of use is simple and readily seen from the accompanying figures, which 

 represent the block from all sides. 



The advantages of this system are the ease and security with which 

 the block can be placed into or removed from a box; the ease with which 

 a vial can be slipped into or removed from the wire clamps; the security 

 with which it is held, and the fact that practically no part of the con- 

 tents of the vial is obscured by the holder— the whole being visible from 

 above. 



The beveled ends of the block may be used for labeling, or pieces of 

 clean card-board cut so as to project somewhat ou all sides may be used 

 for this purpose and will be held secure by the pins between the block 

 and the cork of the drawers.

NOTES ON LANGURIA. 



By F. H. Chittenden. 

 While on a colleetiug trip during June of last year I observed a speci- 

 men of that handsome little Erotylid beetle, Languria mozardi Latr. on a 

 Composite plant, the daisy flea-bane— Erigeron ramosus Walt, (strigosus 

 Muhl.)— the^stem of which it was engaged in gnawing, having already 

 cut with its maudibles a fair-sized hole preparatory to the deposition of 

 its eggs.
