the tegminal width, whereas the rest of the series have minute,

Leptogryllus, sp. 
A male and an immature male from Mount Olympus, Oahu, 
taken September 5, 1915, by A. Busck, in the United States Na- 
tional Museum, are of the same general body bulk as the series of 
L. nigrolineatus Perkins, have the limbs immaculate and minute 
lateral tegmina, but the caudal femora short and stout. 
These specimens can not be placed at the present time with 
any certainty. They have a distinctive facies, are too large for 
forficularis and much too short limbed for nigrolineatus. 
The measurements of the adult male are: length of body 16, length 
of pronotum 4, width of pronotum 3.6, exposed length of tegmen 0.4, 
width of tegmen 0.9, length of caudal femur 9.3, width of caudal femur 
2.6 mm.
