XX PANORPIDAE HEMEROBIIDAE 453 Boreus and Bittams were also observed by Brauer; they are essentially similar to those of Panorpa, but the larva in Boreus is not provided witli abdominal prolegs. The Panorpidae have been separated from the other Neuroptera by certain naturalists as a distinct Order, called Panorpatae by Brauer, Mecaptera by Packard; but in their structure as well as in their metamorphoses they are not so distinct from the Phryganeidae and the Hemero- biidae as to justify this step. Possil forms of Bittacus and of Panorpa have been found

Possil forms of Bittacus and of Panorpa have been found in amber and in the Tertiary strata, and Scudder has described some forms from Florissant in which there are no cross-veinlets in the wings. Some remains from the English Lias have been referred to Panorpidae by Westwood under the name Orthophlelia, but it is by no means certain that they really belong to the family. Fam. X. Hemerobiidae—Ant-lions, Lacewing-flies, etc. Head vertical; maxillae free, with Jive-Jointed palpi ; labial palpii three-Jointed. Wings suhequal in size, with much reticula- tion, without anal area. Tarsi Jive-Jointed. Metamorphosis great; the larvae with mandibles and maxillae coadapted to form spear-like organs that are suctorial injunction. Pupa, similar in general form to the imago, enclosed in a Fig. 298.—Drepanepteryx phdlaencndes. Scotland. The Hemerobiidae are an extremely varied assemblage of Neuroptera; the perfect Insects of the various sub-families are very different in appearance, but the family as a whole is naturally defined by the very peculiar structure of the mouth- oro-ans of the larvae. These Insects have, in fact, a suctorial.
