168 RIYNCHOPHORA. [ Apion. 
species, black, rather dull, sometimes with a very slight bronze reflection ; 
pubescence fine and very easily rubbed off, so that the upper surface, 
except in fresh specimens, appears almost glabrous; head longer than 
broad, with the eyes not prominent, distinctly punetured, and with the 
space between the eyes a little depressed and finely but distinetly 
striated; rostrum short, scarcely longer than thorax, rather stout and 
straight or almost straight, dull and closely punetured to the insertion 
of the antenne, from thence more diffusely punctured, shining at apex ; 
antenne short and stout inserted near middle of rostrum; thorax about 
as long as broad with the sides rather strongly rounded, widest about 
middle, not very closely but regularly and rather deeply punctured on 
disc, more thickly at sides where the punctuation is often confluent, 
with a small but distinct furrow before scutellum ; elytra oval, rather 
long, with the shoulders scarcely marked, rounded at sides, broadest a 
little behind middle ; strie punctured, distinct, but comparatively fine, 
interstices rather broad, very flat, shagreened; legs black, moderately 
long and stout. L. 13-1{ mm. 
Sandy places ; on species of Sedum, especially Sedum album and S. acre; very 
local, and, as a rule, rare; it has, however, been found not uncommonly at Deal by 
Mr. 8S. Stevens, Mr. Champion, Dr. Power and others; Wimbledon (Power) ; South- 
end; Harwich, one specimen (J. J. Walker) ; Bath; Stretford, near Manchester 
(Reston) ; Scotland, Forth district; the species probably occurs in many other 
localities ; it somewhat resembles small specimens of the common 4. humile, from 
which it may be known by its narrower head, less prominent eyes, more rounded sides 
of thorax, and finer elytral stric. 
Group 22. 
Moderate-sized or rather small species, metallic or black, with short 
and stout straight rostrum (on Rumex, Teucrium and Sarothamnus,
