timber, and recommended that the wood should be sunk under water 
at the time when the perfect imsect made its appearance, by which 
means it was secured against further attacks.

PTINIDA. 
The name Bruchids is now given by several continental authors to 
this family, on the ground that the Bruchus of Geoffroy has the priority 
of the Ptinus of Linné; as, however, the name of Ptinide has been so 
long applied to the family, and the name of Bruchidz has been also so 
long used to denominate another well-known family, it seems a very 
great pity to cause the confusion that must necessarily result from the 
change of nomenclature. 
The family comprises about sixty genera and four hundred species ; 
some of the genera have, however, been subdivided into several further 
genera by different authors, especially Mulsant, Kiesenwetter, and 
Reitter; the species are widely distributed over the surface of the 
world, and are small, oblong, round or oval insects, which, in many 
cases, are exceedingly destructive ; they are characterized by having the 
antenne long and filiform, or very faintly serrate and inserted upon the 
front, as a rule, 11-jointed; the thorax is narrower than the elytra, and 
usually constricted at base; the elytra are, as a rule, more or less 
rounded, and sometimes globular, and completely cover the abdomen; 
the legs are long and not retractile, with the femora usually clavate at 
apex; the tarsi are 5-jointed, with the first joint not shorter than the 
second; the abdomen is composed of five ventral segments, of which the 
first is not elongate. 
The larve of the Ptinide do not call for any particular remark; they are small 
fleshy grubs, which have the body bent ina semicircular position, a character that 
causes them to bear a somewhat strong analogy to the larvae of the Lamellicornia ; 
there are no ocelli, and the antenns are short and inserted immediately above the
