688 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



of an insect was heard in one of the leaves of this table, which noise continued for a 

 year or two, when a large long-horned, beetle made its exit therefrom. Subsequently 

 the same noise was heard again, and another insect, and afterwards a third, all of 

 the same kind, issued from this table-leaf, the first one coming out twenty and the

 which we have any record, and it is desirable to ascertain, if possible, what insect 

 this was. John J, Putnam, esq., of White Creek, N. Y. , was a young man residing 

 at his father's when these remarkable incidents occurred. On showing to him speci- 

 mens of all the larger long-horned beetles of this vicinity, he poinf/S to Cerasphorus 

 balteatus as being the same insect, according to the best of his recollection, but is 

 not certain but it might have been the Callidiuin agreste. 



" This testimony, in connection with what President Fitch, of Will- 

 iams College, says of the insect in the notice above referred to — ' its 

 color dark glistening brown, with tints of yellow ' — releases us from all 

 doubts upon this subject, as the agreste is of a uniform brown, whilst 

 the balteatus commonly presents traces, more or less distinct, of an 

 oblique yellowish spot or band near the middle of the wing-covers."
