HYMENOPTEROUS PARASITES OF COCCID. 955 
1. ASPIDIOTUS. 
From unidentified members of this genus Howard (‘ Revision 
of the Apheline of North America,’ 1895, p. 21) bred Perissop- 
terus pulchellus, and (lib. cit. p. 42) Ablerus clisiocampe, Ashm., 
which latter had been originally raised from a Lepidopteron. 
Dalla Torre says that Aphelinus annulicornis, Ratz., has also 
been bred from this genus, though Ratzeburg (Ichn. d. Forst. 
ill. 195) simply gives it as preying upon some ‘‘ Coccus.”’ 
2. Aspidiotus perniciosus, Comst.* 
Howard (loc. cit. 27) tells us that Aphelinus fuscipennis preys 
on this species, and Ashmead also represents Rhopoideus citrinus, 
How., as destroying it in California. 
3. Aspidiotus ancylus, Putn.* 
Both Prospalta aurantit and Physcus varticornis are named 
by Howard (l. c. 41 et 48) from specimens bred from this species. 
4. Aspidiotus abietis, Schr.* 
Many males and one female of Coccobius circumscriptus, 
Ratzeburg, were bred by him (ichn. d. Forst. 111. 195) from 
Coccus pini, together with his C. luteus and single male C. incon- 
spicuus (l.c. 196 et 210). Aspidiotus pint, Comst., is given as 
the host of Prospalta aurantit, How. (Revis. 41), and by Gaulle 
(Cat. Hym. France, 106) of Aphelinus agriope, Walk. 
5. Aspidiotus ostreeformis, Curt. 
The synonymous A. tili@, Bché., is said by Ratzeburg (J. c. ii. 
148, iii. 189 et 192) to have produced Hncyrtus dendripennis and 
E. hirsutus, very possibly also E. longicornis; the first is now 
synonymised with Habrolepis zetterstedtii, Westw., and the last 
with Hricydnus longicornis, Dalm. Gaulle (Cat. 106) adds 
Azotus marchali, How., and Archenomus bicolor, How., to its 
parasites, and Ashmead (p. 409) says the cosmopolitan Arrheno- 
phagus chionaspidis, Aur., attacks Diaspis ostreeformis, Sign. 
6. Aspidiotus hedere, Vall. 
This is destroyed by Prospalta aurantii, Howard (Revis. 41), 
and, under its better-known name, A. nerit, Behé., Tyler Towns- 
end bred four examples of Signiphora aspidiotii, Ashm. (p. 412) 
from it in Mexico in November, 1894; Ashmead gives (p. 411) 
his S. mexicana and (p. 409) Arrhenophagus chionopsidis, Aur., 
as attacking it, and Gaulle (Cat. 106) Aspidiotiphagus citrinus, 
Crawf. 
7. Aspidiotus uve, Comst.* 
Howard describes (‘ Insect Life,’ 1894, p. 6) his Prospalta 
murtfeldtii from this species.
