differing from tlie otliers in external appearance. The form of 

 the genitalia and ninth male legs is so distinct and characteristic 

 as to make identification easy. 



Cleidogona fustis sp. n. 



Plate VIII, figures 151-153. 



First legs of male six-jointed, the joints, beginning with the coxa, .20, .06, 

 .30, .12, .10 and .38 mm. long; third and fourth joints .10 mm. Two superior 

 secondary claws and a small inferior one. 



Second legs of male also six-jointed, the joints .20, .06, .32, .14, .10 and. 32 

 mm. in length; width of third joint .12 mm. 



Third legs of male seven-jointed, .22, .04, .32, .36, .14, .10 and .40 mm. in 

 length; width of third joint .20 mm., somewhat enlarged toward the distal 

 end. Seventh joint with hook-like transparent roughenings like those of 

 Conotyla fischeri, but smaller. The third joint with a few conic or knob-like 

 protuberances on the inferior surface. 



Fourth legs of male seven-jointed, the joints, beginning with the coxa, .24, 

 .04, .40, .44, .14, .12 and .44 mm. long. Seventh joint roughened as on third 

 legs. The third joint with a few knobs, as on the fifth leg. 



Fifth legs of male with joints .24, .04, .48, .46, .18, .10 and .44 mm. in 

 length. Inferior surface of third joint covered with small knobs about .04 

 mm. in diameter. Seventh joint with inferior secondary claw, apex with pro- 

 cess like the twelfth legs. 



Sixthlegsof male with joints .28, .04, .44, .46, .18, .12, .44 mm. Third 

 joint si^arsely covered with cones and knobs. Seventh joint as given for 

 seventh legs. 



Seventh legs of male with joints .28, 04, 42, .48, .16, .10, 42 mm. long, .26 

 mm. wide; coxa with a large transparent rounded protuberance, about as long 

 as wide (.06 mm), covered, like the surface of the coxa, with sparse small 

 knobs, smaller than those of the third joint. Third and seventh joints as for 

 the sixth leg. Distal two-thirds of inferior svirface of seventh joint roughened 

 with crowded, appressed, distally directed short, sharp, bayonet-like processes. 

 One superior and one inferior secondary claw. 



Tenth legs of male with joints respectively .36, .04, .38, .46, .16, .10, and 

 .48 mm. long, width of third joint .20 mm. First joint thickened distad, and 

 with two large protuberances, one conical, the other larger; and of irregular 

 shape. The first is chitinous, the second membranous, apparently protruded 

 from an aperture. Inferior surface of third joint thickly covered with very 

 flat knobs. Seventh joint with distal half as on seventh legs. The superior 

 apical angle of this joint seems to be produced into a curved, claw-like, chit- 

 inized process nearly equalling the true claw in size. A small inferior 

 secondary claw. 



Eleventh legs of male with joints respectively .36, .04, .32, .46, .14, .12 and 

 .50 mm. long; third joint .18 mm. wide. Coxa with a large irregular process 

 at about the middle of the inferior surface, directed meso-caudad. Seventh
