Male—Length 1.6 to 2.1mm.; abdomen 0.7 to 0.9mm. Similar to 
the female in coloration but much more variable, so that some specimens 
are nearly all red, all gradations being found. Pedicel and scape brown- 
ish, the latter markedly dilated above. In the darker forms, only the 
proximal portion of the scape is brownish; rest of antenna dusky. 
Wing veins brownish or yellowish. The first funicle joint slightly longer 
than the second, the rest subequal and arched above. Petiole and hind 
coxee finely reticulate, the latter about three-fourths the length of the 
former. Sometimes a brownish spot is present in the darker forms on 
the upper angle of the prothorax. 
Variety Crosbyi.— @ similar to the above in coloration and size. The 
dorsal surface of the abdomen is evenly curved, and not as straight as 
in E. juntperinus. The posterior margins of segments 2 and 3 are nearly 
parallel, while the posterior margin of the 4 segment meets that of the 
3 on the ventral surface. The tip of the abdomen appears to be rather 
sharp-pointed. The anterior border of the segments of the abdomen 
with a fine sculpture, that does not fade out on the dorsal surface. 
Viewed from above all the segments are not visible due to the greater 
curvature. This form may be a distinct species, and as I intend to work 
on this genus, further consideration will be given it at a later date. 
Described from numerous specimens reared from the berries 
of Juniperus virginiana at Ithaca, New York. 
Cotypes deposited in the entomological collection of Cornell 
University, and in the author’s collection, University of 
Minnesota. 
Larva.—(Fig. 1, Pl. XIV). Length about 2.3mm. Color dull white, 
mandibles (Fig. 3, Pl. XIV), brownish with a large, sharp tooth in its 
inner edge. Head and antennal tubercles distinct (Fig. 2, Pl. XIV). Just 
back of the mandibles is a thick, fleshy labium, slightly lobed and 
extending beyond the mandibles. On the under side of the labium there 
is a minute spine, which is elevated on a small tubercle. The setz on 
the head and thorax are medium in size, spine-like, and arise from small 
tubercles, there being eight on the head, ten on each thoracic segment 
and four shorter ones on each of the abdominal segments. On the 
mid-dorsal line of each abdominal segment is a large, rounded tubercle, 
more distinct when the larva is killed in hot water. The spiracles are 
nine in number, as shown on the diagram, (Fig. 4, Pl. XIV), there being 
one on the meso- and metathorax;, and one on each of the first seven 
abdominal segments. 
On January 10 some of the Jarve were placed in vials on 
cotton, to check up the adult stage. Similarly, five different 
kinds of larvae were taken out of the berry and checked up 
with the adult forms. The larve of E. juniperinus, when taken 
indoors, will pupate in about ten days, gradually turn black, and 
emerge about four days later.
