Ricania, Germar, Mag. der Ent. iii. p. 325 (1818). 
Ricania originally included a large number of species, many of which have now been 
assigned to separate genera. As here restricted, it is characterized by the broad, 
truncate head, which is scarcely or only slightly produced before the eyes, and has the 
front of the vertex strongly carinated; the distinct ocelli; the strongly tricarinate 
scutellum; the large and ample tegmina, which are widened towards the apex, and, 
as a rule, not or not strongly decumbent, with a distinct apical area furnished with 
more or less closely-set parallel veins; the often small wings; the usually bispinose 
posterior tibiz, which, however, are sometimes furnished with three distinct spines, 
and occasionally appear to have one only. 
1. Ricania bugabensis, sp.n. (Tab. VIII. figg. 7, 7 a.) 
Sat parva, fusco-brunnea; capite paullo ante oculos producto, truncato; pronoto interdum dilutiori, ad medium 
carinato; tegminibus amplis, fusco-brunneis, maculé apicem versus costali hyaliné, notisque nigris 
quibusdam in disco instructis; fronte et pectore testaceis ; pedibus plus minusve infuscatis. 
Rather a small species, of a dark fuscous-brown colour, with the front-parts sometimes lighter; forehead 
not carinate; pronotum about as long as the head, which is slightly produced ; tegmina ample, not or 
moderately decumbent, strongly veined, of a dark brown colour, with a light hyaline costal patch before the 
apex, and other more or less obscure light markings on the costa towards the base ; on the disc there are 
several rather large black impressed spots on each side, which are somewhat variable (they are very distinct 
on lighter specimens, but in the dark ones almost merge into the ground-colour) ; the apical veins are strong, 
and separated from the basal portion of the tegmina by a very distinct ridge; wings small; frons and 
chest and part of the abdomen testaceous ; legs testaceous, more or less infuscate. 
Long. 9-10 millim.; lat. ad hum. 5 millim. 
Hab. Panama, Bugaba (Champion). 
Several examples. 
2. Ricania feralis, sp.n. (Tab. VIII. figg. 8, 8 a.) 
Major, fusco-brunnea; capite vix producto, pronoto multo breviori; tegminibus amplis, cost4 antice dilatatd, 
regulariter, disco fortiter et irregulariter, transversim venosis, venis apicalibus dense dispositis ; colore 
unicolori, macula irregulari discali, alteré ad costam ante apicem, aliisque ad marginem apicis hyalinis ; 
corpore pedibusque fusco-testaceis.
