CATENES, gen. nov. (To follow the genus Hereus, p. 205.) 
Head very long, strongly exserted from behind the eyes, the anteocular portion triangularly pointed in front 
and longer than the postocular area; antenne with the basal joint about reaching the apex of the head, 
second joint longest, third and fourth joints subequal in length. Pronotum long, twice as wide at base as 
at apex, constricted at centre, with the lobes about equal in length, the lateral margins sinuate. Scutellum 
about as broad at base as long. Clavus longitudinally punctate, its suture a little shorter than the 
scutellum. Rostrum slightly passing the posterior coxe, with the basal joint shorter than the head 
(imperfectly seen owing to the specimens being carded). Anterior femora moderately incrassated, and 
robustly spined beneath on their apical halves. 
The peculiar structure of the head will serve to identify this genus.
