1478. Laccophilus flavescens, Motsch., Htud. ent., 1859, p. 45. Ceylon. 
“De la forme allongée et de la taille du Lace. basalis mais d’une couleur testacée roussatre, uniforme, 
4 Vexception des yeux qui sont noirs; les élytres sont trés finement pointillées, avec deux stries peu

que celle du notre L. minutus, mais moitié plus etroite.” . 
1479. Laccophilus hydaticoides, Regt., Ann. Soc. Fr., 1877, p. lxxix. Manilla. 
“Ovalis, vix elongatus, minime postice attenuatus, sat convexus; capite flavo; prothorace flavo 
latissime antice et postice nigro-limbato ; elytris nigris, angusto margine, vitta transversa irregulari ad 
basin, duabus maculis latis in disco, alteraque lata ad apicem flavis ornatis; subtus nigro-ferrugineus, 
pedibus testacies, posticis infuscatis. Long. 3 m.m.”

1480. Laccophilus lineatus, Aubé, Spec., p. 426. Mauritius. 
“Ovalis, apice paulo oblique rotundatus, depressiusculus, testaceus ; capite in vertice infuscato ; 
thorace antice et postice nigro-maculato, in medio brevissime acute producto ; elytris nigris, vitta 
transversa ad basin, lineolis plurimis longitudinalibus maculaque irregulari paulo ultra medium ad latera 
et altera ad apicem, rufo-luteo-ornatis. Long. 4, larg. 24 m.m.” 
[A description, 1. ¢., follows the above diagnosis. | 
1481. Laccophilus mexicanus, Aubé, Spec., p. 420. Mexico. 
“Ovalis, apice vix oblique rotundatus, depressiusculis, supra testaceus, infra nigro-piceus ; thorace 
postice in medio breviter acute producto; elytris pellucidis, creberrime brunneo-irroratis lateribus 
irregulariter testaceis. Long. 5 m.m., larg. 24 m.m.” 
[This diagnosis is followed, 1. c., by a description. | 
The species is probably the same as Laccophilus atristernalis (No. 104).—D. 8. 
1482. Laccophilus orientalis, Aubé, Spec. p. 431. Java. 
‘‘Oblongo-ovalis, 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 communi ad apicem brunneis, crebre testaceo-irroratis

ornatis. Long. 34 m.m., larg. 2} m.m. 
[This diagnosis is followed, |. ¢., by a description. | 
The species is perhaps allied to L. dispersus, (No. 161).—D. S$. 
1483. Laccophilus ornatus, Aubé, Spec. p. 432. Cayenne. 
“‘Oblongo-ovalis, apice paulo oblique rotundatus, depressiusculus, pallido-testaceus ; thorace postice in

[A description follows, 1. ¢., the above diagnosis. 
The species is perhaps near L. fumatus (No. 118).—D. S.
