DESCRIPTION OF GENERA AND SPECIES. 145 
at the face. The color of the cephalothorax is uniform orange brown, with a light band, 
heavily pubescent, on the extreme margin, The skin is glossy, but little pubescent. The 
legs are orange to orange yellow, with orange brown annuli at the tips of the joints, and 
median annuli along femurs-I and IT. The color of the tibia is rather lighter than that 
of the femur, and the metatarsus and tarsus still lighter yellow. The tibia of leg-II is 
curved, thickened about the middle, and with a triple row of short, black, toothed clasping 
spines upon the inner side. The spines upon the femora are shorter; those upon the tibia 
of leg-I are long, yellowish brown, with dark bases. The cox of leg-I has upon the 
side next leg-II a short, curved brown spur, curved toward the face; and coxse-II has at 
the base near the articulation of the sternum a slight conical process. The palps are as in 
Plate I., Fig. le, 2b. The abdomen is a long oval, colored and marked upon the dorsum 
with a folium not greatly differing from that of the female. 
Disrrrsurion; As Marmorea is widely distributed throughout Europe and the Amer- 
ican specimen is found in most parts of the United States, the species is thus seen to have 
an extended distribution. I haye collected it from New England southward to Florida, 
westward through Pennsylvania, Ohio, Illinois, Wisconsin. It is found in Arizona, but I 
have as yet received no specimens from the Pacific Coast.

Fremate: Total length, 15 mm.; cephalothorax, 7.5 mm. long, 6 mm, wide; abdomen, 
12 mm, long, 8 mm. wide. This is one of our largest indigenous species, and varies much 
in size from the above length and upward to adult females of 10 mm. long. It is especially 
distinguished by great differences in color at different stages and among different individ- 
uals, as illustrated Vol. II., Plate I., p. 48. 
CrrHatorHorax: A rounded oyal or cordate, truncated and indented at the base; corselet 
flat on top, the fosse a deep transverse slit; cephalic suture sufficiently marked, corselet 
grooves rather indistinct; color brown, with a yellow marginal band on the dorsum, passing 
upward to the sides of the caput; head lowly arched ; face depressed, wide, quadrate, with 
gray pubescence. The sternum is shield shaped, dark brown, the median band of lighter 
color; sternal cones marked; labium blackish brown, lighter at the tip, as are also the 
maxillse, which are longer than or as long as wide. 
Eyes: Ocular quad on a well rounded prominence, the front wider than rear and 
narrower than sides; MF separated by 1.5 to 2 diameters, somewhat larger than MR, 
which are separated by one diameter or more; side eyes on tubercles, separated by about 
the diameter of SR, which are smaller than SF; MF divided from SF by about 1.5 the 
area of MF, or say 2.5 times their interspace; clypeus height about two diameters or more 
of MF, and with marginal row of strong yellow hairs. The front row recurved and shorter 
than the procurved rear row. 
Lxes: 1, 2, 4, 3; strong, stout, not long for the size of the species, abundantly pro- 
vided with grayish yellow hairs and bristles and yellow spines, which are dark brown on 
the basal half; color yellow, with bright brown apical tips, patelle entirely brown, feet 
brownish black. Palps light yellow, without annuli, thickly provided with strong yellow 
spines and bristles. Mandibles strong, conical, arched at the base, and swollen on the 
outside at the articulation with the ahpnene: 
1 Abbot’s drawing of this Failed in he MSS. in eaneinnient Library of the Brit. Mus. Nat. Hist. 
appears: to be BE, trifolium Hentz; but there is enough doubt as between this and BE. insularis Hz. to 
justify leaving the name thus.
