 the point from which it originated was located within a few 

 inches, though great care had to be exercised not to disturb 

 the singer. It proved to be a male of this species, in a cham-

 merely a slight enlargement of its gallery. Others were traced 

 down in the same way, and as a result of a number of attempts

 heard chirping in a similar area on the other side of the

 New Buffalo, September 2, 1919, i female. 



This species was found in small numbers in company with 

 the much more numerous ElUpcs minuta, on moist sand and 

 mud shores along the Galien I^iver, on the sandy margins of 

 spring pools on a marshy hillside near the Warren Woods 

 Preserve, and on small exposed areas of moist sand amoiig

EUipes uiinuta (Scudder). 



Warren Woods, June 2j to September 3, 1919, 9 males, 12 females, 

 14 immature specimens. 



These minute mole-crickets were found in moderate num- 

 bers in the same situations as Tridactylus apicalis. Along the 

 Galien River they were fairly numerous on the moist sand and 

 mud shores, but more common on the areas of bare, trampled 

 mud about the watering places of the cattle. In the vicinity
