Mr. R. Templeton's Descriptions of the Irish Species of Thysanura.

PLATE XI FORBICINA, Geoff. Sp. 1. Polypoda, Linn. Plate XI. Fig. 1. Very common in dry stone ditches and mossy places. Fig 1. Outline of the animal magnified. la. Head seen in front. 1b. Superiorly. 1 c. Antenna. 1d. Last joint of the palpus. 1 e. The foreleg. 1f. The hind foot. 1g. Jaws, which are very thin and membranous. 1 h. Inside, showing the auxiliary legs; the back is placed to the right. 1 l The auxiliary foot, with which it ascertains the presence of the object against which the tail is adpressed. 1k. A scale, much magnified, to show the lines producing the iridescence, from 9,000 to 11,000 in an inch.

ORCHESELLA Sp. 1. Orchesella filicornis. Plate XI. Fig. 2. Fig. 2. Insect magnified. 2 a. Left antenna.

Sp. 2. Orchesella cincta (vaga, Fab.?). Plate XI. Fig. 3. Fig. 3. Insect magnified.

PODURA, Linn. Sp. 1. Podura plumbea, Linn. Plate XL Fig. 4.

Fig. 4. The insect magnified. 4 a. Left antenna. 4 b. Configuration of the left eyes. 4c. Represents the mouth; x, the positions of the antennae; +, a cylindric ring, moveable, and inclosing the manducatory organs ; °, the labium, transverse, striated longitudinally in the middle, and with a minute hemispheric tubercle laterally, closely adpressed against ° in the state of rest. 4°. The labrum fimbriated at its apex along the diameters of two convex semicircles placed on the basal part of the lip . There is no appearance of lateral pieces internally, or anything resembling maxillae. These lips are moved to and fro with considerable rapidity, but seem to have little prehensile power, as they were unable to seize upon the minute hairs of the sable pencil which I passed into the mouth. A singular apparatus is protruded from the 1st abdominal ring beneath, which will be noticed under Podura stagnorum : it is common to all the Podurae.

Sp. 2. Podura nitida. Plate XI. Fig. 5. Fig. 5. Insect magnified. 5 a. Antenna of left side.

Sp. 3. Podura nigro-maculata (minuta, Fab.?) Plate XI. Fig. 6.

Fig. 6. Insect magnified. 6a. Antenna of left side, seen in profile.
