XI JANUARY-MARCH, 1909 No. 1 MEETIXG OF DECEMBER 10, 1908. The 226th regular meeting was held at the Saengerbund Hall, 314 C street, X.W., President Hopkins in the chair. Messrs. . \inslie. Burgess, Burke, Busck, Crawford, Ely, Gill, Heidemann, Hopkins, Hyslop, Jenne, Jones, Knab, Kraus, Lawford, Morgan, Patten, Quaintance, Sanders, Sasscer, Schwarz, Townsend. Ulke, Van Horn, and Webster, members, and Messrs. Braucher, demons, Dovener, Hammar, Nelson, Russell, and Wilson, visitors, were present. Messrs. E. A. Back, R. A. Cushman, A. G. Hammar, G. E. Merrill, H. M. Russell, E. G. Smythe. and H. F. Wilson, of the Bureau of Entomology, U. S. Department of Agriculture, and Mr. Douglas demons, of the Division of Insects, U. S. Xational Museum, were elected active members of the Society. The following officers were elected for the year 1909: Presi- dent, Otto Heidemann; First Vice-President, F. M. Webster; Second Vice-President, A. L. Quaintance ; Recording Secretary, I. C. Crawford: additional members of the Executive Com- mittee, L. O. Howard, C. L. Marlatt, and H. G. Dyar. An amendment to the Constitution, uniting the offices of Corresponding Secretary and Treasurer, was proposed. In ac- cordance with the Constitution this could not be voted on until the next regular meeting, so the Corresponding Secretary and the Treasurer for lf'OS consented to hold office until the matter \vas settled. 1 2 PROCEEDINGS ENTOMOLOGICAL SOCIETY Dr. Hopkins stated that his address as retiring President was as a Vice-President of the Washington Academy of Sciences. Dr. Hopkins stated that his address as retiring President was not ready for the evening, but would be delivered in the near future. He said that he had been busy completing a work in which he had been engaged for years and he was glad to an- nounce to the Society that the monograph of the scolytid genus Dendroctonus would soon be published by the Bureau of Ento- mology of the Department of Agriculture. It will be issued in two parts, the systematic part as a technical bulletin and the economic as a regular bulletin. He explained the main feat- ures of the monograph and exhibited a number of plates and maps. He said that it would be a foundation for all future work on the Scolytidae and should also prove a great help to other workers in the rhynchophorous Coleoptera. It shows strikingly the great importance of careful systematic work as a basis for good economic work. Mr. Ouaintance congratulated Doctor Hopkins upon the thoroughness of the work and said that in this respect it should serve as a model for other entomologists. Mr. Schwarz also made some complimentary remarks and called attention to the fact that predaceous insects, being in- dependent of host plants, are better indicators of life zones than are the plant feeders. INFORMAL MEETING OF JANUARY 2, 1909. An informal meeting in honor of the visiting entomologists present in the city after attending the entomological meetings held in Baltimore during the sessions of the American Associa- tion for the Advancement of Science, was held at the Saenger- bund Hall, 314 C street N.W., on the evening of January 2, 1909. Messrs. Ainslie, Barber, Burgess, Burke, Busck, Caudell, demons, Couden, Crawford, Currie, Dyar, Hammar, Heide- mann, Hinds, Hooker, Hopkins, Hunter, Jenne, Knab, Kraus, Marlatt, Morgan, Morris, Pergande, Popenoe, Schwarz, OF WASHINGTON, VOLUME XI, 1909. 3 Smythe, Townsend, Van Horn, \Vebb, and Webster, members, and Messrs.

Tracy, Pettit, Cooley. Lowe, Brooks, Worsham, Hinds, and Bird, visitors, and Messrs. Schwarz, Hunter, Dyar, Hopkins, and Marlatt, members. MEETING OF JANUARY 14, 1909. The 227th regular meeting of the Society was held at the Saengerbund Hall, 314 C street N.W., on the evening of Jan- nary 14, 1909, Mr. C. L. Marlatt, host, the President in the chair. Messrs. Ainslie, Barber, Bnsck, demons, Crawford, Davis, (iill, Heidemann, Howard, Hunter, Jenne, Jones, Knab, Kraus, Law ford, Marlatt, Morgan, Patten, Phillips, Popenoe, Ouaintance, Sanders, Schwarz, Smythe, Ulke, Webb, and Wilson, members, and Messrs. Braucher, Kelly, Lowe, Vick- ery, and WTood, visitors, were present. The minutes of the 226th regular meeting and of the special meeting of January 2, 190*', were read and approved. The President announced the substitution of Dr. Phillips as chairman of the Auditing Committee, for Professor Webster, and the committee then reported, the report being adopted by the Society. The names of Messrs. K. O. G. Kelly, F. B. Lowe, and R. A. Vickery were proposed for corresponding membership and re- ferred to the Executive Committee. The change in the Constitution uniting the offices of Cor- responding Secretary and Treasurer was adopted, PROCEEDINGS ENTOMOLOGICAL SOCIETY Dr. Phillips was nominated for the office of Corresponding Secretary-Treasurer, and the rules being suspended the Secre- tary cast the vote of the Society for him. Mr. E. L. Morris sent in his resignation, which was ac- cepted by the Society with regret. The Society requested Doctor Howard to give a paper on the older members of the Society, to be delivered at the anni- versary meeting on the occasion of the twenty-fifth anniver- sary of the founding of the Society. Doctor Howard then presented a paper* entitled "Four Poineer Economic Entomologists," which was discussed by Messrs. Ulke, Gill, Schwarz, Davis, and Lowe. The Constitution of the Entomological Society of Washing- ton, as amended, stands as follows: CONSTITUTION. ARTICLE I. NAME.

In the life of a nation, twenty-five years is but a moment of time. In the life of a great scientific society, a quarter of a century is but a brief period. Mut in the life of an individual, twenty-five years becomes a very appreciable space. Think, for example, of the individuals composing our Society, which commemorates its twenty-fifth anniversary to-night. At the time of its founding, of the eleven men present, Riley, Barn- ard, Johnson, Morris, and Schafhirt are gone, and of the others only Mann. Schwarz, and the speaker remain in Wash- ington. Of the twenty-six members listed in the Proceedings published nearly two years later, teil have died, and only seven remain in Washington. Morris was already an old man, but lived eleven years longer, until 1895, when he died at the ripe age of 92 — a notable example of physiological value of ento- mological pursuits. Riley and Uhler were in their prime. Heidemann and Pergande were still young. Marx and Lug- ger were in their vigorous forties, men of wide experience and of infinite humor, whose droll stories will live perhaps almost as long as their recorded scientific achievements. Schwarz was in his active thirties, but he looks as young now as he did then, and is mentally if not physically as active. Casey and Smith and Mann and Hubbard and 1 were still in our hopeful twenties, all of us to round out the following quarter century except poor Hubbard, the best of us all. Ashmead and Mar- latt, Fox and Hopkins, Webster and Ouaintance, Dyar and Currie, and the rest of you appear on the scene much later. Some of you, Crawford and Phillips, our Secretaries, with P>urke and Webb and others, were perhaps being spanked and put to bed that memorable night in February, 1884, while still others were disembodied spirits floating around in the ether waiting to be born and absolutely uncertain as yet whether you could select parents who would allow you to become entomol- ogists or not. Many of the facts connected with the first ten years of the Society's existence have been summarized by the speaker in a paper read at the one hundredth meeting, June 7, 1894. Cer- tain intimate facts concerning the composition and business of the Society were treated in a more or less statistical manner, but a number of interesting and important facts were brought out, and, reading it over agctin after a lapse of fifteen years, I am particularly impressed by the summary of the character of papers read in those first ten years. While the communications OF WASHINGTON, VOLUME XI, 1QQ9 9 had been mostly short, and published as a rule rather in ab- stract than in extenso, they were for the most part of great biological interest. There were almost no classificatory papers. They treated of habits or transformations, of geographic distri- bution, of parasitism, of technique, of insect physiology, of ev >- Intionary problem-, of insect ])roducts. of the relations of llowers to insects, and subjects of this character. It is notable that only 13 papers out of a total of 341 even touched upon economic entomology. There was a reason for this, and that reason perhaps was largely due to the personality of the first President of the Society. It is fairly well ex- pressed in his retiring' address at the close of the fir-1 \var of the -Society's existence. He wrote (p. 24, vol. 1, Proceeding Entomological Society of Washington) : "\Ye have here in Washington a number of collectors and amateurs and some well-known specialists, in addition to the force of the Entomological Division of the Department oi Agriculture. The Division constitutes a force that I feel justly proud of, and the working of which has been commended by those who have had occasion to become familiar with it. Vet how far it falls short of my own ideal and- of the necessities of the country, or how difficult it is to build it up to that ideal under the unfortunate political unscientific atmosphere that pervades the Department, no one more fully appreciates than myself. The fact remains, however, that there is a good num- ber of active observers whose interest in the subject of ento- mology is not confined to the particular biologic and economic work of the Division, but encompasses much that could not properly be brought within its scope. The members of the Division have naturally become member- of the Society and form a good basis for its existence; yet it would be manifestly unnecessary, if not improper, for the members of the force to band together in private simply for the discussion of those en- tomological subjects \\hich the\ art- working with me to further in official capacities. It was to get away from official surround- ings— away from the work of the U. S. entomologists — that the members of the Division decided to join in the organization of this Society *. From this standpoint it was perhap- unfortunate that you chose me as your presiding officer; for I feel deeply that we should avoid everything that may create the impression that the Soeietv is but an echo of the official organization." It would be most interesting, if there were time, to compare in a similar manner the character o| the- papers read and meet 10 PROCEEDINGS ENTOMOLOGICAL SOCIETY ings that have been held in the last fifteen years with those re- corded in my review of the work during the first ten years. There has been a. decided change. The Proceedings are not less valuable, they are undoubtedly more valuable, since per- haps the majority of the communications of the first ten years were short though interesting notes. Nevertheless, I doubt whether even such an enthusiastic entomologist as dear old James Fletcher could have written me about the Proceedings of the past five years as he did after reading the first number of the Proceedings published by the Society in 18X6, that he had taken it up after dinner and had not laid it down until he had read the last word at midnight ! This means that our Proceedings in the first place contain more lengthy systematic papers, and in the second place of a more serious and more permanent character. Even Fletcher's letter, however, need not indicate that the early Proceedings had any of the character of romance, and any of us glancing through the pages of that first number must realize that the man who collects in the field and who closely studies living in- sects will find there the observation; of others who did the same and who did them with their eyes and minds open. In his address, 'Riley spoke with pride of the Division he had founded. Let us see just what was the composition of that Division at that time. It consisted of Riley, himself, of Mann, of Pergande, of Schwarz, of Barnard, of Koebele, of Smith, and of Howard. Marx was employed on another roll as the general artist of the Department, and Heidetnann as gen- eral engraver for the Department. Riley went on to state that the Division fell far short of his ideal and of the necessities of the country, and spoke of the difficulties of building it up to that ideal under the unfortunate political unscientific atmosphere that pervaded the Department ; and it would be very interesting to talk it over with him were he still with us, and find out how far the organization now falls short of his ideal. We are perfectly aware that it has not yet satisfied the necessities of the country, yet, as imaginative as Riley was and filled as he was with the evidences of that artistic temperament which ac- counted for some of his peculiarities, I hardly believe that he would have expected at this time a larger or more efficient or- ganization than now exists. Against the eight men he then had on his rolls, we have more than a hundred scientifically trained, and, against the appropriation of something like $20,000 which then was spent by the Government upon entomological work, funds now exceed half a million per annum. OF WASHINGTON, VOLUME XI, 1909 j} But far better than this is the change in the atmosphere. What Riley termed "the unfortunate political unscientific at- mosphere that pervades the Department" has disappeared The present atmosphere is one of progress, of enthusiastic, forceful, energetic progress, but a progress that shall be gained abso- lutely by the strictest and most truthful methods- — in other words the methods of true science. This characterization is one governing, 1 believe, all of the scientific bureaus under the I'nited States ( iovernment at present. It was written only with the Department of Agriculture as a whole in view, but it should surely be extended to cover all, and in this complex whole the llureau of Entomology bears its important part and de.sires of all things the discovery of scientific truths in the interest of scientific truth for the benefit of the people of the United States and humanity at large. It is a mistake to believe that we should not talk over our official work at our Society meet- ings. Let us talk it over among ourselves as much as possible, in season and out of season. Where we can get the greatest number of entomologists together is the best place to talk it over. When it comes to publication, that is another matter. Kesults obtained by official labors should be published In- official sources, provided they are appropriate to such publica- tions. Incidental results of biological interest may be published in the Proceedings of the Society or elsewhere, according to conditions. One unique feature of the Society that has developed during recent years has been the broadening of certain of its discus- sions beyond the confines of strict entomological science. Fer- no\v, ( lill, \Yaite. Stiles, Holm, Yaughan. Sudworth, Pollard, K. L. Morris, Cook, and other botanists and zoologists, and even paleontologists, have joined us, realizing both that ento- mologv is an enormous science and that the Entomological Societv is in many ways the livest scientific society in Wash- ington. How often have we seen them sitting listening with courteous interest to the more technical papers, their faces lighting up with an interest more than merely courteous when a topic even slightly impinging upon an idea of broad biologic capabilities was suggeMed, and springing to their feet to take part in a discussion soaring far beyond insects and becoming as broad as the problem of life itself. This has meant much to this Society and has made it unique among all the entomo- logical societies of the world. We strict entomologists owe much to these men. and among them especially to Dr. Theodore ( iill. To have had the privilege of this intimate association with this great naturalist, to have heard at first hand and on 12 PROCEEDINGS ENTOMOLOGICAL SOCIETY so many occasions his views on so many broad subjects, backed by bis mature judgment and supported by his great wealth of knowledge, is an experience and a pleasure which none of us will ever forget. But in speaking thus of Doctor Gill, we must not fail to men- tion another, and this one an entomologist. I think the newer men already appreciate what I am about to say, but I must emphasize it. Years ago B. Pickman Mann once said to me, r'The principal reason for the existence of the Entomological Society is E. A. Schwarz.'1 Is it not true? What an indiffer- ent meeting it would be without him ! There are volumes upon volumes of entomological knowledge packed away in his brain, and with tables of contents and elaborate indices prepared for instant use. This unexampled store of entomological infor- mation is always at hand and ready for use in our discussions- is always ready to be imparted in the kindliest and most human- istic spirit to every worker. We should perhaps paraphrase Mann's saying, and put it thus: What has made the Entomo- logical Society valuable to us beyond all other organizations has been the constant presence and participation in its discus- sions of Eugene A. Schwarz and Theodore N. Gill. The most cursory of glances through the Proceedings will serve to emphasize what has just been stated. On one page we see that Mr. Schwarz spoke on the composition and extent of the coleopterous fauna of Alaska, and on the next page Doctor Gill is reported to have said that Mr. Schwarz's statements were reinforced by the distribution of other animals, discussing the mollusks and fishes and mammals. And so it goes. While the discussions have been broad beyond the confines of insect knowledge the papers read have practically been con- fined entirely to the different aspects of entomological science. There was one exception, however. On November 1, 1894, Doctor Gill presented a paper on a remarkable new family of crabs, and stated that he thought himself justified in presenting the paper before an entomological society for the reason that in his opinion the Crustacea are more closely related to the Insecta than are the Arachnida. A vigorous discussion ensued. The present speaker frankly stated that he had voted against the reception of the paper by the Program Committee on the ground that however loose the definition of the word "entomol- ogy" may be, it is generally understood to refer to the class Insecta, and that the scope of this class is so enormous that the tendency of the Society should be to contract rather than to expand the range of topics considered at its meetings. The ad- OF WASHINGTON, VOLUME XI, 19Q9. 13 mission of papers on Arachnida had been from the beginning largely a matter of courtesy and precedent. Doctor Gill, on the other hand, argued that the word "ento- mology" should apply to the whole group Arthropoda, and T wonder whether he holds the same view now. T once heard Doctor Gill at the Cosmos Club arguing vigorously against the possibility of the existence of such a creature as the sea-ser- pent,buton the very next night, happening in to the club, I heard him give an elaborate argument, and a quite convincing one, that there is a strong possibility that such a creature as the sea-serpent may still exist! That showed me for the first time that Doctor Gill rather likes to argue, and that, at the Cosmos Club it makes very little difference which side of the argument he takes. I hope and believe that it is different at the Entomo- logical Society. I '.tit in regard to the crab paper. I am glad to state that Mr. Schwarz agreed with me. He said that arachnologists have af- filiated with entomological societies largely because they are so few in number and because there are no more nearly related associations of specialists. There was no hard feeling in the discussion, which changed immediately into a broad morpho- logical field apropos to the hind legs of the crabs under discus- sion having apparently developed into breathing organs, and the whole group of insects was discussed for comparable de- velopments and a number were pointed out. lUit it is notice- able that no more papers on crabs have been read before the Society since that night. How many interesting meetings have been held ! A long succession of them stand out plainly in my eye. I recall the earnest faces ; I can hear the voices of all who are gone : I can hear the ready laughter which followed a quaint remark of Lugger or of Marx, and even now it bubbles out as sponta- neously at one of Srhwarz's humorous turns of expression. One of the meetings which none of us who were there will forget — and there were only eight of us — was held February 7, 1S(>5. at my house in Georgetown. It had been snowing all day. and from 3 o'clock snow l.ad been coming down so rapid- ly that it was impossible to see ten feet in from of one. T ex- pected no guests as I looked out into the still whiteness, but at 7.45 the door-bell rang, and ! opened the door to find a white pillar standing there which shook itself and re\<-alcd the smil- ing face of Doctor Gill. The bell rang again, and in came Schwarz and Marlatt. and then lienton and Coquillett. and finally a shouting was heard without: the dour was opened, and there was Ashmead and a cab driver floundering around 14 PROCEEDINGS ENTOMOLOGICAL SOCIETY in the snow trying to find poor old Ashmead's overshoes, which he had lost, and while the search continued a stalwart figure in hip-boots arrived and it proved to be Dr. C. Hart Merriam in his north-western mountaineer garb, come to the meeting on special invitation to hear a paper on the geographical distribu- tion in the United States of certain insects injuring cultivated crops, which was one of the early attempts to use Merriam's now famous life-zone maps in a practical way. Everyone was in goods spirits that night, and the geographic distribution dis- cussion was a lively one. It covered the whole field of zoology and botany. Ashmead contended among other things that par- asites always followed their hosts and Doctor Merriam retort- ed that he had never known the bedbug to occur in the Boreal Zone, whereupon Doctor Gill stopped that part of the discus- sion by the remark that we can not trust to negative evidence, for upon negative evidence alone he himself would be inclined to say that the bedbug does not occur in the city of Washington ! The social feature of the meetings of the Society has al- ways been an important one. It is good to have more men. It is especially good to have the great influx of young men who have come to us since Congress has begun to be so liberal with its appropriations. But it is nevertheless with regret that we older fellows see the custom of meeting at one another's homes pass away. This custom is revived for tonight by the warm- hearted hospitality of Patten, that loyal member who has struggled with our complicated accounts and large financial transactions as treasurer of the Society for so many years. P>ut this, in theatrical parlance, is a one-night stand only. We think of the evenings in the homes of Riley, Marx, Schwarz, Smith, Heidemann, Mann, Fox, Dodge, Fernow, Ashmead, Gill, Marlatt, Stiles, Dyar, Patten, Pollard, Banks, Benton, Chapin, Quaintance, and others, and of the charming meetings in Baltimore with Uhler, with regret. The social feature is retained, it is true, at our present enjoyable meetings at Saen- gerbund Hall ; but they lack the intimate quality which ren- dered the old ones (and this one, thanks to Patten) so de- lightful. In those early days entomology and beer went together. There were good reasons for this. Marx, Schwarz, Heidemann, Pergande, Lugger, Schoenborn, Ulke, were all Teutons, as their names indicate ; John B. Smith's real name is Johann Schmidt. At that period the German university idea domi- nated scientific America. There were thousands of young Americans in the German universities each year. The Amer- ican university students adopted in part the customs of the OF WASHINGTON, VOLUME XI, 1909. 15 German university students. Some of us had been in Germany. . \shmeacl spent a year in lierlin. Stiles, having returned to this country, hardly knew whether he was speaking English or German. The after meetings of the Entomological Society were inter- esting; the conversation was good: the refreshments were un- limited in quantity but limited in kind; you could have light beer or dark beer, and that was about the extent of the varia- tion. It was my custom to order two cases of beer, each of 24 bottles, for an average attendance of 7 or 8, and I always made the arrangement with the grocer to return those bottles which were not empty, as well as the empty ones, but it soon became a standing joke between us that it was unnecessary to make any provision concerning the nnempty bottles. I am not sure that this custom, which no longer holds, was a good one. I am not sure that it was a very bad one. So far as I know, it never seriously affected the health of any of the members, but on the whole perhaps it was unfortunate and I am inclined to believe that the present method is the best. I should dislike to see some of the younger members of the Society drink as much beer as some of us did at their ages, and. while I would not vote the prohibition ticket as Banks does, I believe that I'.anks was about right when the Society met at his house for the first time and he gave us hot lemonade and cold lemonade and some very excellent raisin cake. It is true that a few glasses of beer will make a stupid remark sound witty, but there was no necessity for any such stimulus to the imagination in the old days, because all of the remarks were witty. There are so few of us left that it will be interesting perhaps to say something about the men who attended that organiza- tion meeting in 1884. Doctor Barnard was an extremely tall man. 6 feet 3 at least, very slender, with a full blond beard. He had been a professor in lo\\a. an inspector at Pennikese under Agassiz, had occupied Comstock's chair at Cornell while ('omstock was in Washington, and was now working away on machinery with which to fight the cotton caterpillar, and wa> principally interested in the perfection of the cyclone nozzle. Albert Koebele was a young German of about 27 or 28, recently come from New York, where Professor Riley had met him at one of the meetings of the P.rooklyn Entomological Society, and was acting as preparator in the Division of Ento- mology. His fnltnv successes in discovering and importing \<>7'ius cardinally and other beneficial insects were as yet little dreamed of. Judge Laurence Johnson was a man of perhaps 55 or 60years 6 PROCEEDINGS ENTOMOLOGICAL SOCIETY of age, who had been an agent of the Entomological Commis- sion and afterwards of the Division in the study of the cotton caterpillar in Mississippi. He lived at Holly Springs, in that State, and was much interested in entomology. He was at that time in Washington on a visit in connection with the cotton cat- erpillar work. The judge was a fine man and made many friends among the entomologists here. He is probably still alive, although I have not heard from him since September, 1905. He wrote me at that time from Pachuta, Miss., relative to mosquitoes. He stated in this letter that prior to 1858 to 1859 mosquitoes were unknown at Holly Springs, Miss. They were carried there by the new Mississippi Central Railroad. The judge, in IS/6, caught the first Stcyomyia at Holly Springs and took it to be a new species of Culex. Now mark an inter- esting thing: in 1853 Holly Springs did not quarantine against the fever, and refugees came there ; persons with the fever were brought there, and got well or died without communi- cating the disease; in the scourge of 1878, however, Holly Springs being known as an immune place, people swarmed in there and 'yellow fever patients were brought, but, as just shown, the Stcgomyia had been brought in by the railroad, and the population of Holly Springs was more than decimated. Mr. 1). P. Mann is still with us in Washington. At that time he was Assistant Entomologist, and was engaged .largely in work on the Bibliography of Economic Entomology. Doctor Morris I have already spoken of. At that time he was well above 80 years, and very stout and florid, with per- fectly white hair and smooth face. He was then pastor emer- itus of a Lutheran church* in lialtimore. He had done no actual entomological work for many years, but was still greatly interested in the subject and full of anecdotes of the earlier entomologists. While I was writing these words this morning the door of my office opened, and in came old Professor Cyrus Thomas, 84 years of age, but mentally as active as ever. He came in to suggest the idea that certain non-migratory locusts, after a succession of dry seasons, grow longer wings and become migratory. And lie went on to say (mark the coincidence), "J- Ci. Morris came into my laboratory once years ago, when Darwin's book on The Origin of Species was first making such a stir, and while he was objecting to the whole idea of evolu- tion, I told him this about the grasshoppers; and he said, 'Thomas, what arc we coming to?' Yon can imagine the scene. These two ministers of the (iospcl, having the advantage over other members of the cloth OF WASHINGTON, VOLUME XI, 1909. 17 in being naturalists, puzzling their brains already in the effort t<> harmonize the facts of nature with the teachings of the church. Professor Riley needs no extended mention here. The liter- ature of entomology is full of references to him, and his per- sonality has been described in many biographical records. Dr. A. J. Schafhirt was a man of middle age and fine per- sonal appearance. He was a druggist, and kept a shop in the neighborhood of the Government Printing Office. He was much interested in entomology and, naturally, especially in the insects affecting drugs and stored products, but I think at one time he had made a general collection of insects. Alonzo H. Stewart was at that time quite a boy, although he was the chief of the pages of the Senate. I imagine that he could not have been more than 18 or 19 years of age at the time of this initial meeting. lie was greatly interested in insects, and during the early meetings frequently came with interesting specimens for exhibition and with many questions to ask about them. The other two persons present, Mr. Schwarz and myself, need no description to this assemblage. Letters were read from Colonel (then Captain) T. L. Casey, 'Mr. C. R. Dodge, and Professor John Murdock. Captain Casey and Mr. Dodge are both in Washington, and are known to members. Professor John Murdock at that time had just returned from Point Barrow, Alaska, where he had been spending many months in connection with an expedition under the Signal Service of the Army. He had collected largely both in ethno- logical and zoological lines, and was in Washington working on the report of the expedition. He subsequently became Librarian of the Smithsonian Institution, and is now connected with the Boston Public Library. He attended several of the meetings of the Society. He is a charming man, a delightful talker, graduate of Harvard, and a very well posted zoologist ; in fact he filled the chair of zoology in the University of Wis- consin during the period when Professor Birge was connected with the University of Tokyo. So much for the members present at the first meeting. It will be unnecessary to do anything further in this way of personal description. Reminiscences will come to all of the older mem- bers no doubt after T have finished. On one occasion years ago a member of a prominent north- ern entomological society came to Washington and attended a meeting of our Society. After adjournment I asked him, "Well, what do you think of our society?" "Huh!" he said, 18 PROCEEDINGS ENTOMOLOGICAL SOCIETY "I don't think it is an entomological society at all." "Why?" I asked. "There wasn't a bit of quarreling," he replied. And it is perfectly true that during the whole period of twenty-five years there has not been a trace of hard feeling, of anger, of jealousy, or of scheming for office; though the meetings have frequently been vigorous, they have always been of the most friendly character. As to office, the question has always been, not which of two aspirants to select, but how can we get some good-natured member to accept. This means no depreciation of the honor of office in the Society, but is indicative of the absolutely universal modesty of its members. But this is only one of the good qualities which our Society collectively possesses. That so large a number of our resident members are professional entomologists is a great element of strength. There is nothing amateurish about our meetings and about our published proceedings. An observation brought before one of our meetings meets with a speedy recognition of its true value and its true bearings to a greater degree I think than in any other scientifi: society with which I am familiar. Our progress has been steady and sound. That the same rapid progress will continue through the remaining three-quarters of our first century of existence is almost too much to expect, but it is devoutly to be hoped for. Such a rate of progress for example would give us in the year of our centennial, 1984, an average attendance of 1792, and I doubt whether the hos- pitable successors of the hospitable John Patten will be able to house that gathering. The following papers have been accepted for publication. OF WASHINGTON, VOLUME XI, 1909. 19 NEW SPECIES OF AMERICAN LEPIDOPTERA. BY HARRISON G. DYAR. Family ERYCINID^E.

