INTRODUCTION.

We have published, from time to time, in the Proceedings
of the Natural History Society of Wisconsin, papers which in-
cluded descriptions of Attidee from Central America and Mexico.
These papers are: “The Sub-Family Lyssomane,” “The Ant-
like Attide,”’ “The Marptusa Group,” “The Homalattus
Group,” and two short papers on “ Attidee from Guatemala.”
Our paper on North American Attidee also contains a few Mex-
ican species. In the following paper we give a number of new
genera and species from the same region, the material for
which has come to us from various sources. Several small col-
lections have been sent to us by our correspondents; the late
Count Keyserling sent us, at different times, a number of
species, mostly from Panama; and a large part of our collec-
tion we made ourselves in Guatemala and Honduras.

The artificial key which accompanies this work includes
all the species from Central America and Mexico that are
known to us, the old as well as the new. It is designed to les-
sen, somewhat, the difficulty of determining species, but we
ourselves, consider it only a partial solution of the problem.

Including this paper there have now been described about
one hundred species from Central America and Mexico. A
more thorough investigation of these regions will doubtless
bring to light at least one hundred more, and consequently
any generalizations upon geographical distribution would be
scarcely satisfactory. Of the forty-three genera thus far de-
scribed only thirteen are found in the United States.

The drawings for the genus Parnexnus and some of
those for Dendrypkantes and Habrocestum were made by Miss
Lydia Hart. All of the others were made by Mr. J. H. Emer-
ton.

The measurements are given in millimeters.

AMYCUS (c. KocH).

The cephalothorax is from moderately high to very high.
It is much higher in the males than in the females. ‘The
thoracic part is wider than the cephalic, the outline usually
being rounded. The sides round off from the high cephalic
plate both behind and on the sides. The quadrangle of the
eyes is equally wide in front and behind or wider in front; it
is one-fourth wider than long and occupies about one-half of
the cephalothorax—oftener more than less. The first row is
straight or somewhat curved, with the middle eyes large (two
or three times as large as the lateral), and projecting, especially
in the males, in which sex, moreover, the clypeus is very high,
often higher than the large eyes. The second row is nearer
the first than the third. The third row is narrower than the
cephalothorax at that place.

We use Amycus rufifrons, E. Simon, as typical of this genus,
since we have no example of C. Koch’s type, spectabilis. (PI. I,
figs. 1-Ic.)

Our genus Titanattus is very close to Amycus, differing
only in the square look of the cephalic plate, from which the
sides and posterior part drop almost vertically, and in the very
strong curve of the first row of eyes. The relative length of the
legs of the males in Amycus, so far as we know, is 3142 or 1342,
while in our only species of Titanattus it is 1423. Titanattus
sevus was described in Proc. Nat. Hist. Society of Wisconsin,
December, 1885.

In “Die Arachniden_Australiens,’ Dr. L. Koch describes

_several species of Attidee which he places in the genus Amycus.
In referring to these species Dr. Thorell, in “ Studi sui Ragni
Malesi e Papuani,” III., p. 467, says, that they belong in the
genus Mexvia C. K. Now C. Koch’s type for the genus Mevia
was pencillata, which is a synonym of Attus niger, Hentz, one
of the commonest of our native species,and one with charac-
teristics so different from the Australian species under discus-
sion that it would be out of the question to place them in the
same genus. We have no specimens of Dr. L. Koch’s species,

18 PECKHAM. [Vol. 3.

but the figures given certainly bear a strong resemblance to
Amycus. At any rate, whatever else they may be, they cannot
be Maia.

- The quadrangle of the eyes is wider in front than behind,
is one-fourth wider than long, and occupies more than half of
the cephalothorax. The anterior eyes are a little separated
from each other and form a straight row, the middle being just
twice as large as the lateral. ‘The second row is nearer the first
than the third. In the male the clypeus is plainly wider than
the large middle eyes, and is divided into two sections by a line
which marks off the lower third from the upper part. ‘The
falces are short, broad, vertical and parallel. In the female the
clypeus is not quite so high as the large eyes and the falces are
a little inclined backward.

There is a good deal of variety in the coloring of the
males. The cephalothorax is dark brown on the sides and
behind. ‘There is a central white spot on the thoracic part.
Some specimens have the cephalic plate covered with brilliant
red hairs, excepting a white central line, while all the eyes are
surrounded by circles of short brilliant red hairs, and a ridge
of long upright red hairs stands up above the first row of eyes.
In others the color of the hairs is dull brownish red, while in
one example there is no red at all, all of the hairs, the ridge as
well as the shorter ones, being pure white. The abdomen is
yellow or pale brown in the middle region with a scalloped
dark band on each side. In the clear central space there are
two pairsof dark dots on the posterior part and one pair in

No. 1.] ATTIDA’ OF CENTRAL AMERICA. 19

front of the middle. This central part and the lower sides
seem to have been originally covered with white hairs. Low
down across the front end of the abdomen is a narrow dark
band, and above this there is a curved white band. The first
and second legs of the male are usually darkened, excepting the
proximal end of the femoral joints; these, with the other legs
and the palpi, are of a light yellowish color. One male, from
Guatemala, is much darker than the others.

The females are much like the males, although the color is
decidedly lighter. Some of them have red and some white
hairs on the cephalothorax, but none of them have the upright
ridge over the eyes. ‘The abdomen has a white line down the
middle, and has the inner edges of the dark wavy bands edged
with white dashes and spots.

This species was described as Triptolemus benignus in Pro-
ceedings of the Nat. Hist. Society of Wisconsin, December,
1885.

We have three males and five females from Panama, and
one male from Gautemala, near Ysobol.

The quadrangle of the eyes occupies more than one-half

The middle eyes of the first row are more than twice as large as
the lateral eyes. The first row is plainly curved. ‘The second
row is nearer the first than the third. The third row is nar-
rower than the cephalothorax. The clypeus is somewhat
higher than the large middle eyes. The falces project a little.
They are long and slightly divergent, with a tooth on the inner
side near the distal end. The fang is short. The palpus is as
long as the femur, patella and tibia of the first leg, having its
own tibia a little longer than the tarsus, while the patella is

nearly as long as the tibia and tarsus together. There isa
strong apophysis at the distal end of the tibia, on the outer
side,

When dry, the cephalothorax, legs and falces are brown.
The eyes are placed on black spots, which, however, are nearly
covered with white hairs, patches of which are also seen on the
eye-region and in the post-ocular depression. Around the two
middle anterior eyes are rings of brilliant red hairs, which
grow longer, in the form of tufts, in the spaces above and
between the middle and lateral eyes. The abdomen is pale
brown, with a brilliant white band down the middle, on either
side of which, at the posterior end, are three black spots in a
longitudinal row. On each side of the abdomen are three
oblique white bands, the posterior two being low down. The
palpusis white (without hairs) throughout its length, only the
bulb of the tarsus being darkened.

We have asingle male, from the eastern part of Gautemala,
which was first described in 1885, in a paper on Gautemala
Attide in the Proceedings of the Natural History Society of
Wisconsin. It is redescribed here with more detail because we
have since received several other species which resemble it
so closely that it is difficult to distinguish them.

This species is of about the same size and coloring as longi-
palpus, and also resembles it in having a long white palpus.
It differs, however, in the higher clypeus, the larger middle
eyes, the vertical falces and in some smaller details.

The quadrangle of the eyes occupies more than one-half of
the cephalothorax, and is nearly equally wide in front and
behind. The middle eyes of the first row are about three times

as large as the lateral. The clypeus is excessively high—
plainly higher than the large middle eyes. The first row of
eyes is plainly curved. ‘The second row is nearer the first than
the third. The falces are long vertical and parallel, with a
strong pointed tooth at the end on the inner corner. The fang
is strong and rather long. The palpus is not quite so long as
the femur patella and tibia of the first leg. Its tibia is a little
shorter than the tarsus and these two joints together are longer
than the patella. Like longi-palpus, it has an apophysis at the
end of the tibia.

The cephalothorax and legs are yellowish brown, the coxee
and the proximal ends of the femoral joints lighter than the
rest. ‘The anterior eyes are surrounded by circles of brilliant
red hairs; just above this row, standing up stiflly, is a ridge of
long, yellowish red hairs tipped with black, and in the middle
line, just behind this ridge, isa patch of snow-white hairs. The
anterior end of the abdomen is pale. Beginning in two dark
spots in front of the middle, a brownish region runs back, on
each side, to the end. On the posterior half there is a band of
white hairs down the middle, and on either side of this are two
large black spots, while further back is a third pair of spots,
much less distinct. Although we have two specimens, both
are rubbed, but there have evidently been some transverse
bands and spots of white hairs on the anterior part of the
abdomen. The clypeus has a strong reddish tinge on the
upper half, which is also ornamented with a large central patch
of white hairs. The lower half, which overlaps the falces, is
black.

We have two males from Central America, the exact
loeality being unknown.

This species, which also has a long white palpus, is much
smaller and lighter colored than longi-palpus and pacatus.

The quadrangle of the eyes occupies more than one-half of
the cephalothorax, and is nearly equally wide in front and be-
hind. The middle eyes of the first row are a little more than
twice as large as the lateral. The clypeus in the male is much
higher than the large middle eyes; in the female it is scarcely
half as high. The first row of eyesis curved. ‘The second row
is nearer the first than the third. The falces of the male are
long, vertical, and nearly parallel, with a strong blunt tooth at
the end on the inner side. The fang is strong and rather long.

The palpus of the male has the tarsus longer than the
tibia, and the patella shorter than these two joints together.
There is an apophysis at the end of the tibia, on the outer side.
The palpus of the female is also long, white and slender.

The general color of the male is light yellow, the abdomen
being paler than the cephalothorax and legs. There are white
hairs around the anterior eyes and in large patches on the
sides of the eye-region. The clypeus seems to be in two parts,
the upper being tinged with red, while the lower is blackish.
There is a central vertical band of white hairs which reaches
from the eyes nearly to the lower edge. The abdomen has a
band of white hairs around the anterior end, another down the
middle of the posterior half, and some scattered white hairs on
the lower sides. On either side of the central white band are
two large black spots, and in one specimen there is a third pair
of less distinct spots in front of these, and a fourth pair nearer

the spinnerets, the spots of the two longitudinal rows thus
formed being connected by a brownish band.

The female is much like the male. There seem to be no
hairs on the clypeus. On the anterior part of the eye-region
are some light-colored slightly iridescent hairs with violet
reflections. If our males ever had any such hairs they have
been entirely rubbed away. The abdomen has two pairs of
large brown spots just behind the middle, each of which is
edged with white.

We have two males and one female from Panama, sent to
us by Count Keyserling.

This, the fourth species having a long white palpus, is
small and light colored, like fallax, but is ornamented, in both
sexes, with red hairs around the eyes, which are lacking in that
species.

The quadrangle of the eyes is nearly equally wide in front
and behind, and occupies more than half of the cephalothorax.
The first row is curved, but not so strongly as in the related
species. The middle eyes are plainly more than twice as large
as the lateral. The second row is nearer the first than the
third. The clypeus of the male is much lower than in fallaz,
being scarcely higher than the large middle eyes. In the
female, on the contrary, it is rather higher than in the female
of fallax, being about three-fourths as high as the large eyes.
The falces in the male are long, vertical and parallel, with a
long pointed tooth at the end, on the inner corner. In the
female they are much shorter, without any tooth.

24 PECKHAM. [Vol. 3.

In the male palpus the tarsus, taken alone, is nearly as long
as the patella, and is much longer than the tibia. The palpus,
asa whole, is shorter than in fallax. The female also has a
long slender white palpus.

The general color of the male is pale brown, the cepha-
lothorax being tinged with yellow. All of the eyes are sur-
rounded by short brilliant red hairs. The front view is very
picturesque, as there is a snowy-white tuft of hairs in the mid-
dle of the front part of the eye-region, in front and on the
sides of which are upright red hairs, while the clypeus has a
large patch of white hairs in the middle. The lower part of
the clypeus is not blackish, as in fallax, but is of a pale brown
tint, differing from the upper part, which is tinged with red.
The abdomen has a pair of round dark spots near the anterior
end, just in front of which is acurved band of white hairs. On
the posterior part are two pairs of angular dark spots, in front
of and in line with which is a pair of white spots. The dark
spots are separated by a central band of white hairs, and there
are some white hairs on the lower sides. The legs and falces
are yellowish, like the cephalothorax. G

In the female the cephalothorax and legs are of a deeper
tint than the abdomen, which is of a clear pale yellow. There
are red and white hairs around all the eyes. The clypeus is
yellow with a horizontal line of white hairs a little way below
the eyes. he anterior part of the abdomen has two dark
spots with a curved white band in front, as in the male, but
the posterior part has some figures in black which are very
variable in shape, sometimes consisting of a series of dashes and
spots and again appearing as is shown in the figure.

We have one male and three females, sent by Count Key-
serling, from Panama, fallax coming from the same locality.

In this species the cephalothorax is longer, and the sides
more nearly parallel than usual. The quadrangle of the eyes
is wider in front than behind, is one-fourth wider than long
and occupies more than one-half of the cephalothorax. The
clypeus in the male is only a little higher than the middle
eyes, which are a little more than twice as large as the lateral
eyes of the first row. ‘These four eyes are separated, and the
row is slightly curved. In the female the clypeus is about one-
third as high as the middle eyes, which are less than twice as
large as the lateral. The second row is nearer the first than
the third. _ : \

Our specimens are so much crushed and rubbed that any
correct color description is impossible. Both cephalothorax
and abdomen are dark, much darker than the legs, excepting
those of the first pair in the male. ‘The upper surface, in the -
male, has the eye-region and the anterior central part of the
thorax lighter colored than the rest, and slightly tinged with
yellowish. Above the first row of eyes is a row of long, reddish
hairs extending forward, notupward. The abdomen is brown,
with a darker line running along each side, and a pair of dark
spots at about the middle point just inside of these lines.

