Guiana, Cayenne}. 
Four males from Taboga Island agreeing with Dupont’s description and figure, except 
that the elytra are not narrowed at the apex, but obtusely rounded or subtruncated as _ 
in J. succinctus. In light-coloured examples a black fascia is faintly visible in the 
position of the white belt of the elytra of ZT. succinctus. In other colours, in the broad 
scutellum, and the roughened basal joints of the antenne the species resembles 
T. succinetus, of which it appears to be a variety or aberration. 
Trachyderes subpilosus (p. 89.) 
To the localities given, add :—GuaTEMALA, Cerro Zunil (Champion) ; Panama (Boucard), 
Volcan de Chiriqui (Champion). 
Trachyderes elegans (p. 90). 
To the localities given, add :—Mexico, Juquila, Cordova, Oaxaca (Sadlé), Almolonga, 
Tehuacan (Hoge); GuatemaLa, Coban (Champion). 
The following is a beautiful colour variety, somewhat resembling 7’. hilaris:— 
Var. T. eximius (Chev. MS.). Elytris nigris, fascia mediana (sicut in forma typica) testaceo-flava, macula 
utrinque basali, altera majori apicali, suturam attingente, aurantiacis. 
Hab. Mexico, Oaxaca (Sailé). 
The prevailing form of the species, judging from a large series obtained by Herr Hige 
at Jalapa, has light tawny-red or orange-brown elytra, with broadish black margins to 
the median band; this is named 7. vicinus (Chevr. MS.) in the Sallé collection. 
Individuals of 7. elegans sometimes approach very closely in colours light-coloured 
examples of 7. subpilosus ; in such cases the testaceous-yellow lateral margin of the 
elytra of 7. elegans, extending from the median belt nearly or quite to the shoulder, 
will prove a good distinguishing character. 
6. Trachyderes spinicollis. 
T.. succincto major, magis elongatus ; 7’. reichei (Dup.) et 7’. cingulato (Klug) affinis, antennis ( 9 ) scapo crasse 
clavato, fere levi, articuloque 3° gradatim sat valde dilatato-compresso. Castaneo-niger, elytris apice
