If Kirby’s views of the limits of genera are to be carried 
out consistently, this species will require to have a new 
genus erected for its reception. (Cf. Journ. Lin. Soc., xvii., 
p. 53). 
Hab.j Nagasaki, Japan {Geo. Leivis). 
Panthalis, gen. nov. 
Antennae 9 -jointed (including the annellus, which is small 
and broader than long) ; the 3rd joint a little longer than 
the fourth ; the others subequal to the last, which is one- 
half longer than the penultimate; stout, of nearly equal 
thickness throughout ; situated well up on the face. Head 
much broader than long, concave in front and behind ; the 
front excavated, the excavation not reaching" to the foremost 
ocellus ; the face keeled below the antennae ; cheeks mar- 
gined ; eyes large, oblong, bare. Prothorax longish, nar- 
rowed in front; mesonotum flattish, parapsidal furrows 
narrow, but deep; pleurae deeply and widely excavated 
obliquely in the middle; scutellum large, flat, of nearly 
equal width throughout, the apex rounded ; at the sides, at 
the base, deeply excavated; metathorax scarcely one-half 
the length of the scutellum ; keeled down the centre. Abdo- 
men subsessile ; the first segment longer than the following 
three united ; the third is produced into a broadly triangular 
sharp point in the middle above ; the fourth similarly pro- 
duced, but blunter. Ovipositor longer than the abdomen, 
closely clasped by the segments ; the sheaths closely united ; 
from the centre above and laterally is developed a large 
plate, which becomes gradually larger to the apex, which is 
rounded. The lateral plates curve slightly downwards. 
They are shining, obscurely ribbed, and bear short stiff, 
widely-separated hairs; the edges are fringed with hair. 
Legs slender; coxae large; spurs short, slender. Ulna 
elongated, thick ; cubitus curved, thick, three times longer 
than broad. 
The affinities of this genus lie with Belonea, Prionopelmaj
