Cleonus, however, the genus, which comprises about seventy-five Euro- 
pean species, is exceedingly poorly represented in Britain, only five being 
known, these being all extremely local cr very rare ; the capture, how- 
ever, of a hundred and fifty specimens of LZ. angustatus by Dr. Power, 
at Fairlight, near Hastings, between August 21st and September 2nd, 
1867, rather serves to show that the members of the genus are perhaps 
overlooked (as might naturally happen owing to their habits) and that 
certain of them, and perhaps some new ones, may yet be found in 
numbers in hitherto unworked localities. 
The larvze of several species are known; they do not call for any 
particular notice as far as structure is concerned ; they live and undergo 
their transformations in the stems of various plants (Umbellifere, Poly- 
onacee, Composite, &c.); the female pierces the stem with her man- 
dibles and deposits an egg in the opening, and the young larva when 
hatched begins to feed upon the soft internal parts of the stem ; in the 
case of the large species one larva alone appears to be found in each 
stem, but in the smaller ones several may inhabit one plant; the 
species may be discovered in localities they inhabit by the unhealthy 
appearance of the plants. Perris (Larves des Coléopteres, p. 388) gives 
an account of the habits of the larvee and of the plants on which they 
are parasitic; of our species LZ. paraplecticus appears to be chiefly 
attached to Phellandrium aquaticum and Sium latifolium ; L. tridis to 
Hemlock and Angelica, &c.; ZL. jiliformis to Carduus nutans and crispus 
and species of Cirsium; L. algirus to Cirsium arvense and palustre ; 
and L. bicclor to Erodium cicutartum.* 
I. Scape of anteune plainly longer than the two first 
joints of the funiculus taken together. 
i. Elytra with a sharp prolongation at apex which is 
at least as long (if viewed from below) as the anal 
segment. 
1. Prolongation at apex of elytra long, nearly as long 
as thorax; form slender; eyes prominent . . . UL. PARAPLEOTICUS, L. 
2. Prolongation at apex of elytra short ; form much 
more robust and broader; eyes flat . . . . . UL. rerpis, Ol. 
(turbatus, Gyll.) 
ii. Elytra separately rounded or bluntly angled at apex, 
without prolongation. 
1. Thorax without a definite light band at sides; 
first. joint of funiculus of antennz relatively 
* M. Perris’s lament (I.c. p. 389) over the comparatively small knowledge possessed 
by entomologists concerning such conspicuous species as the Lixi and Larini is 
perhaps worth quoting, as it does not apply simply to French entomologists :— 
“Que d’entomologistes, hélas ! qui, au lieu de pénétrer dans les secrets de la science, 
restent ila surface et la font consister & trouver a grand effort, ne fit-ce que sur 
un seul individu, un caractére qui différencie tel insecte de son voisin, ou & posséder 
beaucoup d’espéces por les aligner avec art dans des beites! Combien d’autres, 
ignorants de la botanique, sont incapables de savourer le charme des relations qui 
lient les insectes aux végétaux! Combien enfin qui, ayant toutes les qualités re. 
quises pour servir et méme honorer la science, gardent pour eux leurs découvertes, 
par nonchalance ou comme sils en étaient jaloux !”’
