DESCRIPTION OF GENERA AND SPECIES. 189 
Fremarre: Total length, 14 mm.; abdomen, 9 mm. long, 7.5 mm. broad; cephalothorax, 
6 mm. long, 5— wide; face, 2 mm. wide. The colors vary much. I have collected speci- 
mens in England, Scotland, and Wales haying the bright yellows shown in the plates; but 
haye taken others in Norway with dark or blackish folial colors. 
CrpHaLtotHorax: Corselet oval; color orange brown, with a yellow marginal band, 
lateral stripes; fosse, a longitudinal slit, with deeper indentation in the centre; corselet 
grooves sufficiently distinct; cephalic suture deep; caput depressed at the face; slightly 
pubescent. Sternum cordate, hairy, with sternal cones, elevated in the centre; brownish 
color. Labium and maxillz as in Epeira; color brown, with yellowish tips. 
Eyes: Ocular quad elevated; wider in front than behind; eyes not greatly different in 
size; MF separated by about two diameters; MR by about one. Side eyes on tubercles; not 
contingent; SF (round) larger than SR (oval), somewhat smaller than MR; separated from 
MF by about 1.3 area of the latter. Front row slightly recurved, rear row longer and pro- 
curved ; height of clypeus about two diameters MF. 
Lures: 1, 2, 4, 3; orange yellow, with brown annuli at tips of joints; well armored with 
gray bristles and yellow and brown spines on metatarsus; spines with black bases; palps 
and mandibles orange yellow, the latter conical and parallel. 
AxspomEn: Triangular ovate; longer than broad; dorsum arched to the apex and some- 
what flattened ; apical wall high, perpendicular, and almost as thick as the base. The color 
varies from velvety brown to yellowish gray, with numerous yellowish white bristlelike 
hairs. Between the shoulder humps on the basal front is a yellow cruciform marking, 
interrupted in its members at their crossing. The folium has an interrupted scalloped 
margin of yellow receding towards the apex. On the sides are lateral lines of yellow, and 
longitudinal ribbons of yellow mottled with brown. Further down the sides are dark 
brown, covered thickly with yellowish hairs. The ventral pattern is a broad rectangular 
ribbon of brown, lighter in the centre, and flanked on either side by a broad yellow ribbon, 
which extends with an interruption around the brown spinnerets. The epigynum (Plate 
XI., 10, 10d) has a long wrinkled scapus, broadest at the base, but somewhat diminished 
towards the tip, which is rounded and spooned. 
Mare: I have no male of this species from America, and the only specimen in my 
collection from Ireland (Mr. Thomas Workman) is much damaged. I have therefore given 
in Plate XI., Figs. 11, lla, Blackwall’s figure of this sex, correcting, however, the defective 
drawing of the second leg, whose tibia is more robust, and provided with two parallel rows 
of short, strong, black clasping spines on the anterior surface. The male bears a marked 
resemblance to the female, but is smaller, 8 mm. , 
Distripution: I have specimens from Minnesota (Mr. Ainsley), Wisconsin (Professor 
Peckham); Dr. Marx has specimens from Vancouver’s Island on the west and Newfoundland 
on the east. It is not improbable that this species has been introduced from Europe by 
immigrants, inasmuch as so few examples have been reported. It, however, is fixed upon 
our shores, and may be expected to occur along the northern tier of States and Territories 
from ocean to ocean, and in the future will doubtless be distributed southward at least to 
the semitropical States. E. diademata is one of the longest and best known species of 
Europe, where it is common, and is known as the “Cross Spider.” It is probably found in 
the contiguous parts of Africa and Asia. It has been the subject of numerous studies by 
anatomists and histologists, having been generally accepted as the representative type of 
Orbweayers. 
No. 47. Epeira Peckhamii, new species. Plate XVIII, Figs. 5, 6. 
Femate: Total length, 6 mm.; abdomen, 4.5 mm. long, 3.5 mm. wide across the base ; 
cephalothorax, 2.5 long, 2 wide. On my first casual study of this species it seemed to me a 
Zilla, and is so named in the plate, which was printed before closer study disclosed my error. 
CrrHALoTHoRAX: Corselet oval, almost as wide as long; rounded at the edges; elevated 
in the centre; fosse a deep circular pit; corselet grooves indistinct; cephalic suture well
