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.*
