pacifica group. Derotmema lentiginosum Scudder is also a 

 Trimerotropis and is synonymous with T. gracilis Thomas. 



Phyllonotus Hancock :|: was based upon three species, plagia- 

 tmn, sagrai, and saussitrci, all of which were soon afterwards 

 shown to really belong to the genus Choriphyllum of Serville. 

 This was all through an error of compilation, as later explained 

 by the describer, but the genus Phyllonotus as published falls 

 as a synonym of Choriphyllum and a new name is required 

 for the species intended to be placed under Phyllonotus. These 

 species are Cicada rhoinbea Linnaeus, Choriphyllum foliatiim 

 Hancock, and Choriphyllum u'cstwoodi Hancock, and for them 

 I propose the generic name Zaphyllonotum, of which foliatuni 

 may be considered the type. Phyllotetti.v Hancockf can not be 

 used for the above, as it sinks into synonymy under Choriphyl- 

 lum along with Phyllonotus, the genus for whose replacement 

 it was made. 



Orphulella walkeri Bruner (Ohio Nat., vol. vn, p. 11, 1906), 

 is preoccupied by Orphulella walkeri of the same author de- 

 scribed two years earlier (Biol. Cent.-Amer., Orth., vol. n, p. 

 73). The previous name was suggested to replace the Steno- 

 bothrns me.ricanus of Walker (which Bruner refers to Or- 

 phulella) in case that species is not proved a synonym of 

 punctata DeGeer. This is a reprehensible method of estab- 

 lishing new names, but, being published, the name has place in 

 ii'smenclatorial literature and can not be ignored. The later 

 species is from the same general region as the earlier one and 

 is said by the describer, in discussion, to be a possible synonym 

 of one of Walker's illy defined species of Stenobothrus. The 

 walkeri of 1904 was made to replace Walker's mexicana in 

 case it was found to be distinct and the zvalkeri of 1906 was 

 definitely described as a new species and merely suggested as 

 a possible synonym of one of Walker's species of Stenobothrus. 

 Thus these two species walkeri can not be considered as the 

 same conception and the later one, that of 1906, must fall. To 

 replace it I propose the new specific name losamatensis. 



Snodgrass (Proc. Wash. Acad. Sci., vol. iv, p. 439, 1902), 

 describes Sphingonothns trincsotis and says it occurs in three 

 varieties and describes these as chathamensis, indefatigabil en- 

 sis, and albemarlensis. As, by the laws of nomenclature, one 

 of the varieties of a species must bear the species name, I 

 designate the typical form as chathamensis, which name there-
