Illustrated Life-histories of New Zealand Insects: No. 2. By G. V. Hudson, F.E.S., F.N.Z.Inst. [Read before the Wellington Philosophical Society, 30th September, 1921; received by Editor, 13th October, 1921; issued separately 8th July, 1924.] Plate 32. I Did not originally intend to include the Coleoptera within the scope of these notes, but, having had the good fortune to breed four species during the past season, I am tempted to publish the results, more especially as these beetles all belong to families of whose preparatory stages little is known. On this occasion I also include an account of the life-history and habits of a member of the order Hemiptera (suborder Homoptera). Order Coleoptera. Family Trogositidae. Leperina sobrina. (Plate 32, fig. 8.) Leperina sobrina White, Manual N.Z. Coleoptera, 1, 178. This interesting beetle is fairly common in the neighbourhood of Wellington. Its larva is found in burrows in the solid timber of various trees, the specimen actually reared having been discovered in the stem of a dead nikau-palm (Rhopalostylus sapida). The length of the full-grown larva is about ⅝ in. It is very stout, with a horny blackish-brown head; a semicircular horny plate on the back of the second segment and two smaller plates on the dorsum of each of the third and fourth segments. The hind-body is very soft and fat, ochreous-grey; the terminal segment is black and very horny, armed above with two strong projecting processes. (See Plate 32, fig. 9.) The pupa state is spent in the burrow inhabited by the larva, and the perfect beetle remains hidden in this retreat for many days after its emergence whilst its integument gradually hardens and acquires its natural colours. Family Cucujidae. Cryptamorpha brevicornis. (Plate 32, fig. 5.) Cryptamorpha brevicornis White, Manual N.Z. Coleoptera, 1. 221. This very active, beetle is often abundant under the loose bark of felled hinau-trees (Eleocarpus dentatus), especially when saturated with moisture. The larva (Plate 32, fig. 6), which is even more active, is found in similar situations. Its length when full-grown is about ½in. The antennae are about three times the length of the head, the body elongate narrow and much flattened, dull greenish-brown with a pair of pale spots on segments 5–11 inclusive and a darker dorsal streak throughout. The armature on the terminal segment consists of a long forked process, rising almost vertically from the dorsum, and when seen from above very much foreshortened. This larva is almost certainly carnivorous. The pupa (Plate 32, fig. 7) is secreted in a crevice on the inner side of the bark, its terminal segments remaining enclosed in the old larva] skin. The beetles emerged in December.
