'74 The Grasjjedosomatidae of North America. 



Seventh legs of male with joints of similar proportions; on the side of the 

 proximal end of the fourth joint a long, nearly cylindrical process, at the end 

 with four large teeth, between which its surface is beset with small cones. 

 The distal end of the coxa has a rounded protuberance covered with small 

 knobs. This protuberance is on the inferior-posterior surface of the coxa, 

 and it appears to fit against the anterior of the two pairs of genitalia. 



Tenth legs of male with nearly the same proportions as the seventh, slightly 

 more slender, coxse closely approximate, each produced into a protuberance 

 next to the median line; the protuberance is distally of soft tissue, and very 

 irregular in shape and size. Seventh joint roughened below with hooks. Claw 

 with two small secondary claws on superior edge. 



Eleventh legs of male with similar proportions ; third joint inferiorly and 

 proximally with a cylindrical process directed mesad. Seventh joint with 

 hook- like rough enings more confined to distal portion; two secondary claws. 



Twelfth legs of male slightly longer and more slender than the others. Sev- 

 enth joint as for eleventh legs. Two secondary claws ; inferior surface of 

 coxae with small knobs. 



The legs of females are in a general way similar in size and shape to those 

 of males, but the anterior are more slender, and all are destitute of the pecu- 

 liar knobs, processes, and protuberances. 



The normal legs of the body are more slender than the anterior pairs. The 

 bayonet-like structures of the seventh joint gradually decrease in number, 

 and disappear at the fortj^-fifth pair. The surface of the coxae of all the legs 

 is roughened with small conical knobs, as is also the surface of the pedifer- 

 ous laminae. 



In the inferior groove of the claw of all the legs of this species is a very 

 delicate hair extending considerably beyond the claw, to which it lies closely 

 appressed. We have not been able to find any similar structure in other species. 



Color obscure horn-brown, w'ith dark brown points, especially on the ex- 

 posed posterior portions of the segments; ventral portions mottled. Proximal 

 joints of legs paler, the distal dark brown; antennae fuscous. Penultimate 

 segment pale, the last segment dark. 



Length of large specimen 18 mm. ; width 1.6 mm. 



Habitat — Centra.1 New York. We have collected about 

 100 specimens from the following localities : — Syracuse, James- 

 ville, Onativia and Marcellus, Onondaga countj'^; Wolcott, Wayne 

 count}^; Farmington, Ontario county. At Marcellus several in- 

 dividuals were found under the loose bark of a fallen butternut 

 tree (^Juglans cinerea). All the other specimens were found 

 among leaves and rotting vegetable matter in moist woods. 



It gives us great pleasure to name this species for our friend^ 

 Prof. J. T. Fischer, of S^^racuse Universitj' , whose keen powers 

 of vision and lively company contributed greatl}^ to the success 

 and pleasure of many collecting expeditions in central New York.
