592 CRYPTOPHAGIDZ. 
13. Tomarus heterocerus, sp. n. (Tab. XVIII. fig. 12.) 
Suboblongus, testaceus, thorace rufescente, elytris medio late fuscescentibus ; antennis ante apicem nigris, clava 
maxime elongata; fere impunctatus; prothorace fortiter transverso. 
Long. 27 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion). 
The unusual structure of the antenne is sufficient to characterize this species: joints 
7-10 are black, the terminal joint yellow ; joint 8 is small, but about as broad as long, 
ninth joint elongate, a good deal longer than broad, tenth a little shorter than ninth, 
eleventh a good deal smaller. Head broad. Thorax broad, but evidently narrower than 
the elytra, very little curved at the sides, slightly narrowed behind; basal impressions 
minute. Elytra yellow, with a fuscescent band behind the base. Metasternum not 
foveolate. ‘Two specimens. 
14. Tomarus ——? 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion). 
It is well to mention the existence of two specimens similar to 7. alectus and 
T. heterocerus in appearance, but having the sides of the thorax faintly crenulate. They 
appear to represent two species, but are not in sufficiently good preservation for 
descriptive purposes. 
15. Tomarus lentus, sp. n. 
Brevior, latus, subnudus, minus obsolete punctatus, fuscescens ; pedibus antennarumque basi et apice testaceis ; 
prothorace fortiter transverso, basin versus angustato; elytris testaceo-quadriguttatis. 
Long. 14 millim. 
Hab. Mexico, Teapa (H. H. Smith); Guaremaia, San Juan in Vera Paz (Champion). 
This little Zomarus may be distinguished by the short broad elytra, much narrowed 
behind, by the small eyes, and on the under surface by the unimpressed metasternum, 
which is finely margined between the middle coxe; the latter character separates 
it entirely from the 7. discoideus group of species, to which, in general form and 
the structure of the antenne, it bears most resemblance. Antenne rather small, joints 
6-10 black ; club short. ‘Thorax strongly transverse, much narrower than the elytra, 
distinctly narrowed behind, strongly lobed at the base in the middle, and with slight 
indications of a transverse impression; distinctly punctured; basal fove absent. 
Elytra distinctly punctured, shining, obscure fuscous, spotted with yellow at the 
shoulders and just in front of the apex ; sutural stria absent. Three specimens.
