The next large Genus _Anisolabis_ is also world wide in its range and contains 36 described species, 3 of which are recorded from Australia, 2 from Tasmania, 1 from New Zealand, and 1 from Norfolk Island. _Anisolabis colossea_, our largest common wingless species, also recorded from New Caledonia, was described by Dohrn (Ann. Museo Genov. 1879), and a second variety by Burr under the name of _A. minor_ in 1902; but it is most variable in size, ranging from over 1½ inches in length to less than half an inch. It is of a uniform dull reddish brown colour, with a rounded head, truncate thorax, and elongate broad abdomen terminating in a pair of short stout finger-like appendages fitting close together and turned up slightly at the tips. A second species of _Anisolabis_ common in Tasmania and recorded from the top of Mount Wellington is black, somewhat broad and flattened on the dorsal surface, with the anal appendages short, slender, and twisted over to the left side as if they had been damaged. It was described by Bormans (C.R. Soc. Ent. Belg. 1880) under the name of _Anisolabis tasmanica_. [Illustration: =Fig. 4.=--_Anisolabis colossea_ (Dohrn). The large wingless earwig. (Original W. W. Froggatt.)] _Labia grandis_ described by Dubrony (Ann. Museo Genov. 1879) comes from North Australia. The genus contains 47 described species; several undetermined species in my collection are small dark brown earwigs with well developed elytra, and anal appendages very narrow at the base, small, and curving over at the sharp tips.

J. Walker taken in New Zealand, who told me he had also captured it in Tasmania, so that it is more than probable it will be found on the mainland. Family 2. Cockroaches. BLATTIDAE.
