Notes on a New England Aradid 
121 
Lugger, in the 6th. Rep. Div. Ent. Minnesota. St. Exp. Sta. 
1900 p. 40 described the egg of an Aradid, probably Aradus ro- 
bustus Uhl. as follows; ‘Rhe eggs glistening white in color are 
deposited under the bark.” 
Heidman, 1911 — Proc. Ent. Soc. Wash. XIII p. 134 de- 
scribed the egg of an Aradid, Neurocienus simplex as ;^‘Egg a- 
bout 1mm. long 5mm. wide; laid in a heap numbering from 20 to 
60 or more. Chorion whitish, irregular, coarse, hexagonal; no 
apical cap; the chorial processes seem to be wanting.” 
The egg of Aradus ^-lineatus Say is quite different in 
structure and the habit of oviposition is dissimilar. It differs 
in structure particularly in the flattened ventral surface and 
in possessing both a distinct cap and chorial processes, altho 
the latter are very minute and inconspicuous. The habit of 
oviposition differs in that all those which I have seen are de- 
posited singly as previously mentioned.
