Smermus (?) bimaculatus, n. sp. 



S. sublinearis, fulvescenti-fuscus, subtiliter incumbenti-pubescens, 

 elytris utrinque medio macula elongata obliqua atro-fusca; capite 

 thoraceque angustis, punctulatis ; oculis vix prominulis, tuberi- 

 bus antenniferis elevatis subparallelis, punctulatis, apice breviter 

 sinuatim truncatis; antennis longissimis, sparsim ciliatis, rufo- 

 testaceis, articulis apice nigro-fuscis, scapo thorace longiore, grada- 

 tim clavato. Long. 4|-6 lin. 



Maiyasan ; rare. 



Agrees with Laeordaire's definition of Smermus, except in 

 the form of the scape, which he defines as " en cone renverse* :" 

 whereas in the present insect it is gradually enlarged into an 

 elongated club. The cheeks, too, are only moderately elon- 

 gated. I do not venture to institute a new genus on these dif- 

 ferences of structure. The thorax is elongated, narrow, and 

 cylindrical, except a slight tumescence of the sides in the 

 middle and at the anterior and posterior extremities. The an- 

 tennas are four times as long as the body in some examples, 

 and, as in the type of the genus, the eleventh joint is as long 

 as the ninth and tenth taken together. 



Calamobius japonicus, n. sp. 



C. linearis vix convexus, fusco-piceus, subtiliter pubescens, crebre 

 punctulatus ; antennis corpore plusquam duplo longioribus, arti- 

 culis basalibus longe hirsutis, scapo thoracis basin haud attin- 

 gente ; elytris per suturam depressis, apicem versus haud declivibus, 

 apice obtusissime breviter oblique truncatis ; tibiis rufo-testaceis. 

 Long. 3-6 lin. 



Nagasaki. Crepuscular or nocturnal in flight. 



Similar in size and shape to Cat. gracilis, but not agreeing 

 with it in generic characters, according to Laeordaire's defini- 

 tion. This is the case principally in regard to the scape of the 

 antennas, which is relatively much shorter; the scape and 

 several basal joints are clothed with long hairs on all sides. 

 The head is similar in shape, the antenniferous tubercles being 

 only moderately elevated, oblique, and rather distant ; but the