In the female the body is of rather a dark brown color,
while the legs are lighter with a tinge of yellow. The cepha-
lothorax has a light-colored line with diverging branches, on the
thoracic part. On the abdomen nothing is discernible except-
ing a central row of small dark chevrons on the posterior part.

We have one male and one female from the eastern part
of Guatemala.

CHAPODA, GEN. Noy.

The cephalothorax is rather high. Fromits highest point
at the dorsal eyes it slants plainly in both directions, more
markedly behind than in front; after the first half the thoracic
slope is still more abrupt. There is a large post-ocular de-
pression. In the female the sides of the cephalic part are ver-
tical, but in the male, where the cephalothorax is higher, they
widen from above below, both in cephalic and thoracic parts.
The narrowest point is at the front end, and the widest behind
the dorsal eyes. The quadrangle of the eyes is a little wider
in front than behind, is one-fifth wider than long, and occupies
about two-fifths of the cephalothorax. The anterior eyes are
large and forma plainly curved row; the middle eyes are close
together and are plainly less than twice as large as the lateral,
which are a little separated from them. The second row is
half-way between the first and the third. The third row is not
quite so wide as the cephalothorax at that place.

In general appearance, and in the enamelled surface of the
integument, this genus resembles certain species of Amycus.
The cephalothorax, however, is not so high, and the lateral
eyes of the first row are relatively larger. It is still closer to
the following genus, Helorus, but the spiders are smaller, with
the cephalothorax lower and the quadrangle of the eyes nar-
rower in proportion to its length.

thorax.

No. 1.] ATTIDA) OF CENTRAL AMERICA. 27

In the male the cephalothorax is dark brown, with a band
of white hairs low down on the sides. The cephalic plate is
edged with deep black, and has the central portion covered
with hard white scales, which are separated by little seams and
cracks. The abdomen is pale brown, with an enamelled covering
of scales, which have the same crackled appearance as in the
cephalothorax. This covering splits open on the anterior part
of the dorsum showing a smooth and slightly depressed region
between the two edges. These edges are bordered by pure
white scales, which, on the posterior part of the abdomen, form
a central band, extending to the spinnerets. This band is
sometimes marked by a dark line down the middle. The
falces are black, and are long, vertical and moderately stout.
The clypeus is two-thirds as high as the middle eyes. The legs
are brown, like the cephalothorax. :

The most characteristic thing about the male, and the one
that marks off the species at once, is the shape of the palpus.
The femur bears, above, a large rosette-like mass of white hairs,
while below it has a strong apophysis. The patella has black
hairs on each side, is narrow at the proximal end and much
widened out and flattened at the extremity, while the tibia,
which is a much shorter joint, is nearly as wide as it is long at
the end where it joins the patella, but is much narrower
towards the tarsus.

We have a second male, which is smaller than the one
described and which has all the colors much paler. In both
specimens a few white hairs on the posterior sides of the
abdomen indicate that there has been some pubescence which
has been rubbed off.

The female is much like the male. The clypeus is not
so high, the falces are yellow, and are shorter and rela-
tively stouter. The split on the anterior part of the abdomen
is narrower and the white band on the posterior part is crossed
by a second band of white scales, which has at each end, near
the outer side of the abdomen, a dark spot. In the four cor-
ners made by the crossing bands the integument is darkened.

28 PECKHAM. [Vol. 3.

The spinnerets are white, each with a delicate, black line on
the outer side. The palpi and legs are yellow, barred with
black or dark brown.

We have two males and one female from the eastern part |
of Guatemala, and one female from Chapoda, Brazil, in the
Smith Collection.

HELORUS, GEN. Nov.

The cephalothorax is high. The cephalic part is inclined
forward, and the thoracic falls in a steep slant from the dorsal
eyes. The sides usually widen out from above below, especi-
ally in the thoracic part. The widest point is at the dorsal
eyes or behind them. The width of the cephalothoraxis about
three-fourths of its length. The quadrangle of the eyes is
wider in front than behind, is from one-fourth to one-third
wider than long and occupies from two-fifths to three-fifths of
the cephalothorax. The first row of eyes is straight or curved
upward. The middle eyes are less than twice as large as the
lateral and are close together, while the lateral are usually a lit-
tle removed from them. The second row of eyes is half-way
between the first and the third or is nearer the third than the
first. The third row is usually narrower than the cephalo-
thorax at that place.

This genus at once recalls Amycus, but the cephalothorax
is not so high, and the eyes of the first row are more nearly of
a size. It is still closer to Chapoda.

Mandibularis, the type, and extensus are much more closely
allied to each other than to flavens. This species differs from the
others in the shorter cephalic part, in the bulging out of the
thoracic part far behind the dorsal eyes, in the short falces and
in the vertical sides of the cephalic part, as well as in the fact
that the palpi and the first two pairs of legs have their insertion
much further back on the cephalothorax. It might have
served as the type of a new genus, but as we had only a male
this seemed inexpedient. It agrees with the other species in
the prominent cephalic plate and in the covering of iridescent
scales on the abdomen.

In this species the cephalothorax is rounder than in
extensus. The sides widen out plainly from above below, so
that the third row of eyes is considerably narrower than the
cephalothorax at that place. The lower outline of the sides is
quite evenly curved, the widest point being a little behind the
dorsal eyes. The cephalic part is convex, but is scarcely at all
inclined. The thoracic rounds off from the dorsal eyes to the
lower margin, not being flat, as in extensus. The quadrangle of
the eyes is one-fourth wider than longand occupies a little more
than half of the cephalothorax. The anterior eyes are close
together in a slightly curved row; the middle are nearly twice
as large as the lateral, neither the lateral nor the dorsal eyes
being so large as in eatensus. The clypeus is one-fourth as high
as the middle eyes. The falces are horizontal and are very
long and strong, with a long curved fang. On the inner edge
there are three small teeth near the proximal end and two
large ones at the extremity, while underneath there is one
small tooth, not very far from the end. The fang also has a
tooth, near its insertion. The palpus is very long and has
the same crook in the femur that is seen in eatensus, the patella
and tibia, also, being at least twice as long as the tarsus. The
pedicle which joins the cephalothorax and abdomen is visible
from above. .

The falces, first legs and cephalothorax are bright reddish
brown. There are some white hairs on the sides of the cepha-
lie part and around the anterior eyes. The other legs and the
palpi are light yellow, the tarsal joint of the palpus having
some whitish hairs. The abdomen is pale brown, covered with

light-colored iridescent scales, as in eatensus and flavens. On
the back are two pairs of dark dots.

elongated, so as to be visible from above.

The cephalothorax has a very round look. The sides are
rounded out from above, below, so that the third row of eyes is
a little narrower than the cephalothorax at that place. The
cephalic part is plainly wider than the thoracic, the widest
point being at the dorsal eyes. It is inclined forward and is
very convex, while the thoracic falls in a steep flat slope from
the dorsal eyes to the posterior margin. The quadrangle of
the eyes is one-fourth wider than long and occupies about three-
fifths of the cephalothorax. The lateral eyes of the first row
are plainly more than half as large as the middle eyes and are
a little separated from them. This row is a little curved up-
ward. The dorsal eyes are large, equalling the lateral in size.
The clypeus is one-third as high as the middle eyes. The
falces vary considerably in length in different individuals.
They have a vertical part near the head, and then stretch out
horizontally, bearing a long fang. At the lower edge of the
vertical part are some small teeth. The horizontal part has,
underneath, a small tooth in the first third and a larger one
near the end. The palpus has the tarsus only half as long as
the patella and tibia together, and has a curious, elbow-lke
bend in the femur. The whole palpus is very long. The
cephalothorax and abdomen do not come together, the pedicle
which joins them being visible from above.

Different examples vary in color as well as in size, the
smaller ones being much paler than the larger. In the large
ones the cephalothorax is a bright reddish brown, with red
hairs around the eyes and on the sides of the cephalic part.
The abdomen is light brown. On the front part are two parallel
darker streaks, and behind are two pairs of large dark spots,
and, between these, a series of small dark chevrons. Around
and between the darker parts is a covering of light-colored iri-
descent hairs. The falces are bright brown, like the cephalo-
thorax. The palpi and legs are light yellowish brown, the
femur of the palpus having, where it bends, a patch of snow-
white hairs above. The first leg has the femur and the ends
of the patella and tibia bright brown, contrasting strongly with
the paler color, which hes next.

The first leg in the large variety is longer than in the
smaller one, exceeding the third leg by the length of the tarsus
and metatarsus, while in the other case it is longer by only the
tarsus.

We have seven males from Panama, in the Keyserling

In this species the sides of the cephalic part are vertical,
the third row of eyes being as wide as the cephalothorax at
that place. Behind the dorsal eyes the sides round out, quite
suddenly, to their widest point, opposite the coxze of the second
pair of legs. The quadrangle of the eyes is about one-third
wider than long, and occupies a little more than two-fifths of
the cephalothorax. The anterior eyes are all close together, in
a straight row, the middle eyes being less than twice as large as

the lateral. The clypeus is about one-third as high as the
middle eyes. The falces are moderately long and stout, and
are vertical. They are wider at the end than at the inser-
tion. The lip is as wide as long. The palpus has the tarsus
as long as the tibia and patella together.

The cephalothorax and the first pair of legs are bright
reddish brown. ‘The abdomen, the palpiand the other legs are
pale yellow. The cephalothorax has the eyes on black spots,
and seems to have been covered, on the cephalic part at least,
with yellowish white, slightly iridescent hairs. On the cepha-
lic plate, about in a line with the second row of eyes, are two
tufts of dark hairs, not always present. The abdomen has
sometimes two and sometimes four dark spots on the posterior
half. In one of our specimens it is covered with short, green-
ish yellow, iridescent hairs.

We have three males from Panama, sent to us by Count
Keyserling.

PHIDIPPUS (c. Kocu).

The cephalothorax is from moderately high to high ; it is

rounded out, especially in the male, so that it is wide in propor-
tion to its length. The widest point is behind the dorsal eyes.
The cephalic plate is inclined forward. ‘The thoracic part falls
from the dorsal eyes at first gradually, and then more steeply.
The quadrangle of the eyes is from one-third to two-thirds wider
than long ; it is much wider behind than in front, and occupies
about two-fifths of the cephalothorax. The anterior eyes usual-
ly form a curved row, the middle being less than twice as large
as the lateral and a little separated from each other, while the
lateral are separated from them by from one-third to two-thirds
of their own diameter. The second row is about twice as far
from the third as from the first row. The dorsal eyes are as
large as the lateral and form a row which is narrower than the

tion to the size of the spiders.

The genus Phidippus is represented, among our Mexican
and Central American spiders, by the three new species here
described, by Phidippus mexicanus P., N. A. Spiders of the
Family Attide, p. 23, and by P. orichalceus, C. K. (See Plate
II, figs. S-Sa, and Plate II, fig. 7.)

This genus, with its clearly marked characters and its num-
erous species, stands at the head of a large group of related genera.
This group includes Parnnus, Pardessus, Plexippus, Phileus,
Thyene, Zenodorus, Escambia, Hasarius, Dendryphantes, and many
others.

We give drawings of Phidippus morsitans as fairly typical
of the genus.

This is a large heavy hairy spider. The cephalothorax
is very dark, almost black, with long, black hairs on the eye-
region. ‘The upper surface of the abdomen is dull red, with a
covering of gray hairs; there is a wide central black band on
the posterior half, which has at its anterior end two white
spots. The dorsum is encircled by a black band, below which,
at the anterior end of the abdomen, is a white band. The
lower surface is black. The legs and palpi are of a dark red-
dish brown color, the first pair being darker than the rest, and
clothed with long black hairs. The clypeus is narrow, and is
fringed with white hairs. The falces project forward and are
short and stout; they are of a dark iridescent green color.

The lateral eyes of the first row are well separated from
the middle eyes and are scarcely more than one-half as large,
this being proportionately smaller than in georgii.

We have a single female from Central America, exact
locality unknown.

This is a very large spider, but it is not so hairy, and the
cephalothorax is not so large and massive as in carneus. The
lateral eyes of the first row are not very widely separated from
the middle eyes, and are plainly more than one-half as large.
The cephalothorax is black, with some long white and black
hairs, which stand upright all over the cephalic plate. The
integument of the abdomen is of a dark reddish brown color,
covered closely with short hairs of mixed gray and yellowish.
‘There is an indistinct darker herring-bone stripe down the
middle of the back. As the only specimen that we have is
much distended with eggs, it may be that other markings
might appear under different circumstances. The legs are all
very dark brown, thinly clothed with white hairs. The palpus
isa shade lighter than the legs, with yellowish hairs. The
falces project forward a little. They are short and stout, and
care black with a slight iridescence.

This species is close to Phidippus morsitans, but the cepha-
lothorax is longer in proportion to its width, and does not

No. 1.] ATTIDH OF CENTRAL AMERICA. 35

bulge out so widely on the sides. It lacks, too, something of
the burly look of that species, being rather more lightly and
gracefully built. |

The whole body is black. Across the cephalothorax is a
wide zig-zag white band, which is never found in morsitans,
a point running back behind each of the dorsal eyes and one
running forward between them. On the middle of the ab-
domen is a large triangular white spot, behind this is a pair of
oblique white bars, and still further back a pair of white dots;
around the front is a white band, and on the sides are two
oblique white bars, all exactly as in morsitans. The palpi are
rufus, with rather long, black hairs, whereas in morsitans the
hairs are short and of a brown color. The legs are rufus, barred
with black, like some specimens of morsitans, although in that
species they are more commonly black. In both Howardi and
morsitans the first leg has, on the inner side, long black hairs
on the femur, the tibia, and the distal part of the metatarsus,
while the patella has a long brush of snowy-white hairs. The
falces are short, stout, vertical and iridescent, but are blU®
rather than green, as in morsilans.

Phidippus mexicanus also has the three white spots on a
black abdomen, but this species is so very much larger and
hairier than Howardii, that there can be no confusion between
them.

