magno armatse, inde ad basin longe pnbescentes. Maxillce 

 (fig. 7 b) biloboe : lobo externo membranceo, longissime et 

 dense pubescenti : hUerno breviore, per marginem externum 

 usque ad apicem ipsum anguste et valde incrassato, uncum 

 obtuse incurvum efficiente, intus raembranaceo et dense pube- 

 scenti. Palpi maxillares articulo Imo parvo flexuoso, 2do 

 Stioque majoribus subaequalibus incrassatis, ultimo elongato, 

 fusiformi basi truncato : lahiales articulo Imo minuto, 2do 

 3tioque elongatis subsequalibus (illo subclavato, hoc fusiformi 

 basi truncato). Menturn corneum, tringulare apice truncatuin 

 et ibidem profunde excavatum. Ligula subcornea, apice in 

 medio longissime pencillata necnon ad latera paraglossis maxi- 

 mis angustis tenuissimis membranaceis divaricatis interne 

 ciliatis aucta. Pedes robusti : femoribus crassis, subquadrato- 

 oblongis : t'lbiis intus inermibus, curvatis (prsesertira anteriori- 

 bus) ; anticis (fig. 7 c) latis extus angulato-tridendatis ; inter- 

 viediis vix angustioribus, extus insequalibus et 4-spinosis ; 

 posttcis basin versus angustis, ante apicem subito leviter 

 dilatatis et ibidem extus bispinulosis ; anticarum angulo apicali 

 interno in spinam elongatam corneam curvatam exstantem 

 producto : tarsis articulo Imo elongato, 2do, 3tio, 4to bre-

 simplicibus munito. 



Obs. Genus funiculo distinctissime 6-articulato, capitulo 



abrupto solido, maxillarum lobo interno apice robuste (sed 



anguste) uncinato, necnon tibiarum anticarum angulo apicali 



interno in spinam corneam elongatam excurvatam producto, 



. inter genera Histeridum adhuc cognita anomalum. 



Ab kv, bene, et rp//3w, frico. 

 Amongst the forty-four genera of the Histeridce so elaborately 

 enunciated in De Marseul's Monograph, there is certainly nothing 

 which approaches the present one in its most distinctive features. 

 Indeed its 6-jointed funiculus would of itself suffice to characterise 

 it ; for the only known form in which this particular number of joints 

 (or in fact less than seven) prevails, in that portion of the antennas, 

 is Monopolius (of which hitherto but a single exponent has been 

 detected) from the Cape of Good Hope^ — an insect widely dif- 

 ferent from Eutripius in the other details of its structure. Its 

 various peculiarities will be easily gathered from the diagnosis ; 

 nevertheless I may just add that its two most anomalous ones 

 (apart from its funiculus) are the formation of its inner maxil- 

 lary-lobe and of its anterior tibiae,— the former of which is cu- 

 riously uncinated at its apex (the outer margin being thickened
