7iew Species of Histeridae. 607 



sutural is apical and does not reach the middle ; the pygidia 

 are rather coarsely, evenly, and rather closely punctured ; the 

 propygidium has two rather shallow foveai which are apical 

 rather than basal ; the prosternum is smooth and without 

 striffi ; the mesosternum is sinuous and very clearly marginate ; 

 the anterior tibiae are 4-dentate. 



In form this species agrees closely with P. debile. Mars., 

 but the dorsal stride and the coloration are very different. In 

 outline it is also similar to P. depressum, Lee. 



Platysoma pygidiale^ sp. n. 



Ovatum, convexiusculum, nigro-piceum, nitidum ; fronte plana, 

 stria Integra late sinuata ; pronoto impunctato, stria Integra 

 mai'gine laterali parallela; elytris striis 1-3 integris, 4 apicali, 

 5 dimidiata ; propygidio transversim grosse punctato ; pygidio 

 anterius punctato, sed apice in totum Icevi ; prosterno angustato, 

 haud striato ; mesosterno sinuato, marginate ; tibiis anticis 

 4-5-dentatis. 



L. 2^-31 mill. 



This species frequently has a short discal sutural stria, 

 which is, however, not constant in length. P. pygidiale is 

 similar to P. eJingne, Lew., from Ceylon in its general facies, 

 while the scul|)ture of the pygidium agrees closely with that 

 of P. Confucii, Mars. The epistoma is wide in both elingue 

 and pggi'diale a,nd the fifth dorsal stria turns slightly away 

 from the suture anteriorly, especially in elingue, in which 

 species the stria is longer. 



Hah. Sumatra {H/RoUe). I have many examples, but no 

 special locality. 



Platysoma dorsale, sp. n. 



Ovatum, convexiusculum, nigrum, nitidum ; fronte impressa, stria 

 recta ; pronoto stria Integra, parum forti, margine laterali 

 parallela ; elytris striis validis, impunctatis, 1-3 integris, 4 dimi- 

 diata, 5 ultra medium abbreviata, antice sinuata, suturali brevi 

 media ; propygidio sat dense punctato ; pygidio dense punctato, 

 margine parte exteriore late lajvi ; prosterno inter coxas bistriato ; 

 mesosterno emarginato, stria Integra, in medio retrorsum acumi- 

 nata; tibiis anticis 4-5-dentatis. 



L, 3| miU. 



This species may be recognised from the known species 

 which resemble it by its short discal sutural siria, by the 

 fifth dorsal stria being anteriorly sinuous, by the prosternal 

 strife being confined to the region of the posterior lobe and 

 being joined before and behind, and by the mesosternal stria
