1915] . Cavdell — Dendrotettix querciis (Packard) 53 



Bruner 1887, as there is no scientific name at all used. The second 

 reference, Riley 1888, is likewise passed over as no characters 

 are there mentioned. We now come to the third reference, 

 Packard 1890. Here a scientific name, Dendrotettix quercus, is 

 used in connection with a printed description of structural charac- 

 ters. This fills all requirements for the valid establishment of 

 genera and species and thus the genus Dendrotettix, with quercus 

 as type, is to be credited to Packard, the first to validate it. The 

 facts that Packard quotes Bruner's article of 1887, that he uses 

 Riley's manuscript name and that the characters are described 

 from immature specimens do not lessen the validity of the names 

 established. 



Now comes the question of the types of Dendrotettix quercus 

 Packard. It seems obvious that the types are the nymphs from 

 which Bruner drew up the description given in his article of 1887 

 and quoted by Packard in 1890. In the paper in which these 

 nymphs are described Prof. Bruner states that specimens accom- 

 pany the report, which was on an investigation made by him as an 

 agent of the Division of Entomology of the U. S. Department of 

 Agriculture. It is to be supposed that specimens of these nymphs 

 were included, and, indeed, there are now in the National Museum, 

 which has long been the depository of material gathered by the 

 Division of Entomology, three nymphs from Texas which are 

 evidently ones sent in by Bruner as they fit his description very 

 well and bear the collection label of Prof. Riley as did all mateiral 

 of this nature added to the collection in those days. One of 

 these three nymphs, a female with wingpads as long as the prono- 

 tum, is therefore here designated as the type of Dendrotettix quercus 

 Packard. 



That D. quercus is the long winged form is clear from the well 

 developed wingpads of the nymphs and from the statement in 

 Prof. Bruner's report of the extended flight of the adults. Thus 

 both specific riames, longipennis and quercus, pertain to the macrop- 

 terous form. 



Regarding the author of the specific name lojigipennis there 

 may also be some difference of opinion as the first use of that name 

 was by Bruner in 1891. But no differentiating character was 

 mentioned at this time, merely the statement that both long and 

 short winged forms occur. Dr. Riley in 1893 was the first to vali-
