basi sparsim punctato ; elytrorum sutura marginibusque testaceo- 

 rufis ; tibiis tarsisque piceis, coxis rufis. L. 2-2 g lin. 



Easily known from T. anckomenoides, Bates, by its less con- 

 vex form, smaller size, and the red sutures of the elytra, the 

 strise of which are more lightly impressed. 



Hab. Hiogo, very common in marsh lands. 



Ptomascopus plagiatipennis, n. sp. 



P. niger, subnitidus, undique punctatus ; elytris singulatim plaga 

 sanguinea notatis ; abdomine, corpore subtus, pedibusque griseo- 

 pubescentibu8. L. 7 lin. 



More robust than P. morio, Kraatz, with the punctuation 

 larger and much more distinct, that of the elytra being of a 

 somewhat larger grade than that of the thorax. The red 

 blotch is broad, beginning near the apex of the scutellum, 

 extending outwards to the edge of the elytra (leaving the 

 suture black), and, then turning upwards, occupies half the 

 base at the humeral angle : towards the apex there is a 

 narrow streak of red filling the space between the carina and 

 exterior margin. 



Hab. Kagoshima ; also Pekin. 



Note. — I have a species of this genus from the Amazon river : — 



Ptomascopus carbunculus, n. sp. 



Niger, nitidus ; capite subtiliter punctato ; thorace elytrisque sparse sub- 

 tilissitne punctatis ; subtus griseo-pubescens. L. 5-5^ liu. 



Nodynus leuco-fasciatus, n. sp. 



N. oblongus, depressus, niger, nitidissimus, fronte punctulata ; pro- 

 noto antice et ad latera grosse punctato, stria integra, margine 

 laterali angustissimo, elevato ; elytris striis distinctis puncti- 

 formibus, fasciis transversis medio albis ; abdomine subtilissime 

 punctato. L. 4 lin. 



Broader than N. nitidus^ C. Waterh., with acute angles to 

 the thorax, which gradually widens to the base, where it is as 

 wide as the elytra. The fascia is irregular, and, during life, 

 white. Suture and antenna? black, and the apex of the elytra 

 truncate. 



Hob. Yamato. 



Scaphidium Reitteri, n. sp. 



S. ovatum, piceum, nitidissimura ; fronte, ore, thorace ad marginem 

 et in medio late, elytrorum fasciis duabus, pygidio propygidio- 

 que rufescentibus ; antennis basi piceis, articulo ultimo rufo. 



Half the stature of S. japonicum, Reitter, with elytra more 

 truncate, and the colour wholly different. I have much
