I received the name of this insect from Mr. Pascoe, years ago, 

 but I cannot find that he ever described it. 



I have now, I think, recapitulated all the known species of 

 Pterohelceus with the exception of P. planus of Blissington-^- of 

 which species I have never seen a description. I have also added 

 largely to the number of new species, but I believe there are 

 many yet remaining to be described. 



The remaining genera of the Helseides, Helcms, SymiJetes and 

 Saragus will form the subject of another Paper.
