and all the males to L. staphylinoid.es. As pointed out by Piaget, he figured the 

 latter without a pale furrow along the middle of the abdomen, but this I consider 

 of little consequence ; I have a specimen of this description. Both of Denny's 

 names are prior to Piaget's, and seeing bassance comes first in Denny's work, the 

 correct name of the species, if the views expressed above are right, would appear 

 to be Lipeurus bassance (D.). 



L. squalidus, N. — From Pintail (Dafila acut'i) off Bo'ness, Oct. 1884; Mallard, 

 Gosford Bay, Nov. 1884 [and Edzell, Jan. 1907]; Teal (Nettion crecca), Culross,

 that T cannot hesitate to record it as such.
