those in tlie middle row much larger than the others, taper slightly poster-

 angles are jjroduced into a two-pronged projection, the inner prongs of 

 which are bent inward, nearly meeting ; head dark brown ; a prop-leg 

 beneath the last segment ; length nearly one inch. I found several of 

 these in some decayed oak-wood April 5, and the beetles Avhich issued 

 from them were first observed July 8. One of these larvse devoured a
