Corpus breve latum crassum ut in’ Cetoniis plurimis. Clypeus antice declivis, margine antico parum 
elevato. Antennarum articulus primus mediocriter triangularis. Mandibule lati crasse, parte cornea externa 
in dentem subacutum, paullo pone partem internam, producta (pl. TX, fig. 8¢). Maxille subelongate, galea elon- 
gata falciformi acutissima, mandonis apice in dentem integrum recte porrectum acutum producto (fig. 8d, max- 
illa supra visa). Mentum maximum os occultans, basi subeontracta basin maxillarum haud tegenti, parte 
apicali latissima lateribus rotundatis, disco concentrice striato, utrinque in margine excisum ad palporum basin 
suscipiendam (fig. 8c, mentum interne visum). Pronotum transversum convexum, margine postico emarginato. 
Prosternum ante coxas anticas in spinam deflexam antice setosam productum. Mesosternum processu antico 
haud porrecto et cum metasterno inter pedes medios conjunctum (fig. 8/). Pygidium convexum. Spiracula 
postica conoidea, Tibiz anticz bispinosie.

natis, brevibus, irregulariter foveolatis, foveis profundis, et striolatis ; abdominis segmentis lateraliter rotundato-

The original type of this species, formerly in Gory’s Collection, still, I believe, continues unique ; the parts 
of the mouth have been dissected away, so that both Burmeister (Handb. d. Ent. iii. p. 658) and myself are 
unable absolutely to determine its affinity to the type of the Genus, H. fu/igineus. The anterior margin of the 
clypeus is very slightly angulated in the middle. The sides of the pronotum are deflexed and longitudinally 
striated. The prosternal spine before the anterior coxw is so deflexed as to be scarcely visible (« ganz niedrig’, 
mit borstiger spitze.’ Burm.) The metasternal process between the middle feet is not porrected, but advanced 
to a point, received within the notched extremity of the mesosternum (fig. 7a). The lateral margins of the 
elytra are transversely rugulose, and the four basal segments of the abdomen are longitudinally impressed down 
the centre. The hind legs are wanting in the type specimen.
