ANNULOSA JAVANICA. 45 



Obs. A Javanese species described by Wiedemann under the name of L. splendens comes 

 very near to this species, and his Languria tripunclata, a Bengal insect, scarcely differs from it 

 except in size and in its feet being altogether of a greenish black colour. 



88. Morio. L. nigro-nitida, capite ihoraceque punctatis, hoc Jbssulis duabus linearibus, elytris atro-ceneis 



puncto-striatis.

Caput nigrum punctatum labro piceo antennisque nigris. Thorax quadratus, punctatus, fossulis duabus 

 brevibus posticis longitudinalibus impressus. Scutellum nigrum. Elytra atroaenea striis septem 

 punctorum impressa. Corpus subtus pedesque nigri. 



89. Testacea. L. nitida, elytris punctato-striatis, antennis pedibusque nigris, coxisjemoribusque ad basin fer-

 Insectum supra ferrugineum. Caput subpunctatum, articulo antennarum basilari subferrugineo. Thorax 

 laevissimus. Elytra vix obscuriora striis octo punctorum impressis. Corpus subtus ferrugineum. 

 Obs. An insect which Fabricius describes from Sumatra, under the name of Trogosita jili- 

 formis (Syst. Eleuth. 1, 152, 12), comes very near to the above species ; indeed only differs from 

 it, according to the description there given, in that it has the elytra smooth. This, however, 

 may be an error of Fabricius, as the insect I have described above, under the name of Languria 

 testacea, appears to be widely dispersed, and occurring in my father's cabinet from the conti- 

 nent of India, seems not unlikely to be also a native of Sumatra. 



This insect clearly shews that Cerylon and other genera of similar structure are most erro- 

 neously placed by Latreille with the Bostrichidce, for it forms a most complete transition from 

 Languria to Cerylon.
