' When, in 1921, I published the description and figure of a new genus and 
species of the Hemipterous family Myodochidae from Juan Fernandez, brought 
home by Prof. SKOTTSBERG’s expedition, I had only seen the pinned insects 
of the expedition, and was unaware of the fact that material preserved in 
alcohol had also been collected by Mr. BACKSTROM, the zoologist of the ex- 
pedition. Having now received from the Riksmuseum of Stockholm all the 
Hemiptera collected on Juan Fernandez and Easter Island, I give below an 
account of them. 
The total lack of representatives of the family Miridae is surprising, but 
as these islands have a rich vegetation, species of this family will doubtless 
be found in the future. 
A small Delphacid kindly was examined and described by Dr. F. Muir, 
of Honolulu, who has made this difficult group his special study for several 
years. 
As to the general nature of the islands I refer to Prof. SKOTTSBERG’s 
highly interesting and profusely illustrated popular account of his expedition.’
