GONICCELUS. 609 
The prosternal process is broader than usual and slightly flexed upwards. The 
sculpture of the flanks of the thorax is quite fine, as in G. wnicornis. The metasternal 
channel is short and fine. 
The unique individual appears to be, as I have said, a male: but this is not certain. 
There is no armature on the head and the excision at the base of the front tibia is 
smaller than it is in the male sex of G. parnoides and its immediate allies. 
10. Gonicelus cultratus, sp. n. 
Minus elongatus, ovalis, convexus, rufus, pube sat elongata suberecta vestitus, fortiter punctatus ; prothorace 
seriatim, fortiter, parce punctato. 
Long. 43 millim.

This is another species of which we have received only a single example. Though 
G. cultratus bears a certain resemblance to G. hirtus, it is really very distinct from it, 
and is characterized by the fact that the prosternum on the middle is marked with 
impressed lines that do not extend to the extremity of the process, nor do they reach 
the front of the prosternum. ‘The individual appears to be a male; it has a very 
minute tubercle on the middle of the head; the base of the front tibia, as in G. hirtus, 
has only a small excision, but, unlike that species, the correlative cultriform process at 
the extremity of the femur is unusually largely developed. ‘The antenne are short. 
The thorax is much narrowed in front, there is much coarse punctuation at the sides, 
the disc is convex, but is slightly longitudinally depressed on the middle, and on the 
median area has rather numerous coarse punctures subseriately arranged. The 
punctures of the elytra are rather large and distinct. The sculpture of the flanks of 
the prothorax is fine and regular. The prosternal process is a little bent upwards. 
The metasternal channel is fine and moderately deep. 
11. Gonicelus longicornis, sp. n. 
Ovalis, elongatus, posterius attenuatus, sat convexus, pube brevi dense vestitus, piceus ; antennis pedibusque 
rufis; prothorace punctis majoribus minus seriatis, ante scutellum impresso; elytris seriebus punctorum 
minus grossis. 
Long. 64 millim. 
Hab. Panama, Volcan de Chiriqui (Champzon). 
Although we have only females of this species, I must consider it as distinct from 
G. parnoides, from the corresponding sex of which it differs as follows:—the antenne 
are much longer, the marginal line of the thorax is quite distinct in the middle, and 
the smooth spaces near the sides of the thorax are indefinite. On the under surface 
the prosternal process is strongly bent upwards, and the metasternal channel is only 
fine. | 
This is undoubtedly a very distinct species, the much longer antenne distinguish it
