Longitarsus. } PHYTOPHAGA. 351 
By sweeping herbage; rare; Purfleet; Littlington and Wicken Fen, Cambridge ; 
Needwood, Staffordshire (Gorham) ; Northumberland district, banks of the Irthing, 
near Gilsland, rare. 
This species appears to be closely allied to the preceding, but is larger, 
with the elytra longer and more oblong and less finely punctured, and 
the posterior femora testaceous or reddish ; there is, however, considerable 
confusion regarding it, and immature specimens of L. pusillus appear to 
do duty for it in collections ; the testaceous colour in life is very leght, 
according to M. Allard, but it appears to become much darker after 
death. 
L. medicaginis, All. According to M. Allard, this insect is 
exactly like L. pusillus both in structure and colour, but it is twice as 
large, and is distinguished by its more convex thorax, which is a little 
compressed in front at each side, and by the fact that the elytra are 
much less obsoletely punctured, the punctuation being fine and close, 
but distinctly visible; the thorax, as a rule, appears to be redder than 
in L. pusillus, and the under surface, as well as the upper, is more 
distinctly punctured. L. 13-2 mm. 
On Ballota nigra and in lucerne fields; very rare; introduced by Mr. Crotch on 
five or six specimens in Mr. Wollaston’s collection, apparently without locality, and 
confirmed subsequently as British by M. Allard some ten years after its introduc- 
tion; Allard gives the lengths of this and DL. pusil/us as 14 and 1} mm. respec- 
tively, and then states that L. medicaginis is twice the size of L. pusillus. 
L. tabidus, F. (verbasci, Panz., Steph., &c.). The largest and most 
conspicuous of our species ; ovate or oblong-ovate, convex, shining, with 
the upper side testaceous or livid-testaceous, the head and suture being 
often ferruginous ; antennz long, testaceous, fuscous towards apex, or 
fuscous with base lighter; thorax with strong margins, almost 1m- 
punctate ; scutellum rather large, smooth ; wings present ; elytra broad, 
with shoulders not very marked, separately rounded at apex, very finely 
punctured ; legs testaceous, with the posterior femora dark at apex, and 
the anterior pairs usually more or less infuscate, posterior tibiz with a 
long and stout curved spur at apex, under-side fuscous or pitchy. 
L. 3-4 mm. 
V. thapsi, Marsh. In this variety the suture is dark, and the 
greater part of the antenne and legs is infuscate ; the under-side is also 
of a darker colour; in structure it agrees with the type, and cannot be 
regarded as a separate species; in the ordinary forms the under-side 
is sometimes red, and varies from this to nigro-piceous ; and the suture of 
the elytra is either unicolorous or more or less ferruginous, 
On Verbascum thapsus ; local, but common where it occurs; Mickleham; Seven- 
oaks; Dover; Amberley; Portsmouth district; Norfolk; Suffolk; Hertford; 
Devon; Swansea; Malvern Hills; Scarborough. 
L. jacob, Wat. (tabidus, Ol., nee F.). Oblong-ovate or ovate,
