402 OHAMAESPHKCIA. By M. Bartel. 



Verbasc-um ; pupation in tlii' ground; emergence from the middle of May to the middle of July. 



allanlijor- Ch. allatitiformis Ev. (51 g). Very close to masariformis and perhaps only a local form of it. The me- 



'"^^ dian band of the forewing essentially narrower, the longitudinal patch longer, particularly in the $; the outer 

 hvaline patch moreover larger in both sexes and its first spot and last one not filled in with yellow. Outer 

 marginal area very narrow m (J, broader in $, always with a row of yellow streaks. Palpi white, suffused 

 with yellow on the outside. Veins of the hindwing with yellow scaling. Abdomen with additional yellow 

 belt on segment 3 (a trace of a belt also on 5); on underside segment 2 entirely white, the last 3 (in 

 (J 4) segments also white, bearuag at most some orange scales posteriorly; segment 3 always with a white spot 

 beneath (in masariformis always dark). Anal brush of $ not black above at the sides. Tibiae orange, the 

 subapical black ring not so broad as m masariformis; fore coxa silvery white, with blackish margin in J. — 

 In the steppes of the Volga and Ural districts, the North-Western Caucasus, Transcaucasia, and the neighbor- 

 ing districts of Asia; from the end of May until July, flies frequently about the flowers of Achillea. 



loewH. Ch. loewii Zell. (51 g). Nearest to masariformis; the colouring of the light parts never orange, but 



golden yellow, the antennae yellow on the outside throughout their length, in (J serrate, with longer cilia. On 

 the dark bro\\ai forewing the longitudinal patch is vestigial in the ^ and absent in the $; outer hyaluie patch 

 smaller, composed of 3 — 5 small spots edged with yellow, as is also the wedge-spot; marginal area very 

 dark, broader in $ than in ^, with small yellow streaks, which are sometimes missing in the $; some- 

 times the outer vitreous patch is almost extended to the outer margin in the i^. Palpi yellow, whitish at the 

 base, in ^ the middle segment with black hair on the outside and the end-segment with black tip. Of the 

 yellow belts of the abdomen the one on segment 4 is the broadest ; segments 2 and 3 in c? and 3 in $ have 

 often slight yellow stripes above; segment 2 beneath almost entirely yellow, 4 — 7 in ^ with j^ellow belts 

 (sometimes entirely yellow); in ? the last 3 segments with yellow belts beneath, of which the one on segment 4 

 is the broadest. Anal tuft black in 9. above in the centre with 2 yellow longitudinal streaks; m ^ yellow, 

 with 2 broad black lateral tufts. Fore coxa white, mixed with black in (J. Tibiae yellow, with black subapical 

 ring on the mid and hind tibiae; these rings sometimes almost disappear entirely. Tarsi yellow, dusted witli 

 dark scaling. Very small specimens of this species without other distmctions have been separated as ab. loewii 



viinor. minor Stgr. — From Syria, the Taurus, Asia Mutor, and Southern Transcaucasia (Kasikoparan); from May 

 until Jidy. 

 moreaui. Ch, inoreaui le Cerf. Of the same size as loewii, but more robust and the wings more rounded. Head 



black, frons white anteriorly, vertex with fine whitish bristles. Palpi yellowish white, with a black exterior line. 

 Antennae long, very thin, with very short cilia, black on inside, outwardly whitish at the apex. Thorax black, with 

 a large yellowish white shoulder-spot and on each side a large spot variegated with Avhitish hair. Patagia and 

 metathorax entirely covered with white -yellow hair. Abdomen black, segment 2 beneath and half of it above 

 pale yellow, segments 3 and 5 with some small pale yellow scales, 4, 6 and 7 above entirely light yellow ; 

 on 4 and 7 the yellow colour deci'eases dowai wards, but reaches the ventral side. Anal brush very short, com- 

 posed of 2 central pale yellow tufts and 2 small yellow lateral ones. Coxae and femora bronze-black, margmed 

 with pure yellow, the femora black at the base ; tibiae yellow, base and a ring black ; tarsi pure yellow. Forewing 

 bronze-green, strongly variegated with yellow scales, the 3 hyahne patches well-developed, particularly 

 the outer one, which is composed of 5 spots and extends to the outer margin, the distal border therefore 

 very narrow. Hindwing hyaline, veins and a narrow border coloured as on forewing. Fringes of both 

 wings grey, interrupted with yellowish at the base of the hindwing; on underside small yellowish scales cover 

 the discocellular bar and hind margin. Expanse 23 mm. — Amasia. Differs from loewii in the larger size of 

 the vitreous patches, the reduced anal tuft, the thin antennae and the pale tone of the yellow colouring. 



pechi. Ch. pechi Stgr. (51 g). Nearest to loewii, distinguished by the longer cilia of the (^'-antenna. The fore- 



wing has a rounded outer vitreous patch which consists of 3 spots in $ and of 5 in c? ; outer area rather 

 broad, with 4 — 6 small obsolescent yellowish streaks. Vertex and frons black in ^ slightly variegated with 

 yellow, yellow in $. Palpi also yellow, with black hair on the outside. Antennae suffused with yellow on 

 outside, otherwise black above, m (J slightly serrate, with rather long cilia. Abdomen of $ with yellow belts 

 above and beneath on segments 2, 4, 5 and 6, the belts broadest on segments 4 and 2, narrowest on 5. In 

 (J complete belts usually only on segments 4 and 7, the belts much narrower and more indistinct on the 

 other segments, on underside segments 2 and 4 — 7 entirely yellow. Anal brush in ^ centrally yellow, beneath 

 orange, with the sides black; in $ black, at most mixed with yellow at the extreme tip. Fore coxa blackish, 

 whitish on outside; tibiae and tarsi yellow, the former with a subapical black ring, tarsi with blackish suffu- 

 sion. — From Algeria in June (Sebdou, Oran; Lambessa). 

 ■proximata. Ch. proximata (S^^grr. (52 b). Forewing of J with a very large outer vitreous patch leaving only a very 



narrow distal border, which is not dusted with yellow; in the $ the outer border broad and like the median 

 band without yellowish dusting. On underside the outer border likewise without yellow spots. Antennae 

 almost entirely yellowish broM'n, only the apex being black ; the Q-antenna somewhat thicker, more serrate 

 and with longer cilia than in masariformis. The yellow colouring of all the other parts of the uisect pale lemon- 

 yellow, nearly as in loewii. Palpi, legs and abdomen nearly as in loeivii and masariformis; the yellow belts on seg- 

 ments 4 and (5 of abdomen broadest, the belt on segment 2 distiiict, those on the other segments much
