HYMENOPTEROUS PARASITES OF COCCID2. 277 
attack C. pinifolit, ?Baron; while in Europe Prospalta aurantii, 
How., is said by Dalla Torre (Cat. v.) to have been bred from 
Leucaspis pinifolie. 
24. Chionaspis furfurus, Fitch.* 
Ablerus clisiocampe, Ashm., originally bred from Bombyces, 
is said to prey upon this species by Howard (Revis. p. 42). 
25. Chionaspis euonymi, 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 varticornis, How, 
(Revis. p. 438). 
28. Chionaspis permutans, Green.* 
Aphelinus mytilaspidis, Baron, is the only parasite known 
from this host (Howard, Revis. p. 25). 
29. Chionaspis eugenie, Mask.* 
The cosmopolitan Arrhenophagus chionaspidis, Aur., is re- 
corded hence by Ashmead (1900, p. 409). 
30. Myrimaspis. 
From an unnamed species of this genus on Salix Howard 
records (Revis. p. 26) Aphelinus abnormis, and from another 
specimen of the same genus (/.c.) his A. diaspidis was bred. 
31. Mytilaspis pomorum, Bché. 
Several parasites have been described from this destructive 
species in America: Aphelinus abnormis (How., Revis. p. 26), 
A. fuscipennis (l. ¢c. p. 27), A. mytaspidis (l.¢. 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 beckii, Newm.* 
From Aspidiotus citricola, Pack., Ashmead (‘Orange Insects,’ 
1880, p. 81) gives Signiphora flavopalliata ; Howard adds Pros- 
palta aurantit (Revis. p. 41), Aphycus flavus (Report Ent. U.S. 
Dept. Agric. 1881, p. 865), from the West Indies ; and his Signi- 
phora flavopalliata is said to also prey upon it by Ashm. (p. 411).
