anterior angles of the thorax, and by the less coarse lateral punctuation, as well as by 
differences of the male and female characters. One pair. 
3. Gonicelus relictus, sp. n. 
[Femina.| Ovalis, parum convexus, nigricans, nitidus; elytris seriatim sat fortiter punctatis, pubescentia 
suberecta minus elongata sat dense vestitis; prothorace dorso punctato, linea marginali in medio 
interrupta. 
Long. 6 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Although we have received only a single female of this species its characters are 
sufficiently distinctive. It is the most elongate of this group, and in shape is very 
similar to G. unicornis: from the female of that species it is readily distinguished by 
the punctate disc of the thorax and the interruption of the anterior-marginal line ; 
while from the female of G. tricornis the more elongate form, the comparatively smooth 
head, the longer front angles of the thorax, and the disc of the thorax flatter and more 
evenly punctured, render it sufficiently distinct. The sides of the head are more 
elevated over the insertion of the antenne than they are in the allied species, and we 
may anticipate that the male will prove to have this part still more peculiarly formed. 
4, Gonicelus rudis, sp. n. 
Ovalis, sat convexus, nigricans; elytris seriatim fortiter punctatis, pubescentia suberecta sat dense vestitis ; 
prothorace dorso elevato, anterius in medio fortiter punctato. 
Long. 53-6 millim. 
Mas, capite ineequali, vertice in medio subtuberculato, utrinque vix plicatim elevato. 
Hab. Panama, Caldera in Chiriqui 1200 feet (Champion). 
Although very similar to G. wnicornis, this species is on comparison readily distin- 
guished by the more elevated, less polished disc of the thorax ; this elevation causes 
the angular fovea on each side of it to be larger and deeper. The anterior-marginal 
line of the thorax is uninterrupted in the middle and straight. The head of the male 
is very different from that of G. unicornis, and the thoracic horn is absent. The coxal 
lines of the abdomen are very distinct. 
5. Gonicelus germanus, sp. n. 
Ovalis, sat convexus, nigricans; elytris seriatim fortiter punctatis, pubescentia suberecta sat dense vestitis ; 
prothorace dorso elevato, anterius in medio fortiter punctato. 
Long. 53-6 millim. . 
Mas, capite ineequali, vertice in medio tuberculato, post tuberculum canaliculato ; prothorace margine anteriore 
rude discreto, in medio tuberculo minuto acuminato. 
Fem. linea marginali in medio obsoleta. 
Hab. Mexico (Sallé), Jalapa (Hége); Nicaracua, Chontales (Janson). 
Although extremely similar to G. rudis, this species is readily distinguished by the
