64 THE CANADIAN ENTOMOLOGIST 



1900. Leonard!, Ibid., 8: 344. 



1903. Fernald, Catalogue Coccida?, 299. 



This genus was named by Leonardi in 1898 and its type was definitely 

 stated to be Mytilaspis metrosideri Maskell. Later (1900) Leonardi stated 

 that he found metrosideri to be a species of Aspidiotiis and he transferred the 

 generic name Anoplaspis to the species earlier named by Cockerell as Aspidiotus 

 hamhusarum, designating this as the type. This procedure is followed in the 

 Fernald Catalogue and Anoplaspis is placed as a synonym of Odonaspis in which 

 the species bambiisarum is included. The species Mytilaspis metrosideri Maskell 

 is placed under Lepidosaphes in the catalogue and no reference is given under 

 it to Leonardi's first paper. 



It is obvious that the first type fixation must stand and that the status 

 of the genus Anoplaspis depends upon that of Mytilaspis metrosideri, its type 

 species. 



A revision of the genera of Diaspinae must soon come for the group is falling 

 into confusion because of the many genera and subgenera that have been named 

 usually upon characters of no particular significance. Many of these names, 

 however, must be used, and it is desirable that such points as those discussed 

 above be straightened out. 



Synonymy of Some Species. 

 Targionia yuccarum Ckll. 



1898. Aspidiotiis yuccarum Ckll., Ann. Mag. Nat. Hist., (7), 2: 25. 



1900. Chrysomphahis {Melanaspis) tonilensis Ckll., Ibid., (7), 10: 470. 



1919. Targionia covillece (Ferris), Contrib. Knowl. Coccidae Sw. I'. S.» 

 Stanford Univ. Publ., 67-8. 



Mr. Morrison has called my attention to the fact that my Targionia coviUea 

 is identical with T. yuccarum (Ckll.), and has sent me a specimen of the latter 

 species. There is no doubt that the two are the same. Also, through the 

 kindness of Professor Cockerell, I have been enabled to examine a slide- of 

 Chrysomphalus tonilensis Ckll. from the type material, and this too prove- to 

 be the same. The species is a true Targionia as I have pointed out in the de- 

 scription of my T. covillece. 



Aspidiotus herculeanus Doane and Hadden. 



1909. Aspidiotus herculeanus Doane and Hadden, Can. Ent., 41: 29*^. 



1918. Aspidiotus subsimilis var. anonce Houser, Ann. Ent. Soc. Am 11 

 m.: 163; pi. 18, f. 1. 



The figure given by Houser indicates clearly that his A. subsimilis var. 

 anonce is identical with A. herculeanus, and Mr. Morrison, to whose attention 

 I have called this and who has examined specimens, agrees that this is the 

 case. I have had the privilege of examining a "type" slide of A. subsinUlis 

 Ckll. , and unlessintergrading forms exist there is no reason for placing herciilemus 

 as a "variety" of this species. 



Pseudodiaspis yuccae Ckll. 

 1896. Aspidiotus yucca Ckll., Psyche, 7; Suppl. 1, p. 20. 



1898. Aspidiotus yucca var. neomexicana Ckll., Ann. Mag. Nat. H:st.. 

 (7), 2 m.: 25. 



1899. Xerophilaspis parkinsonice Ckll., Ariz. Exper. Sta., Bull. 32 m.; '282.
