AN ANNOTATED LIST OF GENERIC NAMES OF THE COCCOIDEA 63 



Douglariella MacGillivray, 1921, The Coccidae, p. 474. 



type-species : Orthezia maenariensis Douglas, 1884, by substitution of this 

 generic name for Douglasia MacGillivray, 1921, preoccupied. 



MacGillivray replaced bis Douglasia, preoccupied in tbe Lepidoptera and 

 Coccoidea, witb Douglariella. Laing, 1922 : 254-255, synonymized tbe type-species 

 with Orthezia urticae (Linnaeus), making Douglariella a synonym of Orthezia 

 Bosc d' Antic. 



Douglasia Green, 1902, Victorian Nat. 19 : 95. 



type-species : Coccus floccosus De Geer, 1778, by original designation and 

 monotypy. 



Green proposed tbis as a subgenus. It was preoccupied in Lepidoptera by 

 Douglasia Stainton, 1854, according to Neave, 1939, Nomen. Zool. II : 151. In tbe 

 same year, but probably about a montb later, Green, Ent. Montbly Mag. 38 : 285, 

 published a practically identical paper, which proposed Newsteadia as the new 

 subgeneric name, with "D. floccosus" as the type-species. We assume that edi- 

 torial substitution was made for the preoccupied Douglasia since Green had 

 forwarded both papers from Ceylon. 



Douglasia MacGillivray, 1921, The Coccidae, pp. 110-111, 474. 



type-species : Orthezia maenariensis Douglas, 1884, by monotypy. 



Laing, 1922 : 254-255, showed that tbis name is a synonym of Orthezia urticae 

 (Linnaeus). In this usage Douglasia is doubly preoccupied. See two preceding 

 discussions. 



Douglasiella MacGillivray, 1921, The Coccidae, p. 483. 

 A lapsus for Douglariella MacGillivray. 



Drosiclia Walker, 1858, List of the Specimens of Homopterous Insects 

 in the Collection of the British Museum. Supplement, p. 306. 



type-species : Drosicha contrahens Walker, 1858, by monotypy. 

 This margarodid genus was reviewed by Morrison, 1928 : 163. 



Drosichiella Morrison, 1927, Biol. Soc. Wash. Proc. 40 : 105. 



type-species : Monophlebus tamarindus Green, 1918, by original designation. 



This genus is accepted as valid in Morrison, 1928 : 160, but Rao, 1950a : 114, 

 after examining the type specimens of tamarindus, reports that the genus 

 name is a synonym of Perissopneumon Newstead, 1900. 



Drosichoides Morrison, 1927, Biol. Soc. Wash. Proc. 40 : 106. 



type-species : Llaveia haematoptera Cockerell, 1917, by original designation. 



This genus was founded on the adult male only; its relationships to other 

 margarodid genera were discussed by Morrison, 1928: 171. 



Drosycha Signoret, 1875, Soc. Ent. de France Ann. (ser. 5) 5: 351. 

 A lapsus for Drosicha Walker.
