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.
