LACE-BUG GENERA — DRAKE AND RUHOFF 9 



(1909, pp. 121-122) created two new divisions: Axiokersosaria, for 

 the reception of Axiokersos ovalis Distant, from India; and Aidoneu- 

 saria to hold Aidoneus dissimilis Distant. As the characters of these 

 two new divisions will not always separate them from genera of the 

 division Tingidaria, they are both synonymizcd here with Tinginae 

 (olim Tingidaria) . 



Since Distant's (1903c) work titled "The Fauna of British India" 

 is used so extensively in systematic studies, the present equivalent 

 taxa for the above divisions are listed here: 



Cantacaderaria, synonymizcd with subfamily Cantacaderinae. 

 Serenthiaria, synonymizcd with subfamily Agrammatinae. 

 Tingidaria, synonymizcd with subfamily Tinginae. 

 Axiokersosaria, synonymizcd with subfamily Tinginae. 

 Aidoneusaria, synonymizcd with subfamily Tinginae. 



Blatchley (1926) subdivided the subfamily Tinginae into three new 

 tribes for the reception of the genera occurring in eastern North 

 America. The status of these tribes is discussed below in the order 

 of their erection. 



Tribe Galeatini Blatchley (1926, p. 451) comprises the genera 

 Galeatus, Corythuca (error for Coryihucha), Stephanitis, Leptobyrsa 

 (not Stal), Corythaica, Dictyonota, Gargaphia, Gelchossa, Leptodiclya, 

 and Acanthocheila. Gelchossa is a synonym of Leptopharsa (p. 58). 

 Leptobyrsa is a South American genus not represented in the United 

 States. As used by Blatchely (not Stal), Leptobyrsa is synonymous 

 with Stephanitis, and thus Stephanitis blatchleyi Drake (1925b, p. 37) 

 and S. rhododendri Horvath (1905, p. 567) were wrongly transferred by 

 him from their original generic position to this genus. Galeatini is not 

 applicable for the inclusion of some of the American genera as well 

 as many related genera in the Old AVorld, and it is here suppressed 

 as a synonym of the subfamily Tinginae (p. 31). 



The tribal name Acalyptini Blatchley (1926, p. 479) was established 

 to hold the genera Acalypta and Drakella. As the latter is a synonym 

 of the former, only Acalypta is left in the tribe. Acalyptini is not a 

 valid tribe and thus is treated here as a synonym of Tinginae (p. 31). 



The tribal name Physatocheilini Blatchley (1926, p. 483) was 

 established to include the genera Physatocheila, Dichocysta, Tingis, 

 Teleonemia, and Leptoypha. The characters employed by Blatchley 

 in his tribal descriptions and key couplets do not correspond to those 

 of the genus Physatocheila itself, those of all the species of Teleonemia 

 of South America; nor those of some genera found in insular America, 

 South America, and the Old World. Thus, it becomes necessary 

 here to synonymize the tribe Physatocheilini with Tinginae (p. 31).
