half the length, maxillae very long and very slender, inner lobe with 
an apical inner fringe of short hairs, upper lobe as long as the maxillae, 
compressed, slender, fringed with hairs, ending in a long pencil of hairs, 
and either slightly longer, including the pencil of hairs, than the maxillary 
palps, or very much longer ; maxillary palps very long, the ultimate joint 
sub-cylindrical or sub-fusiform, truncate at the tip ; mandibles long,* 
arcuate at the tip ; labrum very long, elongate ovate, epistome transverse, 
■arcuate in front, eyes large, lateral, head plainly quadrate behind the 
eyes ; antennae shorter than the body, moderately slender, all the joints 
sub-cylindrical, and of nearly equal length, even the second basal one 
which is not nodose ; prothorax sub-quadrate or rounded laterally and 
attenuate in front, base distinctly marginate ; scutellum moderately small, 
obtusely triangular ; elytra sub-parallel, slightly sinuate laterally, or 
somewhat attenuate behind ; legs and tarsi long, slender ; claws cleft into 
two, upper tooth moderately arcuate, strongly pectinate inwardly, lower 
claw filiform ; inner spur of hind tibise short but robust. 
The genus is characterised by the extremely long upper lobe of the 
maxillae, which is always longer than the maxillary palps, is briefly 
hairy, penicillate at apex and greatly resembles in some species that of 
Nemognatha and Gnathium. 
The type of this genus is Zonitoclema viridipemiis, Fabr. and Casteln. 
But I am not sure of the absolute identity of this species, and were it to 
prove erroneous Z. fahrcei {collaris, Fahr.) would be the type. 
Key to the Species. 
A^. Body black, with the prothorax reddish or red ; elytra green or blue. 
B^. Abdominal segments partly red ( <? ) or totally red ( ? ). 
Inner lobe of maxillge, including the apical pencil of hairs, one-third 
longer than the maxillary palps ; prothorax transverse, sub- 
trapezoidal viridipennis. 
Inner lobe of maxillge slightly longer than the maxillary palps ; 
prothorax ampliate rounded laterally, slightly attenuate in front parentalis. 
Inner lobe of maxillae twice as long as the maxillary palps ; 
prothorax ampliate rounded laterally, plainly attenuate in front . . fahrcei. 
B^ Abdominal segments not red. 
Inner lobe of maxillae hardly longer than the maxillary palps ; 
prothorax ampliate rounded in the centre, not much attenuate in 
front proximus. 
A^ Body rufous, with the elytra green.
