new Japanese Cohoptera. 335 



Chrysodema oshimana, Nonfried, 1895, = 0. Lewisii } 

 Saimd. 1873. 



Nonfried's description appears in Berl. ent. Zeitschr. xl. 

 p. 297 (1895). In the Journ. Linn. Soc., Zool. xxiv. p. 328 

 (1892) I recorded this species from Oshima. Nonfried also 

 (I. c.) redescribes Cetonia Pryeri, Jan, as C. oshimana. 



Corcebus Oberthiiri, sp. n. 



Capite aureo-viridi ; thorace disco cyaneo, lateribus viridissimis ; 

 elytris albo-fasciatis, apiee utrinque bispinosis, basi et apice 

 aureo-viridibus, in medio aureo-cupreis ; subtus antennis pedibus- 

 que obscure geneis et griseo-pubescentibus. 



L. 10| mill. 



The head rich golden green, frontal channel deep, not 

 angulate behind, punctate, punctures deep and elongate, 

 especially lengthening (almost furrow-like) before the neck, 

 where they are generally transverse ; the thorax coarsely and 

 transversely sculptured, feebly arched in outline from the 

 anterior angle to the base, edges crenulate, sides somewhat 

 explanate at and before the bases, rich blue on the disk and 

 base, golden green laterally and blue-green behind the neck ; 

 the scutellum, anterior portion transverse, with sharply defined 

 truncate sides, and an acuminate triangular area behind, 

 median space rugosely punctate ; the elytra, sculpture 

 distinctly transverse and somewhat coarse, golden green at 

 the base, narrowly only near the suture, but at the humeral 

 angle the green colour stretches out broadly along the sides 

 almost to the middle of the wing-case, at the apex about one 

 fourth of the elytral length is golden green, the central area 

 coppery red, and this colour extends along the suture nearly 

 to the base; across the coppery dorsum is a rather wide white 

 pubescent fascia, with a white patch in front of it near the 

 suture, the apex is 4-spinose, two on each elytron, the outline 

 of the elytral edge between the spines is narrow and semi- 

 circular (in C. niponicus this outline is wide and nearly 

 straight) ; the ventral segments above are of a deep rich blue, 

 beneath the whole body is obscurely ameous and pubescent, 

 and the antennae and legs concolorous. 



This species is the size of G. niponicus, Lew., and should 

 be placed next to it in the Catalogue. 



Uab. Oshima. 



It gives me much pleasure to name this species after 

 Mons. Rene Oberthiir, from whom I received it.
