286 Mr. H. W. Bates' supplement to the 



Pentagonica angulosa. 



P. subcordicolli, Bates, siniilis sed differt ab omnibus 

 affinibus thorace utrinque biangulato ; nigro-nitida, 

 partibus oris pedibusque flavo-testaceis, antennis piceo- 

 fuscis, articulis 2 basalibus pallidioribus, thorace ely- 

 trorumque marginibus angustis rufescentibus ; thorace 

 valde transverso, postice ab angulo laterali explanato- 

 marginato, ante basin obtuse angulato, deinde usque ad 

 basin sinuato ; elytris punctulato-striatis, interstitiis sat 

 convexis. Long. 5 mm. 



Yuyaina ; Kashiwagi ; Nikko ; always in or about 

 fungi. 



The second angle on the sides of the thorax is distinct 

 also in P. hexagona, Woll., and P. suturalis, Schaum, but 

 in no species is it so well developed as in P. angulosa, 

 the explanated margin forming a distinct projection. 



Lebia fasca, Morawitz. 



Bates, Trans. Ent. Soc. Lond., 1873, p. 318. 



Miyanoshita and in Yezo. 



Described by Morawitz from examples taken at Hako- 

 date. The fourth tarsal joint, as stated by the describer, 

 is bilobed. 



Lebia duplex. 



L. fusca simillima, sed differt tarsorum articulo 4to 

 emarginato nee bilobato, thorace et elytris haucl distincte 

 rufo-marginatis. Long. 7^ mm. 



On all the islands ; on foliage in May. 



So near to L. fusca that there is scarcely any means 

 of distinguishing it except by the important structural 

 character of a simply emarginated fourth tarsal joint, 

 the same joint having two fully-developed lobes in L. 

 fusca. The form of every other part is as near as can 

 be the same ; but there appears to be a constant diffe- 

 rence in the margins of the elytra and thorax being 

 concolorous with the rest of the surface in L. duplex and 

 reddish in L. fusca. The elytra have deep impunctate 

 striae, with convex interstices, in both species.
