Pselaplddce of Japan. 305 



Mas, metasterno basi in medio angulariter bipromi- 

 nulo, trocbanteribiis posterioribus spinosis, abclomme 

 segniento ultimo ventrali impresso. 



Another very distinct species, allied, however, in many 

 respects to B. spinicollis ; the hind tibiae are armed with 

 a very short spur. 



Two males of this species were found at Miyanoshita ; 

 and a female at Ichiuchi, on the Kumagawa, 1st May, 

 1881. 



Batrisus angustus, Sharp. 



Sharp, Trans. Ent. Soc. Lond., 1874, p. 113. 



A second specimen of this species was found at Kiga ; 

 and another, with the front of the head rather differently 

 formed, at Nagasaki, on the 18th April, 1881. I am by 

 no means sure whether this latter individual is the male 

 of B. angustus or another species altogether. 



III. 1st dorsal segment twice or three times as long as %id, 

 its side-piece quite broad, though very distinct. Hind 

 tibia with long apical spur ; maxillary palpi tvith 

 more or less elongate terminal joint. B. puncti- 

 pennis, B. palpalis, B. acuminatus, and B. vestitus. 



The four species here associated are very distinct, B. 

 palpalis having a peculiarly slender elongate terminal 

 joint to the maxillary palpi, B. acuminatus an unusually 

 conical hind body, and B. vestitus a largely-developed 

 basal joint to the antenna, an enlarged cavity for its in- 

 sertion (in the male at any rate), and a tibial spur less 

 elongate than in the other species ; it approaches in 

 most respects to the species of Group VI., and its 

 affinities will require more consideration. 



Batrisus punctipennis, n. s. 



Gracilis, rufus, parce sed evidenter pubescens, antennis 

 fere gracilibus ; palpis articulo ultimo elongato, gracili, 

 capite lateribus pone oculos conspicue setigeris, vertice 

 utrinque longitudinaliter carinato ; prothorace elongato, 

 elytris hoc longioribus, intra humeros impressis, fortiter 

 punctatis ; abdomine segmento primo dorsali sequenti- 

 bus duobus paulo longiore, ad latera utrinque linea cur- 

 vata a margine remota ; tibiis posterioribus apice calcari 

 elongato. Long. 2 mm.
