Trigonosoma Nigellæ Fabr. 
Late obovatum, nigrum vel fusco-nigrum, superne minus dense 
subtiliter punctatum ; capite fusco-ferrugineo vel nigricante, æquilongo 
ac inter oculos lato, a latere viso perpendiculari, angulo faciali recto ; 
antennis flavo-testaceis ; rostro basin coxarum posticarum vix super¬ 
ante ; pronoto sulco anteapicali transverso instructo, parte anteriore 
abrupte declivi, a latere visa fere perpendiculari, flavo-testacea, parce 
subtilis simeque punctata, limbo lato apicali marginibusque lateralibus 
anticis fusco-ferrugineis, cicatricibus anticis nigricantibus, angulis hume¬ 
ralibus late rotundatis, parum prominulis ; scutello latitudine corporis 
ad basin illius distincte breviore, pone medium angustato et elytra 
occultante, basi transversim leviter elevato et fortiter rugoso-punctato ; 
margine imo costali corii basin versus flavo-testaceo ; pectore dense 
distincteque punctato ; ventre dense et subtilissime punctulato, limbis 
hujus lateralibus, connexivo, angulis posticis metastethii et pedibus 
stramineis ; segmento ventrali secundo haud sulcato ; segmento genitali

Species hæc, cum T. rustico Fabr. hactenus semper confusa, capite 
breviore, angulo faciali recto, rostro breviore, parte anteriore pronoti 
fere perpendiculari, segmento ventrali secundo haud sulcato, nec non 
capite, limbo antico marginibusque lateralibus pronoti obscuris et ventre 
semper nigro bene distinguenda.
