Ilah. Fukushima, Nikko, auJ Osaka. Fairly common in 

 flowers of Viburnum. 



Melanoxanthus zebra, Wicdm.

Candbze records this species from Japan (Mon. ii. p. 516). 

 It is a common Javan species, and I think it reqnires con- 

 firmation before admitting it to the Japanese Catalog-ue. 

 Schoiifi'ldt apparently is also of this opinion, as he lias 

 refused to give it a place in his Catalogue. 



As I think it is undesirable to place insects such as the 

 three following in the same genus as the small Grj^ptohijpnij 

 I have utilized the genus proposed by Eschscholtz for Cn/pto- 

 hypnus hyperboreus, Dej. {planatus, Eschs.), to receive them. 

 In two of the Jaj)anese species the expanded basal joint of 

 the antennfe is very remarkable, in the third (//. fluviatilis) 

 the basal joint agrees more with C. hyperboreus. 



IlypoUthus saxatilis, sp. n. 



Depressus, nigcr, subnitidus, nigro-puboscens ; antcnnis articulo 

 prirao valde expanse ; thorace in medio carinato ; pedibus infus- 

 catis vel ferrugineis. 



L. 7i-10 miU. 



Depressed, black, with rather short black pubescence ; the 

 head, frontal carina well marked behind the antennai, punc- 

 tured not closely in the middle, but thickly and roughly 

 near the eyes, forehead impressed ; the thorax densely and 

 rugosely punctate, with a longitudinal smooth line in the 

 middle, hind angles slightly turned outwards, short but acute ; 

 the scutellum very feebly punctulate ; the elytra striate, 

 striae rather deep, interstices flat, rather closely punctured, 

 little rugose ; the antenna?, basal joint flattened out and 

 expanded, nearly semicircular on the anterior edge, posterior 

 edge nearly straight, second, third, and fourth joints equal in 

 length, reddish or pitchy brown ; the legs dusky. 



Kesembles somewhat //. hyperboreus, Gryll-j but is more 

 depressed, and the basal joint of the antennae flatter and more 

 expanded. I believe C. Sanborm, Horn, resembles II. saxa- 

 tilis. 



Hub. Kiga, Plakone, Chiuzenji.
