Wi W. Fowler: 



Two specimens from Taihorin 1911, two from Suisharyo, Oct. 1911 

 and two from Kankau, April and August 1912; one of the specimens 

 from Taihorin is about half the size of the others and has the elytra 

 more strongly punctured, but they appear to belong to the sarae 

 species: it is a very distinct little insect, by means of its shape and the 

 eonvexity and evenly rounded sides of the prothorax. 



In the collection there are two other small insects, apparently 

 belonging to two species of Perilanguria, from Kankau: I do not 

 however care to describe them without further material; theyclosely 

 resemble one another, but differ in the formation of the antennal 

 club and other particulars. 



Anadastus robustior sp. n. 



Sat latus, robustus, parallelus, capite prothoraceque rufescentibus, 

 elytris obscure viridiscenti aeneis, corpore subtus cum pedibus piceis; 

 capite levissime punctato, antennis nigris, ad basim rufis, clava 5-arti- 

 cula,ta; prothorace subquadrato, angulis anticis distinctis, lateribus 

 leviter rotundatis ad basim contractis, angulis posticis acutis, mar- 

 ginibus distinctis: elytris usque ad apices vix angustatis, apicibus 

 rotundatis, fortiter punctato-striatis; pedibus sat robustis tarsis 

 latis lineis coxalibus distinctis. 



A short and comparatively broad species; head and prothorax red, 

 very finely punctured, eyes finely granulate, antennae black with 

 base red, club 5-jointed; prothorax subquadrate, convex, gently rounded 

 at the sides, which are strongly margined, broadesc about middle, 

 contracted before base, posterior angles well marked; elytra of an 

 obscure greenish aeneous colour, parallelsided, very slightly rounded, 

 with strong andregularrowsofpunctures, interstices finely rugose, apices 

 jointly rounded, subtruncate just at suture: scutellum dark; legs 

 rather stout, pitchy, tarsi somewhat dilated, metatarsus of the hind 

 pair shorter than the two proceeding joints : coxal lines distinct, sub- 

 parallel, widening out towards apex. 



Length 10 — 11 mm. 



On example from Sokutsu, Banshoryo Drstrict 1912: another 

 smaller from Taihorin 1911. 



The smaller specimen has the club rather looser and the punctation 

 of the front parts rather more distinct, but it appear s to belong to the 

 same species on the one from Sokotsu. This insect is very distinct; 

 superficially it somewhat resembles Stenodastus (Languria) scutellatus 

 Crotch but differs in several important particulars: the red scutellum 

 in Crotch's species separates it at once from its allies. 



Anadastus formosanus sp. n. 



Subparallelus, sat nitidus, capite prothoraceque rufis, elytris 

 plus minusve obscure viridi-aeneis, scutello ruf escenti; capite triangulari, 

 levissime punctato, oculis prominulis, leviter granulatis, antennis 

 ad basim rufis vel rufo-piceis, clava nigra 5-articulata, prothorace fere 

 laevi, latitudine haud vel vix longiori, lateribus antice rotundatis