Hind wing white, finely powdered with fuscous, except on the fringe. Beneath the fore wings are silky blackish, except costa, apex, and discal mark, which are pale. Hind wings silky white. Abdomen shaded with fuscous above. Expanse, 24 mm. One specimen, Tehuacan, Mexico, September, 1908, from Mr. R. Miiller. Type— No. 12221,. U. S. Nat. Mus. , I have placed this species in the genus Centrartha according to Sir G. F. Hampson's sixth volume of the Catalogue Lepi- doptera Phalaenae. It is very close to Chamaeclca gladiola Barnes, described from Arizona, but differs especially in the shape of the discal mark. In gladiola this is large, round and full, while in requies it is less than one-third of the size and roundly triangular. I have at present no specimen of gladiola before me, but shall be surprised if it is not congeneric with requies. This differs conspicuously from Chamaeclea pernana Grote in lacking the frontal process and in having a large claw on the tip of the fore tibia within. Genus STIBADIUM Grote. Stibadium laverna Druce. Thalpochares laverna Druce, Biol. Cent. Am., n, 496, 1898. A specimen before me from Tehuacan, Mexico, agrees with Druce's figure of Thalpochares laverna, except in being darker throughout. The difference is probably due to the freshness of the specimen. It belongs, structurally, to Stibadium, as, indeed, the markings and coloration would suggest. Stibadium psamathochromum, new species. Uniform pale gray, shining, the markings faintly shown ; outer line filiform, strongly angled subcostally ; reniform faintly indicated; sub- terminal line indicated by a pale shade, dentate at veins 3 and 4. Hind wing paler, shining grayish. Expanse, 27 mm. One specimen, Tehuacan, Mexico, from Mr. R. Miiller. Type— No. 12223, U. S. Nat. Mus. The color is paler and grayer than in c.vpallidus Grote, the OF WASHINGTON, VOLUME XI, 1909 23 markings much as in manti Barnes, except that the lines appear dark on a paler ground. Their course, however, is the same. Stibadium crenulosum, new species. Fore wing with the median and terminal spaces blackish brown, extreme base and subtcrminal space light reddish-brown; inner line visible below the cell as long lunules between the veins; outer line crenulate, irregularly doubled ; a few brown streaks in the pale sub- terminal space ; reniform whitish with a curved central dark bar. Hind wing fuscous shaded, especially subterminally, the fringe pale. Expanse, 24 mm. One specimen, Tehuacan, Mexico, September, 1908, from Mr. R. Miiller. Type— No. 12224, U. S. Nat. Mus. The species has the size and aspect of narinni Harvey, but the dark shadings are blacker and not powdery, while the terminal space is sharply discolorous ; the inner line is obscure, but strongly toothed. Stibadium concinnum, new species. Fore wing olivaceous gray, powdery, the ground color lighter along the outer line and around the orbicular ; basal space uniform ; inner line white, narrow, evenly arculate ; orbicular large, round, black-filled, narrowly white-edged ; reniform dark-filled, but scarcely darker than the surrounding area, narrowly white-outlined, constricted ; outer line narrow, white, angled at vein 6, a black costal patch above the angle, subterminal line white, powdery, .with a distinct black inner edge, becoming broader towards the inner margin and obscurely cut by the veins ; fringe with a narrow white line at the base. Hind wing whitish, with a faintly indicated outer line, the terminal space gray-shaded; a grayish discal bar; fringe dark, with a white line at the base. Expanse, 30 mm. Two specimens, Tehuacan, Mexico, September, 1908, from Mr. R. Miiller. Type— No. 12225, U. S. Nat. Mus. The species is allied to curiosnm Neumoegen and pityochro- in us Grote, but is more contrastingly and neatly marked than either. The dark border to the submarginal line is somewhat as in triplagiatus Smith, but more extended and also broken by the veins. Stibadium curiosum Mr. Miiller sends a specimen from Tehuacan, Mexico, darker than the ordinary form. A blackish shading from the base 24 PROCEEDINGS ENTOMOLOGICAL SOCIETY extends nearly to the outer line, obscuring the markings, and the hind wings are nearly solidly blackish. I consider it to be a varietal form. Stibadium jalada Schaus. Collected by Mr. Miiller at Tehuacan, a new locality for the species. Stibadium corazona Schaus. Collected by Air. Miiller at Mexico City. Genus BASILODES Guenee. The following species all have the frontal process with a raised rim and central tubercle. Sir G. F. Hampson defines a genus for them in the seventh volume of the Catalogue Lep- idoptera Phalaenae, but I refrain from using the name, because it appears to be new, and has as yet not been validated by the citation of species under it. Basilodes territans Hy. Edwards! The male specimens before me agree with Doctor Ottolen- gui's figure of the female (Can. Ent., xxx, pi. 5, fig. 4), rather than with his figure of the male. I do not think, however, that there can be two species involved. Basilodes arizona French. I'lusia arizona French, Can. Ent., xxi. 161, 1889 (Sept.). Plusia acantha Druce, Biol. Cent. Am., Lep. Het., 1, 329, 1889 (Nov.) Basilodes arizonac Ottolengui, Can. Ent., xxx, 106, 1898. Basilodes arizonae Dyar, Bull. 52, U. S. Nat. Mus., 196, 1903. French's description agrees entirely with Druce's figure, while the types of both authors were taken by the same collec- tor, presumably in the same locations. A specimen before me from the Schaus collection has the frontal process present, with a raised rim and central cone distinct; in the true Basilodes (chrysopis Grote and pepita Guenee) the central cone is lacking. Basilodes pterochalcea, new species. Fore wing bronzy golden ; costa light purplish-brown, widening over the reniform, which is outlined in brown ; a patch of this color at the base, widening below to the middle of the inner margin; fringe checkered light and dark brown ; a row of brown dots between the veins in subterminnl position. Head and thorax purplish brown. Hind wing grayish, the fringe pale. Expanse, 34 mm. OF WASHINGTON, VOLUME XI, 1909 25 One female, Tehuacan, Mexico, September, 1908, from Mr. R. Miiller. Type— No. 12226, U. S. Nat. Mus. The distribution of golden upon the fore wings is as in Deva ( ?) ornata Ottolengui, but that species has no frontal process. Basilodes chalcotoxum, new species. Dark purplish-gray, irrorated with whitish ; lines obsolete ; a band of bronzy golden from the base of cell curves over at the origin of vein 2 and touches the inner margin beyond the middle, where it is edged with whitish ; outer line faintly indicated in dark, followed by a bronzy luster, which becomes a small bronze patch on veins 6 and 7. Hind wing dark brown, the outer half of the fringe whitish. Expanse, 32 mm One female, Tehuacan, Mexico, September, 1908, from Mr. R. Miiller. Type— No. 12227, U. S. Nat. Mus. The species much resembles Plitsia acema Druce ( Biol. Cent. Am. Lep. Het, i, 330, 1889), described from a single male, but the present species is larger, more slender, while the golden band is narrower and cut in on the outer side at the origin of vein 3. Basilodes chryseochilus, new specks. Head and thorax ochraceous before, dark brown on the disc. Fore wing purplish to the outer line, the terminal space broadly pale golden, with two olhaceous brown-shaded lines; inner line slender, dark, pro- duced into two long teeth, one on the discal and one on the submedian fold; outer line close to the pale margin, slender, dark, arcuate inward below, retracted subapically obliquely to the costa ; median area indis- tinctly streaked with dark purplish; veins finely lined in brown; reni- form ocherous brown, a little lighter than the ground color, without darker edge; fringe' very pale brown. Hind wing blackish, the fringe very pale brown. Expanse, 35 mm. Two females, Tehuacan, Mexico, September, 1908, from Mr. R. Miiller. Type— No. 12228, U. S. Nat. Mus. The form is slender, the fore wings rather long and narrow. Antaplaga subfumosa, new specks. Head and thorax above orange red : abdomen pale gray. Fore wing silky yellowish, with a smoky shading except along the costa and apex, the shading darkest toward base about vein 1. Mind wing pale smoky. 26 PROCEEDINGS ENTOMOLOGICAL SOCIETY darkest costally, the fringe pale. Beneath, fore wing and costal portion of hind whig dark smoky, the rest of the hind wing pale.

Plagiomimicus resoluta, new species. Brownish gray with a pale metallic luster ; lines dark bronzy brown ; inner line slender, bent at right angles on stibmedian fold, else straight and without wavings ; reniform and orbicular outlined in brown, large, slightly paler than the ground ; outer line heavy, straight from inner margin to vein 7 and followed outwardly by a broad pale shade, diffused towards outer margin, the line bent sharply back to costa at vein 7, but the shade continuing more narrowly to apex; subterminal line narrow, faint, pale, crenulate ; a brown line at base of fringe, which is concolorous with the ground color of the wing. Hind wing smoky brown, the veins narrowly darker ; an outer diffused pale band ; a brown line at the base of the fringe, which is dark. Expanse, 32 to 34 mm. Two males, Tehuacan and Guadalajara, Mexico, one from Mr. R. Miiller, the other from the Schaus collection, where it was labeled "Plagiomimicus tepperi Morr." Type— No. 12231, U. S. Nat. Mus. This species does not belong to Plagiomimicus, but, as the name which Sir G. F. Hampson uses for it is at present without included species, 1 refrain from using it. The species has a long claw on the inner side of the fore tibia, the front convex, protuberant, and roughened in a central area with a corneous plate below. Family NOTODONTID^E. Dasylophia roberta, new species. Fore wings light brown, reddish on the costal half, ocherous on the inner half; veins narrowly black; discal mark large, narrowly elliptical ; terminal dots large, powdery, subconfluent ; lines broken and diffused ; subbasal lines single, black, strongly exserted mesially, dentate on the veins ; inner line parallel to the subbasal one, reaching the middle of the cell, single, black, powdery and indistinct, dentate on the veins; (inter line double, represented by two rows of dots on the veins above vein 3, a powdery angulate line below; an obscure oblique brown OF WASHINGTON, VOLUMK XI, 1909. 27 shade line from middle of vein 2 to the outer margin at vein 4.

OF WASHINGTON, VOLUMIi XI, 1909. 31 As above stated, Cule.v pipiens has generally been recognized as the type of the genus, and that no doubt correctly, as this would seem to be the most common, and in a sense, officinal species included, and would thus be intended as the type on Linnaeus' own ideas. Moreover, it is the first species. Of the others, bifnrcatus has been recognized as a mosquito, an Europ- ean species of Anopheles: but very little is said about it, and it was obviously subordinated in Linnaeus' conception of the group. The other species are not mosquitoes at all : pulicaris is a Ceratopogon, re f> tans and eqninns are species of Sitinilinin, and stercorens is apparently some Cyclorhaphid fly. They do not agree with Linnaeus' definition "Os aculeis setaceis intra vaginam flexilem,'' and he could not have had any of them in mind as typical of the genus. The only species so agreeing are the first two, of which the first is much the commoner and better known. We therefore see no reason for attempting to reverse the generally accepted procedure, and would confirm Cule.v pipiens Linnaeus as the type of the genus and family. The next point to be determined is the identity of Cule.v pipiens. Linnaeus obviously intended the term to cover all mosquitoes known to him, directly or indirectly, except the Anopheles, with long palpi in the female, which he separates under the name Cnlc.v bifnrcatus. Linnaeus had experienced mosquitoes in Lapland, and they evidently made a lasting im- pression upon his mind, as he speaks of them as "most abund- ant" and as a terrible plague in that country. He also includes the common domestic forms, as he speaks of their furnishing food to chickens, and he also refers to their occurrence in America and "The Indies," but not by personal observation. The first separation of species from this aggregate was by Linnaeus himself, in the following manner : Previous to the date of the tenth edition of the Systema Naturae, Linnaeus had published Cule.v vulgaris (Act. "Ups., 31, 1736) and Cule.v alpinus (Flor. Lapp., 364, 1737) ; but as these antedate the beginning of zoological nomenclature, they are excluded from consideration. Moreover, Linnaeus himself refers these species as synonyms of pipiens in the second edition of the Fauna Suecica, 1761. However, the descriptions reappear in the second edition of the Flora Lapponica, 1702, so the names may be considered to become valid on that date. Under ordinary conditions, the fact that the names first appeared as synonyms would render their subsequent use inadmissible ; but in Lin- naeus' case we hold that an exception should be made, and the resurrection of the names allowed. Linnaeus first proposed the names to represent valid species, and subsequently referred 32 PROCEEDINGS ENTOMOLOGICAL SOCIETY them to the synonymy. He had clearly the right to again resurrect them. The only reason why he had apparently not that right is because the arbitrarily established beginning of zoological nomenclature, 1758, happened to intervene be- tween the proposal of the names and their reference to the synonymy, which caused their first valid appearance as syn- onyms without accompanying description. We think that in this case the fact of their previous description may justly be considered. Of these species, Cule.v vulgaris is apparently a Simulium, but Cule.v alpinus is a mosquito, and judging from its place of occurrence, an Aedes in the broader sense. This constituted a restriction of the original conception of Cule.v, by the elimina- tion of the Aedes element, the forms abundant in Lapland, and leaves for our consideration only the common domestic species. We exclude also the exotic forms as not personally known to Linnaeus. In this course we follow and confirm the conclusions of F. V. Theobald in his monograph of the mosquitoes of the world, who recognizes as Cule.v pipiens the common domestic mosquito of Europe. Having arrived at this point, we next inquire what is the common domestic mosquito of Europe and does it occur in America? We find in America no less than five closely allied but distinct species living as larvae in artificial accumulations of water and infesting dwellings as adults, which have been known to us collectively as "Cule.v pipiens, the house mosquito." It is probable that there are likewise in Europe several species mixed under the name Cule.v pipiens. Ficalbi (Bull. Soc. Ent. Ital., xxvin, 289, 1896) takes as Cule.v pipiens the common house mosquito of Italy and describes it fully. He had, how- ever, some doubt as to the correctness of his identification and suggests the alternative name Cule.v ha -inatophagus. Now his description indicates that the house mosquito of Italy is not the same species as the one of northern Europe. This latter should clearly be recognized as the true Culex pipiens, while the other may bear the name Cule.v haeinatophagus Ficalbi. It appears to be especially distinguished by the lateral expansion of the abdominal bands on the last two segments, which does not occur in the true Cule.v pipiens, nor in Cule.v fatigans, which Theobald recognizes from the Mediterranean region. It sug- gests in this character the American. Cnle.v siinilis Theobald, an Antillean species resembling the pipiens group. Theobald recognizes that Cnle.v pipiens extends to North America, and IK- separates under the name CnJe.v fatigans the more southerly distributed form, extending through the tropics OF WASHINGTON, VOLUME XI, 1909. of both* the new and old worlds. He does not, however, go into the matter in sufficient detail and his presentation is not con- vincing. We find in the male genitalia excellent characters of specific definition. It is true that Theobald describes these structures, but he has not illustrated with accuracy the basal parts that show the specific distinctions to the best advantage, having confined his attention chiefly to the appendages of the side pieces, which are practically alike in all the species. The exact definition of Culex pipiens, therefore, still remains in some obscurity, and we propose now to resolve it. We would restrict Culex pipiens to that species with the basal clasps of the male genitalia as shown in our figure 4, plate n. We omit the side pieces in our figures as they are alike in all the species referred to. Our specimens are from Copenhagen, Denmark, (Dr. F. Meinert), St-Remy-la-Varenne, Maine et Loire, France (R. du Buysson), and Buda-Pesth, Hungary (Dr. C. Kertesz). We have bred specimens with similar genitalia in America, and are able to confirm the occurrence of the species here, no doubt as an importation. Our common rain-barrel and house mosquitoes comprise the following, as defined by the male genitalia. The adults are generally separable on minor characters of coloration, which we shall describe fully elsewhere ; but the colorational char- acters of these species are unstable and unreliable to a large extent ; neither are the venational differences pointed out by Theobald of any value. Culex pipiens Linnaeus. The harpes (Plate n, fig. 4, a) with a crown of spines as in all the species here discussed, but with rudimentary basal process (fig. 4, b}. Harpagones divided into four plates, the upper one (fig. 4, r ) rather narrow, long, exceeding the tip of the harpes, often bent nearly at right angles near the middle ; second piece (fig. 4, a?) a rather broad plate narrowed at the tip, with a rounded point : third piece a thin, often obscure plate, similar to the second piece but smaller and weaker; fourth piece (fig. 4, /) a broad, concave stout plate with a nar- row rounded tip. The species is especially characterized by having the harpa- gones divided into four plates, all the allied species having at most three. In the lowest forms here shown the harpones are divided into two separate plates, the outer one variously toothed, as in pro.vinius (fig. 6), salinarius (fig. 7), similis fig. 8s), and lachrimans (fig. 9) : next they become divided into three plates, as in rest nans (fig. 5), the second division still 34 PROCEEDINGS ENTOMOLOGICAL SOCIETY toothed, although in a simpler manner ; next there are three divisions, as in quinqucfasciatus (fig. 1), 'coniitatus (fig. 2), and dipscticits (fig. 3), but without teeth, and finally four in pipicns. Moreover the plates are of moderate length, none especially elongated or shortened ; all have rounded pointed tips, without any teeth. We are not sufficiently acquainted with the European fauna to say whether Culc.v pipicns develops local races or allied species in outlying countries adjoining its range, as quinquc- fasciatns and siinilis, hereinafter discussed, do; but such is probably the case. In America it does not, and this furnishes additional support for the opinion that the species has been introduced comparatively recently into America. » Culex quinquefasciatus Say. This seems to be the earliest name for the widely distributed species called Citle.v fatigans by Theobald. We have prepared mounts of the genitalia of specimens from various parts of North and South America, Hawaii, the Philippines, and India, and find them constant. Theobald's distribution for this species is therefore evidently, in the main, correct. His citation of the North American localities which have been given under the name pungens do not show the exact distribution. In general, the "pungens" from northern localities are either pipiens or restuans, those from points south of Washington are quinque- fasciatus', although the ranges of the species overlap to. a certain extent. Just how much we do not know. Specimens from the moist parts of North America, the southern Atlantic States to Mississippi Valley, and from eastern Mexico have genitalia of the normal form (fig. 1), like those of specimens from the West Indies, Guiana, and Brazil, as well as the Philippines and India. In the arid parts of the' United States and the western coast of Mexico a modified form of genitalia is seen (fig. 3), representing a distinct race of the species. We are not acquainted with the line of separation of the forms, as our material is insufficient. Our specimens of the race, for which we propose the name dipscticus, are from Tndio and Coachella, Cal. (in the Salton Sink), La Paz, Baja Cali- fornia, Acapulco and Salina Cruz, Mexico. On the coast of California the species has become modified to a specific degree, and we characterize it here under the name comitatus (fig. 2). In Jamaica we have recognized this species under another name, revocator, because the palpi and the proboscis are more or less distinctly white-tipped. The genitalia arc however, unmodified from the normal quinquefasciatus form, showing OF WASHINGTON, VOLUME XI, 1909 35 that the species is but narrowly separated from quinquefas- ciatus, if, indeed, it is a true species at all. In the genitalia of the typical form (Plate i, fig. 1) the harpes have a small basal projection, larger than in pipiens, but still in a rudimentary condition. The harpagones are divided into three plates ; the second (fig. 1, c) is a rather slender plate about as long as the harpes, with rounded pointed tip ; first plate (fig. 1, d} broad, very long, with bluntly rounded tip; third plate (fig. 1, /) essentially as in pipiens. The species is especially characterized by the great length of the central plate of the harpagones, which is not divided into two portions, as in pipiens. In the genitalia of the race dipseticus (fig. 3), the first branch of the harpagones is not especially elongated (fig. 3, c). The other characters remain essentially the same, including the flat and pointed condition of the second plate (fig. 3, d). Type— No. of the race dipseticus, 12229, U. S. Nat. Mus. Culex comitatus, new species. The genitalia (Plate i, fig. 2) have the general characters of quinquefasciatus, race dipseticus, but differ especially in the character of the second plate of the harpagones (fig. 2, d}, which is no longer a plate, but a -tubular structure, with oblique open tip. The first plate of the harpagones is broad and rather long, with rounded tip, essentially as in dipseticus. The basal projection of the harpes is very short, but this cannot be espec- ially emphasized, as its apparent condition varies greatly with the position of the mount. Our specimens are from National City, San Diego, Sweet- water Junction, Laguna, Avalon, Los Angeles, San Pedro, San Luis Obispo, and Stanford University, California, all these places being on the coast, south of San Francisco, or on the adjacent islands. It is somewhat curious that the species Culex quinqucfas- ciatus, after ranging throughout the warmer parts of the world unchanged, should, in the arid parts of America, develop first a distinct race and finally a species. This must be of significance in regard to the original home of the species. Evidently quin- quefasciatus is of tropical American origin, and has latterly spread, no doubt through the agency of commerce, to all the warmer regions of the world. In these places it has not been resident long enough to develop local races and species, as it has done in America. Conversely, it is probably that Culex pipiens is of European origin, and has only latterly spread to America through the agency of commerce, 36 PROCEEDINGS ENTOMOLOGICAL SOCIETY Culc.v comitatus has the same habits as its congener, quin- quefasciatus. The larvse occur in all sorts of artificial accum- ulations of water, and the adults frequent houses and attack the inmates at night. Type— No. 12201, U. S. Nat. Mus. Culex restuans Theobald. The genitalia (fig. 5) have the harpes with a distinct, though short hasal projection (fig. 5, &). Harpagones divided into three plates; first plate (fig. 5, c) narrow, rather short, with rounded pointed tips ; second plate broad, short, the tip broadly rounded, with small reversed teeth near the middle and a large, sharp, angular spine projecting outward from near the base; third plate (fig. 5, /) essentially as in pipiens, but shown fore- shortened from side view in the figure. The genitalia agree with those of quinquefasciatus in the number of divisions of the harpagones, but are readily distin- guished by the peculiar form of the second division, with its large lateral tooth. This species agrees with the foregoing ones in the vestiture of the mesonotum, which consists of the ordinary narrow, curved scales, which cover the surface rather completely. In all of the following the vestiture is of minute, hair-like scales, not covering the surface. The dentation of second division of the harpagones allies the species with the next group, typified by Culex similis Theobald. This species, therefore, stands by itself, allied to both the pipiens and similis groups, but more closely to the former. Culex salinarius Coquillett. The genitalia (Plate in, fig. 7) have the harpes with a long curved arm from the outer base (fig. 7, b}. Harpagones divided into two plates ; the outer one (fig. 7, d} a broad plate with a series of long teeth, which lie nearly in a plane, a large tooth above, partly separated, and an upcurved one below are separated by a row of smaller, more even teeth ; inner plate concave, tapering to a rounded tip (fig. 7, /). The species is especially characterized by the absence of the long lateral tooth of the outer plate of the harpagones, which is present in the two following species. This species, together with the following ones, similis Theo- bald, factor Dyar and Knab, and pro.vimus Dyar and Knab, form a distinct group, separate from the pipiens group. We should not discuss them in this connection, except that the simi- larity of coloration of the adults has led to confusion. The OF WASHINGTON, VOI.UMK XI, 1909 37 vestiture of the mesonotum is distinctly different in this group from that of the foregoing f>if>icns group, and serves readily to distinguish them, without the criterion of the male genitalia. Culc.r salinarins is a close ally of siniilis Theobald, and may be considered to take its place in North America. Culex siniilis inhabits the Antilles, while salinarins is found throughout the eastern part of North America, from Maine to Florida and westward to the Mississippi \ alley. The two species are doubt- less derived from a common American stock, but have been long separated, and have developed well-marked specific characters. Cnlc.v factor represents these species along the Pacific coast of .Mexico and Central America. Culex factor Dyar and Knab. In this species, which we have not figured, the genitalia are ot the type seen in salinarius and siniilis. The outer plate of the harpagones has above a large tooth, followed by three slender, well-separated ones below, the lower angle forming a large rounded angle, too large and broad to be described as a tooth; a long horn-like tooth arises in a different plane, and exceeds the other teeth in length. The lower plate of the harpa- gones is of the usual form. The harpes have the erect portion crowned with' spines as usual, the basal projection very long and curved, as in our figure of salinarius (fig. 7, b}. The species is especially characterized by the fewness of the central teeth of the outer plate of the harpagones, and the long horn-like tooth, which exceeds the other teeth in length. The scales of the mesonotum are hair-like and sparse, but they are larger and coarser than those of salinarius and siniilis. The species inhabits the west coast of Mexico and Central America, seeming especially at home in salt water. Most of our specimens were bred at Salina Cruz, Mexico, from salt pools behind the beach, and Mr. Jennings has obtained the species in the La Hoca swamp in the Canal Zone, Panama, which is a low swamp on the Pacific side of the Isthmus. We have also speci- mens from Tehuantepec and Santa Lucrecia, Mexico, bred from fresh water, showing that the species is not confined to salt water. It is evidently much like our salinarius, which is most abundant near salt marshes, although generally distributed throughout the country, but perhaps this is more addicted to actually salt water than salinarius is. Culex similis Theobald. The genitalia (Plate in, fig. 8) have the harpagones and harpes essentially as in salinarius, but are especially distin- 38 PROCEEDINGS ENTOMOLOGICAL SOCIETY guished therefrom by the long lateral tooth of the harpagones (fig. 8, c), which arises in a different plane from the other teeth. This species ranges throughout the Antilles; we distin- guish the form occurring upon the mainland in the Guianas under the name lachrimans. This is probably not more than a geographical race, yet the genitalia (fig. 9) apparently differ in the shape and proportions of the teeth of the harpagones. These apparently differ in different slides, owing to the position of the parts, and too much stress should not be laid upon these apparent differences. Nevertheless, there are no doubt some actual differences, and the race is a good one, as we note cer- tain slight differences in the coloration of the adults. The name lachrimans wras proposed by us (Smiths. Misc. Colls., quart, iss., LIT, 259, 1909) as a substitute for Culex aikenii Dyar and Knab (Proc. U. S. Nat. Mus., xxxv, 61, 1908, which was preoccupied by Gnophodeomyia aikenii Aiken (Brit. Guian. Med. Ann., 1906, 60, 1907), since Gnophodeomyia falls as a synomym of Culex. The name Culex lachrimans was founded upon adults and larvae. It has since transpired that there was a mixture of material, the adults being Culc.v quinquefasciatus, the larvae Culex similis. We have concluded to restrict the name lachrimans to the larvae, and it will thus stand for the local race of similis inhabiting the Guianas. Culex proximus, new species. The genitalia (Plate u, fig. 6) have the basal projection of the harpes (fig. 6, b) long and curved. Harpagones divided into two plates, the upper one very irregularly shaped and toothed, a large blunt tooth at the bottom, long and curved, a similar but shorter one at the top with a group of smaller ones between; a long sharp tooth arising in a different plane from the others (fig. 6, e) and exceeding any of them in length ; lower plate concave, broad, with narrowed rounded tip (fig. 6, /). The plate is shown fully extended in the figure and appears very broad in comparison with some of the other figures, for example rcstiians (fig. 5, /), but this difference is due to the position of the parts in the slide. The species is especially distinguished by the length of the lateral tooth of the harpagones (fig. 6, r— No. 12239, U. S. Nat.

