LONGICORNIA. 295 
Cyllene cayennensis (p. 48). 
To the localities given, add:—Guatema.a, La Tinta in the Polochic valley (Champion). 
This species has only been recorded as yet from the Atlantic slope. 
7. Cyllene panamensis. 
C. cayennensi proxime affinis; differt solum antennis, pedibus et partibus oris testaceo-rufis, ventreque utrinque 
trimaculato. 
Long. 43 lin. 
Hab. Panama, Bugaba (Champion). 
Belongs to the subgroup which embraces C. acuta, C. cayennensis, C. caracasensis, 
and C. amazonica, which might almost be considered as so many local varieties of one and 
the same species. The colour is silky black, with three thoracic and four elytral fasciz 
(besides a short streak along the suture at the apex) ashy yellow; the second and third 
elytral fasciee are curved forward towards the suture, and are prolonged a little on the 
latter towards the base, and the fourth fascia is broken into a spot on the suture, and 
an oblique line across the disc. The reddish colour of the legs and the antenne alone 
-would scarcely suffice to distinguish the present form as a variety, but the character is sup- 
ported by the ventral segments having three large yellow spots on each side, instead of two. 
8. Cyllene antennata.

9. Cyllene ——? 
A specimen, with the apex of the elytra and abdomen wanting, taken by Dr. Palmer 
at Monclova in Coahuila, belongs to the same section of Cyllene which includes 
C. robinie and other North-American species, 7. ¢. the section in which the sides of 
the thorax near the base are rounded. In colour-markings it differs little from the 
C. erythropus group.

Trichoxys pellitus (p. 48). 
To the Mexican localities given, add :—Durasnal (Sai/é). 
Trichoxys vitticollis (p. 49). 
The specimens of this species, and also of T. sulphurifer, in the Sallé collection are

‘Playa Vicente.
