BUTTERFLIES OF MONTANA. IX Preface. In preparing some Nature Study work for teachers it became appar- ent that teachers have little to work on in this region to enable them to prepare studies on butterflies. It was really to assist teachers and others in identifying specimens that this bulletin was prepared. It is hoped that it will meet the needs of teachers and be of material assistance to them. The boys and girls of the state have little to assist them in the study of natural history specimens of the state, since the books which would be serviceable are either too expensice or too volumnious to handle. If the study of the butterflies is stimulated in the coming generation the writer will feel amply repaid. Full credit for most of the assistance rendered has been given in the Introduction. Mrs. C. A. Wiley, of Miles City, has very kindly placed at our disposal a copy of Edwards' Butterflies of North America, with colored plates. Supt. P. M. Silloway of, Lewistown, has rendered material aid in collecting specimens at Swan lake. The glossary has been prepared by Josiah J. Moore, of Anaconda, a student at the University of Montana. The index nas largely been prepared by my wife. I offer no apology for making some of the descriptions much longer than others. Some of these are totally inaccessible to hundreds of those who will use this work. A lengthy description of a species that will be difficult of determination will be of great service to the young student. Where the specific characters are easy of determination and good photo- graphs are supplied the descriptions are brief. After the matter was all in type a list of butterflies was received from Prof. Ezra Allen, of the State Normal at Dillon, which specimens have been incorporated in the work. The information in this bulletin includes reference to specimens collected in the eastern end of the state at Miles City, the central portion at Bozeman, the southern part at Aldridge and Dillon, the main Rocky Mountain region at Helena, the western slope at Missoula and Flathead Lake.

My first butterflies captured in the state were taken at Miles City in the east and Mount Lo Lo in the west during a recreation trip in August, 1892. In 1897 I came to the state to live. Every summer since then to the present time has been spent in the field, and the ac- cumulated insects have been arranged at the University of Montana, where they have been worked over at leisure moments. In the fall of 1900 Miss Frances Inez Maley was given the task of spreading, arranging and labeling the material, identifying it so far as possible with the specimens and literature at command. A large portion of her time for that school year was devoted to the work. The collection of more than a thousand specimens was spread and arranged in Corn- stock cases. A large number of the photographs were taken at that time, others later. Many of the keys and descriptions were prepared by her, and the results of her careful and painstaking labor were submitted to the faculty as her graduating thesis for the degree B. A. in June, 1901. As it was impossible then to correct and verify as must necessarily be done before printing, it was decided to test the keys and make further addition to the list by including references to all the collections avail- able in the state. For several summers the keys have been in the hands of many persons both at the University in regular work and at the Uni- versity of Montana Biological Station at Flathead lake. In this way many errors have been avoided, and the keys have been found to be serviceable in the hands of beginners. Moreover, by the examniation of other collec- tions many additions were made, necessitating changes in the keys and in the text. Many of the discriptions were rewritten. To avoid confusion it was decided to follow the nomenclature used by Dyar and others in Bulletin 52, United States National Museum. In this bulletin many species recorded in other publications are reduced to synonyms or varieties of other species. After examining so many hun- dreds of specimens from various parts of the state, at different altitudes, I feel convinced that the list can be reduced still further without detri- ment, and without sacrificing. To cite a single illustration. The Wiley collection has specimens of Argynnis from Miles City, collected in 1893, and identified by Edwards as A. edwardsi. Specimens from Miles City sent by myself to Edwards in 1892 were labeled A. nevadensis. When placed side by side they look exactly alike, and are undoubtedly of the same species. Owing to the varying conditions as to heat and cold, moisture and sunshine, which prevail in the state, many species are subject to great variation. This makes identification oftentimes difficult, and we have 4 BULLETIN UNIVERSITY OF MONTANA. often been greatly puzzled. As a result of these great variations, com- bined with the mistakes one is likely to make in undertaking a task like this so far from library centers and large collections, we feel that we have certainly made many errors, of which we are now not aware. We have at least brought together the material in the state and have brought it into some kind of order for students of butterflies later to make more perfect. The task has been all the more difficult because the state con- tains specimens from the Great Plains region, from the Pacific coast region, and from the Boreal fauna in the north. The collections examined and recorded in this bulletin are the follow- ing: (1) The collection made by the writer, almost entirely in the museum of the University of Montana, made during the past eight seasons of collecting. These have been taken mostly in the western end of the state. The numbers of specimens in the collection has not been deter- mined, but there are many thousand. (2) George E. Barnes, a graduate of the University, made a collection of several hundred in the vicinity of Aldridge, in the southern part of the state near the Park. These were generously donated by him to the University. (3) E. N. Brandegee, of Helena, made a collection of several hundred specimens in the vicinity of Helena in 1902. These he very kindly placed at the disposal of the writer for examination and study. (4) The late C. A. Wiley, of Miles City, made an extensive collection of Lepidoptera in eastern Montana during his sev- eral years of residence in Montana. This collection came to the Uni- versity entire, and has been gone over carefully. (5) The collection at the Montana College of Agriculture and Mechanic Arts at Bozeman, the work of Professor R. A. Cooley, was very kindly placed at my disposal by Prof. Cooley. This contains a good series of insects, excellently mounted, and in some cases from high altitudes. Eugene Coubeaux, of Big Sandy, made a collection during the summers of 1904 and 1J./05, and very kindly loaned specimens for examination. He also furtnisaed notes regarding the abundance of each species. These five collections practically represent the butterfly collections in the state. They contain specimens from the extreme east and west, and from the south. The great section of country tributary to the Missouri river in the northeast is not repre- sented, nor is the extreme north in the Rocky Mountains. Other authors have been referred to and quoted freely. The illustrations are almost entirely original. The colored plate is the result of the work of Mrs. Edith Ricker, of Burlington, Iowa, who has spent three summers at the Station at Flathead. Colored drawings were made from specimens and the colored drawings were made into the printed plate by the three color process. It is to be regretted that the expense precluded more generous use of colored plates, instead of the half tones. Many of the drawings were also made by Mrs. Ricker and her brother, Lisle W. Brown, now in connection with the Eastman Kodak Company, including all of the figures of wing venation, except a few made by Claude Spaulding, laboratory assistant at the University. The photo- graphs of butterflies were made by Miss Maley, Mr. Spaulding and the writer. Other photographs used have appropriate credit given with each. BUTTERFLIES OF MONTANA. 5 Without the generous aid of these friends, who gave their work cheerfully and gratuitously, these original illustrations would be lacking. We are deeply indebted to President Craig, of the University, for the cordial support he has given us in our efforts to popularize this subject and make the study available to the younger generation of the state. His liberal policy has enabled us to use copious illustrations, and any plan for better results or for increased usefulness of publications has always met with his hearty favor. • The pleasure we have found in the preparation of the material for publication has been ample compensation for the labor. We can wish for those who peruse it or read it no more enjoyment in its use than has been ours in gathering the specimens and bringing them together. Every specimen which we have gathered recalls some scene, whether it be the jagged sky line of the back bone of the continent as viewed from the Swan range when we were sweeping in a few Phyciodes, a battered Eurymus alexandra, or the various species of Argynnids, or the quiet and peaceful woods adjacent to the laboratory at Flathead lake. Again, as we pick up Satyrus olympus or Brenthis myrina we are reminded of the dusky faces on the Flathead reservation and the beautiful Mission valley, flanked by the majestic Mission mountains. Vanessa californica brings to us in winter the first breath of spring, as it is our earliest specimen, coming at Missoula in 1903, February 19. Vanessa J. album carries us to Swan lake, where the manical call of the loon is answered by the blood curdling shrief of the puma, while the water lap-laps the bottom of our boat as we head for the campfire on shore. Beautiful, dainty, golden laced Lycana melissa carries us to Sin- yaleamin lake, cradled in the mountains, where we spent such happy and care free days. Oeneas chryxus takes our memory to Mount Woody, south of Missoula, which we have ascended a dozen times for butterflies. Whichever way we turn, whatever insect we pick up, our memory brings to us days of happiness and pleasure. M. J. ELROD, University of Montana. BULLETIN UNIVERSITY OF MONTANA. Montana. Montana lies between the parallels of 49 degrees and 44 degrees 15 minutes north latitude, and extends from 104 degrees to 116 degrees west longitude. The form of the state is nearly a parallelogram, being about 540 miles in length with an average width of 275 miles. The surface of the state is generally mountainous. The main range of the Rocky mountains, with numerous spurs, traverses the western part in a direction northwest to southeast; between these are many beautiful and extensive valleys, which cover nearly three-fourths of its area. The northeastern fourth is a high, rolling prairie country, covered with nu- tritious grasses. A considerable portion of the country between the Mis- souri and Yellowstone rivers is occupied by the Mauvaises Terres. The average elevation of the surface is about 4,000 feet above the level of the sea. The elevation of the eastern third of the state is less than 3,000 feet, while that of the mountains and foothills in the western part of the state is from 4,000 to 10,000 feet. The highest peak is above 12,000 feet. The surface rises westward at the rate of about eight feet per mile. This state has extremes of climate. Many sections of the state ex- perience severe northern blizzards, others have delightful summers, still others hot deserts. Lovely lakes lie in the north, dry treeless plains In the east, almost devoid of vegetation. The western slopes with their copious rainfall afford a climate moist and warm. To the south are mountains capped with snow. Between these are many grand canyons. Bui. Univ. of Mont. Biol. Series No. 10. Plate II.

In collecting butterflies a net is necessary, and some means of killing them after capture. The simplest form of the net, which can be made almost anywhere, is constructed as follows: A rod of some light stiff material is used as the handle, not more than five feet in length. Attached to this at its upper end is a loop or ring made of metal or some moderately stiff yet flexible material. Upon this then should be sewed a bag of fine netting, preferably tarlatan, almost thirty inches deep; the ring should be not less than a foot in diameter. Several forms of folding nets are on the market by dealers in entomological supplies. These nets are detachable from the handle, and will fold in two or more pieces. They may thus be tucked in a pocket or packed in with bag- gage without injury, to be drawn out and speedily ad- justed when necessary. Handles may also be pur- chased which fit together in sections, and are likewise easily transported and quickly adjusted. See Fig. 1. Fig. i. A butterfly net. Nets may be purchased with silk bags if desired. A silk bag has many advantages. It dries readily when wet, requiring but a few swishes through the air. It may be swept through the air with much greater speed than any other net. It does not snag readily, and has a much longer life. The specimens collected are killed in some way that shall not muti- late them. A very convenient way is by means of the cyanide bottle, which is prepared in the following manner: Take a wide mouthed bottle holding four or six ounces. Put in the bottle a piece of cyanide of potassium about three-fourths of an inch square or a table spoonful of s BULLETIN UNIVERSITY OF MONTANA. the pulverized, and water enough to cover the cyanide and then, imme- diately before there is time for the cyanide to dissolve, put enough plaster of Paris in the bottle to soak up the water. Cut a paper as in Fig. 2 to cover the plaster. The bottle should then be left open in a shady place for an hour to dry and then securely corked and labeled "Poison." See Fig. 3. Specimens placed in the bottle to be killed should be left ther6 f°f &t leESt a h&lf hOUr> but theV may b6 left in over night without injury. Another method of killing the insect is to enclose a piece of cotton, upon which a few drops of chloroform, sulphuric ether or benzene has been put, with the insect to be killed, in a small bottle or small box. Still another method of killing is to entangle the insect in the meshes of the (silk) net, with wings over the back, and give a quick but hard squeeze on the sides of the thorax. This may do some injury to the insect by rubbing off some scales, but in the absence of a killing bottle it may be necessary to kill a specimen or lose it. Much of the success of the collector will depend upon his skill in the use of his net. No description of the method is worth anything besides a very little ex- perience, and one soon learns to capture with dextrous turn of the hand, "practice makes perfect." It is possible to sweep into the net an insect which is fluttering through the air and by a turn of the hand to close the bag. One manner which is preferred by many is to clap the net over the butterfly and allow it to rise, and then insert the bottle in the net and without touching it allow it to drop into the bottle. If possible the fingers should never be allowed to come in contact with the wings. Papering Specimens — When time and place do not suffice for the proper preparation of the butterflies, they may be placed in en- velopes, until such a time as one is able to relax and properly mount them. The small dry envelopes are very good for this. The insect while in the net usually has its wings folded back. It may also be dropped into a triangular envelope made by folding a Fig. 3. Cyanide bottle, piece of paper as shown in Fig. 4, and a memorandum of the locality and date of capture is written on the envelope. They may then be packed in a shallow box, a cigar box being preferable. When it is desired to pin and spread specimens that have been stored away they are relaxed. To do this take several large sheets of blotting paper, wet with water, place the papered butterflies on the sheets, then BUTTERFLIES OF MONTANA. 9 wet two more sheets and place over these. Do this as often as there are insects to be covered. Let them remain here two or three days, at the end of which time they can be spread as easily as when fresh. Care must be taken not to leave the specimens here too long lest they became mouldy. In spreading insects, the insect should first of all be pinned, the pin be- ing thrust perpendicularly through the thorax, leaving about one-fourth of the pin to view. It should then be placed upon the setting-board. Setting-boards are two pieces of board slanted toward the inside. Many collectors prefer straight boards, with a piece of cork be- neath, and a groove on the upper surface of sufficient depth to accommodate the body of the insect and to permit the wings to be brought to a level of the Fig. 4. Folded paper for insects. upper surface of the board. When the insect has been pinned upon the board the next step is to set the wings in the position which they are to maintain when the specimen is thoroughly dry. In bringing the wings into position, care should be taken to put the pin behind the strong nervure, on the costal margin of the wing; other- wise the wings are liable to be torn and disfigured. The rule is to draw the anterior wing forward in such a manner that the posterior margin of this wing is at right angle to the axis of the body, the axis being a line drawn through the head to the extremity of the abdomen. The hind wing should then be moved forward, its anterior margin lying under the pos- terior margin of the fore wing. When thus arranged slips of paper should be drawn over them and securely pinned to keep them in position, and the pins removed from the wings. Never pin through the wing. Next the antennae should be adjusted ,and placed parallel with the wings, and fine pins placed about them to hold them in position. Then if the body has a tendency to droop it should be raised by placing pins under it on either side. See Fig. 5. When insects have been spread the board should be placed where they will be unmolested and free from dust. They should be left here for about a week, longer if the insect is very large, at the end of which time they may be taken off and put in the cabinet. Labelling — Each specimen should have on the pin below the specimen a small label, giving the date of capture, if known, and the locality. Labels should be printed, or written in a fine hand, and preferably with India ink. 10 BULLETIN UNIVERSITY OF MONTANA. Fig. 5. Settling board, wing method of pii for the collection. ing and spreading insects Pins — The insect pins are made longer and thinner than ordinary pins. Pins, pinning forceps, Fig. 6, printed labels, insect boxes and cabinets, sheet cork or peat, or other entomological suppiles may be had of dealers in this material. A jappanned steel pin is now on the market which is much superior to any pins heretofore made in that smaller pins may be used and still have greater stiffness and strength. For cabinets such pins are much more desirable, but at the same time are more expensive than ordinary pins. Fig. 6. Pinning forceps, for pressing pi BUTTERFLIES OF MONTANA. 11 Venation of the Wings. The thickened lines in the wings are termed the veins or nerves; and their arrangement is described as the venation or neuration of the wings. The thin spaces of the wings which are bounded by the veins are called cells. When a cell is not completely surrounded by veins it is said to be open. The wings of different insects vary greatly in structure, but they are all more are less triangular in outline; they therefore have three margins; the costal margin or costa (a b) ; the outer margin b, c, and the inner margin c. a. The angle at the base of the costal margin and the outer margin is the apex of the wing; and the angle between the outer margin and the inner margin is the anal angle. The principal veins of the wings are, beginning with the one lying on the costal margin, the costa, the subcosta, the radius, the media, the cubitus, and the anal veins. The radius media, and cubitus are usually branched and there may be several anal veins. In some insects there are the premedia a vein- lying between the media and radia; and a postmedia lying between the media and the cubitus. I Costa V Media VIII) II Subcosta VI Postmedia IX) III Radius VII Cubitus X) Anal IV Premedia et al) By referring to Figs. 7-12 these veins may easily be studied. As many of the generic distinctions are based on the venation it is essential that the student become thoroughly familiar with the locations and numbering of veins of wings. 12 BULLETIN UNIVERSITY OP MONTANA.

The white ground is marked with smoky black to a greater or less ex- tent. On the wings are yellow or pink spots, varying in size, margined BUTTERFLIES OF MONTANA. 15 with black. There is a marked difference between the females and males, the latter being much whiter with the smoky black confined to the outer border of the wings and the inner edge of the hind wings. There is a black bar in the middle of the discal cell of fore wings, another at the outer end of the cell, beyond which is a more or less prominent bar with or without red spots (one or two). The female is much darker, with the whole upper surface of the primaries usually smoky-black hue, slightly transparent, the usual bands being lost in the ground color of the wing. Yellow or pink spots much larger than in the male. The variety hermodour is much blacker than smintheus. Both are found in the state. Comparison of specimens from Montana with those from Pike's Peak show the latter to be much smaller, and lighter. As Fig. 14, Parnassius smintheus, var. hermodour, female. the Pike's Peak specimens are from altitude 12,000 feet and Montana specimens from 3,000 to 7,000 this is to be expected. These butterflies are truly Alpine, and fly for but a short season of the year. The lowest altitude at which they have been taken is about 3,000 feet near the Biological Station at Flathead lake. At Missoula they are rare, and have not been taken below 5,000 feet, and then in small numbers. They fly lazily but easily. Owing to the fact that they are usually taken at high altitudes their capture results in much fatigue. Often they sail gracefully over a cliff when the pursuer is all but ready for a sweep of the net. In the same locality high eleavtion seems to result in smaller and blacker specimens, low elevation in larger and whiter ones. Distribution — The University collection contains specimnes from Missoula, Tobacco Root Mountains, Mission Mountains, New Chicago, Madison Lake, Geyser Basin, Flathead Lake, the Swan Range and the National Park. It is found at higher elevations throughout the state, ranging from Colorado to California, Montana to New Mexico. Its north- ern limit is unknown. According to Edwards it has been taken as far 1C BULLETIN UNIVERSITY OF MONTANA. as Loggan, Alberta. Coubeaux has collected it at Sheep Creek near Big Sandy. He says it is not common in the Highwood and Little Belt Mountains, and that it seems to be absent from the Bear Paw Mountains. Food — The caterpillar feeds on Sedum and Saxifraga. The butterfly is common in the mountains about Helena (Brandegee). Cooley has collected it at Bozeman. THE CLODIUS BUTTERFLY. Parnassius clodius Menetries, Fig. 15. Fig. 15, Parnassius clodius. Prof. R. A. Cooley, of the College of Agriculture and Mechanic Arts at Bozeman, has sent us two specimens, male and female, of this species, taken in Gallatin county, where he reports them rather abundant. The pink and yellow spots are lacking on the primaries in both sexes. The male has more smoky brown on the outer edge and base of primaries, with more translucent outer margin. The differences are more clearly shown by comparison of Figs. 13 to 15. Distribution — Clodius is found upon the mountains of California. It is reported from the state by Prof. Cooley as stated. Carrington and Logan collected it on the expedition in 1871. Food — The capterpillar feeds on Sedum and Saxifraga. BUTTERFLIES OF .MONTANA. 17 Collecting: Butterflies at High Altitudes. My first high altitude collecting was at 11,500 feet at Seven Lakes, Pike's Peak. It was in August, 1892. Ice formed at night, and all insect life was quiet. During the warm days butterflies were abundant. For the first time I saw Parnassius in all its splendor. But to capture it was difficult. Not being accustomed to the high altitude I was unable to make vigorous effort, and after a short chase would drop to the ground gasping for breath. Our camp was in the valley on the bank of one of the "Seven Lakes," in the home of Parnassius smintheus. They were out by the thousands. A few miles from camp, toward the main summit, an irriga- tion or water ditch had the surface of the water covered as far as we could see in either direction with dead or struggling larvae of smintheus. Above timber line and up to the line of perpetual snow there is in summer a profuse growth of Alpine flowers. One who has not seen high altitude vegetation cannot comprehend the beauty, splendor, and pro- fusion of high altitude or alpine flowers. They are a sight never to be forgotten. Above timber line there is in summer a profuse growth. On sheltered or sunny slopes there is a varied vegetation, the flowers making a beautiful sight. One of these visions is the most gorgeous I have ever seen or ever hope to see. I was caught in a shower of rain, hail, sleet, and snow, and had hastened to a large rock. By clinging with both hands and feet I was somewhat protected. After an hour the storm passed, and the sun came out bright and warm. Sunshine always brings out insects, if they are about. The storm left a deposit of snow an inch or two in depth over the surface of the mountain for miles around. Above the snow, showing their varied colors, were thousands of flowers of different tints, from the genera Actinella, Allium, Mertensia, Silene, Castilleia, Polygonum, Geum, Sedum, and Potentilla. Hovering over these flowers were hundreds of butterflies, displaying their gorgeous colors. It was a rare sight, and a rare combination of snow, alpine flowers and alpine butterflies. The in- sects were Parnassius smintheus, Colias ochraeus, Colias meadii, Argyn- nis eurynome, Phyciodes nycteis, Argynnis helena, and Lycaena rustica. Such a blending and contrast of colors is rarely seen, and forgetting everything I stood for a long time drinking it in. This view is indelibly stamped on my memory. It cannot be forgotten. Soon the mournful squeak of the pika on the rocks nearby called my attention, as it was the pika I was after. In a short time the snow had disappeared, and the six mile walk to camp was cheerfully made. It has not been my good fortune to climb high mountains. I have done no collecting above 14,000 feet. Among the Rockies of Montana my work has been at altitudes below 10,000 feet. My next attempt at ]g BULLETIN UNIVERSITY OF MONTANA. collecting at altitudes higher than common was in the National Park, at an altitude of 8,500 feet. Again I saw Parnassius smintheus, that gor- geous insect of the alpine realm. I gave chase, and after landing the prize in the net sank to the ground exhausted and gasping for breath. In the Mission Mountains of Montana I have had many a happy day among the peaks at 9,500 feet and lower. This short range has some of the most beautiful mountain scenery in the world. Many of the insects taken are recorded in this work. I have collected in the Swan range, and in the main range of the Rockies, at altitudes up to 10,000 feet. In northern Montana timber line is 9,500 feet. In Colorado it is about 11,500 or 12,000 feet. These two elevations in the different localities will probably have about the same flora and fauna, or at least similar condi- tions. Never have I found insects so abundant as at Seven Lakes on Pike's Peak, and rarely are they abundant. Quite frequently but a single specimen is captured, often but a few. For several years we have an- nually made the ascent of MacDougal Peak in the Swan Range, whose elevation is approximately 7,600 feet. On these occasions I stay behind to see that all are going down safely. I always loiter on the summit or along the long ridge, collecting a few Lycaenas, Argynnids, Pierids, or Phyciodes. ? If the butterfly students of Montana will seek healthful exercise, magnificent view of snow-clad mountain summits and peaceful wooded valleys, with a catch of few but rare and very choice insects, let them ascend some high peak in July or August, seek a sunny slope of open woods and abundant vegetation, and pitch their tents for a week. It will add years to the latter end of life. M. J. E. Bui. Univ. of Mont., Biol. Series No. 10. Plate III.

