This genus is very close to Leptogryllus Perkins, differing only in 
the deeper and less prognathous head, decidedly longer palpi, more strongly, 
though very finely, hirsute limbs, closer and more regular minute, but 
stout, spines of the dorsal margins of the caudal tibiae, more elongate 
distal spurs of the same, the dorsal of which, both internally and ex- 
ternally, is more than twice as long as the ventral and very much more 
elongate tarsi. 
In both genera the cephalic tibiae are armed with one, the median 
tibiae with two, very small disto-ventral spines; the cerci are armed 
with a minute spine,” while the female subgenital plate is triangularly 
produced, with apex truncate. 
Stronger in the present specimen than in the examples before us 
of Leptogryllus, in which genus are found occasional individuals that 
lack this spine. 
Length of body 15, length of pronotum 4.3, greatest (meso-caudal) 
width of pronotum 3.8, exposed length of tegmen 1.2, width of tegmen 2.8, 
length of caudal femur 10.8, length of caudal metatarsus 3.1, length of 
ovipositor 8.5 mm. 
LEPTOGRYLLUS Perkins 
1899 Leptogryllus Perkins, Fauna Hawaiiensis, 1, p. 28. 
At the time this genus was proposed, the author described 
seven species, including one previously described by Brunner, and 
in 1910 three more species were described by Perkins. A series 
of forty-three specimens now before us, largely from Oahu and Ha- 
wail, shows that here is a problem sufficiently intricate to necessitate 
extensive collecting, comparison with the types and probably breed- 
ing experiments, before the actual number of valid species of this 
singular Hawatian genus can be determined. 
In the present series at least three groups are found. The 
first of these has the limbs relatively short and heavily annulate. 
To this group belongs forficularis (Brunner), but whether or not 
additional species should be recognized we can not say. The
