108 THE REV. F. W. HOPE’S CHARACTERS AND DESCRIPTIONS OF 
family will admit of yet more subdivisions. Stenocorus discoideus, Sturm, for instance, 
with Sten. rufipes, Klug, both from Mexico, must at some future time be formed into 
a subgenus. 
Of the new genera and species indicated in the preceding table, I propose at present 
to illustrate but two. The illustration of the others would amply repay any one for the 
time and patience which he might devote to their attentive investigation ; and I should 
be happy to aid him in such an undertaking. All the insects referred to are con- 
tained in my collection, on which the table is, in fact, entirely founded.
