PHILOTHERMUS. 493 
3. Philothermus cerylonicus, sp. n. 
Angustus, parallelus, depressus, ferrugineus, nitidus, antennis pedibusque testaceis; prothorace parce punctato ; 
elytris seriebus punctorum versus apicem et ad latera carentibus. 
Long. 13 millim. 
_ Hab. Mexico, Cordova (Sailé). 
_ Antenne small; club elongate, rather indistinctly divided. ‘Thorax about as long as 
broad ; front angles rounded, not. produced ; sides straight; the surface finely punctate. 
Elytra rather long, with series of fine punctures, which become obsolete towards the 
extremity and are absent from the sides; the sutural stria extends to the apex. Legs 
rather short. 
This is, perhaps, the smallest insect of the whole family. Itis exactly like a Cerylon, 
but the antennal club is as distinctly divided as it is in the type of Philothermus. 
4, Philothermus marginatus, sp. n. 
Piceo-castaneus, nitidus; antennis pedibusque testaceis; prothorace parce punctato, tenuissime pubescente, 
crasse marginato; elytris seriebus punctorum abbreviatis. 
Long. 2 millim. 
Hab. Mexico, Omilteme (H. H. Smith); GuateMmata, Capetillo, Zapote, Cerro Zunil 
(Champion). 
Antenne short ; club elongate, distinctly divided. Thorax rather strongly transverse, 
with the lateral margins very distinct; the hind angles well marked, almost acute; the 
surface very shining, with distant coarse punctures and a very few extremely fine hairs. 
Elytra very shining, with distinct series of remote punctures, none of them extending 
to the apex. Tibi slender. 
A North-American insect in Pascoe’s collection labelled “Cerylon testacewm, Say,” is 
closely allied to P. marginatus. 
5. Philothermus puberulus, 
Philothermus puberulus, Schwarz, Proc. Am. Phil. Soc. xvii. p. 361*; Horn, t. c. p. 5907. 
Hab. Nort America, Florida!?, Arizona?.—Mexico, Jalapa (Hége), Motzorongo 
(Flohr); Guatemata, Las Mercedes, Zapote, Capetillo, San Gerdnimo (Champion) ; 
Panama, Volcan de Chiriqui (Champion). 
The small series we have received of this species shows it to be somewhat variable 
in form and in the coarseness of the sculpture, but I am unable to see any good 
characters for separating the specimens. 
Schwarz + records it as having been found under the bark of Pinus palustris.
