Tills species, wliicli also belongs to the subgenus Eunemobius, is 

 one of the most distinctive of the North American species of the genus 

 Ne7nohiiis. In the original description the supposed male of the 

 present species was in fact N. maculatus, and in consequence that 

 composite description is highly misleading. There is a superficial 

 resemblance of this species to N. palustris, but examination shows 

 that it belongs to a different subgenus, since in cojifusus the disto- 

 ventral spurs of the caudal tibiae are equal in length and the ovi- 

 positor is of the shorter type, armed at the apex above with heavy 

 teeth, below with widely spaced serrations. 



The bone-white maxillary palpi in both sexes distinguish the present 

 species from all other North American members of the genus. 

 The nearest relationship is found in A^. caroUnus, from which species 

 confusus differs widely in the different color pattern, much darker 

 general coloration and ovipositor which is different in shape and 

 armament. 



Based on a series of specimens from two localities in Indiana. 



Single type here designated: 9 ; Tippecanoe Lake, Kosciusko 

 County, Indiana, August 26, 1902. (Blatchley) [Blatchley Col- 

 lection]. 



Description of Type. — Size small, form graceful; head small, not 

 as full and with interantennal projection not as prominent as in 

 carolinus, wider than the cephalic width of the pronotum. Maxillary 

 palpi sunilar to those of carolinus. Eyes broad ovate, not at all 

 prominent. Pronotum with proportions much as in carolinus, 

 narrowing slightly cephalad and with a medio-longitudinal impressed 

 line more noticeable in the cephalic portion. Tegmina half as long
