allow the passage of the largest eggs.
There are nowhere the so-called com-
partments for nutrition ; each egg fol-
lows the other, but the ripe ones are
connected by darker funiculi, containing epithelial cells, and around them rounded cells with a nucleus. The interior
membrane of the egg tubes is structure-
less and h-yaline, not very easily seen. The exterior membrane is fibrous, and
around the larger eggs shows often
lacunes and holes filled with epithelial cells with nuclei, The connecting parts
around the lacunes are often small and
of decided muscular appearance. In the
part between two eggs the membrane is
striated longitudinally.
The chorion of ripe eggs in the tubes
shows sexangular spaces, the borders be- tween them comparatively wide and
hyaline.
The centre of these spaces are
darker and filled with pavement cells,
round, of .015 mm. in diameter, with
numerous fine dark spots.
I was not able to find the micropyle
in egg5 contained in the ovarium.
The
micropyle of laid eggs is dorsal a little before the inferior pole ; there are ten to twelve little holes somewhat different in situ, forming small funnels with a stem
as long as the diameter of the holes.
Near them numerous filiform sperma-
tozoa (?) were seen. The eggs are
cylindrical, concave on one side, the
ends rounded a little; often one end
thicker ; the yolk corpuscula .OI~ to .025 mm. in thickness.
The dissected queens of E. rippertiz'
were from Jamaica and Cuba, of T. gil-
vusfrom Rangoon, Burmah. 23, ri$-
pertii is probably the long sought for
imago of Termes devastans, Kollar.
The above is a part of a proposed mono-
graph of the anatomy of the termitina
for which a large number of figures have been made.
SECOND CONTRIBUTION TO A KNOWLEDGE OF THE AUTUMN LIFE-HISTORY OF CERTAIN LITTLE KNOWN
APHIDIDAE.*
BY CLARENCE MOORES WEED, COLUMBUS, OHIO. The present paper is the result of a
continuation of the study of the autumn
life-history of the ajhididae, begun in
Illinois in 1887. The observations
here recorded were made at Calumbus,
Ohio, during the autumn of 1888, upon
the grounds connected with the Ohio
State University.
MELANOXANTHUS SALICTI (HARRIS).
This species was first described by
Dr. Harris in his treatise on insects
injurious to vegetation as Aphis
salicti* In the Flint edition of the
Treatise, however, Mr. Uhler states
in a foot-note that the specific name
had been ^long ago appropriated by

Schrank to a very different species of
Aphis inhabiting Europe," and suggests
that the American species "might be
called Aphis salicicola ."
The insect was again briefly discussed
as Lachnus salicicola by Dr. Cyrus
Thomas in 1878,* and finally in his
Synopsis of the aphididae of Minne-
sota,? Professor 0. W. Oestland refers
the species to Melanoxanthus and
restores the name originally given by
Harris, which, he says, "is not occu-
pied when applied to this genus."
The only forms of the species as yet
described are the viviparous ones.
My observations upon the insect
+began in October, 1888, when I found
it very abundant on the twigs of a
species of willow (Salix) growing in
the bottoms of the Olentangy river on'
the Ohio State University farm. The
sexed forms were present in great
abundance and could be seen mating,
while many of the females were busily
engaged in oviposition. The following
descriptions were drawn up from living
specimens.

wings . . . . . 7.50 mm.

cous bloom. Legs very long, hairy;

joints 111 to VII roughened with numer-
ous sensoria ; cornicles vasiform. Pro-
thorax with a blunt tubercle on each
side. Wings hyaline ; veins brown-
ish ; wing insertions generally greenish black.

taken on twigs Salix sp., 29 October
1888. Some of them seen in copula
with oviparous females.

tion of tibiae together with tarsi black.. Antennae hairy; joints I and I1 uni-
coloro~ls with body, proxima of 111

4!Cg. ly incrassate. Antennae about + longer Length I .oo mm., oval, greenish at
first but becoming black in a short time. Deposited on bark of twigs, especially
about buds.
Notwithstanding the abundance and
destructiveness of this species, its life- history does not seem to have been
-traced, nor the sexed forms described.
During the past season I observed the
habits of the species which was abun-
dant on the currant bushes in my gar-
.den, finding that the lice left the bushes <early in summer but was unable to
learn to what plant they migrated.
In
September winged viviparous females
returned to the currants and 'gave birth to young which developed into ovipar-
ous females. The winged males flew
in from some other plants, presumably
Toeing developed on the same plant as
the migrating viviparous females which
gave birth to the oviparous form.
Wi* male.
Length of body . . , 2.00 mm.
' " antennae . . 2.70 mm.
' " cornicles . . 0. 50 mm.
Wing expanse . . . . 8.50 mm.
Antennae, head, band on dorsum of
prothorax, row of dots on each side of
dorsum of abdomen, and transverse
patch back of middle of same, black.
Legs very long, with coxae, apical half
of femora, and apical fourth of tibiae,
together with tarsi, black, the rest being yellow. Cornicles long, slender, slight- than body, slender, roughened with
numerous sensoria ; joint I large, thick- ened, about as long as I1 ; I11 longer
than any except VII; IV and V sub-
equal ; VI shorter than V ; VII very
long and slender. Cauda minutely
tuberculate, with several curved stiff
hairs arising from the margin.
Described from several specimens
taken on under surface of cultivated
currant leaves, 3 I October, 1888.
Oviparous female.
Length . . . .7j mm. to 1.00 mm.
Body globose ; greenish, shade vary-
ing with age of specimen.
Antennae
pale at base but blackish apically, and
at articulations. Legs pale, articula-
lations and tarsi dusky ; the thickened
posterior tibiae greenish brown. An-
tennae short, less than half the length
of the body : 6-jointed ; joints I and I1 short, subequal ; I11 and VI subequal,
both longer than any of others ; IV and
V subequal, each about + shorter than
I11 ; joints I11 to VI strongly tubercu- late, having numerous sensoria. Cauda
long and large, spinosely tuberculate,
with several long curved hairs arising
from its dorsal surface. Rostrum reach-
ing posterior margin of second coxae.
Described from many specimens
taken on under surface of leaves of
cultivated currant, 3 I October, I 888.
In some specimens two large eggs
were plainly visible. I did not find the eggs in situ but there is little doubt
that they are deposited on the twigs,
especially about the buds.
