Longitarsiis.] PHYTOPHAOA. 351 



By sweeping herbage ; rare ; Purfleet ; Littlington and Wicken Fen, Cambridge ; 

 Needwood, Staffordshire (Gorliaui) ; Northumberland district, banks of the Irthing, 

 near Uilslaud, 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 light, 

 according to M. Allard, but it appears to become much darker after 

 death. 



X. medicagrinis, All. According to M. Allard, this insect is 

 exactly like L. pusillits 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. If -2 mm. 



On Ballota nigra and in lucerne fields ; very rare ; introduced by Mr. Crotch on 

 five or six sptchntns 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 L. pusillut as If and \\ mm. respec- 

 tively, and then states that L. medicaginis is twice the size of L. pusillus. 



It. 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 ; antennae long, testaceous, fuscous towards apex, or 

 fuscous with base lighter ; thorax with strong margins, almost irn- 

 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 tibiae 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 antennae 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 I'erbatcum tkapns ; local, but common where it occurs; Micklebam f Seven- 

 oaks ; Dover ; AmWrley ; Portsmouth district ; Norfolk ; Suffolk ; Hertford ; 

 Devon ; Swansea ; Malvern Hills ; Scarborough. 



Xi. jacobaoae, "Wat. (tabidus, 01., nee F.). Oblong-ovate or ovate,
