perdita. liot'miiseuiii at X'ienna: tVoiii Persia. — In perdita >V'//.. t'nua Hr- (laueasiis, tlie ceiitial spots arc white, 



scovitzii. not being oi' scarcely centred witli red, and the liindwing is bruadly edf^ed with bhick. — scovitzii iU'n. 



(= sogdiana Ersch.) (7e) has a broad rosy red loliar and soiaetimes a red abdominal belt, on tiie liindwing 



a small, black, usually triangular spot being attached to the middle of the narrow black distal margin; 



separata. Persia and the Pamir. — In ab. separata >V'/c. (7e) the distal spots are narrowly but distinctly separated 



ersclio/fi. from one another; Southern Fergana. — erschoffi Sfyr. (7t) has spots .") and B often widely separate. 



standing side by side rather than one below the other; collar and 1-2 abdominal segments red, sometimes 



kavrigini. also tlie shoulders, as in our last ligure: Pamir. — kavrigini (ir.-fJrsh. (7fg) has the abdomen mostly 



kohistana. entirely red, inclusive of base; from Kuchara. — In the likewise Central Asiatic kohistana Gr.-Gr.-<li. on 



rosinae. ihe contrary there are only vestiges of a red collar and abdominal belt. — rosinae Korb (7f), from 



Armenia, resembles scorit^il. but the ])alpi and nearly the whole abdomen, especially in ?. are bright red. — 



glasiinovi. Here may also belong glasunovi, desciibeil by Grum-Grshimailo from a single sjjecimen which has remained 



beyond my reach. The individual is described as being black, without abdominal belt; a basal spot, 



2 central ones and 2 distal ones on forewing. the last being large, transverse and curved, purple like the 



narrowly black-margined liindwing; Dchidchigrut-Darja. — The prettiest and most variegated form, in short 



truchmena. one of the finest Burnets, is truchmena Ercrsm. (7g). It has a broad rosj- red collar, and the abdomen is 



bright I'ed, except the ajiex : the median pair of spots of forewing, however, is white and the basal half of 



olivieri. \iind\vmg transparent: Turkestan. — In olivieri Bohd. (= dsidsilia Frr.) (7h) not only the collar and 



2 — 8 abdominal segments are red but also the jjatagia, the red spots of the forewing being very large; 



from Syria and Armenia. — A further series of forms has a red abdomen, like truchmena; here belongs 



laelifica. laetifjca Jl.-Sch. (7g) with the pairs of spots on forewing separate, and hebe (Siifr. i. 1.) (7h) in which they 



hebe. j^,.g slightly connected with each other by whitish bars; from Hadjin. — In ganymedes ff.-ScIi. (7h), from 



^ '■^ ' Ainasia, the penultimate pair of spots and the apical patch are rather bruadly connected and the red 



markings of the forewing have a white edge of about 1 mm width. — The colour of the wings of the much 



formosa. smaller formosa If.-Sch. (7i), from Asia Minoi' and Syria, is far lighter ipale rosyi, the abdomen, however, 



malatiana. being black except a narrow belt. — In malatiana (.•>'<(/'■. i. 1.) (7hj this belt is broader, comprising the 



2—3 penultimate segments; Malatia, east of the Antitaurus. 



Very little is known of the habits of all these species and forms, which occur partly in districts 

 difficult of access. The early stages are mostl\' unknown, though the motiis occur like other Zygaenae in 

 large numbers at their flight-places. Esjteciaily of truchmena are we assured by H.\^hekh.\uer that it inhabits 

 the steppe of Turkestan in enormous numl)ers, occurring even in the gardens of the towns of that country. 

 The larva of xcoritzii is known, but not the food-]ilant; it is yellow-grey, with broad light dorsal stripe; 

 laterally there are rows of large black spots, Ijelow which there are light dots. 



escalerai. Z. escalerai i'ouj. has orange spots on forewing, the external i)airs being confluent; spot 6 is 



elongate and transverse. Tiie liindwing is orange, with a vermilion tint, the disc being hyaline and the 

 apex black, there Ueing a black dot situided at centre of distal margin. The species has been discovered 

 by EscALERA in Persia, the type contained in the Paris Museum being caught in .luly. According to the 

 description this form is allied to the fa.iini-fn(climeiia-gvou\}. 



Iiilan's. Z. hilaris (>. (7i). .\s small as or even smaller than formosa. The red colour i)redominates so 



mucli tliat it occupies the whole foi-ewing, there remaining only small black sjiots. which are sometimes 



contiuent, but are often reduced to dots standing widely separate. The red collar of the preceding and 



following grouj) is never present; however, sometimes there are yellowish white hairs at the edge of the 



thorax. Common at the Riviera and the South-East Coast of Spain. From Digne, in the Basses Aljjes. I 



have before me a pale yellow aberration belonging to the Tring Museum: the figure (7ii bears the name 



pallida, however I do not consider it necessarv to give here names to such pale yellow aberrations, if they 



ononidis. have not already received names. — In ononidis Mill., from the French Riviera, the red spots are not 



cscorialensis. separated by yellowish white borders from tiie black ground. — In escorialensis Ohrrtli. (7k), from the 



Castilian table-land, the wings are more thinly scaled, pale rosy, the black s|)ots are reduced to thinly pale- 



felix. edged dots. — In fellx Oberth. (7 k), from Algiers and South -West S])ain, the black spots are more or less 



contiuent, the red ground-colour along the distal margin being sometimes separated as a sock-like halfmoon. 



faustula. The white edges are usually altogether absent, or there are only feeble vestiges of them. — In ab. faustula 



Stgr.-Reb. (8 a) on the contrary the black spots are distinctly edged Avith yellowish white. — Lastly, ab. 



maiiretanka. maurctanica Styr. (8a) has a red belt. — The 3 last forms tly exactly at the same time and the same 



places; i found them frequently united in copula. They are extremely common throughout June on 



nearly all the heights of the Atlas Mts., sometimes the one sometimes the other form being prevalent in 



confluens. the various flight-places. — As rare exceptional forms we have further to mention ab. confluens Oberth. 



(7i) in which there are only very small black light-edged dots on the otherwise entirely red forewing; ab- 



hkolor. bicolor Oberth. (7k) which has no black but only light dots (remnants of the edging), and lastly ab. 



unicolor. unicolor Oberth. (7k) in which the A\ings are uniformly red, being narrowly bordered with black. These 



last 3 forms have been found in the Pyrenees among the normal form. — Larva very short and thick,