In the summer of 1907, while engaged in collecting para- sited Rhyncophora for the Cotton-Boll Weevil Investigations, I collected a large number of seed pods of Cassia chamcechrista at Marr's Station, Md., infested with a then unknown cur- culionid larva. Part of this material was preserved and sent to Air. Pierce for discription, the remainder was placed in rear- ing jars on the day of collection, September 17, and observed from day to day until October 1, when I was called away from this city. But no pupse were found. On leaving Washington this material was handed over to Dr. F. H. Chittenden, of the Bureau of Entomology, who sent me the following note some time later : Chalcodermus collaris issued from the cassia seed pods you left with me. They started to emerge October 4 and continued to appear until October 8. Though this observation does not determine the length of the pupal stage of this insect, I give it as a guide to future observation. THE COPULATING AND FEEDING HABITS OF IDIAR- THRON ATRISPINUSSTAL. [Orthoptera, Locustidae.] BY A. N. CAUDELL. From a translation of a letter from A. Tonduz of San Jose, Costa Rica, which was kindly furnished by Prof. H. Pittier, I quote the following paragraph : One day I observed two of my crickets ( Idhtrthron utrispiniis) copu- lating and after separating the female had two white gobular masses attached to her posterior; she then bent down so as to tear this white mass with her mandibles. I observed the same act with another subject and upon another occasion. The above indicates that the ejection of the sperm mass by the male in the form of a bilobate seminal sac ( the two masses mentioned in the above extract being very surely the two lobes of a single sac) is not confined to Anabrns and Pcranabnts as recorded by Gillette,* and Snodgrass,f and long before by *Ent. News, vol. xv, p. 321-324, pi. xix (1904). tjourn. N. Y. Ent. Soc., vol. xm, p. 79-80 (1905). OF WASHINGTON, VOLTMK XI, 1909, 41 Feilner.* When more is known of the mating habits of Or- thoptera this will very likely be found to be quite common, at least in the Locustid;e. It has now been noted in .Inahrns, Peranabrns, Scitdderia,^ and Idiathron, and I have seen much a sac in a cabinet specimen of a species of Orophus. [dlarthron atrispinns is an important enemy to the coffee plant according to the letter mentioned above. Last year was the first time the writer noted damage done by this insect. Its ravages probably commenced in late August or early Septem- ber. During the day the insects hide in the dry or damp sheaths of the banana plant and probably in other lurking places of like nature. In the Museum Gardens at San Jose the two or three coffee trees had all their leaves pierced and an immense number of their berries peeled and sometimes entirely hollowed, out by the bites of the insects. The crickets hide here during the day in the petiole grooves of a large perfoliate-leaved tree or under old manure sacks spread on the ground, but in coffee plantations their chief refuge is probably the banana. It is very hard, in fact almost impossible, to discover one of the insects in a coffee tree during the day, which fact delayed for some time the discovery of the real culprit. The nature of the injury indicated some strong-jawed depredator, and as this insect was very plentiful in the neighborhood it was sus- pected. Specimens placed in a jar with intact leaves and berries of the coffee tree established their guilt beyond question by producing exactly the same injuries as found on trees in the open. *Rept.

Harrisburg, Pa., July 27, August 2 (D. K. McMillan) ; June 14, 1908 (P. H. Hertzog). Chelonus carpocapsae, new species. This species is very like C. fissus, from which species as well as all other species of Chelonus it can readily be separated by the structure of the metathorax, which along the outer and upper edge of the posterior face is produced into four nearly equidistant prolongations that are nipple-shaped in outline, the productions nearest the middle line are farther from each other than from the outermost productions. This structure of the metathorax calls to mind the structure of the apical margin of the abdomen in Chrysis (Tetrachrysis) nitidula, though the productions are by no means thinned out or pointed in this case as in the foregoing species; scape and basal third of flagel brownish, basal half of posterior tibiae mostly brownish, the apical half almost black.

This is apparently the only species of Paratiphia in the east- ern part of the United States. According to present knowledge it seems to be confined to the State of New Jersey. This form has been erroneously determined as P. albilabris Spinola, which latter has hyaline wings and hails from California. From P. clypeata Smith, formerly Tiphia, P. varipunctata Cameron, P. fuscipennis Cam., P. robusta Cam. and P. fuscinerva Cam., this species is readily separated by the nonconcolorous wings. From P. dnodeccini/iaculata Cam. by the immaculate abdomen. Male 8 mm. long. Xearly all of the tegument shining black, punctate, with the punctures ranging from adjoining to at least as far as three puncture-widths apart, bedecked with silvery pubescence that nowhere is so thick as to obscure the tegument and is made up of hairs the longest of which are shorter than the 13th joint of the antennas, the hairs also much thinner than the thinnest vein in the wings. Head a little wider than long ; eyes diverging above ; converging below; malar space practically wanting: if straight lines were drawn connecting the centers of the ocelli an obtuse-angled triangle would be formed, shortest distance between the posterior ocelli apparently equal to the shortest distance between the lateral ocellus and the nearest eye margin; clypeus about twice as wide as long, yellow, with rather distinct punctures from one to several puncture-widths apart, its anter- ior margin seemingly depressed somewhat arcuately, convexly rounded; mandibles falcate, rounded off at tips, with a rounded angle or vestigial tooth on the inner margin near the apex, mostly yellow aJiove, brownish at apex; antenn;e nearly of the same diameter throughout, the pedicel distinctly narrower than the -cape or the first joint of the flagel, scape rather oviform, equal in length to the length of the pedicel and the first and second joints of the flagel combined, first and second joints of flagel subequal in length, wider than long, the succeeding joints longer than wide but only slightlj so or not much lon»vr than wide, with the exception of the apical joint, which is easily twice longer than wide. Metathorax with a superior and posterior aspect in addition to its sides, 46 PROCEEDINGS ENTOMOLOGICAL SOCIETY the posterior aspect rugosopunctate or nearly and separated from the superior aspect by a convex ridge which is not sharp and with a low rather angular prominence on each lateral edge in the middle, the superior aspect rather irregularly coarsely sculptured with a rather distinct median, longitudinal, rounded off, low carina, sides of meta- thorax with transverse striae, each stria being nearly as coarse as the longitudinal carina on the superior aspect ; wings hyaline, excepting the stigma and veins, which are dark brown, and a stain occupying the greater portion of the apical half of the wing, which is brown, hirsute, with shorter hairs than on the body; the hairs are also of a different kind and dark. Abdomen with a distinct anterior aspect to the first dorsal segment, separated from the dorsal aspect by a transverse, curved carina ; segments along the apical margin with a fringe made up of apparently single and rather appressed hairs ; pygidium bounded on each side and apically by a rather distinct carina.

The type female and male and three paratopotypes were submitted to the writer for determination by Prof. John B. Smith. Another specimen, a paratype, was collected by Mr. V. A. E. Daecke at Brown's Mills Junction July 21, 1907. Female 6.5 mm. Differs from the description of the male as follows : Longest hairs seemingly shorter than the twelfth joint of the Mitenme. Head, shortest distance between posterior ocelli somewhr.t shorter than the distance between lateral ocellus and nearest eye margin, clypeus black ; mandibles with hardly a rounded angle on the inner edge, castaneous throughout, pedical as wide and about as long as the first joint of the flagel scape easily twice as long as -its greatest width or about equal to tht combined length of the pedicel and first and second joints of the flagel, most of the joints of the flagel subequal and wider than long. Superior aspect of metathorax with a triangular enclosure formed by two oblique lateral lines, the enclosure bisected by a longitudinal raised line ; wings with the apical fourth and greater part of the third fourth brownish, the brownish portion streaked with .faint hyaline lines. At least the apical half of pygidium with adjoining punctures, except- ing the pygidium the apical dorsal segment of the abdomen is rugose or recticulate rugose. Female paratype from Lahaway, N.

On account of its two submarginal cells, etc., this might be relegated to a relationship with Rhophitbides Schenck. It is however more likely, judging from its habitus, that this genus is nearer Noinia and really an Andrenid with only two sub- marginal cells, the first nearly one and a half times as long as tbe second on the cubital vein.

[Coleoptera, Eucnemidas.j (Plate IV.) BY R. W. VAN HORN. The object of this paper is to record some observations on the habits and life history of a family of Coleoptera that here- tofore has been somewhat neglected by American entomolo- gists. The writer wishes to acknowledge himself indebted to Mr. E. A. Schwarz for the identification of some of the adult beetles, and to Dr. A. D. Hopkins for suggestions in preparing this paper for publication. The obser- vations were made by the writer whilst employed in the Branch of Forest Insect Investigations, Bu- reau of Entomology. One of the parasites of these beetles is of some interest, as it proves to be not only a new species, but also appears to represent a new family of the Hymenoptera. Species of the family Eucnemidse, especially in their larval state, are not only of scientific interest on account of their appearance, but several may prove of some eco- nomic interest as well. Their oc- currence in the East, with the ex- ception of two or three species, may be considered rare, though the difficulty of collecting specimens may account in some measure for the obscurity in which their life history has been shrouded. Unless the collector is some- what familiar with their mines and the condition and identity of the host plants, the insects will generally be overlooked. It is not possible at the present time to take up the family in specific order, so that the object is more to give a general description of the character of the galleries, the appearance and habits of some of the most characteristic species, the host plants, and the conditions under which the insects live and undergo their trans- formations. FIG. 3.— Adult male of Tharops ruficornis Say. OF WASHINGTON, VOLUME XI, 1909 55 Observations made thus far indicate that among the species which infest deciduous trees there are two distinct groups, viz, those that bore in the hard, solid wood, and others which live in the softer decaying wood. Besides these there are a small number of species, comprising about four genera, that have been collected from under the bark of dying and dead coniferous trees. Mr. H. E. Burke, of the Bureau of Entomol- ogy, collected a number of adult specimens of Melasis rufipen- nis in Abies concolor. He found that they had bored through the bark and to a distance of 2 or 3 inches into the solid wood of a dying tree. Whether this was for the purpose of oviposit- ing or merely to obtain food it is impossible to say. Deltometopus has been found beneath the bark of Pinus virginiana, and Epiphanis and .Inalastes in the adult form under dead bark of dif- ferent coniferous trees. There is no record of the larvae of any of these species having been col- lected, and no observa- tions have been made on their life history. Of the eastern species which live in sound, hard wood, there are only about three known genera, two of which at- tack practically all hard, fine-grained wood, pre- ferably the maple. The most common of these is Melasis pectinicornis. While these species normally infest the sound wood, they are sometimes found in slightly decaying wood, as under damp conditions the wood will often begin to decay before the brood has emerged. Species of the genera Thar ops and Melasis make transverse galleries extending directly across the grain of the wood in more or less of a semicircle, though seldom, if ever, extending entirely around. Such a gallery once recog- nized could not be mistaken for any other. A specimen of the work of Thar ops ruficornis in Cornus florida, collected at Virginia Beach, Va. (fig. 4). showed that the larvae had completely severed the trunk almost as neatly as if done by a saw, though not as regularly, as it required nearly a FIG. 4. — Work of Tharops rujlcornis larvae in Cornus florida. 56 PROCEEDINGS ENTOMOLOGICAL SOCIETY dozen larvae to accomplish the feat. This presents an economic side, as this beetle, when numerous, as it sometimes is in hard- wood forests along the coast and along the border of streams, is quite capable of doing considerable damage to timber. It makes a broad gallery, extending deep into the wood, yet so shallow as often to escape notice unless the beetle has emerged, when a small round hole will be seen. Although species of these genera seemingly prefer lowlands along waterways they are also found at considerable elevation, infesting all fine-grained hard-woods. In these Mclasis pcctlni- cornis and Thar ops sp. are often found closely associated and with intermingling mines. They are also found closely asso- ciated with a number of Cerambycid, Buprestid, and Ptinid larvae, particularly a small Ptilimis sp. ; all seem to dwell together in perfect harmony. One characteristic of this group of borers in sound wood, and one which is rather unusual in coleopterous larva?, is the fact that at no time can any trace of ejected borings be found around the host plant. They seem to work in complete secrecy, the borings being packed behind the larva as it cuts its way through the wood, and the mine always is wide enough for it to turn around. The larvae of this family are very sluggish in their move- ments, and when taken from their mines seem incapable of any movement beyond the bending of the body from side to side. There is no record of any species of these beetles having been observed in the act of ovipositing, but from the appearance of the ovipositor it is probable that the eggs are placed in the cracks and crevices of the bark, after the manner of the Cerambycidae and Buprestidae, where they hatch and the young larvae work their way directly into the wood. They then mine through the sapwood and (unless the tree is exceptionally large) into the heartwood, where they attain their full development or nearly so ; they then work their way into the sapwood again and excavate the pupal cell from 0.25 to 1 inch from the surface, directly across the grain of the wood. After completing its cell, the larva makes a small round exit hole to within a hair's breadth of the surface for the emergence of the young imago. While the larva is making its pupal cell it is in a looped or doubled-up position, as some species of the Buprestidae are often found, especially Agrilus. It is doubtful whether the larvae are in this position at the time of their pupation, as it would seem that the muscles of the body should be straight at this time, or nearly so. There seems to be no regular time for the general emergence of the images, this period ranging from May to August inclusive, though OF WASHINGTON, VOLUME XI, 1909. 57 probably more emerge during the month of June than at any oilier time. From present indications the immature stages last from ten to fifteen or even eighteen months, according to the favorable or unfavorable conditions prevailing. The more advanced larvae attain their full growth by the latter part of the fall, sonic transforming to adults and remaining dormant in their pupal cells throughout the winter, while others, quite often of the same brood, overwinter in the larval form. The pupal stage is very short, lasting but a few days. There is no record of their overwintering in this stage. The other genus of this group infesting sound wood is \ cina tod cs. Species of this genus make an entirely different mine from the two previously mentioned ones. Instead of the broad, flat, transverse mine these larvae excavate an oval or nearly round mine, just large enough for the passage of the larva ; it extends in a general parallel direction with the grain of the wood, though winding in and out, and in some instances it is found_ to have turned entirely around. The pupal cell is made in the same parallel way. In this instance there is no exit hole made by the larva, for it pupates close to the surface of the wood and as the adult possesses large, strong mandibles it is no great task for it to make its escape. This insect seems to require damp conditions for its development, just opposite from the condition which is normally preferred by species of Melasis and Tharops. The galleries are usually discolored by a bluish fungous growth, and near the surface or beginning the gallery will often appear to be sap-stained, which would indicate that the larva had been at work in its host before the sap had en- tirely dried up. The life history of species of this genus has not been satisfactorily worked out and the period of time required for the development of the insect is not known. Contrary in habit to the other two genera, this insect seems to be partial to the coarse-grained woods of different species of oak. A black oak sapling at Lynnhaven, Va., was found thick- ly infested near the base by Nematodes atropos larvae, pupae, and young imagos on June 15. Some of the beetles were then beginning to emerge. Most of the mines appeared to be only 5 or (> inches in length ; they arc. however, very difficult to trace to their source and many of them are doubtless longer. Species of this genus are very rare, and even if abundant would pre- .sumably be of little economic importance, as the small parallel mines would be less injurious to timber than the broad trans- verse mines of Melasis and Tharops. Although no known larv;e of this family possess lep-s, as do those of the true Elat- crids, there is in the larva of Ncinatodes atropos a chitinous 58 PROCEEDINGS ENTOMOLOGICAL SOCIETY prosternal plate projecting slightly beyond the line of the body and ending in two short but sharp hooks which no doubt aid the larva in its movements. Not the least striking larval char- acter of this family is the unusual shape of the mandibles, which depart from the general rule of all known coleopterous larvae by curving outward. This character has held good in all species examined by the writer. The muscles are attached to the mandibles in such a manner that when they contract, instead of bringing the edges together they throw them apart. Instead of biting or pinching the wood the mandibles act as miniature rasps or saws. This, as can be seen from the broad galleries of Tharops and Melasis, would be more useful to the larvae than the usually fashioned ones. This theory of the movement of the mandibles was substantiated by the writer by observing through a microscope a larva of Melasis pectini- cornis at work in its gallery. During the transformation of the larva to pupa the mandibles change their form and position and the adult possesses mandibles similar in general shape to those of other beetles. The adults of the borers in sound wood pos- sess very powerful mandibles and in Ncmatodes they overlap. Species that infest decaying wood are represented by only two genera, namely, Fornax and Microrrhagus. The form of the gallery and condition of the wood in which the larvae of these genera live are very similar, except that Fornax has a relatively larger mine. It has been suggested that the larvae of these two genera make no definite gallery but simply push their way through the soft wood, which closes behind them and leaves no trace of their passage. While it is usually impos- sible to trace a gallery its entire length, yet when the wood is not in too far advanced a state of decay they are clearly visible and may be seen curving about in the wood, running in a longi- tudinal direction, then turning in a transverse one. There is an abundance of evidence that the larvae not only make galleries in decayed wood but that they also occasionally mine in solid wood. As an example of this the writer found a large dead willow thickly infested with Forna.v badius larvae, several of which had bored through the soft sapwood to a distance of 3 or 4 inches into the solid heartwood. The mines of species of this group are relatively small and more open than those of the opposite one. The difference in size may be accounted for by the fact that the wood is softer and more elastic than solid wood, giving it a tendency to close behind the larva, thus reducing the diameter of the mine and the soft, damp state of the wood causing the borings to pack and adhere more readily to the sides of the gallery. OF WASHINGTON, VOLUME xi, 1909. 59 The larvae of this group usually make their pupal cells deep in the sapwood. While making these cells they assume the looped position similar to those of the opposite group. To determine whether these larvae would pupate in this position, two full-grown larvae of Fornax badins were taken from their pupal cells and placed in similar shaped ones made with a knife in Liriodcndron (the host from which they were taken), one in a straight position and the other in a hooked one, and the latter was observed to change its position to a straight one before pupating. This species has been reared to the adult stage during the first week in June. All present observations indicate that there is but one generation a year, the immature stages lasting from ten to twelve months. The mouthparts of the larvae of this group are quite micro- scopic, and when viewed through an ordinary hand lens the head appears perfectly solid, and the mandibles, surrounded as they are by twelve other saw-like teeth, seem to be immov- able fixtures. The larvae of this group apparently employ a different method in excavating their galleries from those of the opposite one. Instead of depending entirely upon their mandi- bles, which are comparatively small and feeble, these larvae utilize the chitinized teeth with which the head is armed, the head being connected with the thorax in a manner somewhat corresponding to the ball and socket joint of vertebrate animals. This enables the larva to move its head freely and in any direction, and also gives it additional strength. Assisted by the powerful muscles of the body and the hardened, chitinized body-wall, it is capable of sawing even into solid wood. No parasites have thus far been bred from species of these genera. The borers, in decayed wood are harder bodied and more chitinous than those of the opposite group. They also possess much smaller mouthparts, the mandibles being much shorter, but having the same outward curve. On the ventral side of the last segment is a shallow, spoon-shaped depression, chitin- ous and roughened around its border and finely punctured in the center. The body is of a uniform shining straw-color, with dark brown markings on the thorax and head and dark brown mandibles and caudal end. All the larvae of both groups possess nine pairs of spiracles. In the borers of solid wood, with the exception of Nematodes, the body is softer, less chitinous, and lighter in color. In Melasis'and Tharops the full-grown larvae are usually trans- lucent or wax-color, with head and mandibles dark brown. In the larvae of these genera there are a pair of slightly raised chitinous T-shaped markings on both the dorsal and ventral 60 PROCEEDINGS ENTOMOLOGICAL SOCIETY sides of the prothorax. These stripes in the full-grown larva usually change on the ventral side to an inverted |_ , owing to a shortening and rounding-out process which then takes place, causing the segments to overlap slightly. In Nematodes the abdominal segments are longer and more rounded and each segment appears to be composed of two. The body is also darker in color and more chitinous. The larvae of this genus may readily be recognized by the presence of two sternal pro- cesses or hooks on the prothoracic segment. The last segment is dilated, chitinized, with a concave ventral depression. Species of Melasis and Tharops possess this concave depression on the ventral side of the last segment, but it is not chitinized nor dilated. The crops of two typical representatives of these respective groups were examined under a compound micro- scope. That of Mclosis pectinicornis contained nothing but minute fragments of wood fiber, and that of Fornax badius only liquid which may have been extracted from the damp wood in which they live. This comparatively small family of beetles, which has been recognized by many writers as distinct, has been placed by LeConte and Horn, in their classification of Coleoptera, published in 1883, as a subfamily at the head of the Elateridse. The only character separating them from the true Elaterids is found in the insertion of the antennas at the extreme front. The clicking apparatus is present, but usually undeveloped, so that it is impossible for the beetle to hop into the air. According to information from Mr. Schwarz, there is a small species of Deltomctopus which is capable of making a feeble leap, but Doctor Horn doubts the position of this genus in the Eucnemidse. The eucnemids possess much better characters in the larval form than in the adult. Perhaps one of the best characters for separating them from the Elaterids is the absence of legs or feet in the larvae. The habits and life history of most of the species are also widely different from those of the true Elaterids. In their immature stage they ap- proach much nearer several genera in the Buprestidse, particu- larly Agrilus. While the writer has frequently found the larvae closely associated with other coleopterous and hymenopterous larvae, he has seen no evidence of their possessing predatory habits.

