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 large 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.