We have a single male, sent to us from Reynosa, Mexico,
by Mr. C. H. Tyler Townsend.

PARDESSUS, GEN. Noy.

Rather large, handsome spiders, with distinct patterns.

The cephalothorax is rather high, with the upper surface
level, or slightly convex. The cephalic part is slightly in-
clined; the thoracic falls little or not at all in the anterior
half, and then slopes, not very abruptly, to the posterior margin.
The thoracic plate is bluntly narrowed behind. The sides
widen out gradually from the anterior end to the middle of
the thoracic part, and then contract a little. Thev slant out-

ward so that the cephalothorax is considerably wider below
than above. The highest point is at, or just behind, the dorsal
eyes. The quadrangle of the eyes is less than one-fourth wider
than long, is about equally wide in front and behind, and
occupies two-fifths of the cephalothorax. The four anterior
eyes are a little separated from each other, the space between
the middle eyes being narrower than that between the middle
and lateral, and form a straight row. The middle are twice as
large as the lateral. The second row is a little nearer the first
than the third row, and is narrower than the third, which is
itself plainly narrower than the cephalothorax at that place.
Of this genus we have four species, three of which were
described by C. Koch, in Die Arachniden, XIII. These are
(Plexippus) mimicus which we make the type of Pardessus,
(Plexippus) selectus, and (Phiale) gratiosus. The fourth species,
sent to us from Trinidad, by Mr. Broadway, isstill undescribed.

The clypeus is a little more than one-fourth as high as the
anterior middle eyes. The falces are vertical, and only mod-
erately long and stout, with asmall fang. At the extremity
are three small teeth, two on the upper and one on the under
edge, which are visible from the under side. The labium is short
and rounded. The maxille are obliquely truncated. The
abdomen is oval, and rather slender and graceful in form.

The cephalothorax is covered with yellowish red hairs, the
cephalic plate being darker than the rest. The abdomen is
bright orange red, with two large, black spots on the anterior
half and two wide transverse black bands behind. There is
sometimes another black band around the anterior end. The

red ground-color sometimes fades to nearly white in alcohol.
The palpi are pale yellowish, with light hairs. The legs are of
a lighter or darkerreddish color, not very hairy, but with some
pale golden scales. The color deepens, in most specimens, on
the femora, the distal halves of the tibia and the tarsi. The
falces are light or dark red, with white hairs along the inner
sides. The extremities and the fangs are blackish.

We have four females from Chapoda, Brazil, in the Smith
Collection, and a fifth from Panama, in the Keyserling Collec-

tion.
PARNAINUS, GEN. Noy.

Large, handsome spiders, with distinct markings.

The cephalothorax is high and massive. When looked at
from in front, the sides are seen to bulge out on each side of
the first row of eyes. The anterior part of the cephalic plate is
inclined forward. The thoracic part falls from the dorsal eye
to the hinder margin, the slope being more abrupt after the
first half. The lower outline of the sides is not far from circu-
lar, but there is a distinct bulge just behind the first row of
eyes where the cephalothorax is widest. They round out wide-
ly from above downward, so that, although the dorsal eyes are
on the sides of the upper surface, they form a row which is
much narrower than the cephalothorax at that place. The
quadrangle of the eyes is very shghtly wider behind than in
front. It is barely one-fourth wider than long, and occupies
nearly one-half of the cephalothorax. All the eyes are small in
proportion to the size of the spiders. The anterior row is
curved. The middle eyes are slightly separated; the lateral
are placed further back, with a distinct space between them and
the middle eyes. The middle are nearly twice as large as the
lateral. The second row is plainly nearer the first than the
third row. The dorsal eyes are fully as large as the lateral.

We found this genus upon (Phidippus) cyanidens, C. K.,
Die Arachniden, XIII, p. 156.

This genus finds its closest relations with Phidippus, Zeno-
dorus and Thyene. Zenodorus(which equals Ephippus, Thor.,and

38 PECKHAM. [Vol. 3.

is found in Australia and the Malay Archipelago), while it
bulges out in front, ike Farnznus, has the cephalothorax exces-
sively high, square-looking and massive, and has all the eyes
much larger in proportion to the size of the spiders. In Phid-
ippus the eyes are even smaller in proportion to the size of the
spiders than in Parnenus, the widest point of the cephalo-
thorax is not in front of the dorsal eyes, and the quadrangle of
the eyes is plainly wider behind than in front. In Thyene, the
spiders run smaller than in Parnznus, the cephalothorax is dif-
ferently shaped, and the lateral eyes of the first row are very
small, only half as large as the middle eyes.

The clypeus is very narrow. ‘The falces in the female are
stout and moderately long and have the anterior surface con-
vex. Inthe male they are longer and are directed obliquely
forward, with a long fang, while on the inner face is a long,
strong tooth. The sternum is long and oval. The mavxille
are long, heavy and obtusely rounded. The labium is long
and slender and pointed at the extremity.

In the male the integument of the whole body is very dark,
almost black, and three of our four specimens show patches of
scales of a most vivid iridescent green color, which, in one case,
entirely cover both cephalothorax and abdomen. In these
three specimens the falces are of an iridescent bluish green color.
In our fourth male the scales that are left on the cephalothorax
and abdomen are iridescent red and violet (the green ones
probably having been all rubbed off), and the falces are brill-
iant iridescent red with some greenish reflections. They all

have, on the cephalothorax, a wide band of white, Jow down on
each side, beginning opposite the dorsal eye and extending to:
the point at which the abdomen overlaps the cephalothorax,
and a white spot between the dorsal eyes. The one without.
the green scales has no marks nor spots on the abdomen, but.
the others have a band around the anterior part and two or
three oblique bands on each side, which are white or yellowish
white, while on the dorsum on each side of the middle, is a
longitudinal narrow velvety black band, and on these bands
are four pairs of snow-white dots. The legs and palpi are
somewhat iridescent and are almost black, excepting in one
specimen in which the palpi and the patelle are reddish
brown. ‘The first pair has a fringe of black hairs on the inner
side. Two of our three females are much lighter colored than
the males, being of a medium brown, but the cephalothorax
and abdomen have the same spots and markings that are seen
in the male, and one of them has patches of the brilliant green
scales. The falces are reddish brown above, and iridescent
green near the fang. The legs are medium brown, but the
femora are darkened and the tibia of the first is much enlarged
and dark colored, with some dark hairs on the inner side. The
third female differs from the others in being as dark as the
male, and in having the falces entirely dark red and iridescent,
with some white scales on the upper part.

We have this species from the eastern part of Guatemala,
and also in the Smith Collection from Para and the Amazon.

PHILANUS (THORELL).

Spiders above medium size.

The cephalothorax is rather high and a little longer in
proportion to its width than in Phidippus and Parnenus, having
less of the rounded appearance that distinguishes those genera.
The cephalic plate is inclined forward. The thoracic part falls
from the dorsal eyes, very gradually in the first half and then
more steeply. In the male the change from the gradual to the
steeper slope is more abrupt than in the female. The sides are

40 PECKHAM. [Vol. 3.

usually widest behind the dorsal eyes, but in some species (as
in the type) they are nearly parallel from just behind the sec-
ond row of eyes to just in front of the posterior border. They
slant outward from above downward, more widely in the male
than in the female. The quadrangle of the eyes is equally
wide in front and behind or slightly wider behind, and is from
one-fourth wider than long to nearly twice as wide as long. It
occupies a little more than one-third of the length of the cepha-
lothorax. The anterior eyes form a curved row; the middle
being less than twice as large as the lateral. They are all sepa-
rated, the lateral more widely from the middle than the mid-
dle from each other. The second row is a little nearer the first
than the third row. The third row isnot so wide as the cepha-
lothorax at that place.

While this genus is closely related to Phidippus, the shape
of the cephalothorax is somewhat different, the sides being
more nearly parallel. Moreover, the quadrangle of the eyes is
much wider behind in Phidippus. From Plexippus also it differs
in shape, as well as in haying the first row of eyes curved,
while in that genus it is straight.

The genus Philxus is represented in Mexico and Central
America not only by the species described below, but by P.
fartilis P. and P. mexicanus P., from Mexico, and by P. chrysis
Walck., from Mexico and Guatemala. ‘These three species are
described in our paper on North American Attidee, pp. 27, 28
and 30.

This spider is a little above medium size. The first legs
are long, and the falces are obliquely directed forward, and
divergent, with long fangs.

The cephalothorax is high in front. It falls gradually
from the dorsal eyes, and then a little more steeply toward the

hinder margin. The anterior eyes are rather larger than is
usual in this genus. The second row is plainly nearer the first
than the third row. The dorsal eyes are smaller than the
lateral. The quadrangle of the eyes is one-fourth wider than
long, and is a little wider behind than in front. The widest
point of the cephalothorax is just behind the dorsal eyes. The
falces are obliquely directed forward and divergent, with the
fang about as long as the rest of the falx. Their color is bright
reddish brown.

Our specimen is much rubbed. The cephalothorax is of a
reddish brown color, which is darkest on the cephalic plate.
The abdomen is of a slightly lighter brown, with a thin cover-
ing of long, dark hairs, and with patches of golden iridescent
scales. It is encircled by a snow-white band, which is broken
into spots toward the posterior end. On the dorsum are two
pairs of white spots and two pairs of abbreviated white lines, and
just at the origin of the spinnerets is a central white spot. The
legs and palpi are of a medium brown, and not very hairy.

We have one male, from Spanish Honduras.

This species is very close to Philzus chrysis, Walck., which
we have from Guatemala and from Mexico, both in shape and
in markings, but it is of a lighter color, chrysis being black,
while dutews is medium brown. Moreover, in chrysis the first
leg is relatively a little longer, exceeding the second leg by the
tarsus and the metatarsus, while in Juweus it is longer only by
the tarsus and about two-thirds of the metatarsus; and there is
a slight difference in the falces, those of chrysis having a ridge
on the front face, which is not present in luteus. In chrysis the
second leg is slightly longer than the third, while in luteus the
third is longer than the second.

ESCAMBIA, GEN. Nov.

The cephalothorax is moderately high and convex, and is
usually not much wider in one part than in another, although
some of the species (especially conspecta) broaden out a little
behind the dorsal eyes. The sides are not far from vertical,

42 PECKHAM. [Vol. 3.

widening a little from above below; in the cephalic part they
are sometimes slightly concave. The cephalic part is plainly
inclined forward. The thoracic is sometimes very slightly in-
clined backward in the first half, and sometimes rounds off more
decidedly behind the dorsal eyes. The quadrangle of the eyes
is equally wide in front and behind, or a little wider in front ;
it is about one-fourth wider than long, and occupies two-fifths,
or a little more, of the cephalothorax. The anterior eyes are
rather large, and are usually a little separated; they most
commonly form a straight or very slightly curved row, of which
the middle are nearly twice as large as the lateral. The second
row is about half-way between the first and the third. The
third row is as wide or nearly as wide as the cephalothorax at
that place. The legs are all of about the same length.

This genus presents some difficulties, as there is a good
deal of variation, not only among the different species, but
between the two sexes. The males fall more steeply than the
females behind the dorsal eyes, and have the sides more
rounded out. Among the females conspecta falls most abruptly,
in the thoracic part, and alacris next, while in parvula the fall
is very slight indeed.

Escambia bears a close resemblance to Dynamius, especially
in some of the species, as conspecta. In Dynamius, however, the
cephalothorax is flat on the upper surface for some distance
behind the dorsal eyes, and the first row of eyes is plainly
curved. :

No. 1.] ATTIDA) OF CENTRAL AMERICA. 43

In this species the cephalothorax widens out plainly behind
the dorsal eyes, especially in the male, and the thoracic part
falls in a wide and rather gradual slope in its first half, and
then more abruptly to the margin. ‘There is a distinct post-
acular depression. The anterior eyes are all separated, and
the third row is quite as wide as the cephalothorax at that
place in the female, not quite so wide in the male. The falces
are vertical and stout, and moderately long. The clypeus is
one-third as high as the middle anterior eves. The quadrangle
of the eyes is equally wide in front and behind.

The color of the cephalothorax varies from dark brown to
black. he cephalic part is iridescent, and seems to have been
covered with white scale-like hairs, although these are nearly
all rubbed off in our examples. There is a white spot on the
middle of the thoracie part, and from this two divergent white
lines appear, on some specimens, running to the dorsal eyes.
There are white bands on the lower sides. The abdomen is
brown, with a deep black band around the anterior end, and
behind this a white band, which is widest in the middle, and
has its posterior edge indented. The markings are best seen
under alcohol. The male has on the front part of the dorsum
two pairs of white spots, which sometimes join to form two
short white limes. On the middle of the back part of the dor-
sum is a band of white chevrons, more or less distinctly visible.
The female has the same pattern a little more accentuated, the
band of white chevrons being edged with black, upon which
appear two pairs of white spots, the posterior pair obliquely
elongated. These markings are very variable. The speci-
mens shown in the drawings are not very good representatives
of the species, so far -as the pattern on the abdomen is con-
cerned.

The palpus of the female has the femur and patella ight
brown, while the tibia and tarsus are black, and very stout, and
are covered with thick long black hairs, intermingled with
shorter white ones. In the male, the femur and petella have
short white hairs, and the tibia and tarsus long black ones.

44 PECKHAM. [Vol. 3.

The legs are dark brown, the first and second pairs being
the darkest. In the male the tibia and metatarsus of the first
and second legs, especially of the second, are highly iridescent,
and have, on both upper and under sides, long fringes of stiff
hairs, longer on the second leg than on the first. These fringes
are deep black on the first leg, and on the under side of the
second, while on the upper side of the second leg they shade,
through two-thirds of their length, from a light to a very dark
brown, and then have the tips pure white, making a strong
contrast. In one of our males this fringe has the pure white
edge, but is otherwise pale brown without any shading.

We have five females, and a great many males from the
eastern part of Guatemala.