Dr. Hopkins, in discussing the paper, stated that in a number of respects it was quite remarkable. It relates to a group of beetles to which considerable attention has been attracted by some of the leading coleopterists of Europe and this country; yet very little was known about the different stages and habits of the species. Therefore the amount of original information on tlicsc insects secured by Mr. Van Horn, conveyed in this 62 PROCEEDINGS ENTOMOLOGICAL SOCIETY paper, and recorded in his notes, is worthy of the highest com- mendation. When we consider that only a little more than two years ago, December, 1906, he knew practically nothing about insects and that his education was limited to the country schools, his accomplishment in this, as well as his general rapid progress, was nothing less than phenomenal. His work on the eucnemicl beetles was almost entirely on his own initiative and carried on in addition to his regular duties as preparator in Dr. Hopkins's office. He was inspired, perhaps, by finding a curious larva while on an excursion to Great Falls, on December 31, 1907, which attracted much attention; no one in the Museum or the Bureau of Entomology could identify it beyond the family it represented. Evidently he determined that he would find out for himself, which he did, and thus demon- strated that he was endowed with the true spirit of the so- called old-fashioned naturalists, who, through their love for nature, and natural ability to see and do things, succeeded in spite of many disadvantages and apparently insurmountable obstacles. The last time we saw Mr. Van Horn at the office was on February 4, 1909. On February 9, following a temporary illness, on leaving his home with a bundle under his arm, he remarked to his mother that he was going to the laundry. This is the last that has been heard of him. Dr. Hopkins concluded his remarks with the statement that he felt very deep- ly this apparent unhappy ending of such a promising career, mainly on account of the great need of men of his character and ability to assist in the present work on forest insects, take charge of important lines of investigations, and continue the efforts to advance the science of forest entomology as the older workers drop out. Mr. Schwarz is in full accord with those authors who con- sider the Eucnemidas as a family distinct from the Elateridae. It is to be regretted that the early stages of some of the out- lying genera, as Perothops and others, are still unknown. —Mr. Crawford next discussed the remarkable parasite reared from these beetles by Mr. Van Horn in a paper entitled : OF WASHINGTON, VOLUME XI, 1909 63 A NEW FAMILY OF PARASITIC HYMENOPTERA.

Professor Webster read the fol- lowing paper : HOW LYSIPHLEBUS FASTENS ITS APHID HOST TO THE PLANT. [Hymenoptera, Braconidae.] BY E. O. G. KELLY. During the fall of 1908, in connection with his investigations of Toxoptera graminum, the writer carefully bred and reared several hundred parasites belonging to the genus Lysiphlebus Foerster. In order that some careful interbreeding could be done, individual aphids, upon turning brown (caused by the para- sites), were removed from the host plant to small homeopathic vials stoppered with cotton, in which the adult Lysiphlebus emerged. In removing these brown aphids from the plant they were observed to be securely fastened to it by silken threads enmassecl in a glutinous substance which had become dry and hard. The glutinous substance and silk are more or less brittle and numbers of cocoons (as they really are cocoons) were broken open on the ventral side at the point of attach- ment, while being removed from the plant. The breaking open of the cocoon was nearly always fatal to the parasite, in fact, it proved to be inconveniently so; consequently another PHOC. ENT. SOC. WASHINGTON. VOLUME XI. PLATE V VANHORNIA EUCNEMIDARUM CRAWFORD OF WASHINGTON, VOLUME XI, 1909 (,5 method for removing the parasitized aphids was adopted— that of cutting off the inhabited portion of the plant without molesting the aphid skin or enclosed parasite. hi order to study the development of the Lysiphlebus larva after the skin of the aphid turns brown, full-grown aphids containing a full-grown Lysiphlebus larva were placed on glass slides with the ventral side next to the slide. For a short time before death, and four to six hours after death of the para- sitized aphid, the yellowish parasitic larva can be seen through the thin semitransparent skin of the host; thus the revolutions of the parasitic larva, while shaping the aphid body into tin; globular form as observed by Professor Webster (Proceedings Ent. Soc. Washington, vol. ix. p. 110), can be seen until the skin begins to change its color. The aphid becomes very feeble just before death, but tenaciously grasps the leaf and dies thereon with a rigid death grip. This tends to hold it to the leaf temporarily while the parasitic larva is shaping the host body into a globular form. When the parasitic larva finishes shaping and partially drying the aphid skin it pushes its head through the ventral side, and, by working its body into the opening, makes a slit the entire length of the abdomen, and by pushing, twisting, and revolving converts it into an irregular oval-shaped opening. It then begins to fasten the aphid to t he- leaf or other object upon which the host insect happened to make its last stand, by spinning silken threads and spitting out a glutinous fluid, attaching one end of the thread to the leaf or other object, and the other to the inside wall of the aphid skin. The larva moves its head back and forth from leaf to aphid, progressing forward with each stroke, thus forming a zigzag strand of silk around and around the opening until the aphid skin is made fast. The larva continues spinning and shaping a cocoon on the inside wall of the aphid skin for 20 to 26 hours, when the cocoon is finished. The silken film formed over the ventral opening is not transparent or but faintly so in speci- mens removed from plants, but it is quite transparent when attached to the glass slide and by careful focusing and adjust- ment of light the insect can be readily observed. After finishing the cocoon, the larva folds itself and becomes quiet ; wing pads, legs, and antenna? become apparent in 60 to 75 hours from the time the larva began making its cocoon; it changes color from yellow to black in 100 to 120 hours, and becomes adult in 7 to 8 days (the length of these different stages depends upon the temperature I. 66 PROCEEDINGS ENTOMOLOGICAL SOCIETY The larva spins a silken cocoon, attaching it to inside wall of the aphid, leaving it entire ; it does not make any opening in the cocoon nor cnt away any of the aphid wall. When the insect becomes fully developed it kicks and pushes about until it frees itself from the pupal envelope and then begins to use its mandibles freely upon the silk of the cocoon; in three to five hours it cuts out a disc of the aphid skin and crawls out ready to fly away. The adult is not only ready to fly away, but is also ready to begin reproducing its kind. Virgin females began ovipositing within four minutes after escaping from the cocoon ; another mated to a male within less than one minute; this latter ovi- posited in To.voptera graminum within five minutes, from which adult Lysiphlebus were afterwards reared. —Mr. Gahan gave some remarks on the rearing of parasites from the nests of Thyridopteryx ephctneraeformis and men- tioned finding Dicymolomia julianalis feeding on the eggs. The previous records found by Mr. Gahan were from cat-tail heads. One of the parasites, Leucodesmia typica How., was reared for the first time since the original material on which the species was based. Mr. Quaintance said that about a year ago he and Mr. Jones had reared D. julianalis from the same source and on looking up the literature found it recorded years ago by Professor Riley. Dr. Dyar was of the opinion that this species was a scaven- ger looking for insect remains and that their eating of the eggs was accidental. Specimens in the National Museum have been bred from the heads of Typlia and from cotton bolls, where they were probably scavengers. —Mr. Banks recorded the finding of several specimens of the southern house spider (Thalamia parictalis Htz.) at Washing- ton. —Mr. Banks noted the occurrence of the young of the chicken tick (Arc/as uiiniata} on diseased quail sent in from California by Professor Grinnell. From this he was inclined to think that this species is a native of this country and not introduced. OF WASHINGTON, VOLUME XI, 1909. 67 —Mr. Banks spoke of adopting the superfamily system for the spiders, which in his opinion showed the relationships to a better advantage, and gave an arrangement of the families in the proposed super families : Theraphosoidea (Theraphosidae, Atypidae). Scytodoidea (Scytodidae, Dysderidae, Oonopidx, Oeco- bidae). Drassoidea (Drassidae, Clubionidae, Zodariidae). Agalenoidea (Agalenidae, Dictynidae).

Lycosoidea (Lycosidae, Pisauridae, Oxyopidse). Attoidea (Attidae, Lyssomanidae). — Mr. Schwarz made some remarks on the twig-girdling long- icorn beetles of the tribe Onciderini. He said that hitherto the habits of only a few species were known and these all belonged to the genus Oncideres or to very closely allied genera. He now exhibited specimens of Ecthoca quadricornis Oliv.. from Trinidad, W. I., sent in by Mr. J. H. Hart, together with a cacao twig girdled by the adult beetle. This genus is remote from the genus Oncideres and may indicate that the whole tribe possesses the habit, in the adult stage, of girdling twigs. Mr. Schwarz added that, since the cacao and various species of rubber trees are being extensively cultivated in Central America, we may expect that quite a number of native insects will attack and injure these trees. He mentioned as an example that the Bureau of Entomology had recently received from Central America the larvae of two species of native Buprestidae, Euchroma goliath and Colobogaster cyanitarsis, with the state- ment that these insects were injurious to rubber trees.

That air is employed by insects in the process of ecdysis was first brought to my notice while watching a mosquito issue from the pupa. When the mosquito emerges from the pupa it is distended with air far beyond its natural size ; in fact it is inflated to such a degree that the integument is stretched to its utmost. This distension goes so far that the scales of the abdomen, which later overlap to form a complete covering, are separated so that the pale integument is visible between them, while between the segments there is a broad band of naked ?kin which later is folded under the ends of the segments. This inflated condition is gradually acquired during the pupal period. As the pupa grows older it becomes more buoyant, until finally, towards the period of eclosion, it can go down into me water only with great exertion, and when its efforts cease the pupa is immediately carried to the surface. A similar inflated condition appears to obtain in Coleoptera. T have noted that in newly emerged beetles the body is much distended. This ts particularly obvious in the thoracic region through the position of the elytra. At this time the elytra are separated from the hind margin of the pronotum by a consid- erable area of smooth integument which disappears beneath the pronotum as the body contracts to its normal dimensions. The great tension to which llie insect's covering is subjected at the time of ecdysis by the contained air was demonstrated to me in a striking manner by a chance experience. Last year, while at Cordoba, in Mexico, one of the attendants of the OF WASHINGTON, VOLUME XI, 19Q9. 69 hotel called my attention to "a very strange animal." Upon the veranda floor was a large cockroach (Periplaneta ainericana) , which had just moulted and was resting with its hind feet still upon the cast skin. Its glistening white color made the over- familiar insect appear strange to the attendant. 1 placed my foot upon the insect, whereupon it burst with a loud report which could be heard all over the building. It seemed evident to me that this inflated condition at the time of ecdysis, found in such widely different insects, could not be exceptional. More probably it is not only general among insects, but even an essential factor in the moulting process. Naturally I turned to entomological literature in the expectation of finding some explanation of this phenomenon. However, upon examining a number of the best treatises on entomology, I found, much to my surprise, that not one of them alluded to the function of air in ecdysis. Nevertheless it had been ob- served and studied and I finally came upon a series of papers which deal with this subject or touch upon it. The earliest of these papers is by Jousset de Bellesme and records observations upon the last moult of a dragon-fly.* He found that the dragon-fly upon emerging from the nymphal skin at once increased to about twice its previous size. This was accomplished by air pressure within, for, when the insect was punctured, it immediately collapsed. More careful inves- tigation showed that at this time the main tracheae were not filled with air, but the digestive tract was inflated with air. As there is a fixed quantity of blood within the body this blood is driven to the periphery by the pressure exerted by the greatly dilated digestive tube. Jousset de Bellesme also as- cribes the development of the imaginal colors and the hardening of the chitin to the abundant blood-supply thus forced to the periphery. In summing up he makes as his main point that the dragon-fly, by employing air to inflate its digestive tube, obtains the necessary force to accomplish the greater part of its transformation. Thus during ecdysis the digestive tract assumes a function entirely distinct from that of normal life. In concluding he remarks: "Everything leads one to believe that what I have described in the dragon-fly is repeated in a large number of insects and constitutes a very general mechan- ism in this class of animals." After a considerable interval Kunckel d' Herculais pub- lished his observations upon the ecdysis of certain Orthoptera *Phenomenes qui accompagnent la metamorphose chez la Libellule deprimee. Compt. rend. Acad. Sci. Paris, v. 85, pp. 448-450 (1877). 70 PROCEEDINGS ENTOMOLOGICAL SOCIETY and brought together all that was known regarding the role of air in the ecdysis of insects.* The studies of Kunckel d' Herculais were largely made upon an injurious locust of Algeria (Stauronotus uiaroccamts Thunberg) and similar conditions were found by him in other Orthoptera. In the acridiids observed by him the air is employed during each successive moult and furthermore by the female at the time of oviposition. Moreover the air plays an important part in the escape of the newly hatched young from the egg-cocoon. The young locust possesses, dorsally, between the head and the prothorax, a bladder (ampoule cervicale) which can be inflated or retracted. Six or seven of the newly-hatched locusts direct their efforts against the lid of the egg-cocoon and by means of their cervical bladders force it off. Such is the pres- sure thus exerted that the lid of the cocoon sometimes flies several centimeters. The cervical bladder is further employed when the young locust works its way through the crevices in the ground to the surface. By inflating and retracting this organ it is able to vary the dimensions of its body in such a manner that it can squeeze through crevices that would otherwise be impassable. When the young locust has reached the surface of the ground it casts its first skin and here the cervical bladder is again brought into service to rupture the skin. To inflate this cervical bladder blood is forced into it from the body cavity and this is accomplished by the agency of air. The air is taken into the digestive tract directly by swallowing until the crop becomes greatly inflated, and by this means the blood is pressed into certain parts of the body. Kunckel d'Herculais also found that at the time of moulting the tracheae are not filled with air and therefore the tracheal system takes no part in this process. As before stated this mechanism is again employed at each moult. In the last moult the wings are expanded by blood forced into them by the same means, that is, the inflation of the digestive tract with air. Lastly in the female the air performs an important function during oviposition, as by its means the abdomen is forced into the ground. This was discovered through the fact that a locust with an abdomen 5 cm. in length is able to bore a hole into the ground 8 cm. in depth. The air taken into the digestive tract greatly distends the abdomen and *Mecanisme physiologique de 1'eclosion des mues et de metamorphose chez les Insectes orthopteres de la famille des Acridides.

OF WASHINGTON, VOLUME XI, 1909 71 as the insect is firmly braced, by means of its fore and middle legs, the abdomen is forced into the ground.* Kunckel d' Herculais was fully aware of the wider bearing of these observations and in addition to these upon Orthoptera gives a number of less complete ones upon other insects. In earlier investigations he had found that the ptilinum of cyclo- rhaphous flies is not inflated by the pressure of air from the tracheae but by blood forced into it from the general body cavity by contraction of the thoracic and abdominal muscles. Most likely in this case also the digestive tube is distended with air when the imago issues from its puparium. Balbiani in- formed Kunckel d' Herculais that a similar function is indicated in the case of the homopter Conomelus limbata Fabr., for he had found that its digestive tube is filled with bubbles of air at the time of moulting. Hubbard in his observations on Psocus citricola Ashmead describes the office of air in the hatching of this insect. f The eggshell is perfectly transparent, so that the insect within can be readily observed. Before hatching the young insect swal- lows bubbles of air until the steadily expanding head finally bursts open the egg. This observation was repeated independ- ently upon an European psocid (Stenopsocus crnciatus L. ) and described more in detail by Peyerimhoff.J He found upon the amnion of the young psocid a frontal chitinous organ consisting of a dentate ridge. While this structure is the instru- ment for rupturing the egg-shell the ingested air furnishes the necessary force. After the insect has hatched the amnion is in its turn ruptured and shed by the pressure exerted through the air taken into the digestive tract. Busck has observed that the larva of the tineid moth Mar- mara salictella Clemens in its penultimate moult comes forth greatly inflated and afterwards shrinks to its normal size. He has recorded the curious use of the air in its digestive tract made by the larva of this moth when forming its cocoon. § Globules are expelled from the anus, which consist of an aggre- gation of small bubbles of air surrounded by some delicate substance. The larva thrusts its anus through openings in the *Mecanisme physiologique de la punk- chez les Insectes Orthopteres de la famille des Acridides. — Role de 1'air comme agent mecanique et fonctions multiple de 1'armure genitale.

The cases which have been cited, although few, are of such widely different insects that it seems almost certain that in this inflation of the digestive tvibe with air we have a principle which is fundamental in the moulting process of insects. If one stops to reflect it will appear quite obvious that something besides mere muscular exertion is necessary to liberate the insect from its exuviae. At the time of emergence the chitin is soft and therefore cannot offer sufficient resistance for any great muscular exertion. Thus at this time the insect is hardly capable of making full use of its muscles. Even if one allows for the lines of weakness, which are already determined in the pupal shell, it will still be admitted that it takes a considerable force to rupture, for example, the chrysalis of a moth. An insect issuing from its pupa hardly gives the impression of great muscular vigor. This subject well merits further inves- tigation. Thus in the case of Lepidoptera and Diptera the digestive tract is closed during the pupal period ; by what means does it become inflated with air? SUPPLEMENTARY NOTE. — At Dr. Howard's suggestion I have examined the work of Maillot and Lambert on the silk worm for further information on the process of ecdysis in the Lepidoptera.* The description given by them of the eclosion of Bomby.v niori is manifestly faulty and the interpretation of the processes involved is incorrect ; yet it shows that in this case also the swallowing of air is an important factor, if not in the escape of the imago from the chrysalis, at least in the expan- sion of its wings. The authors incorrectly state that the wings are expanded by the forcing of air into the veins. What is here important is the observation that while the wings are being expanded the crop is being rapidly filled with air. It is perhaps best to quote the original passage : En meme temps que les ailes s'etenclent et que les teguments devien- nent sees, le jabot, a 1'interieur du corps, vide du liquide qu'il contenait, se gonfle d'air rapidement ; aussi l'appelle-t-on sac a air. Les innom- brables trachees qui se ramifient dans 1'abdomen se replissent aussi d'une grande quantite d'air. The last statement, that the air taken into the crop serves to fill the tracheae, is of course an assumption and it is clear that we have here the process previously discussed. *Traite sur le ver a soie du murier ct sur le murier, p. 293 (1906). CF WASHINGTON, VOLUME XI, 1909, 73 Dr. Hopkins spoke of the various insects using air to aid them in different ways, citing the bladder used by 7^/ia/cssa to aid in oviposition and in Diptera of the breaking open of the puparium by the ptilinum. .Mr. Kincaid asked whether the air used in means of ecdysis had ever been analyzed to see if it was carbon dioxide or air. Mr. Knab replied that, in some cases at least, it was air ob- tained directly by ingestion immediately before ecdysis. -The next paper of the evening, "Some Habits of Kmpid Mies," by W. L. McAtee,* was discussed by Messrs. Schwarx, llarber, Knab, Hopkins, and Howard. -Professor Trevor Kincaid gave the society a very enter- taining talk on his experiences in Japan, telling of the mode of living, the various customs, the entomologists of the country, and work of obtaining and shipping the parasites of the gipsy moth.

[Neuroptera, Hemerobiidse.] BY NATHAN BANKS. The species described and recorded in the following pages were taken in Australia by Doctor R. C. L. Perkins, who collected in Queensland. Extremely few collectors have paid any attention to these insects, so it is not surprising that most of them are new. Only a few other forms have been recorded from Australia by McLachlan and by Gerstaecker. In general appearance they are very similar to our native species, but nearly all belong to new genera. Two genera, Sisyra and Micro in us, are represented in our country and in Europe. I have added the description of a new species from the Fiji Islands, also sent by Doctor Perkins. TABLE OF GENERA. 1.

Two previous records have been made of supposed Paussus larvae, but Doctor Boving shows that these must have belonged to other groups. The article, of which there is a summary in English, is accom- panied by a beautiful plate. —Mr. Schwarz referred to an article on the insect fauna of the Great Salt Lake, Utah, published in the Canadian Ento- mologist for 1891, pages 235—241, in which some space was devoted to the occurrence, in enormous numbers, on the shore of the lake, of the puparia of the salt-fly, Ephydra gracilis. These puparia accumulate on the sandy shores of the lake in a windrow many inches in width and several inches high. A photograph (Plate VI) illustrating a similar accumulation of Ephydra puparia on the shores of Mono Lake, in California, was taken by Mr. W. K. Fisher in September, 1901. The photograph is here reproduced, the black line along the shore showing the masses of the puparia. The particular species of Ephydra occurring at Mono Lake has been described as Ephy- dra hians Say. In response to a query Dr. Howard stated that the washing ashore was a perfectly normal habit of the puparia. Mr. McAtee spoke of the Indians drying the pupae, which were considered a great delicacy. Birds, especially the ducks and shore birds, are very fond of these pupae and swallows catch great numbers of the adults on the wing. -The following papers were accepted for publication : *A. G.

PLATE vi PUPARIA OF EPHYDRA HIANS SAY ON THE SHORE OF MONO LAKE, CALIFORNIA OF WASHINGTON, VOLUME XI, 1909 83 SOME SPECIES OF CALLIGRAPHA. [Coleoptera, Chyiomelidae.] BY FREDERICK KNAB. In those forms of Calligrapha in which the pale elytra show a pattern composed of sntural stripes, humeral lunules, and a number of irregular spots, the specific limits have been largely a matter of individual opinion. This must continue to be the case while collectors and systematists are content to dispose of such questions by a furtive examination of the speci- mens that chance puts in their way. The writer has long been dissatisfied with the accepted definition of the species and for some years has observed these beetles in nature whenever opportunity offered. It has become constantly clearer that distinct species are confused under the same specific name and that the definition of the species will have to be entirely refor- mulated. While the writer is not prepared to do this at present it seems advisable to characterize a few of these forms and it is hoped that this will stimulate others to give their attention to this group. Determination of the food-plants of the different species is the key to a proper understanding of them ; unfortu- nately our knowledge in this direction is still very incomplete. Furthermore, it is only with large series before him that the student can hope to gain a mastery of these difficult forms. The two species described here as rhoda and rowcna group with scalaris LeConte. There seems to be no doubt as to the form LeConte had before him when he described scalaris. It is the one which occurs upon the elm (Uliiins aincricana L.) and the linden (Tilia americana L.) and the form most frequently referred to under the name scalaris. In Calligrapha scalaris the pronotum and the elytral pattern are bright metallic green, sometimes with a strong bluish cast ; the form is rather elong- ate and depressed and the size averages larger than any of the other species. The surface appears shining; the punctuation of the pronotum is moderately coarse and close at the sides, fine and sparse upon the disc, though subject to considerable variation. The punctures limiting the elytral pattern are rather fine, the markings are flat, and show little if any convexity. The punctures upon the disc are very fine and well separated. The white ground-color of the elytra shows a silvery luster in sexually mature specimens. Calligrapha rhoda, new species. Form subovate, convex. Color of the body and elytral pattern dark olivaceous, submetallic; the legs, antennae, and palpi ferruginous yellow. 84 PROCEEDINGS ENTOMOLOGICAL SOCIETY Ground-color of the elytra creamy white ; in sexually mature specimens the greater part of the disc becomes suffused with dull red and those parts that remain pale take on a yellowish-silvery luster. The red color occupies the posterior two-thirds of the disc, beginning behind the humeral lunule ; a broad outer margin and narrow margins around the dark pattern are silvery. The elytral pattern consists of a double sutural stripe, to which are joined a heavy arcuate stripe along the middle third and a spot near the apex; the humeral lunule is double to beyond its middle and its inner branch extends obliquely close to the upper end of the arcuate mark ; the humeral lunule encloses two spots which are sometimes joined ; close to the outer margin near its middle is a small spot and there are a number of irregular small spots scattered over the disc. The epipleura are pale, with their outer and inner margins ferruginous. The punctures limiting the elytral pattern arc coarse and close and the markings are distinctly convex. The punctuation of the pale surface is coarser and closer than in C. scalaris. The head and pronotum are finely alutaceous and coarsely punctured ; the punctures of the pronotum are finer upon the disc, although nearly as dense as at the sides ; towards the sides there is a depression of con- fluent punctures. The labrum is ferruginous and there is a ferruginous spot upon each mandible. The claws are but slightly divergent. Length, 7 to 8 mm. Food plant: Corylus americana Walt.

This species feeds exclusively upon the hazel, both in the imago and the larval states, and as far as known it is the only species of Calligrapha found upon this plant. While the elytral OF WASHINGTON, VOLUMK XI, 1909 85 pattern is practically identical with that of C. scalaris, the pres- ent species has a facies which makes it at once recognizable. The form is shorter and much more convex than scalaris and the elytra, on account of the coarser punctuation, look much rougher. The pronotum and the elytral markings are a very dark olive, while in scalaris these parts are bright green or blue- green. The red color upon the elytra is only apparent upon sexually mature specimens and disappears after death. The claws are less widely divergent than in scalaris. The species occurs but sparingly upon its food-plant. Calligrapha rowena, new species. Form subovate, convex. Color of the body and elytral pattern dark blue-green, submetallic ; the legs, antennae, and palpi ferruginous yellow ; labrum ferruginous. Ground-color of the elytra yellow ; in sexually mature specimens the greater part of the disc is bright orange-red, the anterior third and a broad outer margin golden. The elytral pat- tern consists of a double sutural stripe to which is joined, behind the anterior third, a short and heavy arcuate stripe ; before the posterior third is a detached arcuate spot which represents the posterior branch of the complete arcuate stripe of C. rhoda and C. scalaris; the spots near the apex, which in rhoda are usually large and joined to the sutural stripe, are either obsolete or small and detached. The humeral lunule is short and very heavy, double to beyond the middle; it en- closes a heavy, roughly lunate or rounded spot which is sometimes fused with it. There is a large spot on the outer margin near its middle ; the spots upon the disc are small and vary in number from 3 to 8 upon each elytron, while in rhoda there are 10 or 11. The punctures limiting the elytral pattern are coarse and the markings are more or less convex. The punctuation of the disc is distinctly coarser than in rhoda and consequently the surface is uneven. The epipleura are pale with their outer margins ferruginous. The head and pronotum are aluta- ceous, but more shining than in rhoda and coarsely punctured. The punctures of the pronotum are rather sparse and those upon the disc but little finer than the ones at the sides; half-way down the sides is a depression with more or less confluent punctures and bounded by a more or less impunctate area. The claws are more divergent than in rhoda. Length, 6.5 to 8.5 mm. Food-plant unknown. Localities: Montreal, Province of Quebec (6 June, 1899, 10 June, 1906, 23 June, 1907, G.

