N. Z. 886. Eastern and Middle States 

 and Canada. 



These two species are closely allied and not easy to describe as distinct. Porcata is, 

 however, dark brown, while dbcordata is ferruginous brown. Both species may be described 

 as having the following elytral sculpture: 1st. A sutural elevated ridge. 2d. A ridge ex- 

 tending from the base of elytra more or less continuous, terminating in a tubercle. 3d. A 

 short ridge. These are separated from each other by a row of deep perforations. In por- 

 cata the second ridge is continuous and the third not very prominent ; in oboordata,, the 

 second ridge is interrupted at its lower half, and consequently not reaching the tubercle, 

 and the third very prominent. Similar in length to the preceding.
