THE CANADIAN ENTOMOLOGIST. 21 



distinct suture ; terminal portion rectangular, with the anterior margin 

 slightly convex. Second, third and fourth segments linear, fifth much 

 wider. The anal piece consists of three parts: the superior part (i)ygidium) 

 semicircular, the two lateral anal valves small and triangular; the anal 

 sternite represented by a small dark spot scarcely hardened. Between the 

 ends of the fifth ventral and eighth dorsal segments there is on each side 

 a small, irregularly shaped sclerite. The hardened parts are brown, with 

 the surface slightly roughened by minute tubercles ; certain areas are, 

 however, armed with larger tubercles less thickly placed, as follows : The 

 entire cephalothorax, except the area between the eye tubercle and the 

 transverse groove ; a large quadrate area on the anterior part of the large 

 dorsal plate, indistinctly divided into three parts ; two transverse areas 

 behind this ; narrow transverse areas on the sixth, seventh and eighth 

 dorsal segments ; the entire surface of the pygidium, and the posterior 

 part of the first ventral segment. 



Coxae of nearly equal length, trochanters globular, both are dark brown 

 and armed with short black spines. Base of femur white and unarmed, 

 rest of femur, patella and tibia brown, and armed with short acute peri:)en- 

 dicular spines and long slender hairs, which in their basal half are at right 

 angles to the segment, and in their distal half bent forward and somewhat 

 matted together. The other segments pale, thinly clothed with slender 

 oblique spines and very fine appressed hairs. Each tibia armed at the 

 tip above with a short, stout, slightly curved, tooth-like spine. Tarsal 

 claws unarmed. 



Palpus long and slender, sparsely clothed with short, erect setse j 

 trochanter armed below with three' longer recurved setae ; tarsus slightly 

 clavate and more thickly clothed with setae than the other segments. 

 Chelicerae light gray, the claw armed with a series of fourteen teeth, of 

 which the terminal two are the largest ; the opposing figure armed with 

 about ten similar teeth. Preepistome broad, convex and strongly 

 chitinized, epistome produced into a sharp vertical ridge. Endites of the 

 palpus white, triangular, with the outer margins slightly convex. Endites 

 of the first pair of legs with a chitinized lateral border, curved and enlarged 

 distally, inner portion white, with the anterior margin convex ; situated 

 between them is a small semicircular sclerite, which" seems to represent the 

 sternum. Coxse of the second pair distant from sternum and not provided 

 with endites. (Fig. i.)
