MonoGrRAPH OF THE Bompycinre Morus or NortH AMERICA, BY 
A. 8. Packarp: Part IIT.—Regarding the review of this work (antea, 
pp. 69-71) I may perhaps say that the whole of the plates from Plate 
LXXXIV to CXIII are from photographs taken by myself, the 
“J. H. Watson” on the text facing the plate indicating the same. 
All the specimens without exception are in my collection, those from 
other collections, such as Lord Rothschild, Mr. Chas. Oberthiir, etc., 
included. For the benefit of students of the Saturnid, at Prof. 
Cockerell’s request the identity of each specimen is fixed with a blue 
ticket on the pin.—J. Henry Watson; 70, Ashford Road, Witbing-
