Additions and Corrections. 
The MSS. of this volume were sent for publication before I had heen able to 
consult the ‘Zoological Record” for 1906, which did not reach Hawaii till well on 
in 1908; consequently, to bring them up to date, I have had to add several forms 
described and notes made in 1908 and 1909, as well as some in 1906 and 1907; 
these four years have been especially productive in papers and books dealing with 
Cimicidae, in particular from the pens of Bergroth, Breddin, Distant, Horvath and 
Schouteden. I have also added many earlier references to food-plants, (or as it is 
safer to term them — “host-plants”), which I have unearthed from papers previously 
maccessible to me, as well as some other references that I had decided to omit when 
compiling the MSS. In this.connection, I have to thank Mr. Dames for his care in 
tracing up separata for me* many rare contributions, and also the United States 
Bureau of Agriculture, through Dr. Howard, for the loan of some rare works which 
I do not possess. 
This volume is now brought up to date with the “Zoological Record’ for 
1907 (the latest that has arrived in Honolulu at date of writing, Noy. 8r4 1909); 
I have of course added all the new genera and species known to me as having been 
described during 1908 and 1909. 4 
While writing this, I have received Schouteden’s Catalogue of the Hemiptera 
of the Belgian Kongo, (Ann. Mus. Congo, Hém. sér. 2), which has such an 
unwieldy referential title, that I allude to it here as “Cat.’. I have included the 
new forms, but fresh localities, descriptions and figures must be sought for in the 
work itself. The same remarks apply to Distant’s “Rhynchota vol. IV”, in the 
“Fauna of India” series. 
After proofs had been passed of almost all this work, I received Bergroth’s 
supplement to the first volume of “Lethierry and Severin’s Catalogue des Hémiptéres”’, 
in the Mém. Soc. Ent. Belg. XV. 131—200 (1908). The changes in location of many 
genera and species are noted here, but the so-called “emendations” of names have 
been ignored, and nust be looked for in the paper itself. 
For convenience, these “Addenda and Errata” are divided into several sections: 
(a) Further notes on Classification. 
(b) Printer’s and other minor errors. 
(c) Additional genera and subgenera. 
(d) Additional species and varieties. 
(e) Additional systematic notes. 
(f) Additional biologic references. 
(g) Additional host-plants. 
(h) Additional localities. 
At the close, will be found a list of the new genera and species, or new 
names, proposed in this volume, followed by general and generic Indexes. The 
specific Index will be issued with vol. II, to avoid delay. 
(a) Further notes on Classification. 
Owing to my not having seen specimens of any Phloeine at the time that I 
prepared the table of subfamilies, I made a serious mistake therein, and take this 
opportunity to offer a fresh table which I think expresses more correctly their
