266 CLARENCE M. WEED. 



This species is quite rare in New Hampshire. Several specimens 

 were found under boards in a pasture at Hanover during August, 

 and one specimen was collected during the same month at Hartland, 

 Vt., by Mr. B. P. Ruggles. No females have yet been observed 

 here, this sex of the species being nearly always rarer than the males. 



This species is reniarkable for its small body and exceedingly long 

 legs. It is an out-door form, living in woods, and especially abounds 

 in some rocky regions. A few years ago I found it very abundant 

 in the rocky ledges of southern Illinois. The males appear to be 

 four or five times as numerous as the females. 



In my early studies of the harvest-spiders I mistook this species 

 for L. nigropalpi Wood, but as soon as I received a specimen of the 

 latter I saw the error. In the " American Naturalist' ' for Septem- 

 ber, 1890, I report having received one specimen of L. longipes from 

 Alabama, but a more critical examination shows this to belong else- 

 where. 



The more southern forms of this harvest-spider have the legs con- 

 siderably longer. In Ohio and Illinois the second pair of the male 

 ranges from 82 mm. to 99 mm.

Male. — Body 3.1 mm. long, 2.4 mm. wide; palpi 2.7 mm. long. Legs: first, 

 26 mm.; second, 48 mm. : third, 26 mm.; fourth, 37 mm. Dorsum smooth, finely 

 granulate: clear reddish brown, with no markings, except occasionally a faint 

 indication (shown by a slightly darker shade) of the usual central dark mark- 

 ing. Eye eminence rather prominent, slightly constricted at base, black above, 

 canaliculate, with a regular curved .series of small, acute, black spines over each 

 eye. Mandibles whitish, tips of claws black. Palpi slender, light brown, with 

 femur and patella dusky ; finely pubescent, with a sub-obsolete row of minute 

 dark tubercles on the inner ventro-lateral surface of femur, and another row on 

 the inner ventro-lateral surface of tarsus: joints slightly arched. Ventrum with 

 (ioxie, including the membranous distal lateral tips, and generally the trochanters, 

 vermilion-red. Legs with proximal portions light brown ; distally dark brown 

 or blackish. Shaft of genital organ nearly straight, slender, flattened, canalicu- 

 late ; distal portion very slightly expanded, then slightly contracted, and again 

 expanded into a half spoon-shaped portion, and terminating in a small acute 

 point. 



Female. — Diflers from the male in having a larger, rounder body, and in the 

 color of the dorsum, which is brown, with a rather distinct, darker central mark- 

 ing and numerous whitish spots arranged more or less transversely. In some 

 specimens the central marking is sub-ob.solete. Apical rings of ovii)ositor white. 



This species has been collected repeatedly at Hanover during
