the middle, but Is of an elongate diamond-shape. , The elyti-al 

 stride also are very deeply punctate and the interstices clearly 

 convex. On the under surface I have not observed any very 

 important characters ; but the checks under the eyes are con- 

 vex and give a striking appearance as compared with R. exara- 

 tus. When the male is discovered it will probably be found 

 to present remarkable sexual differences. 



I have named this species after Herr Hans Leder (to whose 

 researches on the eastern confines of Southern Europe scientists 

 are indebted for many rare species) with the latent hope that 

 he may discover the male. 



Clinidium, Kirby, 1835. 



Eyes narrow, somewhat elliptical, and obscurely granulate. 

 Theregion of the scutellum is profoundly depressed, and the 

 species are apterous. 



Clinidium veneficum, sp. n. 



Elongatum, brunneum, nitidum. C. Guiklinr/i proxime affiuis at aii- 



gustior. 

 L. 7-7^ miU. 



Elongate, brown, shining; head with cephalic lobes oblong, 

 rather widely separated, but sometimes approaching each 

 other between the eyes, frontal elevation somewhat cordate ; 

 thorax with two parallel lateral sulci and a median sulcus, 

 which is narrowest in the middle and deepest in front and 

 behind ; the intermediate sulci are short and broadest at the 

 base, which gives an appearance of obliqueness. The elytral 

 stria3 are narrow, the third bemg the widest and deepest, and 

 in the female this stria is widened out behind the legs. The 

 male has an obsolete tooth on the fore femur and a conspicuous 

 incurved spine at the bases of the middle and hind tibiie. 

 The female has the hind tibi^ a little swollen at their bases 

 and the last segment of the abdomen is largely excavated, 

 with two large rather acute tubercles on each side. In the 

 male the tubercles are small and the abdomen is not exca- 

 vated, but merely impressed. 



This species is more elongate than C. Guildingi, Kirby, and 

 in the male the middle and hind tibiai are more slender and 

 the apical spines long.er. The singular abdominal characters 

 are worthy of notice. 



I found it at Hakone in old beeches, and under like con- 

 ditions in several places in the province of Higo, in Kiushiu.
