452 Dr. D. Sharp on 



black patch about the scutellum ; sparingly punctate. Hind 

 body with first four segments red, the two terminal clear 

 black. Mesosternuin yellow ; metasternum blackish. 



A distinct species to be placed near T. ohtusus. 



A single male was found at the Shimonosuwa Lake, 31st 

 July, 1881. 



Tachyporus celatus. 

 Tachyporus celatus, Sharp, Trans. Ent. Soc. Lond. 1874, p. 17. 



This is apparently one of the commoner species of Staphy- 

 linid^ in Japan, and though I have not seen very many 

 specimens, is, I think, very variable in colour.

Tachyporus suavis, n. sp. 



Niger, nitidus ; antennis, palpis, prothoraeis lateribus pedibusque 

 testaceis ; elytrorum apice plus minusve evidenter pallido ; anten- 

 nis extrorsum evidenter crassioribus ; prothorace elytris con- 

 spicue latiore. 



Long. 5 millim. 



Var. Antennis extrorsum fuscescentibus. 



Antennae rather stout, tenth joint about as long as broad. 

 Prothorax curved at the sides and much narrowed in front, 

 black, but yellow at the sides, the yellow colour being 

 broadest near the hind angles. Elytra considerably longer 

 than the thorax. Hind body with a sparing but distinctly 

 impressed punctuation. 



This is readily distinguished from the darker specimens of 

 2\ celatus by its thicker antennss, as well as by the more 

 elegant coloration ; it is remarkable from the fact that the 

 punctuation of the hind body is a true punctuation, consisting 

 evidently of fine impressed punctures ; this is best seen near 

 the base of each segment, the punctures becoming quite 

 obsolete on the hinder part of each plate. 



Single individuals have been four times met with, at Yu- 

 yama in May, at Fukushima at the end of July, at Chiu- 

 zenji and at Nikko in August, 1881. Of the variety with 

 darker antennae single individuals were twice found, viz. at 

 Shimonosuwa on the 31st July and at Nikko on the 18th 

 August. 



Tachyporus oculatus, n. sp. 

 Fusco-niger, abdomine nigro ; antennis fuscis basi dilutiore, palpis