In this species there is a very slight broadening of the
cephalothorax behind the dorsal eyes, which is more marked
in the male than in the female. ‘The upper surface, from the
anterior eyes through half the thoracic part, is very gently con-
vex, the highest point being at the dorsal eyes, from which the
slope forward is a little more pronounced than behind. The
final drop to the posterior margin is very abrupt but not quite
vertical. The upper surface of the thoracic part just behind
the dorsal eyes, which may be called the thoracic plate, is
crescent shaped. The sides are vertical in the cephalic part
and nearly so in the thoracic. The quadrangle of the eyes is
equally wide in front and behind, is one-fourth wider than

No. 1.] ATTIDA) OF CENTRAL AMERICA. 45

long, and occupies a little less than one-half of the cephalo-
thorax. The third row of eyes is as wide as the cephalothorax
at that place. The clypeus is one-third the height of the mid-
dle anterior eyes. he falces are vertical and moderately stout
and long, with very weak fangs.

In the female the cephalothorax is covered with yellow
hairs, excepting on the sides, where there are wide white bands.
Where the hairs are rubbed off on the cephalic region, the
integument is seen to be dark and iridescent. The abdo-
men has a blackish band low down around the anterior end
and above this a pure white band. The back is covered with
gold-colored hairs. On each side, beginning in front of the
middle, is a wide band of deep black which is crossed by two
white bars. The palpus has pure white hairs on the upper
surface of the patella, and longer, yellowish hairs on the tibia
and tarsus. The legs are dark brown, with some short yellow
and white hairs.

The cephalothorax in the male may be like that of the
female, but in our examples the hairs are almost all rubbed off
showing the dark, iridescent cephalic plate. Some of them
have a line of white hairs running along the sides of the
cephalic part and curving around the edge of the crescent-
shaped thoracic plate. The abdomen is usually lke that of the
female, although in one or two examples the whole surface is
covered with gold-colored hairs, excepting the black and white
bands around the anterior end, as shown in the figure. The
palpus has short white hairs on the patella, and long black
hairs on the tibia and tarsus. The first and second legs are
darker in color than the third and fourth and are ornamented
with double fringes of hair, which, however, are not nearly so
long and striking as in &. conspecta. The fringes on the upper
edges are black, while those below are longer and of a brownish
color.

We have numerous examples from the eastern part of
Guatemala. The species is easily distinguished by its small
size and the distinct pattern on the abdomen. In form and

46 PECKHAM. [Vol. 3.

general appearance it closely resembles the other species of this
genus.

@. Length, 7. Length of cephalothorax, 3; width of

This species has the cephalothorax only moderately high,
the highest point being at the dorsal eyes, from which it slopes
in both directions, much more steeply behind than in front.
The upper surface of the anterior thoracic part forms a crescent-
shaped plate as in parvula, and from this the drop to the mar-
gin is still more abrupt. The sides are vertical and parallel in
the cephalic part, rounding out from above below and also
widening somewhat in the thoracic. The first row of eyes is
straight, which is unusual in this genus. The quadrangle
of the eyes is a little wider in front than behind, is one-fourth
wider than long, and occupies about one-half of the cephalo-
thorax. The third row of eyes is not quite as wide as the
cephalothorax at that place, and the eyes of this row are
rather large. There is a distinct post-ocular depression. The
falces are vertical and stout with a small fang.

The cephalothorax is dark reddish brown with white
bands on the sides and a white band running from the dorsal
eyes around the curved thoracic plate. The abdominal mark-
ings are best seen under alcohol, the pattern becoming indis-
tinct when the spider is dried. The general color is dark
brown. On the front end are two oblique bands of reddish
yellow, almost orange color, from the inner side of each of which,
behind, comes off a band which bends inward, giving some-
what the effect of a parenthesis. There is a pale band down
the middle of the dorsum which widens behind and is
broken into cheyrons on the posterior half. Just behind the
inner branches of the yellow bands is a pair of white spots, and
on the posterior part, on either side of the band of chevrons, is

a blackish region, which is crossed by two larger white spots.
The palpus is yellow, rather thickly covered with white hairs.
The legs are yellow, with short brownish hairs.

We have a single female from the eastern part of Guate-
mala.

. Although this species differs from the others of this genus
in having the first row of eyes straight and the quadrangle
occupying half of the cephalothorax, it closely resembles them
in general shape, and in the pattern on the abdomen.

DENDRYPHANTES (c. kocu).
Plate IV, figs. 3—-3b.

Spiders varying from small to above medium size.

The cephalothorax is from moderately high to high. The
cephalic plate is usually level in the posterior half, but is in-
clined in front. Behind the dorsal eyes the cephalothorax is
either level or else slopes more or less, in the first part of the
thorax, and then falls abruptly. The sides diverge a little from
the first row of eyes, but are only a little wider than the third
row at that place. Behind the dorsal eyes they are plainly
widened out. The anterior eyes form a curved row, the lateral
being more than one-half as large as the middle and separated
fromthem. ‘The second row is nearer the first than the third.
The quadrangle of the eyes is one-third wider than long, is
wider behind than in front, and occupies from two-fifths to
nearly one-half of the cephalothorax.

The species of Dendryphantes that we have from Central
America are nitidus, letabilis, hondurensis, dubitabilis and centralis,
described below; ruber P., described under the genus Philzus
in our paper on New Genera and Species of Attide from Guate-
mala, Proc. Nat. Hist. Soc. of Wis., Dec. 1885, p. 66, and capi-
datus Hentz, described in Spiders of United States, and also in our
paper on North American Attidex.

Of these, nitidus is much larger than any of the others.
The males of nitidus, lxtabilis and ruber are easily distinguished

from each other and from hondurensis and centralis by their
peculiar falces. -Capitatus, centralis,dubitabilis and hondurensis
differ from each other in the shape of the cephalothorax.

The shape of the cephalothorax differs a little with the
sexes. In the malethe upper surface is almost level, excepting
a slight elevation at the dorsal eye, from the second row of eyes
through half the length of the thoracic part, falling steeply both
in front and behind. In the female the cephalic and thoracic
parts slope in opposite directions from the dorsal eyes, at first
very gradually and then more abruptly, the final fall being
less steep than in the male. The falces are vertical and mod-
erately long and stout, being stouter and more convex in front
in the male than in the female, but still not visible from above
as inruber and nitidus.

The general color is brown, the male being darker than the
female, and in both sexes the cephalothorax is darker than the
abdomen. In the female the whole body is covered with gray
hairs. On the dorsum of the abdomen are four pairs of black
spots, edged with white, those of the posterior pair being indented
on the inner sides. The hairsare usually all rubbed off in pre-
served specimens, and when this is the case the appearance of
the abdomen is much changed, the integument being of a light
brown color, streaked and spotted with a paler shade, with two
hairs of pale colored or white spots on the anterior part, and
two pairs of oblique pale bars on the posterior. ‘The legs are
light brown, barred with darker, with some close white scales.

No. 1.] ATTIDA OF CENTRAL AMERICA. 49

They are not at all hairy. The palpi are brown, with gray
hairs, and the falees are brownish-red.

The male has the cephalothorax almost black, with a band
of white hairs on each side just below the eyes, and another
low down around the margin. One of our specimens has a
few iridescent red and blue scales left on the cephalic plate.
On the abdomen the hairs are snowy white, but they are nearly
all rubbed off excepting around the front end, the integument
sometimes showing a pattern similar to that of the female, but
with the pale spots elongated into wavy bands which approach
each other down the middle line.

Others have a white band, which runs around the anterior
end of the abdomen and is broken up into white spots on the
posterior sides, while on the dark brown dorsum are two longi-
tudinal rows of white spots. In some specimens of both males
and females the darker parts predominate, the abdomen being
pale yellowish brown, with three or four pairs of dark spots,
which are connected with a dark marking down the middle.

We have numerous examples from Guatemala and British
Honduras.

The colors and markings of the female of hondurensis
are almost identical with those of D. capitatus, but in that species
the female has the cephalothorax level above, and sloping
abruptly before and behind.

This species is very close to hondurensis and capitatus, the
markings being very similar although not quite identical.
The shape of the cephalothorax, however, is different. The

50 PECKHAM. [Vol. 3.

cephalic plate is level from the dorsal eyes to just above the
anterior eyes, and is then inclined forward, while the thoracic
part rounds off abruptly from the dorsal eyes, and then falls
still more steeply in the posterior half. In capitatus the thorax
is level for some distance behind the dorsal eyes, and in hondu-
rensis it falls very gradually. The falces are vertical and
moderately long and stout.

The color of the cephalothorax is dark brown, pretty well
covered with yellowish gray hairs, which grow long and thick
on the clypeus. The abdomen seems to have been covered
with short white hairs, but as our specimens are rubbed nearly
bare, it is impossible to say what the original appearance of the
spider was. The integument is of a pale brownish color. On
the dorsum are four pairs of dark spots. The first pair is close
to the second, and the two spots are connected by a dark band
which runs across the front of the abdomen. In the pale space
thus marked off, are four black dots. On the posterior part of
the dorsum the dark spots are connected with a dark marking
down the middle, so that there are alternating pale and dark
wavy bands. The palpi are light brown, with gray hairs.
The femur, patella and tibia of the first leg are dark brown,
deepening to black on the sides, the femur having a pale
space underneath. They are thinly covered with white hairs.
The metatarsus and tarsus are yellow. The femoral joints
of the other legs are pale. That of the second has a large
dark spot on each side at the extremity, while those of the
third and fourth have a dark band. The legs are otherwise
yellow, with dark rings at the ends of the joints. The falces
are dark reddish-brown.

We have one male and five females from Panama.

The cephalothorax is high and convex, falling directly
behind the dorsal eyes, the slope becoming steeper after the
first third of the thoracic part. It is rounded on the sides,
though not so much so as in nitidus. The cephalic part oc-
cupies nearly one-half of the cephalothorax. The clypeus is
only one-fifth as high as the anterior middle eyes. The falces
are oblique and heavy, with two long stout teeth on the lower
side. The fang is as long as the falx. The middle eyes of
the first row are nearly twice as large as the lateral. The
palpus is long and slender.

Our single specimen has been badly rubbed. Under al-
cohol it is black, with two patches of white hairs on each
side of the cephalic part, one in front of the dorsal and one
in front of the small lateral eyes, and with a white band
encircling the abdomen. When dry, patches of brilliant iri-
descent scales appear on the cephalic plate and on the central

dark bronze brown. The other legs are lighter brown, varied
with yellowish, the proximal ends of the femoral joints being

The cephalothorax is high, and is widest at and just
behind the dorsal eyes. The sides are vertical in the cepha-
lic part, but broaden out a little at the lower edge, in the
thoracic. The cephalic part is inclined. The thoracic falls
from the dorsal eyes, gradually in the first third, and then
more steeply. The quadrangle of the eyes is plainly wider
behind than in front, and at its widest point is one-fourth
wider than long. It occupies nearly one-half of the cephalo-
thorax. The anterior eyes are not very large. They are a
little separated and form a straight row, the middle being
nearly twice as large as the lateral. The second row is nearer
the first than the third. The third row is scarcely narrower
than the cephalothorax. The falces are vertical, and moder-
ately stout and long. The clypeus is one-third as high as the
large middle eyes. The first legs are considerably stouter than
the others.

Our specimens have been badly rubbed. The cephalo-
thorax is black with a narrow band of white hairs around the
lower margin, and patches of white and of iridescent hairs. The
abdomen is brown or black, covered with hairs of a bright gold-
en yellow color. There is a white band around the anterior
end, a pair of white spots on the anterior part, and two trans-
verse white bands on each side, behind the middle, which curve
upward from the sides. The legs are dark brown, more or less
banded with a lighter shade. ‘The palpus is brown with white
hairs.

This spider is so much larger than the other species of
Dendryphantes that are found in Central America that it is
easily distinguished from them. The cephalothorax is
rounded, the outline of the sides being nearly circular in
the male, though not in the female. The cephalic plate
is level from the third to the second row of eyes and
is then inclined forward. The thoracic part rounds off
from the dorsal eyes, falling gradually at first and then more
steeply. The falces in the male are long, obliquely directed
and divergent with along fang. In the female they are vertical,
stout and long, and are very convex in front, so that they are
plainly visible from above. The fang is strong. The palpus
is long and slender.

The coloration at once recalls that of D. militaris, which
is found as far south as Mexico, but differs from it in having iri-
descent scales on the abdomen in both sexes. The male is of
a bronze brown color. The cephalothorax has a white band
passing across the clypeus and around the sides, stopping
behind where the abdomen overlaps. Near the lower margin
isa black line upon the white. Between the dorsal eyes is a
patch of snow-white hairs. The hairs around the anterior
eyes are yellow. The abdomen is encircled by a white band,
within which, on each side of the dorsum, is a dark longi-
tudinal band. These dark bands are sometimes broken up

54 PECKHAM. [Vol. 3.

into four pairs of large dark spots. The first pair of these
spots (or the corresponding parts of the bands) have on their
inner side a small white spot; the space between the second
pair is filled in with a large white spot; on the posterior half
of the dorsum are three pairs of short transverse white bars,
which separate the second and third and third and fourth pairs
of dark spots, and outline the posterior end of the fourth
pair. All over the rest of the dorsum, around and between
the spots and bands, the abdomen seems to have been covered
with beautiful iridescent scales with light green and red reflec-
tions. Of these, only patches are left in our specimens. The
legs are brown barred with black, those of the first pair being
much the darkest. They have a thin covering of short dark
hairs, and a good many close white scales. The palpus has
long dark hairs on the tarsus and white scales on the other
joints. The falces are bronze brown and slightly iridescent.

The coloring of the female is essentially like that of the
male. The cephalothorax is covered, except the marginal
black line, with white hairs, having no yellow around the eyes.
The abdomen has the encircling white band broken into
oblique bars on the sides; and the dark bands are more com-
monly broken into distinct parts. There are long white hairs
on the palpus.

We have numerous specimens, both of males and females,
from Guatemala.

NAGAINA, GEN. Nov.

