postice sensirn contractis, fortiter marginatis; elytris apicem versus 

 vix angustatis, distincte sed haud fortiter punctato-striatis, apicibus 

 conjunetim truncatis: pedibus rufo-piceis vel rufis, genibus et fe- 

 moribus obscurioribus; corpore subtus piceo ad partem rufescenti; 

 lineis coxalibus sat longis, parallelis, ad apices sensim diver gentibus. 



A subparallel rather shiny and rather robust species with the front 

 parts and scutellum red and the elytra obscurely greenish or bluish 

 aeneous; head with the eyes prominent, finely granulated, antennae 

 reddish at base with a black five-jointed club, the first joint being 

 small; prothorax broadly subcordiform, about as long as broad, but 

 somewhat variable with strong margins with the sides rounded in front, 

 broadest about middle and contracted before base, almost smooth or 

 very finely punetured, basal impression and Striae deep; elytra only 

 slightly contracted behind, strongly margined, with the humeral 

 inipressions well marked, and with regulär but not strong rows of 

 punctures, apices jointly and simply truncate or almost rounded; 

 legs pitchy or pitchy red in part darker ; underside pitchy, partly rufescent ; 

 coxal lines parallel, rather long, not far apart, divergent at apex. 



Length 8 — 9V 2 mm. 



About a dozen examples: Suisharyo, Oktober 1911; Taihorin 

 October 1909; also taken in 1910 and 1911: Kankau (Koshun) May 

 1912, Chikutoki May 1911. 



This species varies somewhat in size, colour of underside and 

 legs, shape of prothorax and punctuation but intermediate examples 

 occur and I think all must be referred to one species. 



Anadastus angustior sp. n. 



Angustus, parallelus, capite prothoraceque rufis vel piceis, elytris 

 plus minusve obscure coeruleo — aenescentibus : capite triangulari, 

 oculis modice granulatis, antennis clava 5-articulata, piceis, vel ad 

 basim rufescentibus! prothorace subquadrato, latitudine paullo longiori, 

 lateribus fere parallelis, marginatis; elytris vix postice contractis 

 sat regulariter punctato — striatis, distincte marginalis, apicibus con- 

 junetim truncatis; corpore subtus piceo; lineis coxalibus sat longis, 

 parallelis, approximatis ; pedibus piceis. 



A small, very narrow, elegant parallel species with the front 

 parts red, or entirely dark pitchy reddish : elytra variable, sometimes 

 brightly, sometimes obscurely bluish metallic; head triangulär, rather 

 distinctly punetured, eyes prominent moderately granulate, antennae 

 rufescent at base or entirely pitchy with a 5- jointed club, the last three 

 joints being the broadest and the first joint (7 of the antennae) being 

 only slightly thickened; prothorax subquadrate. a little longer than 

 broad, with the sides almost straight and parallel, slightly narrowed 

 before base, distinctly margined, anterior angles well marked, very 

 finely punetured on disc; elytra long, parallel, scarcely narrowed 

 towards apex, with more or less regulär rows of fine punctures and 

 finely rugose, apices jointly truncate; legs and underside pitchv- 

 black; coxal lines rather long, parallel and approximate.
