perparum confluentibus, fasciis duabus fulvis, sed fasciis fuscis 

 plerurnque vix perspicuis. Long. 12-16 millim. 



Oyayama and Niohozan. 



Presents a different appearance from tbe European JR. inqui- 

 sitor, owing to the tawny spots of the elytra being nearly always 

 separate, exposing more of the shining brassy-black ground- 

 colour. The spots in most examples are condensed into two 

 widely separated fasciae. A fascia of the dark ground-colour 

 sometimes shows behind tbe second tawny belt. Examples, 

 bowever, occur which do not diff"er from European specimens. 



Xenophtbama, nov. gen. 

 Gen. RJiamnusio (Latr.) approximans. Corpus oblongum. 

 Caput quadratum, ante oculos parum elongatum (sed mandibulis 

 elongatis), genis post oculos elongatis rectis vel postice subdila- 

 tatis, ab angulis oblique ad coUum angustatis ; coUo parum con- 

 stricto, vertice post antennas depresso,bituberoso, tuberibus (sicut 

 tuberibus antenniferis) a linea dorsali profunda separatis ; oculi 

 subgrosse granulati sat jjrof'unde siuuati ; tubera antennifera 

 valida, elevata. Antennae ( $ ) sat graciles fere corporis apicem 

 attingentes, prope oculorum marginem anticam insertae ; arti- 

 culis 3-4 coujunctis quam 5""^ vix longioribus, 5-11 filiformi- 

 bus, aequalibus. Thorax amorphus : apud apicem a.ugustus 

 et sulcato-constrictus, delude subito dilatatus et usque basin 

 figuram cuboideam efiiciens, dorso utrinque in tuber magnum, 

 apice concavum, sicut inflatus ; lateribus utrinque ante medium 

 prominens ; basi sulcato-depressus angulis posticis fere rectis. 

 Elytra convexa sat late elougato-oblonga, apice late rotundata. 

 Prosternum inter coxas angustissimum baud perspicuum, coxis 

 Talde exsertis. Pedes sat graciles, posticis relative baud longio- 

 ribus, tarsis posticis brevibus, articulo primo lineari, quam 2-3 

 conjuncti longiori. 



Although totally" diff"erent in facies, due to the broad oblong 

 elytra, opaque surface, longer antennae, &c., this genus is un- 

 doubtedly allied to Rhamnusium.
