LONGICORNIA. 



DuEiNG my sojourn in the Transvaal I made every effort to 

 form a collection of tliese interesting beetles ; but they abound 

 more ill numbers tlian in species on the high and little-wooded 

 veld around Pretoria and Johannesburg, and are there princi- 

 ])ally floral members of the family Cerambycidse. I'he warmer 

 and better-wooded regions are more productive, as might be 

 expected, but in the Transvaal 1 always found the capture of 

 a Longicorn, beyond the usual predominant species, somewhat 

 uncommon in collecting experience. Many species come to 

 light, as does the fine Prosphilus sei-ricornis, which, as in 

 many other known species, emits a loud squeaking noise on 



* The poly]i and corbula of AgJaophenia Helkri have not befoi-e been 

 figured.
