NATURAL ENEMIES. 
Secodella sp.—A few specimens of a very beautiful, large, 
blue chalcid were reared in the winter of 1913 and occurred in 
much greater numbers the following year. A larva differing 
from those usually found in the Juniper berries was discovered 
in December, 1914, among the large particles of excrement 
characteristic of the Tineid larve; hence, I assumed that it 
was parasitic on the Tineid. After placing a few in vials, the 
large blue chalcid bred out, the females of which are long and 
possess a tapering abdomen. This whole subfamily are external 
feeders on Lepidopterous larve. Mr. Crawford of the U. S. 
National Museum has just informed me that this is a new 
species, and belongs to the genus Secodella. 
Larva—-Length 2.2 mm. General color dull white, with the middle 
segments brownish (Fig. 6, Pl. XV). Head distinct, with a tubercle on 
its dorsal surface (Fig. 7, Pl. XV). Antennal tubercles whitish and very 
prominent. Two tiny, pointed mandibles. In some specimens, the 
spiracles and tracheal system are visible. Prothorax provided with 
four minute spines while the other segments apparently do not have any. 
Family Encyrtide.—On October 17, I dissected out of the 
caterpillars six parasitic larvae which were greenish in color and 
about 1.8 mm. long. The host larva was apparently healthy 
and crawled around naturally, although a small swelling was 
visible on one of the abdominal segments. It seems that only 
about three of the parasites mature in one host larva—the 
pupe of these arranging themselves 1n a peculiar manner. The 
host larval skin is pushed in, in two places so that the outlines of 
three pupe are visible, the anterior one having the head and legs 
of the host attached to it (Fig. 4, Pl. XVII). The adult isa 
pretty chalcid, the male having beautifully branched antennze 
(Fig. 1, Pl. XV). According to Ashmead’s table, this species 
runs down to the genus Prionomitus (?). I reserve the descrip- 
tion of these parasites for a later date. 
Protapantales sp.—A few parasites belonging to this genus, 
as determined by Professor Bradley, were reared. The adults 
were observed ovipositing on June 11, while the eggs of 
Arygyresthia were still attached to the berries, hatching at this 
time. Just before ovipositing, the abdomen is extended and 
the hind legs are rubbed against each other and over the 
ovipositor.
