Prof. Smith displayed some Scolytids, including specimens of 

 Dendrodonus n. sp. , T. Calligraphus and cacographus, Gnatho- 

 trichus materarius and Crypturgus ahitaccus, taken in or under 

 pine bark at L,ahaway, N. J., on November 21, 1900, also por- 

 tions of the burrowed bark showing that it was possible to

 stages would generally be found. Gnathotrichus uiatcrariiis 

 did not tunnel in the bark, but made deep and intricate galle-

Mr. Franck exhibited a fine series of Callimonpha Iccotitci 

 and confusa showing gradations which seemed to prove beyond

 positions upon their respective food plants. Discussion appro-
