144 COELOCEPHALTJS. 



fusco-flavous. Elytra broader than the thorax, subparallel, equate, 

 punctate-striate (the punctures being broad, and the striae almost 

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

 at the apex. Antennce 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.

Mandibles concealed. 



Maxillary palpi (Tab. Y. fig. 8m) 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.
