Ent. Soc. 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 O. zualkeri of the same author pro- 

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

 under the date of 1904 and quotes it, together with the walkcri 

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

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

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

 atensis will have to be used. 



P. 125. Dichromorpha brunnca Scudder is a color variety 

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



P. 127. Fencstra cannot be credited to Brunner as it was 

 used by him in an invalid manner, having 1 no species connected 

 with it. 8 The first writer to validate this genus by referring 

 to it a valid species was Giglio-Tos 9 who referred to it the 

 single new species bohlsii. which is therefore the type. The 

 genus Dichroatetti.r of Bruner, based upon the single species 

 viridifrons, is a synonym of Fencstra Giglio-Tos, its type 

 being synonymous with that of Fencstra as pointed out by 

 Rehn. 19 



Mr. Rehn was perfectly correct in replacing the genus 

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

 tctti.v and this genus should be used for the species listed by 

 Kirbv under Fencstra: these are pitlchripennis, intermedia, and 

 argentina of Bruner and Hncaris of Rehn. 



P. T2&,.Cn!oradeIIa was established by Brunner in 189^ but 

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

 name was by Bruner 11 who questionablv referred to it the 

 Stenobothriis brunnens of Thomas. This species, being a 

 questionably included one, cannot become a geno type accord- 

 ing to commonly accepted usages of nomenclature and thus 



8 Such genera are quite generally considered by entomologists as 

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

 such genera.
