SYNANTHEDON. By M. Bartel. 383 



in ,^ like the following segments almost entirely yellowish white, in $ yellowish. Anal tuft slightly margined 

 with vellow. Fore coxa extended yellow on outside. Legs very pale only on the inner side, predominantly 

 black on outside; hind tibia very slightly mixed with a paler colour at the base and apex; tarsi with a strong 

 dark suffusion. ■ — Amurland (early July). 



S. bicingulata Stgi . (51 d). Similar to spheciformis and niemueformis, but the forewing narrower, with bicingulaUi. 

 much narrower median band than in the former. Cross-vein of hindwing slightly incrassate by scaling only in 

 the upper portion. Antennae above uniformly black-blue, first segment beneath yellow. Frons golden 

 brown, with white bands in front of the eyes. Head with narrow yellow posterior margin. Palpi yellow, 

 with the outer half black. Patagia with yellow inner border. Segments 4 and 5 of abdomen above with 

 broad yellow- belts, which are widest at the sides, segment 1 laterally spotted with yellow, 2 with single yellow 

 scales at the hind margin, 4, 5, 6 and in ^ also 7 entirely yellow beneath, only the last segment bearing 

 some black in the centre. Anal tuft above yellow at the tip, beneath extended yellow. Legs black; fore 

 coxa with broad yellow suffusion on outside; hmd tibia yellow at the base and apex; tarsi nearly entirely yellow. 

 Legs of $ predominantly yellow. ■ — Amurland (late in July). In a $ before me from coll. PItngeler the longi- 

 tudinal and wedge-shaped patches of the forewing are slightly suffused with brown, and the hind margin of 

 the forewing is almost entirely scaled yellow. 



S. hector But!. (51 d). Similar to spheciformis, but the antennae without white spot above, being heclor. 

 uniformly black, and the frons bearing white bands in front of the eyes. Hind margin of head yellow beneath 

 and at the sides. Thorax uniformly black-blue, without yellow stripes. Abdomen slightly striped with yellow 

 on the sides of segments 1 and 2, segments 4 and 5 above with very thin yellow belts. Anal brush black- 

 blue, slightly mixed with brown. On the underside .segments 4 and 5 occupied by two broad, golden yellow, 

 almost united stripes. Anterior coxa exteriorly yellow; hind tibia with a yellow ring in the middle and at the 

 apex; tarsi yellowish grey. Wings narrower and darker than in spheciformis, with black-blue margins. Cross- 

 vein of hindwing onty incrassate by scaling in the upper half. The costal margin of the forewing dark, only 

 the base being slightly pale in colour. — Japan (Yokohama, Oiwake). 



S. tenuis Biitl. (51 c). Wings transparent, with the margins and veins black; beneath both wings Ifnuis. 

 with bronze-coloured costal margin. Body steel-blue. Collar and two thin abdominal belts silvery white. 

 Palpi, anterior side of coxae, sides of breast, basal segment of abdomen and a ventral band silvery white. 

 According to Butler allied to minellata Zell. — Japan (Yokohama, Oiwake). 



S. unocingulata spec. nov. (51 d). Belongs to the relationship of bicingulata Stgr., bearing like that uno- 

 species white bands in front of the eyes. But the antennae are uniformly black-blue, and the uniformly black- <^"mdala. 

 blue abdomen only bears a broad yellow belt at the apex of segment 4, which is continued across the under- 

 side. Palpi black, whitish on inside. Head beneath edged with white. Forewing with narrow black borders; 

 median band one-half narrower than in spheciformis, the distal area also is narrower than in the latter species. 

 Hindwing with very thin dark border; cross-vein slightly incrassate anteriorly. Legs black-blue, tarsi mixed 

 with yellow; hind tibia with a yellow ring in middle and at apex. Anal tiift laterally slightly mixed with 

 yellow. Expanse 24 mm. (1 9)- — Japan. 



S. sodalis Pilng. (50g). Herr R. Pxjngeler has kindly lent the type for figuring and sent the following sodalis. 

 description: "Expanse 24 mm. Similar to spheciformis Gem., but abdomen with a whitish belt on segment 4 

 instead of on segment 2, and dirty yellow underside. Antenna more strongfy ciliate and without yellow, 

 likewise the palpi and legs dark. — North Tibet: Kuku-Nor, 1 ^ (RtrcKBEiL)". Type in coll. Ptjngeler. 



S. andrenaeformis Lasp. (51 d). This is the first species of a group of small forms whose larvae live andrenac- 

 likewise in trees and shrubs. S. andrenaeformis is especially distinguished from the following allied species lormis. 

 by the absence of the white bands in front of the eyes, by the patagia not being edged with yellow at the 

 dorsal margin, and the abdomen being ringed with yellow only on segments 2 and 4. Anal brush of c^ orange- 

 yellow in the middle and at the tip, in 9 only strongly mixed with yellow at the apex. Abdominal segments 

 1 and 2 spotted with yellow on the sides. Abdomen of the ^ distinguished from that of the allied species 

 by being strongly compressed laterally; it bears a very long anal tuft and the segments 4 — 6 and the 

 dorsum of 7 are glossy silvery w hite : in 9 only the edge of segment 4 is broadly and that of 5 narrowly white 

 or yellowish, 6 sometimes posteriorly also with vestiges of yellow colouring. Rarely are also in 9 segments 

 4 and 5 entirely silvery white. Palpi whitish or yellowish, black on outside. Distal area of forewing wath 

 a reddish sheen. In ( ? ab.) monedulaeformis Bdv., from Andalusia, the abdominal belts are paler yellow-, imnedulae- 

 the anal brush also being yellowish white. — From Great Britain, Belgium, Austria-Hungary, Bosnia, Carinthia, formts. 

 Switzerland, South-Eastern Russia and the adjacent districts of Asia, of Eastern Russia and Asia IMinor. 

 The larva lives in the small stems of Snowball (Viburnum lantana, rarely in V. opulus) according to Roth- 

 schild (Trans. Ent. Soc. Lond. 1906 p. 471). At the place quoted the habits, caterpillar and chrysalis 

 are described in great detail. The larva bores a straight tunnel in the centre of the stems or branches of 

 the food-plant, and pupates without cocoon at the end of the tunnel, which almost stands at a right angle 

 to the central tunnel. The moths emerge from the middle of May until July.
