and thorax finely punctulate, eyes convex and rather promi- 
nent; the thorax transverse, hind angles rectangular; the 
scutellum triangular, obscurely punctulate; the elytra punc- 
tulate, but the punctuation is ill-defined ; the antenna, five 
basal joints palish brown, the others apically infuscate; the 
legs also palish brown, with the bases of the thighs some- 
times dusky. 
This species closely resembles S. hemisphericus, Linn. 
Hab. Bukenji, near Yokohama. Four examples, 29th 
June, 1880. 
Helodes dux, sp. n. 
Ovalis, convexus, nitidus, ‘pubescens ; capite nigro; thorace rufo- 
flavo; elytris nigris, undique punctulatis, griseo-pubescentibus. 
L. 6 mill. 
Oval, convex above, shining, with somewhat long pubes- 
cence; the head black, sparsely punctured, eyes rather 
prominent; the thorax reddish yellow, with pubescence of the 
same colour, anteriorly arched from the posterior angles, base 
bisinuous, behind the neck there is a pellucid space, which 
permits the blackness of the neck to appear through, very 
finely punctulate ; the elytra evenly and wholly punctulate, 
with greyish pubescence; the antenne, three basal joints 
yellowish, others infuscate ; the legs, anterior coxa, and bases 
of the anterior thighs flavous, the rest infuscate, claws and 
terminal segments of the abdomen flavous. 
In this genus the first joint of the hind tarsus is very long. 
Hab. Okamayama, near Hitoyoshi, 8th May, 1881; also 
at Miyanoshita, Nikko, and Fukushima. 
Helodes flavicollis, Kies. 
Helodes flavicollis, Kies, Berl. ent. Zeit. p. 22 (1859), p. 245 (1874). 
Sacodes protectus, Har. Mitt. Miinch. Ver. iv. p. 169 (1880). 
Kiesenwetter decided that this Japanese species was iden- 
tical with the European one, and, as he probably possessed his 
own type and had made a comparison, I have allowed his 
determination to remain. It does not appear that Harold 
knew Lelodes flavicollis, Kies., and in the Munich Catalogue 
he regards the genus Sacodes as synonymic with Helodes. 
The Japanese type of //. flavicollis has red antenne ; but I 
have not seen Kiesenwetter’s original description nor any 
Kuropean example.
