Ent. See. Wash., Vol. XI, p. 113 (1909), a specific name pro- 

 posed to replace the walkeri of Bruner, 1906 which was shown 

 to be preoccupied by the 0. zvalkeri of the same author pro- 

 posed in 1904. Mr. Kirby erroneously lists this later zvalkeri 

 under the date of 1904 and quotes it. together with the zvalkeri 

 of 1904, in synonymy under punctata DeGeer. The later de- 

 scribed zvalkeri, that of 1906, has nothing to do with the one 

 of 1904. It is a distinct species for which the name losam- 

 atensis will have to be used. 



P. 125. — Dichromorpha brunnea Scudder is a color variety 

 of Dichromorpha viridis, not a distinct species as here listed. 



P. 127. — Fenestra cannot be credited to Brunner as it was 

 used by him in an invalid manner, having no species connected 

 with it.* The first writer to validate this genus by referring- 

 to it a valid species was Giglio-Tos' who referred to it the 

 single new species hohlsii, which is therefore the type. The 

 genus Dichroatettix of Bruner. based upon the single species 

 viridifrons, is a synonym of Fenestra Giglio-Tos. its t\^pe 

 being synonymous with that of Fenestra as pointed out by 

 Rehn." 



Mr. Rehn was perfectly correct in replacing the genus 

 Fenestra as used by Bruner in 1900 bv the new name Cocyto- 

 tettix and this genus should be used for the species listed bv 

 Kirbv under Fenestra: these are pidchripcnnis. intermedia, and 

 ars^enfina of Bruner and linearis of Rehn. 



P. T28. — Cnloradella was established by Brunner in iSq-^ but 

 was invalid, having no included species. The next use of the 

 name Avas by Bruner" who questionablv referred to it the 

 Stenohothrus brmmeus of Thomas. This species, being a 

 questionably included one. cannot become a geno type accord- 

 ing to commonly accepted usages of nomenclature and thus 



* Such genera are quite generally considered by entomologists as 

 nomina nuda. This is certainly the only satisfactory way of treating 

 such genera.
