A curious species of a genus allied to Urorys has been found 
lately on Oshima, the largest island of the Ruikiuan group,

PANELUS, gen. nov. 
This genus is established for the reception of a small 
species in many respects similar to a species of Scatinus and 
Saphobius. Body somewhat ovate; terminal joint of max- 
illary palpi elongate; the mentum small and distinctly in- 
cised anteriorly ; the head, eyes visible from above, clypeus 
bidentate on the anterior edge, frontal suture invisible, lateral 
edge minutely notched ; the mesosternum pointed anteriorly ; 
the thorax, anterior angles largely excavated for the recep- 
tion of the antennal clubs; the legs, anterior tibiz feebly 
dilated apically, apex without tarsal grooves, intermediate 
and posterior tibiz bent, not dilated towards the tarsi, ante- 
rior tarsi very short. In the figure the tarsi are drawn a 
little too long; the figure represents the form of the inter- 
mediate tarsus, which, like the hind tarsus, is stout at the 
base.
