SYSTEMATIC ARRANGEMENT

Perhaps the largest of the European Ichneumonidæ, and met with occasionally in most parts of Britain.


STEPHANUS CORONATUS.

Plate XXXII. Fig. 2.

Jurine's Hymenop. Pl. 4, genus 4.

In this group the head approaches to a globular form, the mandibles terminate in an entire or slightly notched point; the thorax is narrowed and elongated in front, and the abdomen appears almost sessile. The antennæ are long and slender, consisting of 32 joints. The species named coronatus is black, the abdomen dark red; legs likewise red, the tarsi and and anterior tibiæ pale. The insect is usually found, according to Jurine, on dry wood, and, when it flies, the abdomen forms a right angle with the thorax.


PELICINUS POLITURATOR.

Plate XXXII. Fig. 3.

Drury's Exotic Ins. Vol. II. Pl. 40, fig. 4.

This generic group is at once known by the singular appearance of the abdomen, which is very long, nearly filiform, arched, and inserted in the thorax a little above the origin of the posterior legs. The hinder legs are thickened, and the antennæ straight and extremely slender. The species above referred to is entirely black, the wings tinged with brownish yellow. It is a native of Jamaica. It is probable that the very long and slender abdomen serves, in these insects, the same purpose which a lengthened ovipositor does in others, enabling them to place
