176 THE ENTOMOLOGIST. 



three species appear to occur on nearly all the coasts of 

 N. Europe, but to be generally confounded together. Thom- 

 son clearly has not found obscurella, Grav., at all ; and his 

 obscurella corresponds with grisea, Kraatz^ for Kraatz says 

 that it was sent him by Thomson as obscurella, Gyll. The 

 grisea of Tliomson is, however, evidently not that of Kraatz, 

 but the opaque species recently described by Fauvel. In 

 this country we have identified the opaque large species 

 wrongly with grisea, Kraatz; it should be Algarum, Fauv., 

 as an examination of Kraatz's description will soon show ; 

 moreover, Kraatz had a faint inkling of the existence of 

 Algarum, Fauv., as is shown by his final observations on A. 

 obscurella. In this confusion it seems to me impossible to 

 restore Stephens' name to any of the species, as he certainly 

 never characterized them. Mr. Rye, in his Catalogue, has 

 proposed the name Fauvelii for Algarum, Fauv., but this 

 alteration is unnecessary. 



Oxypoda umbrata, Er. nee Gyll. — I was unaware till lately 

 that Kraatz had re-named Erichson's species O. humidula in 

 Berl. Ent. Zeit. 414 (1865). The name Erichsoni, here pro- 

 posed, is therefore withdrawn. 



O. sericea, Heer. — Comparison of typical specimens sliow 

 that Waterhouse's nigrina belongs to this species. Fauvel 

 also unites O. exigua, Er., but in this I cannot concur. 



O. incrassata, yl/«//.9. — Mr. Waterhouse, at the time, ex- 

 pressed doubts as to whether this species was not identical 

 with his aterrima, which now proves to be the case. 



IJomalota Algae, Hardy. — Hardy's name certainly ought 

 to lie retained for one of the species which he described, and, 

 as both flavipes and maritima are preoccupied, it may be ad- 

 vantageously employed. When two species are confounded 

 under one name, it is usual for the person who distingui-shes 

 them to aj)ply the old name to one or other of the separated 

 species. 



H. depressa, Fahr. — The use of this name will obviate the 

 confusion attached to H. brunnea, Fahr., which is identical 

 with IJomalium brunneum, Pk. 



Oligota ])arva, Kr. — Kraatz has made this correction, the 

 name pygma^a being preoccupied. 



Quedius semiobscurus, Er. — Thanks to erroneous types, 

 Ericlisun and the succeeding authors were entirely uiisled as
