$ Rufotestaceous ; head, metathorax, and posterior portion of the 

 abdomen infuscated. Antennae fuscous, yellowish at the base, 14- 

 jointed. Legs ferruginous, 4 posterior coxae slightly infuscated, as 

 well as the middle of the femora and tibiae. Abdomen fuscous, pale 

 at the base ; 1st segment yellow or ferruginous, slender, linear. 

 Valves of the terebra obtuse, black. Haliday has made a section of this 

 species, at the same time remarking that except in being apterous, 

 it differs in no respect from its congeners. Length, |-1| lines. 



Rare ; I possess no specimen myself, but have seen it 

 occasionally in other collections. Mr. Alfred Beaumont 

 lately sent me one which he found among wet Sphagnum, 

 near Whitby, in October, 1897.
