 \vin<r very ]>ale violaceous ijrev, yellowisli at l)ase, and traversed in its middle from eosta to inner mar<>;in l)vau 

 irreiiular darker shade; the outer edj^e of the basal third is very irregular and proehiced in a sharp an<;le at the 

 innermost median nervule, and is narrowly shaded where it joins the median space by darker tint ; the inner 

 half of the median space is tinted with brownish, the outer hali' is same pale violaceous <irey as the basal part ; 

 the outer edu-e of the lucdian s])ace is scallo|)ed and shaded with darker jTrey ; a lar^e pale discal mark ; the 

 third or terminal space is of the same pale jirey as the major part of rest of winir, shaded on costal half with 

 pale yellowish fawn, a darker patch on inner mari;iu not far from inner anjile. Secondaries dull crimson, vel- 

 lowish white at inner margin, and a large |)aie grey |>atch covers that ])art of the wing at and near the anal 

 angle, within which patch is a blackish (hish parallel with outer margin, betw'een which latter and said dash is 

 a faint grey abbreviated line extentling froiu the anal angle inwards to where the crimson colour commences. 

 I'nder surface of all wings very pale yellowish f"awn with a l)road terminal I)and but a shade darker ; basal half 

 of priiuaries dull crimson, which colour does not however extend to either eosta or inner margin, and the diseal 

 mark is designated by the pale lawn oi' ground colour of wing.

'I'his diifers from its nearest ally, Modeda, Harr., in the far greater breadth of wing, tlic great robustness 

 of body, the entirely different colour and in the difference of the undulations of the transverse lines and shades, 

 also in the shape and greater size of the discal mark or bar. In ModeMa and its Pacific coast var. (Jinidtnldlis, 

 Ily. Edwds , the colours are even, smooth shades, well defmed and separated from each other by demarkatiou 

 lines, whilst in Imperator the colours are blended more or les< into each other and have a heavy jiowderv ap- 

 IH'arance, the scales being far heavier and rougher as seen through a lens than in Harris' s])eeies. Ivijterator 

 approaches the var. Occideiitalis somewhat, and somewhat only, in the i^ileness of the ground colour, but be- 

 yond this there is no nearer ap|)roach than to the stem form typical Modesta, to which Occidentalis a.ssimilates 

 in every respect except being jialer in coloui' and generally of larger size. 



Kor lliis species, wliicli I coiisider one (it' the {;r;uiilist ;ui|nisiliiiiis iiiir Ileteruoeroiis fauna lias for a Idiif; time received, as well 

 as for a large nunilier ol oilier rare and new species from inner Arizona ami Utah, I am indebted lo llie energy and perseverance of 

 Mr. li. Neumiiegen of New York. Heretofore, owing to its lieing mainly in possession of the Indians, as well as to its unfavorable 

 climate and general sterility, tlie re|iresentation of tlie Lep. faniia of .\ri/.ona was of the most nieagri' description imaginalile. comprised 

 in a few c.\amples in llie coll. of \V. 11. lOdwds., and fewer still in the Miis. of the Agricultural Deji. at Wasliingtoii, all derived from 

 the same .source, the chance collections of government exploring and surveying parties. For years Arifi/nnis Nokomis was known only 

 liy a single tattered rf , and later for a hng time by a t'cw more, ,Y' 'itid 9 ■ When my friend Netmioegen commenceil a few years since 

 to study and collect Leiiidoptera, to which he applied hiin.self with an energy seldom equaled, I impre.-^sed on him the importance of 

 obtaining e.xamples from .\rizona. giving bini drawings and descriptions of jVo/omis and some other prominent species. By indefati- 

 gable industry he .secured coilectors who from inner .\rizona, in a remarkably short time, .*ent a large quantity of the most interesting 

 mati'rial, among which wi^re the almve described splendid ^vifrinlhua, as well as a number of others new to science, which will he de- 

 scribed in the present and future parts of this work. In the lirst lot received of these .Arizona Lep, were a nmnber of both sc.xes of the 

 coveted yokviiiis, but nnfurtiinatidy the season was so far advanced when the onslaught cotiiinenced that all were torn <u- too long flown 

 to be desirable; the glory of laier sendiugs made however ample amends fortius tirst quasi disappointnunt. .\ large [iroportion of 

 these insects seem to be remarkably pale aberrant forms or repre.sentations of Pacific or Eastern species; prominent in this respect are 

 Mel. Alma, n. s., Arg. Nokomis, W. H. ICdwils,, Pup. Ulalintsis, n. s. or v., Sph. KIsa, n. s., Pseud. Nullalli and others. An/. Nokomis 

 I have always considered as an extreme variety of A. Cybcle. as I believe the Anioor and North China A. Sayinia* may hea form of the 

 East Europe A. Lamlice; but to this subject I will revert in my description of the various new species from this wonderland. 



I cannot omit nicntiiming another still more astonishing t hie;;, it) connection with lhereceptionoftlie.se .Arizona novelties, which in- 

 credible as it may ajipear, is neverthele.ss a fact, to the triilii of which I am willing at any time lo be qualified with pnqier jurat 

 appended ; it i-- that when Mr. Xeunioegcn passed tlii'm to me for description he did not even hint, let alone make it the condition, that 

 any of the new species should be named after himself, his wife, his aunts or his consins-german, his grandparents, the stranger within 

 his gates, or even after his rich neighbor. May his sUuIclon be preserved I
