l.'irfjer, tlio elytra longer, the thorax wider anteriorly, tlie lieail 

 anil neck lii^litly and obscurely punctured ; the frontal suture 

 (w(dl defined in the other species of this series) can otdy be 

 feebly traced in certain lights, and the metasternuni is free of 

 pilosity in the male. 



The district in which it was found is the same as that in 

 which S. V(thfipes is common. 



Iluh. Yuyama. One male example. 



Setenis vaJgipes, Mars. 

 Nydohates vaUjipes, Mars. Ami, Fr. 1876, p. 117. 



In the male of this species the median area of the meta- 

 sternum is densely pilose. Marseul does not mention this, 

 but he notices that N. villosipes, Mars., from Mantchuria, is 

 similarly clothed. If it should prove that he attached this 

 last character to the wrong species (he corrected his proof 

 more than two years after parting with his manuscript), my 

 S. insoninis may be the same as his Mantchurian species. 



J Jab. Nagasaki, Konose, and Yuyama. Common in old 

 firs {Piyiiis 7nassoinana). 



Setenis striatipennis, sp. n. 



Elongatus, niger, nitidus ; thorace canaliculate et bifoveolato ; 



elvtris valdc punctato-striatis. 

 L. 20 mill. 



Elongate, black, shining ; the head anteriorly rather 

 densely punctured, more sparingly between the eyes ; the 

 thorax with a narrow and rather shallow median channel and 

 two foveae on each side of it before the base, punctate like 

 the head between the eyes, lateral margin narrowly raised, 

 liind angles rectangular; the elytra strongly punctate-striate, 

 interstices very finely punctulate. The sexual differences are 

 slight ; in the male the anterior tibiie are longer and rather 

 more incurved ; the metasternuni is not pilose. 



Agrees somewhat with Nydohates semisulcata, Fairm. 



Ilab. Yuyama and Konose. Common in the Kuro-matzu 

 ( Pin us massoman a) . 



Setenis noctivigilus, sp. n. 



EloDgatus, niger, subnitidus ; antennis pedibusquc rufo-piceis ; 



capite thoraceque opacis ; elytris parum valde puuctato-striatis. 

 L. 15 mill. 



Elongate, black ; head and thorax somewhat opaque, elytra 

 somewhat shining; autcnntc, mouth-organs, frontal anterior
