•BEMBECIA; SYNANTHEDON. By M. Bartel. ^hi 



head and legs orange-yellow, with a few black scales. Antennae orange, in cj bipectinate. Collar and thorax 

 black, the former as well as the patagia and the nietanotum margined with yellow. Abdomen blue-black, 

 each segment with a pale yellow belt. Anal tuft black and orange. — Murree; not yet found on Palearctio 

 territory, only occurring near the boundary. 



5. Genus: Bemlieeia Hbn. (1822). 



Antennae short, pointed, without small bristles at the tip, in $ filiform, feebly notched, in ^J bi- 

 pectinate excepting the apex. Palpi small, clothed with long bristly hair, much stronger in ,^ than in $. 

 Eyes relatively small. Proboscis very short, horn;y. Tibiae with tufts of hair at the apices. Abdomen stout, 

 narrowed at base, incrassed apically, very robust in $, slenderer in (J ; segment 3 above in centre with a 

 conspicuous tuft of hair, a smaller one above on next segment. Anal tuft of both sexes short and broad, longer 

 in the cj. Forewing very narrow, veins 4 and 5 coincident, and 7 and 8 very long. Hindwing narrowed, 

 with the cross-vein unsealed and directed obliquely outwards; vein.s 3 and 4 on a long stalk, 1 a extending 

 to tiie distal margin. — The moths fly at night and rest with the wings lying flat on the body. The larva 

 is cylindrical, of even thickness, sparsely covered with minute hairs, and lives in Raspberry. — Type: B. 

 hylaeiforin /.y Las p. 



B, hylaeiformis Lasp. (52 e). The extei'ior vitreous area of the forewing is sharply bounded distally. hylaeifor- 

 First and second segments of palpi black outwardly and at the tip. Segments 1, 2 and 3 of abdomen ""*■ 

 with narrow anterior yellow belt and 3 also with posterior belt; posterior margins of segments 4, 5, 6 and 

 ill J also 7 almost with broad yellow belts of almost even width. Anal segment never ejitirely yellow. 

 Anal tuft for the greater part yellow, sometimes the black colour preponderating. In specimens from Amurland 

 the tuft is black with yellow centre, and in (^ sometimes altogether black. Fore coxa black, only yellow at the 

 base. Central and Northern Europe (with the exception of the Arcti: districts, also not known from England 

 and the Netherlands), northward to Saltdalen in Nordland, and Finland, southward to Portugal, Piedmont 

 and Dalmatia, Asia Minor and probably from Kasan over Siberia to Amurland, having already been recorded 

 from the last districts. The full-fed larva 25 — 30 mm long, whitish grey, bearing single small grey hairs, the 

 head brownish yellow, some spots on the pronotum yellow, as is also the anal tergite; thoracic legs yellowish, 

 jjrolegs with dark border. Hibernates once and lives until May or June in roots of Raspberry (Rubus idaeus), 

 more rarely in Blackberry; after hibernation it moves into last years stalks, which easily break off when ^ 

 being shaken. Pupa brownish yellow, wath flat head-point, two rows of small hooks on each abdominal seg- 

 ment and 6 — 8 small spikes at the truncate anal end. Moths from June until August, usually after the middle 

 of July, rarely still early in September; flies at night. 



B. pectinata Sfgr. (52 f). Differs from B. hylaeiformis in the outer vitreous area of the forewing pgc/jna^i. 

 not being sharplj^ bounded distally, the antennae having longer pectinations and a more pointed tip, and 

 the palpi being almost entirely yellow. Abdomen dark, segments 1 and 2 without yellow colouring and 

 this very slight, all the other segments with yellow hind edges, on 4, 6 and in ^ also 7 the yellow borders 

 usually remarkably broader than on the other segments. Anal segment entirely yellow in 9- Anal tuft 

 predominantly yellow in (J and entirely yellow in $. Anterior coxa almost entirely yellow. Femora black, 

 with the inner edge yellow. Tibiae and tarsi red-brown, mixed with black. — Kentei Mts. and Southern 

 Amurland, the end of July and early August. 



B. fixseni Leech (52i). Forewing partly vitreous, densely covered with reddish brown scales along the fixscni. 

 veins to the apex of the cell. Apex and the broad outer border deep leather-brown. Hindwing vitreous, with 

 deep brown dark distal margin. Head black. Palpi yellow. Collar narrowly yellow. Antennae above blackish, 

 beneath reddish. Thorax with the inner edges of the patagia and a spot above and another below yellow. 

 Abdomen blackish, with 4 yellow transverse bands on the 4 last but one segments; anal segment entirely 

 yellow; anal tuft reddish orange. Legs yellow. Forewing marked with reddish orange. Underside of forewing 

 yellow along the veins and towards the apex. Hindwdng irrorated with yellow along the outer margin. Expanse 

 42 mm. — Japan (Nikko, Oiwake, June, July). Placed by Leech into Sphecia. but appears to agree better 

 with the species of Bembecia; not known to me in nature, perhaps only a synonym of pectinata Stgr. 



B. odyneripennis Walk. (50 m) was described from Nova Scotia. Leech, however, records it also from odymri- 

 Japan (Hakodate, August), which may be due to a confusion witli some other similar species. The figure V""^"- 

 taken from the type renders a description unnecessary. 



6. Genus: N.ynaiitliedoii Hbn. (Sesia aut. pr. p.) (1822). 



Slender moths with well-developed proboscis. Antennae incrassate before the apex, bearing small 

 bristles at the tip, in $ notched and ciliated. Palpi slender, with short terminal segment, the basal segment 

 hairy beneath. Anal tuft strongly developed in both sexes. Forewing ahvays with 3 vitreous areas, of which 

 the longitudinal area reaches at the inner margin to the median band or beyond it. The wedge-spot in the 

 cell very large, and the outer vitreous patch consisting of several partitions. In the forewing veins 10 and 11