Large species, hind wings tailed. Ground color of the wings black, usually marked with yellow, and often with metallic blue or green, or yellow marked with black. Papilio. Genus PAPILIO, Linnaeus. Butterfly — There is great diversity of form in the wings of this genus. They are large butterflies, often known as swallow tails. The wings are ample; the fore wings triangular; the hind wings concave next to the body, and usually provided with a tail-like appendage before the anal angle; outer margin dentate. See Fig. 16. Early Stages — The eggs are somewhat glob- ular, flattened at the base, and smooth. The caterpillars are cylindrical, fleshy, thicker in the anterior portion of the body. There aje about twenty-seven species of this genus found within the limits of boreal America. KEY TO SPECIES OF PAPILIO. 1. Ground color yellow, with black bands. 2.

THE DAUNUS BUTTERFLY OR SWALLOWTAIL. Papilio daunus, Boisduval, Fig. 17. Fig. 17, Papilio daunus. butterfly — Expanse 4.00-5.25 inches. Upper surface of wings clear yellow, costa and outer border of fore wings and posterior border of hind wings black. The black along the costa is suffused with yellow, eight spots in the fore and four lunules in the hind wings. The lunule on the hind wings is orange color. There are four black bands on the fore wings. The first is continued two-thirds across the hind wings and is about one-fourth the distance from the base to the outer margin. The second extends from the costa to a little beyond the median vein; the third extends from the costa across the discal cell; the fourth from the costal to the fifth sub-costal venule. The black terminal border of the hind wings contains blue clouds. It has two tails which are black, edged on the inside with yellow. The under side is similar to the upper. The body is black with yellow stripes on each side. It is the largest of our butterflies, very conspicuous when on the wing, and eagerly sought by the young entomologist. It is apparently absent from the treeless eastern end of the state. Food — The early stages have not been thoroughly studied, but it is BUTTERFLIES OF MONTANA. 21 allied to the other members of the family. The caterpillar feeds on a great variety of plants. Distribution — It is found among the eastern valleys of the Rocky Mountains and descends into Mexico. In Arizona it is quite common. In Montana it is on the wing by the last of April. It is very similar to the turn us of the eastern and middle states, but is larger, and with two tails to the wings. It is rather common in the western end of the state, but nowhere abundant. Wiley does not report it from the eastern end, ex- cept to refer a specimen on the wing to either daunus or rutulus. Brande- gee has taken it at Helena. THE TURNUS SWALLOW-TAIL. Papilio turnus, Linnaeus. Butterfly — Expanse of male, 3.00 to 4.00 inches, 75 to 100 mm.; female, 3.50 to 5.00 inches, 87 to 125 mm. Ihis species very closely resembles rutulus, or, rather, rutulus very closely resembles turnus. It may be distinguished by the fact that the marginal spots on the under side of the fore wings are separate, while in rutulus they join together. The species is dimorphic in the female sex in the southern portion of the territory it occupies. At first the black form was regarded as a distinct species, but it is now known that the black and yellow females are of the same species. By experiments it is shown that eggs from yellow females produce black females, and conversely eggs from black females produce yellow females. The dark or black female does not occur in Canada or in the country northward and westward. Holland has obtained speci- mens of a small dwarfed yellow form near Sitka. Early Stages — The egg is green or bluish green, with occasionally some reddish spots. The caterpillar feeds on the wild cherry and other plants. Distribution — It abounds in the wooded regions in the eastern United States, often in great numbers, extending from New England to the Gulf of Mexico. Westward it is found to the Rocky Mountains, extending northward to Alaska. In the state it has been taken by Carrington and Logan in 1871, locality not given. Several specimens of turnus are among Wiley's specimens in his Miles City collection. 22 BULLETIN UNIVERSITY OF MONTANA. THE RUTULUS BUTTERFLY. Papilio rutulus, Boisduval. Fig. 18. Fig. 18, Papilio rutulus. Butterfly — It resembles P. daunus in color and markings, but the black bands are broader and it has not the two decided tails. The marginal spots on the under side of the fore wings run together, forming a continuous band. Expanse, male, 3.50-4.00 inches; female, 3.75-4.25 inches, 94 to 106 mm. This species also closely resembles P. turnus, and displaces turnus on the Pacific Coast. It is not uncommon. At Missoula it flies as early as May 10. At Swan lake it is abundant in June. It is found as high as 6,100 feet at Missoula. Food — It feeds on alder and willow, which are very abundant along all Mountain streams. Distribution — It is a Pacific species. Found throughout the western part of the state. Not reported at Miles City, except as mentioned under daunus. Brandegee reports it from Helena. It is fairly common at Boze- man, according to Cooley. BUTTERFLIES OF MONTANA. THE EURYMEDON BUTTERFLY. Papilio eurymedon, Boisduval, Fig. 19. 23 Fig 19, Papilio eurymedon. Butterfly — In the style of its marking it resembles P. daunus, but the ground color is always pale whitish yellow or white, and the white marginal spots on the under side of the fore wings continuous as in P. rutulus. Expanse 3.50 — 4.00, 87 — 100 mm. In the western part of the state it is the most abundant species, flying as early as April 30, and taken through May, June and July. Food — The caterpillar resembles P .turnus, but may be distinguished by its paler color and the much smaller spots composing the longitudinal series on the back and sides, and by the different color of the head. It feeds upon a variety of plants, and is especially partial to Rhamnus californicus. Distribution — The species ranges from Mexico to Alaska, eastward to Colorado. It is abundant in the valleys of the Coast ranges, and is very common in the canyon of the Frazer river, British Columbia, in June. Common, though not abundant, around Missoula, and taken in the Mis- sion mountains and at Swan lake. It has been taken at 6,000 feet at Helena by Brandegee. At Bozeman it is not very abundant (Cooley). Wiley has one specimen from Miles City. 24 BULLETIN UNIVERSITY OF MONTANA. BRUCE'S SWALLOWTAIL. Papilio brucei, Edwards, Fig. 20. Fig. 20, Papilio brucei. Butterfly — Expanse 3.25-3.60 inches. Under surface yellow, with black borders ,the same as in P. daunus. The base of the wings is black and it extends in such a way as to make the discal cell appear black with three yellow bars. It has the yellow spots in the black along the costa. It has one tail, and black marking on the veins. The last lunule in the hind wing is orange with a black ocellus. The hind wings have the blue clouds. The body is black. It is thought to be the result of a union be- tween P. oregonia and P. bairdi. Food — The caterpillar feeds on Umbelliferae, and is common on parsley and parsnips in gardens. Distribution — In Colorado and adjacent regions P. oregonia meets with the form bairdi which ranges northward from Arizona. Hybridiza- tion is thought to have occurred, resulting in the fixed form brucei, breeding either toward bairdi or oregonia. Oregonia is found in Oregon and Washington, where bairdi is absent. We formerly captured a speci- men identified by Edwards as oregonia and another as bairdi near Idaho Falls, which lends support to the hybridization idea. We have sought for oregonia in Western Montana, but have found none which could be so called. Most of our specimens have been taken from Missoula. One was taken in the Mission mountains. Cooley has specimens from Bozeman, thought to be zolicaon. Possibly Wiley's zolicaon may be brucei. BUTTERFLIES MONTANA. 25 THE ZOLICAON BUTTERFLY. Papilio Zolicaon, Boisduval, Fig. 21. Fig. 21, Papilio zolicaon. Butterfly — Expanse 3.25-3.75 inches. Upper side of primaries black, marked and spotted with deep yellow; of secondaries yellow from base nearly two-thirds the distance to margin, beyond black; primaries have a sub-marginal row of eight spots, and a discal series of eight forming a band across the entire wing; the first discal spot excavated on the upper side, sometimes divided into two. Secondaries with a broad black border which incloses a sub-marginal series of six yellow spots, the first often wanting; an orange or deep fulvous spot, inclosing a round or oval or black spot, and edged on the upper side by a blue crescent, the ring occasionally wanting; the rest of the wing yellow, divided into eight spots, the cell being one, by the black nervures. Under side nearly as above, the colors paler. Food — The caterpillar feeds on the Umbelliferae, fennel, carrot and celery. Distribution — Southward from Vancouver's Island to Arizona, east- ward to Colorado. Reported by Wiley to be rare at Miles City. Collected by Dr. Hayden in Montana in 1871. THE NITRA SWALLOWTAIL. Papilio nitra, Edwards. Butterfly — This butterfly is very nearly related to zolicaon, but the black is v/idely spread over the baso of the wings so as to make the yellow appear like a broad band, and the two yellow bars in the fore wings are very indistinct. Holland reports this insect rare in collections, and says it has sprung from the same original stock as zolicaon and aliaska, the latter being an offshoot from the Asiatic butterfly. We have not seen the species. Food — Early stages and food unknown. Distribution — It occurs in Montana and the portions of British America adjacent on the north. BULLETIN UNIVERSITY OF MONTANA.

Early Stages — Described by Edwards. "The caterpillar infests the pine trees and firs of the northern Pacific States. The larva lets itself down by a silken thread, often a hundred feet in length, and pupates on the ferns and shrubbery at the foot of the trees. It sometimes works great damage to the pine woods." Distribution — It does not seem abundant in the west end, but has often been seen in the Mission mountains and about the laboratory at Big Fork high up in the coniferous trees out of reach of the collector. At Swan lake it was found rather abundant late in August, 1903. In Auguist, 1904, about 40 were taken in a half hour, about half way up the lake. The collecting region at Swan lake for this species is along the lower half of the .° lake shore. Very few have been seen around the upper Neophasia menapia end. Genus PONTIA FABRICIUS. (The Whites).

Veins of hind wings are broadly marked with greenish yellow sprinkled with brown seals, and the tips of the fore wings tinged with greenish yellow. Female. Color and spots as in male, but the spots have a tendency to blend, and the outer margin supports a border of triangles connecting with the sub- terminal row of rays. Hind wings with subterminal zigzag blackish line, outer portions sending rays to the margin, where they are somewhat expanded. The base of both wings are more sprinkled with dark scales than in the males. Under side similar to that of the male. Winter form, vernal is, Edw. Smaller than summer form, the dark colors more prominent. Spots of subterminal row of fore wings more inclined to be connected. Expanse scarecely 1.6 inches. Body black, with some white hairs and scales. Distribution — This insect is usually known as the Southern Cabbage butterfly, though it is to be found everywhere east of the Rocky moun- tains. It is injurious in the larval state in the southern states. In the northern states P. rapae is more common, in many places driving out protodice. There are several broods during a season. Wiley has taken it at Miles City; Brandegee has collected it at Helena; Cooley has it from Bozeman; Douglass collected it in the Ruby Mountains and Madison Valley; Elrod has taken it at Missoula, Flathead Lake, and in the Mission Mountains, Coubeaux has it from Big Sandy. Collected by Coues along the 49th parallel in 1874. BUTTERFLIES OF MONTANA. Fig. 25, Pontia protodice. Its food consists of cruciferous plants. It is destructive to cabbage. THE WESTERN WHITE, Pontia occidentalis Reakirt Butterfly — Size about 1.75 inches, distinguished from P. protodice by its smaller size and different markings. On the under side of the wings the dark markings are not concentrated in blotches, but are in broad longitudinal rays on either side of the veins from the base to the outer margin. Spots on the upper side much smaller than in protodice, and fewer. The females are sometimes lemon yellow above. Early Stages — Similar to those of protodice. Distribution — It is found from the Rocky Mountains to the Pacific. Wiley has it in his collection from Miles City; Cooley has taken it at Bozeman; Brandegee at Helena; Douglass at Madison Lakes; Elrod at Missoula, and on MacDougal Peak. It is likely to be found any place in the state. Allen has taken it at Dillon. Coues collected it in 1874 along the 49th parallel. THE CABBAGE BUTTERFLY. Pontia rapae, Linnaeus. Fig. 26. Fig. 26. Pontia rapae; upper figures show both surfaces of female, lower figures same for male. 30 BULLETIN UNIVERSITY OF MONTANA. Butterfly — Known as cabbage butterfly; yellowish white, with apex of fore wings black. Two black spots on fore wings and one on the hind wings. Underneath, the apex of the fore wings and the entire surface of the hind wings are pale lemon yellow. In the female two spots on outer part of fore wings, in male only one. The larva feeds principally on cabbage. Its color is green like the cabbage leaf, with a narrow greenish lemon yellow dorsal band. The body is clothed with very fine short hairs. Distribution — This common species is an importation from Europe. It reached Quebec in 1860; how, no one knows, perhaps in cabbage. By 1881 it had spread over the eastern half of the continent, from Hudson Bay to Southern Texas. In 1886 it had reached Denver, and in 1884 had reached the head waters of the Missouri. It now possesses the cabbage fields from the Atlantic to the Pacific, "to the incalculable damage of all who provide the raw material for sauerkraut." The injury done by the caterpillar is estimated to amount to hundreds of thousands of dollars. It is probably to be found all over the state, and has been taken at almost every place where collections have been made, at Missoula, Miles City, Bozeman, Helena, University of Montana Biological Station at Flat- head Lake, Mission Mountains. It does not seem as common as P. protodice. Allen collected it at Dillon. THE MUSTARD WHITE. Pontia napi Linnnaeus. Fig. 27. 1 2 Fig. 27. Pontia napi, No. 1, var.pallida No. 2, van. acadica. Butterfly — Expanse of wings, about 1.75 inches. In general shape and appearance it resembles protodice or rapae. General color while, with grayish vein markings, some with a dusky spot on the wings, or dusky at the base of the wings. A Protean, cosmopolitan species, ex- isting in many forms, the result of climatic and local influences, which has a very wide distribution. The different forms are to be found from Arctic America as far south as California on the west, and Michigan and New England on the east. It is mostly represented in the regions farther to the north. The typical form is found in Europe, rarely in Nortu America, although Holland has specimens from the Pacific Coast region BUTTERFLIES OF MONTANA. 31 which he says are absolutely indistinguishable from European specimens in color and markings. Var. pallida, Scudder. The wings are white above and below, with small black spot on the fore wing of the female above, and hardly any trace of dark shading along the veins on the under side; a trace of dark on the hinder edge and base of fore wings.

Synchloe sara, upper and lower surfaces. Butterfly — White with orange tips. There is a black bar dividing the apical patch. The female is sometimes yellow instead of white. On the under side the hind wings are marked with dark irregular patches of greenish brown scales, loosely scattered over the surface, and having a "mossy" appearance. There are different varieties. Early Stages — Unknown. Distribution — This species in 'all its forms belongs to the Mountain States of the Pacific Coast. It is abundant around Missoula, where it seems to thrive. The mountain slope back of the University is a favorite field, as it faces the west, catching the warm rays of the sun in spring. Here dozens may be captured in a short time. It is common around Helena (Brandegee) and about Bozeman (Cooley). Var. julia, Edwards, in which the black bar dividing the red apical patch from the white on the remainder of the wing is broken, or tends to diminution at its middle, is reported by Brandegee as common at Helena. Variety reakertii is smaller than sara, with dark spots at the ends of the veins of the hind wings. Taken by Brandegee at Mt. Ascension, near Helena.

Lily Mordaunt in "Kenelm Chillingly" had some beliefs that make her too fanciful for a real character. One of the most conspicuous of these was her idea about butterflies. She had a green-house inclosed with wire and covered with vines and draperies, into which she put every butterfly she could catch. Butterflies to her were not insects, but the souls of infants who had died unbaptized. If they were taken care of for a year they turned to fairies. So she fed and tamed her colonies of but- terflies, releasing them when she believed their year of life completed,, that they might be free to change into fairies. NELLIE A. WHITNEY. Fig. 33. Venation «f Eurymns. BUTTERFLIES OF MONTANA. GENUS EURYMUS, Swainson. (The Sulphurs.) Fig. 33. Butterfly — Medium sized, yellow or orange in color, with black borders upon the wings. In many species this border is heavier in the female than in the male. Egg — The egg is spindle shaped, thickest at the middle, tapering at the apex and at the base, generally attached by an enlarged disk- like expansion, to the point on which it is laid. The caterpillar feeds upon Leguminosae and especially upon the clover. Distribution — This genus is represented throughout the temperate regions of both hemispheres. It also occurs in the cooler por- tions of South America and along the ranges of the Andes. Key to Species. 1. Ground color of wings yellow, no black at base; underside with a sub-marginal row of dark points, philodice. 2. Ground color of wings orange, or at least an orange patch in the middle of fore wings. Wings orange above and below, eurytheme. Wings deep orange above, green below meadii. 3. Under side without sub-marginal row of black spots.

