ORTHOPTERA 



19 



This species greatly resembles P. viricicscens, in dried examples, although when 

 fresh, and not discoloured, it has a totally different appearance. It appears to be a 

 variable species, and the examples taken in different localities are rarely altogether 

 similar. 



Hab. Puna (2000 ft), and Kau (4000 ft.), Hawaii ; mountains of West Maui ; 

 Honolulu (2000 ft.); Makaweli, Kauai (2000 ft.). Apparently always rare. It is an 

 arboreal species. 



(9) Paratrigonidiuni grande, sp. nov. 



Statura majore, colore testaceo vel brunneo. Frons cum pronoto plus minusve 

 atro- vel fusco-notata. Antennae articulis multis nigricantibus variegatae. Tibiae 

 anticae et intermediae distincte fusco- vel nigro-maculatae. Femora postica interna 

 notis compluribus nigris ornata. Tibiae posticae supra ex majore parte fuscae vel 

 subnigrae, ad basim spinarum pallidae. $ Tegmen dextrum post venam stridulantem 

 plaga triangulari nigra, laevi, haud rugosa. $ $. 



Long, corporis (cum tegminibus) $ 9*5, $ 87 mm.; pronoti $ 17, $ 2 mm.; 

 tegminum ^ 7, ? 575 mm. — Lat. tegminum $ 3'8 mm. — Long, femorum post. $ 6'2, 

 $ 6'2 mm.; ovipositoris 3 mm. (Plate I. fig. 12.) 



Hab. Hawaii, in the Puna, Kau, and Kona districts. Lives beneath the bark 

 of trees, coming outside only at night. The young are of the same colour as the 

 adult, not green like those of the three preceding species. The large size, combined 

 with the smooth area behind the vena stridulans of the $, will distinguish this species 

 from any other. 



(10) P aratrigonidium crepitans, sp. nov. 



Testaceum, capite plus minusve fusco-variegato, antennarum articulis basalibus 

 pallidis. Pronotum fusco-variegatum. Femora omnia distincte nigro-notata ; tibiae 

 posticae variegatae. Cerci pallidi, breviores. Tegmen ^ dextrum post venam stridu- 

 lantem macula nigra ornatum, hac plaga tota rugulosa. i%. 



Long, corporis (cum tegminibus) J" 7, ? 6 mm. ; pronoti % i "5 mm. ; tegminum 

 t 5'5> ? \'- mm-; femorum post. ^ 5'2, % 5'5 mm.; cerci ^ 3'25 mm.; ovipositoris 

 2'5 mm. 



Very like P. filicimi and the allied species in general appearance, but the $ is 

 quite distinct by the evidently less smooth (more rugulose) dark area behind the 

 vena stridulans. 



Hab. Kauai (4000 ft.), rare, or at least very difficult to obtain, living amongst 

 heaps of dead wood, or in low vegetation.
