268 SUPPLEMENT. 
CURIUS (to follow the genus Lampromerus). 
Curius, Newman, Entom. 1841, p. 17; Lacordaire, Gen. des Coleopt. vill. p. 352. 
Four species, reduced to two by Crotch, of this singular genus have been described. 
They are confined to the Southern States of N. America and Cuba. The following 
seems in some degree intermediate between Curius and Pentomacrus, White. 
1. Curius panamensis. (Tab. XIX. fig. 3.) 
Oblongo-linearis, depressus, breviter incumbenti-pilosus, opacus, fusco-testaceus; antennis, articulis apice 
exceptis, femorum pedunculis, tibiis et tarsis elytrorumque lituris, pallido-testaceis; antennis (¢) quam 
corpus duplo longioribus, tenuibus, pubescentibus et infra sparsim ciliatis, scapo gradatim clavato, articulis 
3° et 4° apice extus acute productis, 5° quam ceteri multo longiori (quam 4" duplo longiori); thorace 
valde elongato, cylindrico subdepresso, punctulato, opaco; elytris apice conjunctim acute rotundatis passim 
creberrime punctulatis, fascia angusta antemediana, macula triangulari suturali versus apicem, apice et vitta 
irregulari marginali pallide testaceis ; pedibus valde elongatis, femoribus longe pedunculatis, clavis subtus 
acute dentatis.

2. Obrium pallidum.

Phyton limum, Newm. Entom. 1841, p. 18’. 
Hab. Norta America, Southern States! ?.—Mexico, Presidio (Forrer). 
8. Obrium lituratum. (Tab. XIX. fig. 6.) 
O. pallido proxime affine et simile; differt elytris multo longioribus. Pallide testaceum, setosum, nitidum ; 
capite fasciis duabus (frontis et verticis), thorace vittis tribus, elytris utrinque lineis quatuor (prima et 
secunda parallelis subapproximatis obliquis retrorsum versus suturam, tertia elongata fere suture parallela, 
quartaque parum obliqua prope apicem) nigro-fuscis, plaga discoidali pallidius fusca; pectore nigro ; 
femorum clava fusco-annulata basi fusca; tibiis basi excepta nigro-fuscis ; antennis articulis apice fuscis. 
Long. 23-33 lin. ¢ @. 
Hab. GuatTEMALa, Cerro Zunil 4000 to 5000 feet (Champion). 
Var. Caput immaculatum, elytris linea fusca tertia (suture subparallela) deficiente. 
The thorax is decidedly narrower than in O. pallidum and O. cordicolle, the dilatation 
behind the anterior constriction not being abrupt as in those species, and the middle of 
the sides being angulated.
