    truncate, which has similar habits, living m barrows in the sand along the edges of lagoons and creeks. It measures an inch in length, and is of a general reddish brown tint mott ed with dull vellow; and the dorsal segments of the abdomen are deeply barred with reddish black almost confluent down the centre. The head is large; the protliorax small, with t e elytra and wings well developed; the abdomen, rather narrow at the base, is broadest behind the large callipers, which are slender, furnished with two blunt teeth on the inner edge and meet at the extremities. It differs from L. npara in having the apical edge of the last abdominal segment trun- cate, and not scalloped as in the formei. 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 colossal, our largest common wingless species, also recorded from New Caledonia, was described by Dohrn (Ann. Museo Genov. 1ST9), and a second variety by Burr under the name of A. minor in 1902; but it is most mi vi- able in size, ranging from o\er 1,2 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 ter- minating in a pair of short stout hnger- like appendages fitting close togeth and turned up slightly at the tips. A second species of Anisolabis com- mon in Tasmania and recorded from Gie top of Mount Wellington is black some what broad and flattened on the dorsal surface, with the anal appendages slioit, suiiaiL, \ ]eft Side as if they slender, and twistec ^ degcribed by Bormans (C.R.
