Mr. G. Lewis on new Japanese Histeride. 133 
abdomine subtus plano; propygidio utrinque sulcato, pygidio 
impunctato. L.7 ad 8 mill. 
This species is like H. elongata, but it has no tuberele on the 
head, nor is there an arched sulcus in the third (the broadest) 
segment of the abdomen beneath. The sides of the thorax 
are more rotundate, and each elytron has one short stria at 
the base. These characters, joined to the broader outline and 
facies generally, are of good specific value. 
I obtained a series of twenty specimens in the moist forests 
of Higo in May, chiefly at Konose and Yuyama; it is the 
most tropical form of the genus in Japan, and is found under 
the bark of both the hard-wooded evergreens and the deciduous 
trees. 
Hlololepta amurensis, Reitter. 
Hololepta amurensis, Reitter, Deutsche ent. Z. xxiii. (1879) p. 218. 
The male of this species has a deep thoracic fossa. It was 
described by Herr K. Reitter from Amurland, as the trivial 
name indicates, and I found it commonly in all the forests of 
Japan of moderate elevation. I have beaten it in plenty near 
the Junsai lake in August, off the branches of Salix infested 
with Cossus. 
Note.—Some of the Histerids of the Hololepta group with 
simple mandibles are not strictly entomophagous in the imago 
state; and this is particularly the case with H. amurensis, which, 
I believe, feeds exclusively on exuding sap. Hololepta elon- 
gata, which I have taken plentifully in Ceylon and other 
places, is probably (with H. parallela) wholly dependent on 
smal] soft-bodied larva for food, and I have never seen H. 
depressa at sap. 
Platysoma pint, n. sp. 
Ovale, subconvexum, nigrum, nitidum, leve; fronte clypeoque con- 
cavis, stria transversa integra; pronoto stria non interrupta ; elytris 
striis 1-4 integris, 5 breviori, 6 nulla; propygidio biimpresso, 
pygidio margine elevato, grosse punctatis; antennis pedibusque 
brunneis. L. 5 mill. 
Closely allied to H. odiosum (Marseul’, Cand.), but smaller ; 
with a different system of dorsal striation. 
Occurs under pme-bark in the warmer parts of Japan; Higo 
and Isei are the chief localities for it. 
Platysoma vagans, n. sp. 
Oblongum, parallelum, subconvexum, nigro-piceum ; fronte sub- 
concayva, stria recta; pronoto punctulato, stria integra; elytris
