tertio longiore, sequentibus gradatim decrescentibus. Prothorax rotun- 
dato-ovatus, lateraliter dentatus, capite latior. Elytra elliptica vel

The first species of this genus was published and figured by Mr. 
White, in the Appendix to Stokes’s ‘ Discoveries in Australia’ (1846), 
under the name of “ Microtragus senex”’*, but without any attempt 
* Obrida is another genus barely mentioned in the same work ; at least, all 
that appears of it is just in this form:—‘“Clytus (Obrida) fascialis.” Then 
follows a brief description of the species. It is really difficult to know what to 
make of this style of nomenclature. Is it a Clytus? or, if something else, what 
has Clytus to do with it? The following are its characters :— 
OsRIDA. 
Caput porrectum, antice breve, tuberibus antenniferis obsoletis. Ocwli pro- 
minuli, reniformes, grosse granulati. Antenne breves, lineares, basi haud

sequalibus, quam scapo brevioribus, czeteris plus minusve longioribus. Pro-
