inter medium et apicem ; antennis pedibusque plus minusve 

 obscure rul'escentibus. Long. 5| lin. $ . 



Hiogo, three examples. 



Of the same ashy-green colour as C. 4-punctatus, F., but of 

 much narrower and more cylindrical form. The antennas are 

 slender and half the length of the body in the female. The 

 thorax is long, very gradually narrowed in front and abruptly 

 narrowed near the base. The elytra are sharply and obliquely 

 truncated, with the exterior angle dentiform ; each has, behind 

 the middle, two transverse black spots, the first a little after 

 the middle, and the second nearly midway between the first 

 and the apex ; near the base there are also two small black 

 specks, one near the scutellum, the other on the humeral callus. 

 The legs are long and slender ; and the hind femora reach the 

 tips of the elytra. 



Clytanthus dtminutus, n. sp. 



C. parvus, cylindricus, angustus ; niger, elytris macula communi 

 pone scutellum, altera utrinque discoidali longe ante medium, 

 fascia pone medium et margine apicali griseo-albis ; antennis 

 pedibusque piceo-rufis. Long. 2 lin. 



Nagasaki, two examples. 



Smaller and much narrower than C. massiliensts, Linn. , 

 more cylindrical. Antennse filiform, as long as the body ; 

 third joint twice as long as the fourth. Front broad and 

 plane, without ridges ; antenniferous tubercles slightly ele- 

 vated. Thorax oblong-ovate, rather more narrowed behind 

 than in front, closely punctured ; the base on each side bor- 

 dered with light grey. Scutellum black. Elytra cylindrical, 

 transversely truncated, exterior angle dentiform ; a sutural 

 spot behind the scutellum, a discoidal spot behind, a fascia 

 remote from this behind the middle, and the apical border 

 light grey. The sides of the breast and abdomen are spotted 

 with light grey. The legs are moderately elongated, the 

 thighs rather thickened.
