26 ANNULOSA JAVANICA. 



Genus LEBIA Lat. 

 49. Splendidula. L. rufa, oculis albis, thorace marginato, elytris striatis viridianeo-marginatis apice 

 truncatis. 

 An Lebia marginalis, Wiedemann Zool. Mag. Band. 2. s. 1. p. fiO ? 



Long. corp. -h 



Insectum omnino splendidulum corpore subangusto. Caput rufum clypeo inter antennas fossulato, labro 



magno quadrato, mandibulis latis inermibus apice acutis. Mentum lobis latis sed maxillarum basin 



haud tegentibus. Antennce articulo tertio brevissimo. Thorax truncato-obcordatus rufus medio 



canalicular. Scutellum inconspicuum rufum. Elytra abbreviata abrupt^ truncata pulcherrima. 



Corpus subtus nitidissimum rufum. Pedes rufi. 



Obs. This species comes so near to a Bengal insect described by Wiedemann as L. marginalis, 



that I must leave the separation of them to the entomologist who may have it in his power to 



examine both. 



Subgenus ORTHOGONIUS Dej. 



Antennce breves crassiusculse. 



Lahrum transverso-quadratum, antice emarginatum lobis rotundatis, singulo setis tribus 



antice instructo. 

 Mandibula inBequales', subtrigonss, lata?, superne convexse, angulatse, subtus concavag, basi 



subdenticulatse, apice acutissimse incurvee. 

 MaxillcB sinuatse apice latiores, latere interno rnembranaceo ciliato haud spinuloso vel 



setoso, processu dorsali articulo ultimo oblongo tenui ovato vel fusiformi; dorso pone 



palpos duobus tuberculis setigeris instructo. 

 Palpi maxiltares articulo primo brevissimo, secundo maxinio crasso obconico subincurvo, 



tertio obconico, quarto conico, his duobus quasi articulum unum oblongum ovatum 



formantibus, ultimo tertio breviore. 

 Palpi labiales articulo basilari (labii stipiti affixo) brevissimo lato, articulo secundo brevi ob- 

 conico vix subgloboso, tertio obconico prsecedentibus simul sumptis longiore, quarto 



prascedente breviore subconico vel potius subulato. 

 Labium angustum subcylindricum apice clavatum setis duabus instructum. Paraglossce 



labio haud longiores latse angulis rotundatis membranaceis ; Stipes labii magnus semicir- 



cularis menti sinum fere implens. 

 Mentum sinu edentulo seta utrinque instructo angulisque acutis. 



Caput facie antica setis sex instructa. Pedes unguibus subtus denticulatis tarsorumque 

 articulo penultimo bilobato. 



Obs. As M. Dejean has assigned a name to this subgenus in a manuscript catalogue, I have 

 thought proper to adopt it, although the genus is now for the first time characterized. It agrees 

 with the three former genera in having the ungues of the tarsi denticulated beneath, and the 

 elytra subtruncated at the apex ; but in most other respects of external appearance it differs 

 widely from the Brachinida; in general. It has the habit of a Nebria, and possibly approaches 

 to this genus or to Blethisa in affinity. Judging from the ciliated membranaceous maxilla?, 

 I suspect that this genus is not very carnivorous in its habits.
