Diagnosis (from illustration). Large costal area with branched veins. Sc and R close (it is difficult to see in the illustration if they join); Scudder wrote that they 'approach each other very gradually'. Rs has about 18 branches. Holotype. , Durdlestone Bay, Dorset; Brodie colln (specimen not traced). Purbeck. Dimensions: 13 mm x 9mm, estimated wing length 15 mm. Discussion. This species is retained in the genus Pterinoblattina pending examination of the holotype. There are, however, some basic differences between Scudder's figure of P. penna and P. pluma; for example, the figure shows many more branches on the radial sector vein and that the costal veinlets are clearly Fig. 10 Pterinoblattina penna Scudder. Vena- tion, from Scudder, 1886: fig. 14. Family KALLIGRAMMATIDAE Handlirsch, 1906 This is a group of large (wingspan 80-200 mm) neuropterous insects in which the hind wing is narrower than the much-enlarged forewing. The costal area is twice as wide as the subcostal and radial areas together. Cross-veins are usually numerous and a large eye-spot is often present on the forewing. Apical branches of MA form rows in front of MP, running to the outer (terminal) margin. Genus PARACTINOPHLEBIA Handlirsch, 1906 1906 Paractinophlebia Handlirsch: 477. Type species. Pterinoblattina curtisii Scudder, 1886, by monotypy. Discussion. This genus was proposed by Handlirsch for an in
