ENTOMOLOGICAL RESULTS (5) : 



THYSANURA AND TERMITID^. 



By Nathan Banks, 

 U. S. National Museum. 



Two species of Thysanura were collected on the Galapagos 

 Islands, and one, in considerable numbers, on Clipperton Island. 

 All appear to be new, but belong to genera of world-wide dis- 

 tribution. One of the species from the Galapagos Islands is of 

 very large size. The species from Clipperton Island is inter- 

 esting on account of lacking a curious character present in 

 many, if not all, of the other species of the genus. The Col- 

 lembola do not appear to have been collected, although doubt- 

 less fairly abundant on the islands.