This species is of striking appearance on account of the reduction, both in number and size, of the discal spots of the elytra and in fresh specimens this is enhanced by the brilliant red discal color. It is even more robust in form than rhoda. Calligrapha amelia, new species. Closely related to Calligrapha philadclphica Linmeus. Form elong- ate-ovate, convex. Color of the body and elytral pattern dark blue- green, submetallic ; the legs, antennse and palpi ferruginous yellow ; labrum, and the mandibles in part, ferruginous. Ground-color of the elytra white with slight creamy tinge and, in sexually mature specimens, with silvery luster. The elytral pattern is similar to C. philadclphica. The sutural stripe is very narrow, usually green but shading to fer- ruginous in some specimens. The subsutural stripe is broader, de- tached, and does not attain the apex ; in some specimens it is abbre- viated or interrupted posteriorly. Outside of the subsutural stripe, medianly, is a long arcuate stripe which is usually more or less broken in the middle. The humeral lunule is usually broken into four spots, of which the posterior oblique one is the largest ; the spot enclosed by the lunule is rather large, rounded or roughly lunate. The spots upon the disc are heavy, more or less rounded, and about 12 to 15 in number upon each elytron. The punctures limiting the pattern arc moderately coarse, the markings slightly convex ; the punctuation of the disc is rather coarse and sparse. The epipleura are pale with ferruginous outer margin. The head and pronotum are obsoletely alutaceous, coarsely but not densely punctured ; the punctures on the sides of the pronotum tend to form pits and those upon the disc are but little finer. Length, 6.5 to 9 mm. Food-plant: Alnus ruqosa (Du Roi ) K. Koch (serrulata Willd.). Localities : Washington, D. C.

National Museum and of the author. This species averages larger than C. philadelphica; it is a little more robust and the markings are heavier. The head and pronotum are shining blue-green, while in philadelphica they are distinctly alutaceous and the color is a duller brassy green. In philadelphica the inner lunule of the humerus is nearly always complete, gently arcuate and more slender; it encloses two widely separated slender spots and all the markings are more delicate. C. amelia, in the imago and larva states, occurs exclusively upon the alder (Aim-is rugosa) ; C. philadelphica lives only upon Cornus (Cornus stolonifera Michx., Massachusetts, G. Dim- mock; C. amomum Mill., vicinity of Washington, D. C., Knab). In the vicinity of Washington these two species may often be found in close proximity upon their respective food-plants, a natural result of the habits of these two plants. The writer is well aware of the extensive literature which deals with the species of the group to which the foregoing belong. However, until our knowledge is more complete, any attempt to handle this literature critically would only add to the existing confusion. Certain it is that the numerous mis- identifications, not only of the beetles but of the food-plants as well, have made the subject a most complicated one.

Gelechia placidella Zeller, from Vancouver Island, has hither- to been overlooked and is mentioned neither in my Gelechiid revision nor in Dyar's List of North American Lepidoptera. The type in Lord Walsingham's collection, which I have now examined, proves the above synonomy. Sophronia roseicrinella, new species. Second joint of labial palpi rosy white, exteriorly mottled trans- versely with fuscous; the well-developed brush dusky; terminal joint 88 PROCEEDINGS ENTOMOLOGICAL SOCIETY white, strongly mottled with black and with black tip. Face white. Head and thorax mottled with fuscous. Fore wings with the rosy- white ground color strongly overlaid with brown and fuscous scales, especially on dorsal half and towards apex. On the middle of costa begins an outwardly strongly oblique, ill-defined, brown shade ; at apical third is a narrow, strongly outwardly angulated, spear-formed fascia of unmottled rosy white, edged towards the base of the wing with dark scales ; the apical third of the wing outside the fascia is neatly mottled with black on white ground and just before the sharp- pointed apex is a small black round dot.

Anacampsis crescentifasciella Chambers. Dyar, List North American Lepidoptera, No. 5703, 1903. This species, which in collections has hitherto been repre- sented by the unique type in the U. S. National Museum and some of Chambers's original specimens in the Cambridge Mu- seum, was lately received from Mr. W. D. Pierce, who bred four specimens from Krameria seeundiflora at Dallas and Victoria, Texas. Gelechia lipatiella, new species. Labial palpi, tongue, face, and head ochreous white. Antenna: blackish brown with narrow white annulations. Thorax blackish brown. Fore wings blackish brown with white markings ; basal and dorsal parts lighter brown with a strong coppery sheen ; at basal fourth is an outwardly oblique, white costal streak, which reaches beyond the fold, but not to the dorsal edge ; at apical third of costa is an inwardly oblique white fascia of the same angle as, but in opposite direction from the first costal streak. Between these two white streaks is a nearly round, but not sharply defined, white spot just within the costal margin; on the extreme apex before the cilia are a few white scales.

Schwarz from the flowers of pawpaw (Asiminia triloba). The larvae are short, thickset, purplish or greenish white, with light-brown head and brown divided cervical shield. The adults issued May 16. This is an unusual food plant for the genus Hemimene (Dichrorampha), which has been supposed to be confined to the Compos itse. CAMERARIA Chapman. The Entomologist, xxxv, p. 141, 1902. Type — Lithocolletis guttifinitella Clemens. Miss Annette Braun's "Revision of the American species of Lithocolletis"* is a very valuable addition to the literature on American microlepidoptera, and the author deserves great credit for her careful work, and especially for the excellent plates, which are a great help in the identification of the many closely allied species of this group. The generic arrangement, however, shows some lack of logic and cannot be maintained. The genus Lithocolletis, as understood in Dyar's List of North American Lepidoptera and by the earlier American workers on the group, consists, as repeatedly pointed out by Clemens and Chambers, of two main divisions — the cylindrical- larva group and the flat-larva group. These two branches have developed parallel from gracilariid stock, probably not from the same but from nearly allied origin. There can clearly not have been any crossings between these two branches of devel- opment since the first separation ; neither could one have been developed from the other. That the imaginal characters are structurally identical could be expected; they started alike and have had the same condi- tions to meet; but each group has retained its typical larval development, its typical feeding habits, its peculiar cocoons, and its typical coloration. In any of the stages it can at a glance be decided to which of the two groups a given species belongs. In the one of these main branches of the phylogenic tree a Trans. Am. Ent. Soc., xxxiv, p. 269-357, pis. xx-xxiv, 1908. 100 PROCEEDINGS ENTOMOLOGICAL SOCIETY few species have not reached as far as the majority in the development towards the Lithocolletis ideal ; they have retained a small unessential vein from the ancestral type, which the main body of species have lost ; and a single species is slightly in advance over the main body by having lost an extra vein. Thus we have : LITHOCOLLETIS (Authors). Porphyrosela Braun | Phyllonorycter Hiibner Cameraria Chapman Cremastobombycia Braun Cylindrical larva Flat larva Allied Gracilariid stock It may be that these subdivisions of the cylindrical-larva group are worthy of subgeneric rank ; I consider the differences too trivial for generic use. It would be logical to include all the species of both groups in one genus ; this at least would be a natural group ; but to erect subgenera for two of the subdi- visions of the one main branch and then include the other main branch in the third subdivision is obviously unscientific. The best way is to recognize the two easily defined main divisions of the group as good genera, for which the names Phyllonorycter Hiibner* (type, rajclla Linne) and Cameraria Chapmanf (type, gutti finite Ha Clemens) must be used. I have treated this comparatively unimportant case in some detail, because it elucidates similar cases of much more far- reaching consequences, in which I think the present classifica- tion of the microlepidoptera weak, or rather, unnatural. We have been doing our classification too 'much horizontally, so to say — any twig on the entire phylogenic tree which has reached a certain type of imaginal structure has been placed in such or such a genus or family without sufficient regard for its origin. This does not produce a natural system. In the above diagramatic phylogenic tree it is of course the easiest to say that everything which has reached a certain level A is to be considered a systematic entity and that what *Hiibner, Tentamen, 1806. fThe Entomologist, xxxv, p. 141, 1902. WASHINGTON, YOU'MK XI, 1(11 reaches to the level /»' i- another family or -ubfamily, as the characters may warrant, irrespective of whether it originated from main branch /, //, or III . JHit sucli a system would be purely mechanical and not ac- cording to nature's own divisions. And while we with (Un- limited powers of observation are forced to adopt to some extent some mechanical arrangement in order to get any classi- fication at all, it is manifestly obligatory, when we can trace the phylogeny and realize the true natural lines, that we utilize such knowledge and not continue our temporary mechanical system, merely because it is easier.

The larva makes a small, very pale straw-colored upper mine in leaves of oak around Washington. The mine is nor- mally placed at the edge of the leaf and frequently causes the edge to bend over in a small fold. The species has several generations in this vicinity ; the first mines collected in early April, 1900, produced moth the same month and others were bred in July and August.

The unique female specimen on which Lord Walsingham founded his genus Pseudoxylesthia had lost its head and had through a mistake of the preparator been supplied with a head of quite a different insect, as we discovered on closer examination at Merton Hall last summer.

The 231st meeting of the Society was entertained by Dr. Gill at the Saengerbund Hall, 314 C Street X.W., on the even- ing of May 13, 1909, with the President in the chair and the following present : Messrs.

[Hymenoptera, Tenthridinidse.] BY E. A. SCHWARZ. During the latter part of August, 1906, it was noticed that the willows on the Potomac River about 10 miles above Wash- ington were utterly defoliated by some insect, apparently not a single tree escaping the injury. No observations on the insects were made during that year, but in the following year we found that a certain percentage of the defoliated willows, roots and all, were killed, while many other trees were killed above ground in that year and the defoliation was again a complete one. We were prevented from visiting the locality until the latter part of August, when it was ascertained that the author of the mischief had been the larva of a saw-fly. At that date the insect had disappeared, and on September 2 a party of Washington entomologists made a determined effort to find its cocoons. None were found under the defoliated trees, but a few were obtained in the more elevated ground. These were kept in breeding cages over winter, but, as is usually the case in trying to breed saw-fly cocoons, they never hatched. In the month of April, 1908, there occurred two freshets in the Potomac River of considerable magnitude, and early in the month of May a place was found, Plummer's Island, where many thousands of the cocoons (pi. ix, fig. 9) had been washed up by the high water. Cocoons from this place were taken back to Washington and from them quite a number of the imago saw-flies were obtained in our rooms during the last week of May. On May 29 the first specimens were seen to emerge at the place on Plummer's Island just mentioned, the saw-flies apparently copulating immediately after issuing on the low plants that grow on that place. On May 30 the first eggs were observed by us, and the female saw-flies were watched in the act of oviposition. The issuing of the saw-flies from their cocoons and the oviposition extended from that date to the first week in July. In ovipositing the female saw-fly at first carefully explores the surface of the willow leaf, then commencing at the tip of the leaf and proceeding toward the base (pi. vm, fig. 1 ), inserts its eggs at regular intervals in the edge of the leaf. It takes about one minute for the saw-fly to oviposit one egg. When one side of the leaf has been furnished with eggs, the saw-fly re- turns to the tip of the leaf and lays eggs on the other side of the leaf. The number of eggs (pi. vm, figs. 2-3 ) laid in one leaf OF WASHINGTON, VOLUME XI, 19Q9 107 varies considerably. \Ye counted more than 60 in one leaf. They are at first not easily visible unless the leaf is held against the light, but gradually the color of the leaf tissue which surrounds the eggs becomes more or less brownish, when the eggs can be seen without difficulty. A fortnight later the first larvae were seen. No observations were made on the number of molts or of the development of the larvae, because, as stated above, the oviposition extended more than two months and there were always small and large larvae to be found on the same branch of the willows. In the beginning of August the full-grown larvae (pi. vm, fig. 5) were seen to drop to the ground and to crawl off in search of a place for pupation, which was never on the low ground where the willow trees grow, but on the slope of the higher ground well above the height of a moderate freshet. However, in this year comparatively few of the larvae reached full maturity. There were many of them starved to death in places where a complete defoliation had taken place. Countless others were killed by what we consider as a fungoid insect disease, so that their dead bodies lying on the ground or hanging on the trees made a very unpleasant stench. Some observations were made on two species of parasites. From numerous leaves beset with eggs which were collected in the first week of June we obtained in our breeding jars a large number of an egg parasite which seens to be undescribed, and cannot at present be referred to by name. According to Mr. Crawford it belongs to the Tetrastichidae. We never observed in the field the issuing of these parasites from the eggs, nor did' we ever see in the field a single specimen, but from the fact that \\ e bred the same egg parasite from eggs collected in the latter part of June and the early part of July, it must be concluded that the parasite is able to undergo two generations in the eggs of a single generation of the host. A second parasite, which has been named by Mr. Crawford as Testrastichus hylotomce, was first observed by us issuing in great numbers from the cocoons found in the ground. The imago parasite was seen frequently by us in July, flying singly around behind the saw-fly larvae. The latter manifestly were1 aware of the proximity of an enemy, and were moving their abdomens in the air in the fashion of many other saw-flies, try- ing to frighten off the parasite. In this case it is evident that this particular species of parasites hibernates in the body of the -uw-flies and issues only the next spring. Of other enemies only a single species of a Pentatomid was observed to suck the half-grown saw-fly larvae. The saw-fly under consideration (pi. VITI. fig. 4) agrees per- fectly well with specimens named in the U. S. National Museum 108 PROCEEDINGS ENTOMOLOGICAL SOCIETY collection as Hylotoma pectoralis Leach, and its larvae (pi. vm, fig. 5) also agree with specimens preserved in the National collection. There may be, however, some doubt as to the cor- rect determination, since the only records we have on the food habits of the saw-flies are not in accord with those recorded here. Rev. Thomas W. Fyles, in the Canadian Entomologist (1886, vol. 18, p. 38), has noticed these larvae in great numbers feeding on the white birch in the vicinity of Quebec during the month of September, Mr. John George Jack (Psyche, vol. 6, 1891, p. 10) bred the saw-fly from larvae found the previous summer feeding on the foliage of Bctula alba in the Arnold Arboretum at Jamaica Plain, Mass, and Dr. Dyar (Can. Ent., vol. 27, p. 210, 1895) found them on Betula lenta at Wood's Hole, Mass., and on Betula papyrifera at Keene Valley, N. Y. Near Washington, D. C., is a species feeding exclusively on the black willow (Salix nigra}, leaving intact every other species of willow and never being found on the only species of birch (Betula nigra) that occurs on the banks of the Potomac. The full extent of the injury is not known to us. Mr. H. S. Bar- ber traced the injury along the banks of the river from near Washington up to Seneca, a distance of about 22 miles. All the willows growing on the more elevated ground were left intact. The accompanying series of photographs were made by H. S. Barber. EXPLANATION OF PLATES. PLATE VII.

OF WASHINGTON, VOLUME XI, 1909. 109 Dr. Dyar stated that while the larvae of the species of Hylo- taina were distinct, the adults were hard to distinguish, and re- ferred to an article by himself (Journ. N. Y. Ent. Soc., v. IS, 1X07), in which five different types of Hylotouia larvae pro- duced a jumble of different adults. Further study of tin- species is badly needed. Dr. Hopkins thought that this species might become a serious pi-st, especially if it should work on other species of willow, such as the basket willow. * — Mr. Hooker presented the following paper: NOTE ON AN EXTRA NYMPHAL MOLT OF ARGAS MINIATUS. [Acarina, Argasidae.] BY W. A. HOOKER. As an introduction to the observation which I wish to record, a brief account should be given of the molting habits of the ticks. As is generally known by entomologists, in order to develop it is necessary for ticks to engorge blood. Immature ticks molt following each meal of blood. Ornithodoros sai'ig- nyi and O. moubata, two African species, the latter of which transmits human tick fever, are exceptions, however, as both are inactive in the larval stage and pass the first molt before ingesting blood. While there is no evidence that ticks develop through feeding upon plant juices, as do some of their near relatives, the possibility of which has even recently been con- sidered by one investigator, .it is undoubtedly true that they (at least the Ixodid ticks) imbibe more or less moisture. With the exception of Ornithodoros mcunini, it appears to be neces- sary in order to oviposit that blood be engorged following the last nymphal molt. While the Txodid ticks pass but two molts (larval and nym- phal) during their life, there appears to be a difference in the number passed by the Argasids. In the genus Ornithodoros, while nicgniiii passes but two molts before arriving at the adult stage and none afterwards, sark/nyi and moubata appear to have three or more, and the latter is reported to continue molt- ing as an adult. Whether there is a variation in the number of nymphal molts in each of these two latter species, however, does not appear to have been determined. The species of the 110 PROCEEDINGS ENTOMOLOGICAL SOCIETY genus Argas have generally been supposed to pass three ecdyses before arriving at the sexually mature stage. This has been reported by Lounsbury to be the case with Argas persicus, the South African fowl tick, the habits of which appear to be identical with those of our fowl tick, Argas ininiatus. The structure of these two species is so much alike that Nuttall and Warburton, in their recent monograph of the Argasidse, have considered ininiatns a synonym of persicus. In breeding experi- ments u'itli ininiatus I have found that something like one- fourth of the individuals bred to maturity, under similar con- ditions, hare an e.rtra or tliird nymphal ecdysis, making a total of four ecdyses during their life. This is not a sexual varia- tion, as both males and females were among those which molted a fourth time before the external sexual characters appeared. Neither is it due to a difference in the food supply, as all of the ticks were well engorged, nor to climatic conditions, since it occurred under exactly the same conditions as were furnished the other ticks. It has occurred in broods bred during the fall and winter and during summer. The engorgement of blood, in each instar, before the following ecdysis can take place, necessitates an exposure to the danger of discovery by the fowl, mouse, or other enemy, or to injury in other ways. It thus appears that the three-molt habit is most advantageous, since but four instead of five engorgements are necessary before reproduction can commence. A much greater advantage is gained than is at first apparent, since it is in the more mature stages that the exposure to danger in the search for the host is greatest. These three-molt ticks may perhaps be considered as descendants from a mutant which, through the process of natural selection, have now come to predominate. On page 121 of Volume TIT of the Proceedings of this Society, Dr. C. V. Riley states that he knew a specimen of Argas rejlcxus to re- main alive in a corked vial without food for some five years, molting repeatedly during the period. The statement, however, both as to the period of longevity and number of molts, still remains to be substantiated. It is well known that in some insects the number of molts may vary, an excessive number at times being clue to some physical cause, such as a lack of food combined with low tem- perature or to a partial starvation. This has been considered by Packard as due to the hypodermal cells retaining their activity. Packard has reviewed the literature on the number of molts in insects in his Textbook of Entomology, pages 615- 618, but cites no case in which a variation occurs when similar amounts of food and climatic conditions are supplied. OF WASHINGTON, VOLUME XI, 1909 m Dr. Dyar said that in Lepidoptera there was quite a variation in the number of molts, and that if food was scarce the larva- had more molts. He was of the opinion that cases occurred in the Lepidoptera similar to the one cited by Mr. Hooker, in which the number of molts occasionally varied under appar- ently similar conditions. Such an occurrence, however, i- rather unusual. Air. Schwarz called attention to the fact that in one of the past volumes of Proceedings of this Society, note was made of a dermestid which lived on for years and continued to molt when deprived of food. Mr. Caudell presented the following paper: MISCELLANEOUS NOTES ON ORTHOPTERA. Bv A. N. CAUDELL. A genus with more than one originally included species, none of which have been designated as type, can be referred in part here and in part there, but when a type species is once designated the genus is given entity and must thereafter follow its type. Kirby refers Phasina crawanycnsc Haan to his genus Phasgania. But crawangcnse is the selected type of Dixippus Stal and thus Phasgania must be placed in synonymy under that genus, which has priority. Dixippus is therefore resur- rected from the synonymy under Lonchodcs Gray, and under it is to be listed the species recorded in Kirby's catalogue under Phasgania. Phasina graveolens King* is eligible to citation in catalogues in synonymy under Anisomorpha hnprcstoidcs Stoll. Some time ago I showed the generic name Phyllodromia Serv. to be preoccupied by the earlier dipterous genus of the same spelling, and replaced Serville's name by the new generic name Blattclla. This action has been almost generally accepted, but two noted English writers have not done so. As the reason for this one of the writers. Mr. Kirby of the British Museum. wrote me that he was not sure but that Liosilpha Stal was available for use in this connection and. until time permitted *Proc. Ent. Soc. Lond., 1867, p. LXXX (1867). 112 PROCEEDINGS ENTOMOLOGICAL SOCIETY the settling of the point, he had thought best to use the Ser- villean genus with both Liosilpha and Blattella cited in synon- ymy. The other writer not accepting the change, Mr. Shelford, of the Oxford Museum, who is a specialist on the Blattidae, writes as follows : "I note that you use Blattella for Phyllo- dromia Auct. What is wrong with Liosilpha Stal ? Personally I stick to Phyllodromia and will do so until dipterists make use of it, which they don't do at present." Recently* Mr. Shelford examined pumicata, the type of Liosilpha, and found it not to be congeneric with germanica, the type of Phyllodromia. He thus proves Liosilpha unavailable for use in the place of Phyllodromia, but he still uses Serville's name, ignoring Blat- o o tella. This stand, which is in accordance with the nomen- clatorial views expressed in the above extract, seems indefen- sible, and it is to be deplored that so able an entomologist should so arbitrarily set aside priority, the cornerstone of sys- tematic science. Phyllodromia Zetterstedt, the dipterous genus of 1837, preoccupies Phyllodromia Serville, the orthopterous genus of 1839, no matter if the earlier name is in present use or not. Therefore, the replacing genus Blattella should be used in conformity with the laws of nomenclature. Ceratinoptera castanca Shelford (Sjostedt's Exp. Kil. Meru, etc., 17, Orth., 2 Blatt.. 22, 23, 1907), is preoccupied by Ceratinoptera castanea Brunner (Syst. Blatt., p. 77, 1865). In view of Mr. Shelford's knowledge of the Blattidse it seems inconceivable that this preoccupation is unknown to him. It is probably intentional on his part and in full accord with his avowed disregard of the law of priority. Deeming a new name for the preoccupied Ceratinoptera castanea Shelford a sys- tematic necessity, I propose the name shelf ordi for it. Nauphceta basalis Kirby has been referred to the genus Paranauphceta and is preoccupied in that genus by P. basalis Serville. Kirby's species will require a new name if it is con- generic with Serville's species. The new generic name Polychitonacris was proposed by Mr. Rehnf to replace the preoccupied genus Polysarcus of Saussure. Pycnosarcus was proposed for the same purpose three years earlier by Bolivar. Thus Polychitonacris Rehn falls as a syn- onym of Pycnosarcus Bolivar. Hadrotetti.v uiundus Scudder is a Trimerotropis, as deter- mined by an examination of the types, and belongs in the * Deutsche Ent. Zeitschr., p. 120 (1908V fProc. U. S. Nat. Mus., vol. xxxvi, p. 162 (1909). OF WASHINGTON, VOLUME XI, 1909^ pacifica group. Derotmema lentiginosum Scudder is also a Trimerotropis and is synonymous with T. gracilis Thomas. Phyllonotus Hancock:|: was based upon three species, plagia- tmn, sagrai, and saussitrci, all of which were soon afterwards shown to really belong to the genus Choriphyllum of Serville. This was all through an error of compilation, as later explained by the describer, but the genus Phyllonotus as published falls as a synonym of Choriphyllum and a new name is required for the species intended to be placed under Phyllonotus. These species are Cicada rhoinbea Linnaeus, Choriphyllum foliatiim Hancock, and Choriphyllum u'cstwoodi Hancock, and for them I propose the generic name Zaphyllonotum, of which foliatuni may be considered the type. Phyllotetti.v Hancockf can not be used for the above, as it sinks into synonymy under Choriphyl- lum along with Phyllonotus, the genus for whose replacement it was made. Orphulella walkeri Bruner (Ohio Nat., vol. vn, p. 11, 1906), is preoccupied by Orphulella walkeri of the same author de- scribed two years earlier (Biol. Cent.-Amer., Orth., vol. n, p. 73). The previous name was suggested to replace the Steno- bothrns me.ricanus of Walker (which Bruner refers to Or- phulella) in case that species is not proved a synonym of punctata DeGeer. This is a reprehensible method of estab- lishing new names, but, being published, the name has place in ii'smenclatorial literature and can not be ignored. The later species is from the same general region as the earlier one and is said by the describer, in discussion, to be a possible synonym of one of Walker's illy defined species of Stenobothrus. The walkeri of 1904 was made to replace Walker's mexicana in case it was found to be distinct and the zvalkeri of 1906 was definitely described as a new species and merely suggested as a possible synonym of one of Walker's species of Stenobothrus. Thus these two species walkeri can not be considered as the same conception and the later one, that of 1906, must fall. To replace it I propose the new specific name losamatensis. Snodgrass (Proc. Wash. Acad. Sci., vol. iv, p. 439, 1902), describes Sphingonothns trincsotis and says it occurs in three varieties and describes these as chathamensis, indefatigabil en- sis, and albemarlensis. As, by the laws of nomenclature, one of the varieties of a species must bear the species name, I designate the typical form as chathamensis, which name there- *Tett. N. Amer., p. 45 (1902). tEnt. News, vol. xiii, p. 188 (1902). 114 PROCEEDINGS ENTOMOLOGICAL SOCIETY fore is to be quoted in synonymy under trinesotis. The same conditions prevail in Sphingonothns tetranesiotis on page 444 of the same article. Here four varieties, charlesensis, bar- ringtonensis, hoodensis, and indefatigabilcnsis, are described, none being given the specific name. I here designate the last described variety, indefatigabilensis, as the typical form, thus sinking it into the synonymy under tetranesiotis. From a copy of Bolivar's article in Bol. Soc. Espan. Hist. Nat., vol. v, pp. 343—347 (1905) I find, from pen corrections entered by the author, that the Rhacoclcis gessardi there men- tioned, and noted by me in Genera Insectorum, Fasc. 72, p. 5 ( 1908), is an error for maura Bonn. Gryllacris incerta Tepper (Trans. Royal Soc. S. Austral., vol. XV, p. 154, 1892) is invalidated by the previously established Gryllacris incerta of Walker (Cat. Derm. Salt. Brit. Mus., vol. i, p. 189, 1869). The first described one is now referred to another genus ; but once a homonym always a homonym, so the last named species must be renamed. In place of Tepper's name I therefore propose certa. Prochilus Brulle of 1835 is preoccupied by the mammalian genus of the same spelling by Illiger in his Prodr. Mammal, et Avium, p. 109 (1811). The name was also used prior to 1835 by Cuvier in ichthyology. To replace the preoccupied ortliop- terous genus I propose the name Zaprochilns. Sia Giebel ( Zeit. fur Gesammt. Naturwiss., vol. vin, p. 114) was probably published in October of 1861. This genus seems to be the same as Licola Walker (=Bugajus Brunner) and, being the earliest, is to be used. The type species, 5". fero.r, replaces Saussure's species couloni, as that species was not described until January 22, 1862 (Ann. Soc. Ent. France (4), vol. i, ]). 490, pi. xii ). -Mr. Schwarz noted that the name of the species of the insect catching grass referred to in Volume VIII. page 5, of the Proceedings, should be Cenchnts I'iridis. -Mr. Schwarz said that the species of Hymenoptera which was referred to in Volume X, page 62, of the Proceedings, was not the blue mud-dauber, but Trypo.vylon albitarsc Fabr. -The following papers were accepted for publication : OF WASHINGTON, VOLUME XI, 1909, H5 NOTES ON THE FAMILY >EGERIIDyE (SESIID/E), WITH A SYNOPTIC TABLE OF THE NORTH AMERICAN GENERA. | Lcpidoptera, .'Hj>xriid;c. \ BY AUGUST BUSCK. The character which has been relied upon* to distinguish the family ^-Egeriidae, namely, the absence of vein 8 in the hind wings, proves to be an illusion. The apparent ease with which the venation can be studied in the more or less transparent wings of this group of moths has probably occasioned the error, but if careful slides are made of softened and denuded wings, it is plainly seen that the normal eight veins are really present in all the genera, though veins 7 and 8 are sometimes partly coalescent. The mode of attachment between the fore wing and the hind wings in this family is peculiar and has added to the difficulty of interpreting the venation rightly. Aside from the frenulum, which normally, though not invariably, f is single in both sexes, the hind wing has a narrow, sharp, upward fold along the costa, into which the downwards-folded dorsal edge of the fore wing fits snugly and securely. Anyone who has spread moths of this group must have noticed how easy the task is, if the speci- men is fresh and soft. By merely guiding the fore wing up into position the hind wing follows along; but if once the two wings arc separated, it is exceedingly difficult to get them into their natural relations again and a poor mount results. This is be- cause the fold on the hind wing is elastic and is difficult to wedge open again if the edge of the fore wing has slipped out. This fold locks the long, thin wings together very effectually and enables the strong flight of these moths. If a pair of wings of a dry, well-mounted specimen is placed on a slide il is practically impossible to separate them without injury to the wings, except by sliding them longitudinally away from each other. When this fold on the hind wing is softened and straightened out in a slide-mount the costal and subcostal veins are both observable. A similar, though not quite so strongly developed, arrange- ment for holding the wings together is found in the Syntomidae. There is considerable difference of opinion about the nomen- clature of the family /Egermke (Sesiidse). The writer is in- *Mi-yrick. Handbook Brit.

