(Traus. Ent. Soc. vol. ii. p. 93.) 
Corpus subdepressum latiusculum. Caput thorace niulto angiistius postice in collum breve 
contractunij subtriangnlaro, antic^ truncatum subemarginatuai ; angulis posticis pone 
oculos subacute productis; vertice linca impresso. Palpi maxillares (fig. 3 o) maximi 
4-articulati, articulo Imo. brcvissimo ; 2ndo. maximo, interne scnsim ad apicem in lobum 
magnum acutum producto, articulis duobus apicalibus niulto minoribus subjcqualibus, 
ultimo obovali apice in vesiculam parvam terminate, Mentum cum capito baud articu- 
iatiim (3 a) transversum, nngulis aiiticis lateralibus acute productis denteque parvo 
breviori central! inslractum, palpi labiales 4-articulati, articulo Imo. parvo ci-asso, 2ndo. 
brevi annuliformi, 3tio. longiori apice latiori; ultimo praecedentis longitudine graciliori 
oblongo-ovato. Antennm maximte, ut videtur 7-articulataj, articulo Imo brevi ovali, 
2do. minutissimo, reliquis 5 lati&simis tnassam ovatam subdcprcssani^ disco marginibusque 
irregularibuB, formantibus. Prothorax latus lransversus,elytrorum ferelatitudine,depressus, 
lateribus anticis rotundatis et in lobum utriiiqtic productis, postico truncatis; portiouo postica 
prothoracis multo angusliori. Elytra lata oblongo-quadrata ; humeris antice et oblique 
productis: augulis posticis tuberculo ordinario munitis. Alee 2. Pedes satis graciles 
compress!, tarsis ut videtur, 4-articulati8, articulis 3bus. basalibus subaqualibus ;* (in 
certo situ rudimeutum articuU fere ad basin articuli ultimi apparet). Abdomen elytris 
paullo longius apice acumiuato, 4*annulatum. 
This genus appears to be intermediate between Platyrhopalus 
(with which it agrees in the comparative shortness of the terminal 
joint of the labial palpi and in the structure of the maxillary palpi,) 
and Pentaplatarthrus^ with which it might be associated, on account 
of the number of joints in its antennm. 
It is, however, abundantly distinct from these and the other genera 
of the family; whence I proposed a new genus for its reception, with 
a name alluding to the structure of the prothorax, which bears some 
resemblance to that of Lebia and Masoreus in the narrowness of its 
posterior part, although it will be evident that here it is the anterior 
lateral angles? and not the posterior part of the prothorax (as in 
those genera) which are dilated into lobes. Platyrhopalus aplustri- 
fer has the prothorax somewhat similar in form, but the antennse 
have the club not articulated, although with evident traces of con¬ 
strictions, and with the hind margin armed with spines.

Tcstaceus, supra subdepressus tenuissime punctatus nitidus. Caput porrectum subtriangulare, 
antice subcmargiualum, angulis posticis pone oculos acutia et paullo productis, vertice linea 
impressa notato. Antennaj piloscc, clava quasi 5»articulata, articulo Imo. reliquis minori 
traiisverso, tribus sequenlibua lalioribus, supra et aubtus Carina elovata instructis, ultimo

This species is named in honour of M. Hippolyte Gory, one of 
the authors of the “ Monographic des Cetoines,” by whose kindness
