&c.), the epistoma not clearly defined ; eyes large, subtransverse, distant ; prothorax transverse, strongly 
margined ; scutellum triangular ; elytra long, distinctly margined, the humeri but little prominent, regu- 
larly punctate-striate ; first joint of the anterior and intermediate tarsi long, in the male broadly expanded 
and dilated, the outer third excavate above for the reception of the second joint; first joint of the posterior 
tarsi very much longer than the second and third united ; tibiae smooth on their outer edge, the outer apical 
angle of the anterior pair with two fine teeth (as in many Platydemata) ; prosternum horizontal, the apex 
a little produced and received by the concave V-shaped mesosternum ; trochantin distinct; epipleure 
extending to the apex of the elytra ; form elongate ovate; surface opaque. 
A new genus is necessary for the reception of this somewhat remarkable species, 
which will be recognized amongst its all... oy its elongate oval form, and by the 
dilatation and extension of the first joint of the anterior and intermediate tarsi. This 
may or may not be a sexual character; in Lelegeis the first joint of the anterior tarsi 
is similarly enlarged. The single known species, of which one (male) example only 
has been received as yet, forms one of Herr Hoge’s interesting discoveries tn Mexico. 
1. Paniasis dilatipes. (Tab. IX. fig. 22,2.) 
Elongate ovate, moderately convex, dull black, opaque. Head transversely impressed in front, shining, coarsely 
and rather closely punctured, the anterior margin reddish brown ; antenne with the two basal joints and 
the outer half of the apical one red; prothorax transverse, the sides straight from the base to a little 
before the middle, thence rounded and narrowing to the apex, the base bisinuate and with a very shallow 
longitudinal impression on each side, the apex deeply emarginate, the anterior angles prominent but 
obtuse, the surface regularly, very evidently, and somewhat sparingly punctured; elytra long, very 
slightly rounded at the sides, a little wider than the prothorax at the base, widest about the middle, 
finely and shallowly punctate-striate, the interstices flat and exceedingly finely and sparingly punctured ; 
femora and knees reddish brown, the tibie black, the tarsi red; beneath black, shining, sparingly 
punctured, the epipleure reddish brown from the middle. 
Length 6 millim. (<.) 
Hab. Mexico, Jalapa (Hoge). One example. 
LELEGEIS. 
Mentum trapeziform, deflexed at the sides; last joint of the maxillary palpi broad, subsecuriform; antennz 
reaching a little beyond the base of the prothorax, joints 5-10 about equal in length, subtriangular, and 
feebly serrate within, the third joint the length of, but much narrower than, the fourth, the eleventh 
joint a little narrower but much longer than the tenth, and bluntly rounded at the apex; head very short, 
deeply sunk into the prothorax, the space before the eyes very narrow, the epistoma short, truncate in 
front and not defined ; eyes very large, oblique, separated by a narrow space, partly hidden by the front 
margin of the prothorax ; prothorax very short, strongly transverse ; scutellum large, transverse; elytra 
wider than and rather more than three times as long as the prothorax at the base, rather strongly mar- 
gined, the humeri prominent, the sides almost straight to beyond the middle, broadly rounded at the 
apex, regularly punctate-striate ; tibie serrate on their outer edge, the two hind pairs much more 
coarsely ; the anterior tibie also armed with two very fine teeth (placed close together, at some 
distance before the apex), the intermediate pair curved, very obliquely cut off at the apex, and also serrate 
on their inner edge, the posterior pair straight and also (finely) serrate within ; first joint of the anterior 
tarsi the length of the apical one, greatly thickened and dilated, and feebly sub-bilobed ; first joint of the 
posterior tarsi long, longer than the second and third together; epipleure extending to the apex of the 
elytra, concave within ; trochantin distinct ; mesosternum V-shaped (the prosternal process appears to 
be broken off); intercoxal process rounded ; form oblong ovate, broad, subparallel; surface shining. 
This genus contains a single species from Mexico. I can suggest no near ally to this 
insect, which will be readily identified by the characters given ; its affinities, however, 
are clearly with Platydema.
