ORTHOPTERA 



17 



Hab. Mountains of West Maui (3000 ft.). A single ? taken from Metrosideros. 

 Like the preceding it is a very quick and strong jumper and difficult to seize. I saw- 

 several other specimens, when the individual described above was taken, but was un- 

 able to revisit the locality. 



(4) Pai'atrigonidium atroferrugineuni Brunn. 



Paratrigonidium atroferrugineuni Brunner P. Z. S. 1895, P- 895. 



(Plate I. fig. 10.) 



This is a very distinct species, and cannot be confused with any other. The black 

 tegmen of the Z with its orange-coloured border, and the black femora with red apices 

 in both sexes, give it a very distinctive appearance. The tegmina of the % are generally 

 entirely pale, but sometimes black in the centre with a ferruginous border, very much 

 as in the ^. 



Hab. Island of Molokai only. Lives in the leaves of Metrosideros polymorpJia, 

 but chiefly if not solely in those of one special form of this very variable tree. The 

 young of the cricket is entirely green in all its stages. 



(5) Paratrigonidium subroseum, sp. nov. 



Totum pallidum, plus minusve roseo-tinctum, femoribus tibiisque omnibus imma- 

 culatis. Z %. 



Long, corporis t 7'5. ? r'5 mm. ; pronoti t i'5, ? i'5 ; tegminum t 5'6, ? 4"8 mm.; 

 femorum post. ? 5, ? 5'2 mm. ; ovipositoris 2-5 mm. 



This is a very distinct species. There is no dark spot on the tegmen behind the 

 vena stridulans, such as is present in most of the Hawaiian species. In the immature 

 stages the insect is entirely green. After death the rosy pigment has a tendency to 

 become massed in certain parts, as is also the case with the green pigment in other 

 species, but the legs are in reality quite unspotted. 



Hab. Mountains of Oahu (2000 ft.). Attached to bushy trees o{ Metrosideros. 



(6) Paratrigonidium Jilicum, sp. nov. 



Brunneum, testaceum, vel olivaceum. Frons pallida, nonnunquam notis fuscis, 

 plerumque minus distinctis, ornata. Antennae subinfuscatae, basim versus articulis 

 paucis, rare dispositis, obscurioribus. Tibiae anticae minus distincte fusco-notatae. 

 Femora postica interna fere concoloria, vel tantum duabus notis minus distinctis fuscis 

 signata. Tibiae posticae supra pallidae. t Tegmen de.xtrum post venam stridulantem 

 plaga triangulari nigra ornatum : hac, majore ex parte, laevi, minus rugosa. Cerci 

 minus elongati. (Plate II. fig. 6.) <? $.
