This genus is very close to Lrptoi^ryllus 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

At the time this gentis was proposed, the author described 

 seven species, including one previously described by Brunner, and 

 in T910 three more species were described by Perkins. A series 

 of forty-tlu^ee specimens now before us, largely from Oahu and Ha- 

 waii, 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 Hawaiian 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 forficiilaris (llrunner), but whether or not 

 additional species should be recognized we can not say. The
