20 U.S. NATIONAL MUSEUM BULLETIN 243 



History of the United States National Museum. In the case of the Union 

 of Soviet Socialist Republics, due to the uncertainties in some geographic 

 boundaries, it will be noted that both general areas (Caucasus, Crimea, 

 Siberia, etc.) and separate republics (Latvia, Dagestan, etc.) are used. 

 The term "Ostindien," as used by Fieber (1844), is vague and can refer to 

 either the East Indies or eastern India. Specimens from the Fieber collec- 

 tion deposited in the Naturhistorisches Museum, Vienna, bear simply the 

 label " Ostindien." 



As used in the text of this catalog, an asterisk (*) placed just before the 

 scientific name means that the species is represented in the U.S. National 

 Museum and a dagger ( |) indicates that it is a fossil species. Symbols or 

 marks used in the index only are explained immediately beneath the index 

 caption. 



Of the 1,820 valid species cataloged herein, 1,491 species are represented 

 in the U.S. National Museum. This number includes 669 holotypes (or 

 lectotypes) (of which 586 are in the Carl J. Drake collection and 83 in the 

 Museum collection). The Drake collection contains 1,482 different species 

 of lacebugs, of which 945 species are represented by a type of some kind.