THE COMMON SULPHUR. Eurymus philodice Godart. Fig. 34. Fig. 34. Eurymus philodice, left figure, male; right female. 38 BULLETIN UNIVERSITY OF MONTANA. Butterfly — Wings above rather pale greenish yellow, outer borders black; border of female is broader than in male, and contains a sub- marginal row of yellow dots; discal spot in the male is elliptical; an- tennae, costa and fringes roseate; a submarginal row of dots on the under side, the last three on the fore wings black, the remainder brown with pink scales. Dimorphic females occur with wings nearly or quite white, and also a black form. Expanse 1.75, 2.25 inches, 38-57 mm. Early Stages — The food plant is clover. The eggs are pale yellow, changing after being laid to crimson. The caterpillar is slender, green, striped longitudinally with paler green. The chrysalis is pale green. Distribution — The species ranges from New England to Florida and westward into the Rocky Mountains. The collection at the University of Montana contains specimens from Missoula, Fish Creek, McDonald Lake in the Mission Mountains, Lo Lo Hot Spings, Flathead Lake, Madi- son Valley, National Park and Mount Lo Lo. Remarks — It is one of our common butterflies. It shows many varia- tions in size, coloration and markings. We have despaired of separating the males of philodice, eurytheme and alexandra, so much are they alike, and so much do they vary. It would at first seem as though philodice should not be found west of the range, but specimens from Flathead Lake are indistinguishable from those in the eastern end of the state; and if the labels of Montana specimens were exchanged with those col- lected by Wiley and the writer from Iowa, Michigan, Illinois, and Mis- souri the difference could not be told. The large series (about 100) of insects of this species in the University collection shows that the species in markings and coloration apparently merges into Eurytheme, and it has often occurred to us that they may possibly overlap. THE EURYTHEME SULPHUR. Eurymus eurytheme, Boisduval. Plate IV. Butterfly — Expanse of wings 2 to 2.35 inches, 50-90 mm. Closely re- sembling philodice in size, shape and markings, but color orange, of varying shades, instead of yellow. Male usually orange-yellow, shading to sulphur yellow on the costa of both wings and on inner margin of hind wings, base and inner margin sprinkled with black scales; outer border black, broadest at apex; anterior veins yellow where they cross the black; width of border about one-fourth the length of wing; discal spot black on fore wings, orange on hind wings, usually with two spots in the latter; both wings have roseate reflection; under side yellow, middle of fore wings tinged with orange; on both wings a sub-terminal row of dots, the three posterior of fore wings black, the remainder brownish, also two dots on costa near apex; discal spots repeated, the anterior black, with a few light scales, posterior gemmate, silvery, an- nulate with roseate brown or ferruginous; a dash on the costa of the hind wings near the apex, and a rosy spot at the base. Female of same general color; border contains a row of yellow spots, the third from the posterior and on fore wings sub-obsolute; border of hind wings wider than in male, and with rudiments of yellow spots; under side similar to that of male.

Distribution — The range of eurytheme is very wide. It extends from the Atlantic to the Pacific, and from Canada to the far south, though it is rare in the south. It has been collected in the state by Elrod at Flathead Lake, Missoula, Mission mountains, Dodge Mountain at 7,400 feet, and Mount Lo Lo. Douglass has taken it at * ish Creek, Laurin, Ruby moun- tains, Tobacco Root range, and Madison valley; Wiley has collected it at Miles City, Brandegee at Helena and Gold Creek, and Cooley at Boze- man. It is found in all parts of the state, and will be one of the first specimens captured by the young entomologist. The reader is referred to "Remarks" under philodice. Coubeaux says form eriphyle is very common near Big Sandy. Allen has taken eriphye, ariadne and keeway- den at Dillon. Coues collected keewayden and eriphyle along the the 49th parallel in 1874. 40 BULLETIN UNIVERSITY OF MONTANA. THE ALEXANDRA SULPHUR. Eurymus alexandra, Edwards, Fig. 36. Fig. 36 Eurymus alexandra, female with expanded wings; male showing unuer side. From specimens taken at Bigfork. Butterfly — Expanse of wings of females 2-2.3 inches, 50-60 mm.; of males, 1.75 inches, 45 mm. Male pale canary yellow, the black border much narrower than in philodice or eurytheme; a fine yellow line borders the black on outer margin; base of wings, thorax and abdomen with considerable black; anterior of thorax, antennae and legs roseate; under side of fore wings much paler than upper, uniform; under side of hind wings pale greenish gray, sprinkled with black scales; discal cell of hind wing silver, without rings; black border above showing through wing from below. Female larger than male, without black border above; sometimes the apex of fore wings is sprinkled with black, giving indica- tions of markings; wings paler than in male, sometimes almost white; discal spot in fore wings black, oval, sometimes with yellow splash in the middle; on hind wing orange yellow, usually double; under side, silvery gray, yellow only at the base and on inner margin of the prim- aries; discal spot of hind wings silvery, with brown margin. Discal spot of fore wing dark brown with light spot in center; the roseate of the male repeated on the female, continuing around the outer border of the wings. Early Stages — Caterpillar uniformly yellowish-green, with a white band on each side, broken with orange dashes running through it. The chrysalis resembles that of philodice, is yellowinsh green, darkest on the BUTTERFLIES OF MONTANA. 41 dorsal side, and adorned with three small red dots on the central side of the abdomen near the wing cases. The caterpillar eats Astragalus, Thermopsis and white clover. Distribution — The species is found in Colorado and the Mountain region to the north and west of that state. In Montana it has been taken at the University of Montana Biological Station at Bigfork, in 1903, at Flathead lake. It is not common, and is rather difficult to catch, as it keeps to the bushes and does not rest often. Brandegee has collected it at Alhambra. A single frazzled and battered female was taken by Elrod on MacDaugal Peak in the Swan range at 6,500 feet August 4, 1903, and another August 1, 1904. SCUDDER'S SULPHUR. Eurymus scudderi, Reakirt. Butterfly — Expanse, 1.80 to 2.00 inches, 45 to 50 mm. Similar to- alexandra. The male on tae upper side is colored like C. pholidice, but the black borders are much wider. The fringes are rosy. The female is generally white — very rarely slightly yellow — with very pale dark bor- ders, or often without any trace of black on the outer margin of the wings. On the under side the apex of the fore wings and the entire surface of the hind wings are greenish gray. The discal spot of the secondaries is well silvered and margined with pale red. Early Stages — The larva feeds on the leaves of the huckleberry and willow. Otherwise it is unknown. Distribution — The species is found in Montana, Colorado, Utah, and British Columbia. Wilsey's collection contains one specimen from Miles City. We have not taken it west of the range. STRECKER'S SULPHUR. Eurymus meadii, Edwards, var elis Strecker. Plate IV and Fig. 37. Fig. 37. Eurymus meadii, var. elis, left hand, female; right hand, male. Butterfly — Expanse of wings 1.85 inches, 48 mm. Male; deep orange red above, with wide black border fringed with red; wing veins in both wings showing through black; black border covering outer third of fore wings, a little less of hind wings; fore wings black at base, extending to hinder angle of wings as a widening wash, ending in black scales over the orange ground; posterior edge of the hind wings with greenish gray 42 BULLETIN UNIVERSITY OF MONTANA. from 2 to 5 mm. wide, bordered exteriorly by the black border above showing through; discal spots above deeper orange than ground color; below, discal spot on fore wings small, dark brown, on hind wings light silver with red border; legs, antennae, anterior of thorax, hairs of head and fringe deep rose red; sometimes the outer anterior angle of the fore wings and the posterior angle of the hind wings above and below suffused with deep red. Female, similar in general color to male, less pronounced, and if anything, lighter; discal spot on anterior wings black, showing through on under side; discal spot on hind wings similar to male; less black at base of wings, posterior edge of lighter color than in male; black border not so wide as in male, with dashes of much lighter orange than ground color; dashes suffused at anterior angle of hind wing; under side as in male; rose red antennae, thorax, head, legs, and fringe as in male. Early Stages — Holland says "closely resembling those of meadii, of which it may be only a varietal form. Distribution — It is recorded as inhabiting the lofty peaks of the Western Cordilleras. It has been taken by Douglass at Fish Creek, August 16, 1900, and in the Tobacco Root Range July 14, 1900. Remarks — It differs materially from the meadii in the writer's col- lection taken at Pike's Peak in 1892. Elis as described above from Mon- tana is larger in both sexes than meadii, has much less green, and with decidedly different washings of orange on the borders of the wings of the female. This female meadii has much more red in the ground color than in elis. The meadii were taken at 12,000 feet and elis at about 8,000 which would of course make some difference. We have taken neither meadii nor elis west of the main range. BUTTERFLIES OF MONTANA. 43 Collecting Butterflies at High Altitudes in the Andes. While forming these collections I was led to remark the frequency with which closely similar forms recurred at similar altitudes, upon mountains often long distances apart. This was observed in regard to things living in the soil, as well as in respect to winged insects of roving habits. It was not unusual to see butterflies, at closely similar altitudes upon widely separated mountains. This was the case with a Lycaena that has not been described which was taken at 11-12,500 feet on Pichincha and thirty-six miles away at 12,000 feet on Colocachi, and was not seen elsewhere. But, for the most part, butterflies which were taken at considerable elevations were also found on the connecting, lower ground. Thus Pieris xanthodice, Lucas, though captured so high as 14,000 and 15,000 feet, was found everywhere in the intervening basins; and as, even had this not been so, it would need little effort for them to pass from one mountain to another, and further as they may sometimes suffer involuntary transportation, no particular stress can be laid upon such instances of occasional recurrence at similar elevations. One Butterfly, however, was exceptional in being found upon nearly all the mountains visited, in numbers, and seemed to be established be- tween the elevations 12,000 — 16,000 feet. This is described by Messrs. Goodman & Salvin, at p. 107 of the Supplementary Appendix, as Colias alticola. It was first obtained near Tortorillas, Chimboraza (13,000 feet), and was seen in the Vallon de Carrel as high as 16,000 feet. When we were camped upon Antisana it attracted attention by the great elevation above the level of the sea at which it was flying (16,000 feet). It was seen subquently upon all the mountains we visited (except Sara-urcu) between the elevations of 12-15,000 feet, and was captured at 12,000 feet on Pichincha, on 13,000 feet on Cayambe, and at 15,000 feet on the western side of Chimborazo, and was never either taken or seen in the basins between these mountains.

The family includes chiefly butterflies of medium or large size; but a few of the species are small. With a single exception, these butterflies differ from all others in our fauna, in having the fore legs greatly reduced in size in both sexes. They cannot be used for walking, but are folded on the breast like a tippet. In the venation of the wings all of the branches of the radius of the fore wings are retained, this vein being five branched. (Fig. 38). The caterpillars are, in most of the sub-families, provided with horny or fleshy projections. The chrysalids are usually angular, sometimes rounded. They always hang head downwards, supported only by the tail, which is fastened to a button of silk. Five sub-families are represented in the United States, but three of the five in Montana. The following key will serve to separate them. FAMILY NYMPHALIDAE. Key to Sub-families. 1.

BUTTERFLIES OF MONTANA. 47 The Seasonal Migration of Anosia Plexippus. The range of Anosia plexippus is from Patagonia to Hudson Bay. It has not been found in hibernation and, considering its size and con- spicuous coloring, it may well be said that it does not pass the winter North of latitude 31 degrees. A careful study of its range, time of appearance, and habits, shows unquestionably that there is a seasonal migration of this very interesting form. Riley first suggested these movements, when state entomologist of Missouri, in the following words: "There is a southward migration late in the growing season, in congregated masses, and a northward disp?r- sion early in the season, through isolated individuals." The more evident movement is in the fall, when in the Mississippi valley and along the Atlantic Coast, the September air seems to be full of brown butterflies, usually apparently taking advantage of the cooler winds from the North, though many times bravely beating into the winds with a very strong flight for a butterfly. The Aster patches growing along the roadside and in neglected fields seem to be the favorite places of assembly. At such times a zoology class has no difficulty in provid- ing themselves with material. In fact an active boy with a net can catch them by the hundred in one afternoon. The collecting together of siich numbers was formerly accounted for by the presence of plenty of food. This alone seams inadequate, since many fields, equally inviting, will contain a normal population. It seems likely that a swarm may busy themselves in this way in the fields, await- ing favorable winds. We must pause to consider the probable absence of initiative on the part of the insect. It is more likely influenced by the temperature, the North wind being the cooler, and, for seme reason not explained, awakening in the insect the dormant instinct of migration. An instance of the gathering of thousands of Anosia in one tree and the fact that they remained there with occasicnal short excursicns, until a change of wind and temperature, was noted in Bu lingtor, lo ^ a, the last week of September, 1905. The f:ct that these insects alight on trees in such swarms as to give the'r color to the tree, his been cfcen recorded. Tnis is not the only evidence of their flocking. There is the best of authority for stories of southward migration. Some have re- ported clouds so dense as to at times cast a shadow. Dr. Scudder le- lates a flight on September 2, in New Hampshire, when the southward flight of a swarm was observed by himself. He states that they stretched out in a thin stream that occupied hours in passing. He esti- mated that in a limited field in front of him, they were passing at the rate of 1,500 per hour. It is little wonder that they are said to fill a tree, bending the twigs to breaking with their weight. Granting that these accounts of large numbers of Anosia in one swarm are exceptional, we can see that spread over this broad land there must be countless mil- lions moving southward every autumn. What advantage, if any, is gained in the association of these insects in swarms, is not easily dis- cerned. 48 BULLETIN UNIVERSITY OF MONTANA. The fact of Northward movement in the spring is not so easily estab- lished. As before stated the Anosia is not reported to have been found North of latitude 31 degrees in the winter. When Spring opens nsither the egg, pupa or adult is to be found. The milkweed is a foot high in Iowa and much good fodder is awaiting the larvae, before the adult makes its appearance, and lays eggs on the tender unfolding leaves near the tip of the growing plant. Some say that the appearance is not that of a tattered "left over," as is usually the case with hibernating species. They appear as a whole to be a fresher and newer lot; though I have seen some that looked a good deal the worse for wear rather early in the sea- son. There seems little doubt, however, that the new arrivals have not hatched in our region, since there has been no opportunity for larvae to develop and pupate. It seems more probable that they are the spring brood from an earlier season in the south. We must not, however, con- luse them wuh those that disappeared in that direction last fall. In Southern Iowa it seems probable that the eggs laid by the first arrivals produce a new brood in July. These in turn produce the brood that soon after arriving at maturity southward. We seem to have two broods; while New England and northern climes have one only, and that one, from the eggs of the first brood hatched in our latitude. The northward migration is continued to Hudson Bay and north of the range of the food plant of the larvae; a significant fact, in itself, proving the migration of the species. The northern boundary of the food plant limits the adult of other species sharply. This is noticeably the case with Papilio ajax in southern Iowa, where a species very abundant south of us is limited by the food plant, the Pawpaw, which disappears near the 40th parallel. There are several known peculiarities of this insect that especially fit it for this sort of a life. The well known immunity from molestation by insectivorous birds, the comparatively long intervals between oviposi- tion, enable a butterfly of this species to scatter its progeny over a great territory, since but one egg is laid in a place. The slow northward movement of the season in spring allows time for additional broods fur- ther South. The adults that first arrive here in the spring are sup- posed to be from larvae grown several hundred miles to the southward, where there may be four or more broods in one season. This north- ward movement may therefore be considered a sort of a relay race. The returning hosts contain none of the brood that came northward, since the life of an insect after final oviposition is usually short and its excuse for existence has expired. Granting that the seasonal migration of this butterfly is established, we may say that this is merely another way in which nature replenishes the earth after the life destroying frosts of winter, so fatal to insect life. Hibernation has its advantages, and does not call for so complex an adap- tation. Why Anosia has this different means of preservation is as much a puzzle as ever. This illustrates anew a striking observation by Mr. Frank Springer, the paleontologist, when sepaking of the marvelous, perfection to which an organism may be brought through a period of development, only to be apparently discarded and the whole problem worked out in an entirely different way in succeeding forms. He says BUTTERFLIES OF MONTANA. 49 that "it seems as though Nature delights to show in how many different ways the same result can be accomplished." In this case, it seems as though the combination of the striking adaptations of Anosia have made it second only to the Pieris rapae, or "cabbage butterfly", in numbers and distribution over the earth. In recent times this insect has spread to Australia, and from there to all the East Indies and the Philippines. It is captured in Europe with increasing frequency, and will doubtless be as successful in the old world as in the new. It is a harmless species and will not prove as un- welcome as has the little white pest in this country. We may wish it success in its efforts to colonize the East, and fear no reports of mis- behavior to discredit the benefits to be derived from New World ex- pansion. As a rule we have given them few plants and animals that have merited their disapproval. The Phylloxera is a notable exception, since it threatens the vinyards of the Old World. On the other hand you can hardly name a weed or obnoxious animal in this hemisphere that iias not been imported to our country. At all events the behavior of Anosia will be watched in the Old World with a growing interest to see if it will there develop any new and interesting traits. MAURICE RICKER. Burlington, Iowa, September, 1905. 50 BULLETIN UNIVERSITY OF MONTANA. SUBFAMILY NYMPHALINAE. The Nymphs. Butteryfly — The butterflies of this subfamily are mainly of moderate or large size, though some of the genera contain quite small species. The antennae are always more or less heavily clothed with scales, and are usually as long as the abdomen, and in a few cases even longer. It is impossible to briefly describe these butterflies because they vary so much. It is the largest of the subfamilies. Key to Genera. 1. Palpi nearly connivent, porrect 2. 2. Eyes naked 3.

Fig. 40. Fig. 40. Euptoieta claudia, from Miles City, showing upper and lower surfaces. Butterfly — Expanse of wings from 1.75 to 2.75 inches, 45-70 mm. Upper side of both wings fulvous or dull ferruginous, darker toward the base, crossed by an irregular black median line, which is darker, broader, and more zigzag on the fore wing than on the hind wing. This line is fol- lowed outwardly on both wings by a pair of more or less blackish spots. The outer' margin is black, fringes pale fulvous, checkered with black at the end of each nervule. At the end of the cell in the fore wing there are two black lines inclosing paler fulvous spots, and both wings near the base have some curved black lines. Under side of fore wings fulvous to the zigzag line, with discal pale spot. The outer half of the wing is pale, with a little submarginal red- dish wash below the apex, and a large gray triangle on the costa. A brown spot near the posterior angle sends a marginal streak toward the apex. The hind wings are pale brown in the basal half, streaked with white along the veins, and with transverse striae of darker brown. Beyond the middle they are whitish, shading off into the same brown as the base, with more or less whitish along the margin, the anal portion of the outer half being nearly as dark as the base, while the costal portion is almost white. There are about three indistinct marginal ocelli. Early Stages — The egg is conoidal, depressed at top, flat at base marked by about twenty longitudinal ribs, half of which reach the sum- mit. Mature larva is 1.2 inches, 28 mm., cylindrical, of an orange ochre color, smooth, striped longitudinally with black, which is almost con- cealed by the white spots that cover it. The chysalis is .8 inch, 21 mm. long, pearl white, irridescent, marked with dark brown patches and points, On the abdomen there are four rows of conical tubercles. There are two or three broods during a season, the last one probably hibernating in the larval state. It feeds on violet, passion flower, mandrake, Sedum, Desmodium, and Portulaca. 52 BULLETIN UNIVERSITY OF MONTANA. Distribution — The species has been taken as far north as Long Island and Connecticut, though it is a rare visitor in New England; ft is quite common in Virginia and thence southward, and occurs not -infrequently in southern Illinois and Indiana, ranging westward and southward over the entire continent to the Isthmus of Panama, and thence extending over the South American Continent, wherever favorable conditions occur. In Montana it has been taken by Cooley at Forsyth and in GSllatin County, and by Wiley at Miles City. At the latter place it is common, but averaging smaller in size. The species seems to be confined to the Great Plains region of the state, although later collections may show it farther west than it seems from present records to be. THE REGAL FRITILLARY. Speyeria idalia, Drury. Fig. 41. Fig. 11. Speyeria idalia, Drury. Butterfly — Expanse of wings from 2.75 — 3.C inches, 70-90 mm. Male. Upper surface of fore wings fulvous, black along the costa, with a black outer border which is a little wider than the costal border; base and hind margin brown; three black bars in cell, another bar at the end with an open S united to it enclosing a fulvous spot; beyond the cell runs a transverse zigzag line, a submarginal row of black dots, and next the border a row of black crescents. Hind wings black, with violet re- flections; base of wings washed with fulvous; a black spot in cell, an irregular row of yellowish spots beyond cell, and a marginal row of ful- vous spots; fringes alternate spots of black and white. Under side of fore wings fulvous, white along the costa, a marginal row of silver spots enclosed in black crescents, and some silver on the costa near the apex; black of upper side repeated; under side of hind wings yellowish brown, with twenty-nine silver spots and patches, besides some silver shading. Female differs from male in being larger, with broader terminal band, which contains a row of white spots, witn six or more white spots near the apex, the outer row of spots on the hind wings of same color as the inner. BUTTERFLIES OF MONTANA. 53 Early Stages — Egg conoidal, truncated, rounded at base, marked ver- tically with eighteen ribs. Larva hatches in about twenty-five days. Larva at maturity 1.75 in., 45 mm., long, velvety black, banded and striped with ochre yellow changing to dull orange or red, and furnished with six rows of fleshy spines, each with several black bristles; head red above and black beneath. Chysalis an inch long, brown and yellow on ab- domen, remainder pinkish brown or brown. The larva feeds on violets. Geographical Distribution— Wiley has collected it at Miles City. It is not reported from other places, and the Wiley collection has but a single specimen. It is reported as common from Maine to Nebraska. It is to be expected the species would be found in the eastern end of the state. In the eastern states it is rather local, and frequents open spots on the borders of woodlands. At times it is apparently common, and then for a succession of seasons is scarce. It flies from the end of June to the be- ginning of September. 54 BULLETIN UNIVERSITY OF MONTANA.

