always evenly explanali' from base to iinniediately before its api-x in both 

 sexes wliich, with its usually broad postpetiole and never disliiutly ex- 

 serted terebra, lends it an aspect of its own. 



The species ap])ear nearly confined to south of the Thames; I have 

 seen a single specimen from Yorkshire, and hardly any from Sufiblk. 

 Two kinds, C. riifiiiiana, (ir., and C. alhipalpis, Gr., both standing under 

 the broad genus Limncria in our last Catalogue of 1872, are now known 

 to belong to this genus, but both have almost certainly been erroneously 

 recorded as British; the first was introduced by Desvignes in 1856, occurs 

 in southern Pairope extending north only to the Tyrol, and has been bred 

 by Gaulle from Safyrus siatilinus; the second was included in Marshall's 

 1870 Catalogus and occurs rarely on dry mountain sides from Austria, 

 through Germanv, to near Paris; neither is known in Scandinavia nor 

 Belgium. 



Thomson says "This genus is nearest to ('harops and differs from the 

 other Li/)iiiiri(U both in the more evidently emarginate eyes, the neuration 

 of the wings and in the shape of the abdomen, and the position of the 

 spiracles. Most species are found in sandy meadows."
