NEW BRITISH SPECIES, ETC., IN 1866. 59 



be distinct from tliat species. The elytra seem to be darker 

 than in the other species. 



8. Phytosus balticus, Kraatz,' Berlin. Ent. Zeit. 1859, 52 ; 



Wollaston, Col. Atl. 455, 1249; Rye, Cat. "British 

 Beetles "; G. R. Crotch, Cat. Brit. Col. ed. 2. 



This is the insect, taken in the north of England (especially 

 by Messrs. Bold and M. Young), usually known to us as 

 nigriven tris, C h e v r . 



The latter species also is included in Mr. Crotch's Cat. ; 

 and, as I am informed, comes from the South Coast. I have, 

 however, balticus from the Isle of Wight. 



The true P. riigriventrls seems to be a little larger and 

 broader than P. balticus, with the elytra less parallel, and 

 the limbs somewhat longer; it is exceedingly pale rufo- 

 testaceous, with the fifth segment (and the whole or part of 

 the fourth and sixth segments) of the abdomen black. 



9. Aleochara grisea, Kr., Ins. Deutschl. ii, 96 (note) ; 



G. R. Crotch, Cat. Brit. Col. ed. 2. 

 Fauvelii, Rye, Cat. " British Beetles." 



This insect, taken not uncommonly on the Scotch coasts, 

 also by me at Broadstairs, and by Mr. Waterhouse at South- 

 end, has long been in our collections as a new species, through 

 the erroneous impression that Kraatz's grisea was a synonym 

 of Kir bit, Steph. 



It is readily distinguished from the latter by its more dis- 

 tinct punctuation (especially visible on the head) ; and from 

 A. ohscurella, Grav., by its much longer and darker antennae, 

 and more evident punctuation. 



Mr. Crotch deposes Zir&i?* as a synonym of the subsequent 

 algai'uyn (L presume, of Fauvel).
