458 Dr. D. Sharp on 



segments and only moderately close on the penultimate. The 

 legs, including the front coxse, are yellow ; the breast is black. 

 This is about the size of our European B. trinotatus, but has 

 a mucli longer head and is differently coloured. 

 Nikko and Chiuzenji ; five examples. 



Bolitobius cinctiventns, n. sp. 



Niger, antennarum basi, palpis, pedibus elytrisque testaeeis, his ad 

 ang'ulos posteriores nigro-mactilatis ; abdomine fortiter punctato, 

 segmentorum margiuibus posterioribus testaceo-cingulatis. 



Long. 7^ millim. 



Antennge rather short ; fifth to tenth joints subequal, no one 

 of them longer than broad ; terminal joint short, pale at the 

 tip. Head black, short. Thorax black, scarcely so long as 

 broad. Elytra yellow, with a large diagonal black mark at 

 each outer hind angle, and with a small dark mark round the 

 scutellum extending backwards along the suture ; the sutural 

 and dorsal series consist each of about eight punctures. Hind 

 body dark, each segment with the hind margin remarkably 

 definitely testaceous, the basal segments very sparingly punc- 

 tate, those behind rather coarsely though not densely so. 



This may be placed near 5. trmotatus, but is not very close 

 to any species I know. 



Oyama, Miyanoshita ; only three ill-preserved examples 

 were obtained. 



Bolitobius brevicepsj n. sp. 



Niger, antennarum basi, palpis, pedibus elytrisque testaeeis, thorace 

 ad latera flavescente ; elytris ad angulos posteriores nigris, serie- 

 bus dorsalibus et suturalibus circiter 9-punctatis. 



Long. 6 millim, 



Antennai with the four basal joints pale, tenth joint about 

 as long as broad, terminal joint elongate, about twice as long 

 as the tenth. Head black, very short, eyes but little distant 

 from the thorax. Thorax not so long as broad, black, with 

 the sides yellow, this colour rather broader behind. Elytra 

 yellow, not marked with black round the scutellum, but with 

 each outer angle diagonally black, the dark colour extending 

 quite to the hind margin, scarcely reaching the suture, but 

 at the outer margin extending far forwards. Hind body 

 black, with the penultimate segment broadly ringed with 

 yellow, rather finely punctate. 



Nikko, June 1880 ; two ill-preserved examples.