Butterfly — The expanse of wings of specimens in the eastern states. is from 3 to 4 inches, or 76 to 102 mm. Upper surface fulvous or yel- lowish brown, more yellowish in the male than in the female. In the cell of the fore wings five black bars, except in the fourth bent outward in the lower half, the two outer united above. Beyond the cell are the usual zigzag black line and the subterminal row of dots, the middle ones of the fore wings the largest. Just within the outer margin is a termnial narrow line, and within this, and on the fore wings with their points rest- ing on this line, is a row of crescents; the fore wings edged with the same color. The cell of the hind wing with three more or less distinct bars. Under side of fore wings pale yellowish brown, the apical space yel- lowish and enclosing a bright brown costal patch; the lines and dots the same as above, but near the apex more brown. The apical five or six of the spaces enclosed within the submarginal crescents are wholly or partly silver, with three silver patches within this line. BUTTERFLIES OF MONTANA. 55 The hind wings have the basal two-thirds reddish brown more or less mottled with yellow, the outer boundary of this color a row of seven silver spots. Outer margin brown, fading into yellow at the anal angle, and within this another row of seven large silver spots rounded within and edged with brown. Between these two rows is a bright yellow band without spots. Fig. 42. Argynnis cybele. Early Stages — The egg is short, conoidal, ribbed like those of other species, and honey-yellow. The larva in mature state is 1.8 to 2 inches long, velvety black, chocolate-brown underneath. The body has six rows of slender black spines, generally ornamented with orange red at the base, and beset with many short black bristles. The caterpillar is nocturnal, and feeds on violets. It hibernates immediately on hatching from the egg, feeding to maturity the following spring. The chrysalis is dark brown, mottled with reddish brown or slaty grey. Distribution — It is from the Atlantic west- ward to Nebraska. Barber, 1894, reports it from the northwestern part of Nebraska. It has been taken at Edmonton, B. C., where it was found flying with A. la is by Captain Gamble Geddes, in 1883. A single specimen is in the Wiley collec- tion from Miles City, taken June, 1900. It is a A4rgyn^rsn!eto1! °f trifle less than three inches expanse, and placed side by side with specimens from Michigan, Ohio, and Illinois is indis- tinguishable from them. It has been taken at no other place in the state, and only the one specimen has been taken at the present writing. 5G BULLETIN UNIVERSITY OF MONTANA. THE LETO BUTTERFLY. Argynnis leto, Edwards. Figs. 38, 43, 44, 45. Fig. 44. Argynnis leto, male. Butterfly — The male on the upper side is a dull fulvous with the characteristic black markings of the genus; the basal area is darker. The under side of the fore wings is plae fulvous upon which the mark- ings of the upper side reappear. Both wings on the under side, are shaded with brown toward the base; the hind wings are traversed by a sub-marginal band of light straw yellow. The female is marked as the male, but the general color is pale straw yellow, and all the darker markings are deep blackish brown, those at the base of both wings being broad and running into one another, so that the inner half of the wings appear to be broadly brownish black. On the under side it is also marked the same as the male, but with the dark portions blacker and the lighter portions pale yellow. The marginal row of light spots on the hind wings appears on the under side as silver crescents; there are three rows of silver spots on the brown part of the wing. Expanse 2.50 to 3.25 inches, 64 to 83 mm. Early Stages — Unknown. Distribution — It occurs in California, Oregon and Montana. In Mon- tana it is found on both sides of the mountains. In the western part it is abundant about Flathead lake. It is a beautiful insect, demanding the attention of the collector, frequenting the more open woods, skirting the bushes by the roadsides, or frequenting the sunny open places in the woods. It has been taken, in addition to that mentioned, at Mount Lolo, Missoula, the Mission Mountains, and the Yellowstone Park by Elrod, at New Chicago by Douglass, at Helena by Brandegee, and at Miles City by Elrod. A male was collected at Miles City in July, 1893, and a female in Yellowstone Park in September, 1894, both identified by Edwards. It is likely to be found in most parts of the state, and will ornnament any BUTTERFLIES OF MONTANA. 57 collection. Allen reports a female nokomis from Dillon.

The black markings similar to cybele and leto. The median zigzag line is often broken. The two lines at the outer margin of the female are more or less blended, and the two are present on the hind wings of both sexes. The under side of the fore wings is pale reddish fulvous, the apical portion and along the costa buff, with pale brown markings; six marginal and three sub-marginal silver spots. The 58 BULLETIN UNIVERSITY OF MONTANA. iind wings are cinnamon brown with a narrow sub-marginal band. The silver spots are more or less edged with black. Early Stages — The eggs are short, conoidal, honey yellow and ribbed. The caterpillar has a velvety black spot at the base of each spine, the chrysalis has the tubercles on the back short, and the basal segments are partly colored. The caterpillar feeds on violets. Distribution — It is found in the northern and middle western states. Taken in the state by Wiley at Miles City, and by Elrod at Missoula. Cooley has one specimen from near Bozeman at 4,200 feet, July 20. Cou- beaux reports it common in Bear Paw Mountains. Var. alcestis, Edwards, Fig. 47, the Ruddy Silver-spot is very much like aphrodite, but distinguished from it by the fact that the hind wings are uniformly dark cinnamon brown, without any band of buff on the outer margin. It is of the same expanse as aphrodite. It is said to largely replace aphrodite in the western states. Indeed, there is likely to be difficulty in separating alcestis from the true form of aphrodite. Fig. 47. Argynnis aphrodite, var. alcestis, lower side. Alcestis has been taken by Elrod at Missoula and Flathead Lake, by Douglass in the Madison valley. The latter closely resemble aphrodite from Miles City. By far the greater number of specimens examined are aphrodite, and not var, alcestis. BUTTERFLIES OF MONTANA. EDWARDS FRITILLARY. Argynnis edwardsii Reakirt, Fig. 48. Fig. 48. Argynnis edwardsii, upper and lower surfaces. Butterfly — Expanse of wings 2.30-3.00 inches, 55-75 mm. Ground color pale fulvous, but little obscured with fuscous at base; a heavy black border at base; at least heavier than in nevadensis; lighter buff than nevadensis, under side of hind wings with large silver spots, olive brown color; the olivaceous of the wings encroaches on the marginal band. It may be known by its large size, by the long and pointed fore wings, and by the great size of the silver spots that ornament its under side. Distribution — According to Holland the species is not uncommon in Montana and Colorado. In Montana it has been taken by Wiley at Miles City, Douglass at New Chicago, and Fish Creek. Collected by Coues in 1874 on Chief Mountain. Remarks — Attention was called In the introduction to specimens identified by Edwards. One specimen sent by Wiley and another by Elrod from Miles City in different years were identified respectively as nevadensis and edwardsii. When placed side by side they are indis- tinguishable either in size or markings. Larger specimens from low ele- vation are likely to be called edwardsii, smaller ones from higher eleva- tion nevadensis. We believe that experiments in breeding will show the two species to be one. BULLETIN UNIVERSITY OF MONTANA. THE NEVADA FRITILLARY. Argynnis nevadensis, Edwards, Figs. 49, 50. Fig. 49. Argynnis nevadensis, upper side. Butterfly — Expanse of wings, male, 2.50-3.00 inches, 63-75 mm.; female, 3.00-3.50 inches, 75-88 mm. The ground color is pale fulvous, but little obscured with fuscous at the base. The outer margins are heavily bordered with black. The dark markings of the discal area are not heavy. The fore wings on the under side are pale buff, the spots well slivered; the hind wings are greenish; the belt is narrow and clear, and the spots are large and well slivered. The female is much like the male, but larger and paler. The outer margin of the fore wings in the female are more heavily marked with black and marginal spots are light buff in color. "It is allied to Edwardsii in shape, and forms a sub-group with it. It is brighter colored, smaller sized, and beneath the ground color is yellow and buff, mottled in the male with pale olive-green, and in the female with darker buff" (Edwards). Distribution — This species is found in the Rocky Mountains of Utah, Nevada, Montana, and British America. Specimens have been taken from Tobacco Root range by Douglass; Missoula by Elrod; Swan Range, 7,600 feet, by Elrod; Lolo Hot Springs by Elrod; Mount Ascension near Helena, by Brandegee; Shields river, 9,000 feet, Gallatin Valley, East Flathead, Park county, by Cooley. It thus ranges from 3,200 feet to 9,000 feet altitude. Collected by Coues in 1874 at Three Buttes, August 8 BUTTERFLIES OF MONTANA. (11 Fig. 50. Argynnis nevadensis, lower side.

The under side of the fore wings is pale ferruginous, tinged with a little buff at the tips. The under side of the hind wing is dark ferruginous with a narrow buff sub-marginal band. Ground color of the female is paler than the male. In neither are the light spots marked with silver; they are opaque, yellowish white. Ex- panse. 2.25-2.40 inches, 57-61 mm. Early Stages — The life history remains to be learned. Distribution — The butterfly is found among the mountains of Colo- rado and Montana. G2 BULLETIN UNIVERSITY OF MONTANA. It has been taken by Elrod in the National Park, at Missoula, in the Swan Range, and on Mount Lolo near Missoula. Cooley has a specimen from Bozeman at 4,800 feet. Brandegee collected it near Helena, and Barnes at Aldridge. Rare in the Bear Paw Mountains, according to Cou- beaux. THE RHODOPE SILVER-SPOT, Argynnis rhodope, Edwards. Butterfly — Expanse, male, 2.20 inches, 55 mm.; female, 2.40 inches, GO mm. The upper side of the male is bright fulvous, both wings on the inner half heavily clouded with dark fuscous. The black markings are very heavy and confluent. The outer border is solid black, very slightly, if at all, interrupted by a narrow marginal brown line, in this respect resembling atlantis. On the under side the fore wings are dark ferruginous, on the outer margin rich dark brown. Between the spots at the end of the cell and the nervules below the apex are some clear, bright straw-yellow spots. The upper spots of the marginal series are silvered. The hind wings are dark reddish-brown, very slightly paler on the line of the marginal band. The spots are pale straw-yellow, except those of the marginal series, which are distinctly silvered. The female on the upper side is of a lighter and brighter red, with the markings dark and heavy as In the male sex. On the under side the markings in the female do not differ from those in the male, except that the primaries on the inner half and at the base are bright pinkish-red (Holland). Early Stages — Unknown. Distribution — The insect flies in British Columbia. Coues collected a single female August 8, 1874, near Three Buttes, Montana. This is the only record of its capture in the state. BREMNER'S SILVER-SPOT. Argynnis bremneri, Edwards. Fig. 52. Fig. 52. Argynnis bremneri. Butterfly — Expanse, 2.4 to 2.7 inches, 60 to 70 mm.

Both wings at, the base are BUTTERFLIES OF MONTANA. 63 clouded with, fuscous, the under side of a primaries red toward the base, buff on the apical area; the sub-apical and the upper marginal spots well silvered; the hind wings with the inner two-thirds more or less deeply ferruginous, a little mottled with buff, very rarely encroached upon by the dark color of the inner area, except occasionally near the angle (Holland). Early Stages — Undescribed. Distribution — Found in Oregon, Washington, Montana, southern por- tions of British Columbia and Vancouver's Island. Specimens in the University of Montana collection from Flathead lake by Elrod, and from Tobacco Root Mountains by Douglass. The specimens show the under side of lighter color than from Vancouver, but with the characteristic heavy black markings. THE ELECTA SILVER-SPOT. Argynnis electa, Edwards. Butterfly — Expanse, 2.00 to 2.25 inches, 51 to 64 mm. The male is dull-reddish fulvous on the upper side. The black markings are narrow. The base of both wings is slightly obscured. On the under side the fore wings are pale cinnamon-red, mottled on the disk with a little buff. The sub-marginal band is buff, quite narrow, and often invaded by the ground color of the inner area. The silvery spots are usually very well marked and distinct, though in a few instances the silvery color is somewhat obscured. The female has the black markings a little heavier than the male; otherwise there is but little difference in the sexes (Holland). Early Stages — Unknown. Distribution — Among the mountains of Montana and Colorado. Hol- land says it is often confounded with atlantis, but is wholly distinct, smaller in size, the fore wings relatively broader, and the markings not so dark on the upper surface. We have not taken it. THE MOUNTAIN SILVER-SPOT. Argynnis atlantis, Edwards. Fig. 53. Fig. 53. Argynnis atlantis, upper and lower surfaces. BULLETIN UNIVERSITY OF MONTANA. Butterfly — Expanse of wings, 2.25-2.50 inches, 55-65 mm. Upper sur- face fulvous, obscured by brown scales on the fore wings from the second bar in the cell obliquely to below the median zigzag line on the hind margin; the two marginal lines so blended that not much of the ground color is left. Marks as in A. aphrodite. Under side of fore wings reddish fulvous, costa and apex light buff, the apical patch and outer margin brown, with the apical silver spots, six marginal, three sub-marginal; hind wings dark red brown, much mottled with greenish gray or drab, the sub-marginal band pale yellow, usually pure from margin to margin. Silver spots as in aphrodite. This insect resembles aphrodite; it is distinguished from that species by its smaller size, its somewhat narrower wings, the deeper color of the base of the wings on the upper side and their darker color on the under side. The sub-marginal band is pale yellow, narrow, but distinct and always present. Early Stages — The egg is conoidal, with twelve to fourteen ribs, honey yellow. The caterpillars are hatched in the fall and hibernate without feeding until the following spring. Caterpillar — The head is dark blackish brown. The body is velvety- purple above, a little paler on the underside. The usual spines occur on the body, and are black, grayish at the base. The larva feeds on violets. Crysalis — Light brown, speckled, except on the abdominal segments, with black. Distribution — The species has a wide distribution. It ranges from Maine to the mountains of western Pennsylvania, thence southward along the central ridge of the Alleghanies into West Virginia. It is found in Canada, extending westward into the Rocky Mountains. In the state it has been taken at Missoula, Mount Lolo, and Flathead Lake by Elrod, and at Bozeman by Cooley. It does not seem to be repre- sented *n Wiley's collections. According to Coubeaux it is common in the Bear Paw Mountains. THE EURYNOME FRITILLARY. Argynnis Eurynome, Edwards. Fig. 54. Fig. 54. Argynnis eurynome. BUTTERFLIES OF MONTANA. 65 Butterfly — Expanse, male, 1.70-2.00 inches, 45-50 mm.; female, 2.00 inches, 50 mm. The wings on the upper side of the male are bright yel- lowish fulvous, but little obscured at the base. The outer margins are edged by two fine lines which are occasionally confluent. The under side of the fore wings is pale buff, laved with cinnamon brown at the base and along the nervules; the spots on the margin and in the apical area are well silvered. The hind wings on the under side are buff, with 'the basal and discal areas mottled with pale brown or pale olive-green. The marginal belt is broad and clear buff; all the spots are well silvered. The female is like the male, but paler, with the dark markings, espe- cially those of the margin, heavier; the marginal spots inclosed by the lunules are much paler than the ground-color, and in many specimens almost white. On the under side the wings in this sex are like those of the male, but the fore wings are more heavily laved with ciannamon- brown at the base. Early Stages — The egg has been figured by Edwards, otherwise we must say unknown. Distribution — Common in Colorado, Montana, and British America, showing much variation. Dyar calls erinna, bischoffi, artonis, clio, arge and cunninghami varieties of the species. Eurynome has been taken in the state by Cooley at Bozeman, 4,800 feet, and 9,500 feet; by Elrod in the Swan Range at 6,500 feet, Flathead at 3,000 feet, and Mount Lolo; by Douglass in the Tobacco Root Mountains 8,000 feet, Madison valley, Ruby Mountains; by Brandegee on Mount Ascension and near Helena, and by Barnes at Aldrich. Coubeaux says it is rather common in the Bear Paw Mountains. Allen has collected it at Dillon. Var. Clio, the Clio Fritillary. The spots on the underside are with- out silver. Otherwise like the type. Taken by Cooley in Gallatin County at 6,800 feet elevation, and at Shields river at 6,700 feet. A specimen with very little silver was taken by BJirod in the Swan range at 6,700. A female taken by Dr. Coues at Chief Mountain August 21, 1874. Holland says "The female very closely resembles the female of artonis, and in fact I am unable to distinguish the types of the two species by any marks which seem to be satisfactory." Var. bischoffi, Bischoff's Fritillary, is like the type, but the upper side is heavily obscured by black, concealing the basal wing markings. The female has the spots within the lunules pale and almost white. It is a boreal form. Taken by Cooley. Three specimens, one from Shields river, 6,700 feet, two from Gallatin county, one at 8,300 and one at 9,400 feet. Var. artonis, the Artonis Fritillary, may be distinguished "by the entire absence of silvery scales upon the under side of the hind wings, and also by the fact that the silver spots on the under side of the hind wings are not compressed and elongated as much as eurynome, and by the further fact that all the dark marginal markings of the under side are obliterated. In the female the dark markings underneath are heavier. It has been found in Colorado, Nevada, Utah and Arizona. We have one specimen from the Yellowstone Park. 66 BULLETIN UNIVERSITY OF MONTANA.

