FEMALE: This species closely resembles E. sclopetaria and E. strix. The specimens differ 

 much in their dorsal markings, as well as in their general colorings, as illustrated in Plate 

 III., Figs. 8a-8f. Sometimes the specimens are quite light, at other times dark brown or 

 black, and among northern individuals yellow bands are mingled with the dark colors. The 

 specimens collected in the North appear to be colored more brilliantly than those found in 

 the South. Total length of adults, from 13 to 8 mm. 



CEPHALOTHORAX : 5 mm. long, by 4 mm. wide, 2 mm. at the face; a rounded oval, not 

 high, flattened at the summit; the fosse a deep semicircular pit; skin glossy, thickly covered 

 with grayish white hairs upon the summit and the entire surface of the caput, and a line 

 of similar hairs around the margin of the corselet. The head is somewhat depressed, the 

 face with heavy gray eyebrows. The sternum shield shaped, longer than wide; dark or 

 dark brown, covered with grayish yellow hair. The labium is semicircular ; dark brown at 

 the base and yellow at the tips, as are also the maxillae. 



LEGS: Order, 1, 2, 4, 3; femora, orange yellow to brown at the base, blackish at the tip; 

 the patella and tibia similarly colored, the latter with a darker ring at the tip and a median 

 annulus. The metatarsus and tarsus are yellow, the former with dark annuli at the tip and 

 midway. The feet are blackish brown ; strongly armored with yellowish gray hairs and 

 bristles and dark spines, which are intermingled with shorter yellow ones, dark at the base. 

 The palps are armed as the feet. The maxillse are parallel, conical, glossy, blackish brown, 

 and hairy. 



EYES: Ocular quad upon an eminence, the rear eyes set at the base thereof; length 

 and width about equal ; wider in front than behind ; MF separated by about two diameters, 

 MR by about one ; middle eyes not greatly differing in size. Side eyes not contingent ; set 

 upon tubercles; SF the larger, and separated from MF by about 1.3 the area of the latter. 

 Front row recurved; rear row, which is the longer, procurved. The clypeus removed from 

 MF by 1.5 the diameter of the latter. 



ABDOMEN : A long oval ; 8.5 mm. long, 6 mm. wide, across the base ; narrowing towards 

 the spinnerets; not greatly arched; narrowing to the apex, which is about as thick as the 

 base. The dorsal folium resembles that of Sclopetaria and Strix, but lacks the strong mar- 

 ginal lines of long hairs on the former. The color is dark brown, with a yellow herring 

 bone pattern in the centre. A lance head figure of brown, with yellow margin, divides the 

 base, passing along the front. The margins of the folium are deeply scalloped ; on either 

 side a broad undulating band of yellow, followed along the sides by a band of dark brown ; 

 the venter a dark brown trapezoidal band, surrounded by yellow lunettes resembling Strix 

 and Sclopetaria. The epigynum (Plate I., Fig. lla) has a short spoon shaped scapus, which 

 in mature specimens separates it from Strix and Sclopetaria. 



MALE : Total length, 9 mm. ; abdomen, 6 mm. long by 4 mm. wide ; cephalothorax, 5 mm. 

 long by 4 mm. wide. In appearance (Plate III., Fig. 9) it does not widely differ from the 

 female. The cephalothorax is brown shading off into yellow, pubescent, with a narrow, 

 hairy ring around the margin of the corselet; the caput covered with hairs longer and 

 more numerous on the edges, forming a decided eyebrow. The legs are yellowish brown,
