Syn. fmcicollis, Bed. [Col. Bass. Seine, V, p. 310.] (i) 



Ovate, more elongate and less convex than L. suturellus. Head black. 

 Antennae : black or dark fuscovis, with the first three or four joints feiTuginous. 

 Thorax : transverse, bordered, varying in coloiir from a light ferruginous to 

 pitchy red, but never qvxite black, with a more or less pronounced aeneous 

 reflection always present, sometimes almost iridescent, alutaceous, very distinctly 

 and evenly punctured. Elytra : dvdl testaceous, with the suture variably but 

 always distinctly marked in black, generally narrow and abrupt, but sometimes 

 suffused and indeterminate ; there are often other dark linear markings on the 

 elytra parallel with the sutiu-e ; the surface is alutaceous, with distinct confused 

 punctuation, generally rather stronger than that of thorax, but weaker at apex ; 

 apices slightly separately rounded. Legs : testaceous, posterior femora black 

 above, pitchy or testaceous beneath ; first joint of anterior tarsi in <? slightly 

 enlarged ; posterior tibial spurs short. Underside varying from pitchy to black. 

 Wings sometimes present, but more often rudimentary. Length 2 — 2\ mm. 



This species may be distinguished from L. suhirellus by its 

 rather longer oval form, the distinct punctuation of the thorax, and 

 the generally more reddish or testaceous coloration ; from L. suturalis 

 by its form and the more confused elytral punctuation, and generally 

 from all its congeners by the metallic reflection of its thorax. 



Food plants. — Medicago (lucerne) (Allard, Fowler), Onohrychis 

 sativa (H. C. DoUman) . It thus appears to be attached to Leguminosse 

 and probably like other members of the genus feeds on more than one 

 species. L. atricillus ranges throughout the United Kingdom and is 

 generally common. 



Vars. — declivis, Weise : appears to be merely the apterous form ; 

 similis, Weise : a dark form with head and thorax brassy black, and 

 lateral border of elytra black, which can be found in any large series 

 of the species. 



L. STTTURALis, Marsh. [Ent. Brit. p. 201] ; Steph. [Man. p. 296] ; 

 All. [Mon. p. 114] ; Weise [Nat. Ins. Deutschl. VI, p. 966] ; Bedel 

 [Col. Bass. Seine, V, p. 191]. 



Syns. 7iigricollis, Foudr. [Mon. p. 161.] 

 asneicollis, Fald. 



Form oblong ovate, similar to L. atricillus, but rather more parallel-sided. 

 Head black. Antennae : black with first four or five joints testaceous. Thorax : 

 transverse, bordered, black with a slight but distinct bronze reflection, 

 alutaceous, rather weakly but quite distinctly punctured, the punctuation being 

 much less strong than in L. atricillus. Elytra : dull testaceous, with black well- 



(1) Bedel refers to this species in the first part of his work as 7'. atncilla, L., but in the 

 catalogTie says: "Substituez le nom de fuscicollis, Steph., k celui d'atricilla, L. , qui reste 

 6nigmatique," but the Stephensian futcicollis is undoubtedly the form of X, suturellus with 

 red thorax.
