the manipulation of some of the artificially bred specimens. 
Prof. Poutton also exhibited a wall-like mass of egg-shells in 
which the arrangement to “break joint,’ as described by 
Mr. Lamborn, was clearly visible. This keen observer had 
written, Aug. 25th, 1911— 
“You will see, by egg-shells now sent, how wonderfully the 
eggs are disposed—in the form of a little wall, the eggs being 
in rows one above the other and each egg placed so as to 
cover the adjacent halves of two eggs below it. There is a 
fine opalescence too about the egg mass in a good light.” 
These specimens together with the remainder of those 
exhibited by Prof. Poutton were obtained by Mr. Lamborn 
at, or near, Oni Camp. 
THe SpHERICAL Bopirs ON THE CocooNs OF THE HypsID 
Mota DEILEMERA ANTINORII, OBERTH., ETC.—Prof. PouLton 
exhibited a large family of these moths—80 in number— 
together with their female parent, and 67 of the cocoons from 
which they had emerged. The exhibit had been recently 
received from Mr. W. A. Lamborn, who had bred the moths 
from eggs laid Aug. 13-18, 1911. Concerning the habits of 
the larva Mr. Lamborn had written, Sept. 19th— 
“In regard to the structures like Braconid cocoons I do 
not think there is much to add to what I have already written. 
The larva spins a few threads in the usual way. The hinder 
extremity of the body is gradually raised until it is brought 
to about an angle of 20° with the rest of the body, the larva 
meanwhile continuing to spin. When it has been in this 
position a few seconds the little mass is passed per anum, 
the larva ceasing work only during the actual passing of it. 
When several little masses have accumulated, the larva turns 
round, weaves silk over each and in turn drags each off by 
the silk and deposits it in the desired position.” 
In reply to further questions as to the details of the larval 
procedure Mr. Lamborn wrote, Nov. 12th— 
“In regard to the cocoons of Deilemera antinorvi the larva 
passes spheres per anum usually one at a time with an interval 
of perhaps half a minute between them. Sometimes two are 
passed, one following immediately on the other. When two 
or three spheres have accumulated at its ana] extremity the
