We reproduce from Zittel's handbook a figure (Fig. 162) of one of these gigantic Insects, and add an attempt at a restoration of the same after the fashion of Scudder (Fig. 163). From these figures it will be seen that the relation to our existing Phasmidae must at best have been very remote.[204] It will be noted that the larger of the two figures is on a ⅕ scale. The classification of Phasmidae was left in a very involved state by Stål, but has recently been brought into a more satisfactory condition by Brunner von Wattenwyl. We give a translation of his table of the tribal characters:— 1. Tibiae beneath carinate to the apex, without an apical area. 2. Antennae much longer than the front femora, many jointed, the joints being above 30 in number and only distinct at the base and towards the apex.[205] 3. Median [true first abdominal] segment much shorter than the metanotum.[206] The species all apterous. 4. The anal segment of the males roof-like, more or less bilobate. The female has a supra-anal lamina. The species inhabit the Old World. Tribe 1. LONCHODIDES (Fig. 148, _Lonchodes nematodes_.) 4′. The anal segment of the males arched, straight behind. No supra-anal lamina in the female. The species are American. Tribe 2. BACUNCULIDES. 3′. Median segment as long as, or longer than the metanotum. Species with the male or both sexes winged. 4. Females apterous or rarely possessed of short wings.[207] Males winged. Femora dentate beneath, or lobed, or at least armed with one tooth. Species occur both in America and in the Old World. Tribe 3. BACTERIIDES. (Fig. 162, _Palophus centaurus_.) {278}4′. Each sex winged. Femora smooth beneath. The species belong to the Old World. Tribe 4. NECROSCIDES. (Fig. 159, _Calvisia atrosignata_.) 2′. Antennae (at any rate in the females) shorter than the front femora, the joints distinct, not more than 28 in number. The species belong to the Old World. 3. Median segment shorter than the metanotum. Apterous species. Cerci plump. Tribe 5. CLITUMNIDES. (Fig. 160, _Eurycantha australis_.) 3′. Median segment longer than the metanotum. Species usually winged. Cerci (except in some genera of the group _Platycraninae_) flattened, elongate. Tribe 6. ACROPHYLLIDES. (Fig. 153, _Cyphocrania aestuans_.) 1′. Tibiae furnished beneath with a triangular apical area. 2. Antennae many jointed, longer than the front femora. 3. Median segment shorter than the metanotum. Apterous species.[208] 4. Either head, thorax, or legs spiny or lobed. Tribe 7. CLADOMORPHIDES. (Fig. 149, _Heteropteryx grayi_.) 4′. Head, thorax and legs unarmed. Tribe 8. ANISOMORPHIDES. (Fig. 161, _Anisomorpha pardalina_.) 3′. Median segment longer than the metanotum.
