B54 PHYTOPHAGA. [ Longitarsus. 
New Forest ; Barnwood, Gloucester ; Repton; Northumberlandand Durham district, 
not uncommon; Scotland, Forth district, aud probably general in the South; Ireland, 
near Waterford. 
L. pellucidus, Foudr. (testaceus, All.). Allied to the preceding, 
from which it may be known by its more prominent shoulders, and the 
more distinct punctuation of the elytra, as well as by having the 
posterior femora more broadly ferruginous, and the breast and abdomen 
pitchy, the latter being obscurely testaceous at apex; the antenne are 
long, scarcely darker at apex, and the apex of the labrum is infuscate; 
thorax rather distinctly punctured ; wings absent or rudimentary; elytra 
not strongly but distinctly punctured, with the shoulders distinct, 
although rounded, and the sutural apical angles very obtuse ; under-side 
somewhat variable in colour, the colour being as above described in 
mature specimens, but lighterin those that are immature. L. 1{-2 mm. 
On Trifolium and Mentha; local, and, asa rule, not common; Mickleham, Darenth 
Wood, Croydon, Birdbrook (Essex), Maidstone, Whitstable, Sheerness ; Ditching- 
ham, Suffolk; Hunstanton, Norfolk; Wicken Fen; Isle of Wight; near Repton 
(W. Garneys). 
Thomson records twenty-six species of this genus from Norway and 
Sweden, but only nine are mentioned in Dr. Sharp’s Scotch list; a 
few have been found in Scotland besides these, and Dr. Sharp remarks 
that the species are probably more numerous than those he records ; it 
is evident, however, that the genus is rare in Scotland, and only sixteen 
have apparently occurred in Northumberland and Durham. 
HALTICA, Geoffroy. (Graptodera, Chevrolat.) 
This genus contains rather more than a hundred species, which are 
very widely distributed, representatives being found in almost all the 
temperate and tropical regions of the world; they are characterized by 
having the anterior coxal cavities open behind, and the thorax furnished 
at base with a transverse furrow, which is, however, not bounded by a 
longitudinal fold on each side; the head is furnished with distinct 
frontal tubercles ; the general form is oblong, and the species are always 
winged ; the colour is blue or greenish-blue ; there are about a dozen 
European species, of which six or seven are British ; they are, however, 
in several instances so closely allied that it is very difficult to determine 
the m with accuracy, and, in spite of its being so small in point of numbers, 
the genus is really one of the most difficult that we have to deal with ; 
the shape of the male intromittent organs seems to afford important 
points of difference, but they are in many cases obscure, and require to 
be studied, if possible, in fresh specimens, or in specimens that have been 
mounted with this organ exserted in such a position that it can easily be 
examined; I have, therefore, not made much use of the characters to be 
drawn from them, but a complete table is given by Weise (Naturgesichte 
der Insecten Deutschlands, vol. vi. part v. page 829), to which the 
student of the group is referred ; the chief distinctions lie in the presence