The cephalothorax is only moderately high. The upper
surface is gently convex from the second row of eyes through
two-thirds of the thoracic part, the inclination in front of and
behind the dorsal eyes being about the same. The anterior
end of the cephalic part is more distinctly inclined, and the
posterior end of the thoracic falls abruptly. The sides are
contracted in front and behind, the widest point being just back
of the dorsal eyes; they are vertical in front and nearly so
behind.

No. 1.] ATTID 4) OF CENTRAL AMERICA. 55

The quadrangle of the eyes is a little wider behind than in
front, is one-fourth wider than long, and occupies nearly one-
half of the cephalothorax. ‘The anterior eyes are a little sepa-
rated from each other, in a slightly curved row, the middle being
nearly twice as large as the lateral. The second row is a very
little nearer the first than the third. The dorsal eves are large
and prominent, and form a row which is scarcely narrower
than the cephalothorax at that place.

The single individual upon which this genus rests, most
strongly recalls some of the smaller species of Dendryphantes
in the shape of the abdomen and the character of the mark-
ings, but differs from them in the nearly vertical sides of the
cephalothorax.

dots. The abdomen has the outer sides pale yellow with some
flecks of dark brown. Down the middle is a branching band
of pale yellow, and on either side of this band is an irregular
region of brown, which is more or less dotted with yellow.
When the specimen is dried a few white scales appear both on
the cephalothorax and on the abdomen.

The legs are pale yellow. The first has the joints some-
what enlarged, especially the femur, which has three stiff black
hairs on the upper surface and a black spot, above, near the
distal end. This black spot is repeated on the upper surface of
the patella and of the tibia.

HASARIUS (£. stmoy).
Plate V, figs. 1—-1b.

The cephalothorax is rather high and moderately long.
The cephalic part is slightly inclined forward; the thoracic
falls very little, or not at all, for about half its length and
then more abruptly. It is more or less contracted in front,
and widens out behind the dorsal eyes. The sides of the
cephalic part are sometimes nearly vertical; in the thoracic
they widen out distinctly from above to the lower edge. The
quadrangle of the eyes is equally wide in front and behind,
or a little wider in front, is from one-fourth to one-third
wider than long and occupies about two-fifths of the cephalo-
thorax. The anterior eyes form a straight or slightly curved
row, the middle being subtouching or a little separated and less
than twice as large as the lateral, which are more widely re-
moved from them. The second row isabout half-way between
the first and the third; the third row is nearly or quite as wide
as the cephalothorax at that place.

Hasarius belongs to the group of genera of which Phidip-
pus is the representative, as being the strongest and most widely
known. It has no very strongly marked characteristics, but it
includes a considerable number of species, which are of medium
size, or larger, and are widely distributed. It is, perhaps, most
closely related to Plexippus, but is readily distinguished from
that genus by the longer cephalic part and by the more nearly
parallel sides of the cephalothorax. We give generic drawings
of the type species, H. Adansonit.

The anterior eyes forma very slightly curved row; the middle
eyes are close together, the lateral a little separated from them.
The third row is just about as wide as the cephalothorax at
that place. The clypeus is about one-fourth as high as the
middle anterior eyes and the falces are vertical, moderately
long, and not very stout.

The cephalothorax has the cephalic part black, and the
sides and thoracic part brown, with a central white band.
The abdomen has a white band down the middle, on the edges
of which are three pairs of white spots, and a white band on
each side at the front end. On either side of the central
band the color is blackish, and the outer sides are brown.
The whole abdomen is covered with scanty gray hairs. ‘lhe
falces are brown, the palpi yellow with gray hairs, the legs
brown with black spies and gray hairs, the first pair being
the darkest.

We have a single female from the eastern part of Guate-
mala.

AVITUS, GEN. Nov.

The cephalothorax is moderately high and is one-third
longer than wide. The cephalic part is slightly inclined. The
thoracic falls very gradually through one-half of its length,
and then more steeply. The sides widen out plainly from the
first row of eyes, reaching the widest point just behind the
dorsal eyes, and then contracting again. They are nowhere
vertical, spreading out from above throughout their length,
most widely at the widest point of the cephalothorax. The
quadrangle of the eyes is slightly wider behind than in front,
is one-fourth wider than long, and occupies two-fifths of the
cephalothorax. The anterior eyes are ina slightly curved row,
the lateral being half as large as the middle and separated
from them, while the middle eyes are close together. The
second row is about twice as far from the third as from the first

58 PECKHAM. [Vol. 3.

row. The third row is plainly narrower than the cephalo-
thorax at that place. The first leg greatly exceeds the others
through the elongation of the coxa and trochanter, which, taken
together, are a little shorter than the femur, the coxa being a
little longer than the trochanter. The first leg is longer than
the second by the tibia, metatarsus and tarsus. The coxa of
the first is nearly twice as long as the coxa and trochanter of
the second taken together.

This genus belongs to Simon’s “Groupe des Diolenii”
(Comptes-rendus de la Société Entomologique de Belgique,
Séance du 5 Juillet, 1884), which has hitherto been thought to
be confined to the Malay Archipelago and Australia.

The form and relative length of the joints of the first leg
and the length of the cephalic part distinguish it from the
other genera of the group.

few white hairs are left,on the sides and above. The abdomen
is of a much lighter brown with a white band around the an-
terior end and along the sides, and two pairs of white spots,
one on the anterior part of the dorsum and one about in the
middle, the anterior two being connected by slender lines

which run obliquely forward from the spots. The hairs being
nearly all gone, these spots appear dark under alcohol, as seen
in the figure. The legs, palpi and falces are all dark brown.

HABROCESTUM (&. simon).

The cephalothorax is convex, high and rather short, and
widens out a little in the thoracic part. The cephalic part is
inclined forward. The thoracic remains level or slopes very
gradually for some distance behind the dorsal eyes. The sides
are vertical or nearly vertical in front, and slant outward in
the thoracic part. The quadrangle of the eyes is equally wide
in front and behind, is one-third wider than long and occupies
two-fifths of the cephalothorax. The anterior eyes are in a
straight orslightly curved row, the middle being twice or nearly
twice as large as the lateral, which are separated from them.
The second row is usually half-way between the first and the
third. The third row is as wide or nearly as wide as the cepha-
lothorax at that place.

The females of this genus resemble each other closely. The
males are more brightly colored and have a strong tendency
to leg variation, the first or the third, or both the first and the
third legs being often ornamented with tufts and fringes of
variously colored hairs, and with apophyses. The palpi of the
males are much alike, the bulb being short and almost circular
in form. ‘

Habrocestum is near Satis, but the quadrangle is never
wider in front than behind, and, so far as we know, the third
leg is always longer than the fourth.

We consider Habrocestum a good representative of the
group which includes Saitis, Huophrys, Attus, Cyrba, Heliophanus
and the allied genera. The species are of medium size or
smaller, and have a wide distribution. They are very numer-
ous throughout the United States. We give a drawing of H.
auratum, Hentz, as fairly typicalof the genus. (PI. V, figs. 4-4b.)

the sides and the thoracic part. The clypeus is covered with
long white hairs. The abdomen is covered with fawn-colored
hairs, the lower sides having some oblique, rather indistinct,
white bands. Along the upper sides are two black scallops,
more distinct in some specimens than in others. On the cen-
tral posterior part are some white chevrons, outlined in black.
On each side, the scalloped black line runs down and meets the
black line at the sides of the chevrons, making a distinct point.
Close to the spinnerets are two parallel white bars which some-
times join with the last chevron to make a somewhat horse-shoe
shaped mark. The legs and palpi are reddish brown with
white hairs.

The cephalothorax has the hairs fawn-colored on the
cephalic plate, and white on the sides and thoracic part, as in
belligerum, but the integument is darker, being black instead of
medium brown. The abdomen is covered with yellow hairs
with a whitish band around the base and sides. On the pos-
terior third of the dorsum (not the posterior half, as in belli-
gerum) are some alternating black and light chevrons, and
near the spinnerets, a somewhat crescent-shaped white figure,
at each outer side of which is a white spot. The different parts
of this figure vary in distinctness. The legs are dark reddish-
brown with some short white hairs.

This species is very close to delligerum, but is a little larger
and decidedly darker. It has not the black scalloped marks
on the abdomen that appear in some examples of that species,
it has the chevrons more crowded together at the posterior end,
and it lacks the black point on each side of the posterior part.

The cephalic plate is covered with short hairs of a soft fawn-
color, with some longer black hairs. The upper surface of the
thoracic part seems to have been covered with pure white
hairs. Around the lower edge is a narrow band of white hairs,
and above this the sides seem to have been covered with short

yellow hairs. The abdomen has a white band around the base
and sides and another band down the middle, which breaks up
into small chevrons on the posterior part. On each side of the
central band the dorsum is covered with a mixture of white
and yellowish brown hairs.

The first leg has the femur and patella black on the upper
surface, with a fringe of brownish hairs on each side, that on
the front side being much the longer and heavier, with a
pure white line running along the joints just above it. The
other joints are covered with white hairs. The second leg is
light colored with a black ine along the upper surface of
the femur, and is otherwise covered with white hairs. The
third leg is also light ; the femur has a black line along the upper
surface on the front side and a second one, half as long, on the
back side ; at the end of this joint isa rounded enlargement, with
a black spot in the middle; the patella has two black lines
above; the tibia has a greenish color on the front face and
some long white spines, and is otherwise covered with white
hairs; the other joints are ight with white hairs. The fourth
leg has the femur ght with an indistinct black line, and has
the distal end darkened; the patella and tibia are light with
black flecks; the other joints are hght with dark hairs. The
palpus has long white hairs and the clypeus is covered with
short white down. The falces have some long white hairs
on the front face.

The female has a dark integument entirely covered with
white hairs which have a slight fawn-colored tinge. These
hairs grow rather thinly over most of the surface, but thicken
so as to form three distinct longitudinal bands on the cepha-
lothorax, one down the middle, and one on each side, in-
cluding the line of eyes along each side, and also to form a
pair of spots on the middle of the abdomen, two triangular
spots at the posterior end, and two short curyed bands on
each side. The clypeus is covered with long white hairs,
and there are some long black hairs standing up over the first

the cephalic. The upper surface is sometimes flat for
a little distance both in front of and behind the dorsal
eyes, and sometimes slants from them in both directions,
the posterior part of the thoracic part falling more steeply than
the first half. The sides are vertical, or nearly vertical, in the
cephalic part and slant outward a little in the thoracic.

The quadrangle of the eyes is equally wide in front and
behind or a little wider in front, is one-fourth or one-third
wider than long and occupies about two-fifths of the cephalo-
thorax. The anterior eyes are rather large, and are close
together in a straight, or a slightly curved row, the lateral
being about two-thirds as large as the middle. The second row
is half-way between the other two or is nearer the third row.
The third row is sometimes as wide as the cephalothorax at

Euophrys, which has so many species in Europe, is but

acters. The species are usually small, rarely reaching medium

inclination backward and forward being about the same. The
second half of the thoracic part falls a little more steeply, the
slope being almost in the same direction throughout. The
sides widen out very gradually as far as the middle of the

Buophrys, the sides are pinched together in the middle of the
cephalic part, and then widen out quite suddenly. The second
row of eyes is nearer the third than the first. The sides slant

The cephalothorax is reddish-brown, darkest in the cephalic
region, with a black rim around the margin. Our specimen is
rubbed, but there seems to have been a covering of white and
reddish-yellow hairs over both cephalic and thoracic parts.
There are some long red hairs over the first row of eyes. The
integument of the abdomen is of a pale yellowish-brown color
with a covering of short white hairs. On the back is a pattern

A medium-sized species with a distinct pattern in black,
white and red on the abdomen.

This species is like delecta in the position of the eyes and
the shape of the cephalothorax, excepting that it rounds off
more suddenly from the dorsal eyes, falling decidedly in the
first third of the thoracic part and then still moresteeply. The
falces are vertical and are small in the female, while in the
male they are moderately long and stout. The clypeus is
inclined backward.

The cephalothorax of the female is black covered with red
hairs. There are two transverse white bands, one just above
the anterior eyes and the other at the dorsal eyes, and on the

No. 1.| ATTIDA OF CENTRAL AMERICA. 67

central thoracic part is a large white spot. A wide white band
crosses the clypeus and passes around the sides, somewhat above
the lower margin, as far as the hinder corners of the thoracic
part.

The pattern on the abdomen of the female is almost iden-
tical with that of delecta. There is a wide curved white band
across the anterior end, followed by a band which, instead of
being bright red, as in the other species, is made up of black
with an intermingling of red hairs, resulting in a very rich,
but dark shade. Behind this is a central herring-bone stripe
in white with black on each side, the black being broken by two
pairs of white spots and by white scallops on the lower sides. The
first and largest portion of the herring-bone stripe is sometimes
connected with the white which comes up over the sides from
below, thus forming a second white band across the abdomen
in front of the middle. The palpus is yellow, with scanty
white hairs. The legs are barred or ringed with yellow and
brown.

We have two males, both of which are badly rubbed.
The legs, palpi and falcesare all black. The cephalothorax has
a black integument covered with yellowish-red hairs and is
marked with white, as in the female. The abdomen is covered
with yellowish-red hairs excepting a white band around the front
end, two white spots on each side, and two pairs of white spots
behind the middle of the back. The ground color is not so
bright a red as in the female, but this may be owing to the fact
that we have imperfect specimens.

We have numerous examples from Chapoda and Santarem,
Brazil, and one female from Guatemala.

A handsome, medium-sized species, strikingly marked with
black, white and red.

