frogs, but never of toads. He had, however, observed them, and 
they are, in his opinion, decidedly more beneficial than other- 
wise. Mr. Schwarz said toads eat May-beetles, one toad exam- 
ined having no less than eight Lachnosternas in its stomach. In 
the wilder parts of the Lake Superior region the best method of 
finding rare species is in the stomachs of toads. He had reason 
to believe that some of the harder weevils pass through the toads 
without being in any way injured thereby. 
Mr. Schwarz then read the following note : 
ON A COLLECTION OF COLEOPTERA FROM ST. AUGUSTINE, FLORIDA. 
BY E. A. SCHWARZ. 
Through the kindness of Dr. John Hamilton, of Pittsburg, Pa., I re- 
ceived lately a list of nearly six hundred species of Coleoptera, collected 
by the Rev. Charles Johnston in the vicinity of St. Augustine, Fla. The 
species have been named -by Dr. Hamilton, and since he is known as a 
careful and experienced Coleopterist the determinations are no doubt re- 
liable. 
As I never collected in northern Florida, and since our knowledge of 
the Coleoptera of that part of the State is still very defective, the list js an 
important contribution to the knowledge of the fauna of Florida, and this 
the more so because an exact locality is given, whereas, in most other 
species coming from other sources, but presumably collected in northern 
Florida, no precise locality is given, the species being simply labeled or 
recorded from " Florida." Moreover, this list comprises such a large num- 
ber of species being defective only in the smaller and less conspicuous 
forms that the character of the fauna of that locality may be fairly recog- 
nized therefrom. Finally, the collection is of special interest to me be- 
cause it comes from a part of the coast not so verv far remote from the 
line which, at a former occasion, I have designated as the northern limit 
of the semi-tropical fauna, and this collection is, therefore, able to prove 
ordisp rove the correctness of my statement. In scanning the list I find 
only five species which belong to the West Indian colony in Florida, viz., 
Leptostylus terrcecolor, Ischnocerus infuscatus, Artipus ftoridanus, Pach- 
nceus opalus, Phodobcenus pustulosus. The first named two belong to those 
species of the West Indian colony which have already acquired the power 
of changing their food-habits and to extend their geographical range 
northward. They are now quite common anywhere in the peninsula of 
Florida. The third species, Artipus floridanus, is unquestionably also an 
immigrant from the West Indies, but does not seem to have been pre- 
viously described from that locality. It is by far the commonest beetle in 
semi-tropical Florida, and, economically, of great importance. Its injury 
to lime trees has already been referred to by Mr. William H. Ashmead in 
his work on Orange Insects, but I found its destructive powers much more
