F. SILVESTRI, EMBIIDAE. 395 
Remarks: This species, which I take much pleasure in 
naming after Mr. E. Jacobson, is closely allied to Oligotoma 
vosseleri, but sufficiently differing from it by the darker general 
colour, the stronger head with posteriorly less convergent 
sides, and the shorter processus of the left part of the 
abdominal tenth tergit (see fig. 5 and 6). 
Portici, April 1912.