Here a lover of groves and forests must be content with a variety of trees that might easily be enumerated on his ten fingers, and but few of even these. Cottonwoods, broken and scrawny, are the only trees of large size near the city, but as one penetrates the country to the heads of the Yellowstone's many tributaries, he meets with ash, elm, box-elder and willows, all native varieties, and differing somewhat from the same trees of the eastern states. In the badlands and in the hilly sections are pines and cedars also, but the majority of our country is a vast prairie, grass clothed, but bare of tree or shrub (the ever-present sage-brush excepted) and parched by the sun from July until winter. What limited amount of shrubbery does occur is also confined to the water-courses. We have our native choke-cherry, wild rose, plum, willow, snowberry, buffaloberry, greasewood and sagebrush, a meagre list in- deed, when compared to the hundreds of shrubs and brushes abounding in most eastern localities. All vegetation without it may be grasses, and wild flowers occur with us, but in the most limited variety. We have no woods, no swamps, no hedges. What wonder then that the entomologist's hopes are saddened as he realizes that a corresponding dearth exists among his favored and busy tribes. I wonder who can recount the exact number of Papilios he has seen during three years past? It is my good (?) fortune to have seen just fourteen during that period. In the season of 1891 I saw but one, it was one of the Turnus group, probably rutulus or daunus, its rapid flight however, baffled detection. In May of this year while returning from our ranch, on horseback, a distance of about one hundred miles, I saw another of this same group, but was unable to capture it. During this trip, also, I counted nine zolicoan, only one of which was not in rapid flight across country; this one, a female, was depositing her eggs on our native wild parsnips, and I caught her easily, and obtained some twenty eggs, which I reared on cultivated parsnips in my garden. The only other Papilio seen this year was one related to zolicaon, but had none of the prominent show of yellow so characteristic of that species when on the wing. What it may have been I cannot say. Finally, two specimens of zolicaon taken on the summit of Signal Butte, near this city, on May 30, 1892, complete the number. I cite my experience with the Papilios to give a general idea of the scarcity of species occurring here. BUTTERFLIES OF MONTANA. 67 A few species of Colias, Pieris, Euptoieta, Phyciodes, and Lycaena occur here, however in sufficient abundance not to be called rare. There exists an unusually localized distribution among most species here, which doubtless results from a similar localization of the foodplants, many of which are to be found only near flowing springs or other sources of moisture. The Satyrids, Pamphila, and other prairie varieties, how- ever, may be met with in country of almost any character, as also may such species as the Argynnids, Pyrameis cardui or Danias archippus. This season has proven an unusually productive one, and fully twice the number of butterflies were on the wing this year than appeared in either 1891 or 1892. Our climate and soil are so dry that no agriculture is successful without irrigation, and I attribute this season's productiveness in the Lepidoptera of this immediate vicinity to systems of artificial irrigation, which has been successfully operated here only the last two seasons, and no doubt all insect life so dependent upon vegetation, will steadily increase as the amount and variety of plant-life is multiplied year by year by the introduction of agriculture under our irrigation systems along the Tongue and Yellowstone River bottoms. In the interest of the readers of the Entomologist News I append a list of the species of diurnals that I have taken about Miles City during a three years' residence here: Papilio zolicaon, rare.

Egg — The eggs are subconical, almost twice as high as wide, truncated at the top, and marked with thirteen or fourteen raised longitudinal ridges connected by a multi- tude of small cross ridges. Larva — Smaller and not as dark in color as the larva of Argynnis. They feed upon violets. Chrysalis — It is pendant, about six-tenths of an inch long, and having two rows of sharp conical tubercles on the back. GENUS BRENTHIS. Key to Species. 1. Basal part of wings not differing from the rest, 2. Basal part of wings black, 3. 2. Under side of wings with silver spots; ocellus at base of hind wings myrina 3. Under side of wings without silver spots and ocellus; a purplish ferrugenous color at the apex, bellona. Cinnamon brown at the apex of fore wings; hind wing crossed by a yellow band formed of star-like spots; black ocellus at base of wings, helena. THE SILVER BORDERED FRITILLARY. Brenthis myrina, Cramer. Figs. 55, 56. Butterfly — The upper side of the wings is fulvous; the black mark- ings are light; the borders heavy. The fore wings on the under side are yellowish fulvous, ferruginous at the tip, with the marginal spots lightly silvered. The hind wings are ferruginous, mottled with buff. The spots are small and well silvered. Expanse male, 1.40 inches; female, 1.70 inches, 43 mm. Egg — The egg is conoidal, about one-third higher than wide, marked by seventeen vertical ribs, between which are a number of delicate cross ribs. It is pale greenish yellow in color. Caterpillar — In its final stage it is about seven-eighths of an inch long, dark olive brown, marked with green; the segments being adorned with fleshy tubercles armed with needle-shaped projections. Chrysalis — It is brownish yellow, spotted with dark brown spots, those of the thoracic and first and second abdominal segments having the luster of mother of pearl. Distribution — It has a wide range, extending from New England to 70 BULLETIN UNIVERSITY OF MONTANA. Montana, from Nova Scotia to Alaska, and southward along the ridges of the Alleghanies into Virginia and the mountains of North Carolina. It has been taken rather abundantly at Crow Creek, Flathead Indian Reservation; at Missoula; at Rimini, 5,500 feet, near Helena, by Brandegee. Taken by Barnes at Aldridge. One day in July, while camped at Crow Creek along the main wagon road between Selish and Poison Brenthis myrina was found abundantly in the grassy creek bottoms. Almost invariably they were taken on the large blue Erigeron macranthus, common in the western part of the state. The afternoon was warm, and was spent almost entirely in butter- fly collecting. Nearly all the specimens taken were of this species. Figs. 55 and 56. Brenthis myrina, upper and lower surfaces August 8, 1904, an afternoon was spent at the upper end of Swan Lake after insects. Brenthis myrina was the only common species, rest- ing occasionally on the blue Erigeron or white Achillea. Several dozen were secured, the return to camp revealing two deer in the marsh. One morning during the last week in August, 1903, as I was wading through the tall wet grass, at the upper end of Swan Lake, just after sun- rise, a butterfly was rather abundant above the tops of the grass. The dew was wet and heavy, and no net was at hand. Batting down an insect with my old hat it proved to be of this species. It may be called common west of the range. THE MEADOW FRITILLARY. Brenthis bellona, Fabricius. Fig. 57. Fig. 57. Brenthis bellona. Butterfly — Pale fulvous on the upper side, with the dark markings on the inner half of the wing narrow, but more or less confluent. The BUTTERFLIES OF MONTANA. 71 dark markings on the outer margin are slighter. On the under side the fore wings are pale fulvous, spotted with purple at the tip and outer margin. The hind wings below are ferruginous, mottled with purple. Expanse, 1.65-1.80 inches, 41-46 mm. Early Stages — Similar to that of B. myrina, but the caterpillar in its mature form differs in not having the spines on the second segment of the body lengthened as in that species. Chrysalis, bluish gray in color, marked with dark spots. Distribution — The butterfly is very common in the whole of the northern United States, as far south as Virginia. It occurs throughout Quebec, Ontario, and British America, as far west as the foothills of the Rocky Mountains. In the state taken by Elrod at ivlissoula and at Swan Lake; by Brandegee at Rimini, near Helena. THE HELENA FRITILLARY. Brenthis Helena, Edwards, Fig. 58. Fig. 58. Brenthis Helena. Butterfly — The wings on the upper side are fulvous, greatly obscured by brown at the base of the fore wings and along the inner margin of the hind wings. The usual markings are light, and the marginal border is also not so heavily marked as in B. myrina. The fore wings on the under side are pale fulvous laved with ferruginous at the tip. The hind wing brightly ferruginous, with small yellow marginal spots and paler spots inclining to buff on the costal border and at the end of the cell, about the region of the median nervules. The female is very much like the male on the upper side, but the ground color is paler. On the under side the markings are more con- spicuous. Expanse, 1.40 inches, 35 mm. Early Stages — Unknown. Distribution— Helena appears to be a common species in Colorado, Montana and New Mexico. It is subject to considerable variation, both 72 BULLETIN UNIVERSITY OF MONTANA. in the intensity of the coloring of the under side of the wings and in the distinctness of the maculation. The collection contains two from Missoula and three from Flathead Lake. Cooley has specimens from near Bozeman June 27, 1900, at 6,800 feet, and July 12, 1900, at 8,000 feet. THE CHECKER-SPOTS.

Lemonias taylori, Edwards. Fig. 58. Fig. 58. Lemonias taylori. Butterfly — Expanse of male, 1.25 to 1.50 inches, 32-38 mm.; female, 1.50 to 1.75 inches, 38-45 mm. Ground color black above; a row of small marginal brick-red spots, largest at the apex; two rows of small light yellow or almost quite white spots across fore and hind wings, the outer row on fore wings sometimes reduced to mere specks; on the hind wing there is usually a row of brick-red spots between the rows of yellow spots; within these rows there are about three or four basal yellow spots no larger than the largest spots in the rows; the cell of the fore wings has a small basal yellow spot, then a larger red bar sometimes broken, followed by three yellow dashes making a bar, a large yellow spot, about the middle of the wing below the cell; costa of fore wings brick red, heaviest at the base; the under side is brick-red, the spots above re- peated and much larger; on the fore wings the yellow spots are washed over by red, and almost lacking on hinder part of wing; legs, palpi, sides of abdomen brick-red; under side of abdomen same color as yellow spots. Early Stages — The food is said to be the ribwort plantain (Plantago lanceolata Linn.) Distribution — It is reported from Vancouver's Island. Prof. Cooley has one specimen from Cascade, on the Missouri river, one from Gallatin County, and one from Missoula; Barnes has several from Aldridge. BRUCE'S CHECKER-SPOT, Lemonias brucei, Edwards. Butterfly— Male: Expands from 1.5 to 1.7 inch 38 to 40 mm. Upper side brown-black, marked with spots of red and yellow in transverse bands; there are three well-marked varieties, in one of which red pre- 74 BULLETIN UNIVERSITY OP MONTANA. dominates, sometimes almost to the exclusion of yellow; in another red and yellow, much as in other allied species; on the third much yellow, very little red; so that the black surface is more exposed than in many species. 1. The red form. The spots dull; the common marginal row wholly red, the submarginal row sometimes red on primaries, sometimes red partly replaced by yellow, and secondaries always red and yellow; the the third row is red and yellow on primaries, red on secondaries, the fourth row just the reverse of this; at end of cell on primaries a short red and yellow band, in the cell four spots, red and yellow alternately, from the arc, the yellow ones very small; on secondaries, a red stripe along upper side of cell, two small yellow spots in cell; fringes black at ends of the nervules, yellow in the interspaces. 2. The spots of the second row red and yellow on primaries, yellow on secondaries; the two next costa sometimes red on the posterior side; the yellow spots in cell of primaries large, and a large yellow patch below cell. 3. Nearly all spots yellow; the marginal red; no other red on second- aries, or a mere trace of it indicating the spots of the third row, which are otherwise suppressed; the submarginal row of primaries represented by a few scales only, as are also the spots in cell. On the under side all three forms agree; primaries dull red, almost without black; the marginal spots a deeper red, the next two rows yellow, the submarginr.1 obsolete on lower half; a yellow p^tcli subapical on costa, another outside arc of cell ;the two cellular spots yellow, dusted red. Secondaries have all the spots clearly defined; the marginal row red, the second row of yellow lunules; the third wholly red; the fourth yellow, the spots of upper half elongated and cut unequally by a black line from costa to lower discoidal nervule; beyond to base red, with a straight row of four confluent spots from costa to sumedian, and a fifth at end of cell. Female — Expands 1.7 to 1.8 inch, 40 to 42 mm. Varies as the male, but some examples still more widely, the yellow spots being very large. On the under side as in the male, except that some examples have the red submarginal spots of secondaries slightly edged with yellow; in the more yellow upper side examples the yellow edging to these spots is broader, and even sometimes extends along the marginal side. This small Melitaea has long been known in collections, but till re- cently I myself have seen few of them, and knew nothing of its localities or habits. Mr. Bruce, who took great numbers of examples, says: "I found it only on high mountain tops (in Colorado) ; this was strictly the rule. These tops are in most cases extensive plains covered with flow- ers, chiefly yellow compositae, and the Melitaeas in question sit on every blossom in numbers, and are very sluggish — or rather I may say, they sit and cling tightly to the flowers to prevent the brisk wind, that is gen- erally blowing at this elevation, from taking them away. I have never seen them down the slope lower than a few hundred yards. It is an abundant species on the Snowy Range at not lower than 12,000 feet, and BUTTERFLIES OF MONTANA. 75 must appear early in June, as many of my specimens taken early in July are rather worse for wear." The species comes also from Montana, Washington Ter., and British America, in the Rocky Mountains. (The above is the original descrip- tion in Can. Ent.) THE ACASTUS CHECKER-SPOT. Lemonias acastus, Edwards. Butterfly — Expanse, 1.50 to 1.60 inches, 38-41 mm. Prevalently ful- vous upon the upper side, and on the under side of the hind wings heavily and somewhat regularly banded with yellowish-white spots, possessing some pearly lustre. Early Stages — Unknown Distribution — Nevada, Utah, Montana. We have not taken it. HOFFMANN'S CHECKER-SPOT. Lemonias hoffmanni, Behr. Butterfly — Expanse, 1.35 to 1.45 inches, 35 to 37 mm. General style of marking similar to L. whitneyi, but with the basal area black, and the black markings toward the outer margin not so heavy, giving it here a more fulvous appearance. Under side much as in whitneyi, but the yellow markings are more prominent. Subject to much variation. Early Stages — Unknown. Distribution — Found in California, Oregon, Nevada, Colorado, Mon- tana. We have not taken it. THE LEANIRA CHECKER-SPOT. Lemonias learnira, Boisduval. Butterfly — Expanse, 1.50 to 1.75 inches, 38 to 45 mm. Ground color brownish-black, fulvous on the costa, with submerged median, and basal rows of yellow spots. Both the primaries and secondaries have a mar- ginal row of red spots, and the former have in addition a sub-marginal row of such spots. The under side of the primaries is reddish fulvous, with the markings of the upper side reproduced. The secondaries have a marginal row of crescents, then a black band inclosing yellow spots, then a median band of long yellow crescents. The remainder of the wing to its insertion is black, spotted with yellow. Early Stages — Unknown. Distribution — Colifornia, Arizona, Nevada, Montana, British America. We have not taken it, nor is it in any of the collections. THE CLOUDED CHECKER-SPOT. Lemonias nubigena Behr. Fig. 60. Butterfly — Expanse, 1.20-1.50 inches, 30-38 mm. Small, characterized jy the red ground color of the upper side of the wings. The species is susceptible of great variations. The markings are quite similar to those of other species, but the size is small. In the variety Wheeled the black ground-color is greatly reduced and almost wholly obliterated on parts of the primaries. Distribution — Found in Nevada. Collected by Cooley at Bozeman 76 BULLETIN UNIVERSITY OF MONTANA. Fig. 60. Lemonias nubigena, from Colorado. WHITNEY'S CHECKER-SPOT. Lemonias whitneyi, Behr. Figs. 61 and 62. Fig. 62. Lemonias whitneyi, Fig. 61. Lemonias whitneyi. under side- Butterfly — Fulvous upon the upper side. Prominent yellow bands on under side of hind wings. The yellow is more prominent in the male than in the female. Expanse male, 1.50 inches, 38 mm.; female 1.70 inches, 44 mm. Early Stages — Altogether unknown. Distribution — It ranges from California into Nevada, north to Mon- tana. Taken at Sinyaleamin lake in the Mission Mountains by Elrod; near Helena by Brandegee; in Bridger canyon and Gallatin county, elevation 7,500 feet by Cooley; Miles City by Wiley. COOPER'S CHECKER-SPOT, Lemonias cooperi Behr. Butterfly and Early Stages — This species is very similar to chalcedon, but the want of the yellowish halo around the lunulae of the brown band on the under side, is a very positive diagnostic character. The brown color of the bands also is always of the same somber hue as that of the under side of the fore wings, and never of the fiery brick red that colors this fascia on the under side of chalcedon, forming a perceptible contrast to the somber coloring of the under slds of the fore wings, which is the BUTTERFLIES OF MONTANA. 77 same in chalcedon and cooperi. With all these well marked differences, the two species look so much alike, that it would have been a long time before cooperi would have been recognized as a distinct species, if it had not been for the striking difference of its caterpillar, which was discovered by Mr. Lorquin near Clear Lake on a species of Scrophularia. This cater- pillar is much more elongated than that of chalcedon. It is nearly of the shape and coloration of that of the European artemis, brimstone yel- low, with a dorsal and a lateral black stripe. We were quite justified in expecting from such a caterpillar something strikingly different from the very common type of chalcedon. But to our surprise our chrysalids gave us a series of crippled butterflies, which could scarcely be distinguished from chalcedon. Since that time I have received a well developed speci- men through the kindness of Baron Koels, wno caught it with several other insects on an excursion to Mount Tamal Pais. It is pretty certain that cooperi will be found in many other localities, as it is only its similarity to our most common vernal butterfly, the chalcedon, that makes it escape our attention." (The above was kindly copied by M. E. Hyde, Asst. Sec. Calif. Acad. Sci., from Behr's original description as given in the Proceedings for 1863-68, Vol. 3, p. 90.) Distribution — Found in Washington, Vancouver's Island, and the Big Horn Mountains, Montana. 78 BULLETIN UNIVERSITY OF MONTANA. THE CRESCENT SPOTS. Genus PHYCIODES, Doubleday. Fig. 63. Butterfly — Generally quite small. Their wings on the upper side are fulvous, or brown, with black margins, spots and lines, and with the under side of the wings reproducing the spots of the upper side. Of the spots of the under side of the wings one of the most characteristic is the pale crescent situated on the outer margin of the hind wings. In the neuration of the wings these butterflies are much like Lemonias. Eggs — The eggs are always higher than broad, having a thimble-like appearance. Caterpillar — The caterpillar is cylindrical, marked with longitudinal stripes, and adorned with tubercles. They do not so far as known weave webs. Chrysalis— It is pendant, with the head slightly bifid. The color is generally some shade of pale gray, spotted with black or brown. They are found in South and Central America, the United States and Canada. GENUS PHYCIODES. Key to Species. Broad central band of white or light buff on under side 2.

