around the scutellum. The punctuation of the elytra is rather 

 distant, strongly impressed, and arranged in lines. Varieties 

 occur in which the metasternum and the middle of the basal 

 ventral segments are blackish, others in which the sides of 

 the basal ventral segments only are blackish. 



Oberea hebescens, n. sp. 



0. japonicce simillima, differt solum thoracis medio magis convexo, 

 elytris apice oblique truncatis, haud spinosis. Longit. 7-8

Among Mr. Lewis's numerous series of O.japonica are three 

 examples ( <$ ? ) of a form precisely similar in colours, except 

 that the lateral dark stripe of the elytra extends further over 

 the humeral callus ; but the apex is simply obliquely truncated, 

 without spine either at the sutural or exterior angle. The 

 thorax also is decidedly more convex on the disk, with a distinct 

 transverse sulcus near the anterior and posterior margins. 

 The punctuation is the same, particularly the regular strong 

 lineate punctures of the elytra, confused and faint only near 

 the apex. The terminal abdominal segment is black, the rest 

 of the under surface, the legs, the thorax, and the base of 

 the elytra (except the humeral callus) testaceous yellow or 

 reddish. 



I think it very possible that it is only a variety or aberration 

 of O.japonica. 



Oberea mixta, n. sp. 



0. japonicce proxime affinis ; differt solum punctis elytrorum con-

Simabara, Osaka ; four examples. 



Deceptively similar to 0. japonica ; rather less elongated, 

 and the punctuation of the elytra not arranged in lines. The 

 head and thorax do not differ in form or colour ; but the an- 

 tennas are decidedly shorter in both sexes. The testaceous 

 red colour of the base forms only a square patch over and 

 around the scutellum and a narrow streak down the extreme 

 margin below the humerus ; the truncation of the elytra is less 

 oblique, and both angles are produced and spiniform, the 

 exterior one much the longer ; the base of the apical ventral 

 segment is yellow, the rest black.
