1472. Iljbius ovatus, Hoch., Bull. Mosc. XLIV, p. 237. Eiis.sia. 



" Perfecte ovalis, leviter convexus, niger, supra vix seneo-micans, elytris apicem versus oblique sub- 

 truncatis, lineis duabus rufo-fernigiueis fenestratLs. Long. 5 1." 



"Am nacbsten stelit diese art dem I. subasneus, Er., ist aber scliwarz, mit viel schwacheren griinlichen 

 schimmer als jener. Seine umriss unterecheidet sie von alien mir bislier bekannten arten ; diese 

 istein vollkommenes ovale, dessen breiteste stelle etwas hinter der mitte der Fliigeldecken fallt." 



1473. Ilybius suffusus, Crotch, Tr. Am. Ent. Soc. IV, p. 411. North America. 



" Closely resembling the two preceding (i.e., C. angularis, Lee, I. pleuriticus, Lee), but more allied to 

 I. pleuriticus by the less coarsely punctate tibise ; colour brassy, sculpture very fine, the whole margin of 

 the elytra broadly and irregularly ferruginous, hiding the usual pale spots. L. "44 inch. Indian 

 Territory." 



A female individual recently sent me by Dr. Horn indicates this as a very distinct species, whose 

 position is, probably but not certainly, near D. fuliginosus (No. 792), and I. meridionalis. — D. S. 



1474. Laccophilus adspersus. Boh., Ins. Caff. I, p. 246. Caffraria. 



" Oblongo-ovalis, convexiusculus, postice angustior, apice oblique rotundatus, testaceus, nitidus ; 

 prothorace immaculato, basi breviter acute producto ; elytris subtiliter, crebre nigro-reticulatis, lateribus 

 anguste pallidis. Long. 4, lat. 2\ m.m." Caffraria interior. 



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



I can form no opinion as to the species, except that it is unknown to me. — D. S. 



1475. LacoophUus baeri, Regt., Ann. Soc. Fr. 1877, p. Ixxviii. Manilla. 



" Ovalis, postice vix attenuatus ; capite testaceo, lineis duabus transversis et incurvatis giiseo-notato ; 

 prothorace testaceo, antice nigro-infuscato, postice linea transversa et leviter incurvata nigro-uotato ; 

 elytris fusco-nigiis, margine, lata ad basin transversa vitta, latissime apice magnam maculam inclaudente 

 et ssepe suturali linea flavo-ornatis ; subtus fusco-niger, pedibus testaceis, posticis ad tarsum infuscatis. 

 Long. 3J m.m." 



This species and L. transversalis are, it would appear, remarkable on account of the dark marks on 

 the head.— D. S. 



1476. Laccophilus cayennensis, Aub6, Spec. p. 434. Cayenne, Guadeloupe. 



" Ovatus, apice rotundatus, deprussiusculus, rufo-testaceus ; thorace postice in medio breviter acute 

 producto ; elytris creberrime nigro-irroratis, vitta irregular! transversa ad basin, maculis irregularibus ad 

 latera et apicem lineolisque brevibus in disco, pallido-ornatis. Long. 3^, larg. 2J m.m." 



\A descriptimi, 1. c, follows this diagnosis.^ 



1477. Laccophilus decoratus. Boh., Eug. Res., p. 20. Manilla. 



" Oblongo-ovalis, postice attenuatus, leviter convexus, subtus ferruginous, nitidus ; antennis capite 

 palpis, pedibusque flavo-testaceis ; prothorace dilute flavescente, antice posticeque medio leviter infuscato, 

 elytris piceis, luteo-iiToratis, fascia lata basaU, altei'a insequali infra medium introrsum abbreviata 

 apiceque dilute flavescentibus. Long. 3|, lat. If m.m." 



" Caput parum convexum, sub-lave, flavo-testaceum, nitidum. Palpi et antenme flavo-testacea. Oculi 

 convex! glauci. Prothorax longitudine triplo latior, apice medio subtruncatus, utrinque leviter sinuatus, 

 ba.si utrinque suboblique truncatus, medio vix triaugulariter productus, angulis anticis autrorsum modice 

 prominulis, sub-acuminatis, posticis fere rectis ; supeme leviter convexus, vix punctatus, dilute flavescens, 

 basi apiceque linea transvei-sa, utrinque valde abbreviata, dilute fusca ornatus. Scutellum nullum.
