Figures 6-8. — Habit sketches of three species of the Mesochorea section, lateral aspect. 

 6, Camharincola mesochorea, new species, paratype, Perry Co., Indiana (a little smaller 

 than the normal adult size). 7, C. restarts, new species, paratype from Benton Co., 

 Arkansas. 8, C. ouachita, new species, holotype, Chautauqua Co., Kansas (specimen 

 distorted in preservation). All figures drawn to same scale. 



Male reproductive system occupying most of one side of the coelom 

 of segment vi. Bursa elongate-fusiform, much longer than broad. 

 Ejaculatory duct in type specimen recurved first ventrad then 

 abruptly dorsad, drawing down the caudal end of the spermiducal gland. 

 Latter elongate, cylindrical, curving cephalad across top of bursa, 

 then ventrad to level of the middle of latter, thence mesad and taper- 

 ing into the anterior deferent duct. Posterior deferent lobe very 

 large and conspicuous, located at about midlength of spermiducal 

 gland, directed caudad over base of ejaculatory duct and apex of 

 penial sheath, thence caudomesad to merge with the posterior deferent 

 duct. Prostate as large in diameter as spermiducal gland, curving 

 along its dorsal side as far as the beginning of the anterior deferent 

 lobe. 



Spermatheca not completely visible in either type specimen, but 

 appearing to be composed of a slender ectal duct and a subglobose 

 ental bulb, no ental process observed.
