is pale. The upper surface is very shining and quite 
without sculpture, Avhile the Avhole of the raised portion of 
the under siurface is strongly punctiu'ed. 
Common in ponds at Hiogo. 
18. Noterus japo7iicus, n. sp. Convexus, brevior, ni- 
tidus ; elytris fere sine punctis majoribus impressis. Long. 
2 lin. 
Mas, antennis subsimplicibus ; articulo 5** vix incras- 
sato, 8-10 angulo externo superiore acuto. 
Closely alhed to N. Icevis ; just a little shorter and more 
convex than that species, and Avith the punctures of the 
elytra not quite so fine. The structure of the antennae in 
the male is, however, very different from that of N. Icevis. 
They appear at first sight not to differ in the two sexes, 
but when a carefid examination is made it is found that 
the antenna of the male is a little broader than that of the 
female, and that its fifth joint is just a little produced in- 
wardly, and that joints 8 — 10 have each the upper and 
outer angle distinctly acuminate and a little produced. 
Common at Nagasaki. 
19. Laccophilus Lewisius, n. sp. Forma et statura fere 
L. testacei ; testaceus, elytris nigro-lineatis, lineis hand 
flexuosis, aliquantum interruptis ut maculge pallidse ad basin 
et ad marginera videantur. Long. 2^ lin. ; lat. If lin. 
About as long as L. testaceus, but just a little narrower 
and more convex than that species. The maxillary palpi 
are yellow, pitchy at the extremity ; the antennte are 
yellow, with the last joint pitchy, and each of the three or 
four penultimate joints is a little clouded at the apex. 
The head is yellow and unspotted. The thorax is yellow, 
the front margin in the middle and the hind margin have 
an extremely short (i. e. in the longitudinal direction of 
the thorax) black mark ; the front one does not extend 
quite to the inner margins of the eyes, the hind mark is 
not well limited in its lateral extension ; the base of the 
thorax in the middle is formed as in L. testaceus. The 
elytra are yellow, much marked with black ; the black 
marks consist of three or four pairs of lines, the lines form- 
ing each pair meeting together a little before the base ; 
externally, and also towards the extremity, these lines are 
connected with some other more or less linear markings, 
and the whole of these dark marks are so disposed and 
interri\pted as to give an appearance of the elytra pos-
