some Japanese Scaphidiitlie. 291 



thorax narrowed ; the antennaj not very slender, the hist five 

 joints are thickened but not compressed, ninth and tenth equal 

 in size, but not transverse like those of Scaphidium ; eyes 

 large and a little prominent ; scutellum semicircular poste- 

 riorly ; the thorax with transverse line of punctures ; the 

 mesosternum is much less wide than in Scaphidium and the 

 anterior process is much more produced, has parallel sides, 

 and is carried forward in the form of a keel ; the meta- 

 sternum is margined with an arched stria. The elytral striaj 

 are all punctiforra except the sutural. 



Episcaphium semirufum^ sp. n. 



Oblongo-ovatum, nigrum, nitidum ; elytris, pygidio tarsisque rufis. 

 L. 4i-5 mill. 



Oblong-oval, convex, shining, black, with elytra, abdo- 

 minal segments, tarsi, and basal joints of antennse red 5 the 

 head clearly, evenly, and somewhat closely punctured ; the 

 thorax with the punctures faint and scattered ; the elytra with 

 the sutural stria punctate, complete, and continuing along the 

 base, surface with punctures arranged in lines more or less 

 broken, the rows nearest the humeral angles being the best 

 defined ; the legs black, without sexual differences. 



Hob. Nikko, Kiga, and Miyanoshita. Not very common. 



Note. — I took a series (seventeen specimens in all) in 

 Kiushiu, at Yuyama, Ichiuchi, Konose, and other places with 

 the thorax, except a narrow rim behind the neck^ red^ to 

 which I wish to apply the name of A. riificolle. It may be a 

 variety, but, if so, it is a constant one in South Japan. 



The five species following have maculate elytra : — 



Scaphidium emarginatum^ sp. n. 



Ovatum, convexum, nigrum, nitidum ; elytris duabus maculia den- 



tato-sinuatis, rubris ; <S tibiis anticis intus minute emarginatis. 

 L. 6^-7 mill. 



Oval, convex, black, shining, each elytron with two red 

 denticulate fasciae ; the head feebly and sparsely punctured 

 between the eyes ; the thorax more distinctly punctate before 

 the basal punctiform line, smoother behind it ; the elytra with 

 a somewhat stronger punctuation, especially in the dorsal 

 region, sutural stria rather fine and punctulate, deeper with 

 large punctures along the base ; anterior fascia touches the
