Obs, —Fig. 1 represents the insect magnified ; 1 a, the antenn?e of the usual form J 1 b, 
the antennae of another specimen, in the collection of ]\r. Dupont, where it is incorrectly 
named by him PI. Mclleii ? and which is rather darker than the ordinary specimens, but 
not otherwise distinct either in structure or markings. T presume this difference in the 
form of the clava of the antenn® may he sexual; at all events, I cannot regard it as a 
specific distinction, unaccompanied by other characters. 
Fig. 1 c represents the labrum, 1 d the mandible, the figure not numbered, to the right of 
which is the mentum, labial palpi and labium ; 1 e the maxilla seen from below; 1/the 
same seen more from within the mouth *, Iff the basal portions separated, and basal 
joints of the palpi; 1 k the maxilla with the palpi entirely removed ; 1 i, 1 Ar, and I /, 
the mando, and its basal piece, and the maxillary palpus seen in different positions; 1 m 
the extremity of the posterior tibia and tarsus.

P. latus, rufo-castaneus, elytris plaga magna triangulare ad basin alterisquc duabiis lateralibus, 
fascia que tenui irregulari ad apicem nigris; antennarum clava magna subrotundata mar¬ 
gine postico parum undulato, et versus basin late incisa angulo externo acuto. Long, 
corp. lin. 4.

Pitecedenti latior: rufo-castaneus, nitidus sub lento tenuissime luteo setosus et punctatus. 
Caput antice planum vix euiaiginatum linca tenuissima impressa e margine antico versus 
verticem extensa, impressionibus que duabiis vix distinctis ad marginem intemum oculo- 
rum ; antennarum clava magna fere rotundata, supra et infra fere seque convexa margine 
postico^ parum undulato, et versus basin incisione profundiori et latiori denteque multo 
acutiori armata. Protborax postice angustiorlineisque tribus transvereis vix distinguendis 
Elytra lata, rufo-castanea ad basin plaga magna communi dilatato-cordata, macuUque 
magna subtriangulari utrinque, fasciaque tenui irregulari apicali, nigris, Tibi® ad api¬ 
cem emarginatis in dentem externum acutum terminate. Fodex niger nitidus, 
Ohs. Fig. 2 a represents the lower parts of the mouth in situ (more correctly than in 
Trans. Ent. Soc. ii. pi, x., fig. 5 a.) 2 b the abdomen seen from beneath; and 2c 
the tarsus with the emargination of the apex of the tibia.
