Scudder's paper is based on the specimens obtained by all the 

 expeditions except the Beagle, Eugenie and Petrel, and he had 

 seen specimens of all the species enumerated by him, except 

 one, which is of uncertain occurrence. Butler referred two larval 

 mantids to the genus Vates and Scudder concludes that it was 

 impossible to have referred the specimens he knew to that genus. 



Twenty species of Orthoptera are given in this paper, these 

 species representing all the families except Phasmidee. All the 

 Blattids, however, five in number, are cosmopolitan species. Of 

 the remaining ffteen two are of such doubtful occurrence that 

 they may be excluded, leaving but thirteen indigenous species. 

 Moreover, since the forficulid, Anisolabis atmulipes Lucas, must 

 be regarded as an introduced species, this number must be still 

 further reduced to twelve. These twelve are included in eleven 

 genera, representing four families. The Blattidj£ and Forficu- 

 lidas are represented only by cosmopolitan species, and Phas- 

 midas is not known. Excluding the few doubtful cases, species 

 are referred to thirty-six localities, or excluding the cosmopol- 

 itan forms to twenty-eight. 



The above outline of our previous knowledge of Galapagos 

 Orthoptera has been given in order to clearly show the additions 

 made by the Hopkins Stanford Expedition. 



Messrs. Snodgrass and Heller spent about six months in the 

 Islands; usually staying only a few days at each one. Albemarle 

 was however twice visited and several weeks spent in its ex- 

 ploration. No special effort was made to collect Orthoptera as 

 the purpose of the expedition was to make as complete collec- 

 tions as possible of the entire fauna and flora of the islands. 

 The insect collecting was done chiefly by Mr. Snodgrass. 



The following table exhibits the distribution of the Orthoptera. 



It will be seen from this that Orthoptera were obtained from all 

 islands previously visited except two, Jarvis and Gardner, and 

 from four new localities, Narboro, Culpepper, Abingdon and 

 Bindloe. Omitting the cosmopolitan Blattids, which he made 

 no effort to collect, Mr. Snodgrass obtained all the species 

 hitherto known, except two, Closteridea batiri Scudd. and
