Elongate, bluish black, shining; the head impressed 
between the eyes and very finely punctulate; the thorax 
about as long as wide, arched anteriorly ; the elytra rather 
long and parallel, densely punctulate and finely rugose; the 
antenna long and Jax in male, not serrate, female articula- 
tions much shorter and thicker, three or four basal joints 
obscurely testaceous on the under surfaces; the legs rather 
long, black or bluish black, anterior tibiz of male longer 
than those of female and somewhat bent ; male anterior tarsus, 
second joint dentate at its apex, third affixed to its base and 
resting at right angles to it. 
The anterior tarsus of male is formed like that of A. elegans, 
Fairm., a species from Gibraltar. This character is much 
less observable in A. japonicus, Kies., a species which differs 
also in having serrate articulations to the antenne. 
Hab. Nagasaki. Two males and two females. 
Dasytes constrictus, sp.n. (Pl. VI. fig. 9.) 
Nigro-ceruleus, nitidus, breviter griseo-pubescens ; capite thoraceque 
dense punctatis ; antennis basi obscure brunneis ; pedibus nigris. 
L. 43 mill. 
Blackish blue, densely punctate, with short grey pubes- 
cence ; the head densely punctate and constricted behind the 
eyes; the thorax similarly punctate, narrowest anteriorly, 
widest behind, without lateral margin; the scutellum small ; 
the elytra, punctuation less dense than that of the thorax, 
without strie; the legs black; the antenne nearly monili- 
form, not enlarged on the inner side, second and third joints 
brownish, basal joint less clearly so. 
The shortness of the antennz and the absence of a thoracic 
marginal carina may make it desirable later to found a genus 
for this species. 
Hab. Hitoyoshi and Yuyama in Higo. Two examples. 
CELSUS, gen. nov. 
This genus must be placed near Dasytes; but I do not 
know any species of similar facies to the insect on which it is 
founded. It is to be regretted that my specimen is unique. 
Maxillary palpus rather long, with the terminal joint large 
and securiform; the antenne, first joint robust and longer 
than the second, but not larger in girth, second smaller and 
bulbiform, third to sixth very small, third largest; seventh 
to the tenth larger than the second, dilated on the inner edges, 
and all coequal ; terminal joints similar to the tenth in width,
