HYMENOPTBROUS PARASITES OF COCCID^. 95 



75. Dactylopius longispinus, Targ. 

 Two species, Coccophagus orientalis (Proc. U. S. Nat. Mus. 

 1896, p. 633) in Ceylon, a,nd Eucomys (Encyrtus) albicoxa, Ashm. 

 (Trans. Amer. Ent." Soc. 1885, Proc. p. xvi.) from N. America, 

 have been recorded from the synonymous D. ado7iidum, Targ., 

 the "Mealy Bug." 



76. PSEUDOCOCCUS. 



Newstead says (Mon. Coccid. i. 32) that he has bred Aphycus 

 Pappus, Walk., freely from uninstanced species of the genus at 

 Weston-super-Mare, Norfolk, and Cheshire: that it was, in fact, 

 often difficult to find an unaffected female; and Howard tells 

 him that he bred a specimen of the Proctotrypid Lygocerus 

 hyalinatus, Thoms., from (probably some dipterous larva in) 

 Pseudococcus. 



77. Pseudococcus yucca, CoquiL* 



Perissopterus mexicanus. How. (Revis. p. 22) in Mexico, and 

 Blastothrix yuccce, Coquil. (Ashm. 1900, p. 390) from California, 

 prey upon this species. 



78. Pseudococcus aceris, Sign. 

 The omnivorus Coccophagus lecanii, Smith (Revis. p. 33), 

 Rhopus [Acerophagus) coccois,^¥i. A. Smith (North. Amer. Entom. 



1880, p. 84), have been recorded from this species. [For refer- 

 ence to this species' association with ants, cf. Ent. Month. Mag., 

 May, 1892, pp. 60 et 307, and 1894, p. 87.] 



79. RiPERSIA. 



Two Chalcids, one belonging to the genus Cerchysius and the 

 other to an apparently new genus, not far from the curious 

 hemipterous Dinocarsis, Forst, have been bred from this genus 

 by Newstead (Mon. Brit. Coccid. i. 32). 



80. Eriococcus azaleae, Comst.* 

 Howard records his Coccophagus immacidatus (Report Ent. 



1881, p. 358) from this species. 



81. Eriococcus rhodomyrti, Green.* 

 Encyrtus (Adelcncyrtus) solidus. How. (Proc. U. S. Nat. Mus. 

 1896, p. 638) is given as bred from this host by Howard and 

 Ashmead (1900, p. 402), in Ceylon. 



82. Coccus. 



I have been enabled to refer all the species of Coccus {sensu 



lato) from which Hymenoptera have been bred to their restricted 



genera, except the following four kinds, some of which are 



probably synonymous with others already cited. This method
