interstitiis abdomineque esculpturatis. 
Long. 23 millim. 
Hab. Guatemata, San Gerénimo, Balheu (Champion). 
Head with a well-marked carina close to the eye and continuous with the anterior 
margin, and also with two short elevations on the vertex, otherwise flat. Thorax a 
good deal broader than long, the coste and depressions obsolete ; hind angles obtuse. 
Elytra nearly twice as long as the thorax; each with three very distinct regular carine, 
but with no sculpture or trace of other carine between them. Hind body quite 
destitute of sculpture. 
Closely allied to 7. rujficollis, but larger and with considerably longer elytra. Four 
examples.

6. Thoracophorus discretus. (Tab. XIX. fig. 14.) 
Rufo-niger, peropacus ; antennis pedibusque rufis; prothorace elytrisque obsolete costatis, illo vix transverso ; 
abdomine esculpturato, brevissime setuloso. 
Long. 13 millim. 
Hab. Guatemata, El Tumbador (Champion); Panama, Bugaba (Champion). 
Antenne rather large, much thicker externally. Head rather small; hind angles 
minutely denticulate immediately behind the eyes; the vertex obscurely bicarinate, the 
juxta-ocular carina distinct. Thorax rather broader than long, the surface uneven and 
with some obscure elevations but without definite carine. Llytra a little longer than 
the thorax ; tricostate, with an additional more obsolete carina between the first and 
second elevations. Hind body dull and rather rough; without definite sculpture, but 
sprinkled with very minute and short sete. 
This species is allied to 7. ruficollis, but is smaller and more depressed, has a longer 
thorax and shorter head and elytra, and slightly different sculpture. 
7. Thoracophorus pusillus. 
Subdepressus, opacus, fusco-ferrugineus; antennis, prothorace pedibusque rufis; prothorace elytrisque minus 
argute costatis, illo brevi.

Hab. Guatemata, Teleman (Champion). 
This insect is closely allied to 7. ruficollis, but only half the size, has a considerably
