ton, and Leptostylus bore in the smaller branches of Ftcus, but were much 
more common in the Biscayne Bay country. 
The Poison Wood (Rkus metopiuin) is greatly subject to the attacks of 
Tetrapriocera longicornis, but the tree vigorouslj' defends itself by exud- 
ing from the wounded places quantities of a resinous gum which drowns 
the boring beetles. Trees weakened by fire or other causes are usually 
riddled with the holes of the Tetrapriocera which seems to attack the tree 
for feeding purposes only and not for oviposition. At least I never found 
the larva in the Poison Wood, though I discovered it later at Biscayne Bay 
under quite different conditions. An undescribed species of Te.retriosoma 
preys upon the Tetrapriocera and may frequently be found by cutting into 
the burrows of the latter. The tree further harbors a peculiar Scolytid (a 
new Pityophthorus}, which constructs very neat galleries under the bark, 
and several other interesting species, e. g., Scalidia linearis and Dysme- 
rus basalts. 
The Cocoa-plum (Chrysubalanus icaco] is also among the more common 
trees and appears to be the only food-plant of Pseudomns inflatus, a remark- 
able new Xyleborus allied to pyrt, and a large species of Caryoborus. The 
genera Lembodes and Erodiscus are also not rare on this tree, but do not 
seem to be confined thereto. 
Mr. Schwarz added a short account of the insects annoying and 
molesting man on Key West. There is no want of the various 
in-door pests, such as ants, roaches, fleas and bed-bugs. Out-doors, 
mosquitoes, Chrysops, Tabanus, Ceratopogon are not unusually 
troublesome, while ticks and red-bugs (Leptus irritans) appear 
to be entirely absent. The most interesting species is the jigger 
{Rhynchoprion penetrans}, which is quite abundant in the out- 
skirts of the city, and which is said to occur also at Lake Worth, 
some 250 miles farther north. 
Mr. Schwarz also exhibited larva and imago of Oligotoma Hub- 
bardi (family jEmbidcz}. The larva is not uncommonly met 
with in southern Florida, occurring singly in the old galleries of 
wood-boring insects. It is quite active, and no spinning habits 
were observed. Only a few imagos, apparently all males, were 
observed occurring in company with the larvse. The species was 
never seen on the wing.
