LACEBUGS OF THE WORLD 19 



A uniform method is followed in citing references. In the text and 

 synonymies the name of the author is followed by a year and page reference, 

 with the full tide appearing in the complete bibliography at the end of the 

 text. In case an author has published more than one paper in a given year, 

 the chronologic order is indicated in every case by an alphabetic affixation 

 to the years. 



The three subfamilies of Tingidae, their respective tribes, and the genera 

 within the tribes are arranged in alphabetical sequence, each in their 

 respective categories. The species are likewise arranged in alphabetic order 

 in their respective genera. Synonyms, homonyms, and other errata are 

 arranged chronologically under the valid specific name. Citations to other 

 catalogs, faunal lists, monographs, and keys to genera or species are in- 

 cluded in the generic citations. In addition to the original and later 

 descriptions, specific citations include references to illustrations, morphology, 

 biology, ecology, host plants, and distribution. Distributional records are 

 in summary by countries. The original technical name of the type species 

 of a genus always precedes the list of species. All elements in boldface type 

 are regarded as of equal taxonomic value. 



The incorporation of references dealing with biology, morphology, and 

 plant injury as well as those concerned with systematic entomology makes 

 the catalog a wide source of subject matter in different technical spheres. 



To obtain the full literature for any one species, the generic references as 

 well as those beneath the specific name should always be checked. The 

 specific references occurring in such publications as catalogs, lists of species, 

 and keys are listed beneath the generic names but not always beneath the 

 trivial unless illustrations or morphologic or biologic data are involved. 

 This combination of references (generic plus specific) includes the impor- 

 tant citations to each species. 



Information on the type (holotype or lectotype) specimen is recorded 

 when it was included in the original description, published later, or obtain- 

 able from an institutional deposition. As will be noted in the text, the type 

 specimens of a considerable number of species are either "lost" or "un- 

 known." For full account of the history and type fixation of tingid genera, 

 consult " Lacebug Genera of the World" (Drake and Ruhoff 1960a). 



The information on type locality is included as it was written in the 

 original description or as it appears on the locality label of the type specimen. 

 Political divisions, created by events in human history of the present day, 

 have made it ever difficult to keep pace with the changes in the names of 

 localities and countries for distributional records. Our efforts in up-to- 

 dateness have not been entirely successful. However, for such information 

 we have followed the maps recently published by the National Geographic 

 Society (Washington, D.C.), The Columbia Lippincott Gazetteer of the 

 World, Webster's Geographic Dictionary (rev. ed., 1957), and information, 

 current and historical, obtained from the Division of Philately and Postal
