( 51 ) VII. Monograph of British Braconidse. Part II. By the Rev. T. A. Marshall, M.A., F.L.S., &c. [Read February 2nd, 1887.] Plate V. IV. POLYMORPHI. Of the ten subfamilies brought together under this heading, the two first only have a natural affinity. The others, as explained at the beginning of Part I., are isolated and heterogeneous, being, in fact, each of them the type of a higher division. To effect their rational arrangement it would be necessary to take into account all the exotic forms, when it would probably be found that many or most of the subfamilies and their genera, constituted for the reception of European species, would have to be modified or exploded. With regard to the first two subfamilies, they might be classed together as one group Petiolarii, equivalent to the Areolarii, &c, established by Wesmael ; but it would avail nothing to commence a system of division which could be carried no further. XIV. EUPHORIDES. Maxillary palpi 5 — 6-, labial 2 — 3-jointed. Occiput margined. Clypeus rounded, usually discrete, marked with a punctiform impression on eacli side of the base. Antennae varying in length and in the number of the joints ; in Strcblocera geniculated and with an elongate scape ; in Eustaloccrus geniculated and clavate. Mandibles hardly bidentate. Mesothoracic sutures distinct or obsolete. Fore wings with 2 cubital areolets, sometimes obsolete ; pncdiscoidal often confused with the 1st cubital; radial either cult rate, reaching nearly to the tip of the wing, or minute, sub-lanceolate or semicordate, the metacarpus being then shorter or not longer than the stigma. Pobrachial areolet of the hind wings scarcely shorter than the prsebrachial ; praebrachial transverse nervixre sometimes obsolete. Abdomen petiolated ; suturiform articulation obsolete; segments 2 — 3 much longer than the rest, TRANS. ENT. SOC. LOND. 1887. — PART II. (.TUNE.) if
