The cephalo-thorax is compressed before, depressed and rounded on the sides, hairy, with 
a narrow indentation in the medial line of the posterior region ; it is of a dark-brown colour, 
a broad, red-brown band extending along the middle, the anterior extremity of which is 
enlarged and comprises two parallel, oblong, dark-brown spots, and above each lateral margin 
there is a narrow, longitudinal, red-brown band, several obscure lines of the same hue con¬ 
verging from these bands towards the middle. The falces are powerful, conical, and armed 
with teeth on the inner surface; the maxillae are strong, and obliquely truncated at the 
extremity, on the inner side; the lip is nearly quadrate ; and the sternum is of a short, oval 
form. These parts are of a red-brown colour, the falces and lip being the darkest. The 
lateral eyes of the four constituting the anterior row are somewhat smaller than the inter¬ 
mediate ones. The legs are robust, provided with hairs and black spines, and of a reddish- 
brown colour, the thighs, which are the palest, being obscurely marked with annuli of a darker 
hue. Like the other species of the genus, this spider has the superior tarsal claws curved and 
pectinated, and the inferior one inflected near its base. The palpi have a reddish-brown tint; 
the digital joint is the darkest, and, in common with the female Lycosa , is terminated by a 
curved, pectinated claw. The abdomen is oviform, densely covered with hairs, rather broader 
at the posterior than at the anterior extremity, convex above, projecting over the base of the 
cephalo-thorax; it is of a yellowish-brown colour, with a large, brownish-black, angular mark 
on the upper part, at the anterior extremity; to this mark succeeds an oblong, dark, yellowish- 
brown space, obscurely bordered by a brownish-black line, having an angular projection on 
each side near its pointed termination, and between it and the spinners there is a series of 
black, angular lines, which have their vertices directed forwards, and are intersected by 
transverse, curved lines of a yellowish-brown colour; the lines of both series are enlarged at 
their extremities, and these enlargements form two rows of black and yellowish-brown spots, 
disposed alternately, which converge to the spinners ; brownish-black spots occur on the 
sides, and, more sparingly, on the under part; the sexual organs are glossy, of a dark, reddish-
