244 SUPPLEMENT. 
CALLEROS (p. 25). 
Species which I find may be referred to this genus, or section of Plateros, have 
occurred now of various colours from black to yellow. The best distinguishing character 
(in addition to general facies) that I can offer is the simple structure of the antenne, 
which have elongate joints, with their inner apical angles scarcely acute. 
5. Calleros aterrimus. 
Ater, subnitidus; elytris parallelis; prothorace brevi antice paullo angustato, disco ineequali basi obsoletius 
fossulato. Long. 6-63 millim. 
Hab. Panama, Volcan de Chiriqui, 2000 to 6000 feet (Champion). 
In the Central-American series only one species is known to me as yet which is 
wholly black, or very nearly so, viz. P. carbonarius; from that the present species is at 
once distinguished by its evenly striate elytra and long thin linear antenne, which have 
the joints from the fourth onwards three times as long as wide and a little pubescent. 
C. aterrimus, however, almost exactly resembles the Japanese Plateros coracinus, the 
only apparent differences being that the latter has serrate antenne, and a duller, more 
quadrilateral thorax, with the fossa more clearly defined and open behind. 
Many specimens of this species were met with, chiefly at the higher altitude. 
6. Calleros filiformis. 
Elongatus, parallelus, ater; capite, prothorace elytrisque ochraceis, scutello cum prothoracis disco interdum 
infuscato. Long. 6 millim. 
Hab. Guaremata, San Geronimo, Volcan de Atitlan (Champion); Panama, Volcan de 
Chiriqui (Champion). 
Head ochreous, infuscate in darker examples; antenne about two thirds of the length 
of the body, the third joint shorter proportionally than in C. a¢errimus, but the same as 
in C. sinanje ; the following joints elongate and equal in length. ‘Thorax narrow with 
parallel sides, and rounded in front ; the disc faintly carinate in front, with an elongate 
sulcus behind sometimes deeper in the middle and before the base, and with its sides 
tumid and indistinctly fossulate on each side. Elytra very narrow and finely striate, 
the alternate coste a little raised. Three examples are all I have seen as yet of this 
species. 
CALODADON (p. 27). .[Catoczapon, Tab. II. fig. 20.] 
The former spelling was overlooked in the proof; that on the Plate expresses the 
intended form of the name. 
Calocladon testaceum (p. 28). 
To the localities given, add :—Panama, Volcan de Chiriqui, Bugaba (Champion).
