Narrow and elongate in shape. Head usually with five spines, the 

 spines arranged as in related genera; bucculae closed in front; antenni- 

 ferous tubercles somewhat prolonged, obtuse. Antennae rugulose, 

 distinctly or indistinctly pilose, contiguous at the base; first and second 

 segments short; third segment long, cylindrical or subcylindrical, 

 obliquely truncate at the tip; fourth segment moderately long, more or 

 less lanceolate or ovate. The length of the antennae varies in different 

 species and sometimes a little in the same species. Rostral groove 

 uninterrupted, the rostrum varying in length in different species. 

 Pronotum tricarinate; paranota narrow, uniseriate (except in schwarzi), 

 folded back against or nearly against the pronotum proper; in schwarzi 

 the paranota are almost wanting, barely more than carinate and with 

 only two or three exceedingly narrow areolae near the anterior margin. 

 Metastemal orifices distinct. Hood indistinct or entirely wanting, 

 but quite large in some Mexican and Central American species. Elytra 

 extending considerably beyond the apex of the abdomen; discoidal and 

 sutural areas co-elevated; costal and subcostal areas varying in width 

 and number of rows of areolae in different species. Wings present.

1 — Subcostal area almost entirely biseriate 2. 



— Subcostal area uniseriate throughout 6. 



2 — Rostrum very long, extending beyond the apex of the rostral sulcus 4. 



■ — Rostrum much shorter, extending to or very slightly beyond the meso-meta- 



sternal suture 3. 



3 — Antennas varying slightly in length, usually barely reaching the base of elytra, 

 the third segment less than twice the length of the fourth; paranota with 



distinct areolse T. nigrina Champion 



— Antennae barely reaching the base of the elytra, the third segment slightly 

 more than twice the length of the fourth; paranota almost wanting, scarcely 



more than carinate T. schwarzi sp. new. 



4 — Insects 4 mm. or more in length; antennee moderately stout, very slightly pilose; 



lateral carinas diverging posteriorly 5. 



— Smaller insects, about 3.8 mm. long; antennas rather slender, distinctly and 

 quite densely pilose; lateral carinas parallel T. consors sp. new.
