Slaphylinid<2 of Japan. 53 



broad as the thorax, coarsely but not densely punctured, 

 with an impunctate space along the middle ; in front in 

 the middle, between the frontal channels, is a short obscure 

 channel, and the space here is finely strigose, so as to be 

 less shining than the other parts. Thorax nan-ower than 

 the elytra, shining brassy black, with a dorsal series of 

 about eight punctures, and with an irregular curved lateral 

 series of about the same number, and with some additional 

 punctures near the front. Elytra quite as long as, or even 

 a little longer than, the thorax, of a yellow colour, but 

 more or less suffused with a dark colour, so as to be some- 

 times almost entirely pitchy, generally with the suture and 

 extremity broadly pale yellow ; they are coarsely and 

 moderately closely punctured. Hind body tinged with 

 brassy, sparingly punctured ; legs reddish. Under side of 

 head rather coarsely, sparingly and regularly punctured, 

 and finely strigulose so as to be made somewhat dull. 

 Prosternum and margins of thorax dark red. 

 Abundant at Nagasaki. 



99. Xantholinus mixtus, n. sp. Xigro-jeneus, nitidus, 

 elytris feneo-piceis, fortiter punctatis; antennis obscure 

 rufis, pedibus rufis ; capite punctato, punctis e majoribus 

 et minoribus compositis, thorace serie dorsali circiter 9, 

 lateraH circiter 7, punctatis. Long. 4 lin. 



Closely allied to A', sujfusus, but rather narrower, "with 

 the elytra more unicolorous, but easily distinguished by 

 the sculpture of the head. The lai-ge punctures of the 

 head are much smaller and are less numerous than in 

 suffusus, and mixed with them are a number of much 

 finer pxinctures; these fine punctures however are Avanting 

 at the hinder part, and they appear to vary in their number, 

 but are always most numerous about the frontal furrows : 

 the head on the under side has some scattered large punc- 

 tures, as well as a large number of small punctures similar 

 to those of the ujiper surface. 



Abundant at Nagasaki. 



In certain specimens (probably males) of this and of 

 A', suffusus, the middle lobe of the 8th segment of the hind 

 body is depressed along the middle and has each of its 

 hinder angles a little produced.