He has, however, at the present time no opportunity to reach conclusive opinions on these questions, which are essentially foreign to the science of entomology proper- — and the purpose of the present paper is solely to deal with the structural questions. For con- venience, therefore, the names of the genera have been adopted as they are given by Beutenmuller* and as used in the present American List.f The type of each conception is cited at the end of the article and any other set of names can thus readily be substituted. To further assist in this I have appended the principal synon- ymy as used in (1) Meyrick's Handbook of British Lepidop- tera, (2) Rebel, Cat. Lep. Europ., and (3) by Lord Walsing- ham and Mr. Durrant, the latter of whom has kindly sent me their opinions on the subject in full. As to the systematic position of the family I concur with Meyrick in regarding it a derivative from the Hyponomeutid?e and coordinate with the other true microlepidopterous families, such as the Gelechiidse, Oecophoridae, etc. The writer has had some difficulty in using the synoptic table of the genera in Beutenmuller's valuable Monograph,! and ventures to publish the following, which may perhaps also enable a more natural sequence of the genera. The difficulty in using the synoptic table in the Monograph is augmented by the text figures of the venation, to which one naturally refers for confirmation ; these figures are almost with- out exception faulty and in some cases very misleading. To cite some examples: Fig. 8 of Melittia satyrinifonnis lacks a vein (3) in the hind wing; figs 9 and 10 of Gaea emphytifonnis and of Enhagcna ncbraska: show veins 3and4 in the hind wings connate instead of approximate; fig. 11 of Alcathoe caudata shows one vein (10) too many in the fore wing and shares the main fault of nearly all the other figures in showing vein 7 in the fore wing ending far down on the dorsal edge instead of at or above apex. All of the genera except Melittia and Aegcria (in the sense of Beutenmuller's monograph) have vein 7 in the fore wing to or above apex. *Monograph of the Sesiids" of America, Mem. Amer. Mus. Nat.

So much attention has been directed of late by collectors to this group, that it has resulted in the capture of many new and singular forms. These have accumulated with great rapidity during the past vear, and it seems advisable to give names to some of those which in my opinion require to be thus accorded specific distinction. Many more remain yet to be described, especially among the Eupithccicc. It was with the intention of reducing somewhat the unwieldy mass of material at present classed as such that I proposed the genus Nasusina. I find in practice that it works out with clearness the species which should be placed under it, and that they present when grouped three well-marked styles of ornamentation. One is represented by the angulate linear picturing of the type, inferior Hulst, and another by niveifascia Hulst and allies, with large blotches of color, and a third by dcspcrata Hulst, with heavy, oblique cen- tral wing-bands. With them must be included, Eup. leucata Hulst, the unique type of which is at New Brunswick and was recently examined by me. To the first group will belong the species described below. Genus NASUSINA Pears. Nasusina opinata, new species. Expanse : Male, 13 mm. ; female, 16 mm. Palpi moderate, heavy, black : above and at tip, white. Antennae slender, shortly ciliate in male. Front whitish crossed below antennae and above clypeus, with a narrow black line. Vertex, thorax, and abdomen with gray and white scales mixed, the latter with pale ring at base. Second segment and tufts which are well marked, jet black. All wings much produced at apices, which are rounded. Color pale silver-gray, with narrow cross lines of black, much like inferior Hulst in pattern. A series of these lines parallel to each other from the basal area of primaries, the outermost one-third from base rounding out sharply and almost touching; the small oval jet-black discal dot turns sharply backward and reaches inner margin about one-half its costal distance from base. A narrow clear space follows, including discal dot. Then a series of four black parallel hair-lines, the outermost much the heaviest and forming inner boundary of extra discal geminate pale lines. These lines run nearly straight across costa, then sharply toward outer margin, making at vein 6 a backward turn, with angle blunt at apex, and run in waves to inner margin, parallel with outer margin. Extra 120 PROCEEDINGS ENTOMOLOGICAL SOCIETY discal parallel to these lines and not paler than central space, which is somewhat clear from markings. Subterminally darker, having between veins 4 and 6 a faint patch of black scales and also subcostally at apex a few pale brownish- scales are apparent within the terminal narrow black line cut at veins. Subterminal white line much broken ; clearer at anal angle. Fringes pale, dark at base. Secondaries with lines as on primaries, the geminate pale line running parallel with and near to outer margin, the rest straight across wing from inner margin to costa, where they become indistinct. A central clear space as in primaries, but with its outer boundary line traversing the discal dot, which is a mere point. A black triangular patch at basal inner margin. Beneath, pale silvery-gray, the lines above clearly reproduced, those bordering the geminate extra discals darkest. Discal dots jet black, distinct on all wings. Body beneath, legs and abdomen white, sprinkled with gray and brownish scales, the latter blackish at top. Types— 5 IX, 2, 07 and $ IX, 8, 08, from Prescott, Ariz. (Kunze), and cotypes in author's collection from same locality; also in collection of Mr. J. A. Grossbeck. Genus EUPITHECIA Curtis. Eupithecia exudata, new species. Expanse, 16 mm. Palpi short, stout, bushy; dark brown, with a few paler brown scales on upper ridge. Antennas stout, tufted with black along upper side so heavily as to appear serrate, much compressed, very shortly biciliate. Front and thorax yellowish-brown, a dark brown band across former at center, the latter with a small whitish scutellar spot. Abdomen stout, clothed above with coarse scales in dark and pale brown, becom- ing grayish at tip. First segment pale, second nearly black. Tufts well- developed black. Primaries produced at apex, margin nearly straight. Secondaries small, the apex extended, outer margin retreating and much rounded. Primaries yellowish brown, darkened along costa and subterminally, with a heavy sprinkling of black scales. These also mark the veins in short dashes, rather sparingly. Two pale whitish dashes across costa, one-third out, would indicate the be- ginning of basal line, but no lines are apparent crossing the wings, excepting the usual pale geminate line extra-discally. This line, somewhat clearer whitish where it crosses costa, turns outward with a slight curve, thence in a straight course, inclined basally to inner margin well within the anal angle. Subterminal line, just perceptible, soiled-whitish, ending at anal angle in a clearer white spot. Basally this spot is made more distinct by a cluster of black scales. Terminal line black, heavy, widely broken at veins. Fringes rather heavy, long, brown, darker at base. Discal dots moderate, round, distinct black. OF WASHINGTON, VOLUME XI, 1909 121 Secondaries in color and markings same as primaries; the geminate pale line, not distinct, can be traced parallel to margin. An irregular line of blade scales runs from middle of inner margin to the fine linear black discal dot. A white spot and cluster of black scales at anal angle. Terminal line black, broken at veins. Fringes pale brown, long, faintly barred. Beneath all wings a yellowish ashen, dark ashen subterminally, the pale line as above, but more clearly defined, curving regularly out from costa around discal dot, and inwardly margined with dusky scales, becoming broad and jet black at costa. On secondaries, the irregular line of black scales, running from inner margin to discal dot, is heavily marked, on one wing appearing to run through it, ending in a black spot at costa: a dark ashen basal area, and outside the pale line, is a dusky line, curved strongly outward as it leaves inner margin, thence curving to costa, hence not parallel to outer margin. Body beneath, legs, and abdomen soiled-white, thickly sprinkled with dark gray scales, the latter with two terminal segments dark, as above. Tv/v.v — Two males from Merrick Museum collection, taken at Xew I'.rishton, Pa., one IV, 2(), 03, by H. D. Merrick, the other EV, 27, 08. The latter Mr. F. V .Merrick has kindly allowed me to retain. The species seems to he rare, hut should he easily recognized by the heavv antenna! structure. Eupithecia promulgata, new species. Expanse : Male, 19 mm. ; female, 22 mm. Palpi long, dark brown, tipped with white. Antennae moderate, in male shortly biciliate, in female ciliate. Front, thorax, and abdomen above dark brownish-gray, darker brown across thorax in front and beneath abdomen. A white spot on scutel, one on third segment of abdomen at sides, and at its extreme tip. Wings broad, somewhat extended apically, with outer margins rounded, on secondaries slightly flattened from veins 2 to 6. All wings a dark gray-brown, darkened along costa and subterminally. The cross-lines are double, whitish (clear white in female) where they cross the veins, producing a mottled effect. The basal pair about one-third out run in outward curve, some- what waved, to inner margin. Intradiscal pair leave costa above the large black oval discal spot, the inner line passing in a curve just outside it to the point where vein 2 leaves cell, then with another outward curve to inner margin. Extra discal line pale geminate, rather broader at costa runs outward to vein 6, turns abruptly and proceeds, excepting a slight outcurve below vein 2, almost in straight line to inner margin. All veins are marked with short Mack dashes, a series of heavier ones indi- cating an obscure extra discal line across both wings. Subterminal line white, fine, serrate, clearly marked from costa to vein 4, ending in a large clear white spot between veins 3 and 4. Another similar 122 PROCEEDINGS ENTOMOLOGICAL SOCIETY spot anally below vein 2. Terminal line black, broken at veins. Fringes long, same color as wings, checkered. Secondaries paler basally, only intra- and extra-discal lines crossing them, the latter most distinct and parallel with outer margin. Discal dots round, black, a little ob- scure. Subterminal white line not so clear as in primaries, but the large white spots between veins 3 and 4 and at anal angle are well marked. Beneath all wings grayish ashen, the white lines reproduced as above and broader. On primaries, two or three darker patches at costa indicate the beginning of shade lines which fade out before reaching middle. Subterminal space darker. The extra discal, a series of indistinct dashes on veins as above, is clearer on secondaries, rounds out about discal spot to a point between it and inner margin, then wavy to margin. Discal dots more definite than above, black. Body beneath and legs white, with tips of tibiae and tarsi barred with dark gray. Abdomen beneath clear white, a lateral black streak on segments 3, 4, and 5 and in the male a little dusky at tip. Types — Male and female in author's collection. The male taken IV, 13, 06, at New Brighton, Pa., by Mr. H. D. Merrick, the female at Big Indian Valley, Catskill Mountains, VI, 23, 07, by the author ; a cotype female was captured IV, 30, 03, by Mr. H. D. Merrick at New Brighton, Pa., and is in the Merrick Museum. A single female specimen captured many years ago in North Carolina (no date) by Mr. Morrison, it is supposed, is in the collection of the Brooklyn Institute Museum, New York, and has been made a cotype. These are the only examples 1 have knowledge of at present. The species seems uncommon, and closely resembles \oungata Taylor, but is a shade smaller. It is readily separated from it by the long palpi, by the biciliate antennae of the male and by the white abdomen beneath ; which in voungata is a sooty black at tip. Through the generosity of Mr. F. A. Merrick I have been permitted to retain the male, which I have constituted a type in order that I might keep before me its structural peculiarities. Eupithecia albigrisata, new species. Expanse, 18 mm. Palpi moderate, rough-scaled, dark gray. Front and vertex dark gray, the scales large, silky. Thorax dark gray, white posteriorly. Fore wings, pale silver-gray, a shade darker along costa and subtermi- nally. From base to subterminal space the wings are crossed by about eight fine gray lines, indistinct except at costa and internal mar- gin, this entire space having a whitish appearance. A broken line of black scales starts from cloudy spot on costa, just within discal dot and touching it, turns backward and runs along vein beneath cell to OF WASHINGTON, VOLUME XI, 1909 123 base, also extending along vein 2 nearly to margin. Extra discal pale line crosses costa, then makes a sharp angle outward, and curves inward gently to inner margin, divided by a hair-line of gray, its outer section being pure white. Subterminal space with central pale line not white, crenulate, and its course parallel with extra discal pale line. A dark gray spot outside it at anal angle. Marginal line distinct, black, cut at veins. Discal dots large, linear, black. Fringe silver-gray, long, clouded at veins. Secondaries with about five fine gray lines, indistinct, except the one just outside discal dot, which is darkened and diffuse. From base to subterminal, which is a shade darker, the wing is whitish in color. Marginal line and fringe as in fore wings. Discal small, round, distinct. Beneath pale silvery gray, with all lines broken into dots. Extra discal pale line on fore wings evident. A dark line runs from costa to discal dot, with a dark shade line outside and parallel to it, darker and broader at costa. Discal dots as above. Abdomen with first segment whitish, second dark gray, the rest pale gray, with tufts dark gray. Legs dark gray. Type — One male from Atlanta, Ga., May, 1905; collection of author. The type is very thin in wing texture, but is in good condition. Eupithecia fortunata, new species. Expanse, 15 to 17 mm. Palpi short, barely visible beyond front dusky-slate tip and beneath white. Primaries somewhat extended at apex, broadly rounded, sec- ondaries full, rounded margin slightly flattened between veins 3 and 6. Antennae slender, barred, dark gray and white; in the male shortly ciliate. Head and all parts above dark slate, evenly mixed with whitish scales, soft and powdery in appearance, the latter clear white in a spot at posterior of thorax, along sides, and a line along dorsum of abdomen, a spot at terminus of vein 2 on primaries, the termination of a very indefinite subterminal line, and forming on primaries, basal, intradiscal and extradiscal geminate cross lines, the two latter only being present on secondaries. Basal line on primaries leaves costa one-third out, and with a small angle, curves irregularly to inner margin a little nearer base than on costa. Intradiscal makes a sharp outward angle at costa above and enclosing the round, jet-black discal dot in male, pass- ing just outside and touching it in the larger female, thence straight across wing, in general direction, but having at vein 1 a small sharp outward angle. Extra discal leaves costa three-fourths out and almost without angle sweeps boldly outward in a curve, approaching intra- discal above vein 2, where it makes a corresponding outward angle before reaching inner margin, well within tin- definite anal angle. Between these lines and the broad subterminal space the color is darker 124 PROCEEDINGS ENTOMOLOGICAL SOCIETY slate. Subterminal white line is indicated by scattered white scales, more definite near costa. Terminal line black. Fringe pale slate, check- ered with black opposite veins and having at base a whitish line. Secondaries with powdery surface as in primaries. The geminate cross lines clearer at inner margin, almost disappear costally. Intradiscal runs straight across wing, including the small black distinct discal dot. The extra discal parallel to outer margin, in other respects similar to primaries. Beneath sprinkled with dark brown and clear white scales, the pattern as above, on all wings strongly reproduced. The extra discal on all wings bordered internally and externally, with a darker narrow line of brown, and the sharply distinct, somewhat linear discal dots are black. Body, legs, and abdomen beneath with white and brown scales mixed, the latter predominating at tip of abdomen. Types — Male and female were taken at Chimney Gulch, Golden, Colo. (Oslar), V, 22, 08; also a cotype female; all in author's collection. This is the species associated by Doctor Hulst in his collec- tion at New Brunswick with the true type of Eup. subcolorata. The specimen is in very poor condition, but its strongly marked underside probably led him to believe it the same. Eupithecia conceptata, new species. Expanse, 18 to 20 mm. Palpi moderate bushy brown, tipped with white. Antennae in male liiciliate, finely serrate, with a small fascicle of fine hair springing from each tooth, in female simple strongly ciliate, as much so as is the male in many species. Wings narrow, produced at apices. Front yellowish- brown. Beneath antennae a small jet black spot and below these at orbits a white spot which apparently may join in an indefinite band across front, or may be entirely absent. Collar and vertex paler. Thorax with a broad band of dark brown across front, yellowish- brown of russet centrally, paler posteriorly. Abdomen with first and second segments nearly white, remainder with row of broken black spots on either side of dorsum, producing a pale line centrally, its general color a brownish gray. No tufts apparent. Primaries, ground- color yellowish-brown, darkened basally and subterminally by a mix- ture of dark brown and black scales, these in the female frosted witli white, producing a grayish look. Within extra discal, along vein 1, the median vein, and subcostally, occasionally to outer margin along vein 6, strongly tinged with russet. A decided dusky spot from angle of extra discal along costa to apex. The pale geminate cross-lines are outlined with black hair-lines, the basal narrow and lost in darker basal area. Intradiscal, nearly one-third out, makes a sharp outward angle below costa, another between veins 1 and 2, and touches inner margin one-half out. Another black hair-line, heavier at costa, passes outward just be\oml OF WASHINGTON, VOLUME XI, 1909 135 discal dot in a sharp curve, thence in waves basally toward inner margin close to intradiscal. The geminate extradiscal, with a sharp angle below costa, runs parallel with this line, its inner boundary line well marked and heaviest at costa. Discal dots small, oval, jet black, encircled with white scales. Subterminal white line not traceable in male, except as a white spot, and clustering black scales about it, between veins 1 and 2 at anal angle, in female, distinct, with clear white anal spot, having some black scales about it, and also in scallops of central portion. Sec- ondaries pale yellow-brown, dusky along border. Inner margin flecked with black scales, and showing the commencement of extradiscal and intradiscal lines, neither of which cross the wing. No discal dots. Terminal lines black. Fringes dusky, a pale line at base, centrally darker. Beneath uniform pale-yellowish, the extradiscal pale line outlined by black scales outwardly as points on veins. Discal dots nut clear but apparent, linear on primaries, small round dots on second- aries. Terminal line black, cut at veins, and the fringe darkened at these points. Body, legs, and abdomen beneath dusky, the latter paler with black lateral streak on second segment. 7'v/V — Male from Denver, Colo., and female from Chimney Gulch, Golden, Colo., V, 22, 08 (Oslar), with four cotypes from same localities in author's collection. Eupithecia quakerata, nc\v species. Expanse, 21 mm. Palpi moderate, stout, bushy. Antennae stout, very shortly ciliate. U'ings narrow, a little extended apically. Front, thorax, abdomen above, and wings a uniform pale-drab, darkened along costa of pri- maries, subterminally on all wings, and along inner margin of second- aries by a few scattering black scales, dusted very thinly also over the pale central portion. None of the usual cross-lines occur centrally, but a single black hair-line runs straight from costa to inner margin, a little waved, and with a very small angle at costa, crosses the usual location of discal dot and entirely obliterates it. The clear white sub- terminal line, scalloped between veins, forms above vein 2 a large white blotch, surrounded by clustering black scales, thence in a narrow line to anal angle. Terminal line black, narrow, continuous. Fringe same as ground-color, having central dusky line. Secondares without discal dots or lines, showing only at inner margin the inception of geminate extradiscal. At anal angle a small clear white dot, and black scales below vein 2. Beneath pale drab, narrowly dusky along outer margin of wings. Discal dots dear on all wings, linear, black. On primaries four indefinite dusky lines cross wing outside discal dot, the two outer enclosing the pale extradiscal, curving outward without angle, and disappearing when half across. The inner ol these lines is marked 126 PROCEEDINGS ENTOMOLOGICAL SOCIETY at costa by a jet black spot and there is a similar spot above the discal dot. Terminal line black, cut at veins. Secondaries with extradiscal out- lined in dusky dots on veins. Within these, at inner margin, appear two or three more faint dusky lines. Terminal line continuous black. Body and abdomen at base pale drab, the latter dark at tip, with a lateral black band on central segments. Legs dusky. Type — One male, taken at San Miguel, Colo. (Oslar), in author's collection. Eupithecia limnata, new species. Expanse, 22 to 24 mm. Palpi long, not bushy, dark yellow-brown, tipped with paler. Wings broad, not much produced apically, thin in texture, with margin round- ed ; in secondaries, a little flattened below vein 6. Antennae yellow- brown, stout, heavily biciliate, in male the fimbriae long and silky. Front pale yellow-brown, with a few dark-brown scales intermixed, vertex paler and without the dark central spot generally present in olivacea Taylor. All above yellow-brown, mottled with dark-brown scales. A broad band of the same color crosses thorax in front, and some examples are marked along costa with blotches of same. Abdomen with tufts and a fine lateral line of black, second segments sometimes darkened above with brownish scales. Three pale lines cross the primaries, the first narrow, rounded from costa to inner margin, is close to base, and the basal area enclosed is wholly dark brown. A broader pale line crosses at one-third out, angulate below costa, where it widens, and then irregularly to inner margin, its outer boundary line marked with dark brown scales, heaviest at costa. The extra discal pale line is most distinct, with a sharp outward angle below costa, its course thence almost straight, with an inward slope to inner margin two-thirds out, its inner boundary line of dark brown scales wavy, with an outward scallop between the veins. The central portion is thus clearly defined by these dark brown irregular cross-lines. Submarginal space broad, traversed centrally by a broad, wavy pale line, clear white sometimes, ending in a large white blotch near anal angle. Fringes long, as in all of the filmata group, of ground-color, cut with paler between veins, as is also the narrow black terminal line. Secondaries same as primaries, but more thinly scaled basally. The dark brown scales predominate along inner margin, and outline partly across wing the extradiscal pale line, and the beginning of the intradiscal. All lines lost before reaching costa. Discal dots on all wings large, linear, jet- black, and black dashes mark the veins brokenly. Beneath all parts as above in color, but paler, the extradiscal pale line evident, bordered inwardly by a narrow dark brown line and outwardly by a broad shade line of same, much waved on its outer border, limited apparently by OF WASHINGTON, VOLUME XI, 1909. 127 the convolutions of the subterminal white line above, on secondaries becoming narrow and indefinite. Body, legs, and abdomen beneath pale. Type—$ IV, 4, 03; 9 IV, 5, 03, Victoria, B. C. (Ander- son); and six cotypes in author's collection. Besides these are eleven examples, six of 'which 1 have made cotypes in the collection \J . S. National Museum. They are all males and are labeled III, 23, 03 (2) ; IV, 6, 03, Wellington, B. C. (Bryant); IV, 10, 03 (2), Victoria, B. C. (Anderson); III, 18, 03, Seattle, Wash. (Kincaid). The rest are in poor con- dition, but from these same localities. This is the species I have repeatedly referred to, particularly when describing filmata Pear, as the lachrymosa Hulst, follow- ing the opinion of Rev. G. W. Taylor, as expressed when he described a near relative in this group with its biciliate an- tennas under the name olivacea. A recent study of lachry- mosa in the Hulst collection at New Brunswick, the type of which is a male from Oregon, proves it to possess simple ciliate antennae, and therefore entirely distinct, though super- ficially it bears a great resemblance to this species. There is still another closely related species which I think I can separate on structural characters, described next in order. Eupithecia usurpata, new species. Expanse, 21 to 23 mm. Somewhat smaller, but in shape and color much as is limnata. It is best described by comparison with that species. Front darker, vertex not clear whitish, mottled, or with a central dark spot as in olivacea Say. Antennae bilicate, the cilia shorter, not so silken, with more of a tendency to separate into fascicles. Color above and beneath an even, soft, darker yellowish-brown, not mottled as in limnata, the pale cross- lines and subterminal white line barely traceable, the latter entirely lacking in one example. Discal dots linear black, small on secondaries and beneath, much less clear than in limnata, as is the case with all other markings. Abdomen pale, second segment in one example having a dark line at side, all other specimens without a trace of lateral black line, extending nearly to tip in limnata. A few black dashes centrally and along vein 1 and in type also a row of short black dashes crosM> primaries on veins, along outer border of cxtradiscal pale line. Beneath paler than above, silvery in sheen, a little dusky terminally, the lines above showing through faintly. The pattern of markings in all this group are not easily differentiated by description, though separation is not so difficult as would seem. It flies with limnata in the same localities and may yet prove a variety of it, though I do not now believe that it is. 128 PROCEEDINGS ENTOMOLOGICAL SOCIETY Type — Male is from Victoria, B. C, IV, 4, 03 (Anderson), in the author's collection, and the female type rests in the Brook- lyn Institute Museum, having been labeled by Doctor Hulst as, the type of Eup. nimbosa in error. It bears a locality label "Calif.," without date, but I doubt the correctness of this legend. It is, however, the only perfect female at present known to me. Cotypes, one male in author's collection and two males and a crippled, headless female in the U. S. National Museum. Eupithecia classicata, new species. Expanse, 20 mm. Palpi moderate, dark brown to black, tipped minutely with white, not bushy. Antennae compressed, ciliate, rather slender, pale gray, barred with black. Front and thorax dark chocolate-brown, the former crossed beneath antennae with a pale band of milky-brown or cafe au lait color which also tinges the primaries along costa and inner margin, also quite broadly along inner margin of secondaries. Abdomen above of same color, having second segment diffusely black, with tufts on three succeeding segments jet-black tipped with white. The pale-brown here in certain lights assumes a coppery gleam. Collar pure white, and across thorax in front veins a narrow snow white band, losing itself terminally in the patagia, which are tipped with white and rather long for this group. Ground-color of all wings dark leaden, lighter centrally on primaries, and basally on secondaries. Primaries rather extended, apparently crossed by a series of ill-defined narrow black lines sharply angled at costa and retreating basally in a direct course toward inner margin. A single broad jet-black band runs outwardly from costa, sharply angled just in front of discal dot and reaching inner margin about 1 mm. from base. The paler central space includes a jet-black oblique, linear discal dot and is outwardly bounded by the geminate pale line, sharply angled at costa and running in a direct line to inner margin near anal angle. This line and the subterminal white line are not very distinct. Terminal line black. Fringes leaden, mixed with brown. Secondaries show the geminate pale line running parallel to outer mar- gin, bordered on each side at inner margin with a narrow line of black scales. Two other similar lines between these and base fade out half- way across wing. Basally at inner margin is a jet-black patch of scales. A faint linear discal dot. Fringes and terminal as in primaries. Beneath silvery gray, with indications of lines as above, not very clear. Discal dots on all wings, linear distinct black. Abdomen white basally for half its length, the remainder to tip sooty black. Body and legs soiled white. Type — One male from Huachuca Mountains, Arizona, VII, 07 (Haimbach). It was presented to and remains in the col OF WASHINGTON, VOLUME XI, 1909, 129 lection of Mr. J. A. Grossbeck, of New Brunswick, who cour- teously turned it over to me for inclusion in this paper. Though not in first class condition, having no hind legs, the snow-white- collar and thoracic line present features quite apart from evcrv other species known to me. Its style of markings suggests the genus Nasnsina Pears., and it may be found, when perfect specimens are at hand, to belong there. Mesoleuca actuate, new species. Expanse, 22 to 24 mm. Palpi and front dark brown or blackish, the fomer very short, bushy. Collar, vertex, and body above much paler, by a liberal admixture of whitish with pale brown scales. Thorax paler centrally, with its double posterior tufts tipped with white. Primaries, ground-color pale ashen, tinged with yellow-brown and white. Basal line curved regularly out- ward at centre reaches inner margin nearer the base than on costa. Between this and discal space is a broad band of ground-color, centrally washed with pale roseate brown. About one-third out the internal wavy boundary line of discal space leaves costa with an outward curve, forming above vein 1 a sharp inward tooth, thence to inner margin a little more than one-third out. Base and discal cross-band black, the latter twice as wide costally as on inner margin, and filled with ringlets of paler color, one of which encloses the almost invisible discal dot. In one of my specimens the central band is dark brown. Its external line is very irregular. Leaving costa two-thirds out it makes a sharp outward tooth below it, then after a strong inward curve, two others rounded between veins 2 and 4, the upper smaller and longer. A sweep inward narrows the discal space at this point, where a small scallop is succeeded by a heavy outward protrusion between veins 1 and 2, reach- ing, with a smaller one, the inner margin about two-thirds out. The discal space is sharply bordered, both externally and in a lesser degree internally, by a geminate clear-white band following its every irregular- ity. A broken shade line of brownish or gray follows it. Subterminal space whitish or ashen, having at costa a square brownish or gray patch, below which two short jet-black lateral streaks fill in the con- volutions internally of the white scalloped subterminal line. Two other small crescents are placed diagonally above these toward apex. Termi- nal line fine black, cut at veins and often into a series of double dots between veins toward apex. Fringes moderate, gray, darkened some- what with brown, especially opposite veins. A clear white dot, appar- ently an emphasis of the subterminal hair-line, is noticeable on all the specimens before me between veins 2 and 3. Secondaries an even pale gray, marked only by the small faint discal dot and a continuation of the irregular white geminate line of primaries, rounded out from costa, wavy, but showing less definitely the double teeth between veins 2 and 4, 130 PROCEEDINGS ENTOMOLOGICAL SOCIETY reaching inner margin just within anal angle. All wings beneath silver- gray, sprinkled with darker gray scales from base to extradiscal line, sometimes outlining the discal band above and the costal apical patch more clearly. Discal dots small, distinct, black. Abdomen beneath body and legs soiled-white, sprinkled with gray scales, the latter quite heavily. Type — Male from Yavapai County, Ariz., VIII, 26, is in the collection of J. A. Grossbeck, New Brunswick, N. J., and the type female in author's collection from Chiricahua Moun- tains, near Douglas, Ariz., VIII, 23, 08. Cotypes are three females from Yavapai County, Ariz., VIII, 26; IX, 2; and IX, 8, in collection of J. A. Grossbeck, and three females from Chiricahua Mountains, Ariz., VIII, 14, 08; VIII, 28, 08; and IX, 1, 08, in author's collection. Easily distinguished by the very irregular outline of the discal space and its white border line. Coenocalpe franckata, new species. Expanse, 26 mm. Palpi short, stout, barely extending beyond front. Antennae rather stout, strongly compressed, faintly ciliate. Front a little prominent, with broad central roseate band across it, on a clay-yellow ground, the rosy scales extending to vertex between antennas and at base of patagiae. Thorax golden-yellow at front and along sides. Centrally clay-yellow fading nearly to white at scutel. Abdomen golden-yellow, with first and second segments pale yellow-white. General color above clay- yellow, shading into golden-yellow costally toward apex and outer margin of primaries and on outer third of secondaries. Along costa these scales deepen in color and become roseate toward base, broken into sections, the indication of pale cross-lines, the first quite near to base, the second one-third out. The third or extradiscal nearly two- thirds out, broad at cost A, narrowed by a sharp inward angle along its outer border at vein 7, sweeps boldly outward to vein 4, then merges into the ground-color. A broad band of black scales, faintly continued across costa, covers the end of cell from subcostal region to vein 4 and forms its inner boundary. Outwardly it is limited by a broad black band filling the angle at vein 7 extending from costa in a strong out- ward sweep, but fading out before reaching anal angle. An irregular cluster of black scales extends from apex, and often joins this band at angle. No terminal line. No discal dots. Fringes on primaries whit- ish at base, black at tip, below which they are bright pink, fading into white at anal angle. On secondaries a few black scales at apex, then white, running into bright pink at anal angle, faintly checkered with white. Without markings or discal dots. Beneath paler yellowish, the OF WASHINGTON, VOLUME XI, 1909 131 markings on primaries above reproduced in black, or by bright roseate scales thickly strigate at apex and along costa. Secondaries entirely covered with short roseate strigations, excepting a large snow-white triangular spot near end of cell, and a broad white band, running from inner margin at one-third from anal angle in a slight outward curvr. frequently ending at vein 6, when it connects by a spur with central spot. In one example a few black scales are scattered about this central spot. Fringes pale, checkered with pink. No discal dots. Body beneath and legs clay-yellow, -sprinkled with roseate scales. Abdomen as above. Types — Two males, received through the courtesy of Mr. George Franck, whose name I have given them. Taken in the Chiricahua Mountains, near Douglas, Ariz., IX, 15, 08, and IX, 20, 08. This species, about the size of formosata, has the stout wing- texture, and decided coloring of seifertii, while beneath its pattern copies the former, from which it differs in coloring. In formosata the secondaries within white line to base are strigate with black, while franckata is entirely roseate. Hydriomena regulata, new species. Expanse, 26 to 28 mm. Palpi very long, not stout, black with a few white scales above and at tip, terminal joint long. Antennae slender, compressed. Front and vertex white, washed with pale sea-green, a clear black line across front below antennae. Thorax with intermixed scales of white, black, and bluish gray, washed with green along sides, and on patagia. Posteriorly an enormous tuft or cushion of livid scales, their tips curved backward, rises 1 mm. or more in height. Across this centrally a nar- row white band runs down over scutel, first and second segments of abdomen dorsally having a narrow jet-black border on each side, and a diffuse bright orange stain, where it crosses second segment. Other- wise these parts are a soiled-white with a sprinkling of black scales, gathered along dorsum into spots basally. Primaries with widely gemi- nate, narrow black lines, marking the divisions. The basal pair barely one-fourth out form a large angle at wing centre, inclining basally as far as vein 1, below which, turning sharply outward, the outer reaches inner margin nearly at centre. The basal portion enclosed, is pale ashen, sprinkled with black scales and washed with sea-green. Intra- discals leave costa nearly half-way out, the inner with broad angle below it run in short waves inclining outward across wing, converging as they reach inner margin, a little more than half-way out. The broad band thus produced shaded heavily with black scales internally, is a bright liver color, and a narrower one of same color, crosses wing to anal angle, outside and parallel with the extradiscal. The extradiscal lines, broadened at costa, and confused below it, leave it three-fourths 132 PROCEEDINGS ENTOMOLOGICAL SOCIETY out, run in waves outward toward margin, which it approaches closely in a large scallop outward between veins 3 and 4, a smaller receding one between veins 2 and 3, below which it curves basally, thence straight to margin within the much-rounded anal angle. Discal space ashen, sprinkled with black atoms heavily at centre, but with pale blotches at costa, and near inner margin, these washed with dark green. Narrow terminal space ashen, darkened with black atoms and washed with sea-green, a paler patch at apex, above a black dash on vein 6. No discal dots. Terminal line and fringe on all wings dusky. The latter darkened opposite veins. Secondaries dusky, darker terminally. No discal dots. Terminal line and fringes on all wings dusky. The latter apex and along outer margin, showing only the extradiscal line in a black blotch at costa, and faintly across wing. Secondaries pale ashen, showing a double extradiscal waved line running nearly parallel with outer margin and rather near to it. All wings washed with yellow- brown scales, heavily at centre and outer margin of primaries. No discal dots on primaries, on secondaries, minute, black. Body, abdomen beneath, and legs pale ashen, sprinkled with dark-gray atoms. T\>pes — Two males taken in Chiricahua Mountains near Douglas, Ariz., VIII, 23, 08, and VIII, 22, 08. It has the style of markings of the sordidata group, but the soft confused cov- ering of rcflata and allies. NOTES. Eupithccia fuuwsa Hulst. Two types were recorded by Doctor Hulst under this name, a female from Amherst, Mass., and a male from South Abingdon, Mass. The former is a well-marked miserulata Gr., the latter, coagiilata Guen., a species which Doctor Hulst had not recognized. The name must therefore be dropped from our lists. Eupithccia bivittata Hulst. The Hulst type in Brooklyn Institute Museum is sierricc Hulst. It bears label "Soda Springs, Cal.,'' which is in Siskiyou County, while the recorded type came from Mendocino County. They are related species, but entirely distinct. Eupithccia affinata Pears. I am pleased to record the capture of a female of this rare species by Mr. J. A. Grossbeck at New Brunswick, N. J., VIII, 24. 08, at sugar. The unique male type taken at New Brighton, Pa., August 2, many years pre- viously, has heretofore been the only example known to me. Macaria intc.rtata Walk. (Dyar, No. 3859) should read intcr- tc.vta Walk. Metancma c.rcelsa Str. Under this name is listed siinplic- iaria Grote, as a synonym. It is a separate and distinct species. OF WASHINGTON, VOLUME XI, 1909 133 NEW CANADIAN MITES. [Arachnoidea, Acarina.] BY NATHAN BANKS. In the following pages I have brought together the descrip- tions of some new mites from Canada which form part of a considerable collection of Acarina. sent me for identification by Professor Tennyson D. Jarvis, of the Ontario Agricultural College at Guelph, Canada. Several of them represent genera hitherto unrecorded from our country. Of particular interest are some species of Ltrlaps, three of which are described from the muskrat, groundhog, and chip- munk, all similar to the L. echidintts which has recently been taken from rats in California.

