Notes on Embia (Rhagadochir) apicata Silvestri, sp. n. 
(p. 449), and a larval Embia on Cotton-seed Sacks. 
Material :—Two g,2 2 from webs on the Para Rubber 
trees at Agege; the 3 ¢ bred at Moor Plantation and referred 
to as sent off in a letter of March 23, 1918, the 2 9 sent 
from Agege, Oct. 1917. Webs of the same species from 
Agege, sent Feb. 8, 1918. Also 4 larval Embiids from 
webs on cotton-seed sacks at Moor Plantation and web- 
covered sacking from the same store, referred to in a 
letter of Aug. 12, 1918. Farquharson considered that 
these latter were distinct from the Agege species, but 
Prof. Silvestri thinks that they are probably the same 
(p. 450). ] 
Government Farm, Agege. 
Dec, 15, 1916.—There are one or two species of Embiids 
about here. They are extraordinary. Their “ reversible ” 
gear must be most efficient, for they can run backwards or 
forwards equally easily and rapidly, 
Agege. 
Oct. 18, 1917.—I thought at the same time [as the 
observations on the moth larvae, p. 410] it might be worth 
while to note any other insects that share the Para Rubber 
trees with Oecophylla. One variety I have long noticed 
and always intended to send. I hope to send some soon. 
These are Embiids. There are several trees here that 
are covered round and round their stems up to the forks 
(about 10 to 12 feet) with a glistening felt of silk, which 
gives them in a half light a curiously ghostly appearance. 
On closer inspection the web is seen to cover an extra- 
ordinary network of “tunnels” of much denser opaque 
fabric, but the insects do not confine their journeyings to 
these thicker-walled tunnels, but can easily be seen under 
the general covering web. I once saw a winged one, but 
lost it, and have never seen another; but I recollect still 
that the wings were of a blue-black colour and somewhat 
lustrous like those of some wasps. I am in hopes that 
I may get winged forms again, for the species, whatever 
it is, is quite common on the Rubber trees—Oecophylla
