Insectum Cephalotis habitu parvulum alatum vix huic generi associandum. Caput nigronitidum latitudine 
thoracis. Antenne articulis subaqualibus primo duobus sequentibus simul sumptis breviore, articulis 
quatuor ultimis crassioribus, apicali longiore ovato. Palpi maxillares articulo ultimo subulato cum 
tertio breviore quasi articulum unum fusiformem formante. Thorax convexus marginatus obcor- 
dato-truncatus, basi angustior, latior quam longus, medio vix canaliculato. Elytra striis sub lente 
distinctis, prima ad scutellum brevissima. 
Oss. Although I have assigned this little insect to the genus Trechuvs, Lam aware that it differs 
from it in many respects. The only specimen however in the collection is so mutilated, that I 
cannot venture to found a subgenus upon it, and therefore present as full a description of it as its 
being pasted down on paper will permit me to make. It agrees with the characters of Trechus 
given in the Regne Animal of M. Cuvier ; but these have been too vaguely drawn up to enable 
a beginner to form a correct idea of the genus. 
Subgenus GNATHAPHANUS Nobis. 
Antenne articulis fere equalibus secundo breviori. 
Labrum transverso-quadratum, angulis anticis rotundatis. 
Mandibule sub clypeo fere occult ; sinistra ad basin solum apparente. 
Palpi mazillares articulo ultimo subsubulato, tertio obconico breviori. 
Palpi labiales articulo ultimo preecedente breviore, subulato, acuto. 
Mentum breve, transversum, dente sinus mivimo simplice. 
Caput transverso-quadratum, latius quam longum, antice truncatum facie brevissim4. 
Thorax ut in Harpalo, sed fossulA lineari brevi utrinque postice impressus. Corpus 
oblongum. Elytra striis irregularibus punctisque discalibus, apice emarginata vel 
excisa. 
Oss. To this subgenus the Harpalus Thunbergi, of Schonherr appears to belong. It differs, 
however, from the following species, in being pubescent.
