Phytophagous Coleoptera of Japan. 187 



A. angulicollis. Scutellum narrov/ly triangular, its apex 

 obtuse. Elytra yellowisli-wliite, distinctly punctured ; each 

 elytron with two large confluent patches, the first extending 

 from the base to the middle of the disk, the second from 

 the middle nearly to the apex, black. 



Genus LuPERODES, Motsch. 

 Etud. Ent. vii. 102. 



Luperodes quadriguttatus, IMotsch. 



Schrenck, Eeis. in Amur-land, ii. p. 233, Tab. xi. fig. 20. 



Hah. — Nagasaki ; also Eastern Siberia and Dauria. 



Luperodes discrepens, Baly. 



^ Iphidea discrepens, Baly, Ent. Month. Mag. ii. 127. 



Var. A. Abdomine flavo-albo. 

 Hab. — Nagasaki. 



I find that the length of the second joint of the hinder 

 tarsus differs greatly in different species of Luperodes ; in 

 consequence my genus Iphidea, founded on the relative 

 length of the joints, must fall. The specimens brought 

 over by Mr. Lewis are paler in colour, and have the 

 abdomen yellowish-white. My type of Iph, discrepens is 

 at the present time in the hands of ^M. Chapuis for ex- 

 amination, so that I am unable to compare them with it, 

 but I think there is no doubt but that they belong to the 

 same species. 



Luperodes pallidulus. 



Ovatus, convexus, pallide flavus, nitidus, antennis (basi 

 excepta) fuscis, oculis nigris ; thorace elytrisque distincte 

 punctatis. 



Long. 2—21 lin. 



Hab. — Nagasaki. 



AntennfE slender, equal to the body in length, four 

 lower joints pale flavous, the rest fuscous ; encarpa3 trans- 

 verse, separated (except at the extreme apex) by the 

 carina ; eyes large and prominent, shining black. Thorax 

 twice as broad as long, sides straight and nearly parallel, 

 obliquely deflexed fi'om base to apex ; anterior angles 

 thickened, very obtuse, hinder angles slightly produced.