The cephalothorax is moderately high. From its highest
point, at the dorsal eyes, it falls forward to the first row of eyes
and backward for about two-thirds of the length of the thoracic
part, the forward slope being more pronounced than the back-
ward.. The final fall to the posterior border is steep. The sides
are nearly vertical and parallel in the cephalic part, but are
rounded out in the thoracic, the widest point being considera-
bly behind the dorsal eyes. The quadrangle of the eyes is
about equally wide in front and behind, is one-fourth wider
than long and occupies two-fifths of the cephalothorax. The
first row of eyes has the tops of the middle eyes a little higher
than the tops of the lateral, so that it may be said to be curved
downward. The middle eyes are close together and area little
less than twice as large as the lateral, which are slightly sepa-
rated from them and are directed a little sideways. The sec-
ond row is half-way between the first and the third. The third
row is scarcely narrower than the cephalothorax at that place.
The clypeus is about half as high as the anterior middle eyes.
The falces are small and are directed backward.

The cephalothorax of the female has a dark region on
each side of the upper surface which usually extends, behind,
to the margin, but sometimes stops a little short of this. On
the sides the integument is pale, and is covered with white
hairs. The central space is occupied by a white band which
has on its outer sides some red hairs. Red hairs are also seen
around the anterior eyes. The abdomen of the female has a

No. 1.] ATTIDA OF CENTRAL AMERICA. 69

wide curved band of white hairs across the anterior end, fol-
lowed by a similar band of brilliant red hairs, back of which is
a second band of white, which is extended down the middle
line to the spinnerets by a narrow white herring-bone stripe.
On the sides of this stripe are two somewhat triangular regions
covered with black hairs, with which a few red hairs are mixed,
on which are two pairs of white spots. The outer sides of these
black regions are scalloped with white. In one of our females
the anterior white band sends a projection backward in the
middle line, while the second white band widens in the mid-
dle of the dorsum and has, just at the beginning of the her-
ring-bone stripe, a small central spot of mingled black and red
hairs. The clypeus is covered with long white hairs, the tips
of which meet in the middle line. Some short white hairs
grow down over the falces. The palpus is yellow, with scanty
white hairs. All the legs have the femoral joints pale yellow.
The first and second pairs have the patella and tibia dark with
a light streak above and below. The third and fourth pairs
are barred with yellow and dark brown.

The male is darker colored than the female. The cepha-
lothorax is black with wide white bands on the sides, a central
white spot on the front part of the head and another behind
the dorsaleyes. The abdomen, under alcohol, islike that of the
female, but when dry, in two of our three specimens it 1s cov-
ered with red hairs excepting the anterior white band, some
small white chevrons in the middle line of the posterior part,
the four white spots and the white scallops on the posterior
sides. In the third specimenthe red hairs extend entirely over
the second white band, but it is otherwise like the female.
The palpus is covered with white hairs as far as the tarsus,
which is black. The first and second pairs of legs are dark
with some scanty white hairs growing on the under side of the
femoral joints. The third and fourth pairs are barred with
lighter and darker brown.

In both sexes the venter usually, but not always, shows a
rectangular pale region on which is a central dark streak, and
a dark band, sometimes broken into spots, on each side.

70 PECKHAM. [Vol. 3.

We have three males and numerous females from the east-
ern part of Guatemala.

The two species of Cyrene here published bear a strong re-
semblance to each other and also to the type species decorata,
described in our paper, St. Vincent Attidx, Proc. Zool. Soc.
of London, Noy. 21, 1893. The red cephalic plate in decorata
as well as the difference in the pattern on the abdomen should
serve to distinguish it, even if it were found in the same locality
as the other species.

HAMILLUS, GEN. Noy.

The cephalothorax is rather high; the highest place being
at the dorsal eyes, from which point the upper surface slopes
forward gently, and backward in a gradual rounded slope
through one-third of the thoracic part, and then more steeply
to the margin. The thoracic plate or upper surface of the
thoracic part just behind the dorsal eyes is crescent-shaped.
The cephalic part is sometimes a little wider, sometimes not quite
so wide, as the thoracic. The sides are vertical in the cephalic
part, the third row of eyes being as wide or nearly as wide as
the cephalothorax at that place. The anterior eyes are rather
large and a little separated and form a row which is straight or
curves downward, the tops of the middle being higher than the
tops of the lateral eyes. The middle are less than twice as large
as the lateral. The second row is nearer the third than the
first. The quadrangle of the eyes is wider in front than behind,
is one-third wider than long, and occupies almost half of the
cephalothorax.

This genus finds its nearest allies in the Habrocestum
Group. It is close to Prostheclina, but has the cephalothorax
wider at the dorsal eyes than in front, with the upper surface
sloping more steeply behind than in front of the dorsal eyes,
and the first row of eyes sometimes curved downward, in all of
which particulars it differs from that genus. The shape of the
cephalothorax and the curve of the first row of eyes also dis-
tinguishes it from Agobardus, and from Sidusa.

Cephalothorax broader and longer than abdomen. Gen-
eral color dark, except palpi, which are pale yellow.

The falces of this speciesare stout and rather long, and are
inclined forward so that they are partly visible from above.
On the upper part of the inner sides is a pair of sharp teeth,
which are seen from above, projecting between the middle an-
terior eyes. ‘The clypeus is narrow.

The cephalothorax is dark brown on the cephalic part and
blackish on the sides and behind, with a pale streak down the
middle of the thoracic part. When dry it is seen to have iri-
descent hairs around the eyes and on the sides of the cephalic
part.

Under alcohol the abdomen is brown around the front
end and pale on the dorsum. On the anterior part is a central
brown band, on which is a pale spot, and two curved brown
bands, one on each side. The posterior sides are brown, while
the central region is occupied by a triangular pale space on
which are several small brown chevrons. When dry the re-
lative importance of the colors is reversed, so that the anterior
part of the abdomen is brown with a white curved band in
front, a pale spot in the middle and a pale band on each side,
which branches in the anterior half, both ends reaching the
curved white band and thus enclosing a brown spot. The
outer spinnerets are dark, the inner ones pale. The palpi are
very pale yellow with some reddish streaks on the tarsus, and
are clothed with white hairs. The legs are all alike, having
the femur dark brown, the patella pale brown, the tibia and
metatarsus medium brown, and the tarsus pale. The falces
are of a bright glistening brown.

12 PECKHAM. [Vol. 3.

This species differs from radians in haying the cephalic
part wider than the thoracic, the cephalothorax being a little
wider at the dorsal eyes than in front, and in having the third
row of eyes fully as wide as the cephalothorax at that place,
and the first row curved downward.

We have asingle male from the eastern part of Guatemala.

The sides of the cephalothorax are not far from parallel,
but there is a slight widening from the first row of eyes to a
point near the posterior end, where they begin to contract.
They are vertical in front, but slant outward a little in the
thoracic part. The clypeus is very narrow. The falces are
vertical, rounded, short and stout.

The cephalothorax is bright brown. The cephalic part
and a crescent-shaped plate behind the dorsal eyes are yellow,
covered with iridescent scales. This iridescent region is
bounded by a line of white hairs, which curves around outside
the dorsal eyes and forms a scalloped line behind them.

The drab colored integument of the abdomen seems to
have been covered with iridescent scales. Across the anterior
end and around the sides is a white band which is irregularly
scalloped on the inner sides. From this, behind the middle,
two pairs of white bands extend upward, over the back. At
the spinnerets are two white spots, joined in front by a white
chevron,

The first legs are bright brown, the femoral joints being the
darkest. The other legs and the palpi are light yellow. The
clypeus is edged with white hairs.

We have a single female, sent to us by Count Keyserling,
from Panama.

Our only specimen of this species has the front part of the
cephalothorax broken so that the shape is uncertain, and we
therefore have not put it into any closely defined genus. The
clear marking of the abdomen, however, should make it easily
recognizable.

9. Length, 6. Length of cephalothorax, 3; width of

The cephalothorax is not high, and seems to have had the
upper surface level from the anterior eyes through the first
third of the thoracic part, with the exception of a shght hump
above the dorsal eye. The anterior eyes form a straight row,
the middle being twice as large as the lateral. The second
row is half-way between the first and third. The third row is
shghtly narrower than the cephalothorax at that place. The
cephalothorax is long, and the cephalic part occupies a little
less than two-fifths of it.

The color of the cephalothorax is yellowish-brown, the
eye-region being a little darker than the rest. There are some
yellowish-white hairs on the sides below the second and third
rows of eyes, and around the jower margin. The abdomen is
pure white with two black longitudinal bands which meet in
front and behind. On the outer side of each of these, near the
posterior end, is an oblique line of white, directed backward.
On the lower sides are some slender black lines formed by
hairs. The first leg has the femur pale, and the other joints
yellowish brown. The other legs are all pale, with fine black
spines.

We have one female from Panama, sent to us by Count
Keyserling.

The cephalothorax is rather high, and is wide in the
thoracic part. The sides begin to widen out in front of the
dorsal eyes, the widest point being beyond the middle of the
thorax. They are vertical at the second row of eyes, but from
that point they begin to spread out below, the upper surface of
the thoracic part being plainly narrower than the lower. The
cephalic part is inclined forward. he thoracic falls from the
dorsal eves in a gradual slope for two-thirds of its length, and
then drops steeply. The quadrangle of the eyes is wider in
front than behind and occupies two-fifths of the cephalothorax.
At its widest point, in front, it is but one-fifth wider than long,
and behind, the width scarcely exceeds the length. The
anterior eyes are a little separated from each other, and form a
straight row, the middle being nearly twice as large as the
lateral. The second row of eyes is half-way between the first
and the third. The third row is narrower than the cephalo-
thorax at that place. There is a large depression between the
dorsal eyes.

In the figure, the first row of eyes appears to be strongly
curved, owing to the fact that the spider was drawn in a tilted
position.

The clypeus is more than one-half as high as the middle
eyes of the first row. The falces are vertical, of nearly the
same size all the way down, and notched on the lower edge.

Under alcohol, the cephalothorax isa bright reddish brown,
with a wide white band extending across the clypeus and encir-
cling the sides, the two ends almost meeting behind. There is
a white band above the first row of eyes, and a central white
band on the thoracic part. The abdomen is pure white with

No. 1.] ATTIDA OF CENTRAL AMERICA. 75

two longitudinal, curved reddish-brown bands on the dorsum.
The palpus has the patella and tibia white and the tarsus red-
dish with long reddish-yellow hairs, which are sometimes
mingled with long white hairs. The legs are brown, those of
the first and second pairs being darker than the others, with
some short white hairs. The first leg has, in one example, a
pale patch on the upper surface of the patella, while another
has a blackish streak along the anterior face as far as the end
of the tibia. The falces are bright reddish-brown with some
long white hairs on their front face. When the spider is dry,
short yellow hairs appear on the cephalothorax above the
white bands; the abdomen is seen to be covered with hairs,
the bands being of a rich reddish color which contrasts with
the pure white background; and each of the bands has, in
front, on the inner side, a yellowish lozenge-shaped spot with-
out hairs, which makes the central white band considerably
narrower at the anteriorend. Low down on the front part of
the abdomen is a short wide dark brown band extending only
across the front surface. In one example the red hairs are
rubbed from the bands on the abdomen, leaving them dark
brown covered with small yellow speckles.

We have two males from New Grenada, sent to us by
Count Keyserling, and one from Guatemala in our own collec-
tion.

A graceful, medium-sized species, the abdomen marked

Although we put this species into Menemerus it does not
conform very closely to the characteristics of that genus. The
quadrangle of the eyes is wider in front than behind, is barely
one-sixth wider than long, and occupies very nearly one-half of
the cephalothorax. The anterior eyesare in a curved row and

are slightly separated from each other, the middle being twice
as large as the lateral. The second row is plainly nearer the
first than the third. The third row is narrower than the
cephalothorax, the sides being nowhere vertical. ‘The cephalo-
thorax is not high, and is gently convex above, rising from the
first to the third row of eyes and then falling a very little
through the first half of the thoracic part.

The clypeus is one-fourth as high as the large middle eyes.
The falces project forward ; they are long and rather stout.

The cephalothorax is dark reddish-brown, darkest on the
cephalic plate. There is a wide white band with a narrow black
line around the margin, and a white transverse band in front
of the third row of eyes. The clypeus is covered with white
hairs. he falces are dark red and rugose. ‘The abdomen is
encircled by a white band. The dorsumis bright yellowish-
red with a slender longitudinal white line down the middle.
The palpi and legs are of rather a light brown.

We have a single male from the eastern part of Guatemala.

HERACLEA, GEN. Nov.

Rather large spiders.

The cephalothorax is from moderately high to high and
is widest behind the dorsal eves. The cephalic part is inclined ;
the thoracic sometimes rounds off directly behind the dorsal
’ eyes, falling in an unbroken curve to the posterior border, and
sometimes falls very slightly in its first half, and then more
steeply. The whole cephalothorax is wide on the upper sur-
face, being nearly as wide above as below. The quadrangle of
the eyes is wider in front than behind, is one-fourth wider than
long and occupies from two-fifths to nearly one-half of the
cephalothorax. ‘The first row of eyes is straight with the eyes
all a little separated, and rather large, the lateral being more
than half as large as the middle. ‘The second row is half-way
between the first and the third or a little nearer the first. The
third row is narrower than the cephalothorax at that place.

This genus seems to be nearest Mpinga P. (Attide of the

Marptusa Group, Oce. Papers Nat. Hist. Soc. of Wisconsin, Vol.
II, No. 2, p. 94). The cephalothorax, however, falls more or less
steeply from the dorsal eyes, even in H. regia, which is the
flattest of the three species here described. Heraclea, too, lacks
the low long flat look of Epinga, the abdomens, although
rather slender, not being so long, narrow and cylindrical as in
that genus.

The colors are red, white and black.

The cephalothorax is moderately high. It slopes upward
to the third row of eyes and then, in the female, falls very
gradually through half of the thoracic part, the final fall being
a little steeper. In the male the nearly level part just behind
the dorsal eyes is shorter. The quadrangle of the eyes occu-
pies two-fifths of the cephalothorax. The second row is half-
way between the first and the third. The clypeus is about
one-third as high as the large middle eyes. The falces are
long, stout and vertical, with a relatively small fang.

