Mr. Kirby's Century of Insects. 425 



Corpus crassum, totum velutino-atrum. AntenncB clava magna, 

 compicssa, serrata, scptcmfida : articulo extimo bine subemar- 

 ginato. Ehjl.ra ante apicem lunula reversa, obscura, cinerea. 

 Anus aculeo ordinario. 



This species in every respect so entirely resembles the other 

 Mordcllcc, under which genus I only place those aiio aculeato, that 

 I do not conceive the difference of structure observable in its 

 antennae, which may perhaps be a sexual character, a sufficient 

 indication that it should form a distinct genus.

Gnathium Kirby. 

 Labrum transversum. 

 Labium minutissimum vix discernendura. 

 Mandibulic protensse, elongatse, apice incurvae, edentulae, acutis- 



simae. 

 Maxillcc apertae : lobo longissimo gracillimo. 

 Palpi filiformes : articulis cylindricis. 

 Mentum trapeziforrae ? 



Antemue extrorsum crassiores : articulo extimo elongato-conico. 

 Corpus obcuneato-lineare. 

 Thorax campanulatus. 



This genus comes next io Nemognatha Jllig., from which it bor- 

 rows that remarkable sexual ? character, of having the lobe of the 

 maxillae, like those of a bee, almost as long as the body ; but it 

 differs in having a transverse instead of a circular labrum, in its 

 mandibulae protended far beyond the labrum, in its incrassate an- 

 tennae, which gives it some connexion with Mylabris. The shape 

 of the head and thorax also is different. The insect is so minute 

 that I have not been able to get a clear idea of the shape of the 

 labium and mentum, but I think the latter is trapeziform.
