HYMENOPTEROUS PARASITES OF COCCID.E. 277 



attack C. pinifolii, ?Baron; while in Europe Prospalta aurantii, 

 How., is said by Dalla Torre (Cat. v.) to have been bred from 

 Leucaspis pinifolia. 



24. Chionaspis furfiirus, Fitch.* 



Ahlerus clisiocampa, Ashm., originally bred from Bombyces, 

 is said to prey upon this species by Howard (Revis. p. 42). 



25. Chionaspis eiionymi, Comst.* 



In the same paper (p. 27) Aphelinus fuscipennis, How., is 

 recorded hence. 



26. Chionaspis quercus, Comst.* 27. C. americana, John.* 

 Both these species are attacked by Physcus variicornis, How. 

 (Eevis. p. 43). 



28. Chionaspis permutans, Green.* 

 Aphelinus mi/tilasjyidis, Baron, is the only parasite known 

 from this host (Howard, Revis. p. 25). 



29. Chionaspis eugenice, Mask.* 

 The cosmopolitan Arrhenophagus chionaspidis, Aur., is re- 

 corded hence by Ashmead (1900, p. 409). 



30. Mytilaspis. 

 From an unnamed species of this genus on Salix Howard 

 records (Revis. p. 26) Aphelinus ahnormis, and from another 

 specimen of the same genus {I.e.) his A. diaspidis was bred. 



31. Mytilaspis pomorum, Bch6. 



Several parasites have been described from this destructive 

 species in America: Aphelinus ahnormis (How., Revis. p. 26), 

 A. fuscipennis {I. c. p. 27), A. mytaspidis (I. c. p. 25), Chiloneurus 

 diaspidinarum, How. ('Insect Life,' 1894, p. 256), and the 

 Proctotrypid, Anaphes gracilis, How. (Report Ent. U. S. Dept. 

 Agric. 1881, p. 370). 



32. Mytilaspis gloverii, Pack.* 



Ashmead assigns his Floridan Signiphora flavopalliata (1900, 

 p. 411) to this species, and Aphelinus fuscipennis is also recorded 

 from it by Howard (Revis. p. 27). 



33. Mytilaspis becJdi, Newm.* 



From Aspidiotus citricola, Pack., Ashmead ('Orange Insects,' 

 1880, p. 31) gives Signiphora flavopalliata ; Howard adds Pros- 

 palta aurantii (Revis. p. 41), Aphycus Havus (Report Ent. U. S. 

 Dept. Agric. 1881, p. 365), from the West Indies ; and hi^ Signi- 

 phora flavopalliata is said to also prey upon it by Ashm. (p. 411).
