The species of this genus are somewhat differing in form end appear- 

 ance. 'Vhile some mostly resemble Homalota , others come closer to Calodera . 

 From the former they are separated, inter alia, by the longer first joint 

 of hind tarsi, from the latter especially by, that the fore-tarsi are 4- 

 jointed. 



The body slender or very slender with differently shaped abdomen;

 the head porrect, feebly constricted behind, the constricted part at least 

 half as broad as the head between the eyes; antennae fine and slender; the 

 eyes rather large and more or less protruding; the temples well developed, 

 rounded off, not marginate; maxillary palpi slender, their second and third 

 joints very elongate, the third longest, the fourth very small and spiculi- 

 form; labial palpi slender. In the rest of the mouth-part structure Tachyusa 

 comes close to Homalota . 



Pronotum is most often distinctly narrower than elytra, as long as 

 broad or longer; elytra longer than pronotum, their posterior margin in- 

 side the outer corners incurved. Abdomen, which, v^hile the animals are 

 in lively motion as a rule is turned upwards, is slender, without side- 

 bristles, in some species rather of even breadth, in others strongly nar^ 

 rowing anteriorly. Ordinarily are not only its first three free dorsal 

 joints distinctly transverse-grooved depressed at base, and in several 

 species furthermore notably elongate (Fig. 88), but also its two-three 

 first ventral joints are at base distinctly constricted (cf. Homalota , 

 subg. Jnypeta) . The legs are long and slender; fore-tarsi 4-jointed, the
