" Ovalis, apice paulo oblique rotundatus, depressiusculus, testaceus ; capite in vertice infuscato ; 

 thorace antice et postice nigi-o-maculato, in medio bre\-issime acute producto ; elytris nigris, vitta

1481. Laccophilus mexicanus, Aube, Spec, p. 420. Mexico. 



" Ovalis, apice vix oblique rotundatus, dopressiusculis, supra testaceus, infra nigro-piceus ; thoi-ace 

 postice in medio bre\'iter acute producto ; elytris pellucidis, creberrime brimneo-iiToratis lateribus 

 irregulariter testaceis. Long. 5 m.m., larg. 2f m.m." 



[This diagnosis is followed, 1. c, by a descripiion.^ 



The species is probably the same as Laccophilus atiisternalis (No. 104). — D. S. 



1482. Laccophilus orientalis, Aube, Spec. p. 431. Java. 



" Oblongo-ovaUs, postice paulo angustior, apice oblique rotundatus, depressiusculus, supra testaceus, 

 infra obscurior ; thorace immaculato, postice in medio breviter acute producto; elytris pallido-testaceis, 

 vitta lata transversa fere in medio maculaque commiini ad apicem brunneis, crebre testaceo-irroratis 

 ornatis. Long. 3^ m.m., larg. 2-1 m.m." 



[This diagnosis is followed, 1. c, by a description^] 



The species is perhaps allied to L. di.spersus, (No. 161). — D. S. 



1483. Laccophilus ornatus, Aube, Spec. p. 432. Cayenne. 



" Oblongo-ovalis, apice paulo obliqvie rotundatus, depressiusculus, pallido-testaceus ; thorace postice in

 maculis irregularibus ad latera et apicem lineolisquebrevibus in disco, pallido-ornatis. Long. 4, lat. 24 m.m.' 



[A description follows, 1. c, the above diagnosis. 



The species is perhaps near L. fumatus (No. 118). — D. S.
