LACE-BUG GENERA — DRAKE AND RUHOFF 11 



family Tingidae of the Hcmiptera. To the present authors, the wing 

 appears to be that of a homopteron, perhaps the family Psyllidae. 



In a recent paper Evans (1957, p. 289) placed Tingiopsis reticulata 

 in the family Cercopidae of the Ilomoptera. Until more specimens 

 are found that will provide better structural characters on the familial 

 level, the species should be left in family Cercopidae.

Chorology 



Faunal Divisions 



The partitioning of the world into faunal realms, regions, subregions, 

 and provinces has been a concern of zoogeographers for more than 

 a century. The basic concepts and features of faunal divisions were 

 formulated by such eminent scholars as Swainson (1835), Sclater 

 (1858; 1874), Darwin (1859), Huxley (1868), and Wallace (1876). 

 The recent book by Darlington (1957) on zoogeography and the one 

 by Lindroth (1957) on faunal connections between Europe and America 

 are classics in their respective fields. All of the above publications 

 also have been most helpful in charting the chorology of the existing 

 tingifauna by regions. 



Schmidt's (1954) schemes of faunal division and maps of the world 

 (figs. 2, 3) based on grid North Pole with continents radiating in 

 their relative positions have been followed rather closely. As our 

 data failed to lend themselves fully into the lower subdivisions of 

 provinces, the faunal tabulations of genera and of species were not 

 carried further than the subregions. For the same reasons the Carib- 

 bean Transition subregion and the Celebesian Transition province 

 were not included in the tables.
