OR THOP TERA 689 



(2) Leptogryllus apicalis, sp. nov. 



Colour, size and form generally as in L. nigrolineatus, the tegmina in the male 

 covering nearly all the metanotum. the posterior femora dark or black for a large extent 

 on the basal portion. Length ^ 18 mm., hind femora 12 mm. 



Hab. Molokai and Maui (3000 ft). 



(3) Leptogryllus deceptor, sp. nov. 



Extremely like L. nigroliHeaius having the same colouration but distinguished at 

 once by the small laterally placed tegmina, leaving the metanotum mostly exposed, and 

 the ovipositor is apparently longer. Female. Length of hind femora 12 mm.; 

 ovipositor 9 — 10 mm. 



Hab. Oahu, 1500 — 2000 ft. 



Prognathogryllus Brunn. 



The genus Nesogryllus is the male of Prognathogrylltis and was originally separated 

 largely on account of the quite different cerci. It is noteworthy that in the allied genera 

 there is no such sexual difference in these organs. The species are difficult and 

 specimens from the other islands are so close to the Kauai and Oahu forms, as to be 

 inseparable without a good series of specimens, especially as those taken in numbers 

 appear to show considerable variation. 



MANTOIDEA. 



A second species of this group has been imported to the island of Hawaii, where it 

 is now common in some localities and spreading. 



Paratenodera Rehn. 

 (i) Paratenodera sinensis Sauss. 

 Hab. Hawaii ; now common on the windward side-; first taken in 1900.
