an egg was found in the central burrow of the mites, as shown 
in the diagram (Fig. 6, b, Pl. XVII). The egg was removed to 
note the length of the egg stage, and after two days of warm 
weather, the embryo could be seen to be already formed. The 
head was located on that end where the long pedicel arises from 
the egg (Fig. 7, Pl. XII), thus agreeing with Triggerson’s 
observations with respect to the orientation of the embryo in 
the egg (Triggerson, 1914). The mandibles could be seen to be 
working back and forth in a lively manner, while in the caudal 
half of the egg could be seen in motion, some oil globules. The 
neck of the egg was shrunken while the pedicel was curled back 
over the body of the egg. These larve are quite abundant in 
the mite-infested berries, two or three being often found. They 
are comparatively active, move about, and devour large portions 
of the berry (Fig. 5, a, Pl. XVIII). 
Female.—Length 2 to 2.3 mm.; thorax 0.7 to 0.8 mm.; abdomen 
1 to 1.3mm. General color black (Fig. 1, Pl. XIII); scape and part of 
pedicel brownish, rest of antennz black. Color of legs variable; hind 
coxee, femora except knees, and tips of tarsi, black; rest of legs suffused 
with brownish. Head seen from above transverse, concave behind and 
convex in front. From the base of the antenne to clypeus there is a 
low smooth elevation. Antennal furrows with the sides straight or 
slightly convergent below. Head and thorax umbilicate-punctate; 
propodeum coarsely rugose on the sides, the longitudinal median 
depression broad and shallow, densely and distinctly reticulate-punctate 
throughout, except sometimes for the longitudinal furrow which is 
crossed with small transverse ridges. The anterior portion of the 
propodeum contains three longitudinal carinz enclosing a smooth 
quadrilateral area. On the cephalic face of the front coxe there is a 
deep diagonal furrow bounded in front by a distinct ridge, which makes 
a sharp turn near the upper angle. Wings hyaline. 
Abdomen conic-ovate, smooth, about three-fourths as wide as long, 
with a fine sculpture on the anterior half of the segments but fading out 
on the dorsal surface. Hind margins of segments 2, 3, and 4 nearly 
parallel (Fig. 3, Pl. XIII). Viewed from the side the dorsal surface of 
the abdomen presents a nearly straight line, except at the ends. Seg- 
ments 2, 3, and 4 subequal; the 5 longer than the 3 and 4 together; 7 
a little longer than or subequal with the 6. The 6, 7, and tip of sheaths 
of ovipositor clothed with fine white pile. 
Many of the cotypes vary in having more brown on the 
face, the venter of the prothorax and part of the mesothorax, 
the abdomen beneath, and legs.