The coloration is extremely striking. The cephalothorax
of the male is jet black with wide bands on the sides, a central
band on the thoracic part, and a large patch just over the first
row of eyes, all of snowy white. The palpus carries out the
same plan, the femur and patella being covered with snowy
white hairs, and the tibia and tarsus with black hairs. The
abdomen is of a very vivid red, nearly encircled by a white

band and having another white band down the middle of the
back, from a point in front of the middle, to the spinnerets.
The spinnerets are black, covered, in some specimens, with
white hairs. The legs are black, and not at all hairy. The
femoral joints of the third and fourth have a pale ring around
the middle. The clypeus is covered with snow-white hairs.
The falces are black.

-Che cephalothorax of the female is brown, with a black
ring and a narrow white line around the margin. The hairs
on the thoracic part are reddish-yellow, not at all like the color
of the abdomen, while on the cephalic part they are somewhat
iridescent. There is a small central gray patch over the ante-
rior eyes. ‘The abdomen is red, as in the male, but the curved
white band across the anterior end extends only half-way on
to the sides, the posterior sides having a blackish region upon
which is a large spot, and further back, a smaller spot of white,
the two sometimes being connected. The central white band
either stops a little way behind the middle of the back or is
continued to the spinnerets by a series of fine white chevrons.
The legs are dark brown, the femoral joints all having a broad
pale ring around the middle. The palpi are brown, heavily
covered with gray hairs. The falces are dark brown overhung
by gray hairs which grow on the edge of the clypeus.

The palpus of the male has the tibia very short and wide,
with a strong apophysis on the outer side.

We have large numbers of both sexes from the eastern
part of Guatemala.

HERACLEA SANGUINEA, SP. NOV.

Of this species we have only the male which, although
running a little smaller than that of E. regia, is almost iden-
tical with it in appearance. The palpus, however, is different.

Our examples of sanguinea lack the white hairs on the
clypeus and the white patch above the first row of eyes,
and in some of them the central white band on the abdomen
takes the form of a slender herring-bone stripe. The legs are

not black but dark brown, the first pair being darkest, and there
are no pale rings on the femoral joints of the third and fourth.
The thoracic part of the cephalothorax, instead of falling very
gradually for part of its length, and then more steeply, as in
regia, rounds off broadly from the dorsal eyes to the posterior
margin, with no point at which there is a distinct difference in
the direction of the slope, although the fall is more abrupt
toward the end. The relative length of the legs is 1324; the
first pair being plainly longer than the third.

In the female the line of the upper surface is gently curved,
the thoracic part having the same inclination as the cephalic
until just in front of the posterior border, when it falls abruptly.
In the male the thoracic part falls more steeply than the

scarcely narrower than the cephalothorax at that place. The
clypeus is one-third as high as the large middle eyes. The
falces are vertical and rather long and stout.

The cephalothorax is dark, almost black, with a white
band on each side, another across the cephalic part just above
the first row of eyes and a white streak down the middle of the
thoracic part. There are red hairs around the eyes and on the
sides of the cephalic plate. The abdomen is of a grayish color,
being covered with a mixture of black, white and red hairs.
Down the middle is a slender white herring-bone stripe which
has the edges outlined in red. In the female there is a white
band around the front end, and the herring-bone stripe is found
only on the posterior half of the abdomen. ‘The legs and palpi
are brown and not especially hairy. In the male the first
legs, excepting the tibial joints, are much darker than the others.
The second, third and fourth pairs have the femoral joints pale
yellow, excepting a ring at the distal end, which is dark brown,
making a strong contrast. Inthe female the femur of the first
is dark, with a yellow spot on the upper surface ; otherwise the
legs are like those of the male. There are some long white
hairs on the clypeus. The falces are dark brown, with white
hairs on the inner sides.

PACHOMIUS, GEN. Noy.

The cephalothorax is not very high and is plainly longer
than wide, sometimes nearly twice as long. The cephalic part
slants forward at the anterior end, but from the second row of
eyes backward to the middle of the thoracic part the upper
surface is gently convex, the dorsal eyes being at the highest
point. The convexity is much more marked in the male, the
female being almost flat. ‘The sides are not far from parallel,
there being a slight widening in the thoracic part. They are
vertical in front, but slant outward a little behind, the third
row of eyes being about as wide as the cephalothorax. The
quadrangle of the eyes is a little wider behind than in front or

equally wide in front and behind, is only one-fifth wider than
long and occupies from two-fifths to one-half of the cephalo-
thorax. The anterior eyes are nearly touching, in a straight row,
the middle being almost twice as large as the lateral. The sec-
ond row is nearer the first than the third.

This genus belongs to the Marptusa Group. ‘The outline
of the sides resembles Pseudicius, and some of the species of
Balmaceda, but it is not flat enough to be included in these
genera, the contour of the upper surface being more like Mene-
mMmerus.

toward the extremity. They are as long as the face in thé
male, and a little shorter in the female. The legs of the male
are longer than those of the female. The quadrangle of the
eyes occupies two-fifths of the cephalothorax, and is a little
wider behind than in front.

The cephalothorax of the male is dark brown or black. A
wide white band runs around the sides and across the clypeus
there is a large white spot on each side of the cephalic part
between the second and third rows of eyes, and an elongated,
central spot on the thoracic part. The color of the abdomen

varies from a dark rich red toa bright orange. A white band
passes around the anterior end and half-way down the sides,
ending in an enlargement which bends upward on to the dor-
sum. A little further back, on each side, is another white
spot, which passes upward from theside on to the back. Down
the middle is a blackish band, upon which are two large white
spots, one about in the middle and one near the spinnerets.
The legs are hght or medium brown, the first pair being the
darkest, and have patches of short white hairs. In the light
specimens the fourth leg shows a black line on each side of the
patella and tibia. The palpus is ight brown, with the upper
surface of the patella and tibia covered with snow-white hairs.
The falces are dark brown.

The cephalothorax of the female is black with only a nar-
row white line around the sides, and with the clypeus thinly
covered with white hairs. Our specimens are badly rubbed,
but show some orange colored hairs on the cephalic part and
around the anterior eyes. The palpi are yellow, thinly covered
with white hairs. The coloration is otherwise like that of the
male.

We have numerous specimens from Guatemala, New
Grenada and French Guiana.

slender look which characterizes dybowskw and similis, both
cephalothorax and abdomen being broader in proportion to
the length. The legs are longer in proportion to the body
than in similis, to which species it is closely related.

The cephalothorax, in our specimen, is somewhat rubbed.
The integument, which is black, seems to have been covered
with yellow hairs. There are white bands on the sides. The
upper part has three large white spots, one on each side of
the cephalic part just behind the eyes of the second row, and
one on the middle of the thoracic part. The clypeus is thinly
covered with white hairs. The falces are dark brown. The
anterior part of the abdomen is covered with yellow hairs ex-
cepting a white band which curvesaround the end and extends
on to the sides. An angular white band, ending, on each side,
in a white spot, crosses the back, just behind the middle.
Behind this is a black space and then a transverse curved yel-
low band, in the middle of which is a fine black chevron. The
posterior end is black, with three white spots, one in the middle,
and one low down on each side. The spinnerets are very
short. The legs are brown, marked with black, the first pair
darkest. The palpiare yellow, much lighter than the legs, and
are thinly covered with white hairs.

This species, which is not from Central America, but from
Trinidad, is described in this place because it is almost identical
in color and markings with flavescens. The cephalothorax,
however, is a little lower, the whole body is plainly longer and
narrower, and the legs are both relatively and actually shorter
than in that species.

The quadrangle of the eyes is equally wide in front and

behind, and occupies one-half of the cephalothorax. The
clypeus is only one-fourth as high as the anterior middle eyes.
The falces are vertical and moderately stout and are not so long
as in flavescens, being scarcely longer than the face.

The cephalothorax in our specimen is badly rubbed. It
does not show any of the yellow hairs that are seen in flavescens.
There are narrow white bands low down on the sides. The
cephalic part has two white spots on each side, one in front of
and one behind the dorsal eye. The anterior half of the
thoracic part is covered with white hairs. The clypeus has a
thin covering of white hairs. The falces are dark brown.
The abdomen has a curved white band around the anterior
end and two elongated white spots in the middle of the anterior
part, which is otherwise covered with yellow hairs. An angular
white band crosses the dorsum just behind the middle. Be-
hind this is a black space and then a wide band of yellow hairs
with a small black chevron in the middle. The posterior end
is black with a white spot in the middle and one on each side.
The legs are brown, marked with black, the first pair darkest;
all the tarsi and metatarsi are lighter colored than the other
joints. The palpi are yellow, thinly covered with white hairs.

We have a single female from ‘Trinidad, sent to us by Mr.
Broadway.

The spider is black with seyen transverse white bands,
three on the cephalothorax and four on the abdomen. The
posterior band on the cephalothorax is not so distinct as
the others. The cephalothorax has also white bands on the
sides. On the abdomen the edges of the bands are tinged
with orange. The legs and palpi are light vellow. The falces
are black.

We have two females, one from Refugio, Mexico, and one
from La Blanca, Texas, sent to us by Mr. C. H. Tyler Town-
send.

SHIRA, GEN. Nov.

Long slender spiders of medium size.

The cephalothorax is long and moderately high, and is
widest behind the dorsal eyes. The upper surface is gently’
convex, there being a slight rounded fall both in front of and
behind the dorsal eyes. After the first third the thoracic part
falls more steeply: The sides are nowhere vertical, and slant
outward more widely in the thoracic than in the cephalic part.
The quadrangle of the eyes is a very little wider in front than
behind, is scarcely wider than long, and occupies one-half of
the cephalothorax. The anterior eyes are a little separated, in
a straight row, the middle being more than twice as large as
the lateral. The second row is plainly nearer the first than
the third row. The third row is plainly narrower than the
cephalothorax at that place.

This genus is related to Anoka and Sadala, but is higher
and not so flat, with a longer cephalic part. Ashtabula, which
has the cephalic part as long as the thoracic, is still lower and
flatter.

We have only the species described below.

The cephalothorax is light yellowish-brown, with the eyes
on black spots. Two wide brown bands extend throughout its
length. The abdomen has, extending throughout its entire
length, two black bands which, when looked at closely, are seen
to be marked with fine lines and speckles of yellow. The cen-
tral region and the sides are white, covered with white hairs.
The central band has its edges serrated. The clypeus, falces,
legs and palpiare yellow, the clypeus covered with white hairs.

We have two females from Panama, sent to us by Count
Keyserling.

TULPIUS, GEN. Nov.

Small flat spiders with the first pair of legs enlarged.

The upper surface of the cephalothorax is flat and is con-
tinuous with that of the abdomen. ‘The posterior slope is
almost perpendicular and is overlapped by the anterior end of
the abdomen, which fits closely to it. The sides have their out-
line rounded, the widest point being just behind the dorsal eyes.
They are nearly vertical in front, but slant outward in the
thoracic part. The quadrangle of the eyes is about equally
wide in front and behind, is only one-fifth wider than long, and
occupies one-half of the cephalothorax. The first row of eyes

No. 1.] ATTID A OF CENTRAL AMERICA. 87

is straight, with the middle a very little more than twice the
lateral in size, all four close together. The second row is a lit-
tle nearer the third than the first. The third row is nearly as
wide as the cephalothorax at that place. The cephalothorax is
rather low. The abdomen is widest in front and tapers to the
extremity.

This genus, from the long cephalic part and the conforma-
tion of the cephalothorax and abdomen, seems to belong to the
Homalattus Group, and yet it most closely resembles Sadala, In
Sadala, however, the cephalothorax is lower, with the quad-
rangle of the eyes occupying only two-fifths of its length, and
the middle eyes of the first row are two and one-half times as
large as the lateral.

We have but one species.

male, are notched on the lower edge. (See figure.)

The cephalothorax and palpi are dark brown or black.
The abdomen varies in color from light to dark brown. It has
a blackish streak down the middle and is encircled by a band
of white hairs. Thespinneretsare black. The legs of the first

The others are pale yellow, the third and fourth having a black
line along the posterior side, which is best seen from below.
On the third leg this line is seen only on the patella and tibia,
but on the fourth it extends to the end of the tarsus. The

We have several specimens from Guatemala.

BAGHEERA, GEN. noy.

The cephalothorax is low and rather long, with the sides
vertical and nearly parallel, there being the slightest possible
widening from the front end to the middle of the thorax. The
cephalic part is a little inclined forward. The thoracic is flat,
or perhaps falls very slightly for two-thirds of its length and
then slopes abruptly to the margin. The quadrangle of the
eyes is one-third wider than long, is wider behind than in front,
and occupies two-fifths of the cephalothorax. The anterior eyes
are a little separated and form a straight row, the middle being
nearly twice as large as the lateral. The second row is a very
little nearer the first than the third. The third row is as large
as the cephalothorax at that place.

This genus is most like Anoka in general appearance and
in the contour of the upper surface of the cephalothorax, but is
quite different in the outline of the sides, which in Anoka
round out widely in the thoracic part. In Pachomius, the sides,
although they are but little widened in the thoracic part, are
not vertical, and the cephalothorax is higher and more convex
than in Bagheera.

Our specimen has been badly rubbed. The cephalothorax is
dark brown, blackish on the cephalic plate, and seems to have
been covered with yellow hairs. The abdomen is of a light
bronze-color, with an encircling white band. Under alcohol
the back is light brown with several darker brown transverse
bands which are interrupted in the middle line. The legs are
brown, the first pair darker than the others, and covered with
short yellow hairs. The third and fourth legs have the distal
end of the femur much darker than the other parts. The palpi
are broken off. The falces are dark brown.

We haye a single male from the eastern part of Guatemala.

This is a dark-colored species, with the palpi and the first
pair of legs long, and the posterior three pairs of legs yellow.

