Rhyparochromus plenus (p. 216). 
To the locality given, add :—Guatemata, Quiché Mts. 8000 feet (Champion). 
PETISSIUS, gen. nov. (To follow the genus Trapezus, p. 217.) 
Allied to Trapezonotus and Trapezus; from the first it differs by having the pronotum much broader than 
long and the head longer than broad, and from Trapezus by having the head, including the outer margins 
of eyes, about equal in width to the anterior margin of the pronotum. From both and from all the 
allied genera it is distinguished by the shape of the pronotum, which is much narrower at apex than at 
base, with the lateral margins non-ampliated. ‘The first and second joints of the antenne are sparingly 
hirsute ; the anterior femora are spinous beneath at apex, and the intermediate and posterior tibie are 
longly setose. 
1. Petissius assimilandus, n. sp. (Tab. XXXV. fig. 21.) 
Head black ; antenne ochraceous, with the apical joint infuscated, second joint slightly longer than the third, 
which is longer than the fourth. Pronotum ochraceous, with the anterior lobe mostly black and 
impunctate, the disk coarsely and darkly punctate, the punctures forming some longitudinal fascie on 
the posterior lobe, and being particularly thick on the sublateral and subanterior margins. Scutellum 
brownish, thickly covered with coarse black punctures, and with a central levigate and two lateral 
ochraceous fascie. Corium brownish, thickly covered with coarse black punctures, margins of clavus, 
margins of corium, and the veins ochraceous, and with a few small discal ochraceous spots. Membrane 
dark fuscous. Body beneath blackish ; legs and rostrum ochraceous. 
Long. 7 millim. 
Hab. Guatemata, Mirandilla (Champion) ; Panama, Bugaba (Champion). 
We have received four examples of this species. 
2. Petissius (?) diversus, n. sp. (Tab. XXXV. fig. 22. 
Body above reddish-ochraceous and pilose ; eyes black; scutellum and apical areas of the corium castaneous; 
antennee with the basal joint reddish-ochraceous, the remaining joints dull brownish; second joint a 
little longer than the third, third and fourth joints subequal in length; memtbrane pale ochraceous; body 
beneath reddish-ochraceous, legs pale ochraceous. The lateral’ margins of the pronotum and corinm are 
very narrowly pale ochraceous; the pronotum has a transverse impression; the corium is strongly 
pilose. 
Long. 3 millim. 
Hab. GUATEMALA, Paraiso, E] Reposo (Champion) ; Panama, David (Champion). 
We have received three (carded) specimens of this species, for which I hesitate to 
propose a new genus. It differs from the type of Petisstus by having the head 
including the eyes a little narrower than the anterior margin of the pronotum ; the 
other characters are, however, generally the same. 
EREMOCORIS (p. 218). 
2. Eremocoris germanus, n. sp. (Tab. XXXV. fig. 24.) 
Head black ; pronotum with the anterior lobe castaneous, with its lateral margins ochraceous, the posterior 
lobe black, with an ochraceous spot near the lateral angles. Scutellum pale castaneous, with the lateral
