SYNANTHEDON. By M. Gaede. 
S. melliniformis Lasp. Described from Saxony and dealt with in Vol. 2, p. 385, but not illustrated. 
An illustration is now being given (16 i). 
codeti. S. codeti Oberth. (16 e). According to Le Cere this is not a form of vespiformis, but a genuine species. 
atavus. A number of subforms are described. — atavus Le Cerf occurs at Sebdou in Algeria among typical specimens; 
inversa. the fore femora have wide yellow edges. — inversa Le Cerf (16 e) has base of forelegs yellow. The 4th to 
7th abdominal segments are yellow on underside with a black band at base. Forewings of typical colouration. 
The outer hyaline patch is said to be quadrangular, as wide as the black margin. In the $ the forelegs are 
quite black. The 3rd to 5th abdominal segments are yellow on underside, the 6th having only a few yellow 
scales. On forewings the disco-cellular is said to be somewhat narrower and the outer margin rounded at the 
hyaline patch. On upperside the abdomen of $ and $ has a yellow ring at base and at tip. Besides there is 
maroccana. a yellow belt on 5th segment which is wider in the + — maroccana Le Cerf. In both sexes there is a narrow 
yellow abdominal ring on the 2nd segment. In the $ there are a few yellow hairs on the last segment. The 
black scaling at outer margin of forewings is very wide, covering the fork in veins 7 + 8. It is bestrewn 
with pale yellow scales, so that the general impression is one of a grey colour. In the $ the 4th to 6th 
segments of abdomen are completely yellow on upperside. On forewings the hyaline patch extends beyond 
almohades. the fork of veins 7 + 8. A pair of this form has been captured. 15 mm. Cape Spartel. — almohades Le Cerf 
like the previous form, has 3 yellow bands on abdomen, but has a greater preponderance of yellow. The 
yellow dusting of the patagia is very heavy at their base and this extends to the centre of inner margin. 
Thorax is posteriorly entirely yellow. The 4th abdominal segment is yellow on upperside with black base, 
the edges of the 2nd segment are almost as bold as in the 6th. Fore wings correspond to those of typical 
codeti, having a wider dark marginal area than the outer hyaline spot. The inner edge of the marginal area 
is straight and it covers the fork of veins 7+8. The patagia of the $ less widely yellow. Thorax is 
black posteriorly, only a few yellow scales in centre. The 2nd abdominal segment is a deeper yellow on 
kabylaria. upperside. 15—20 mm. Cordoba, Granada. — kabylaria Le Cerf (16 d). This occurs at Constantine and like 
maroccana it has 3 yellow bands on abdomen and the base of forelegs in both sexes is yellow. It is larger 
than all the other races. In the $ the yellow scaling posteriorly on thorax is narrow. The edge of 2nd 
abdominal segment is narrower on upperside, that of the 6th segment consists only of a few scales, whilst on 
underside of last segment there are no yellow scales at all. On forewings the marginal area is only faintly 
dusted with yellow-red.* There is no yellow line at base of patagia. In the $ the thorax is anteriorly even 
less yellow than in the + The edge of the 6th segment is as narrow 1 as that of 2nd, the band on 4th segment 
is narrower in the centre. On underside the 4th and 5th segments are only half yellow, the edge of the 6th 
is as narrow as on upperside. 18—22 mm. — In typical codeti Oberth. the 4th and 7th segments of abdomen 
are yellow with black base on upper and undersides, the 6th is only in exceptional cases edged delicately 
with yellow on upperside. On underside the middle of the 5th and 6th segments is yellow. In contrast 
in the $ the 4th segment of abdomen is completely yellow on upper and undersides, the 5th and 6th only 
having a yellow edge on underside. — In regard to the food plant a mistake was made in Vol. 2, p. 385, 
it should have read tamarisk and not tamarind. 
icingulata . S. myopaeformis Bkh. (Vol. 2, p. 385, pi. 51 e). - bicingulata Rbl. has also base of abdomen red, whilst in 
the type only the 4th segment has a red belt. 
S. cruentata Mann (Vol. 2, p. 387, pi. 52 a). We have to add here the name mutillaeformis Godt. to 
the synonyms. Among the many specimens bred from Catania, where the species is common, there are 3 
with scarcely any red scales on centre of abdomen. The forelegs are black and in one instance the white 
lugubris. colouration of the tip of the antennae is absent: lugubris Ragusa. 
tlieryi. S. theryi Le Cerf (16 cl). Antennae black on upperside, on outer edge and on underside reddish yellow, 
except at tip. Thorax with a few yellow dots. Abdomen black-blue on upperside. The 4th and 7th segments 
quite yellow, the 2nd and 6th with wide yellow edges. Anal brush with 3 tufts, yellow in centre. Underside 
yellow, only the anterior half of the 4th and the base of the 8th segments black. Wings hyaline and very 
elongate. Veins and margins black. The disco-cellular narrowly orange red. On hindwings the veins are 
delicately black. Legs black and yellow. 18 mm. Algeria. 
insidiosa. S. insidiosa Le Cerf. Very like velox Christ. (Vol. 2, p. 388, pi. 51 e). Antennae, palpi and body black. 
The 4th and 6th abdominal segments with narrow white edges on upperside. Wings hyaline. There is a 
snow white spot at base of forewings. Veins and margins blue-black. The disco-cellular outwardly with 
orange red spot. Similar coloured scales at base of cell and at inner margin. On hindwings the base is 
somewhat more widely black. Veins and margins narrowly black. On underside the forewings are suffused 
with pale yellow, the disco-cellular of hindwings is orange red on upperside. Legs black, hind tibiae with 
a few orange red hairs. $ 20 mm. Nanshan. 
mimus. S. mimus Le Cerf (16 e). Very close to andrenaeformis Lasp. (Vol. 2, p. 383, pi. 51 d). Antennae blue- 
black on upperside, brown underneath. Thorax blue-black, collar with yellow scales at the sides. Abdomen 
blue-black, the 2nd, 4th and 7th segments with pale yellow edges on upperside. There are also yellow hairs 
in centre of anal tuft. On underside the 4th to 6th segments are completely white, the 8th yellow. Legs black 
with white patches.
