I also searched the Little Barrier Island for tuataras, but in vain. The large quantities of feral pigs living upon that island may easily account for their absence. There are also none on the Hen and the Guano Islands. Most frequently they were found by me on the large western Chicken Island. I believe that they are still more abundant on the smaller islands; however; although I tried repeatedly to land on them, the heavy surf would not allow me to do so.

Art. XL.—On some new and undescribed Species of New Zealand Insects, of the Orders Orthoptera and Coleoptera. By W. Colenso, F.L.S. [Read before the Hawke's Bay, Philosophical Institute, 8th November, 1880.] Orthopter Fam. Mantide Genus Mantis Mantis novs-zealandie n. sp Pronotum five lines long, anterior end widest, ridged down the middle minutely tuberculated all over in scattered dots, punctulate, punctures translucent when viewed between eye and light, side-margins rough finely sub-serrulate, edge straight sloping gradually to mesonotum Anterior pair of legs: trochanter very slightly serrulate at margins; femur two rows of spines of irregular lengths, inner row small and closely set, outer four only large and distant, a large purple oval or kidney-shaped spot central within; tibia two rows of spines, regular, ending in one very long curved one at base; tarsus long; costce of the anterior wings (elytra), one to each, run longitudinally parallel with and near the outer margin, with transverse flexuose nerves branching inwardly and diagonally, from it, wholly filled up between them with fine anastomosing veinlets; elytra semi-transparent; posterior wings much smaller and very membraneous; wings extending far beyond base of abdomen; abdomen thick smooth Antennce short, 3½ lines long;eyes large, two small portuberances (? stemmata) between horns and just behind them: total length from head to posterior edge of elytra 1½ inches: length of nympha 1½ inches. Colour (of both states nearly alike) mostly light emerald green; underneath, about mouth and thorax, and inside of fore-legs pale lemon; outside of legs and head (above) dark orange; a dark purple reniform spot on inside of each fore femur. Hab.—Scinde Island, Napier, on trees (nympha state only), 1878–1879, Mr. J. A. Rearden; imago state (one specimen), 1880, Mr. J. D. Ormond. This species has pretty close affinity with the European species M. religiosa, but it is very much smaller, with shorter horns, and less spiny and narrower fore-legs, etc.
