Two examples from Oyayama, found with the preceding, 

 but they are evidently not the sexes of one species. 



Rhysodes niponensis, sp. n. 

 Elongatus, piceus, nitidus ; thorace trisulcato, sulcis externis brevi- 



bus. 

 L. 5|-6 mill. 



Elongate, pitchy brown, shining ; head with cephalic lobes 

 nearly touching before the neck, but separated anteriorly by 

 a deep fovea, the frontal raised portion somewhat triangular 

 and terminating before the fovea mentioned in the centre of 

 the head ; thorax above with lateral margin rather elevated, 

 a deep median sulcus and two lateral sulci, which extend 

 from a basal fovea over rather more than half the length of 

 the thorax ; elytra strongly punctate-striate, interstices 

 smooth and a little raised, but in this region there are no 

 important characters. The anterior femora are toothed in 

 the middle on the lower edge, strongly in the male, and 

 scarcely less so in the female. The posterior tibige are swollen 

 before the apices and a little enlarged at the base in the male, 

 simple in both cases in the female. The female also has a 

 large and deep fovea on each side of one abdominal segment, 

 and this character seems common to the genus. This species 

 differs from the other Japanese ones in the shortened outer 

 thoracic sulci, and in this character it is somewhat similar to 

 a species of Clinidium. 



Common in the Hakone district and in Higo. It occurs 

 only under bark of firs {Pinus). 



Rhysodes Lederi, sp. n. 



5 . Niger, nitidus, elongatus, robustus. R. exarato similis at multo 

 major et differt colore, capite, lobo in medio approximate ; pro- 

 noto profunde trisulcato, interstitiis parce punctatis. 



L. ^ mill. 



Hah. Caucasus. 



This species may be placed in the same section of the genus 

 to which R. exaratiis belongs ; but at the same time it is a 

 very different insect. The large size, black colour, and punc- 

 tate thoracic interstices are simple differential characters, but 

 the head is shaped very differently from that of any other known 

 species. The head is largelyswollen posteriorly below the level 

 of the eyes, the cephalic lobes almost touch each other in the 

 centre of the head (not near the neck, as in R. exaratus, Serv.), 

 and the raised portion between the antennae is not constricted in