Phyciodes tharos, Drury. Fig. 64. Fig. 64. Phyciodes tharos, slightly reduced. Butterfly — Expanse, male, 1.25 inches, 32 mm.; female, 1.65 inches, 41 mm. Upper surface reddish fulvous marked with black; two rows of more or less coalescing circles near the base of the wing, the first of two circles, the second of four, and an ellipsoid at the end of the cell; a patch of black beyond the cell on the costa and one on the hind margin, sometimes the two being connected by a dentate line. The outer border is broad, black, and through it runs a crenated line' with a yellowish or fulvous lunule in the middle, in some examples distinct, in others con- nected with the central color; black dot near the posterior angle. Hind wings similar to front wings, the median black band narrower; both light bands are fulvous, and the outer contains a row of black spots. The under side of fore wings yellowish fulvous, with yellow spots and four black patches, two on the costa before the apex, one at the posterior angle, and one on the hind margin. The under side of hind wings pale buff washed with umber-brown, the basal half with more or less complete bands of pale spots edged with brown; the row of black spots same as above; a sub-marginal row of lunules, the middle large, silvery, the others more or less obscure. The terminal, costal, and middle brown patches are present in some examples, the wing being well suffused with brown. Early Stages — The egg is light greenish yellow. The caterpillar, which feeds upon various species of aster and allied compositae, is dark brown after the third moult, its back dotted with yellowish and adorned with short black bristly spines, which are yellow at the base. The chrysalis is grayish white, mottled with dark spots and lines. Distribution — This is one of the many dimorphic species. It ranges from southern Labrador to Florida, in fact all over North America, north of Texas and south of the region of Hudson Bay, except the Pacific coast of California. Found in Montana at Missoula, Fish Creek, Ruby Mountain, Crow Creek. Brandegee has it in his collection from Gold Creek. Wiley collected it at Miles City. It is abundant around the Biological laboratory at Bigfork. It is abundant in the Bear Paw Mountains, according to Coubeaux. Dr. Elliott Coues collected it at Milk River July 25, 1874, called by Edwards Marcia, now recognized as a synonym for tharos. 80 BULLETIN UNIVERSITY OF MONTANA. THE CARLOTA CRESCENT. Phyciodes carlota Reakirt. Fig. 65. Fig. G5. Phyciodes carlota. Butterfly — Upper surface black; some fulvous spots near the base of the fore wings; a fulvous band through the middle crossed by the black veins; a sub-terminal row of whitish dots in the broad black terminal border; and a white lunule in the middle of the border near the edge of the wing. In the females there are traces of other white lunules just within the margin. The hind wings similarly marked, except that there is a row of black sub-marginal spots circled with fulvous, and the lunules are faint in the males. Under side of fore wings fulvous, with three or four not very prom- inent bars in the cell, a somewhat triangular patch beyond, and a term- inal brown black border with the sub-terminal row of spots, between median venules one and two there is a large conical whitish spot, the base on the double terminal line; this double line running in zigzag to the apex, and the inner points silvered more broadly towards the apex, and the inner point sending a white ray to the margin. The same is re- peated towards the posterior angle, but with less silver. The hind wings dark brown washed with whitish, more towards the base, only two yellowish spots in the cell. Near the base is a broken silvery band, and through the middle a silver band crossed by the brown veins, the outer margin dentate. The sub-marginal row of black spots pupilled with white. The margin is similar to that of the fore wings, save that the large spot is silvery instead of whitish. Distribution — It is found in the southern and western states, Rocky mountains, Montana to Arizona. Wiley has many specimens in his col- lection from Miles City and Sandstone. He bred specimens in 1890. It is not reported by the other collectors. THE MYLITTA CRESCENT, Phyciodes Mylitta, Edwards. Butterfly — Expanse of male, 1.15 inches, female larger. Broadly bright fulvous on the upper side, the dark markings slight; a narrow band of dark on outer edge of both pairs of wings, then a sub-marginal row of crescents, bordered with black; hind wings with a row of small black spots, a black spot on anterior edge and dark base; fore wings crossed by BUTTERFLIES OF MONTANA. 81 two series of black markings like bands, in addition to the preceding; bases dark. Under side fulvous, fore wings with some black at posterior angle; behind this or hind wing, a large light patch; a light patch bor- dered with dark at middle of outer edge; many light spots on hind wing, making at least two rows. Early Stages — The food plant is the thistle. The caterpillar is black, yellowish below, with a faint twinned yellow dorsal line and faint lines of the same color on the sides. The spines, which are arranged in six rows, are black. Those of segments four, five, and six, yellow. The chrysalis is dull wood-brown. Distribution — Washington to Arizona, eastward to Colorado. In the state taken at Helena, July ,2 '03 (1), at Flathead lake, July, '04 (1), and in Yellowstone Park (1). Allen has collected it at Dillon. THE MEADOW CRESCENT SPOT. Phyciodes pratensis Behr.

BUTTERf "LIES OF MONTANA. 83 A Chrysalis. My little Maedchen found one day A curious something in her play, That was not fruit, nor flower, nor seed; It was not anything that grew, Or crept, or climbed, or swam, or flew; Had neither legs nor wings, indeed; And yet she was not sure, she said, Whether it was alive or dead. She brought it in her tiny hand To see if I would understand, And wondered when I made reply, "You've found a baby butterfly." "A butterfly is not like this," With doubtful look she answered me. So then I told her what would be Some day within the chrysalis: How, slowly, in the dull brown thing Now still as death, a spotted wing, And then another, would unfold, Till from the empty shell would fly A pretty creature, by and by, All radiant in blue and gold. "And will it, truly?" questioned she — Her laughing lips and eager eyes All in a sparkle of surprise — "And shall your little Maedchen see?" "She shall!" I said. How could I tell That ere the worm within its shell Its gauzy, splendid wings had spread, My little Maedchen would be dead? Today the butterfly has flown — She was not here to see it fly, — And sorrowing I wonder why The empty shell is mine alone. Pernaps the secret lies in this: I too had found a cnrysalis, And death that robbed me of delight Was but the radiant creature's flight! —MARY EMILY BRADLEY. S4 BULLETIN UNIVERSITY OF MONTANA. GENUS POLYGONIA, HUBNER. The Angle-Wings. Fig. 67. Butterfly — Medium sized or small, characterized by the more or less deeply excavated inner and outer margins of the fore wings, the tail-like projection of the hind wings at the extremity of the third median nervule, the closed cell of the fore wings, and the thick covering of scales on the upper side of the palpi, while on the sides and tops of the palpi there are but few scales. They are tawny on the upper side, spotted and bordered with black; on the under side mimicking the bark of trees and dead leaves, often with a C-shaped silvery spot on the hind wings. The insects hibernate in the butterfly form in hollow trees, under bark and leaves, and like places. Early Stages — The eggs taller than broad, tapering upward from the base. The sides are ribbed. They are laid in clusters or in a short string-like series. The caterpillar is cylindrical, adorned with rows of branching spines. They feed upon the nettle, elm, hopvine, and other plants Fig. 67.

Under side very dark, paler irrorations silenus. THE FAUN. Polygonia faunus Edwards. Fig. 68. Fig. 68. Polygonia faunus. Butterfly — Upper surface fulvous, dark, the hind wings darker. Next the apex of the fore wings, the base of both wings, and the inner margin of hind wings dusky. Border of wings broad and dark brown or black, in the fore wings dentate at the apex, and bordered within by a series of sub-obsolete tawny lunules. There are two spots and a bar in the cell, and a bar at the end, but there are only three round spots between the cell and the posterior angle, the lowest supplemented by a shade above it. The spots are very dark or black. Hind wings with dark ferruginous next the border, shading toward the middle, a series of paler spots next the border and an irregular roof of black spots across the middle. Under side of both wings dark brown on the base, with an irregular common blackish band across the middle, darkest on its outer edge and within the abdominal margin, where its outline is obliquely serrated. Beyond this band the color is pale brown mottled with grayish white, which is clearest on the fore wings. The whole surface is clouded with vinous, and more or less crossed by fine abbreviated streaks of brown. Apex of fore wings yellow-brown, with three small lanceolate ferrugin- ous spots, the lower enclosing a blue or green point. The outer margin of both wings, below these, is bordered by a series of confluent blue-black, sometimes olive-green spots following the outline of the wing. Within these is another series of rounded spots of the same color. On the disk of the hind wings is a white G varying in form. Early Stages — The mature larva is one and a quarter inches long; 86 BULLETIN UNIVERSITY OF MONTANA. head black, with two branching horns and a few scattered white hairs. Upper side of joints 2 to 6 brick-red, stripped transversely with blue, yellow and black, a few white hairs on joint 2. There are four branching yellow spines, with black tips, on joints 3 and 4, and six on joints 5 and 6. Joints 7 to 12 are white, with a faintly marked black stripe along the back, each joint with three transverse yellow bands and two oblique black spots. These joints have each seven spines, all white except the one next the lowest, which is brown. Last two joints black, with seven and four Opines respectively. Sides red, with two black bands, the lowest spotted with blue. The chrysalis is grayish brown Head with two bi-forked horns, the outer point very short; thorax with an elevated keel-like ridge on top, with a small tubercle on each side The food plants are gooseberry, currant, willow and birch. Distribution — It is found from New England south to the Carolinas and west to the Pacific. The collection at the University embraces specimens from Missoula, Sinyaleamin Lake, Flathead Lake, Swan Lake (many). At Swan lake, August 20, 1903, faunus was abnudant at Bond's cabin, but was very hard to take. It was flying about the lake shore and around the cabins of Bond and Groom, forest rangers, in common with Vanessa J. album, Vanessa californica Polygonia satyrus and P. zephryus. Although quite abundant comparatively few were taken. Brandegee has taken it at Helena. Fig. 69. Polygonia faunus on the left, black satyrus in the middle, zephyrus on the right, under side of wings. THE SATYR. Polygonia satyrus, Edwards. Fig. 69. Butterfly — Expanse 1.75 to 2.00 inches, 45-51 mm. Tawny or fulvous above. Wings with dark brown, almost black border. A row of lunules of lighter color than ground work within the black border. General color much lighter than faunus. Inside of the lunules is a wash of reddish brown, almost making a line across both wings, more conspicuous on BUTTERFLIES OP MONTANA. 87 hind wings. Bases of wings brownish black Under side of wings dark, with light mottlings and marblings. Apex of fore wings lighter. The light markings make a band across the wings, the inner margin of which crosses the middle of the wings. A light patch usually on costa of fore wings, between light band and base. Wings deeply excised. Legs and feet light colored. Antennae ribbed below, with black clubs, the ends of which are of the same color as the upper surface of wings. There are two forms. One is very dark below, almost black, with a. white open C like in faunus. The other is much lighter below, the color being a dark brown, the spot on hind wings forming a G, larger. The under surface is broken by darker brown patches extending crosswise of the wings. Above the wings are lighter and the black spots much smaller. Early Stages — The caterpillar feeds on the nettle. Distribution — From Ontario to the Western part of the United States, It has been collected in the state by Elrod at Missoula, at Sinyaleamin and Swan lakes; by Cooley at Bozeman, September, 1899; by Brandegee at Helena. THE ZEPHYR Polygonia zephyrus, Edwards. Fig. 70. Fig. 70. Polygonia zephyrus. Butterfly — Upper side of wings similar to faunus and satyrus, ful- vous, marked with yellowish toward the outer margins, the dark mark- ings upon which are not as heavy as in the other species. Below the wings are much paler than in faunus or satyrus, reddish brown,, marbled with darker brown lines; the band across the wings is quite light, the female with a row of small light yellowish spots pupiled with black. Distribution — Rocky Mountain region from Colorado to California, and from Oregon to New Mexico (Holland). Taken in Montana by Cooley 88 BULLETIN UNIVERSITY OF MONTANA. at Bozeman, by Wiley at Miles City, Brandegee at Helena, and by Elrod at Missoula. One worn specimen from Bear Paw Mountains belongs to this species. THE GRACEFUL ANGLE-WING. Polygonia gracilis, Grote and Robinson. Butterfly — A small species, rather heavily marked with dark or blackish on the upper side. The wings on the under side are very dark, crossed about the middle by a pale gray or white band, shading off to- ward the outer margins. This light band serves as a means of easily identifying the species. Expanse, 1.75 inches, 45 mm. Early Stages — Unknown. Distribution — The species has been found on White Mountains in New Hampshire, in Maine, Canada and British America, as far west as Alaska. While the species is recorded as having a western distribution it has not been taken by the writers in the state, nor is it reported in the other collections. THE SILENUS ANGLE-WING. Polygonia oreas. var. silenus, Edwards. Butterfly — Expanse, 2.2 inches, 56 mm. Primaries moderately in- cised; slightly dentated; tail long, broad and straight; a prominent dentation between tail and inner angle, which last is much pronounced. Upper side deep red-fulvous, clouded with brown-ferruginous next base of each wing and on disks, and spotted with black, hind margins have a broad cinnamon border of nearly uniform width, black with a ferrugin- ous tint; on the inner side a series of separate, pale fulvous spots, yel- lowish next apex of primaries, irregular in size, lanseolete; primaries have a large sub-apical ferruginous patch on costal margin, another near inner angle, a broad black spot from costa covering the arc, two oval spot in cell placed transversely and sometimes confluent, two others in first and second median spaces, and a large sub-ovate spot on sub- median interspace extending partly over the one next above. Secondaries have the entire costal margin brownish-black, a large irregular black patch on disk between upper branch of the sub-costal and the median nervure; a brownish-ferruginous patch at base of the upper median nervules; the whole extra-discal area suffused with ferruginous, passing imperceptibly into the marginal border; fringes fuscous, with a very little white in the emarginations. Under side mostly in shades of black or black-brown, the entire sur- face, except where deep black prevails, covered with fine abbreviated streaks darker than the ground; apex of the primaries faintly tinted with olivaceous; costal mragin brown, with a few gray scales near apex, a whitish patch beyond extremity of cell and a smaller one nearer base; base of primaries brown, of secondaries brown next costa, black towards abdominal margin; the disks crossed by a common, broad, black band, very irregular in its exterior outline, on lower part of secondaries merg- ing into the black basal area, outside the band, on primaries and upper part of secondaries, grayish-white for a little space, densely streaked, BUTTERFLIES OF MONTANA. 89 and beyond to margin blackish -brown; the extra-discal points nearly or quite lost on the dark ground; sub-marginal crescents black, obsolescent, often wanting altogether; in the cell of primaries three elongated, narrow, deep black spots, two of which lie along the costal nervure, sep- arated by a very small interval, and each edged by a velvety black line; the third along median nervure, illy defined without such edging; the spot on disk of secondaries dead white, bent at right angles; the lower limb straight, thick abruptly sloping to a point by the cutting away of its upper side; the upper branch narrower, slightly curved, nearly as wide at top as elsewhere and ending bluntly; fringes with the white area more extended than on upper side.

Female expands from 2.1 to 2 3 inches. In shape very like the male; upper side dull yellow-fulvous, the spots large; under side more brown than black, the extra-discal area to margin pretty uniform in shade, the ground being dark gray, nearly lost in the denseness of the brown streaks; sub-marginal points and crescents obsolescent; silver mark of same shape as in the male, often quite as heavy. Early Stages — Larva unknown. Distribution — Found in California, Washington, Vancouver Island, and Montana. We have not taken it. 90 BULLETIN UNIVERSITY OF MONTANA. THE TORTISE SHELLS. Genus Eugonia Hubner. Fig. 71. Butterfly — Medium sized insects, wings above generally some shade of black or brown, marked with red, yellow or orange. The head is moderately large, eyes hairy, palpi more or less scaled, prothoracic legs feeble and hairy. The cut shows the wing venation. The cell of the primaries may or many not be closed. The cell of the second- aries is open. The fore wings have the outer margins more or less deeply excavated between the extremities of the upper radial and the first median veins, at which points the wings are rather strongly produced The hind wings have the outer margin denticulate, strongly produced at the extremity of the third median nervule. Early Stages — The eggs are short, ovoid, broader at the base, ridged at the summit. They are generally laid in large clusters upon the twigs of the food plant. The mature caterpillar is cylindrical, adorned with long, branching spines in longitudinal rows. It feeds upon the elm, willow, and poplar. The insects hiber- nate in the imago form, and are among the first to appear in the spring. THE COMPTON TORTISE. Eugonia j. album, Boisduval Leconte. Fig. 72. 71. Venation of Eugonia J. album. Fig. 72. Eugonia j. album. Butterfly — Expanse of wings, 2.50 to 2.75 in., 64 to 70 mm. Upper sur- face dull yellowish, dusky at base, washed more or less with rusty brown, especially on the basal half. Outer border of fore wings dull black with a double crenate line and two more or less large costal bars — one at the end of the cell, and the other between the cell and a white sub-apical BUTTERFLIES OF MONTANA. 91 patch; a black spot in the cell with three black spots below the cell, the one nearest the base of the wing quite large. The hind wings have a black and brown border a little within the margin, the yellow outside sprinkled with brown atoms; a large black space below the costa, beyond which is a whitish patch. Under side grayish brown, the usual darker band across the middle which on the hind wings is but little darker than the base; beyond this greenish white the whole surface finely reticulated with brown lines. There are the usual three elongate patches edged with dark brown in the cell of the fore wings. The submarginal row of ashy-blue lunules be- tween these and the median band. The lunules do not reach the apex of the fore wings. Early Stages — The mature larva is two inches, 50 mm. long, head with black markings on the sides, thickly set with little points and with short spines; somewhat cordate, the vertices surmounted by two shining black, thick spines, verticeliated near the tip. The dorsal and subdorsal rows of spines shining black except at the base, which is reddish, with long branches, those of the anterior joints more thickly branched than the others. The super- and sub-stigmatted row reddish tipped with black. The chrysallis is one inch long, of a beautiful color, delicately re- ticulated, with six golden spots on the bac't. The food-plant is not known, but Prof. Fernald's surmise is that it may be willow. The butterfly hibernates, the new brood appearing about the middle of August. Distribution — It is a northern form, being found in Pennsylvania upon the summits of the Alleghanies, and thence northward to Labrador on the east and Alaska on the west. It is always a rather scarce insect, says Holland. See note accompanying"' the genus. It is occasionally found at Missoula. Around the biological laboratory at Flathead lake it is often captured. At Schultz's cabin, which is along Aeneas trail over the Swan range, it is quite common, but Bond's cabin at Swan lake is the greatest collecting field in the state, perhaps in the country, for this species. Hundreds were taken here in two or three days in August. 1903. Wiley has one specimen from Miles City, July 15, 1892. 92 BULLETIN UNIVERSITY OF MONTANA. THE CALIFORNIA TORTOISE-SHELL, Eugonia californica, Boisduval. Fig. 73. Fig. 73. Eugonia californica. Butterfly — Similar in general shape and appearance to E. J. album, but easily distinguished by the following peculiarities. Color — Deep fulvous, spotted with black and having a black border. A black bar across the cell. On the underside dark brown, with a light border. The entire surface marked with fine lines. Expanse 2.00-2.25 inches, 51-&7 mm. Early Stages— The caterpillar feeds upon Ceanothus. Distribution — It ranges from Colorado to California and as far north as Oregon, east to Miles City. In 1900 californica was quite common up Hell Gate canyon near Missoula, many having been brought in late in May and early in June. August 20 it was still abundant at Swan Lake, giving evidence of two broods. It is not infrequent about Flathead lake, and evidently covers much unexplored western territory. Wiley reports it at Miles City In 1903 the earliest butterfly at Missoula was a californica taken Febru- ary 19. BUTTERFLIES OF MONTANA. 93 Eugonia J-Album in Western Montana. "This insect is generally rare," writes Holland in his Butterfly Book. In several places in the western part of the state it may be taken in large numbers. At the upper end of Echo Lake, next to the Swan range, we have never failed to take it during our annual pilgramages to the summit of the range, MacDougal mountain. The old submerged cabin in the lake is a safe refuge. The cabin on the bank, now deserted, offers a safe retreat from enemies save the human entomologist, who finds here a great opportunity for capturing a rare specimen. But it is at Swan Lake that Eugonia J. album flourishes in its splen- dor, magnificence and abundance. This beautiful little sheet of water lies cradled between the Swan and Mission ranges. At its upper end, on the eastern shore, are three cabins. The cabins are along the trail which leads up the lake, through the Swan river forest above the lake to the wagon road leading to Ovando, Missoula, and other places. A clearing of a few acres is around the cabins. Dense woods come to the clearings on all sides. In August the sun is intensely hot in the small open patches about the cabins. About these small log huts, seek- ing the shade of the rude porch or the interior of the stable, Eugonia J. album was to be had by the dozens. They would alight on the logs of the buidings, the stumps in the clearing, the fence rails, and the bark of the living trees. After alighting they remained perfectly quiet, so that one could carefully adjust the net over them, and with a quick jerk scoop them into the net. In this way a half dozen were often fluttering in the net at once. It was practically impossible to capture them on the wing, so quickly can they dodge and so swiftly do they fly. When the butterflies alighted on the bark of the fir, cottonwood or birch, upon which they were generally taken, they were almost invisible. It was interesting to see them remain in the same quiet attitude on the top rail of a fence or the skinned log in the cabin, where they were very conspicuous, as on the trunk of a tree where they were invisible. Pro- tective resemblance was in this species beautifully illustrated, and those who made the trip to Swan Lake in August, 1903, will not soon forget how the insects were controlled by instinct. Other insects were out, and were captured. Eugonia californica was much less common than E. J. album, while an occasional Polygonia faunus was picked up. The western admiral was rare. Robberflies were out in abundance, as were also bees. Two species of flies were captured which mimic bees, and a dozen species of butterflies were found in greater or less abundance. Nowhere in Montana have we seen more butterflies at one place or captured more in one day than at Groom's cabin at the upper end of Swan Lake, when the species under discussion was taken in such abundance. In early August, 1904, another visit was made to the cabins at Swan Lake. J. Album was in much less abundance, and difficult to take be- 94 BULLETIN UNIVERSITY OF MONTANA. cause of the great number of baldfaced hornets which seemed to have possession. Not a Polygonia was seen. In 1905 album was carce. Its place was taken by the bald-faced hornet. This latter insect practically prevented butterfly collecting. MOUNTAIN SWARMING OF VANESSA CALIFORNIA. During an ascent of Mount Shasta, made in August, 1889, a most in- teresting occurrence was noted in the flight of countless myriads of but- terflies (Vanessa californica) at an altitude far above snow-line. In our early morning climb of August 29, of the above year, we had left our horses at half past 4 o'clock, at what is known as "Horse Camp," at very near snowline, where there were many small snowfields close about us. Our progress was very slow and tedious, being all of the time over loose, sliding fragmentary rocks, or the almost smooth, hard-frozen surface of the icy snow, and which latter did not soften till long after the sun had swung high enough to shine full upon it. Some little time after daylight, but long before we could see the sun, as he was hidden from us by the high crest of a sharp ridge on the southwest aspect of the mountain (our ascent being made from Sissons, west of the mountain), a few signs of insect life were seen in the shape of "snow-fleas," two or three large- winged grasshoppers, and, occasionally at first, a butterfly. The last two were stiffened by the cold as if they were there from the day previous. The latter insect increased much in numbers as we ascended, and were many of them found in among and under the loose stones as well as a few upon them. At perhaps half past 9 we came to a point upon which the sun had long been shining, and here they were flying in the air, the flight being in a south-easterly direction. From here they seemed to increase very rapidly in numbers up the remainder of the ascent to well toward the summit. The latter was reached at 11:20 A. M.; the temperature was noted at 42 Fah. in the open air. We remained here about a half hour, then passed down by way of the Hot Sulphur Springs, and then out on the southerly face of the mountain. We again encountered our beauti- ful friends at not farther than six or eight hundred feet below the ex- treme peak, and now in countless numbers, filling the air with their flashing wings, and all passing in the same direction as observed during the ascent — towards the southeast. This strange sight continued until we seemed to pass below them, at an altitude of between 11,000 and 12,000 feet. The fact of its being a continuous flight of these insects across the mountain in one direction during the warm part of the day — a period of nearly five hours — is beyond question. That it was in progress one or more days previous to that upon which I observed it is an easy deduc- tion from the fact of the numbers of the insects found among the rocks and stones while yet stiffened by the cold of the night air. How much longer it may have continued I had no means of knowing. Where they could have come from, in such vast numbers, and what brought them to such a high altitude, is of course a matter of pure specu- lation. I had no means of preserving specimens of these insects except to BUTTERFLIES OP MONTANA. 95 place them between the leaves of a notebook; in this way some were kept for identification. A gentleman whom I met a few days later pro- nounced the species to be Vanessa milberti, but after presentation of the account of the flight, with the specimens, before the Biological Society of Washington it was determined for me by Mr. Howard as Vanessa' californica. — C.