OF WASHINGTON, VOLUME XI, 1909. 145 A REPORT ON MOSQUITOES AT DUBLIN, NEW HAMP- SHIRE, PARTICULARLY ON THE OCCURRENCE OF MANSONIA PERTURBANS WALKER. [Diptera, Culicidae.] BY HARRISON G. DYAR. The town of Dublin, New Hampshire, is a small collection of houses in the hilly country near the base of Mount Monadnock, to the east. The adjacent land was in use for farming pur- poses half a century ago, but has lately been allowed to grow up to a second growth of deciduous trees and conifers. Alost of the farms are now occupied as summer places by people resi- dent in the larger cities, Boston, Baltimore, Chicago, etc. The places are consequently not used for farming, but are covered with young forest close up to the houses, which are situated re- motely from each other. In the valleys between the hills run small streams, none of any size, but at numerous points are situated small to rather large lakes. The climate is cool, the fauna sub-boreal, The altitude of Monadnock Lake, the larg- est lake in the region described, is 1500 feet. Considerable trouble has been experienced by the summer residents with mosquitoes. These people, coming to the region solely for summer vacation, are not disposed to put up with the annoyance of these insects, but in many cases would seek some other place. As the town of Dublin, in common with many other places in New England, depends largely for its prosperity on its popularity with the summer visitors, the mos- quitoes prove a serious economic problem. There is here no question of danger to health from diseases transmitted through their bites. The locality is far out of the range of tropical disease carriers, and though two species of Anopheles are present, and not uncommon in suitable places, they are not generally diffused enough, nor even sufficiently locally abundant to constitute a serious menace. It is probable that under special conditions malaria could be acquired in Dublin; but in the houses occupied by the summer residents I think there is no danger whatever. The question then resolves itself into a study of the annoying species, particularly those prone to enter houses. I'nder these conditions we naturally look first to the house mosquito, Culc.v pif>icns Linn., and allies. Cnlc.r pipicns does not occur in the region. It is an imported European species, frequenting the larger centers of civilization, and in my exper- ience has nowhere penetrated into the country. The only 146 PROCEEDINGS ENTOMOLOGICAL SOCIETY species of house mosquitoes present in the region is Cule.r rest nans Theob., and that is rare, and has not been reported troublesome in any case. The region is far beyond the normal range of Culex quinquefasciatus Say or Aedcs calopus Meig., nor is there any likelihood of these being imported, as Dublin is a three hours ride by train from Boston, where the occur- rence of either of these insects is very occasional and dependent upon a chance importation from the south. The group of woods mosquitoes is well represented in the region. Aedcs stiinu/ans and its allies, the group of black- legged species such as Acdes abscrratus F.&Y., trichurus Dyar, lasarensis Felt,aurifcr Coq.,auroides Fe\t,fuscns Osten Sacken^ etc., and Aedes canadensis Theob., as well as the tree-hole inhabiting Aedcs triseriatns Say, are all present. The condi- tions for their breeding are ideal, the rocky and hilly soil hold- ing temporary pools of melting snow water in innumerable places, besides the edges of all the marshes which occur in nearly every valley not large enough to hold a lake. These places are all dry during the summer, but are typical breeding- places for the woods species. The continuous cover of low for- est makes excellent camping-ground for the adults and enables them to travel long distances without coming out into the hot fields. It would seem, therefore, that these species should be the principally troublesome ones. Such, however, is not the case. Two causes tend to produce this result. In the first place the woods mosquitoes never leave the shelter of trees for any distance and so do not enter the houses, for the majority of places have at least a small open space about the house. While one might be eaten alive by these insects in the woods, another upon the porch of a house would suffer no special inconven- ience. In the second place these mosquitoes rapidly become scarce as the season advances, since they have no second brood after the first emergence in May, or at least but an insignificant after-breeding in the case of Aedcs canadensis and A. fuscus, while the the tree-hole A. triscriatus is not an important factor. Thus by August, before which the summer residents have not arrived to any extent, the woods mosquitoes have b n greatly lessened in numbers. There remains, then, but one species as the principll source of annoyance, namely Mansonia perturbans Walk. Tne adults begin to emerge at the end of June and become abundant in July, at the time when the summer visitors begin to arrive. These mosquitoes are largely nocturnal, and do not hestitate to enter houses, coming in freely through the chimneys when OF WASHINGTON, VOLUME XI, 1909 147 the windows are screened. They bite viciously and are alto- gether disreputable in their behavior. They are widely dis- persed through the shelter of the woods and are very abundant. From these considerations it appears that the economic problem of the mosquitoes at Dublin, New Hampshire, is es- senntially concerned with Mansonia perturbans. If the nuisance caused by this mosquito were abated, the summer residents would experience little inconvenience from mosquitoes, at least in their residences, and the prosperity of the place would be promoted by the influx of newcomers. An institution called the Dublin Chemical and Pathological Laboratory is maintained by the summer residents for the con- servation of healthful conditions in the community. It is in charge of Dr. E. C. Stowell, of Boston. Dr. Stowell has been much interested in the mosquito problem, and has left no stone unturned to discover the breeding places of Mansonia pertur- hans, not only by personal effort, but by inviting examination by all the leading American students of mosquitoes. The writer first visited Dublin in August of 1908 at Dr. Stowell's invitation and made a cursory examination of the territory. In the spring of 1909 he made a visit of a few days in company with Mr. A. N. Caudell with the intention of making a complete survey, but the season proved to be not far enough advanced and the survey was abandoned. Later Mr. A. Busck was sent there and made extensive studies on the occurrence and specific identity of the woods species. In none of this work, nor at the visits of other entomologists, nor by the labors of Dr. Stowell and his able assistant, Mr. Howe, were any breeding places of Mansonia perturbans discovered. The breeding- habits of this species are peculiar. Fortunately they are now known, through the timely discovery by Mr. J. T. B'rakeley at Lahaway, Xew Jersey. Unlike all other mosquito larvae, those of Mansonia perturbans remain all winter in the mud at the bottom of suitable ponds, attached by their air-tubes to the vascular roots of certain species of grass. But few ponds present suitable conditions, so that the supply of these mosqui- toes in an *iven region generally comes from but a single source. TT is source is not always easy to discover. The writer made a third visit to Dublin in August, 1909, and was able to discover an extensive breeding place of the species. I'ossibly this is not the only source of the supply of these insects, but it seems to be the only place in which they breed at present in numbers in the immediate vicinity of Dublin. 148 PROCEEDINGS ENTOMOLOGICAL SOCIETY The locality in question is a small pond, the source of a small stream. The pond has stony shores and was evidently formerly of some depth. It is now bordered with woods and has been extensively filled by leaves and mud. It is also at least half overgrown with a layer of grass, interspersed with small bushes of Myrica. The grass forms a dense carpet with its thick root-stocks and dense vascular roots, through which, here and there, appear small spaces of water with pond-lily leaves. The whole layer is strong enough to support a man walking on it, though it is very springy, and if one stands still, water appears upon the surface and one sinks slowly. It was in the watery spaces among this grass carpet that the egg-boats of Mansonia perturbans were found, and to the roots below the larvse are attached. It is essential for such a pond to remain in an undis- turbed condition for it to make an ideal breeding place. Several other ponds were seen with similar grass coating, but in most of them the layers had been thickened by time and so densely grown up with sphagnum or even bushes of considerable size that breeding of this mosquito was no longer possible. A very large swamp has been formed by the damming of a stream to furnish power for an electric-light plant. At the upper end of this swamp a large area, many acres, of this grass occurs, form- ing an ideal breeding place, but, owing to the changes in the level in the water brought about by its use in the electric-light works, the proper conditions seem to have been destroyed. In August the water was a foot below its normal level, so that all the open spaces in the grass were dry and covered by a hard crust. Oviposition at present is therefore impossible here. However, it is not impossible that in a rainy season (the present season is a dry one) this marsh might be perma- nently flooded and breeding conditions reestablished. I am inclined to the view that practically all of the Mansonia perturbans so troublesome to the inhabitants of Dublin came from the small pond above described. Another pond with typical conditions was shown me by Dr. Stowell, but it is so small that no large numbers of perturbans are likely to be produced from it. If this view is correct, the adult mosquitoes must habitually fly at least 3 miles from their breeding place. I do not regard this supposition as at all improbable. It is of course possible that there are other breeding places in the vicin- ity not at present discovered. In fact I expect that similar ponds will be found in the more distant vicinity when the area of exploration has been extended. As A remedy for the mosquito plague in Dublin, therefore, OF WASHINGTON, VOLUME XI, 1909. 149 the draining of this pond should suffice. The complete drainage is not necessary. Lowering the water level 2 feet would prob- ably completely destroy the breeding conditions. If, after this were done, Mansonia pertnrbans should be again found in numbers, it would mean that another breeding place remained undiscovered in the vicinity. It would not be a difficult task to discover this, for breeding places in the right condition for this species are few and easily recognized, now that the condi- tions are understood. The following is a list of the species of mosquitoes taken at Dublin, N. H., by Mr. Busck, Dr. Stowell, and the writer : Anopheles quadrimaculatus Say. Aedes fuscus Osten Sacken.

This report was submitted to Dr. Stowell, who commented as follows : "I think you rather understate the amount of house annoyance caused by the woods species during June. They annoy on the verandas and come into the house, as I think Mr. Busck will corroborate. But as a cause of dis- comfort they cease to be important after the fourth of July, except on very still, warm nights. As they decline in impor- tance, the Mansonia perturbans appears and almost at once be- comes a fierce and obnoxious pest. The first one captured this year, you remember, was on June 25, at my house. Its prin- cipal hours for activity are from 7 to 9 in the evening and just before dawn, say from 3 to 5 A.M." *This will be described in a forthcoming paper with Mr. F.

