NOTES ON THREE LITTLE-KNOWN SPECIES of BRITISH HEMEROBID^. 

 BY E. m'LACHLAK, F.L.S. 



Having been engaged in an examination of the British species of 

 Hemerohidce and allied families, preparatory to a Monograph of the 

 species which T intend to work out in the same manner as that followed 

 in the Trichoptera, I have been for some time aware of the existence 

 in this country of three species omitted in Dr. Hagen's synopsis of the 

 British species, published in the Entomologist's Annual for 1858 ; and I 

 have thought it advisable to lay before those readers of this Magazine 

 who attend to this subject, a short account of these three species, all of 

 which we owe to the indefatigable researches of Mr. J. C. Dale.

 the testaceous thit of the anterior wings, and by the presence in these