It has BUTTERFLIES OP MONTANA. 97 been taken at Missoula, McDonald and Sinyaleamin lakes in the Mission mountains, Flathead lake, and Swan lake. At Missoula antiopa and milberti are the first signs of spring. Branedgee has collected it at Helena, Wiley at Miles City. It is a handsome ornament for a col- lection. Tolerably common in the mountains near Big Sandy. Collected 6y Coues along the 49th parallel in 1874. Stridulation in Euvanessa Antiopa. Althougn the sound made by this butterfly without doubt is the ex- pression of certain emotions, be it of anger or of love, since it is not made by the emissions of the breath, we cannot, I think, consider it more than elementary voice, and in the present instance a singularly erratic development of its elements. It may be that "In Lorranise ther notis be Full swetir than in this contre," for English entomologists are I believe, generally of opinion that the sound which butterflies make is caused by their rubbing their wings to- gether in their ardor. In the Entomologist's Monthly Magazine for Feb- ruary, 1877, page 208, I find the following notice: "In 1872, a female antiopa came into my possession in a hibernating condition, and in that state she would, when disturbed, partially expand her wings, and at the same times was produced a grating sound, which seemed to come from the base of the wings. — A. H. Jones, Shrublands, Eltham." Let anyone now take a dried specimen of this butterfly from the cabinet and grasping the fore wing by its front edge rub it backwards and forwards over the hinder one, so that the bases meet, but being at the same time careful not to crumible the wings and so produce a false sound. We will then without fail hear the sweet secrets of antiopa, which are beautiful and delicate in expression, recalling the trickle of the brooklet. I may notice that Vanessa butterflies are renowned and well-known as stridulators on account of their large size, but that nearly all butter- flies rub their wings together when under the influence of the emotion of love, and since it is the result of friction to produce a striated surface, many of these smaller ones must have organs of sound too fine for human sense. My own researches have always been circumscribed from a want of adequate microscopic power. — A. H. Swinton in Insect Life. MILBERT'S TORTOISE SHELL, Aglais milberti, Godart. Fig. 76. Fig. 7G. Aglais milberti 98 BULLETIN UNIVERSITY OF MONTANA. Butterfly — Expanse of wings 1.6-2.55 in., 40 to 65 mm. Upper surface brownish black, with a broad fulvous band between the middle and outer margin, paler on its inner edge. On the fore wings the pale band con- tains a black patch on the costa, with a white spot on one or both sides. There are two fulvous spots in the cell. The border is composed of two parts, the inner black, the outer a black brown, crenate line on each side of which it is a little paler. The black on the hind wing supports a row of violet lunules. Underside dark brown with the usual wavy lines and spots; the outer half yellowish brown with a submarginal of gray blue lunules which are black edged. Larva — The mature larva is a little more than an inch long, with a black head sprinkled with minute whitish dots, from which spring pale hairs. The body is nearly black above, with small white dots and pale hairs, which give it a grayish color. The spines are arranged as in antiopa, and are black and branching. It has a greenish yellow lateral line above which is a bro"ken line of brighter orange yellow shade. The larvae are found on the wild nettle, and there are two broods in a season. Chrysalis — The chrysalis is .8 of an inch long, 20 mm., slightly angu- lar, the frontal beaks short, conoidal; thoracis projection forming nearly a right angle; dorsal spines but little elevated. Distribution — It ranges from the mountains of West Virginia north- ward to Nova Scotia and Newfoundland, thence westward to the Pacific. This tortoise-shell butterfly is one of the first harbingers of spring. Uusually it is the first butterfly seen about Missoula, where it is rather common. It is usually quite abundant around the biological laboratory at Flathead Lake, but in the summer of 1903 but very few were seen. Brandegee has collected it at Helena, and Wiley reports it rare at Miles City. At Swan Lake it is occasionally seen, probably about the same in numbers as at Flathead Lake, owing to their close proximity. Cou- beaux says it is very abundant all over the country about Big Sandy. Taken by Coues at Chief Mountain, August 22, 1874. THE LADY BUTTERFLIES, Genus Vanessa, Doubleday. Fig. 77. Butterfly — Medium-sized insects; the wings on the upper side are some shade of black or brown, marked with white, red or orange. Head rather large, eyes hairy, palpi more or less heavily scaled. The cut shows the venation of the wings. The outer margin of the wings is dentate. The wings are not angulate, as in vanessa, but are more rounded. The ornamentation of the under side tends to become ocellate, or marked by eye-like spots. Some are ocellate. Egg — This is broadly ovoid, being much like the egg of the genus Vanessa. Caterpillar — In its mature form it is covered with spines. Fig. 77. ~v^iation Chrysalis — It is much like Euvanessa. of vanessa. BUTTERFLIES OF MONTAMA. 99 Genus VANESSA. Key to Species.

Vanessa atalanta, Linnaeus. Fig. 78. Fig. 78. Vanessa atalanta. Butterfly — This butterfly is brown above, with a fulvous band on the outer margin of the hind wings, containing brown spots. The fore wings are also crossed by a fulvous band, which begins at the posterior angle and passes through the cell. There is a white bar beyond the cell, also a marginal row of about five spots, the fourth from the costa being the largest. The spots of the upperside reappear on the underside, but the brown is marbled with gray, blue and green and there is a sub- marginal row of spots oh the hind wings. Expanse 2.00 to 2:25 inches, 51 to 57 mm. Early Stages — The eggs are green, barrel shaped. The young larva is greenish brown, and furnished with ten rows of black curved hairs. In reaching maturity it passes four moults. The mature larva is 1.3 in. long, cylindrical enlarged in the middle and of a velvet black color, sprinkled with fine velvet points. The chrysalis is from .85 to .95 of an inch long, cylindrical. The dorsal tubercles are gilded. The color is usually gray. The food plants are nettle and hop. Distribution — It is found in the United States generally. During the summer of 1903 it was taken sparingly at the Biological Station at Flat- head Lake. It has not been seen at Missoula. It is not in the collec- tions of Wiley, Cooley or Brandegee, and must be very rare in the state. It is reported by Dyar from the Kootenai country. 100 BULLETIN UNIVERSITY OF MONTANA. THE THISTLE BUTTERFLY or THE PAINTED LADY. Vanessa cardui. Linn. Fig. 79. Fig. 79. Vanessa cardui. Butterfly — Pyrameis cardui, or the Painted Lady, has an upper sur- face of fulvous color, the apical portion of the fore wings being black. There is a white bar in the apical black portion of the fore wings and a submarginal row of four white spots; the inner ones being the smaller. The underside of the fore wings is red except the apical part which is marked as above. The hind wings have a submarginal row of five black spots. Both wings have a border, the hind wings having a broken one. The underside of the hind wing is marbled with brown, gray and white. The ocelli contain blue. The inner row of the margin is blue or lilac. Expanse of wing 1.75 to 2.5 inches, 45 to G4 mm. Early Stages — The mature larva is 1.5 in. long, cylindrical, rather robust. The general color is a delicate lilac. Between the joints are two lines of bright yellow. The space between the yellow occupied by two narrow black lines and one white one. There are seven rows of tubercles from which arise branching spines. The head is black, stigmata black with some black spots over the body. Distribution — Most widely distributed of all known butterflies, being found in almost all parts of the temperate regions of the earth and in many tropical lands in both hemispheres. It is double brooded and hiber- nates in the butterfly state. Found all over Europe, North America, in Africa, — save in the dense jungles of the Congo. — in South America, in Australia and in many islands of the sea; at some times scarce and then at seasons it fairly swarms. (Holland.) One of these swarms visited Montana in the spring of 1899. During late May and early June there were hundreds and thousands everywhere in the western part of the state, noted especially at Missoula and Helena. So abundant were they that they were noticed by all, and considerable alarm was felt by some lest there should occur later an outbreak of an insect pest. Happily this did not occur. BUTTERFLIES OF MONTANA. 101 It abounds about the biological laboratory at Flathead lake, and specimens showing great variation have been captured. Brandegee has taken it at Helena and Wiley at Miles City. It is abundant in extreme ends of the state. Cooley reports it abundant at Bozeman. It seems to be everywhere one of the most common insects. It is known among entomologists to be the most widely distributed of all butterflies, so far as present knowledges goes. Its food plants are thistles, (Carduus), Urtica, (nettle), Onicus, (plumed thistle), and Altheca (marsh mallow). Coubeaux calls it abundantly around _.ig Sandy. Collected by Coues along the 4th parrallel in 1874. THE WEST COAST LADY. Vanessa caryae, Hubner. Fig. 80. Fig. 80. Vanessa caryae, 4 upper, 5 lower surface. Butterfly — It is distinguished from P. cardui by absence of the roseate tint peculiar to that species. It has a complete black bar across the cell in the primaries. Expanse 2.00 in. Distribution — It ranges trom Vancouver to Argentina; found as far east as Utah. Two specimens have been taken at Missoula. As it has been taken by no one else Missoula is perhaps as far east as it will be found. HUNTER'S BUTTERFLY, Vanessa huntera, Fabricius. Fig. Vanessa huntera, natural size. 102 BULLETIN UNIVERSITY OF MONTANA. Butterfly — Expanse, 2.00 to 2.25 inches, 50 to 64 mm. Upper surface fulvous ; a little tawny at base, the apical portion of the fore wings black, this continued as a border to the posterior angle. The apical black con- tains an oblique fulvous bar beyond the cell, and the submarginal dots as in atalanta, the first two blended, and one farther down in the fulvous. Besides this there are five triangular black marks, two of which are in the cell. The border of both wings consists of three more or less distinct lines, the inner on the hind wings in the form of a shade. The apical portion of the border on the fore wings is washed with lilac; and there is a gray-blue bar at the anal angle. Hind wings have a submarginal row of five black spots, the second and fifth pupiled with blue. Costa black. The under side of fore wings is red, except the apical portion, which is marked as above. Hind wings marbled with brownish black and white, with two large ocelli. By these it is easily distinguished. The outer border is four black lines, with violet between the two inner. Early Stages — The mature larva is 1.25 inches, 32 mm, long, the body velvety black, between the joints four transverse lines of pale yellow alter- nating with narrow black lines. The food plants are Gnaphalium, Anten- naria, Artemisia, and allied species. Distribution — From Nova Scotia to Mexico. In the state it is report- ed only by Campbell Carrington and William B. Logan, of the Expedition in 1871, locality not given. THE MONARCHS, Genus Basilarchia. Scudder. Butterfly — Head large; the eyes are large and naked; the antennae moderately long, with a distinct club; palpi compact, stout, produced, densely scaled. The fore wings are sub-triangular, apex well rounded, the lower two-thirds of the outer margin slightly excavated. The first two sub-costal nervules arise before the end of the cell. The hind wings are rounded, crenulate. Early Stages — Eggs nearly spherical, the surface pitted with large hexagonal cells. The mature caterpillar is cylindrical, the second seg- ment with two prominent rugose club-shaped tubercles; they are strik- ingly mottled or spotted. Chrysalis suspended by a stout cremaster. They feed upon the leaves of various species of oak, birch, willow, or linden. Three species are found in the state, to be separated from each other by the following key. Key to species. 1.

THE VICEROY, Basilarchia archippus, Cramer. 103 Fig. 81. Basilarchia archippus, From water color drawing by Mrs. Edith Ricker. Butterfly — Upper surface fulvous, the lines black; on the fore wings a dark triangular patch, containing three white spots on the costa beyond the cell, continued to the posterior angle in a narrow line. A black line crosses the hind wings about two-thirds of the distance from the base. Outer border black containing a row of white spots, and there are two ante-apical white spots; the lower one quite small. Underside similar to upper, paler fulvous. The fringes are black, spotted with white. Earley Stages — The larva feeds upon willow, popular, balm of gilead, aspen, and cottonwood. It is two or three brooded. Distribution — Found over nearly the whole of the United States as far west as the Sierra Nevada Mountains, and has been found sparingly even to the Pacific coast, near our northern boundaries. B. archippus is injurious to the oak and to the wild plum. This species mimics the Monarch butterfly Anosia plexippus, so abundant in the eastern states. The Monarch is sparingly found in the western part, rather abundant east. The eastern milkweed is gaining a footing along the railroads, and with it the Monarch is probably on the Increase. The writer has not taken the Viceroy west of the range, but Mr. E. N. Brandegee has some specimens from Gold Creek, west of the range, which he collected and which the writer has seen. Cooley re- ports it as occasional near Bozeman, while Wiley calls it rare and local about Miles City. Douglass collected one specimen at Fish Creek. — Coubeaux has collected it at Big Sandy. 104 BULLETIN UNIVERSITY OF MONTANA. WIEDEMEYER'S ADMIRAL Basilarchia wiedemeyeri, Edwards. Plate VII. Fig. 3. Butterfly — It may be distinguished from B. lerquina by its wings be- ing crossed with white bars instead of cream ones, and the absence of a bar at the end of the cell and the yellow apex; it has a submarginal row of white spots on both wings. Expanse 3.00 inches, 77 mm. Early Stages — Caterpillar feeds upon cottonwood. Distribution — The insect is found on the Pacific slope and eastward to Montana, Nebraska and New Mexico. We have not yet taken this species west of the Rocky Mountains, although it is not uncommon east of the range. Brandegee has collected it at Helena, Cooley at Mystic Lake, and Wiley at Miles City. Douglas found it at Madison lake and Jasper Mountain. Taken at Big Sandy by Coubeaux. LORQUIN'S ADMIRAL, Basilarchia lorquini, Boisduval. Plate VII, Fig. 1, upper, Fig. 2, lower surface. Butterfly — Easily distinguished from all the other species of the genus by the yellowish white bar near the end of the cell of the fore wings, and the reddish color of the apex and upper margin of the same wings. Expanse, 2.25-2.75 in., 56 to 62 mm. Caterpillar — The food plant of the caterpillar is poplar, willow, and the choke-cherry. Distribution — This is a western species, quite common in most locali- ties in the state west of the range. It is not k^iown to occur east of the range. The University of Montana collection embraces specimens col- lected by Elrod at various plf.ces in the Mission Mountains, at Flathead and Swan lakes, at Missoula, and on Mt. Lo Lo. BUTTER FLIES ON CHIMBORAZO. "Even butterflies are found at sea at great distances from the coast, being carried there by the force of the wind when storms come off the land. In the same involuntary manner insects are transported into the upper regions of the atmosphere, 16,000 or 19,000 feet above the plains. The heated crust of the earth occasions an ascending vertical current of air, by which light bodies are borne upwards. When Bonplahd, Carlos Montufar and myself reached, on the 23rd of June, 1802, on the eastern declivity of the Chimborazo the height of 19,286 English feet, we saw winged insects fluttering around us. We could see that they were Dipteras, but it was impossible to catch the in- sects The insects were flying at a height of about 18,226 feet Somewhat lower down, at about 2,600 toises (16,680), also therefore within the line of perpetual snow, Bonpland had seen yellow butterflies flying very near the ground. Humboldt in "Aspects of Nature." BUTTERFLIES OF MONTANA. 105 THE WOOD NYMPHS, THE MEADOW-BROWNS. SUBFAMILY Agapetinae. The butterflies belonging to this subfamily are for the most part of medium size, and are generally obscure in color, being of some shade of brown or gray, though a few species are brightly colored. The mark- ings consist almost entirely of eyelike spots, dark pupiled in the center with a point of lighter color, and ringed about with one or more light circles. They are possessed of a weak flight. Most of them are forest living insects, though a few inhabit the cold and bleak summits of mount- ains and grassy patches near the margins of streams in the far North. The family includes chiefly brown butterflies whose markings consist almost entirely of eyelike spots. Some of the western species are brightly colored. The insects are easily recognized by their having some of the veins of the fore wings greatly swollen at the base. The larvae are cylindrical, tapering more or less toward each end. The candal segment is bifurcated, a character that distinguishes them from all other American butterfly larvae excepting those of some of the emperors (Chlorippe). The Chrysalids are rounded; in some cases the transformation takes place beneath rubbish on the ground without any preparation of cell or suspension of the body. Nearly fifty species have been described from America north of Mexico. Key to Genera. 1. Eyes very hairy 2. Eyes naked or nearly so 3. 2.

On this area are two ocelli, round, black, or variable size, and with or without a central point, which is white with blue scales. Behind the cell is a blackish indis- tinct sexual dash in the males. The hind wings have a small ocellus in a yellow ring near the anal angle (often wanting). Underside yellow-brown; the band enlarged and of a paler color; the ocelli repeated, enlarged; the marginal lines distinct; the brown area covered with abbreviated darker streaks, which over the base and disks form somewhat concentric broken rings, limited without by a common dark stripe. On the fore wings it is irregularly sinuous from margin to margin, throwing out a rounded prominence against the cell, followed by a rounded sinus on the median interspace. Across the middle of the cell, and below it, a dark stripe; the extra discal area less streaked. The ocelli vary from none to six, the full number being most often present, disposed in two groups of three, the middle one of each group the largest; all black, rounded, in narrow yellow rings, and with white dots in the center edged by blue, scales.

