Nagasalci. Also Korea and Kiu-Kiang on the Yang- 
tsze, China. Abundant. 
Precisely similar in shape, sculpture and colours to the 
European //. limhatus, except that the elytra of the $ have 
a blue or green gloss. The base of the thorax over a wide 
space is minutely punctured, the punctuation extending on 
each side far towards the disk; this character distinguishes 
it from H. luteicornis, with Avhich it agrees better than 
with H. limhutus in the rectangular hind angles of the 
thorax. The setiferous puncture of the elytra lies very 
far back ; the striae are deeper towards the apex, and the 
interstices more conxex ; the extreme lateral margins of 
the elytra are rufescent. The female has silky-opake 
elytra, with a shght greenish gloss. 
//. relucens, n. sp. 
Oblongo-ellipticus, piceo-niger in utroque sexu nitidus, 
elytris \4rescenti-relucentibus; palpis, antennis, thoracis mar- 
gine laterali pedibusque fulvis ; thorace transverso, antice 
angustato lateribus ])arum arcuatis, angulis posticis sub- 
rotundatis, basi toto lateribusque crebre punctatis ; elytris 
fortiter striatis, interstitiis subplanis tertio unipunctato.

Nagasaki (many examples) ; also in China, at Foochow. 
Similar to H. tinctulus in facies and colour, biit distin- 
guished by the thorax having the posterior angles very 
obtuse and almost rounded, and by the $ being quite as 
])olished as the $ ; the surface of both being very glossy. 
The stria3 become sulci towards the apex, and the inter- 
stices narrow and convex. The tliorax is as wide anteriorly 
as the elytra, but narroAvs slightly behind.
