the abdominal ones, all of them being similar in size (d=80-95fim). Atrium walls formed of rings and irregular polygons with spinules (Fig. 8). Integument spinulous on its dorsal and pleural parts (Fig. 9),practically smooth on the ventral part. The spinules (1=5-1 Oum) are replaced by papillae on pleural lobes and on transversodorsal bands situated on the centre of each segment. Papillae numerous and slightly coloured. Papulous areas of the integument with tiny setae (1-5-10 jum) (Fig. 10), which are also present, though less densely, on other areas. Head (Fig. 11) - Slightly wider than high (w=0,99 mm, h=0,93 mm). Parietal bands present (1=0,23 mm). Integument fairly smooth, with tiny setae (1=5 urn) on the clypeus, on the surface of the integument contiguous to mandibles and in the proximity of the antenna! orbits and upper part of the head. Antennái orbits (Fig. 12) (d=40 jun) slightly ellipsoid, with three sensory cones (d-5 urn). Anterior edge of clypeus (w=0,46 mm, h=0,22 mm) slightly emarginated. Labrum (Fig. 13a) (w-0,38 mm,h=0, 185 mm)with sparse punctures, from some of them arising minute setae. Anterior end deeply emarginated. Epipharynx (Fig. 13b) with numerous spinules (1=5-1 O^um) on its lateroinferior area, directed downwards. Sensory areas on the central area with 6-7 sensitive papillae (d«5jum) on each side. Mouthparts - Mandibles (1=0,371 mm, w=0,l 76 mm) with four characteristically-shaped teeth; basal tooth split at tip. Interior part of upper face exhibiting a group of 20-25 spinules (l=5/tm). Maxillae (Fig. 14) (1=0,39 mm, w=0,185 mm) with spinulous lacinial area. Galeae (1=65 ,um, w=45 < um) considerably larger than the maxillary palpi (1=45 urn, w=35;um), with tiny papillae at the apex. Labium (Fig. 15) (w=0,42 mm,h=0,l 9 mm) with setae (1=1 O^mjon its oral face.Lips of spinneret about 0,29 mm in width. Labial palpi (l=40<um, w=30/im) slightly smaller than the maxillary ones. DISCUSSION Among the larvae studied until the present belonging to the genus Sphex LINNAEUS, 1758, those of Sphex rufocinctus have fairly common characteristics with Sphex inusitatus fukuianus TSUNEKI, 1957 - described by IiDA (1967) - such as the appearance of the integument with papillae and spinules, the size of many of the cephalic structures - mandibles, galeae, maxillary palpi, antennái orbits -, the aspect of the epipharynx and the smaller size of the thoracic spiracles compared with the abdominal ones. However, certain differences can be seen, such as the presence of tiny setae on the integument of Sphex rufocinctus, the form of the head and of the antennái orbits and the punctures on the front of the head and of the clypeus, that is denser than in the species reported by IiDA. Other species with which Sphex rufocinctus shows morphological similarities are Sphex ichneumoneus (LINNAEUS, 1758), Sphex tepanecus SAUSSURE, 1867 and Sphex argentatus formosus KOHL, 1890, although such similarities are much less patent than those it shares with Sphex inusitatus fukuianus. The larvae of the genus Ammophila W. KIRBY, 1798 described until now (EVANS 1959,1964; EVANS & LIN 1956, GRANDI 1926, IIDA 1967, TSUNEKI & IIDA 1969) differ above all in their mandibles, the epipharynx and the antennái orbits. The main differences between Ammophila laevicollis and the rest of the species lie in the fact that the central part of the epipharynx of this species has no spinules, while these do appear in the other species, and that the integument has setae on its surface; these setae have only been reported previously in Ammophila campestris LATREILLE, 1809 (GRANDI, 1926) and Ammophila formosensis TSUNEKI, 1971 (=Ammophila clavus formosana TSUNEKI, 1967 [TSUNEKI & IIDA 1969]). The spinules appearing on the upper face of the mandibles are scarce in comparison with those observed in the rest of the species, their aspect resembling those found in Ammophila hard (FERNALD, 1931).
