This species, altho plainly a Symphyothrips, has some structures 
which suggest other genera. The reticulated surface of the 
head and prothorax would suggest Glyptothrips, the strongly 
thickened fore femora Nesothrips and the tibial tooth Klado- 
thripinae. 
Described from a single female taken from the skin of a tan- 
gerine from Buenos Ayres at New York by Emile Kostal of the 
Federal Horticultural Board, July 2, 1924. 
NETTLING CATERPILLARS 
Three caterpillars which are provided with nettling hairs are 
common in Florida. They are the Saddle-back (Sibere stimylea 
Clemens), the larva of the Hag Moth (Phobetron pitheciumS & 
A), and the larva of the Puss Moth (Megalopyge opercularis 
S & A). The result of coming into contact with the nettling 
hairs of these caterpillars varies greatly with different individ- 
uals. An instance of very severe pain caused by the Puss Moth 
larva has recently been reported by Mr. E. W. Pettersen, a drug-
