1885.] COLEOPTERA FROM JAPAN. 209 



This species evidently represents the subsection of the European 

 genus Oreina in Japan, and is I think closely allied to G. speciosa, 

 Fabr., or one of its numerous varieties, but is, I have no doubt, 

 distinct from that or any other species of this most difficult group. 

 According to Mr. Baly, C. speciosa has the deep thoracic lateral 

 groove broadly interrupted at its middle ; in the present insect this 

 groove is very deep and extends upwards to more than two thirds 

 the length of the thorax, being interrupted only close to the anterior 

 margin. In this as well as in coloration all the 30 specimens 

 before me agree ; but the punctuation, as already remarked, of the 

 upper surface is extremely variable, but much more strongly and 

 rugose than in any of the European species with whicli I am 

 acquainted. 



Genus Phytodecta. 



Phytodecta robusta, sp. nov. 



Broadly ovate, subqnadrate, fulvous ; thorax sparingly punctured 

 at the sides only ; scutellum black ; elytra strongly punelatc- 

 striate, the interstices finely punctured, fulvous ; two elongate 

 spots at the base and two behind the middle, sometimes connected, 

 blfick. 



Length 3 lines. 



Head finely and distantly punctured. Antennae very short, not 

 extending to the base of the thorax, entirely fulvous, the last five 

 joints transversely dilated. Thorax transversely convex, the sides 

 nearly straight, the basal margin broadly rounded at the middle ; 

 disk very distantly and finely punctured, the sides impressed with a 

 few strong and more closely jilaced punctures. Scutellum black. 

 Elytra convex, not broader at the base than the thorax, each elytron with 

 ten rows of deep punctures, visible to the apex, the interstices finely 

 but closely punctured ; each elytron with an elongate subtriangular 

 spot at the shoulder, another more rounded one at the base near the 

 scutellum, a third, generally elongate and of triangular shape, at the 

 sides below the middle and connected with a fourth shorter spot 

 near the suture, this latter spot sometimes isolated ; another very 

 small sutural spot is placed at the apical angle. Underside and legs 

 entirely fulvous, the abdominal segments strongly punctured. Tibite 

 short, and broadly dilated at the outer side. 



Miyanoshita, Hingo (also coll. Jacoby). 



This species is of a much more convex and robust shape than 

 most of our European forms, from which and others it may be further 

 distinguished by the nearly impunctate or sparingly punctured 

 thorax, the entirely fulvous and short anteniise, and the different 

 shape of the elytral spots, the outer ones of which are very elongate, 

 the inner ones of more rounded shape. The tibiae are also very 

 short and more dilated than usual, and the broad base of the elytra 

 gives the insect a general square-shaped appearance. A single 

 specimen is contained in my own, two cithers in the collection of Mr. 

 Lewis.
