DESCRIPTION OF GENERA AND SPECIES. 247 



Genus LARINIA, Simon, 1874. 



In Larinia' tlie cephalothorax is oval, with decided corselet grooves and longitu- 

 dinal fosse. The inidrear eyes are closely approximated, almost contingent; the interval 

 which separates them from the siderear eyes is much greater than that which divides the 

 midfront pair. The midfront eyes form a straight, or almost straight, row, arranged at 

 almost equal distances from one another ; the distance between the midfront and sidefront 

 being sliglitly the greater. The mandibles are perpendicular ; the sternum is longer than 

 wide ; the labium and maxillre are as in Epeira. The abdomen is much longer than 

 wide, oval in shape, attenuated at the two extremities, marked by longitudinal bands. The 

 palps are as in Epeira. The legs in order of length are 1, 2, 4, 3 ; more or less robust ; 

 provided with four pairs of sjiines on the femora, tibife, and metatarsi ; the tibiae of the 

 first and second paire are equally slender ; the thighs are without hairs. The superior 

 tarsal claws have nine or ten denticulations, of which the first are much longer than the 

 others, which are about equal. The skin is almost always smooth, although covered with 

 colored hairs and pubescence, as in Epeira.

Female: Total length, 7 mm.; cephalothorax, 3 mm. long, 2 mm. wide; width at face, 

 1 mm. ; abdomen, 5 mm. long, 3 mm. wide, less than 1 mm. at base. 



Cephalothor.v.x : A long oval, high and somewhat peaked at the fosse, which is a 

 longitudinal slit ; squarely truncate behind ; the corselet grooves distinct ; cephalic suture 

 pronounced ; the caput slightly depressed and gently arched from fosse to ocular space ; 

 face sufficiently wide, aljout, or a little more than, one half the greatest width of the 

 cephalothorax ; color dull yellow ; slightly pubescent, except at the face, where there are 

 tufts of strong, whitish, gray bristles. 



Sternum: Cordate, longer than wide, in the proportion of five to four; elevated and 

 arched in the middle ; with sternal cones ; the apex triangular, the anterior and middle 

 part indented, and of about equal width ; color blackish brown, with an irregular median 

 band of yellowish ; scantily provided with bristlelike hairs on the margin. Labium with 

 a short compressed sliank ; tip at base wider than high ; subtriangular ; of a light yellow 

 brown color. IMaxillse somewhat longer than wide ; the shank slightly compressed ; the 

 apex rounded and thickened, and obtusely triangular at the tip ; a few short, curved, 

 stubby bristles. 



Eyes : Ocular quad elevated in front, the rear eyes seated upon the base of the eleva- 

 tion ; the quad decidedly wider in front than rear ; ^MF somewhat larger than MK, whicli 

 are separated by less than a radius, indeed are almost contingent ; distance between MF 

 and SF about 1.3 the Interval of MF, or less than the area thereof. Side eyes on slight 

 tubercles, with blackish bases; barely contingent; subequal, but SF apparently slightly 

 larger ; the space between MR and SR decidedly greater than between MF and SF, ancl 

 equal to about 1.5 the area of MR; the front eye row slightly recurved, rear row prii- 

 curved, in this respect resembling Epeira ; clypeus height ec^ual to about one diameter MF. 



Legs: 1, 2, 4, 3. Color uniform yellow; short, rather stout, well provided with hairs 

 and bristles, and rather simrsely with thin, yellowish spines; tibia and metatarsus of leg-I 

 about equal in length ; palps colored as the legs ; mandibles conical, not receding, yellow. 



Abdo.mex : Ovate, compressed at the base to an obtuse point, which overhangs the 

 cephalothorax ; rounded at the apex, where it diminishes in width, but is not compressed 

 to a point, as at the apex ; dorsum evenly arched to the apex, which slightly overhangs 

 the si)innerets ; color dull yellow ; rather thickly coated with yellowish white hairs ; a 

 median band of lighter yellow, and of almost equal width throughout, passes from base to 



' f give substantially Simon's diagnosis of this genus.
