MONOGRAPH OF THE COLEOPTEROUS FAMILY PAUSSID#. 
Descr.—Rufo-castaneus, supra subdepressus undique luteo tenuiter pubescens, nitidus sub lente 
tenuissime punctatus. Caput antice depressum margine antico parum elevato et in medio 
subemarginato, inter oculos subcanaliculatum canali in parte elevata postica in impressione 
profundiori terminato . Palpi rufescentes. Antenne rufo-castanee articulo apicali 
(clavi) maximo, prothorace majori fere ovato, basi tamen subemarginate truncato, 
supra in disco parum convexo, subtus magis gibboso, margine omni compresso acuto 
superne juxta basin (et cum eo parallela) impressione transversd, que ad marginem 
posticum in incisionem parvam et angustam desinit, angulo basali (dentem formante), 
externe subrotundato; incisione interne tamen fere recta, inde apex dentis snbobtusus 
apparet. Prothorax brevis transversus basi apiceque truncatus antice multo latior et 
elevatior, lateribus rotundato-dilatatis juxta vel paulo ante basin, subemarginatis, ibique 
depressus, et utrinque foved transversa brevi parva. Elytra prothoracis parte antica 
latiora et illo quadruplo longiora, oblongo-quadrata, basi transversim impresso, rufo- 
castanea, disco nigro plaga magna subtriangulari basali, sutura maculisque duabus posticis 
ovalibus relictis rufo-castaneis. Tibi dilatatee compress, angulo externo apicali preser- 
tim in posticis, acutis, 2-calcaratis. Corpus totum infra rufo-castaneum, segmento anali 
abdominis margine postico rotundato. 
Obs.—Fig. 1 represents the insect magnified; 1 a, the antenne of the usual form; 1 J, 
the antennz of another specimen, in the collection of M. Dupont, where it is incorrectly 
named by him Pl. Melleii? and which is rather darker than the ordinary specimens, but 
not otherwise distinct, either in structure or markings. TI presume this difference in the 
form of the clava of the antenne may be sexual; at all events, I cannot regard it as a 
specific distinction, unaccompanied by other characters. 
le 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 f the 
same seen more from within the mouth ; 1g the basal portions separated, and basal 
joints of the palpi; 1 % the maxilla with the palpi entirely removed; 1%, 1k, and UJ, 
the mando, and its basal piece, and the maxillary palpus seen in different positions; 1 m 
the extremity of the posterior tibia and tarsus.

Preecedenti latior : rufo-castaneus, nitidus sub lente tenuissime luteo setosus et punctatus. 
Caput antice planum vix emarginatum linea tenuissima impressa e margine antico versus 
verticem extensa, impressionibus que duabus vix distinctis ad marginem internum oculo-

Obs.—Fig. 2 a represents the lower parts of the mouth in situ (more correctly than in 
Trans. Ent. Soc. ii. pl. x., fig. 5a.) 26 the abdomen seen from beneath; and 2¢ 
the tarsus with the emargination of the apex of the tibia.

P. brunneo-castaneus ; elytris angustioribus, singulo macula magna Jaterali triangulari nigra, 
antennarum clava magna rotundata, subconvexa margine postico continuo at versus basin 
late incisa, dente acuto armato. Long. corp. lin, 3.
