144 CCELOCEPHALTTS. 



fiisco-flavous. Elytra broader than the thorax, subparallcl, equate, 

 punctate-striate (the punctures being broad, and the stria) almost 

 obsolete), finely pubescent ; dark fuscous, suffused with ferrugineous 

 at the apex. Antennae tolerably long, robust ; the first joint broad 

 and long (extending, when placed horizontally, beyond the outer 

 margin of the eye) ; the second short, narrow ; from the third to the 

 sixth the joints are gradually but strongly incrassated, so that the 

 sixth joint is nearly three times the breadth of the second ; the rest 

 of the joints are abruptly and finely filiform, the seventh being 

 slightly larger, and the eighth to eleventh narrower and longer than 

 the second ; in colour, the joints first to third are flavous, the fourth to 

 eleventh rufous, the fifth, sixth, and apex of the eleventh being rufo- 

 fuscous. Legs : the anterior flavous ; the postical flavo-ferrugineous. 



From the district of the River Amazon.

Palpi maxillares elongati, art. pemdtimo cylindriro, ad basin sub- 

 constricto, art. ultimo brevi, hand attenuate-. 



Palpi labiales cylindrici, minuti. 



AxTEXN^^Z/ybrwes, elongate;, elytris duplo longiores. 



Caput breve, antice productum, verticale. 



Thorax quadratus, rectUinearis, ad basin subconstrictiis.

Mandibles concealed. 



Maxillary palpi (Tab. V. fig. 8 m) elongate; the second joint 

 truncate at its apex ; the penultimate somewhat broader, cylindri- 

 cal, its length being double its breadth ; the apical joint is broadly 

 conical.

Antenna* approximate, situated at the anterior angle of the head, 

 filiform, attenuate, elongated ; in form, length, and position closely 

 corresponding to the antennae of Loxoprosopus ; the first joint is broad, 

 dilated, and incurved outwards towards the apex ; the second short 

 and ovate, the following elongate and attenuate, the whole being 

 twice the length of the elytra. 



Eyes globose, situated at the base of the head, and extending late- 

 rally as far as the anterior angles of the thorax.
