NEMOCORYNA. 73 
species differ a good deal in the length and slenderness of the legs, but not to such an 
extent as to render it necessary to place them at: present in different genera. 
1. Nemocoryna godmani, sp. n. (Tab. III. fig. 9.) 
Nigra; capite thoraceque opacis; elytris versus suturam bistriatis, linea flava interrupta ornatis, externe 
seriatim punctatis, ad latus linea altera valde abbreviata ; pedibus gracilibus. 
Long. 18 millim. 
Hab. Panama, Volcan de Chiriqui 8000 feet (Champion). 
Antenne with elongate club, very different from the preceding joints. Prorostrum 
polished; metarostrum sulcate for its whole length above ; head narrowed behind the 
prominent eyes, the line of separation from the neck very slightly marked; side of the 
head with three very large punctures; sides of the metarostrum with numerous very 
large, almost confluent punctures, bearing a few very fine sete; under surface of the 
head and prorostrum polished, bearing two series of very large punctures, the central 
fovea very deep and definite, connected with the base by a fine channel. Thorax rather 
slender, much narrowed in front, the median groove a little abbreviate in front; the 
surface dull,impunctate. Elytra with two grooves near the suture, which are not very 
broad, but extend quite to the base; outside the grooves there is an elongate yellow 
line interrupted behind the middle ; outside this there are distinct series of punctures ; 
the carine of the declivity are remarkably abrupt. The legs are slender, the apical 
calcar of the front tibia very prominent. The breast and abdomen are not sulcate. 
Only one example was found of this very elegant and distinct Brenthid. 
2, Nemocoryna sericata, sp.n. (Tab. III. figg. 10; 10 a, antenna.) 
Chocolatina; capite thoraceque opacis; rostro canaliculato, ad latera parcissime setoso ; elytris dilutioribus, 
nitidis, impunctatis, ad suturam bisulcatis. 
Long. 17 millim. 
Hab. Paxama, Volcan de Chiriqui 3000 feet (Champion). 
Head and rostrum impunctate above; metarostrum with a fine channel on the 
middle extending all its length, and behind the eyes represented by two or three inter- 
rupted faint depressions; between the insertion of the antenne, on the pterygia, there 
is a faint elevation, over which the channel is continued ; in front of the pterygia it 
expands into a broad, deep, and elongate depression; sides of the metarostrum with a 
few coarse punctures, each bearing a curvate seta. Underneath, the base of the head is 
impunctate, and the median fovea is connected with the base by an almost imperceptible 
channel; in front of this are coarse irregularly-placed, not very numerous punctures, 
extending nearly as far forwards as the pterygia. The thorax is elongate, and though 
dull it has no punctuation. The elytra have two definite sutural grooves, and the suture 
is darker in colour than the other parts. The tibie are not lamellate, but rather slender. 
The breast and abdomen are not sulcate. |
