Lexithia, n. g. 



Caput rotundatum, verticale. Rostrum cylindricum, 

 parum arcuatum, sat elongatura, capite multo angustius ; 

 scrohes praeraedianse, infra rostrum exeuntes. Oculi 

 subtransversi. Scapus elongatus, clavatus ; funiculus 

 6-articulatus, articulis duobus basalibus longiusculis, 

 reliquis breviter obconicis ; clava late ovata, libera, arti- 

 culata. Prothorax subtransversus, utrinque rotundatus, 

 apice angustus, basi fere rectus. Scutellum distinctum, 

 minutum . Elytra lata, breviuscula, lateribus subparallela, 

 basi paulo incurvata. Pedes mediocres ; femora clavata, 

 mutica; tibice vix compressae, intus bisinuatse, apice 

 breviter unguiculatae, anticas flexuosse ; tarsi modice 

 dilatati; unguiculi libori. Abdomen segmentis tertio

The sole exponent of this genus is, comparatively, of 

 very small size, resembling Acalyptus rvfipennis, only with 

 much broader elytra, and is altogether different from

 can be placed. It is the only genus in the subfamily 

 with a six-jointed funicle.

 thorace apice rufescente ; olytris parce setulosis, pro-

The scales on the head and prothorax are only visible 

 under the microscope, they appear like grains of white 

 sand imbedded in the derm, a few being more hair-like 

 and partly erect.
