266 Mr. H. W. Bates' supplement to the 



Pogonus Japonicus, Putzeys. 



Putzeys, Ann. Soc. Ent. Belg., 1875, xviii., p. 8. 



S. Nipon ; one example. 



Not met with by Mr. Lewis. 



Putzeys records a P.flavipes, Motsch., from Japan im- 

 mediately after the above ; the species is no doubt the 

 well-known Patrobus flavipes, and not a Pogonus, as the 

 author's mode of entering it on the list would lead one 

 to infer. 



Trechus discus, F. 



Tokio ; Niigata ; Hakodate. 



Three examples not distinguishable from European 

 specimens. Two of them are rather larger, viz., 2£ — 

 3£ lin. The size given by Schaum in the Ins. Deutschl. 

 is 2^ lin. 



Trechus oreas. 



T. rubenti proxime affinis sed differt capite multo 

 angustiori, mandibulis valde elongatis, oculis parvis, etc. 

 Gracile ovatus sat convexus, castaneo-rufus glaber, palpis 

 antennis pedibusque pallidioribus ; capite angusto, elon- 

 gato, post oculos parvos gradatim angustato ; thorace 

 quam in T. rubenti longiori, subcordato ante basin pro- 

 funde sinuato, angulis posticis acutis exstantibus ; elytris 

 elongato-ovatis, humeris nullo modo angulatis, striis 

 omnibus sat profundis 3 — 4 et 6 — 7 apice abbreviatis, in- 

 terstitiis convexis. Long. 5f mm. 



Iwaki-san. Under stones by a streamlet near the 

 summit. 



At first sight appears closely allied to T. rubens, but in 

 outline more nearly resembling T. procerus or T. navari- 

 cus ; head and eyes similar in shape to those of the 

 latter, but mandibles still more elongated, 



Trechus punctatostriatus, Putzeys. 



Putzeys, Deutsche Ent. Zeitscbr. 1877, p. 85. 



Japan (Hiller). 



Mr. Lewis does not appear to have met with this 

 species, which differs from T. ephippiatus in the striae 

 being all entire.
