belts; in $ a large triangular yellow spot on segments 2, 4 and 5. Aiial tuft yellow, black at the sides. An- 

 terior coxa ochreous or whitish ; mid and hind tibiae ochreous, with a broad black rmg at the base and apex. — 

 Southern France, Spain and questionably also Algeria; in May and June. 



Ch. staudingeri Failla (50 1). C'lumsier in build than anrieUata with broader forewing, and easily slaudingeri. 

 distinguished by tiic belts on the underside of the abdomen not being so distinctly continuous. Larger than 

 alysoniformis. Forewing with a light spot at the base and two very small hyaline patches; wedge-spot vestigial, 

 anteriorly bordered with pale yellow; outer hyaline patch tripartite. The small markings in the outer area 

 very obsolescent. Cross-vein of hindwing strongly incrassate throughout. The eyes with white anterior border. An- 

 tennae black, yellowish on outside, first segment light yellow beneath. Palpi white, with a brownish suffusion on 

 outside. Occiput with conspicuous yellowish brown tuft of hair. Median stripe of thorax vestigial; inner 

 margins of patagia yellow. Abdomen black, with 3 golden yellow belts which are bordered posteriorly with 

 glossy white and situated on segments 2, 4 and 6. Anal tuft black, yellow above in the centre. On the under- 

 side segment 1 whitish, the hind margin distinctly yellow on segment 4 a'nd slightly yellow on the last 

 two segments. Anterior coxa glossy white. Legs black; fore tibia streaked with yellow, mid and hind tibiae 

 ■ with whitish rings at the base and apex; tarsi dusted with yellowish scales. The species is further characterised 

 by the costal edge being yellow in the last third in front of the outer vitreous patch. — Sicily (Miliuni, Fi- 

 cuzza, in June). 



Ch. haberhaueri Stgr. (51 k). Larger than alysoniformis and as in tiiat species without yellow shoulder- haherhaueri. 

 spot on the patagia. Forewing with 3 vitreous patches, of which the longitudinal one is short, in ^ some- 

 times vestigial only; the wedge-spot larger than in alysoniformis. Outer area black, only in exceptional cases 

 with a few yellow scales close to the margin; also the median band and the costal and hind margins without 

 light scaling, only the costal margin bearing a light-coloured edge towards apex. The cross-vein of the hind- 

 wing rather strongly scaled. Antenna of cJ very slightly notched, with very short cilia, blue-black, only 

 the outside yellowish towards apex. Hind margin of head broadly orange, palpi white, onty slightly black- 

 ish outwardly at the apex. Thorax with 5 yellow stripes, metanotum with yellow tufts of hair. The 

 abdomen black, with the hind margins of segments 2, 4 and 6 yellowish white, in $ often these segments en- 

 tirely yellow ; small yellow dorsal spots are present, but usually indistinct . Anal brush of (^ with thui whitish stripes 

 in the middle, the median lobe laterally with yellowish stripes on underside. In the $ with 2 broader, diver- 

 gent, more lateral yellowish smears, entirely dark on underside. The venter black, with segment 2 entirely 

 whitish yellow and segments 4 — 6 bearing yellowish lateral spots. Fore coxa snowy white. Tibiae white and 

 black; femora and tarsi dark. ■ — Taurus. 



Ch. alysoniformis H.-Schdff. (51 k). Distinguished particularly by its small size (expanse 13 — 18 mm), alysonifor- 

 the very small vitreous spots, of which the longitudinal one is absent in both sexes and the wedge-spot very ""«• 

 short. Outer vitreous patch rounded, tripartite, the first spot bemg sometimes covered with scalmg. Costal 

 margin not pale-edged before the apex; outer area dark, with 2 — 4 small yellow spots in the cellules. The cross- 

 vein of the hindwing widened anteriorly, pointed behind. Scalmg on outer surface of antennae ochreous. Palpi 

 yellow, whitish at the base, with brown apical segment. Hind margin of head red-yellow. Thorax with 3 

 yellow stripes, of which the median one reaches only to the centre. Abdomen black, with a steel-blue gloss, 

 Mdthout a dorsal line of pale spots, the hind borders of segments 2, 4 and 6 narrowly pale yellow, the borders 

 widening laterally and the first two being continuous beneath, segment 5 with a yellowish lateral spot. Anal brush 

 black, in ^ on each side with a thin yellow or white longitudinae streak, which is only indicated in $. Fore 

 coxa whitish; tibiae and tarsi steel-blue, the tibiae only in $ thinly yellow on outside and with some yellowish 

 hairs in the middle and at the apex. Easily distinguished from haberhaueri by the absence of the longitu- 

 dinal hyaline spot, the very small size of the other vitreous spots, the costal margm not being pale-edged before 

 the apex, the yellow streaks in the dark outer area, the yellow abdominal belt of segment 4 being complete 

 on underside, the absence of a dorsal line of spots, and the dark anal brush not being yellow m the middle; 

 differs from staudingeri in the absence of the light shoulder-spot on the patagia. — Bavarian Palatinate (Speyer), 

 Hungary, Dalmatia. East Roumelia, Greece, Western Asia Minor (Brussa) and Pontus. 



Ch. empiformis Esp. (51g, h). Exceedingly variable in size; the commonest species of the genus, empiformis. 

 Forewing blue-black, dusted with yellow, with yellow streaks in the distal area. Palpi predominantly yellow. 

 Occiput orange. Antennae black, suffused with yellow on outside. Thorax with a thm yellow median stripe 

 and broad yellow inner borders to the patagia. Frons without white borders to the eyes. No shoulder-spot 

 on the patagia. Segments 2, 4 and 6 above with yellow belts, behind which the hind edges are narrowly glossy 

 white; the other segments above more or less irrorated with yellow; dorsal line of yellow spots indistinct. 

 The ventral surface almost entirely dusted with yellow. Anal tuft very variable in colouring, being either 

 black with yellow stripes, or sometimes predominantly yellowish orange. Legs yellow, the tibiae with black 

 basal and apical rings; tarsi with blackish dusting. Cross- vein of hindwing tapering to a fme point behind. 

 — A larger and darker form, from Transcaucasia and Morea, is schizoceriformis KoL, in which the line of dorsal scMzoeeri- 

 spots is more distinct in the ^, the vitreous spots are smaller, often covered with yellow scaling, particularly formts. 

 m the $, and the hind tibia is more orange than yellow. — Likewise darker, especially in $, is hungarica To- lumgarica. 

 mala (51 h); it is more greenish black, with the wing-margms slightly dusted with yellow, usually less distinct
