preceding by its darker and more or less ferruginous colour, smaller size, 
rather stouter antenne, and more closely punctured thorax and elytra ; 
the latter are much narrower, with the punctuation arranged in distinct 
rows towards base, and have a less gelatinous appearance; from L. 
flavicornis and pellucidus it may be known by its smaller size and 
much stouter antenne, of which the five or six apical joints are blackish ; 
it is also much more coarsely punctured than the latter species. L. 14- 
1f mm. 
By sweeping herbage; very rare; Caterham (Champion); Mr. Rye also records 
two specimens from his own collection without locality ; it is very much to be 
regretied that so many valuable localities are lost to us, owing to the fact that Mr. 
Rye never labelled or numbered his specimens. 
L. cerinus, Foudr. Oblong-ovate, reddish or ferruginous-testaceous, 
labrum brown, under-side ferruginous; antenne testaceous, darker 
towards apex ; thorax finely punctured ; wings present; elytra mode- 
rately strongly and somewhat rugosely punctured; legs testaceous, 
posterior femora darker at apex; from the preceding spe ies it may be 
known by its very finely punctured thorax, and from L. bal/ote, which 
it considerably resembles, it may be distinguished by having the under- 
side ferruginous instead of black, and by the somewhat less strong 
punctuation of the elytra, which appears to be somewhat variable as 
regards its arrangement. L. 1} mm. 
By sweeping herbage ; very rare; Mickleham (Rye); Dr. Ellis records it doubt- 
fully from Wallasey, near Liverpool; the character of the ferruginous under-side is 
very misleading, as, unless the specimens are fully matured, those species which are 
distingnisned by having the under-side pitchy black appear to have this part more 
or less reddish; it must, therefore, be cnly considered in conjunction with other 
characters, and if possible in a number of specimens ; in species like the present, of 
which only one or two British examples are recorded, it is extremely hard to deter- 
mine with exactness their real identity. 
L. flavicornis, Steph. (rubiginosus, Foudr.). Ovate, convex, upper 
and under surface ferruginous, mouth pitchy, head antenne and legs 
testaceous, posterior femora darker; antenne long, slivhtly paler at 
base ; thorax a quarter broader than long, evenly rounded at sides, 
convex, closely and strongly punctured; scutellum triangular; wings 
absent ; elytra at base scarcely wider than base of thorax, dilated in 
middle, and narrowed behind, forming a regular oval, shoulders com- 
pletely effaced, apices separately rounded, punctuation deep and strong ; 
the entirely testaceous antenne and strong punctuation will separate 
this species at once from all our other members of the genus. L. 21— 
2+ mm, 
On Eupatorium cannabinum, &e.; rare; Mickleham ; Claygate ; Cowley ; Ditch- 
ingham, Suffolk; Wicken Fen; Hastings district; Lee Valley, North Devon ; 
Barnwood, Gloucester; Repton. 
This is the last of the more coarsely punctured species; in those that 
follow the punctuation is either fine, very fine or alinost absent, that of 
L. rutilus alone being intermediate,
