from its anterior surface an extra branch of six joints. 
The first joint of this antenna is much stouter than 
the corresponding joint on the left side. The .second 
about half as long as the first and as stout. The 
outer half of the anterior border is flattened to receive 
the first joint of the abnormal branch. From its end 
arises the regular branch of nine joints, all of which 
are normal except the first which gives off near the 
middle of its posterior border a slender spine-like 
process, half as long as the joint itself, curving out- 
ward and backward. The abnormal branch which is 
composed of six joints is directed forward and out- 
ward. The first three joints are flattened and very 
wide proportionately, the last three cylindrical. The 
first joint is about as long as the one which bears it 
and at its base about half as wide as long but consid- 
erably wider at tip. The next joint is a little nar- 
rower than the tip of the first. Its length about 
equals its width. The third is one-third narrower 
than the second and almost twice as long as wide. In 
the figure it is represented as folded upon itself. The 
fourth joint is somewhat longer than the third and 
half as wide, almost twice as long as the fifth which 
bears the sixth a long slender joint which curves in- 
ward and is as long as the fourth and fifth together. 
PRIONUS CALIFORNICUS, Motsch. 
Fig. 12 represents in a specimen of Prionus cali- 
fornicus one of the most remarkable monstrosities that 
has probably ever occurred among Coleoptera — 
remarkable not only for extent but also for symmetry. 
The left maxillary palpus bears two terminal joints. 
In the right maxillary and the left labial palpi the 
terminal joint is bifid. Each femur bears two tibiae 
furnished with tarsi and claws. The second joint of 
the left maxillary palpus appears to be composed of 
two joints closely connate, the anterior one much 
shorter than the other, each bearing a terminal joint 
of somewhat unequal lengths, as shown by fig. 12 a. 
The terminal joint of the right maxillary palpus is 
deeply cleft at apex representing two joints connate 
at their basal halves; fig. 12b. The terminal joint 
of the left labial palpus gives off anteriorly from its 
base a second joint half as long and as stout as the 
other and connate with it ; fig. 12c. The antennse 
are normal. The anterior femora are normal in 
length and in articulation with their coxae. They 
gradually widen from base to apex where they are 
more than twice as wide as a normal femur. Rhom- 
boidal in section; the superior surface about one- 
third narrower than the inferior. The apices are 
dilated and deeply notched vertically, making two 
processes about as long as wide, each containing a 
normal cotyloid cavity with which the tibiae are articu- 
lated in a normal manner. Fig. i2d, shows the 
femur and articulations as seen at the end. Of the 
tibiae the anterior is somewhat shorter and about two- 
thirds as stout as the posterior, which is probably the 
normal one. The spurs, tarsi, and claws of both are 
similar. The middle femora are normal in length 
and form but about one-half stouter. The apices 
each contain one large cotyloid cavity. Into this, 
which is twice as wide as a normal one, is inserted a 
single broad condyle formed by coalescence of the 
condyles of the two tibiae is shown in fig. i2e. The 
anterior of these is somewhat shorter and about two- 
thirds as stout as the posterior. Its tarsi are more 
slender and a little shorter. The articulation of the 
tibiae with the left posterior femur is identical with 
that of the middle femora; fig. i2e. The anterior 
of the two tibiae and its tarsus are about five-sixths 
the length of the posterior and one-half more slender. 
In the right posterior femur the articulation with the 
two tibiae differs from all the others. The femur it- 
self is about equal in thickness to the left but is a 
trifle more dilated at apex. This is not notched as 
in the anterior femora, but truncate. Each tibia is in- 
serted into a distinct cotyloid cavity separated by a 
considerable interval; fig. i2f. The anterior of the 
two has been unfortunately broken off about one- 
fourth of an inch from the femur. The structure of 
the under side presents no departure from the normal 
standard.

ELEODES PILOSA, Horn. 
In fig. 13 is shown a specimen of Eleodes pilosa , 
the right antenna of which is deformed ; the ninth 
joint bearing on its end two branches of two joints 
each. Fig. 13a, represents the antenna enlarged. 
The first seven joints are normal. The eighth and 
ninth equal each other in length, being slightly shorter 
than the seventh. The eighth is as wide as long. The 
ninth at base is as wide as long ; at the middle almost 
twice as wide. From the anterior part of the end 
arises a branch of two joints which are flattened, 
almost connate and a little more than half as wide as 
the ninth joint and as long as wide. The last joint is 
sinuate at tip. From the posterior part of the end of 
the ninth joint arises a branch also of two joints 
which equal in length those of the other branch but 
are more cylindrical and more nearly resembling nor- 
mal terminal joints.

HELOPS SULCIPENNIS, Lee. 
Fig. 14 represents an anomaly in the right maxillary 
palpus of a specimen of Helops sulcipennis. Fig. 14a, 
shows the normal palpus. The anomaly consists in 
the second joint bearing two terminal joints, one from 
the outer end of the anterior border and one from the 
tip. The first joint of this palpus is normal. The 
second nearly so excepting a dilation and flattening 
of the anterior border into which the terminal joint 
is inserted. The latter joint, which in the figure is 
represented as seen from below, is foreshortened as 
its plane is nearly perpendicular to the plane of the 
palpus proper. When viewed from the side it is pre- 
cisely similar to the terminal joint in fig. 12a. The 
other joint which arises from the tip of the second is 
really made up of two joints soldered together at the 
bases of their broad surfaces. It is consequently 
twice the thickness of the other terminal joint and at 
its free edge deeply grooved indicating the union of 
two joints, and presenting that silky appearance com- 
mon to the free edge of the normal joint. It is 
shown in the figure as seen partially from below, par- 
tially from the side. The parts shaded are intended 
to represent the edges of the two joints in one, the 
dotted part the deep groove.
