ANNULOSA JAVANICA. 45 
Oss. A Javanese species described by Wiedemaun under the name of L. splendens comes 
very near to this species, and his Languria tripunctata, a Bengal insect, scarcely differs from it 
except in size and in its feet being altogether of a greenish black colour. 
88. Morro. L. nigro-nitida, capite thoraceque punctatis, hoc fossulis duabus linearibus, elytris atro-cneis 
puncto-striatis. 
Long. corp. 2% 
Caput nigrum punctatum labro piceo antennisque nigris. Thorax quadratus, punctatus, fossulis duabus 
brevibus posticis longitudinalibus impressus. Scutellum nigrum. Elytra atroenea striis septem 
punctorum impressa. Corpus subtus pedesque nigri. 
89. Tesracza. L. nitida, elytris punctato-striatis, antennis pedibusque nigris, coxis femoribusque ad basin fer- 
ruginels. 
Long. corp. fere ;3; 
Insectum supra ferrugineum. Caput subpunctatum, articulo antennarum basilari subferrugineo. Thorax 
levissimus. Elytra vix obscuriora striis octo punctorum impressis. Corpus subtus ferrugineum. 
Oxss. An insect which Fabricius describes from Sumatra, under the name of Trogosita _fili- 
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 elytrasmooth. 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 Bostrichide, for it forms a most complete transition from 
Languria to Cerylon.
