(2) Prognathogryllus elotigattis, sp. no\'. 



Gracilis, elongatus, colore testaceo. Tegrnina pallida, fere ad apicem segmenti 

 abdominis secundi se extendentia, venis flavis. Femora postica gracillima, spinis internis 

 externis evidenter longioribus. $. 



Long, corporis 22 mm., pronoti 4, tegminum 5-5, femorum post. 11, ovipositoris 

 7 mm. (Plate I. fig. 15.) 



A very distinct species, which, although of nearly the same length as the preceding, 

 appears much longer, owing to its much narrower form. The posterior femora are very 

 slender and much less wide at the base, and the inner series of spines on the posterior 

 tibiae are much less strong. 



Hab. The high plateau of Kauai. July, 1896. 



(3) Prognathogryllus robustus, sp. nov. 



Brunneo-niger, robustus. Tegmina fere ad apicem abdominis se extendentia. 

 Tibiae posticae cum femoribus minus elongatae, spinis internis quam externis multo 

 longioribus. %. 



Long, corporis 16 mm., pronoti 4, tegminum 9, femorum post. 9, ovipositoris 

 10 mm. (Plate L fig. 14.) 



Quite unlike the other species in general appearance, of a dark brownish colour, 

 and with well developed tegmina. The wings are much shorter than these. The 

 posterior femora are formed much like those of P. alatus. The inner series of spines 

 on the posterior tibiae is much more strongly developed than the outer, but they are 

 shorter than those of P. alatus. 



Hab. High central plateau of the Kauai mountains. Very rare, a single % only 

 taken, high up in a dead tree amongst the dry leaves that still adhered. 



(4) Prognathogryllus oahuensis, sp. nov. 



Haud robustus, flavo-testaceus, pronoto fusco-variegato. P. elongato simillimus, 

 femoribus tibiisque posticis multo brevioribus facile distinguendus. %. 



Long, corporis 16 mm., pronoti 4 mm., tegminum 5 mm., femorum post. 9 mm., 

 ovipositoris 6 mm. 



Easily known from P. elongattis, which (of the preceding species) it most resembles, 

 by the shape of the posterior femora, which are much wider near the base in proportion 

 to their length.
