7. Platonica chiriquensis. 
Ferruginea, capite superne elytrisque fuscis, his basi ferruginea, pedibus testaceis; antennis brevibus, crassis, 
articulis 5°-10™ valde transversis; capite lato, sparsim fortiter punctato ; prothorace utrinque ante angulos 
posteriores obsolete oblique impresso; abdomine nitidulo, parum punctato. 
Mas elytrorum lateribus subtiliter marginatis, carina subhumerali parum elongata, ad angulum suturalem pro- 
cessu acuminato elevato; abdominis segmento 3° in medio plaga longitudinali parum elevata, segmento 6° 
carinula elongata ad apicem magis elevata. 
Long. 53 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet, Bugaba 800 to 1500 feet 
(Champion). 
Antenne ferruginous; third joint little longer than second, fourth small, fifth to 
tenth differing little from one another, each strongly transverse. Thorax sparingly and 
coarsely punctate, indistinctly depressed at the base in the middle, and with an indi- 
stinct oblique impression on each side, these depressions less distinct in the female than 
in the male; it is very transverse, the sides and base forming one continuous curve. 
There is a very scanty fine punctuation on the dorsal plates of the hind body, which is 
rather more distinct in the female than in the male. 
A series of three males and five females of this species have been sent by Mr. Cham- 
pion. Except in the sexual differences, they agree closely with one another, the unique 
female from Bugaba being, however, a little smaller. 
8. Platonica fuscicollis. 
Ferruginea, capite, thorace elytrisque (basi excepta) nigricantibus vel fuscescentibus, antennis in medio 
obscurioribus, articulis 5°-10™ fortiter transversis ; prothorace basi in medio late impressa; abdomine 
nitidulo, sparsim punctato. 
Mas elytrorum lateribus breviter marginatis, carina subhumerali elevata, ad angulum suturalem processu acumi- 
nato elevato; abdominis segmento 3° in medio plaga longitudinali parum elevata, segmento 6° carinula 
elongata ad apicem magis elevata. 
Long. 6 millim. 
Hab. GUATEMALA, Cerro Zunil 4000 to 5000 feet, Quiche Mountains 7000 to 9000 
feet (Champion). 
Although very closely allied to P. chiriquensis, this appears to be a distinct species. 
The individuals are slightly larger, and joints five to ten of the antenne are not quite 
so short. ‘The thorax is darker in colour, being fuscescent, with the margins more or 
less pale, and the basal impression in front of the scutellum very distinct: this is 
more or less distinctly divided into two by an elevation in its middle; and on each 
side of it, behind, the surface is a little elevated. The punctuation of the dorsal 
segments of the hind body is a little larger. The male characters are very similar in 
the two species. 
Nine individuals (three of them males) have been obtained. They exhibit but little 
variation. The specimen from the Quiche Mountains is not quite certainly the same
