[Eead December 5, 1878.] 



The insects described in the present paper were collected by 

 Mr. Charles Darwin, and have been in my father's collection for 

 many years undetermined. 



The first that I have to notice is an example of Brachelytra 

 belonging to the genus Phi/tosus, and from the Falkland Islands. 

 The species of this genus have hitherto only been recorded from 

 Europe, Morocco, the Canary Islands, California, and Kerguelen 

 Island. It should be noticed of that here described that it has 

 unusually long and slender claws ; this peculiarity is noticed by 

 my brother in the species described by him from Kerguelen 

 Island, but this is a small species. 



The second species here referred to is also from the Falkland 

 Islands : it belong's to the genus Choleva. The species of this genus 

 are widely distributed, and have been recorded from Europe, N. 

 Africa, Madeira, Tasmania, N. America, Venezuela, and Chili. 

 That now denoted is a very remarkable one, on account of its 

 elliptical form and strong punctuation. 



The third insect I have to record is a species of the genus 

 Elmis from St. Helena, of which Mr. Darwin found two speci- 

 mens. This genus was not known to occur in this locality when 

 the late Mr. "Wollaston published his work on the Coleoptera of 

 the island ; it is therefore an interesting addition to the fauna. 



The next species also comes from the same locality ; it belongs 

 to the widely-distributed genus Antliicus. This genus, however, 

 has not as yet been recorded from there. Mr. Darwin also ob- 

 tained the following species from St. Helena, recently described 

 by the late Mr. "Wollaston : — Oxytelus alutaceifronsj CryptopJiagus 

 gracilipes, Notioxenus ferrugineus, and Homododera 'pygmcea. 



I have also called attention to a very interesting species of 

 ScapTiisoma from Rio de Janeiro, remarkable for its elongate com- 

 pressed form and from being the first species of this genus that 

 has been recorded from South America. 



It remains now for me to mention a new genus of Philhydridae 

 from the Cape of Good Hope, allied to HelopJiorus. The special
