In the Entomological Magazine for 1836, Haliday published a Monograph 

 of the Sphceroceridce or Borboridce, and in the Annals and Magazine of 

 Natural History for 1839 one of the Hydromyzidce or Ephydridm, describing 

 with his usual conciseness and accuracy many new species. A large number 

 of the specimens from which these descriptions were made still exist in 

 Haliday's Collection in the National Museum of Ireland, Kildare Street, 

 Dublin ; and though unfortunately in many cases (nearly all the Borboridce) 

 the original labels are missing, still the fact that these specimens are 

 undoubtedly the identical ones studied by Haliday, while the periodicals in 

 which the descriptions appeared are not easily accessible, may make the 

 publication of the following notes of some value to students. 



Borboridse. 



The species are numbered as in Haliday's Monographs. 



SpHjEROCERA. 



1. Splueroeera subsultans F. — Several specimens of this very common 

 species.