A larger percentage than of the males have no ocelli on the under side of the hind wings. The above description applies to typical form alope. Variety olympus, Edwards, differs from the above as follows: The males are BUTTERFLIES OF MONTANA. 107. almost black. The ocelli are very small and without wings, but in some examples there is a faint russet or yellowish tint about them, and perhaps on the space between them. On the under side the rings are russet or ochraceous on both wings, and there is a perceptible bronze reflection on the underside of the hind wings, especially in the males. This form is said to occur from Illinois to the Rocky Mountains, and is found abundantly in Montana. However, many specimens with the broad buff band, as in typical alope are found also, see Fig. 85. Olympus and nephele are now given as synonyms, so nephele occurs from New Eng- land to the Rocky Mountains. Five varieties for this species are recog- nized. Early Stages — The egg is conical, marked by about eighteen verti- cal ridges, lemon-yellow in color, hatching in from fourteen to twenty-eight days. The mature larva is 1.25 inches long, cylindrical, robust, thickest in the middle, with two sharp, conical, divergent tails; color yellow-green, head vivid green, Chrysalis is a little more than half an inch long, cylin- drical. The butterfly emerges in fourteen days. The larva feeds on meadow-grass, and the butterfly is found mostly in the open fields or open woods. Var. nephele — Largest of the forms, with buff bands. Ariana is also found in Montana. This is a decidedly dwarfed form, and one that is quite dark. The ocelli are small and well defined. This species is abundant during July and August around Flathead Lake. In searching for insects nephele skirts the roadside by the open woods or undulates through the woods in graceful flight. It becomes so abundant that catching it becomes tame. The specimens show great variation; the species is recognized as being exceedingly variable. At Missoula it is quite common; Brandegee has taken it at Gold Creek, and Wiley at Miles City. Coubeaux has many specimens from Big Sandy.

Carcyonis sylvestris, var. charon. 108 BULLETIN UNIVERSITY OF MONTANA. Butterfly — Expanse of wings, 1.50 to 1.75 inches. The male is dark in color; the female is paler. There are two eye-spots on the fore wings in the usual location, indistinct on the upper, distinct on the lower side of the wings. The under sides of the wings are variable. In the type they are dark; in other specimens they are paler. They may or may not have ocelli on the secondaries. Both the fore and hind wings are abundantly and evenly marked by little striae, and crossed on either side of the median area by obscure, irregular, transverse dark lines, either one or both of which may be wanting in some specimens. Early Stages — The caterpillar is green, cylindrical, tapering before and behind, marked with longitudinal pale-yellow lines. The chysalis is green or black, striped with narrow white lines. The larva feeds on grasses. Distribution — It is found in the Northwest, ranging from British Col- umbia as far as Mexico. In Montana it has been taken abundantly by Wiley at Miles City and Sandstone. Brandegee has taken it at Mt. Ascension near Helena. Allen has specimens from Dillon. Coues col- lected it in 1874 at Frenchman's river and Chief Mountain. BUTTERFLIES OP MONTANA. 109 Collecting Butterflies in Montana. July 22, 1903, was a hot day. For several days the sun had been warm. We were camped on the bank of Bigfork or Swan river at its outlet to Flathead Lake. Our little laboratory, constructed escpecially for out door work, had been a scene of activity within, but no one could stand it long in the swamps or woods on account of the mosquitoes. For two days the little fellows had been especially persistent and villainous. This was taken to be a sign that they would soon go, as they were starv- ing. The sun dries up the ponds and they cannot drink nor lay eggs. Vegetation becomes dry and parched, and does not supply nourishment. A few hot days, followed by a wind, and it was predicted they would go. This had come. Donning my coat containing papers, vials, corks, gloves, and other necessary material, and accompanied by my dog, I started for butterflies. Two or three Arygnnids had been seen, which were very much wanted. Half a dozen other species were on the wing, but all species were doubt- ful, i. e. could not be named from seeing the specimen flying. The field sought was the tamarack forest. The beautiful and stately trees filled the slope of the lake near the laboratory. An occasional Douglas spruce or yellow pine added to the charm of the tamarck forest A wagon road wound through the timber, affording a sunny opening in which the insects love to sport. On either side the tall conifers towered heavenward. A breeze was blowing. The murmur of the pines as they swayed gently at their tops was music to the ear. The timber was not dense. The sun filtered through the leaves and between the treetops, making alternate patches of light and shade. In the forest, therefore, it was thought the airy creatures would sport, where the sun's rays were tempered by the shadow of trees, where the breeze would be less likely to blow against their delicate wings, and where they would be un- molested. The delicate blue bells nodded in the underbrush. Mariposa lilies were on the wane, but an occasional late one showed its delicate cream colored perianth here and there. The twin flower was in bloom, making a carpet where other vegetation was lacking. Service berries were ripe, the blue-black berries hanging in clusters from every bush. Spiraea was gorgeous, just coming into full bloom. A fringe of rock maple, dogwood, spiraea and service berry lined the road, while through the timber they were scattered in great profusion. It was a day for birds. The brilliant plumage of the Louisiana tan- ager flashed in the sunshine as he flew from tree to tree. The call of the western Phebe was heard on every side. The long-tailed chichadee cheerily sang from the bushes by the roadside. Upon an old bole a flicker was calling to his mate, and alternately with his call drumming loudly on the dead tree. While sitting on a log and drinking in the sweetness of the bird music mingling with the sighing of the pines the loud call of 110 BULLETIN UNIVERSITY OF MONTANA. the pileated woodpecker was heard in the distance; for this shy and handsome bird, the largest of our woodpeckers, is still not uncommon in the woods of Montana. I could not mention all the birds seen and heard. One hundred and forty species have been found in this vicin- ity. On that day the woods were alive with birds, sweet with their melody and with the odor of flowers. It was a walk of solitude, but I was by no means alone. In a thick cluster of service berry my dog flushed a ruffed grouse with young. The little fellows could fly a little, and would rise into the top of a little birch or alder and pipe their alarm in great consternation. Their Fig. 85. Where Leto abounds, near the University of Montana Biological Station, upper end of Flathead Lake. somber coats blended beautifully with the surroundings. If one saw a bird alight it was plainly visible. But when once the eye was turned elsewhere and returned to the spot the motionless bird blended with the light and shadow of the forest and with the bark of the trees. Had the little fellows remained quiet they might have passed unnoticed. They will learn, if some pot hunter does not kill them too early. The mother flutters around and makes a great fuss, while the young are scurrying away to places of safety. Scarcely had I left the laboratory when a beautiful Eurymus was seen flying over the bushes by the river bank at the entrance to the forest. Occasionally the delicate butterfly was seen, and I longed to have it. BUTTERFLIES OF MONTANA. HI Carefully I followed until the time was favorable for a sweep, when it was safely landed, much to my delight. Eurymus alexandra is not abundant here, but is often seen sailing gracefully over the tops of the dense bushes, out of reach but aggravatingly near. It was a per- fect specimen, the only one seen or taken during the day. I started before two. Along the road I went slowly, seeking the Argynnids. They were out. Such beautiful and dainty creatures they are. Leto was out in all its glory, but my captures were few. I simply could not do it. I was too awkward, slow, or something. They would not rest. Again and again their course would be near me and I would try, only to fail with an AH, and sigh of regret. Beautiful, dainty, deli- cate creatures, sporting in tne open forest, flitting from open sunshine where the resplendent colors show in all their glory to the shadow of the forest where they may have a little respite. Their gaudy colors make them conspicuous a long distance off, and their large size makes it possible to detect them and distinguish them from others. Of the size of cybele of the east, which was my early delight, it lends a charm to the forest superior in some respects to that given by music of birds or odor of flowers. Gorgeous in array, gentle in movements, short of life, its life nistory unknown, what wonder that it has charm. The day was too hot for Leto to be in the open. I sought, but in vain. A return to the forest brought its company. Its flight is rapid and undulating. Rarely did it rest. Pursuit into the forest beyond the road was impossible be- cause of brush, fallen logs, stumps and stones. Again and again I made a desperate sweep for a dark female or a more brilliant male. Thrice was I successful, but many times did I fail. But one sweep was granted. With the swish of the net through the air it was off in that peculiar zigzag course common to most butterflies, the angles of flight and the lines of flight as sharp and as numerous as the zigzag lines on the wing. It was not so abundant as formerly, for annually it has been taken near the laboratory for five seasons. Other Argynnids were out. Hesperis and one I took to be atlantis, but which may prove to be different, were on the wing. The time to take pie is when it is passing. The time to take butterflies is when they are to be had. There is no more fatal error than to fail to take specimens because they are plentiful. They may not be so to-morrow. Every naturalist will no doubt recall irreparable losses because he failed to take specimens when they were to be had, but delayed for a more convenint season. Atlantis was abundant. It is not so large nor so gorgeous as Leto, but is nevertheless beautiful. The underside of the species captured is dark buff with a slight submarginal band. It was abundant. It seemed to be especially fond of resting on Spiraea lucida. It rested often, and was not difficult to capture. The afternoon's catch resulted in 23 speci- mens of this and Hesperis. Atlantis was frequently interrupted in its rest on Spiraea lucida by Phyciodes tharos. Whenever a tharos was near it would invariably fly to the atlantis on the shrub. They would arise together and circle about before separating. Frequently the two were taken together. Tharos was invariably the aggressor. Whether it 112 BULLETIN UNIVERSITY OF MONTANA. dislikes Atlantis or not was not apparent. It appeared more a curiosity move, but was not displayed toward the others. Phyciodes tharos was abundant, and had been several days. Light, graceful and delicate, it rested airily on the broad white umbels of the Spiraea, when it would spread its wings to their fullest extent and fan them gently up and down. Its flight is more graceful and undulating than that of the Argynnids. It moves more slowly, keeps in the open, and for that reason was not difficult to capture. It was taken while waiting for others to appear. Lycaona meliasa, the orange-margined blue, was less abundant along the roadside than on former days. It is a delicate little butterfly of wondrous beauty~in color. It expands only about an inch. The males are blue-violet above with a delicate fringe or border of white scales to the wings. The female is dark brown with eye spots on the wing margins, surrounded by orange, giving the appearance of an orange band. It is underneath that the gorgeous colors appear. The spots with their border of gold and dust of silver, on a light grey background, and set out in contrast to the pure white brush like margin, call for admiration from all. Along the roadside they slowly flitted, mostly males, but now and then a female, occasionally seeming to hobnob with tharos, but always in graceful contrast to the more swiftly moving Argynnids. They were easy to take, but previously many had been captured. A single Lorquin's admiral Basilachia lorquina, was captured as it was being gently wafted along a side road by the breeze. Down among the red cedars along the rocky lake shore a female Par- nassius smintheus was resting on a weed. She was royal in her array of delicate red, creamy white and drab gray. Upon the hilltop one must usually search for smintheus, for it is an alpine species, among the rocky summits where grow the sedum and saxifrages. It is rather suprising to find it at the level of the lake, about 2,900 feet, yet on several previous occasions it has been seen and captured. Shortly after four in the afternon the trees were casting longer shad- ows, and 'already the cool of evening was being felt in the woods. The sun in the insects' god. When it shines all is life and activity. The whirr of the bettle's wings is heard, and the bumble bee hums from flower to flower, flies and gnats fill the air, dragonflies and damselflies skim the surface of the water, and butterflies disport themselves on airy wing. But when a passing cloud obscures the sun, or evening approaches, every form of insect life, except the mosquito and gnats, seems to feel the depression, and goes to cover. Where or what the cover is, who can tell? Two hours of brief collecting, and the work of the afternoon was over. The net result was forty butterflies and two moths, embracing the following species: Colias alexandra, Argynnis atlantis, abundant; Argynnis leto, less common; Lycaena melissa, quite common; Phyciodes tharos, common; Basilarchia lorquina, a single specimen; Parnassius smintheus, a single specimen; Argynnis hesperis, rare; a small black but- terfly, of undeterminable species, two specimens; total, forty speci- mens, eight species. This was a good day. Many and many a day in Montana has resulted in a third of this catch. Both species and specimens are lacking in BUTTERFLIES OF MONTANA. 113 numbers as compared with collecting in my boyhood days, when I used to pick them up on the common or in the clover meadows in much greater numbers. The next afternoon I tried again. The sky was obscured by light fleecy summer clouds, which later thickened for rain. Atlantis was some place else, and but a few were seen. Leto was very scarce, not one captured. Melissa was yet in numbers, largely females whereas the catch of the previous day was largely of males. Tharos was still in evi- dence. A single Satyrus ofympus was added to the collection. Not a smintheus was in sight, not an admiral. A male Colias alexandra has- tened from the road to the bushes and eluded capture. It was a close day but a poor catch. The above is typical of good days in Western Montana. Wylie com- plains bitterly of the scarcity of butterflies in the eastern end. And yet the chase is not without its charm and its reward. The field is new, The unknown species lends zest to the search. "It isn't this not that, it must be something new," is interesting and cheerful to hear. It shows the speaker is thinking. And the greut state, with its wealth of life, beckons to the ambitious entomologist who may be the first in his locality, offering him a rich if not prolific field. To the collector will come a love for the woods and fields. They will not be places of solitude, for there he will find friends, and will commune with nature in that manner which brings the richest reward, when he is alone. He will feel the thrill of joy at first holding in his grasp a new find, for new they must be for years yet. His will be the pleasure, perhaps, of finding something new about some abundant species, for "Unknown" is yet written after many species herein mentioned. Nay, perhaps his small collection may be the humble beginning of a larger work, leading to broad fields and to the fascination which comes to him whose horizon is broad, widening with each day's work, limited only by physical limitations. Love for the humble little creatures of the air, love for the beautiful in nature, as revealed in their rich ornamentations, love for nature itself, with a reaction upon the in- dividual, making him more appreciative, more happy, and more contented, will be the final reward of the young collector.

Wings dark brown, ocelli pupiled with white and surrounded with red. epipsodea. THE COMMON ALPINE, Erebia epipsodea, Butler. Fig. 86, 87. Butterfly — The wings are dark brown, almost black, pupiled with white, and broadly surrounded with red near the outer margin of the fore wings, and with three or four ocelli on the upper side of the nind wings. The spots on the upper side reappear on the under side, and in addition -the hind wings are covered by a broad, curved, median blackish band. Early Stages — The caterpillar feeds on grasses. Distribution — It ranges from New Mex- ico (at high elevations) northward to Alas- ka. It is common on the mountains of British Columbia. The collection in the University of Montana contains specimens from Sinyaleamin lake and McDonald lake in the Mission Mountains, Flathead Indian Reservation, the Tobacco Root range, Gey- ser Basin and Missoula. It has been collected by Brandegee at Helena, and reported common. It has been taken by Cooley at East Flathead in Park county, at Shields river, Park county, at elevation 6,400 feet, at Mystic lake, Gal- latin county, at 6,700 feet, and at Bozeman. Fig. 86. Venation of Erebia epipsodea Fig. 88. Erebia epipsodea, lower surface. Fig. 87. Erebia epipsodea, upper side. This butterfly is one of the early spring insects. The earliest about Missoula are Aglais milberti and Eugonia californica. Before the hot days come on Erebia epipsodea seems to be at its best. The last of May and the first days of June are the times when it is at its best. Its flight is like Cercyon, and the species is easily recognized by its flight. BUTTERFLIES OF MONTANA. 115 Genus COENONYMPHA, Westwood. 1 The Ringlets. Small Butterflies. The costal, median and sub-median veins are all strongly swollen, as may be seen in figure 89. The palpi are very heavily clothed with hairs, the last joint quite long and porrect. The antennae are short, delicate, gradually but distinctly club-; bed. The eyes are naked. Both wings on the outer margin are evenly rounded. This genus is distributed throughout the tem- perate regions both of the old and new world, and includes in our fauna a number of forms, the most of which are peculiar to the Pacific coast. They are very variable as to the number of spots and ocelli, and vary greatly in the color of the under side. It is no infrequent thing to find the ocelli and spots differing on the two sides of the same insect. Key to species.

Female like the male. Early Stages — Unknown. 116 BULLETIN UNIVERSITY OF MONTANA. Distribution — Ochracea has a wide range, from Lake Winnipeg in British Columbia to Kansas and west to California. This dainty little insect is abundant about Missoula in early spring. In May and early June it sports along the open hillsides, being most abundant in mountain gullies where moisture lingers, or along the banks of streams. The university collection embraces specimens from McDonald lake in the Mission Mountains, Missoula, New Chicago, the Tobacco Root range, and the Ruby Mountains. It is common about Helena according to Brandegee. Wiley has it in his collection from Miles City, and Cooley has collected it at Forsyth and Bozeman. Coubeaux reports it moder- ately common in Bear Paw Mountains. Coues collected it along the 49th parallel in 1874. Remarks: — Dr. Henry Skinner, in his revision of the American species of the genus Coenonumpha. Trans. Amer. Ent. Soc., Vol. XXVI, says of this species: "That is quite a variable species. The upper side differs very much in different specimens in regard to the distinctness with which the spots below show through on the upper side. The color of this spe- cies, in conjunction with the distinct ocellus on the premaries below, serve to distinguish it from all others." He calls C. brenda Edwards a synonym of C. ochracea, and says it is only a much spotted ochracea. "If we give names to all the variations of ochracea we would have six names for the species." THE RINGLESS RINGLET. Coenonympha elko, Edwards. Butterfly, IvTaTe — Expanse, .95 to 1.00 inch, 25 mm. Upper side pale ochre-yellow, immaculate; fringes concolored. Up- per side of primaries nearly same ochre-yellow over basal area and part of disk, limited without by a slightly sinuous and crenated edge of deeper color, much as in the allied species; outside this, slightly ochraceous next the inner angle, but yellow-buff over apical area. The secondaries have the basal area uniform grey-brown, the outline distinct and in strong con- trast with the remainder of the wing which is yellow-buff. Very slightly gray; the outline is irregularly crenated, with a deep sinus on the upper sub-costal interspace, and another on the lower disco-cellular interspace. Female — Expands 1.00 to 1.02 inches. Upper side like the male. Beneath, the area just outside the crenated edging on disk of primaries is yellow for a little distance, then tinted ochraceous to the margin, in one example a minute black dot in the disco-cellular interspace with white center, in another no dot; secondaries as in male, basal area one shade of gray, with distinct crenated outline, and beyond a yellow or buff ground to the margin, very little dusted with gray. Distribution — It occurs in Vancouver's Island, Washington, Oregon, Nevada, Montana, Utah and Idaho. Remarks: — Very much like ochracea, but it is distinguished from others by the absence of ocelli on both wings, above and below. Accord- ing to Edwards ampelos and elko are same. He has found two speci- mens with spots on the secondaries. THE PLAIN RINGLET, Coenonymph tiphon, var. laidon, Borkh. Butterfly — This Butterfly was described by Edwards as C. inornata Dr. Buckell called attention to its resemblance to the European form. His view is confirmed by Dr. Skinner in his recent paper previously re- ferred to. The following is Edwards' description of inornata, and there- fore of laidon. BUTTERFLIES OF MONTANA. 117 Male — Expanse, 1.40 inch, 35 mm. Upper side ochrey-brown, lighter in the disk of all wings; costal margin of primaries and abdominal margins of secondaries grayish, no spots above or below; fringe gray, crossed by darker lines. Under side: primaries same color as above, from base to beyond the middle, then a transverse sinuous ray of paler color, and be,- yond this to hind margin grayish; sometimes this ray disappears, the basal color extending nearly to the apex; secondaries gray, with a slight gray- ish tinge, darker from base to middle, and this shade separated from the paler margin by a transverse tortuous interrupted ray, the course of which is parallel to the hind margin. Female — Wholly dull ochrey-yellow, marked as in the male. Dr. Skinner adds: "This species is readily distinguished by its rich dark color, being the darkest of all the spscies except haydeni. Like- all the other species it has ocelli. Mr. Edwards' specimens were evi- dently devoid of ocelli, as he says 'No spots above or below.' " Distribution — The species occurs in Montana, Minnesota, British Am- erica and Newfoundland. Examinations show the collections to have/ one from Mount Lo Lo by Elrod and one from Miles City by Wiley. Col- lected by Coues in the mountains along the northern border in 1874.
