and connects with the suture, tlie intermediate costa ceasing 

 abrupt!}' a little behind the commencement of the declivity. 

 Oyayama, near Kumamoto ; two examples. 



Teeedol^mus, nov. gen. 



Corpus subcylindricum. Antennse lO-articulatfe, articulo basali libero, 

 clava magna votundata uniarticulata. Tibiae extus ad apicem vix angulatae, 

 calcaribus minutis; tarsi parum elongati, articulo basali tibiae apicem baud 

 superante. Coxse anteriores contiguse, intermedin et posteriores acumi- 

 natae ; abdomen segmento primo ventrali sequente conspicue longiore. 



This genus is allied to Teredus and to Oxylcemus ; from the 

 former it differs by the structure of the antennae, and the shorter 

 form, the prosternum in front of the coxae being but little elon- 

 gate : in the structure of tlie antennae it agrees tolerably witb 

 Oxylcemus, from which it differs in a number of characters, such 

 as the simple tibiae, the uncompressed prosternum, and tbe 

 obsolete antennal furrows. One of the species has been already 

 described by Mr. Lewis as a Teredus ; but he remarked that the 

 species would probably require generic separation on account of 

 the antennal structure. 



TEKEDOLiEMiJS POLiTUS. (Plate III. fig. 7.) 

 Teredus politus, Lewis, Ann. Nat. Hist. 1879, p. 462. 

 Konose in Higo ; seven specimens. 



Teeedol^mtjs QTJTTATirs, n. sp. 



Cylindricus, parura elongatus, nitidus, niger ; elytris ad apicem, antennis 

 pedibusque rufis ; subtiliter punctatus. Long. 2|-3 millim. 



Thorax about as long as broad, sparingly and finely punctate. 

 Elytra with rows of fine punctures, becoming obsolete at the 

 extremity ; interstices impuuctate, each impressed near the suture 

 just before the apex, and the apical portion furnished with a very 

 few elongate extremely fine setae. 



The individuals of this species are smaller than those of 

 T. politus ; and are readily distinguished by the large red mark 

 and tbe finer punctuation. The species probably preys on some 

 member of the Tomicidae, to some of which it is similar in form ; 

 and it is curious that the apex of the body is also like many 

 Xylelori in form. 



A. good series of this species was secured at Kashiwagi in the 

 month of June, and it was also met with during the previous 

 month at Tuyama.
