variable, but always move or less coarse and confused, weaker at apex, apical 

 angles very feebly rounded. The external apical border of elytra and the pygi- 

 diiuxi bear long- white cilia, tliose of the latter being visible through the slight 

 dehiscence of the elytral apices. Legs : testaceous with posterior femora some- 

 times concolorous.but more usually dark brown; first joint of intermediate and 

 anterior tarsi in ^ very plainly enlarged. Underside black. 



According to Fouclras both sexes are apterous, but we have seen 

 a (J speciuien taken in Kent completely winged. Length, 2 — 2^ mm. 



This species is readily separable from all our other British Longi- 

 tarsi by the possession of the apical cilia above described, which, how- 

 ever, appear to be often more or less abraded. 



Otherwise it can be distinguished from L. luridus by its broader 

 and more oval form, and generally lighter and more constant colour ; 

 from L. rnhiginosus, by its miich shorter antennoe, and from both by 

 its weaker elytral punctuation. 



It probably lives on a marsh plant. Commander Walker has 

 found it apparently associated with Aster trtpolinm in Sheppey, but 

 if this be a food-plant of the insect at all, it certainly cannot be 

 so exclusively. 



Its range appears to be restricted to inland and littoral fens and 

 marshes. We have seen specimens from Wicken, King's Lynn, and 

 Sheppey, and there are records from many other localities in England, 

 but owing to the confusion in which the nomenclature of this and the 

 next species is involved, these records may perhaps be open to some 

 doiibt.

The synonymy of this and the preceding species is exceedingly 

 confused, intricate, and uncertain. There appears to l)e some difPerence 

 of Continental opinion as to what species Duftschmidt's names really 

 denoted (see Bedel. Col. Bass. Seine, V, p. 307). 



We have with some hesitation, although at variance with the 

 latest European catalogue, adopted the name L. rasfaneus, Duft., for 

 the ciliated, and retained L. luridus, Scop., for our common species,
