line of points before the scutellum is less defined, and extends 

 transversely without any perceptible angle. 

 Hab. Nagasaki ; from an old tree in May. 



Xuthia niponia, n. sp. 



X. elongata, cylindrica, opaca, rufo-testacea ; capite haud grosse 

 punctato ; thorace grosse punctato, sulcis tribus longitudinalibus, 

 inaequalibus, vix conspicuis notato ; elytris striis angustissimis 

 elevatis, interstitiis seriatim grosse punctatis. L. 1| lin. 



The thorax is roughly punctate, with an uneven depres- 

 sion in the median region, and one on each side, rather more 

 defined, running laterally. The sutural stria of the elytra 

 is for about the basal fifth of the wing-case separated from 

 the second stria by an interstice of the same width as the 

 remainder ; but nearer the apex it closes towards the suture, 

 with which it then again runs parallel. It is smaller than 

 any of Mr. Pascoe's species, as might be expected, from its 

 northern locality. 



Hab. Nagasaki. 



Teredus politus , n. sp. 



T. ekmgatus, cylindricus, niger, nitidus ; capite thoraceque distincte 

 punctatis ; elytris striato-punctatis ; antennis pedibusque rufis. 

 L. If lin. 



Shorter and broader than T. nitidus, F. Although the 

 colour and punctation of these two species do not materially 

 differ, the Japanese one may hereafter form a new genus, the 

 club of its antenna consisting of one large terminal ovate joint 

 preceded by two small ones. 



Hab. South Japan. 



Macrodorcus Vanvolxemi, n. sp. 



M. elongatus, parallefus, niger, subopacus ; mandibulis capite vix 

 longioribus, in medio unidentatis ; clypeo transverso, medio pro- 

 minulo ; capite thoraceque subtilissime punctatis ; abdomine subtus 

 distincte punctato. L. 9 lin., mandib. 6 If. 



Amongst Japanese species, allied to M. opacus, C. Waterh. ; 

 it is, however, more parallel, and the punctation of the abdo- 

 men is general and distinct. The elytra are finely and clearly 

 punctured on the disk and near the suture, the points at inter- 

 vals assuming the form of irregular strise ; but at the outer 

 sides the punctation is deeper and more dense. The clypeus 

 is raised to a point in the centre only, the outer angles being 

 obtuse.
