NEW HA.MFKHIKE. 



By Clarence M. Weed, D. Sc. 



This paper is based on the collections made during 1891 and 1892 

 by myself at Hanover, N. H., and vicinity, together with a number 

 of other harvest-spiders collected in different parts of the State by 

 two of my students, Messrs. W. E. Britton and F. W. Howe. I 

 have included also a number of specimens kindly collected for me at 

 Hartland, Vt., fourteen miles south of Hanover, by Mr. B. P. Rug- 

 gles. Only six species have as yet been found in the State, but it is 

 probable that several others will be added when the northern coun- 

 ties, the White Mountains and the sea-coast regions are more thor- 

 oughly explored for them. 



The measurements of the various species, except P. cinereum, which 

 are given below, are taken from New Hampshire specimens. 



Family PHALANGHD.E. 

 Subfamily Phalangiin.e. 



Members of this subfamily are Arachnids having the body com- 

 posed of a single piece, and long, slender legs. The teguments are 

 not coriaceous, though often quite solid. The segments are only in- 

 dicated by strite, which are often obsolete. There are five ventral 

 abdominal segments; a single anal j)iece, and two distinct lateral 

 pores on upper margin of cephalothorax. The maxillary lobe of 

 the palpus has two tubercles, and the epistoma is in the form of an 

 elongated triangular plate. 



The three genera found in New Hampshire may be distinguished 

 as follows : 



I. — First joint of iiiiUHlihlcs witli a tootli on ventral stirfat'c near base. 



A. — Maxillary lobes of second pair of legs with :i large base, imj)re.sse(l, straight 

 and elongated, not attenuate, but ratiier a little enlarged from the base 

 to the apex and very obtuse ; elaw of palpus denticulati.'...I..i«bminin.
