Tlie present insect is in all probability a southern race of N. palus- 

 tris, distinguished only from that species by its peculiar and striking 

 coloration. Unsuccessful efforts have been made to obtain additional 

 material from the region in which the type series was taken, and 

 until this can be done it is, in our opinion, advisable to consider the 

 present insect a geographic race, although it may eventually prove 

 to be a mere color variety. 



Type: d^; Thomasville, Georgia. In sphagnum. December 6, 

 1903. (Hebard.) [Hebard Collection.] 



Description of Type. — The head, pronotum, and ventral surface of 

 the insect is ochraceous-rufous, the limbs almost uniform ochraceous, 

 and the tegmina and dorsal portion of the abdomen shining black. 

 The maxillary palpi are pale yellowish, with the exception of the last 

 segment, which is darker at the base, shading to clove brown in the 

 apical half. 



The female allotype, here selected, bears the same data as the 

 type and is in the same collection; it is slightly larger than the type, 

 but of the same coloration.
