Analogous to the preceding Insects in the linear for~ of the body, and the length and tenuity of the legs; but the t~o anter10.r ?nes ha:e elongated coxre, and are adapted, as in Manus, for se1zmg their prey( 4). . d We now come to Geocorisre, remarkable for their large e~es, an which have no apparent neck, but whose transversal head IS sepa-rated from the thorax by a strangulation. . They live on the shores of ponds, &c. where they run w1th great swiftness, and frequently make little leaps. Some have a short and arcuated rostrum, and setaceous antenna:. They form the LEPTOPUS, Lat.(5) (1) The thorax in Nabis is not (or but very slightly) divided b! that impr.essed and transverse line which we observe in Reduvius. Here, bes1dcs, the s1mple e es are situated on an eminence or division of the posterior part of the head. ibis latter genus is susceptible of being separated into several subgenera. . (2) Fab., Syst.

IIEMIPTF:RA. 31 In the others the rostrum is long and straight, the labrum projects from its sheath, and the antennre are filiform or a little larger near the extremity. The simple eyes are situated on a tuberde. They are considered by Fabricius as Saldre. Latreil1e separates them into two divisions. His AoANTHI.&-or part of the SALD.&, Fa b.( 1 )-have salient antennre, at least equal in length to half that of the body. Their form is oval. The simple eyes are closely approximated and sessile. In his PELOGONus(2) the antennre are much shortet• and bent under the eyes. The body is shorter and more rounded, and there is a tolerably large scutellum. The simple eyes are remote. These Hemiptera approach the Naucorea, and with the following appear to lead to them. Sometimes the four posterior legs, very slender and extremely long, are inset·ted on the sides of the pectus, and are very remote from each other at base; the tarsial hooks are very smal1, but little distinct, and situated in a fissure of the lateral extremity of the tarsus( 3). These legs are adapted for swimming or walking on water, and are peculiar to the genus HYDROMETRA, Fab.( 4) Which Latreille divides into three subgenera. HYDROMETRA, Lat. Or Hydrometra properly so called, where the antennre are setaceous, and the head is prolonged into a long snout, receiving the rostrum in a groove underneath( 5). GERRis, Lat. Where the antennre are filiform, the sheath of the sucker is triarticulated, and the second pair of legs are very remote from the first, and at least double the length of the body(6). (1) Fab., lb.

(3) The protborax is extended above the m~sothorax, in the form of an elongated plate, narrowed and terminated in a point, representing the scutellum under which the elytra originate. The mesothorax is greatly elongated. ' (4) Fab., Syst. Ryngot. ' (5) Lat., Gener. Crust. et Insect., HI, p. 131. (6) Lat. lb. |
