Part 22

Corixa zealandica, n.s. (Plate XX., fig. 5).

Abundant throughout the summer in all slow-running streams. The larva closely resembles the imago except that it has no wings. Its food probably consists of the juices of other insects. The present insect invariably swims with {121}its back exposed, thus differing considerably from the English Water-boatman (Notonecta glauca), whose keel-like back is kept beneath the water, while the two long hind-legs are rapidly moved backwards and forwards like oars.

Family SCUTELLERIDÆ.

Cermatulus nasalis (Plate XX., fig. 6, 6a larva).

This insect may be beaten out of various trees during the summer, and is usually taken in some abundance in February amongst white rata blossoms, on which it may be often observed sucking the honey from the blossoms with its long rostrum. Its larva, which is represented at Fig. 6a, is found in similar situations.

This concludes the series of insects I have selected as representative of the several orders in New Zealand. The brief sketch of entomology thus given is of necessity extremely fragmentary, and many important groups and families are entirely unrepresented. Should, however, this little book induce some of its readers to investigate insects for themselves, I shall feel that my efforts have been amply rewarded.
