One species only of this genus has been described as yet, from Brazil; we now add 
three others from Central America.

Elongato-ovata, fusco-nigra, scutello ochraceo-pubescens elytrisque dimidio postico fulvo-ochraceo maculato vel 
variegato ; capite quam in gen. Zrenea multo minore angustioreque, confertim punctato, inter antennas 
concavo, fronte brevi infra paullo angustata, tuberibus antenniferis oblique elevatis; thorace subquadrato, 
basi angustato, tuberculo postmediano acuto, dorso plus minusve distincte tricalloso, scabroso-punctato ; 
elytris versus apicem gradatim angustatis, apice rotundatis, confertim punctatis, postice striatis interstitiisque 
convexis, tuberculo centro-basali paullo elevato ; antennis articulis basi anguste testaceis, scapo oblongo- 
ovato, basi intus subito angustato; pedibus sat gracilibus, femoribus gradatim clavatis, tibiis intermediis 
simplicibus ; tarsis articulo unguiculari elongato, unguibus subparallelis; mesosterno arcuato simplici, 
Palpi articulo terminali ovato oblique truncato. 
Long. 34-4 lin. ¢ Q. 
Hab. Guatemaua, Cerro Zunil, Panajachel (Champion). 
Resembles, in general appearance, the genus Alphus or Leptostylus much more than 
renea, to which it is really allied in structure. The claws are not so closely parallel, 
nor the claw-joints so thick, as in the “ Niphonini” and “ Apomecynini,” and they vary 
in degree of divergence in one and the same individual. Its characters bring it within 
the definition of the genus Penessada. 
2. Penessada albosignata. (Tab. XXII. fig. 21.) 
Oblongo-ovata, castaneo-rufa, glabra; scutello elytrorumque fascia (utrinque abbreviata) prope apicem cano-
