Amyot as generic names and credited them to Amyot as such. This 

 is a serious error. Since Amyot's names are not true generic names 

 and have no nomenclatorial standing, they are not included herein in 

 the present treatise of the generic names of Tingidae of the world. 

 The authors hope that the above comments will prevent further 

 confusion and use of these monomial names. 



In his catalog of the Hemiptera, Walker (1873, pp. 175-179) in- 

 cluded only two families, Tingididae and Piesmidae, in the Mem- 

 branacea, and divided a number of tingid genera into "Divisions" 

 and "Subdivisions." For the new taxa below the generic level, 

 Walker used a jumble of scientific names of other workers. These 

 names were wrongly employed, wrongly synonymized, and wrongly 

 classified by him. Since no new generic or subgeneric names are in- 

 volved, the present authors are following previous catalogers and 

 omitting Walker's names of generic and subgeneric divisions. 



The proper form of the family name of the lace-bugs was an item 

 of contention for more than a century. The moot point of the con- 

 troversy rested almost entirely upon finding the correct "root" and 

 "stem" of the type generic term Tingis of Fabricius. These items 

 have been amiably and consummately investigated by Holland (1922a; 

 1922b; 1924), Baker (1922; 1923), Parshley (1922a; 1922b), and 

 Schmitz (1935). Their findings showed much diversity of opinions 

 and little unanimity as to the origin and status of " Tingis." 



In January 1923, Baker submitted to the International Commission 

 of Zoological Nomenclature a concise summary of the findings and 

 conclusions on the controversy of Holland, Parshley, and himself, 

 including a request for a ruling on the origin and formation of the 

 word "Tingis." To quote from Opinion 143 of the International 

 Commission of Zoological Nomenclature (1943, pp. 83-85): 



Tingis dtant un nom latin dont le genitif est Tingis et l'accusatif Tingim, 

 TINGIDAE est la forme correcte du nom de la famille. 



The ruling was: 



The family name for Tingis Fabricius, 1803 (Syst. Rhyng.: 124) in the Hemip- 

 tera is TINGIDAE. 



Beginning with volume 59 (1922), the Zoological Record has con- 

 tinually used the family name Tingidae for the lace-bugs. That 

 spelling under the R6gles has been universally accepted as the proper 

 family name for the lace-bug family. 



Stal (1873, p. 116) and Distant (1903c, pp. 122-145) both used the 

 higher categories as divisions for the family Tingidae, although 

 Distant placed a few genera in the wrong division. These categories 

 were Cantacaderaria, Serenthiaria, and Tingidaria. Later, Distant
