Species of Coleoptera from Japan. 463 



Cetonia brevitarsis, n. sp. 



C. breviter ovata, subnitida, cuprea, albo-variegata : C. submarmorea; 

 affinis. L. 9-10 lin. 



The chief differences between this species and C. submar- 

 morea are : — the clypeus is raised in front, but not notched ; 

 the whole outline is more quadrate; the punctation below the 

 humeral angle more strigose, and the tarsi are both shorter 

 and thicker. These points are very perceptible in a large 

 series I have from South Japan, where it is very common. 

 In colour it varies from blackish brass to a reddish coppery 

 tint. 



Sab. Nagasaki. 



Cetonia insperata, n. sp. 



C. 2 oblonga, nitida, purpureo-serea ; elytrorum lineis transversi3 

 albis angustissimis, disco obsolete punctato ; abdomine convexo, 

 laevi. L. 9^ lin. 



Not closely allied to any species I know. The polished sur- 

 face separates it from any Japanese species ; the puncta- 

 tion of the elytra is comparatively obsolete ; and the white 

 markings are very narrow. The head is fairly punctured, 

 and the edge of the clypeus slightly raised both in front and 

 at the sides. The propygidium and pygidium have the stri- 

 gose punctation of the preceding, but rather less deeply 

 impressed. The outline of the insect viewed sideways between 

 the lobe of the mesosternum and the apex of the elytra is 

 concave. 



Hab. Yezo. 



Ichthyurus niponicus, n. sp. 



/. fuscus ; fronte depressa, flavo-testacea, capitis basi late nigra ; 

 tborace disco nigro, margine antice late, basi anguste flavo ; 

 elytris nigro-fuscis, marginibus externis flavis ; antennis testaceis, 

 apicem versus fuscescentibus ; abdominis margine late flavo. L. 

 2f lin. 



This species is the smallest yet observed in the genus, and 

 possesses the usual colours. The large middle thigh is dusky 

 at the joint ; and the posterior leg has the tibia and half the 

 thigh darkish ; but the anterior leg is wholly pale. 



Hab. Hiogo, foot of Maiyasan. 



Ischalia patagiata, n. sp. 



/. oblonga, depressa, nigra, parce albo-hirta ; antennis pedibusque 

 obRCuro-nigris ; elytris externe late luteo-marginatis. L. 2^-3 

 lin.
