ADDENDA AND CORRIGENDA. 
p. 2, line 6 and 7 from top, should read: “Shatiloff’s portrait 
is in Vol. I” etc. 
p. 60, line 15 from bottom. Mr. G. H. Verrall wrote me that 
“Curtis’s Guide, Edit. II, p. 280, has Malacomyza ”, 
and not Malacomyia, as I had quoted it on my p. 60. I 
find now that in the copy of Curtis’s “Guide”, annotated 
by Haliday, which he had sent to Loew, and which is 
now in my possession, the original spelling Malacomyza is, 
by Haliday himself, converted into Malacomyia , by the 
erasure of the 2 , which is replaced by an i. I had not 
noticed this change before, and was, therefore, puzzled 
by the spelling Malacomyza in another passage (compare 
the same page 60, six lines below), 
p. 61, line 8 from top, read 1867, for 1847. 
p. 142, line 6 from bottom, read 1855 for 1885. 
p. 144, at top. Mr. G. H. Verrall called my attention to the tact 
that, “as Zetterstedt missed pages 5100 to 5999 in his 
work, there were only 5709 pages, which make an aver¬ 
age of 408 per volume”. A corresponding change must, 
therefore, be made in my letter-press. I find now that 
Zetterstedt himself has called attention to this omission. 
At the very end of his work, Vol. XIV, p. 6609, I find the 
passage: “ Observandum: In Tomo XIII, paginis 6000, 6001, 
et sic porro; lege: 5000, 5001 et sic porro”. But here 
Zetterstedt commits a new mistake; it should be: 5100, 
5101 etc. up to 5999. 
p. 145, line 9 from bottom, read 1845 for 1885.
