FALICIANUS, gen. NOV. 
Head pointed in front, about as long as the anterior lobe 
of the pronotum ; eyes almost touching the anterior margin 
of the pronotum, ocelli much nearer to eyes than to each 
other ; antenne with the first jomt considerably passing the 
apex of the head, fourth joint much shorter than the second, 
a little shorter than the third, slightly longer than the first ; 
pronotum narrowed towards apex, deeply impressed across 
its centre, its lateral margins moderately sinuate at the 
incision and then rounded and moderately narrowed to apex, 
the anterior lobe moderately globose; scutellum somewhat 
tumid, flattened and hollowed near base; rostrum almost 
reaching the intermediate coxe, basal joit slightly shorter 
than the head ; anterior femora strongly incrassated, spined 
beneath, one spine very prominent; anterior tibiz slightly 
curved. 
Allied to Rhyparochromus, from which the relative lengths 
of the antennal joints will alone sufficiently distinguish it ; 
the pronotum is also less gibbous and the anterior and 
posterior lobes about subequal in length. 
Felicianus luteicornis. 
Rhyparochromus lutercornis, Walk. Cat. Het. v. p. 107. n. 178 (1872).

* The numbers in the anal fin (A.) include the two rudimentary anterior 
rays, and the last ray, cleft to the base, is reckoned as one ; the transverse 
series of scales is counted from the mid-dorsal to the mid-ventral line. 
The dorsal rays are constantly 10 or 11.