The cephalothorax is high and is widest at the dorsal eyes,
from which point there is a steep descent to the hinder margin.
The cephalic part is slightly convex and the sides are nearly
vertical. The quadrangle of the eyes is wider behind than in
front and occupies more than half of the cephalothorax. The
first row of eyes is straight. The middle eyes are about twice
as large as the lateral, and are close together, while the lateral
are separated from them. The second row of eyes is nearer
the first than the third. The third row is as wide as the
cephalothorax at that place. The falces are, like those of most
of the males of this genus, directed obliquely forward, with a
long fang, and have a vertical apophysis at the proximal end,
which terminates in a sharp tooth.

The integument is smooth and is dark brown, deepening to
black on the cephalothorax. The cephalothorax seems to have

90 PECKHAM. [Vol. 3.

been covered with white hairs. On the abdomen there is a
band of white hairs around the anterior end, which extends
on to the sides. The falces are smooth and dark brown. The
palpi are dark with a few light short hairs. The legs of the
first pair have the femur and metatarsus and the distal part of
the tibia dark brown; the other parts and all the joints of the
other legs are yellow, with a few very short fine black spines.

We have a single male from the eastern part of Guatemala.

The falces of the male are vertical, and the abdomen has

female is dark-colored, with a pattern of pale lines on the
abdomen.

The cephalothorax is high; it is slightly convex in the
cephalic part, and falls steeply from the dorsal eyes. The
sides are nearly vertical, and are plainly widest at the third
row of eyes. The quadrangle of the eyes is wider behind than
in front, and occupies more than half of the cephalothorax. The
anterior eyes form a curved row. The middle eyes are close
together and are a little less than twice as large as the lateral,
which are separated from them. The second row is plainly
nearer the first than the third row. The third row is as wide
as the cephalothorax at that place. The falces of the female
are short and vertical. Those of the male are also vertical, but
have a ridge at the outer side from which they slant toward
each other. They have a strong tooth on the front face at the
inner side, near the insertion of the fang. The fang is long.

No. 1.] ATTIDA OF CENTRAL AMERICA. 91

The male has both cephalothorax and abdomen dark
brown. The cephalothorax hasa white band around the lower
margin and some patches of white hairs are left on the other
parts. The abdomen has a band of white hairs around the
front end and two white curved transyerse bands over the dor-
sum, which grow fainter in the middle line. At each side of
these bands and at a little distance from them the color of the
integument darkens almost to black. The falces are dark red-
dish-brown and are slightly iridescent. The palpiand first legs
are reddish-brown, the legs having the femoral joints darker
than the others, and bearing three pairs of stout black spines
on the under side of the tibia. The other legs have the cox
and trochanters and, in the case of the third and fourth pairs,
the proximal ends of the femora yellow; otherwise they are
reddish-brown above and yellowish below.

The female which we have has a dark brown integument,
both cephalothoraxand abdomen showing patches of yellowish-
white hairs, which may originally have formed a complete
covering. On the abdomen is a pattern of pale bands and
streaks, which is shown in the figure. The first leg is dark
brown to the end of the tibia, the metatarsus and tarsus being
yellow. The tibia and metatarsus have strong spines. The
other legs are yellow, banded at the joints, especially in the
fourth pair, with black. The palpi are also yellow.

We have one male and one female from the eastern part
of Guatemala.

This species is easily distinguished from the others that
are found in Central America. The falces of the male are ver-
tical, and lack the vertical apophysis that usually characterizes
this genus. ‘The female differs from that of strenwus in having
the cephalothorax proportionately larger and the abdomen pro-
portionately smaller than in that species.

Legs, 4182; first pair stoutest.

This spider has a long oval abdomen, which overlaps the
cephalothorax even more than is usual in this genus, fitting
closely over the thoracic part.

The cephalothorax is high and is a little wider at the
dorsal eyes than in front or behind. The sides are almost ver-
tical. The cephalic part occupies fully three-fifths of the
cephalothorax and is level above. The thoracic part drops
abruptly from the dorsal eyes and is overlapped by the abdo-
men. The quadrangle is wider behind than in front. The
tops of the middle eyes of the first row are a little higher than
the tops of the lateral, so that.this row may be said to curve
downward. The middle are nearly twice as large as the lateral.
The second row is close to the first. The third row is as wide
as the cephalothorax at that place. The falces are short and
vertical.

The color of the body is dark brown. ‘The cephalothorax
seems to have been covered with short white hairs, and a few
slightly longer yellowish hairs grow around the eyes of the first
row. The abdomen has some short white hairs standing
out around the anterior end, but otherwise the integument is
bare, the dark brown ground color being speckled with lighter
spots and dots, with two wavy light brown streaks running
throughout the length of the dorsum. The palpus is brown,
with some short white hairs. ‘The legs are almost hairless, and
are of a light yellow color, streaked and spotted with black.
The femur of the first is darkened ; the other joints of this leg
have a black band running lengthwise along the front side, and
the tibia has a second black band on the upper surface. The
second leg has a black band running along the anterior side of

all the joints excepting the tarsus. On the third leg a similar
band extends to the extremity of the tibia, and the femur has
at the extremity, on the upper side, a three-cornered black spot.
The fourth leg has blackish bands running along both anterior
and posterior sides, and has the tarsus and metatarsus dark-
ened.

We have one female from the eastern part of Guatemala.

MESSUA, GEN. Nov.

Rather small spiders, with the cephalic plate occupying
more than one-half of the cephalothorax, and the first legs
thickened and darkened.

The cephalothorax is rather high. The cephalic part is
slightly convex and is inclined forward in front of the second
row of eyes. The thoracic part falls, distinctly, from the dorsal
eyes, being rounded in the first third, and then sloping more
steeply. The cephalothorax is plainly widest at the dorsal
eyes, narrowing toward the ends. The sides slant inward a
little in the cephalic part, and are vertical at and behind the
dorsal eyes.

The quadrangle of the eyes is plainly wider behind than
in front and occupies more-than one-half of the cephalothorax.
The width in front is scarcely greater than the length, but
behind it is one-fourth wider than long. ‘The anterior eyes are
close together in a straight row, the middle being barely twice
as large as the lateral. The second row is very much nearer
the first than the third row. .The third row is as wide as the
cephalothorax.

This genus belongs to the Homalattus Group, and agrees
closely with Zygoballus in most particulars, although its appear-
ance is different. The sides of the cephalothorax do not make
nearly so sharp an angle at the dorsal eyes as in most species of
that genus. The most marked difference between the two
genera is in the contour of the thoracic slope. In Messua it
rounds off a little in the first third and then falls more steeply,
while in Zygoballus there is one abrupt slant from the dorsal

94 PECKHAM. [Vol. 3.

eyes, nearly the whole thoracic part being overlapped by the
abdomen, this latter characteristic being entirely lacking in
Messua.

eyes of the first row. The falces are vertical and are rather
long and stout for the size of the spider.

Our only specimen has had most of the hairs rubbed
away. The cephalothorax is bronze-brown and shows patches
of white hairs. The-first legs and the falces are dark brown,
the other legs and the palpi are yellow. Under alcohol the
abdomen is white, encircled by a line of brown, and haying a
longitudinal brown band on each side of the middle. When
dry the white parts outside the brown bands are seen to be coy-
ered with white hairs, while the central white region has
patches of silvery iridescent scales.

We have a single female from Panama, sent to us by
Count Keyserling.

AKELA, GEN. Noy.

Small spiders with thickened and elongated first legs, and
long cephalic part.

The cephalothorax is rather high and is not much longer
than wide. ‘The sides widen out in a curved line from the
second row of eyes. The thoracic part is plainly wider than
the cephalic, the widest point being behind the dorsal eyes.
The cephalic part is convex but not inclined. The thoracic
rounds off from the dorsal eyes, falling a little more steeply
after the first third. The sides are vertical in the anterior

cephalic part, but begin to slant outward just behind the second
row of eyes, and in the thoracic part are plainly wider below
than on the upper surface. The quadrangle of the eyes is
equally wide in front and behind, is only one-fifth wider than
long, and occupies a little more than one-half of the cephalo-
thorax. The anterior eyes are close together in a straight row,
the middle being twice as large as the lateral. The second row
is a little nearer the third than the first. The dorsal eyes are
large and prominent and form a row which is a little narrower
than the cephalothorax. The legs of the first pair have all of
the trochanter and a part of the coxa visible from above.

Akela belongs to the Homalattus Group. Its pale body
and the thickened, elongated and dark colored first legs give
it a general resemblance to Messua, but in that genus the quad-
rangle is plainly wider behind than in front, the cephalothorax
is widest at the dorsal eyes, and the sides are vertical. It does
not resemble any of the other genera of the group.

The cephalothorax is about as long as the abdomen, which
it overlaps.

The clypeus is only one-fourth as high as the anterior

above, and are divergent and moderately stout and long.

The cephalic part is very dark brown, contrasting with

the thoracic, which is light reddish-yellow, with darker rays
diverging from just behind the dorsal eyes. The abdomen is
very pale yellow with darker streaks, which are made up of
fine disconnected lines. The falces are dark brown. The palpi

are medium brown, except the tarsi, which are white. The legs
of the first pair are of a dark brown, except the patella and the
tarsus, which are white with a satiny lustre. The other legs
are very pale yellow, like the abdomen.

We have a single male from Guatemala.

The cephalothorax is high and is a little longer than wide.
It is widest at the anterior end, contracts a little in the cephalic
part, and widens again in the thoracic. The sides slant inward
from the upper surface to the lower margin. The cephalic
part slants very abruptly forward. The thoracic part has, just
behind the dorsal eyes, a crescent-shaped plate which slants
backward, and then falls steeply. The highest point is at the
dorsal eves.

The anterior eyes are large and form a straight row, the
lateral being about two-thirds the size of the middle. The
middleeyesaresubtouching while the lateral are a little separated

to be half-way between the first and the third, but from the
side it appears to be nearer the third than the first.

The dorsal eyes form a row as wide as the cephalothorax
at that place, and stand out prominently, marking the hinder
corners of the cephalic plate.

The quadrangle of the eyes is wider in front than behind,
is one-third wider than long, and occupies one-half of the

Under alcohol the spider presents the appearance that is
given in the drawing, the abdomen haying a dark region on
each side, broken by white spots and bands, and a pale band
down the middle which widens out behind. When dry the
cephalothorax is seen to have, on the cephalic plate, and on
the crescent-shaped part of the thorax, a covering of iridescent
scales, while behind and on the sides it is of a bright cinna-
mon-brown, owing to the color of the hairs. The anterior sides
have wide short bands of white hairs and there is a central
white spot on the posterior thoracic part. The sides of the
abdomen are of a bright rich cinnamon-brown. A central
spot in front, two oblique bands on the anterior sides, two
large rounded spots on the middle sides, and two smaller spots
which mark off the brown region at the point where the central
band widens, are all of the purest white. The central band,
which widens behind more in some specimens than in others,
is covered with brilliant iridescent green scales.

The legs are of a pale brown, without many hairs.

We have seven females from Panama.

This makes the second species of this genus Sidusa, de-
scribed in our paper on the Homalattus Group, p. 175. It
strikingly resembles the type, gratiosa, which is found on the
Amazon, both in shape and in its iridescent coloring.

LYSSOMANES, HeEn‘z.

After more extended study of this genus, the species of
which are found in North, Central and South America, we have
concluded that our former division into two sub-genera is un-
desirable. Due to the fact that the color fades rapidly in
alcohol, the species are difficult of determination. The distinc-
tive points must be looked for in the ornamentation of the
legs, the modification of the falces, the variation in size, and,
most important of all, in the reproductive organs. So far we
have seven species from North and Central America, four rep-
resented by both males and females, three by males alone, and

98

one by the female alone. The following table will be useful
in distinguishing the species, so far as the males are concerned.
As to the females, they resemble each other so closely (except-
ing that patens has the legs 1243 instead of 1234), that they can
only be distinguished by the epigynes.

The male is exceedingly slender. The eyes of the first
row are twice as large as those of the second, the second row
being wider than the first. The falces of the male are long
and obliquely directed, diverging after the first third, with a
long fang. The palpus has the tibia longer than the patella
and these two joints together nearly as long as the tarsus.
There is a stiff bunch of hairs on the upper side of the distal
end of the tibia. The distal half of the metatarsus of the first
leg is slightly darkened, and has a very scanty fringe of hairs
on each side.

The female has the falces vertical and stout, with short
stiff hairs growing over the front face. The fang is long and
slender. The clypeus is higher than in the male.

The spider is pale yellow with a central dark line on the
thoracic part. There are some red and white hairs left on the
cephalic part. The clypeus is covered with red hairs in the
male and with white hairs in the female. The first eyes are
white, the others black.

We have a male and a female from Panama, and a female
from British Honduras.

The eyes of the first row are three times as large as those
of the second and area little nearer together. ‘The falces are
long, horizontal, and diverging, with several small teeth along
the inner edge. The fang is slender and curved, and is three-
fourths as long as the falx. The palpus has the tibia plainly
longer than the patella, and the tibia and patella together are
nearly as long as the tarsus.

The spider is pale yellow, the abdomen and legs being a
shade lighter than the cephalothorax and falces. The cepha-
lothorax has a dark central spot on the thoracic part, and on
the abdomen are two longitudinal black bands extending
to the end of the spinnerets. The metatarsus of the first leg
has the distal third darkened and fringed on each side with
stiff dark hairs. The eyes of the first row are white, and
those of the others black.

We haye a single male from Panama, sent to us by Count
Keyserling.

projections at the distal end, consisting of a strong curved tooth,
or apophysis, on the inner side, and a stout notched apophy-
sis at the outer corner. The fang at first starts at a right
angle to the falx, and on this part, underneath, thereis a heavy
curved tooth, or apophysis. It then bends so as to run in line
with the falx, being about three-fourths as long. The palpus
has the tibia longer than the patella, and these two joints
together nearly equal to the tarsus.

The spider is pale yellow with a dark central longitudinal
line on the thoracic part. The distal third of the metatarsus
of the first leg is very slightly darkened, with a light-colored
scanty fringe of hairs on each side. The eyes of the first row
are white, the others black.

We haye a single male from British Honduras.
