Spiders captured in Canada. 31 
pair the longest, then the first, third pair the shortest ; they are 
of a dark yellowish brown colour, the metatarsi and tarsi being 
the darkest, and the coxe are dark brown on the under side. The 
palpi resemble the legs in colour. Abdomen thickly covered with 
hairs, oviform, rather larger at the posterior than at the anterior 
extremity, convex above, projecting over the base of the cephalo- 
thorax ; the upper part is brown with a yellowish tinge, a brown 
rhomboidal band extending from the anterior extremity along the 
middle, about half-way towards the spinners ; on each side of the 
broadest part of this band is a small mdentation surrounded by 
yellowish brown hairs; sides and under part yellowish brown, 
spotted with brown, the spots being much the most numerous on 
the former. Orifice of the sexual organs bisected by a longitu- 
dinal septum, which, with the margins, is reddish brown. Plates 
of the spiracles brown. 
The male is smaller and slenderer than the female, and its 
legs, palpi, mandibles, maxille and lip are paler. The radial 
joint of the palpi is rather longer than the cubital; the digital 
joint is of an oblong-oval figure, convex and hairy externally, 
concave within, at the base, which concavity comprises the palpal 
organs; they are neither highly developed nor very complicated 
in structure, the upper part bemmg prominent and projecting a 
process which curves along the inner side and terminates in a 
point ; their colour is reddish brown with yellowish brown inter- 
mixed. The compact extremity of the digital joint is densely 
covered with long, fine hairs on the under side. 
I have much pleasure in dedicating this fine species to Charles 
Cardale Babington, Esq., M.A., St. John’s College, Cambridge, 
to whom I am indebted for an extensive and highly interesting 
collection of British spiders. 
2. Lycosa propinqua. 
Length of the female 3 an inch; length of the cephalo-thorax 
43; breadth ;%; breadth of the abdomen }; length of a posterior 
leg 2; length of a leg of the third pair 5. 
Mandibles powerful, conical, vertical, and armed with teeth on 
the mner surface: maxille straight, gradually enlarged to the 
extremity, which is obliquely truncated and fringed with long 
hairs on the inner surface: lip nearly quadrate, being rather 
broader at the base than at the apex: -sternum heart-shaped : 
these parts are dark brown, the extremities of the maxille and 
hp being tinged with red. Cephalo-thorax hairy, compressed 
before, depressed on the sides and at the posterior part, with fur- 
rows diverging from the middle towards the lateral margins, and 
a narrow indentation in the medial line of the posterior region ; 
it is of a dark brown colour, with a broad grayish band extend-
