This new genus exhibits the characters of several of the groups 
of Cicindelidae. From Cicindela it is distinguished by the large 
size of the labrum, the unarmed mentum, the large labial palpi, the 
short antennae, &c. The same characters also remove it from Odon- 
tocheila Laporti, of which it has considerably the external habit, 
but a different thorax. From Therates, which it also much resem- 
bles, it is removed by the Jarge labial palpi, simple fourth joint of 
the tarsi, and by having an internal maxillary palpus. From Dro- 
mica its peculiar form and labrum remove it. It appears most 
nearly allied to Euprosopus and Iresia, agreeing with the former 
in the structure of the labial palpi, but differing in the labrum and 
mentum, and resembling Iresia in the form of the body, and in the 
peculiar style of punctation on the elytra, but having very different 
palpi.
