A remarkable form of Scoliides, with wings of smaller size than usual and deeply divided, has been described by Saunders under the name _Pseudomeria graeca_. Still more remarkable is _Komarovia victoriosa_ found in Central Asia; in this Insect the male retains the appearance of a slender, pallid _Scolia_, but the female differs totally in form, and has the peculiar wings so reduced in size as to be useless for flight. SUB-FAM. 4. SAPYGIDES.—_Closely allied to the Scoliides, but possessing slender legs and antennae; also the first abdominal segment is less disconnected from the second, so that the outline {100}is less interrupted; the eyes are deeply emarginate; the hind body is not spinose at the apex._ [Illustration: Fig. 41.—_Sapyga 5-punctata_ ♀, Britain.] The economy of _Sapyga_, the only genus, has been the subject of difference of opinion. The views of Latreille and others that these species are parasitic upon bees is confirmed by the observations of Fabre, from which it appears that _S. 5-punctata_ lives in the burrows of species of the bee-genus _Osmia_, consuming the store of provisions, consisting of honey-paste, that the bee has laid up for its young. According to the same distinguished observer, the _Sapyga_ larva exhibits hypermetamorphosis (_i.e._ two consecutive forms), and in its young state destroys the egg of the bee; but his observations on this point are incomplete and need repetition. We have two species of _Sapyga_ in Britain; they differ in colour, and the sexes of _S. 5-punctata_ also differ in this respect; the abdomen, spotted with white in both sexes is in the female variegate with red. Smith found our British _Sapyga 5-punctata_ carrying caterpillars. SUB-FAM. 5. RHOPALOSOMIDES.—_Antennae elongate, spinigerous; ocelli very prominent; tarsi of peculiar structure, their claws bifid._ [Illustration: Fig. 42—_Rhopalosoma poeyi._ A, female imago; B, front of head. Cuba. (After Westwood.)] This sub-family has recently been proposed by Ashmead[47] for {101}an extremely rare American Insect that had previously been placed by Cresson among parasitic Hymenoptera. Westwood classed _Rhopalosoma_ among Diploptera, saying of it "animal quoad affinitates excrucians." We reproduce Westwood's figure, but not being acquainted with the Insect we can express no opinion as to whether it is allied to the Scoliidae or to the Sphegidae. The habits are, we believe, quite unknown. FAM. 2. POMPILIDAE. _Pronotum at the sides reaching the tegulae; hind body never definitely pedicellate, though the first segment is sometimes elongate and conical; hind legs long; eyes elliptic in form, not emarginate._
