82 The Graspedosomatidae of North America 



strongly crassate; fourth joint less crassate, the others nearly normal, except 

 that all are hirsute; claw very small, but larger than on the second legs. 



Legs 4-7 not specially modified. 



Male genitalia (figs. 186-187) consisting of an anterior lamina deeply bifid 

 at apex, the divisions subequal, curved backward; anterior lamina simple, 

 narrow, subequal in length to the other; a median subclavate process arising 

 from the pedigerous lamina. 



Ninth legs of male (figs. 186-187) two jointed, the basal joint large and 

 bulbous at base, gradually attenuate distad into a point, subequal to the geni- 

 talia in length ; second joint broadly oval, attached by a narrow base to the 

 outer side of the first joint; outer face of second joint somewhat flattened, 

 hirsute externally (anterior face) and distally, also with a few papillae. 



Tenth legs of male with the coxse ( fig. 185 ) grea.tly enlarged and with an 

 irregular mass of membrane or hardened secretion attached to the ventral 

 side; other joints normal but reduced in size. 



Color dark horn-brown, lighter below. The shade varies, some specimens 

 being much lighter than others. The darkest color is upon the head and the 

 exposed portion of the anterior subsegments, giving the animal alternate bands 

 of darker and lighter brown, if examined more closely. Last segment and 

 anal valves dark. Excepting the dark band the segments are spotted and 

 mottled with light brown or whitish. A fine median line pale or whitish. 

 Feet pale, the distal joints darker than the proximal. Antennae dark, each 

 joint finely ringed with white at base. 



Length about 8 mm. ; width .65inm. 



Habitat: We have collected about 80 specimens on the 

 north shore of Long Island, New York, May, 1893, at two sta- 

 tions about seven miles apart, Centreport and Cold Spring. 



The habitat was in both cases quite the same, among rotting 

 leaves on a heavily wooded hillside where the ground was 

 springy and moist all the j'ear. The Cold Spring station is near 

 the building of the New York State Pish Commission. Of the 

 nearly 80 specimens but two were males, hence the specific name. 

 Specimens were not abundant and several hours were spent col- 

 lecting them, in the hope of finding more males, so that the ma- 

 terial for study might be more abundant, the animal being so 

 small that nothing can be made out with accuracy without dis- 

 section. 



The species differs from U. iuloides in being slightly larger, of 

 dark color, in the better development of the eyes, and in hav- 

 ing the third joint of the antennae longer than the fifth.
