 simul sumptis breviore. 



Labrum breve, latum, trans versum, antice subemarginatum, medio quatuor setis instructo, 

 angulis rotundatis.

Maxillee subtrigonae intus setis ciliatae, apice ungue acuto armaio; processus dorsalis arti- 

 culo basilari obconico, apicali subcylindrico incurvo vix subulate 



Palpi maxillares articulo stipitali brevissimo ovato, secundo et tertio aequalibus boc obco- 

 nico illo incurvo subcylindrico apice subcrassiore, articulo quarto vel apicali breviore 

 obconico apice obtuso. 



Palpi labiales quasi mento affixi, stipite minimo tuberculiformi, articulis primo subobconico 

 et secundo subgloboso quasi articulum unum albo-annulatum versus apicem con- 

 stricturn formantibus, articulo tertio obconico intus setis duabus instructo, articulo 

 ultimo breviore seta una instructo, obconico, apice obtuso. 



Labium stipite occulto, obconicum lateribus subsinuatis, margine antico emarginato, angulis

Obs. This subgenus differs from Omaseits in having the elytra emarginate at the apex and the 

 middle tooth of the mentum simple instead of emarginate. It approaches also to Platysma 

 nigra in affinity, and has some relation to Cepkalofes Bon. (JBroscus Panz) ; but this is much 

 less remarkable than the former affinity.

Obs. This insect, of which a wretched figure is given by Olivier, is the largest and hand- 

 somest of the Javanese Adephaga. A piceous variety in my father's collection is the vcrv 

 specimen from which Olivier took his description and figure. Its identity, therefore, with the 

 above species is completely ascertained, and its nigropiceous colour in all probability merely 

 results from its having been a young insect when taken. 



Genus DICLELINDUS Nobis.
