388 SYNANTHEBON. By M. Bartel. 



with a largo outer vitreous area divided into 5 spots. The cross-vein of the hindwing considerably more incras- 

 sate. No white borders to the eyes. Palpi black-blue. Patagia red inwardly. Abdominal segment 4 entirely 

 red above, the sides of 5, 6 and in o also 7 are spotted with red; beneath the last 3 (in ,^ 4) segments red. 

 Anal tuft of (J with lateral yellowish stripes. Breast without red spot near base of wings. Legs blue-black, tarsi 

 yellowish. Distributed over the greater part of Central Europe, North Italy, South France, Spain, Portugal, 

 East Ruinelia, Volga and Ural districts, Transcaucasia and Asia Minor. — In the latter country, in Syria and 

 amasina. North Persia it is represented by the form amasina Stgr., in which the proximal vitreous spots are reduced, 

 the outer vitreous area consists of only 3 spots and the dark scaling on the cross-vein of the hindwing is broader. 

 Moreover, the belt of the abdomen is orange-red above, dirty yellow beneath, similarly coloured atoms being 

 present on segments 5 and 6 on underside. More rarely is the belt the same colour all round, spreading over the 

 underside of segments 5 and 6. — Larva in Medlar (Mespilus germanica); moth from May to the end of July. 



velox. S. velox Fixs. (51 e). Differs from sto)noxyformis in the narrower median band of the forewing, in the 



cross-vein of the liindwing only being scaled in the upper half, the band of the forewing being scaled golden 

 yellow beneath, the palpi wliite-hairy with the first segment entirely white, the second blackish on the upper 

 portion of the outer side, and the third entirely black. Further, the eyes are bordered with white anteriorly; 

 segments 4 and 5 of abdomen are red; the anal brush shorter, red mixed with blackish; legs with green sheen, 

 the rings on the tibiae and tarsi as well as the spurs white. Expanse 26 mm. — Corea (Pung-Ting, middle of 

 August). 

 polaris, S. polaris Stgr. Abdomen uniformlj' black without coloured belt. The outer vitreous patch of the fore- 



wing traversed by 4 veins, being higher than broad. Distal border of hindwing narrow, black. Palpi black, 

 yellowish red on inside and beneath. Antennae blue-black, exteriorly and anteriorly with a very slight yellow 

 suffusion. The last abdominal segment beneath and the anal tuft on the sides with long yellowish red hair. 

 Breast with some red scales on the sides. Tibiae yellow on inside; tarsi almost entirely yellow. Costal margin, 

 median band and outer border of forewing brownish black, hind margin entirely reddish; above the outer vitre- 

 ous patch a red streak and on the outer border reddish scales. Cross-vein of hindwing anteriorly much tlucker 

 than in culiciformis. On the under surface the costal margins of both wings extended yellow-red, the outer 

 area of forewing with 6 yellow-red small wedge-streaks, and the veins of hindwing suffused with yellow-red. — 

 Hitherto only found in Central Norway (Dovrefjeld), Lapland (Lule), Kuusamo andPohjois-Pohjanmaa (Fin- 

 land) and in theKenteiMts. ; but probably distributed over the whole of Northern Europe and Asia. The larva 

 is said to feed in Dwarf Birch (Betula nana). 



iormUac- S. formisaeformis Esp. (51 f). Median band of forewing black, wdth a tliin brown-red outer border. 



formis. Xhe whole outer area a beautiful brown-red, costal and hind margins dusted with brown-red. Antennae black. 

 Frons with wliite bands before the eyes. Palpi red, black on outside. Abdominal segment 4 above entirely 

 red, 5 partly so; beneath, segments 4 and 5 entirely and 6 partly red. Anal brush with whitish stripes on sides 

 in ?; in o yellowish, the apex of the lateral portion yellowish beneath mixed with yellowish. Breast without 

 coloured spot. Legs black, tarsi yellowish, mid tibia with one and hind tibia with two whitish yellow rings. ■ — 

 Distributed throughout Europe (excepting the Polar countries), Central Ural, Asia Minor, Transcaucasia, Siberia 

 to Amurland. Specimens from the Lena district (Ytyk-haja, July 5) have the distal border of the forewing 

 blackish. Larva wliitish yellow, on the abdomen with feeble longitudinal line shining through, on the last seg- 

 ment two wart-hke tubercles each of which hears a small hair, and on each side with 3 rows of tliin short hairs 

 placed on granules. Head red-brown, pronotum paler, the former with bristly hair. The outer margin of the 

 mandibles forms a portion of a circle, the inner margin bearing before the apex 3 triangular teeth of equal size. 

 On the anal legs a brownish spot. Lives until May in the low stumps of cut-down bushes of Salix, especially 

 in the stumps of osiers cut the year before, up to 2 feet above the ground, and also in the stems and branches 

 entirely dwarfed bushes of Salix. Hibernates once and turns in April or May in the tunnel into a yellowish 

 brown pupa. The moth from May until August, chiefly in June. The larva, according to Gross and Sorhagen, 

 Nalso lives in the goiter-like swellings of the younger trees and branches of Sallow (Salix caprea) in sunny loca- 

 lities; but it is has not been ascertained if the abnormal growths are due to the larvae. 



serica. S. serica Alph. (50 g). Distinguished from formicaeformis by the uniformly coppery red median band 



of the forewing. Distal border narrower than in the previous species. Fourth segment of abdomen entirely cop- 

 pery red, third segment with slight red scahng. Yellow colouring of liind tibia stronger and brighter. — Kuldja 

 district, end of May, 1 ,^ at Kunges, 4000 ft. 1 ^ and 1 $ from Uralsk (June) agree well with the original 

 description, only the red belt occupies ventrally segments 4 and 5; these specimens are smaller, 17 — 18 mm, 

 and conspicuously red at the base of the forewing. 



nihonica. S. nihotiica spec. nov. (50 g). Herr Fr. Scbiba has kindly sent me for description a cJ and a $ which has 



a different facies from the other known species of this genus and are doubtless closely related to the Indian 

 genus Ichneumonoptera Hamps. However, vein 2 of the forewing is not absent in them, but approaches 3 

 very clos?ly. Palpi with the end-segment long and pointed. Antenna of o "«ith short cilia. Hind tibia of $ 

 rather strongly hairy. Anal tuft very long, in S very strongly pointed and folded together. Veins 7 and 8
