FAUNA HAWAIIENSIS 



FoRFicuLOiDEA. — Of the genus Aniso/abes, A. annulipes is the most abundant 

 and ubiquitous, being found at all elevations from sea-level to four or five thousand feet 

 in the mountains. ^A. maritima is less abundant, but is very widely distributed and 

 sometimes very common beneath stones in damp localities in the forest region. It also 

 occurs near sea-level. ^A. littot'ea is much rarer than either of the above. We 

 have noticed it on the margin of salt-water ponds on the coast and it has been recorded 

 from a considerable elevation (2000 ft.) in the mountains. The species recorded as 

 "A. pacifica, but which will probably prove to be endemic, has been found only on 

 Kauai, where it lives beneath logs or stones in or near the forest region. It was in 

 company with the young of this species that Japyx sharpi was found, at an elevation 

 of 4000ft. A. annulipes and A. maritima are cosmopolitan species; A. liltorea is a 

 well-known New Zealand insect. 



Labia pygidiata is a very common insect in the forests of all the islands, where it 

 lives beneath bark, especially that of damp and decaying trees. Other species of this 

 genus are of quite recent introduction and found on more than one island. Some of 

 these are known to inhabit Samoa and Fiji, having been found on plants imported from 

 those islands. L. pygidiata is reported from Java and Burma and is, no doubt, of wide 

 distribution. 



A fine Labidura (probably iderica Serv.) is now common on Oahu, under stones 

 in damp places, and beneath trash in the cane-fields. Like many other foreign forms 

 it was probably introduced with growing plants from the Oriental region, where it is 

 widely distributed. It is spreading to other islands of the Hawaiian group. 



Chelisochcs morio is a very common insect, especially in the Freycinetia-^roWmg 

 belt of forest. It generally lives at the bases of the leaves of that plant and of such 

 others as retain moisture, where they clasp the stem. It abounds in such situations on 

 Caiiiia, indica, Cordyline terminalis, and in damp localities on the sugar-cane. Though 

 many lie concealed during the day, others may be noticed running over the leaves of 

 the plants they frequent at all hours. They are largely carnivorous, but also feed on 

 vegetable matter, such as the red inflorescence of the Freycinetia. We have observed 

 them devouring caterpillars and the sugar-cane leaf-hopper. They often seize and hold 

 their prey in their forceps. C. morio is of very wide distribution, ranging from India 

 to the Philippines and through many of the Pacific islands. Most probably it was a 

 natural immigrant or it may have been originally introduced by the natives from other 

 island groups of the Pacific. It was particularly noticed by the naturalists of British 

 expeditions in the early part of last century. We have in recent years found it abund- 

 antly, in company with Sphingolabis kaivaiiensis, in consignments of plants brought 

 irom Fiji, so that it is easily transported by these means. The latter species, 



^ Other species, A. aporonoma, eteronoma, have been described on examples, no doubt similar to those 

 here alluded to as foreign species. 



" Since described as A. perkiiisi (Burr. Tr. Ent. Soc. Lond. 1910, p. 178).
