Phytophagous Coleoptera of Japan. 175 



a smooth impimctate oblique space, wliich extends on 

 either side from the inner edge of the antenna, and meets 

 its felloAv at the apex of the clypeus. Thorax more than 

 twice as broad as long; sides converging and slightly 

 rounded from the base upwards, more quickly rounded at 

 the apex ; anterior angles obtuse ; above transversely con- 

 vex, strongly but not very closely punctured ; the punc- 

 tures rather less croAvded on the disk. Elytra broader 

 than the thorax, convex ; regularly punctate-striate, the 

 punctures smaller and rather less deeply impressed than 

 those on the thorax ; strife faintly sulcate ; interspaces 

 plane, nearly impimctate, a few indistinct punctures being- 

 visible under a lens. Anterior coxa) slightly elevated. 



^ Phcedon ijicertum. 



Ovatum, convexum, nitidum, subtus nignira, supra 

 nigro-feneum, antennis uigris ; capite fortiter punctato ; 

 thorace la^vi, tenuiter punctato, ])unctis disco remote- 

 lateribus minus remote-dispositis ; elytris regulariter punc- 

 tato-striatis, interspatiis planis.

Ilab. — Nagasaki; a single specimen. 



Head strongly punctured ; clypeus shorter than in Ph. 

 BrossiccB, pentangular ; two smooth spaces, not contiguous 

 at the apex, separate it from the upper face. Thorax more 

 than tAvice as broad as long ; sides obliquely couA-erging 

 and rounded fi-om base to apex, more quickly rounded near 

 the anterior angles, the latter subacute ; upper surface 

 smooth, finely but distinctly punctured, the punctures dis- 

 tant on the disk, rather larger and more closely placed on 

 the sides. Scutellum semiovate, impressed on either side 

 at the base Avitli a small fovea. Elytra similar in form 

 and punctation to the last species. 



Closely allied to Ph. Brassicoe. The subacute angles of 

 the thorax, together Avith the more finely punctured disk 

 of the latter, at once separate it from that insect.
