This paper contains an account of various Lithobiomorpha collected from 

 time to time in different parts of New Zealand. Hitherto only six species 

 of the suborder have been known from this country — Lithobius argits 

 Newport, Henicops maculatus Newport. H. impressus Hutton, Lamyctes 

 emarginatus (Newport), Haaseilla insularis (Haase), and Anopsobius neo- 

 zelanicus Silvestri. In the following pages three new species of Lamyctes 

 are added, including one from the Kermadec Islands and another from 

 the Chatham Islands : the genus Paralamyctes, hitherto. unknown in New 

 Zealand, is represented by two new species ; and a new genus, Wailamyctes, 

 with two new species, is described from specimens collected in Canterbury 

 and Stewart Island. 



Key to the Families. 



1. Sternite of prehensorial segment absent, labrum tridentate, no tibial 



spurs . . . . . . . . . . . . . . Lithobiidae. 



2. Sternite of prehensorial segment well marked, labium unidentate, 



tibial spurs present on most of the legs. 



a. Spiracles on first pedigerous segment . . . . . . Henieopidae. 



a 1 . No spiracles on the first pedigerous segment, coxal pores 



on the last two segments . . . . . . Anopsobiidae. 



The family Zygethobiidae (Chamberlain), which is not represented in 

 New Zealand, stands near the Anopsobiidae, from which it differs in having 

 coxal pores on the last four segments.
