We now pass to G eocon.s re .m which the antennre, a. lso filidfo rm or thicker at the extremi•t y anc1 qua d n·a r t' culated are mserte 1o wer l ' than the preceding ones, e.l ther on an ·l magm· a ry line ' drawn1 1f' rom the eyes to the orl. gt.n of the 1a b rum, or beneath it . The oce 1f ahre approximated to the eyes, and the membranous appendages o t e elytra frequently present but four or five nervures. f Here the head is not narrowed posteriorly in the manner o a neck.

It is sometimes, though very rarely, found WI ihgs. Those species, in wh t the anterior thighs are inflated, form the genus PAoHYMERA of MM. Lepeletier and Serville, a natne already employed, and which must be changed( 1 ). SALDA, Fab. Where the head taken in its greatest breadth, is as wide as the thorax or wider, ~nd has its posterior angles dilated, with large eyes, and where the thorax is always of equal wi~th a~d square(2). There, the head is ovoid and narrowed postenorly 10 the manner of a neck. MYonooHA, Lat.(3) We have now arrived at Longilabra, in which the antennre, composed of four joints, become gradually thinner towards the ex· tremity, and frequently even abruptly so, or are setaceous. · In our Faro. Nat. du Reg. Anim., we have for~ed the subgenus (1) See Fab., and Lat., Gener. Crust. et Insect., III, p. 121: (2} The Saldre, atra, albipennis, grylloides, Fab. · (3) Sec Lat., Gener., &c., and Encyc. Methodique. IIEMIPTEHA. 27 ASTEMMA, With certain species in which the antennre are gradually setaceous and where the second joint is of equal thickness and almost glabrous. The thorax is hardly narrower before than behind, and forms a transversal square, or is cylindrical; the head is as if incised perpendicularly or rounded at its origin( 1 ). MIRis, Fab. Similar to Astemma in the antennre, but removed from it by the thorax, which is much wider posteriorly than before, and trapezoidal( 2). CAPsus, Fab. A similar and trapezoidal thorax, but the second joint of the antennre is attenuated at base, and densely pilose, particularly towards the extremity, otherwise almost cylindrical ~nd slender like the first(3). HETEROTOMA, Lat. The Heterotomre are very distinct from,.the preceding Insects by the size and width of the two first joints of the antennre, and of the second particularly, which forms an elongated palette; the two last are very short( 4 ). In the remaining Hemiptera of this family there are but two or three apparent joints( 5) in the sheath of the sucker; the labrum is short and without strire. 'rhe first joint of the tarsi, and frequently even the second, is very short in the greater number. Sometimes the legs are inserted in the middle of the pectus; they terminate by two distinct hooks which originate from the middle of the extremity of the tarsus; they can neither be used as oars, nor for running on the water. We then sepante those species in which the rostrum is always (1) The Snldz pallicornis, jlavipea, Fab., and some other species, but in which the body is much narrower and longer, and somewhat more analogous in the head to the Myodochz.
