Grote & Rohinson (Ann. Lyc. Now rork, viii. p. 364) romavk upon tho 
cliaractora of tho goniis ThyrU (III), fiom which they sopamto a now gonus, 
Platythyris, and propose to establish a family, ThyridcOj for Thyris and its 
allies. They roiuark that 'Thyris, tho liighest genus, imitates tho Sosiidm, 
whilst Platythyris, tho lowest, resembles tlio lower Castniid genera Alypia 
and Eudryas. The two genera are types of subfamilies, the Thyrini and 
Platythyrini. 2'hyris luyubris (Boisd.) will probably form a new genus 
lower still than Platythyris, 
Syntomina. Of the genera belonging to this group, which he 
regards as only artificially separated from the Arctiidee, Herrich- 
Schaffer gives the following table (Corr.-Blatt zool.-min. Ver.
