 Hind femora slender, shorter than tibiae, slightly less than twice as long as 

 fore femora, outer face with a few scattered small nodules, both lower 

 carina? armed with a few small distant slender teeth. Ovipositor short, 

 less than two-thirds the length of hind femora, its apical third slender, up- 

 curved, apex acute; inner valves armed with six or seven very short and 

 broad apically rounded teeth, the basal one one-halt' more distant from the 

 second than the intervals between the others; terminal hook very small, 

 feebly decurved. Length of body, 9, 19.5 22; of pronotum, 5.2; of fore 

 femora, 10; of hind femora, 18.7 20; of hind tibiae, 20; of ovipositor. 

 7 8 mm. 



Known definitely only from the Nickajack Cave, Term., one of 

 the two female types being- an alcoholic specimen in the Cambridge 

 Museum. 'Very distinct from all other species in the armature of 

 the ovipositor, which is crenulate, not serrate in character. Aside 

 from the type locality this species has been recorded only from 

 Sugar Grove and Columbus, Ohio (Kostir), but this record is due 

 to an error in identification, an examination of the specimens 

 showing them to be C. tenebrarum Scudd.
