5 (4), Elytra red, sometimes darker in a small and badly defined area near 



scutellum ; size smaller ; peniiltimate ventral segment of t? tri- 

 angularly excised at apex, and furnished with a long tooth-like 

 process, which is ciliated at apex, on each side of this excision. 

 Length, 6.5-7.5 mm L. Isevipenne, Heer. 



6 (3). Penultimate ventral abdominal segment of S with a row of converging 



black hairs (crests of Rey) on each side of central longitudinal 

 furrow. $ with dorsal apical segment not ridged. Elytra normally 

 in part, or entirely, red. 



7 (8). Upperside of head more diil'iisely and finely punctured than that of 



thorax ; coxae usually red, except at base ; elytra either entirely red, 

 or with only a small and badly defined black area near scutellum ; 

 thorax longer in proportion to its breadth than in the following two 

 species. J with penultimate ventral segment much as in geminum. 

 Length, 7.5-8.5 mm L. ripicolo,, Czwal., horeale, Rey, nee Hochh. 



8 (7). Upperside of head almost as closely and deeply punctiu'ed as that of 



thorax ; coxae nearly always black or pitchy ; elytra with the black 

 coloitr more extensive than in ripicola ; average size larger. 

 Length, 8-9 mm. 



9 (10). Underside of head more diffusely and finely punctured. S with the 



apex of penultimate ventral segment slightly excised in a curve, 

 often nearly triuacate The form with almost entirely black elytra 

 is the var. volgense, Hochh L. geminum, Kraatz. 



10 (9). Underside of head more closely, and usually more coarsely, punctured. 

 <J with the apex of penultimate ventral segment sharply tri- 

 angularly excised. The limits of the Itlack and red colour of the 

 elytra are usixally more strongly defined than in the last species. 

 The form with nearly lilack elytra is the var. fraudtdentum, Ganglb. 



...L. elongatum, Linn. 

 L. fnlvipenne, Grav., varies in the leiijjjtli of the elytra accordino- 



to the development of the wings. It is easily separable from the other 



species in both sexes. 



L. brunnipes, Fabr. The above remarks apply equally to this 

 common species. 



L. Ixvipenne, Heer. A ? specimen taken by Mr. W. E. Sharp 

 was referred doubtfully to this species by me, and was subsequently 

 corroborated by Herr Grauglbauer (Ent. Mo. Mag., xlii, 55). The 

 females of leevipenne and ripicola are exceedingly difficult to separate ; 

 they differ in the colour of the coxae and a little in size. The capture 

 oi Q. t$ Isevipenne is very desirable. Mr. Tomlin has a note of some 

 specimens which he referred to the ^ of this insect (Ent. Mo. Mag., 

 xliii, 136), two of which I have seen. They are certainly not L-evipenne, 

 but like that species they are without the " crests " on the penulti-
