the $ sex having the same yellow patches on thorax and abdomen. The $ is relatively small. 'I horax has no 
yellow spots on upperside. On abdomen the yellow belts are absent on the 1st, 4th and 5th segments on the 
upperside. The 2nd and 3rd have equally wide lateral yellow edges, the 6th and 7th are quite yellow. Both 
in and $ forewings have a narrow long vitreous strip in and below the cell. N. Africa. — diaphana Schaw. diaphana. 
Four specimens of this have been captured in Bosnia. The yellow patches of body are slightly paler than usual. 
Forewings are hyaline. Only the costa, inner margin and disco-cellular being reddish yellow. Outer margin 
and fringes pale brown. 
P. aurantiacum Rbl. Somewhat similar to tabaniformis Rott. (Vol. 2, p. 380, pi. 51 b). Antennae long, aurantia- 
orange yellow, the lamellae black, brownish at tip. Palpi yellow and orange. Collar yellow at the sides. 
Patagia with narrow yellow edge, a yellow spot at base of forewings. The 2nd, 4th and 7th segments of 
abdomen with yellow edges. The 3rd segment is yellow underneath. Fore femora yellow outwardly, otherwise 
the legs are orange yellow. Forewings narrow, dull orange with black veins and margin. r l he cuneiform 
and longitudinal areas are narrow and short, somewhat hyaline behind the cell above vein 3. Hindwings 
vitreous, disco-cellular orange yellow, the other veins yellow-brown. On underside the scaling of both wings 
is pale orange yellow. £ 32 mm. Amanus mountains. 
P. insolitus Le Cerf (16 d). Body black. Thorax and patagia with a few yellow dots. The 2nd, 6th insolitus. 
and 7th segments of abdomen with yellow edges. Anal tuft with a few yellow hairs. On underside all segments 
with yellow edges. Legs predominantly yellow. Forewings reddish brown, black towards base, with a yellow 
basal spot on costa. A long narrow hyaline streak in and below the cell. In outer area a similar vitreous spot 
between veins 3 and 4. Hindwings hyaline, veins and marginal line delicately reddish brown. Underside 
of forewings paler yellowish. <$ 30 mm. Akbes. 
P. davidi Le Cerf. Body longer, similar to bicincta Wkr. (Vol. 2, p. 380, pi. 50 k). Body metallic black, davidi. 
Abdomen with narrow yellow edges on 2nd and 4th segments. Anal tuft with a few white hairs at sides. Fore¬ 
wings blackish brown. The areas in and below the cell are hyaline, diffusedly so up to the end of cell. Hind¬ 
wings quite hyaline with finely marked black disco-cellular and margin. Differing only materially from 
bicincta Wkr. by the slight vitreous area in forewings. $ 27—29 mm. Moupin. 
P. pernix Leech. The species was described by the author as a Rembecia. In Vol. 2, p. 409 it was pernix. 
placed under the Chamaesphecia. According to Le Cerf it should be placed here and it can be described as 
a davidi with somewhat different belts on abdomen. 
P. daisensis Mats. Similar to ferale Leech (Vol. 2, p. 380, pi. 51 d). Black-blue. Tegulae with orange daisensis. 
yellow anterior edge. The 4th segment of abdomen with wide orange yellow band, a narrower one at sides 
of 2nd segment. On forewings there is a narrow subhyaline stripe in the cell and a shorter one below same.

Abdomen metallic steel blue. An orange yellow belt on 4th segment expanding on underside. Legs black- 
brown. In $ the antennae are serrate. <§ 38 mm. Hokkaido.

dominal segments with a whitish yellow band, a white lateral mark on 6th segment. Legs dark with }ellov 
patches. Forewings dark brown, coppery brown in centre. The veins and clisco-cellular darker. Hindwings

6. Genus: Syiiantlietloii Hbn. 
S. flaviventris Stgr. (Vol. 2, p. 384, pi. 51 d). This species is also found in England, partly in typical 
specimens, partly in aberrative forms. In the latter the black patches of fore wings are more or less densely 
dusted with orange yellow. This occurs at base, costa, inner margin and especially heavily on disco-cellular. 
At outer margin however there are only traces of yellow scales: fulva Trnr. fuha. 
S. cephiformis O. (Vol. 2, p. 384, pi. 51 d). In fumosa SchiUze the usually yellow patches on body, fumosa, 
palpi and legs are a brown-yellow. The hairs at base of both wings are grey. This form was once hied in Saxon} , 
a number of specimens being obtained. 
S. conopiformis Esp. (Vol. 2, p. 385, pi. 51 cl). Specimens from Vendee in which the yellow belts on 
abdomen and the yellow legs are about as striking, as illustrated in Vol. 2, pi. 51 f for ichneumon ifo) mis, aie ^ ^ 
named: lucasi Le Cerf (16 e). 
S. vespiformis L. (Vol. 2, p. 385, pi. 51 e). — polycincta Le Cerf (16 e) is a similar variety to lucasi just polycincta. 
described above. On abdomen of the R the yellow bands are closely compressed together, only at base a stretch 
is free of them. This form is found in Spain.
