This genus was confounded by Erichson! and other writers with Thoracophorus, 
Motsch.; Erichson refused to accept the latter name and proposed Glyptoma for the 
combination. Motschulsky? pointed out Erichson’s double error and corrected it by 
adopting the name Glyptoma for the species not belonging to Thoracophorus, Motsch. 
This course seems quite satisfactory and I now adopt it. In Glyptoma the anterior 
coxee are separated by a process of the prosternum, as in Lispinus, and the two genera 
should be placed in proximity, Glyptoma being distinguished by the abruptly constricted 
neck of the head and by its peculiar antenne. ‘The genus is confined to Tropical 
America and consists of three previously described species, viz. G. crassicorne, Er., 
G. punctatoplicatum, Solsky, and G. (Thoracophorus) opacum, Sharp, and the five new 
ones from Central America here recorded. 
1. Glyptoma leviceps. (Tab. XIX. fig. 10.) 
Nigrum, pedibus rufis, opacum ; capite convexo, levigato, nitido ; prothorace anterius in medio suleato ; elytris 
bicostatis ; abdomine basi vage sculpturato, apice levigato. 
Long. 4 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion). 
Antenne elongate, densely setose; penultimate joint slightly longer than broad. 
Head intensely black, polished and unsculptured. ‘Thorax with a broad short groove 
on the middle in front, the space outside this vaguely rugose. Elytra considerably 
longer and broader than the thorax; with a strongly raised curved costa on the middle 
of each, and a second rather less conspicuous one externally; the surface dull, with 
some vague depressions. Upper surface of the hind body with some vague depressions 
and sculpture on the basal segments, the apical segments unsculptured and rather 
shining ; under surface vaguely sculptured, the sculpture gradually more obsolete from 
the base to the apex. 
Two examples were procured under bark saturated with sap. The species is very 
distinct on account of its polished and shining head. 
2. Glyptoma longipes. 
Nigerrimum, pedibus piceis, opacum; capite medio levigato; prothorace anterius in medio sulcato; elytris 
unicostatis ; abdomine basi vage sculpturato, apice levigato. 
Long. 43 millim. 
Hab. Guatemata, Cerro Zunil 4000 to 5000 feet (Champion). 
Antenne very elongate, moderately setose; penultimate joint longer than broad. 
Head shining in front and along the middle, opaque on each side. Thorax coarsely
