Descriptions of two Hymenopterous Insects. 57 VI. Descriptions of two Hymenopterous Insects from North-ern India. By W. W. Saunders, Esq., F.L.S. &c. [Read 7 January, 1839.] The two insects which J am at present about to describe were collected in the northern provinces of India by Lieut. J. Camp-bell of the Bengal Artillery, and form part of a small collection sent by him a short time since to this country. The first is a very interesting insect allied to Myrmica, but from which it ap-pears to differ in the neuration of the wings, the two-jointed pedicel to the abdomen, and in the articulations of the antennse, and I therefore propose forming a new sub-genus for it which I shall term " Myrinicaria," and thus characterize. Myrmicaria, Head transverse, with the ocelli placed in a triangle on the vertex. Eyes lateral, small, oval and prominent. Antenncc fili-form, inserted in the front of the head in a line drawn between the eyes, rather longer than the thorax, distinctly thirteen-jointed ; the first joint as long as the second and third ; the second very small ; the fourth to the thirteenth smaller than the third, and gradually decreasing in length to the terminal joint, which is nearly as long as the third. Mandibles small, almost concealed. Thorax ovate, very convex, prominent in front. Scutellum semi-ovate, prominent, forming, with the metathorax, an abruptly in-clined plane. The superior wings with the stigma strongly marked, one cubital and one discoidal cell complete, and three cells on the apical margin sub-complete ; the radial, discoidal, and sub-discoidal nervures nearly reaching the apical margin. Legs long and slender, with the posterior tarsi elongate. Abdomen subcordate, petiolate ; the two first joints inversely clavate and forming the petiole ; the terminal or seventh joint minute, and provided with two projecting valves. M. Brunnea. (Plate V. fig. 2.) Shining chesnut brown, hairy ; eyes black ; posterior margins of the five terminal segments of the abdomen dark brown ; wings lightly tinged with brown, the nervures and stigma the same co-lour as the body ; femora and tibiae somewhat darker. Length -^^ inch, width -f^ inch.
