* For the sake of uniformity the subgenera of Ilaliday and Stcnhammar are 

 treated here as genera. 



f Stenhammar's application of the generic name Psilopa, thougli not to the 

 original type, is adopted, to get rid of the synonym Hygrella, condemned on etymo- 

 logical grounds by Agassiz, not without reason. Tlic diircrent accent will admit 

 Psilopa to stand along with Psilopus (Fam. Dolichopidcv, i. 150).
