millim. ¢ Q. 
Var. capite nigro, ore et epistomate flavis. 
Hab. Mexico, Cordova, Toxpam, Cuernavaca (Sai/é). 
Head and thorax clear yellow and spotless; the antenne about two thirds of the 
length of the body, fuscous, the extreme base sometimes reddish ; palpi pale at the 
base, the apical joints of the maxillary pair elongate hatchet-shaped, of the labial 
triangular. Thorax shining, as wide as, or, in the female, wider than long, rounded in 
front; the basal margin slightly raised: on each side in the male is a minute notch or 
interruption of the margin. The elytra are greyish fuscous. The centre of the sterna, 
the cox, trochanters, and femora, excepting only their extreme tips, are reddish 
yellow. The abdomen is dark fuscous black ; in some specimens only the angles of the 
ventral segments are marked with ochreous. 
2. Discodon plicatum. 
Nigrum, nitidum, ore flavo ; prothorace glabro, aurantiaco, macula oblonga discoidali nigro-picea. Long. 10-11 
milliim. gQ. 
Hab. Muxico, Cuernavaca, Guanajuato (Sallé); GuaremaLa, Cerro Zunil, Panima, 
Duefias, and near the city (Champion). 
A species in its general appearance very much resembling rather small specimens of 
the European Telephorus rusticus, also not unlike T. picticollis (described hereafter) and 
other species. It may, however, be recognized by the shining head and thorax, by the 
oblong black spot on the latter, which in the Mexican specimens is continued till it 
becomes a complete vitta from the front to the base, by the black legs and underside, 
and, of course, by the generic characters. The claws are red; the anterior pair are 
furnished with a triangular membranous lobe on the inner side, and are not split; the 
intermediate and posterior ones have the outer claw of the male split, and with its 
outer division shorter and more bent than the inner one. 
3. Discodon incisum. 
-.. Flavum ; antennis, palpis pedibusque (basi exceptis) nigris. Long.11 millim. ¢ 9. 
. .. Var. femoribus fere totis, tibiisque testaceis. 
Hab. Guatemata, Duefias, San Gerénimo, Cerro Zunil (Champion). 
Very much of the size and colour of Telephorus bicolor, Fab. Body entirely testa- 
ceous; antenne fuscous or black, the basal joint usually in part yellow. ‘Thorax 
subquadrate, in the male a little narrower at the base than above the notch, the latter 
situated about one third from the hind angles, which are acute ; base finely reflexed ; 
disk with a shallow double impression. Underside, with the coxe, trochanters, and
