Mercedes are somewhat intermediate in colour between the type and the variety from 
Cerro Zunil. One from Chiriqui has the elytra quite yellow. 
Telephorus mimetus (p. 90). 
To the Guatemalan locality given, add:—Cerro Zunil (Champion). 
3 (a). Telephorus (Silis) cephalotes. 
Niger, nitidus; capite (macula occipitali excepta), prothorace (disco late nigro-vittato), pedibusque basi flavis ; 
antennis sat longis articulis duobus apicalibus pallescentibus ; elytris substriatis, parum nitidis, ad humeros. 
indeterminate rufis. Long. 7-74 millim. ¢ Q. 
Mas. Prothorace oblongo, lateribus oblique sat profunde constrictis, segmento ventrali septimo fisso. 
Femina. Prothorace latiore, lateribus bisinuatis, angulo postico acuto, prominulo. 
Hab. Panama, Bugaba (Champion). 
Not unlike TZelephorus mimetus, but differing in the shape and structure of 
the head and thorax, and in being more shining. The head is yellow, excepting a 
spot at the base; the antenne have the two apical joints and half the preceding 
joint yellowish. In the male the thorax is elongate, with a deep lateral sulcus 
interrupting the margin obliquely; the disc is very uneven, broadly black, shining, 
and the base margined. The basal halves of the femora are yellow. The eyes in 
the male of this insect are conspicuously wider than the thorax. In the female the 
thorax is much more nearly quadrate. There is a very considerable likeness between 
this species and Stlis lineata, the females especially being hard to distinguish ; the 
males are, however, abundantly distinct, and we have received specimens of both 
species taken in copuld. 
5. Telephorus (Chauliognathus ?) hereticus. 
Nigro-fuscus, subopacus, subdepressus ; ore infra, coxis et femoribus, prothorace (disco excepto), elytrorum 
sutura et margine laterali tenuiter abdomineque flavis; tibiis fuscescentibus, tarsis nigris. Long. 7-10 
millim. 
Hab. Nicaracva, Chontales (Janson); Panama, Bugaba, Boquete, Volcan de Chiriqui 
2500 to 4000 feet (Champion). 
Head black, shining; epistoma, labrum, and mandibles, as well as the maxille 
outwardly and the whole underpart of the mouth, yellow; but the palpi are dark. 
Antenne a little compressed and widened in the middle, entirely black. Thorax very 
even, nearly quadrate, but with all the angles rounded; the disc blackish at the base, 
but this smoky black patch never touches the front margin, where it is only at the 
most shaded. Elytra dark or pale fuscous; the suture very narrowly, the margin 
less narrowly, yellow. Legs pale, touched with fuscous, especially at the tips 
of the tibie and tarsi. ‘The breast and abdomen are fuscous, the latter with paler 
margins; the lattér consists of six segments, with a very small seventh concealed within 
the small pygidial dorsal plate. At present I can find no difference by which to separate
