1 6 FAUNA HAVVAIIENSIS 



considerable. The ground-frequenting P. pacificum is on the whole the most easily- 

 captured, the arboreal species in spite of their small size will clear several feet in one 

 jump, and several leaps will be made with astonishing rapidity. After this however 

 the distance covered at a leap becomes shorter and shorter till eventually the power of 

 leaping is nearly entirely lost, and the insect attempts to escape by running. 



( I ) Paratrigonidium freycinetiae, sp. nov. 



Frons pallida. Antennarum articulus primus et secundus nigricantes. Pronotum 

 atrum, postice nonnunquam pallidius. Femora antica et intermedia nigricantia. Femora 

 postica supra nigra ; ad apices etiam et externe et interne nigra, ad basini pallida. 

 Tibiae pallidae, anticae et intermediae distincte nigronotatae. Tegmina, cerci, et 

 antennae (basi excepta) pallide flavescentia. $. 



Long, corporis 6 mm., pronoti i'^ mm., tegminum 4'2 mm., femorum post. 

 5 "3 mm., ovipositoris 2 mm. 



Hab. Olaa, Hawaii (2000 ft.). Very rare, three females taken from Freycinetia. 

 I saw one .?, but was unable to capture it. It is excessively wild and active. 



(2) Paratrigonidmm saltaior, sp. nov. 



Frons cum pronoto pallida. Femora antica et intermedia nigra ; femora postica 

 supra nigricantia, externe interneque ex majore parte pallida. Tibiae intermediae anti- 

 caeque, plus minusve distincte, maculatae. Tegmina tota pallide flavescentia. Anten- 

 narum articulus primus sat pallidus. $. (Long. sp. praecedentis.) 



This species is closely allied to the preceding, and only the male sex of the one and 

 the female of the other was taken, but the different colour of the pronotum, and of the 

 hind femora, will readily separate them. The superior tegmen of P. saltator is uni- 

 colorous, pale yellowish, with no dark mark adjoining the vena stridulans, and the front 

 and intermediate femora are entirely of a dark pitchy or black colour. 



Hab. Mountains of Oahu, above 2000 ft. Rare. Apparently attached to the 



Freycinetia. 



(3) Paratj'igonidi^im roseuni, sp. nov. 



Caput cum articulo primo antennarum, et femora omnia laete rosea. Tibiae tarsi- 

 que pallidi. Tibiae posticae roseo-tinctae. Pronotum ex majore parte nigrum. An- 

 tennae, tegmina, et cerci pallide flavescentia. %. 



Long, corporis 7 mm., pronoti I's mm., tegminum 4'5 mm., femorum post. 5 mm., 

 ovipositoris 2*5 mm. (Plate L fig. 9.)
