tliorax narrowed ; the antennte not very slender, the last five 

 joints are thickened but not compressed, ninth and tenth equal 

 in size, but not transverse like those of Scaj'hidium ; eyes 

 large and a little prominent; seutellum 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 strije 

 are all punctiforra except the sutural. 



Episcaphium semirufiim, sp. n. 



Oblongo-ovatum, nigrum, nitidum ; elytris, pvgidio tarsisquo rufis. 

 L. 4i-5 miU. 



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

 minal segments, tarsi, and basal joints of antennte red ; the 

 head clearly, evenly, and somewhat closely punctured ; the 

 thorax with the punctures faint and scattered ; the elytra with 

 the sutural stria ])unctate, 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. 



Hah. 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. rujicolle. 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 maculis dcu- 



tato-sinuatis, rubris ; c? tibiis auticis intus minute emarginatis. 

 L. G|-7 miU. 



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

 denticulate fascire ; the head feebly and sparsely punctured 

 between the eyes ; the thorax more distinctly punctate before 

 the basal punctiform line, smoother beiiind 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 ft\scia touches the
