I am much indebted to Mr. Rowland E. Turner for pointing out 

 this synonymy. The only excuse for it is the erroneous treatment 

 of Tiphia ephippium Fabricius given in Dalla Torre's catalogue.

Allied to contigiius (Cresson) but readily distmguished by the dense

UIODONTUS CORUSANIGEENS, new species. 



In Fox's key ^ to the North American species of Psen tliis species 

 runs in with cylindricus and mixtus but the smooth scutum, carinae on 

 the face and venation will readily distinguish it from both of these.
