CHAMAESPHECIA. By M. Bartel. 



pointed blackish end-segment. Head black with white bands before the eyes, edged with white below and 

 laterally and yellowish posteriorly. Frons brass-colour, variegated with white to a great extent. Vertex 

 black. Antennae black above, yellowish below; in the ^ clothed with very short fasciculated cilia, slightly 

 serrate' in the $ neither serrate nor ciliate, at most with a few hair-scales. Thorax smoky brown, with narrow 

 light median stripe, which is however usually absent. Patagia %vith ia distinct whitish inner edge, and very 

 broad white stripes on the outside (at the breast). White tufts of hdir around the metanotum. Breast brownish 

 black with white spots. Fore coxa white with a black inner edge. Fore and middle femora blackish, white 

 below; hind femur white for the greater part. Fore tibia dark, white beneath; middle and hind tibiae white, 

 with dark spots before the apex, hind tibiae with black stripes on the inside. Tarsi smoke-brown more or less 

 dusted with a light colour. Abdomen very like that of bibioniformis Esp. (with which the species cannot, ho- 

 wever, be compared on account of the white abdominal belts not joining below); it is brown-black, and, as in 

 the afore-mentioned species, bears a very distinct dorsal line of spots, which only becomes indistinct in worn 

 specimens, and shai-p white hmd edges to segments 2, 4 and 6. By this dorsal luie of white spots the species 

 is easily distinguished from affinis Stgr. Anal tuft of ^ very slender, consistuig of two long lateral lobes and 

 a short median tuft, but the farmer usually lie close together and are very closely compressed laterally; it 

 is narrowly striped with white laterally at the base (in the upper half); median tuft to a great extent varie- 

 gated with white, more rarel}' almost entirely white. Anal tuft of $ short, almost entirely dark, on the under- 

 side scarcely variegated with whitish. In a large $ in the possession of Herr Pungeler the anal tuft is distinguish- 

 ed by having a more or less distinct longitudinal stripe laterally above and below, and also is yellow below 

 at the apex. The venter is usually dark, only rarely there are traces of small light median spots. The lateral 

 edge of the abdomen is more or less distinctly striated with whitish; a prolongation upward of the central belt 

 is always especially distinct. — The species is rather variable, besides size particularly in the purity and extent 

 of the white colour. Ch. mysiniformis can only be compared v,-i\.h affinis St^r.; it is distinguished from it by 

 the shorter longitudinal patch of the (J, the smaller outer vitreous area, the more whitish and always lighter 

 colour of the cells of the outer area, by the antennae beuag yellow beneath, but especially by the sharp whitish 

 dorsal line of spots, and the anal tuft of the ^ being usually strongly compressed laterally, etc. Andalusia, 

 Granada (on the inflorescences of Euphorbiaceae, etc.), Malaga, Sierra Nevada, Lanjaron, Castile (Cuenca), 

 Algeria (Lambessa), the end of June and in July. 



affinis. Ch. affifiis Stgr. (51 k). Very variable in size. Distinguished from the alUed species by the segments 



of the antennae having no spiniform processes in the ^ and being unicolorous without spots in the $. Back 

 only with two yellow stripes at the inner edges of the patagia, without median streak. Abdomen not dusted 

 with yellow, m $ segments 4 and 6 and in the (J also 7 and partly 2 with narrow white posterior edges. ^J with 

 distinct yellow dorsal line of spots, $ without it. Anal tuft dark, in the (J Avith whitish hairs in the centre and 

 laterally, which are however sometimes absent; in the $ variegated with white only above, especially la- 

 terally. Fore coxa white, black on the inner side. Tibiae white in the middle and at the end, on the outer 

 side entirely clothed with white hair for two-thirds of their length. The outer vitreous area always broader 

 than it is high, not rounded, as in Corsica, consisting of three small spots. ■ — -In theRheingau, South Germany, 

 Alsatia, Switzerland, South Tyrol, Lower Austria, Hungary, Dalmatia, Piedmont, Southern France, Spain, 

 Corfu, Greece (Morea), Roumania, Turkey, Transcaucasia and Northern Asia Mmor. The larva lives in the 

 stalk and root of Helianthemum vulgare, on which the moth may also be found on sunny slopes from May 

 to the end of June. 



albivenius. Ch. albiventus Led. (52 c). Antennae black, in ^ strongly dentate and with spiniform processes. 



Frons with a metallic' gloss, with few yellow scales below. Abdomen of ^ very slender and compressed laterally, 

 quite snow-white below. Segment 4 with a broad white hind margin, segment 6 with a narrow one. A yellowish 

 dorsal line of spots. Cross-vem of hindwing as narrow as a hair posteriorly. Back with three pale yellow stripes. 

 The outer vitreous area traversed by three veins, about one-third as broad again as it is high. The two inner 

 vitreous areas present. Palpi snow-white with black end-segment. Anal tuft long and thin, black, with narrow 

 yellow lateral stripe. Fore coxa white ; tibiae white, black at the base and at the apex. — From North Western 

 Asia Minor (Brussa) and Mesopotamia; according to Baker also m Mauretania (aerifrons '^.). 



aerifrons. Ch. aerifrons Z. (51 k). Frons with a metallic gloss, without white bands to the eyes. Palpi pure 



white below. Thorax with yellow inner edges to the patagia. Antennae blackish blue, in the cJ without spmi- 

 form processes. Abdomen with a white posterior edge on segments 4 and 6 (in the J also 7). Anal tuft black, in the 

 (J whitish above and below in the centre. Fore coxa aeneous or whitish, mid and hind tibiae aeneous, with- 

 out hair. Outer vitreous area rounded, consisting of three pots above or below it usually one or two small 

 vestigial transparent spots. Cross-vem of hindwing entirely scaled, somewhat stouter anteriorly. — In the form 

 sardoa. sardoa Stgr. the antennae are golden yellow on the outer side, and on segment 2 there is an additional white 

 posterior edge. Fore coxa below entu'ely aeneous. — From ? Dalmatia, Hungary, Sardmia, Central Italj , 

 Sicily, Southern France, Spam, Algeria, Tunis and Syria, during the last ten days of May and throughout 

 June.
