Latreille (Prec. Car. Ins. p. xiii) proposed the name 

 Astata for a genus which he promised to describe later, 

 stating, at the same time, that he had intended to call it 

 Astatus, but wished not to do so to avoid confusion with 

 his genus Astacus {Crust.) — in the body of the Avork (p. 114-5) 

 the genus is described as Astatus. 



Having no exponents Astata (Astatus) Ltr. had no 

 scientific status until 1802, and could not in the mean- 

 time preoccupy the same name used in another sense by 

 another author — Astatus Jurine (proposed in IVIay 1801) 

 for a genus of Tenthredinidae, with properly designated 

 exponents, is therefore a valid name, and its exponents 

 being all synonyms of one species [pygmaeus L.) the genus 

 is virtually a monotypical one. 



In 1807 Jurine proposed a new name Trachelus in lieu 

 of Astatus Jrn., remarking (Nouv. IVIeth. Hym. 72) :
