more narrowed posteriorly, antenne more slender, especially 
the apical joint, second joint pale especially beneath ; entire 
surface rather more shining ; pronotum less deeply sinuate 
posteriorly, its puncturation and that of the elytra finer 
and not so black, membrane narrower and paler ; connexi- 
vum narrowly pale ; all the tibize and tarsi and the apices of 
the femora testaceous; basal joint of the posterior tarsi 
very long, nearly twice as long as the other two together,

(Pachymerus, Lep. ; Calyptonotus, D. & 8.) 
This genus contains numerous species, differing consider- 
ably in facies and colour, which differences have given rise 
to several subgenera, the characters of which I have indi- 
cated in the table of species. It may be known from its 
nearest ally, Beosus, by the greater width of the pronotum 
in proportion to the head and the less prominent eyes, and 
from T'rapezonotus by the long basal joint of the tarsi. 
Head short, triangular, eyes touching or nearly touching 
the pronotum, face in almost the same plane as the vertex, 
except in Rolandri, in which it is distinctly more declivous ; 
antenniferous tubercles only slightly developed, ocelli dis- 
tinct; first joint of the antenne projecting for about a 
quarter to half of its length beyond the apex of the face ; 
pronotum wide, flat, its lateral margins foliaceous, either 
widely pale or very narrowly so or entirely black, more or 
less regularly rounded ; scutellum large; elytra with the 
clavus variously punctured, membrane complete ; legs, front 
femora spined, posterior femora simple or with a small 
spine near the apex in pedestris, tibiw bristly, or nearly 
smooth in Lolandri, basal joint of the posterior tarsi twice 
as long as the other two together, There are twenty-five
