L. fnscfdm, Kutscli., was described from British examples sent 

 him by Gr. E. Waterhouse in 1862. We have been enabled, by the 

 conrtesy of Mr. E. A. Waterhouse, to examine the type specimens now 

 in the " Waterhouse" Collection, and we believe this also to be merely 

 one of the forms of the polymorphic L. luridus. The " species" does 

 not appear to have been recog-uised from anywhere else in Europe, and 

 the European CataloLfue (Heyden, Reitter, and Weise, 1906), gives 

 fusculus, Kutsch., merely as a doubtful synonym of L. luridus, Scop. 

 The Waterhouse specimens differ from the more usual forms of 

 L. luriduit in being- smaller and more parallel-sided, with the elytra 

 lighter in colour than the thorax, and with the punctuation closer and 

 less coarse, Init any fairly large collection of L. Ivridns will show a 

 complete gradation to such forms. 



An examination of the genitalia of both sexes of these three 

 forms, " hruiinens,''' "Inridiis,'' and "fusculus,'' which Mr. H. Britten 

 has been good enough to dissect out for us, reveals no difference what- 

 ever between them. This fact of itself is of course insufficient to 

 prove their specific unity, l)ut it certainly renders impossible their 

 separation on these characters.

Of a rather long oval shape. Entirely testaceons, lighter or darker. Head : 

 dark testaceous, vertex often Ijlack. Antenna' : almost as long as body, light 

 testaceons, often slightly dusky towards apex but never black. Thorax : dis- 

 tinctly transverse, bordered, punctuation variable, but xisually fine and remote, 

 alutaceous or smooth between the puuctui-es. Elytra : coarsely, rugosely and 

 sometimes subseriately punctured, very faintly alutaceous, somewhat sunilar to 

 those of L. luridus ; apices separately rounded ; sutirre sometimes faintly rufes- 

 cent. Legs : pale testaceous, posterior femora usually, l)iit not alwaj-s, some- 

 what darker, first joint of anterior tarsi in J liardly enlarged. Underside 

 ferruginous. Winged. Length, 2 — 2.\ mm. 



The long, light coioiu'cd antenna.', comliined with the coai'se elytral piuictua-

 has taken it on G. sejiiuni at Symonds' Yat and Kerne Bridge, and on 



< In the " Entoinologist," No. '»'<* (May, 1010), Dr. Sliari) criticises Weise in vegiird to tlii.s or 

 these siieeies. The latter aiitlim- regards A, bnnufus as a winged, and I. laritlu-i an apterous, 

 form, extending nnah furtlier nortli than I. brunneus. Dr. Sliarp appears to di.sscnt from this 

 view, but holds that the final solution of the problem i.s still to seek.
