of use is simple aud readily seeu from the accompanying figures, which 

 represent the block from all sides. 



Tlie 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 I 

 above. 



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

 clean card-board cut sous to project somewhat on all sides may be used 

 for this iDurpose 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 collecting 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 — Erigeronramosus Walt. {strigo.sus 

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

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

 its eggs.
