The Gras^oedosomatidse of North America. 87 



Legs rather slender, moderately hirsute, the coxae approximate, reticiilate- 

 areolate, especially on posterior legs. 



First legs of male (fig. 198) slender, apparently of the usual form, our 

 specimen somewhat broken and distal joint lost. 



Second legs of male ( figs. 199-200 ) more slender than the first ; coxa pro- 

 duced from the anterior face into a blunt process curved backward ; the process 

 is partly concealed by a tuft of long hairs which arise from the coxa behind 

 the process, extend distad and mesad and are curved around the process; third 

 joint very long, thickly tuberculate on the middle of the ventral face. 



Third legs of male (figs. 201-203) with coxa much enlarged and produced 

 into conic processes, clothed at apex with a tuft of long hairs ; both surfaces of 

 the joint are sparsely hirsute with shorter hairs; other joints not specially 

 modified, except that the distal joints are more hirsute; claw normal, equal 

 to that of the second legs. 



Sixth male legs (fig. 206) with coxa slightly enlarged, the meso-distal cor- 

 ner prominent, clothed Avith long hairs. 



Seventh male legs (figs. 207-209) with coxa greatly enlarged; on the mid- 

 dle of the distal side a conic process truncate at apex and surmounted with a 

 tuft of long hairs; in front of the process are other long hairs, and another tuft 

 at the inner distal corner of this joint. The second joint inserted at the outer 

 corner of the coxa. Other joints somewhat reduced in size, so that the length 

 of the seventh legs does not exceed that of the sixth. The third joint is short- 

 ened more than the others. 



Male genitalia complex, (figs. 216-217) and as we had but one male, dissec- 

 tion was not carried far enough to make plain the relations of the parts. The 

 posterior arm seems to be perforate, the anterior part of it extending up into 

 the complicate anterior arm as two slender columns ( fig. 216 ) . 



Ninth legs of male ( fig. 218 ) with basal joint produced above and angled near 

 the apex with a deep, rounded notch subtended by a sharp tooth; second joint 

 narrower than in Uuderwoodia, hirsute distally and on the lateral face. The 

 pedigerous lamina has long curved ends and is medianly prominent. It may 

 be that this medial prominence is homologous with the long median process of 

 Underwoodia. 



Tenth legs of male (figs. 210-211) with coxfe much enlarged, similar to those 

 of Underwoodia; on the posterior side near the aperture a large rounded promi- 

 nence; also an oblique carina; other joints evidently reduced. 



Eleventh and twelfth legs of male (figs. 212-213) slightly thicker than the 

 normal (fig. 214). Third joint with a few small tubercles on the ventral face; 

 coxse obliquely carinate on the posterior face. 



Color in alcohol, dark brown with a bluish tinge. This may be due to the 

 fact that the specimens are old. lulidse sometimes turn blue in alcohol. The 

 segments have light spots and are coarsely marbled. Legs and antennae dark 

 brown, especially the distal joints. 



Length 15 mm. ; width 1.7 mm. 



Exact localit_y not known, but the specimens, a mature male and 

 female, are evidentl}^ from California. In the same bottle was a
