This species was origiiially described by Stal from the Galapagos (without 

 further specification) and from the island of Puna in the Gulf of Guayacpiil. 

 It will probably therefore be found upon the continent, but Saussure was un- 

 ac(|uainled with it when he prepared his Prodroraus. Stal remarks : "Sjiccimen 

 Punense in omnilnis obscurius." The pallid tarsi in strong contrast to the 

 apically infuscated tibiiE are not specified in his description. 



Five specimens before me from Charles Island have the basal and middle 

 dark bands of the tegmina more sharply defined and less inclined to be mottled 

 than those, si.\ in number, from Chatham Island, and have a less nundier of 

 fuscous points in the apical third of the tegmina ; otherwise, I can see no 

 difierenccs between them. A single specimen from Gardner Island is like the 

 Chatham Island specimeiis, which is the opposite of what would be looked for, 

 Gardner Island being a mere satellite of Charles and distant from Chatham. 

 Bruner ci-edits the two specimens he saw to James I.sland, but the labels 

 attached to them are marked Chatham Island. The specimen from Gardner 

 Island and three of the Charles Island specimens are of Dr. Baur's collecting. 

 The remainder are from specimens collected by the naturalists of the "Alba- 

 tross," on different occasions in ISSS and 1891.
