nero Species o/Histevidse. 25 



widened triangularly at the base and the strias gradually meet 

 anteriorly ; the mesosternum is margined anteriorly, with a 

 transverse crenulate stria at the base ; the anterior tibi» 

 4-dentate. 



This species is not much like any other species I know. 

 H. varians, Sch., a common Japanese species, has no meso- 

 sternal transverse stria. 



Hah. Ishikari River, Yezo. I obtained this species from 

 a Japanese I sent to collect insects in Central Yezo in 1882. 



Hypocaccus rujipes, Payk. 



I found an example of this species at Enosliima, near Yoko- 

 hama, in May 1880. This is the first record of its occurrence 

 in Japan. 



Hypocaccus ruhicillioi, sp. n. 



Ovalis, niger, nitidus, elytris partim rufis ; capita thoraceqne im- 

 punctatis ; mesosterno margine late interrupto ; tibiis anticis 

 6-dentatis. 



L. 21 mill. 



Oval, black, shining, the elytra red, with the scutellar disk 

 and posterior margins obscurely black ; the head and thorax 

 smooth and impunctate, without strise or sulci, the first has a 

 well-marked carina, the second a fine marginal stria which 

 continues in front close along the edge; the elytra finely, 

 not closely, punctulate apically — striae, external subhumeral 

 wanting, internal short and apical, with a fine basal oblique 

 appendage, dorsal 1-3 short, not reaching the middle, very 

 fine, oblique, and punctate or punctiform, 4 very short and 

 indicated on the disk by only a few small points, 5 absent, 

 sutural apical and anteriorly punctiform ; the pygidia are very 

 evenly and very finely, not densely, punctured ; the pro- 

 sternum, keel narrow, but widening out a little at the base, 

 striae cariniform, parallel, joining in front and looped together 

 posteriorly at the widening out of the keel ; the mesosternum, 

 marginal stria somewhat deep and confined to the anterior 

 angles, it does not join the metasternal stria ; the metasternal 

 stria is oblique and longer than the mesosternal stria ; the 

 first abdominal segment is clearly punctured, but there are 

 very few points in the central area ; the anterior tibiae are 

 6-dentate and the posterior tarsi are very robust. 



This species is remarkable for its coloration, and its head and 

 thorax are impunctate, like those of Pachylopus dimidtatus, 

 111. 



Hab. Nguela, Usambara. In the collection of the Royal 

 Museum at Brussels and my own.
