90 MALACODERMATA. 
2. Telephorus rugipennis. 
Griseo-niger, subnitidus, subtus flavus ; epistomate, prothorace postice pedibusque basi rufo-testaceis ; protho- 
racis disco postice fossa haud profunda; elytris subrugose fortiter punctatis, lineis duabus subelevatis. 
Long. 64-73 millim. 
Hab. Guatemata, Zapote (Champion). 
Head narrowed and rounded behind; mouth, mandibles, palpi, and base of the 
antenne: pitchy red. Apical joint of the maxillary palpi triangular. Thorax suborbi- 
culate, the margin a little reflexed, hind angles a little acute and turned out, the base 
sinuate ; immediately before the centre of the base is a squarish shallow fossa, which, 
with the front half of the thorax, is black. Underside yellow, with the exception of 
the breast, which is leaden black, and a cloud on the middle of each ventral plate. 
The coxe and femora are pale yellow; the knees, tibie, and tarsi dark. ‘The antenne 
reach a little further than the hind coxe. There are only three specimens which agree 
with this. The rough elytra and peculiarly coloured thorax sufficiently distinguish it ; 
but I am not able to determine the sex of these specimens. 
8. Telephorus mimetus. (Si/is?) 
Niger, subopacus ; ore, epistomate et mandibulis, prothoracis lateribus calloque humerali rufis. Long. 6 millim. 
Hab. Guatemata, Zapote (Champion). 
Extremely like Stlis nigrita, but with the head of a different form, more exserted, 
and with smaller eyes, which are not so globular. The antenne are black, scarcely 
reaching the hind coxe. The thorax is narrower than in S. nigrita, and with the 
sides bisinuate as in the female S. hematodes &c.; the hind angles are acute and a 
little projecting outwards; the disk is opaque, uneven, with a wide shallow depression 
in the centre of the base. The elytra are opaque black, with only the humeral callus 
red; there are obsolete indications of striae, and very obsolete puncturing. 
Two specimens are all I have seen. In size and colour this insect also exactly 
resembles various Platerotes of the striatus group, some Caloptera, and a variety of 
Silis varians. The prominent trapezium-shaped head with red jaws and the form of 
the thorax are the best general distinguishing characters. 
4. Telephorus comptus. 
Niger, subopacus ; prothorace transverso, late rufo, disco nigro, inequali, postice tuberculo duplo, lateribus 
reflexis, fortiter rotundatis, angulis posticis subrectis, minute productis; antennis compressis, serratis, ad 
apicem attenuatis. Long. 9 millim. 9. 
Hab. Guatemaa, San Geronimo (Champion). 
There are only two specimens among Mr. Champion’s collections, which agree in 
having a decidedly transverse thorax with reflexed margins, the disk uneven, and with 
a double tubercle, somewhat in the manner of Discodon bivittatum, behind. ‘The head 
is squarish, the mouth and middle of the underside being pale; it is small for the size 
of the insect. The antenne reach about to the posterior coxe; they are entirely black.
