Mr. C. A. Frost has stated that it is remarkable that so 
many of the species listed below are “scavengers or inclined that 
wav.” He adds that he believes it very likely that (of the earlier 
forms) Altagenus, which was abundant, Laricobius, a rare form, 
possibly Cryptophagus, and Glischrochilus, regularly hiber- 
nate in white pine shoots. The occurrence of Ptinus fur, how- 
ever, he considers unusual and yet it occurred in significant num- 
bers. The striking abundance of Galerucello . luteola, the elm leaf 
beetle, seems worthy of note.