[Coleoptera.] BY FREDERICK KNAB. Among certain forms of Chrysomelidse the imago takes on an entirely different appearance with the attainment of sexual maturity. Either new colors are added to the existing pattern or there is a complete change in coloration. These colors are not acquired as the result of the more or less gradual chiti- nization and pigmentation which follows eclosion ("Aussfarb- ungsprozess" of the Germans) hut make their appearance only with the development of the sexual powers. This matur- ing of the sexual powers may be a matter of months and often it only comes about with the advent of another season, for most Chrysomelidae are single-brooded and do not become sex- ually mature until after they have hibernated or aestivated. Perhaps it would be more exact to say that the physiological changes which determine sexual activity take place during the resting period (hibernation or aestivation ). One of the most striking examples of color-transformation of this character has been studied by Caulfield in a northern species of Cassidini; its significance, however, appears to have been wholly overlooked. The beetle in question is Physonota helianthi Randall. The difference between the parent beetles and the new generation produced from them is so great that Caulfield very naturally concluded the insect to be double- brooded and dimorphic.* l>ut further observation demon- strated that this insect is single-brooded and in the course of time completely changes its appearance. f The beetles which appear in the spring or early summer are brilliant golden green and so they remain until they copulate, lay their eggs, and final- ly die. The offspring of these golden green parents are wholly different in appearance. After emergence the pronotum and elytra are shining creamy white with translucent marginal portions and with five black spots upon the pronotum ; soon, with the progressing chitinization, the elytra change to a dull blackish color with irregular ivory spots and blotches upon them. In this sober garb the beetles may be found upon their food-plant during the later part of the summer and in the autumn; they feed but little and show no sexual desires, and it is in this state that they go into hibernation. When the beetles reappear in the following spring they have assumed the *Can. Ent., vol. 16, p. 227 (1884). fCan. Ent., vol. 19, p. 73 (1887). 152 PROCEEDINGS ENTOMOLOGICAL SOCIETY brilliant green coloration of their parents and they are then act- ive and intent upon reproduction. Dr. Dimmock and the writer have corroborated Caulfield's observations by rearing the beetles from the eggs and carrying them through to the following season. Transformations of a similar character have been observed in certain species of European Cassidini, but their correlation with the physiological changes of the reproductive period ap- pears never to have been suspected. A much less obvious case is that of another American cassidid, Chelymorpha argus Lich- tenstein. This beetle at first, shows an ochreous yellow ground- color above, and it is not until it issues from hibernation and is ready to reproduce that it shows the characteristic dull red ground-color. Incidentally it may be mentioned that at Winnipeg, Manitoba, the writer found a race of Chelymorpha argus which is ochreous yellow when sexually mature. Similar changes occur in certain Chrysomelini when sexual maturity is acquired. A striking case is that of Zygogramma signatipennis Stal, which the writer found abundant upon a large composite plant at Cordoba, Mexico. During the winter months the beetles could be found but sparingly upon their food-plant and appeared to be very inactive. At that time the ground-color of the elytra was a dull creamy white. With the advent of warm weather and the rains the beetles became abundant ; they were now active and many pairs were observed in copulation. The ground-color of the elytra had now changed to bright green-gold. In certain of our native species of Calligrapha the ground-color of the elytra is at first creamy white, and this takes on a silvery luster when the beetle "becomes sexually mature. In Calligrapha rhoda Knab the contrast is enhanced by the addition of red to the elytral pattern with sex- ual maturity ; this change takes place in a still more striking manner in Calligrapha roivena Knab. As these beetles have been described in a previous article it would be superfluous to go into the details of coloration. Tower in his book on evolution in the genus Leptinotarsa,* proposes names for certain Mexican forms of this genus which he claims to be new. He states that these species show colors in life which disappear after the death of the insect and that these colors are of specific value. Doubtless in these cases also the colors in question are correlated with the sexual functions, for in all the cases previously cited, the nuptial colors *An Investigation of Evolution in Chrysomclid Beetles of the Genus Leptinotarsa. (Pub. No. 48, Carnegie Institution of Washington, 1906.) OF WASHINGTON, VOLUME XI, 1909. 153 disappear with death, as they are said to do in these species of Leptinotarsa. Unfortunately Tower has not specified what these colors are and how they are distributed. Should these colors prove to be of the physiological character indicated, per- sons studying these beetles at different seasons would naturally conclude that the differences in coloration were of specific value ; or even the same individual, in ignorance of their trm- nature, would be led into error. Cases of nuptial colors occur in certain species of Halticini, although they appear to be much less frequent in this group than in the Cassidini or Chrysomelini. A conspicuous example is Disonycha quinque-vittata Say, a common species upon wil- lows in many parts of North America. These beetles, when found in the late summer have pale yellow elytra with narrow black longitudinal stripes. When the beetles emerge from hi- bernation the following spring the elytra show in addition a large amount of crimson, disposed in broad stripes in the intervals between the black lines. A Mexican halticid, Homo- phccta abdoniiiialis Chevrolat, which the writer found common at Cordoba, develops nuptial colors. During the winter months these beetles were frequently found upon their food-plant. They then had dull bluish black elytra, while the pronotum and most of the legs were a pale ivory-yellow. When the season of sexual activity arrived, with the rains and the warm weather, the pronotum and the legs changed to a delicate rose- red, while the elytra showed a peculiar blue sparkle. No indications of nuptial colors have been found in the two great groups of Camptosomata and Eupoda. While it is true that our knowledge of the biology of these groups is very in- complete, these groups, and particularly the one first mentioned, stand apart in many ways and one can hardly expect close correspondence in the more specialized traits. What does cause surprise is that the Hispini, which are so intimately linked with the Cassidini, show none of the remarkable color-changes so frequent in the latter group. But this may be due wholly to our incomplete knowledge, and perhaps, when the tropical forms have been investigated, this phenomenon will be found among the Hispini also. These notes demonstrate how meager is our knowledge of the biology of this important group of beetles. Our literature of economic entomology abounds with more or less extended notices of the injurious species, yet it is rare to find an original observation recorded. The accounts are mostly borrowed from earlier authors, and such additions as are made, from scattered records and without critical knowledge, are, more often than not, inaccurate and misleading. 154 PROCEEDINGS ENTOMOLOGICAL SOCIETY THE IDENTIFICATION OF CULEX CYANEUS FABRICIUS. [Diptera, Culicid?e.] BY FREDERICK KNAB. Theobald assumed that the Culc.v cvancns of Fabricius is identical with Williston's Haeinagogns spleiidens.* Although it is evident that Theobald had not gone beyond a cursory perusal of the original description, this identification was gen- erally accepted. To the writer the original description seemed to conflict with this identification in that it indicates a mos- quito with uniformly white sides of the abdomen. This type of coloration is characteristic of the Sabethini and so are the long legs indicated by Fabricius. Very few mosquitoes of the metallic blue color of Culc.r cyaneits are known, and in view of the recent large collections of Culicidse it seems im- probable that Fabricius had before him a species that has remained unknown to subsequent workers. In considering these points Dr. Dyar and the writer thought that most probably the mosquito in question was identical with Sabeth- oides nitidus Theobald (=S. confusus Theo.) and published this opinion ;f however, until the type had been examined, this identification could not be more than tentative. The opportun- ity to definitely identify this mosquito came in 1908, when Mr. Busck visited Copenhagen, where the type is preserved in the Royal Zoological Museum. Mr. Busck examined the type at our request and what he found showed that our determination was incorrect. The speci- men has a much swollen proboscis, while in Sabcthoides nitidus, and also in Haemagogus, the proboscis is slender. The abdomen is blue above, silvery below, not banded, and this indicated a sabethid ; but Mr. Busck, who examined the spec- imen with a hand-lens, could find no sete on the metanotum. Moreover, he found that on the front legs, the only ones remaining, the claws are toothed near the middle, a condition we had not found in any of the many sabethids we had studied. Yet we could not find that there was a blue culicine with swol- len proboscis, and it seemed inconceivable that Fabricius had a mosquito which has since remained unknown. A review of all the blue mosquitoes with reference to the proboscis led inevitably to Sobethes. and as in the Fabrician type the middle legs, which in that genus bear the characteristic cilia- tion, were missing, it seemed probable that cyancus belongs to *Monograph Culicids:, vol. 2, p. 238-241 (1901). fProc. Biol. Soc. Wash., v. 19, p. 168 (1906). OF WASHINGTON, VOLUME XI, 1909. 155 Sabethes. Two points, however, the toothed claws and the absence of metanotal setae, threw a doubt upon such identifica- tion. It seemed reasonable to suppose that Mr. Busck, in his examination with a hand-lens, had failed to mid the delicate setae on the metanotum ; but that still left the toothed claws to be accounted for. In this extremity we applied to Dr. I loving, of the Copenhagen Museum, and he kindly reexamined the type. The points ascertained by Dr. Hoving are as follows : (1) Metanotum undoubtedly with set;e ; (2) antennre plumose. the joints long, as in Sabethes; (3) palpi very short, hardly one-fifth the length of the proboscis — intact, without trace of breakage; (4) claws of the fore legs undoubtedly toothed, each claw with a small but distinct tooth near the middle : (5) wing with the posterior cross-vein nearer the apex of the wing than the anterior cross-vein; (6) wing with the scales of the veins broad, obliquely truncate. To these characters must be added the following, determined by Mr. Busck in his exam- ination of the type; (7) Abdomen blue above, silvery below- no trace of banding; (8) proboscis much swollen apically ; (9) wing with the second marginal cell very much longer than the second posterior cell. All these characters fitted Sabcth 'S locuplcs Rob.-Desv., as known to us, perfectly, with the one exception of the toothed claws. As the Fabrician type is undoubtedly a sabethine, and we had only female specimens of Sabethes before us, it seemed practically certain that the Fabrician specimen is the male of Sabctlics locuplcs. It is true that in the descriptions of male Sabethes available to us the front claws are stated to be simple. These descriptions, how- ever, are by Theobald, an author who had, in our experience, proved to be unreliable in such details. While everything pointed to an error in Mr. Theobald's statement, the questi< m could not be considered settled until a male Sabetlics had been examined by someone else. The opportunity came with Dr. Howard's visit to Europe the past summer, and at our request he examined the material in the British Museum. Dr. Howard, with the use of the com- pound microscope, found that in the(male of Sabethes locuplcs the claws of the front feet have a small tooth at about the middle. Thus the question is settled beyond a doubt: Culc.v cyaneus Fabricius is identical with Sabethes loci/pies, upon which Robineau-Desvoidy founded his genus, and with Culc.v rcinipcs Wiedemann. It should therefore be known as Sabetlics cvaneus Fab. Fabricius did not mention the 1110-1 obvious character of the species, the ciliate middle legs, be- 156 PROCEEDINGS ENTOMOLOGICAL SOCIETY cause, without a doubt, the specimen already had those legs missing when it came into his possession. Wieclemann had the type before him when he prepared his Aussercuropdischc sweiflugelige Insektcn and in such cases he gave supplementary notes, in addition or correction of the short Fabrician diag- nosis; that he does not mention the ciliation of the middle legs is further proof that those legs were missing at that time. It may appear strange that Wiedemann failed to recognize the identity of Cnlc.v cyancns Fabricius and his Citlc.v reuiipes, described in the same volume. The description of Culc.v rcniipcs was, however, added in the third supplement (Fernere Nachtrage) of the first volume of the above named work, and it was drawn up at a later period when he no longer had the Fabrician type before him.

XI OCTOBER-DECEMBER, 1909 No. 4 MEETING OF JUNE 10, 1909. The 232d regular meeting \vas held at the Saengerbund Hall, 314 C Street, X.W., the Society being entertained by Mr. A. L. Quaintance. President Heidemann presided and there were present Messrs. Burke, Cauclell, demons, Dyar, Gahan, Gill, Heide- mann, Hopkins, Knab, Phillips, Popenoe, Quaintance, Schwarz, Smythe, Ulke, and Viereck, members, and Messrs. Peairs, Snodgrass, and Wall, visitors. In the absence of the recording secretary, the corresponding secretary was asked to act in his place. An invitation of Mr. J. M. Lawford to meet at his home in Baltimore for a July meeting was presented to the Society. It was decided not to hold summer meetings, and the invitation was accepted for the regular October meeting. The cor- responding secretary was instructed to write Mr. Lawford to find out if this would be convenient for him. Mr. Caudell presented a paper entitled "Some Notes on Orthoptera," in which he discussed the validity of varietal names, no one of which bears the specific name as a varietal name also. He cited several cases of this kind and proposed changes. The paper caused considerable discussion, which was engaged in by Messrs. Snodgrass, Knab, Schwarz, Gill, and Hopkins. Dr. Hopkins objected to the use of subgeneric names. Dr. Gill cited numerous cases in which old genera ru-d been combined into a single genus. I.V.I 160 PROCEEDINGS ENTOMOLOGICAL SOCIETY Mr. Banks's paper on "New American Pseudoscorpions" was read by title. Dr. Phillips introduced Mr. Snodgrass, who exhibited his drawings on the anatomy of the honey bee, Apis mellifera, and explained them. Much of the work done previously on this subject has been found to be incorrect or incomplete. Dr. Hopkins congratulated Mr. Snodgrass on his work, which he considered as an advance over anything on bee anat- omy that had been done previously. He thought that the detailed drawings were very valuable, but that it was probable that the interpretation would not be accepted by all workers on anat- omy. The paper was further discussed by Messrs. Caudell, Quaintance, Gill, and Phillips. Dr. Hopkins exhibited living specimens of Chermes forming galls on the flower buds of the red spruce, Picea rubens, and a colored drawing of the galls. The following papers were accepted for publication : ON THE BEE-GENUS CENTRIS. / [Hymenoptera, Anthophoridse and Euglossidse.] BY C. SCHROTTKY, Puerto Bertoni, Paraguay. In Zeitschr. Hym. Dipt., vol. v (1905), pp. 23-26, I pointed out the systematic position of this genus in a paper entitled "Was ist unter der Gattung Ccntris Fabr. zu verstehen?" As it seems, my views have been misunderstood by several recent American writers ; therefore I think it useful to review briefly the history of this genus. It was created by Fabricius for a number of mostly Amer- ican bees. Although its type species, Centris dimidiata, stands and always stood with the Euglossidae, the genus has been removed to the Anthophoridce, because, perhaps, people thought otherwise in older times than we do. Surely none of the later anthophorid Centris has "clypeo gibbo, tibiis posticis incrassatis, compressis. ciliatis" as true euglossid Centris have. It is only too clearly seen that the later mono- graphers, Frederick Smith (1874), Heinrich Friese (1900), and with them the greatest part of the recent apidologists, follow the footsteps of Lepeletier blindly without even becom- ing aware of the mischief they introduce thus in entomology. Lepeletier was the first who gave to Centris the wrong limits OF WASHINGTON, VOLUME XI, 1909. 161 in the Anthophoridse in his Histoire Naturelle (1841). Spin- ola very soon protested against this interpretation of the Fabrician genus, but his voice was not heard. In "Historio Fisco y Politico de Chile," Fauna, vol. vi, p. 167, Spinola gave a full argumentation against Lepeletier's views and showed that the genus Enlcma Lepeletier (englossid) falls into the synonymy of Centris Fabricius, and that Centris Lepeletier must be called Hem isia Klug (anthophor id ). It is pos- sible that Frederick Smith, when he monographed these genera, overlooked the remarks of Spinola, though they were repeated elsewhere. After that it had scarcely been touched till Delia Torre's Catalogue, where it stands as Smith left it. In the last years I already used the names correctly, but in the quota- tions of my papers by Friese, Ducke, Strand, and others the wrong names always reappear. The consequence is that one who is not specialized in these groups quotes correctly Centris among the Euglossidae and describes an anthophorid, etc., as Mr. I. C. Crawford does in "Some Costa Rican Bees," (Trans. Amer. Ent. Soc. xxxn, 1906, p. 157-163). The names must stand as follows : Family ANTHOPHORIDyE. Genus HEMISIA Klug, 1807.

Dorsal and lateral spaces broad, subventral space narrow, contracted. Ridges very slight, the subdorsal ridge indicated by the change in direction in the slope of the body, which is rounded gradually ; lateral ' and subventral ridges more distinct, approximate. Outline from above somewhat dumb-bell shaped, the central area being a little constricted and the ends from which the long horns arise enlarged. The effect is heightened by the coloration, the purple band being enlarged over the extremities. Warts produced into fleshy prominences, unequally PROC ENT. SOC. WASHINGTON VOLUME XI, PLATE XIV > w * * \. •• . « :- . LARVA OF CNIDOCAMPA FLAVESCENS WALK. OF WASHINGTON, VOLUME XI, 1909. 163 elongated ; in stage I bearing a few slender setae ; after the first molt, the subdorsal and lateral rows covered with numerous urticating spines, the subventral row rudimentary, represented by two \\ setae. Of the subdorsal row, the "horns" on joints 3 to 5 and 11 to 13 are long, those on joints 6 and 10 rudimentary, the ones on joints 7 to 9 much shorter than the long ones and equal to each other. Of the lateral row, the horn of joint 5 is absent, of 3 'much shortened, while those of 4 to 11 are longer than the others. Depressed areas very feebly developed as slight irregular pits, partially free from skin spines; the dorsal row (1) paired, the subdorsal (2) smaller, scarcely distinguishable; of the lateral rows, the lateral (4) is large, rcniform, oblique, forming a distinct shallow pit, the lower intersegmental lateral (6) very small and close to (4). In the contracted subventral space the two large rows (7 and 8) are minute, but in a common elliptical depression. At the last molt the length of the horns is considerably reduced, while the coloration becomes fully developed. The small, detachable skin-spines, or caltropes, occur in patches on the lateral horns of joints 6 to 12 and on the subdorsal horn of joint 13. No detachable spine patches are present. The larva falls in "Type 2" (Dyar & Morton, Journ. N. Y. Ent. Soc., in, 146, 1895), but forms a separate section. The "end-spines" being lacking, throws it with the generalized forms of Euclea and with Adoneta, but the subdorsal horn of joint 8 is not differentiated as in all these. In the horn- structure it more nearly approaches Sibinc, in which, however, the horn-formula is different, for the subdorsals of joints 6 to 10 are there uniformly suppressed, whereas in the present type those of 6 and 10 only are suppressed, those of 7 to 9 being fairly well developed. There is also a peculiar irregularity of development of the long horns at the extremities. AFFINITIES, HABITS, ETC. The genus Cnidocampa, with its one species, flavescens, is a somewhat isolated form of peculiar development. It appears most nearly related to Miresa. In the adult of this genus the antennse of the male are pectinated on the basal third, while the larvae (of the two species known to me, albipuncta Herrich- Schaeffer and argentifera AYalker i posses long end-horns, short side-horns, the central subdorsals (joints 6 to 10) sup- pressed, end-spines apparently undeveloped. Cnidocampa lias lost the pectinations on the antennae of the adult, and is thus a modified form of Miresa. The larva, however, is les^ specialized than Miresa, having the subdorsal horns of joints 164 PROCEEDINGS ENTOMOLOGICAL SOCIETY 7 , to 9 distinct, although essentially of the same type. The coloration of the Cnidocampa larva is less specialized than that of Mircsa, its purple and green suggesting our Sibinc, though the pattern of dumb-bell shape is unlike anything found in America. It is, however, apparently not an unusual device in Asia, the figure of the larva of Orthocraspeda trima Moore showing a similar pattern. There is, however, no close rela- tion between Orthocraspeda and Cnidocampa structurally, cither as larva or adult. The young larva of Cnidocampa is without defined color- ation, the pattern being gradually developed during ontogeny, without any sudden changes. This indicates a primitive con- dition, and undoubtedly the coloration is of an ancient type, as shown by its appearance in Orthocraspeda, a phylogen- etically much older form. It is of a warning nature, the bright and conspicuous markings being accompanied with well- developed urticating spines upon the fleshy horns. The larvae spin hard cocoons upon the twigs of the trees upon which they have been feeding, usually in the forks of the smaller twigs. These cocoons overwinter, and the adults issue in the spring. The time of emergence varies with the latitude. Fernald found them to emerge in Massachusetts in the latter part of June and first of July; Fixsen records their emergence in Korea from the 18th to 26th of July. Some specimens overwintered at Washington, brought as larvae from Massa- chusetts and placed upon trees in the open, emerged June 1, while others from north China, also overwintered at Wash- ington, emerged the last of May. The species is generally single-brooded, but it may be double-brooded in the more southern part of its range. The early emerging specimens at Washington produced larvae which matured, spun, and issued the same season, producing adults again in August. The range of the species, as given by Leech, is Amurland, Japan, Korea, central and north China. The species is easily exported, as the hard overwintering cocoons not infrequently occur upon fruit or ornamental trees and their peculiar appearance does not suggest that they are the work of an insect. Fryer remarks on their resemblance to birds' e,^>. while Dickerson thinks that they look like leaf-buds. Either simile appears to me rather far-fetched. The general mottled coloration rather resembles that of bark, especially upon knot- ted twigs with patches of lichen, though there does not seem to be any very special adaptation for concealment, the exceed- ingly hard nature of the cocoon itself rendering such a thing superfluous. OF WASHINGTON, VOLUME XI, 1909. 165 The cocoons have been found introduced upon fruit trees in Hamburg, Germany (Kraepelin), San Francisco, California (Dept. Agriculture), and New York(Joutel) ; but in Massa- chusetts they were introduced in sufficient numbers so that the species reproduced and became established in a small district in Dorchester in the suburbs of Boston. The place is entirely built up to houses, but there- are many open spaces with trees and shrubbery, as well as trees along the streets. A park of considerable extent (Franklin Park) is in the c! vicinity. Conditions are therefore favorable for the contin- ued existence of this interesting species in America; but unfortunately Dr. H. T. Fernald, in an excess of economic zeal, which we consider premature, destroyed large numbers of the cocoons, for fear that the insect might become a pest. What effect this action has had upon the continuance of the species we do not know. It is to be hoped that the moth has not been exterminated. Some thirty of the cocoons were allowed to emerge in the open in Washington and many e and young larvae were subsequently observed. All, however, died in the third or fourth stage, probably because the location was too dry and open. The climate can scarcely have been too warm, considering the distribution of the species in Asia. I have several times observed young Cochlidian larvae to die when placed upon trees in the open that I had thought favor- able to them, but which proved to be dry and sunny. The moths, in ovipositing, doubtless avoid such situations. The eggs laid at Washington, while deposited by moths issuing at large, were necessarily laid in the vicinity of the place where I had placed the cocoons, and it was evidently an unsuitable one. The eggs are laid singly upon the undersides of the leaves, and the larvae live in the same situations, not moving greatly. yet passing from leaf to leaf occasionally. They eat at first the parenchyma of the leaf from beneath in little patches, later the whole leaf from the tip, all as in the manner usual in the family. Eight stages occurred in my specimens. The larvae do not feed in the first stage. The adults rest with the tip of the abdomen against the support, the legs extended, in the manner of our Natada nasoni Grote and other Cochlidians. Their period of flight is short, as no nourishment is taken in the adult state. The species appears to be common in its home. Grae-cr found the cocoons "sehr gemein" at Blagoweschtschensk, Amurland. where he found cocoons on all deciduous tr< especially on birches, in all the gardens and in the forest; 166 PROCEEDINGS ENTOMOLOGICAL SOCIETY while du Buysson .reports: "une annee, M. 1'abbe de Joannis en re tit trois mille cocoons, recoltes par des gamins.'' One reason for the apparent abundance is the conspicuousness of the cocoons, and it may be that the three thousand cocoons that the abbe's sharp-eyed boys collected represented prac- tically all the specimens of this species in the place, which would not be a large number. The principal parasite appears to be Chrysis shanghaiensis Smith, which parasitized one-tenth of the cocoons above referred to. This species seems not to have been imported into America with its host. •The peculiar cocoons are one of the most noticeable features of the life history. Placed conspicuously upon the branches of the tree, their grotesque coloration at once attracts attention. In spinning the cocoon the larva, after selecting a suitable position, spins a few supporting threads ; but the anterior ventral surface of the larva itself furnishes the main support for the first film. The larva bends backward and spins back and forth across its thoracic feet, gradually creeping upon the film as it forms. When the outside film is complete the larva strengthens it, continually turning about. The thread is dark brown ; but during construction the larva voids an opaque white fluid from its anus which gives the white ground color. The' peculiar brown markings are caused by bands of thick silk through which the white fluid has not penetrated before the whole solidified. CRITICISM OF PKKYIOVS 1 )KSCKI I'TJOXS. Graeser's description of the larva is very brief, and mentions only the coloration, so that one can not tell therefrom whether the larva belongs to the spined or smooth types. This is especially important in this case, since the structure of the antennae of the male adult is deceptive. My description was made from inflated larvse in which the color is largely lost. I failed to note the caltrope spines. which were largely removed in the specimens. Dr. Fernald's description is rather long, but made from larv?e taken from the cocoons, whose shape and colors both \\ I.T]orK>s. with a white subventral edge line. Diffuse blue lateral patches "ii joints 4, 5, 6, 10, and 11. Skin wrinkly-shagreened. Depressed spaces slight, with glandular centers indicated laterally by colorK-ss dots, not shown dorsally. Length, 14 to 18 mm. : another specimen, 13.5 to 19 nun. Duration of the stage, live to seven days. Stage Till. — Subdorsal horns of joint 3 short; of 4 longer; of 5 longest; of 6 and 10 minute; of 7-9 very small; of 11 like that of 4; of 12-13 small, about like those of 3. Lateral horns of joint 3 vi-ry small; of 4 like the subdorsals of that joint; of 6-10 a little smaller; of 11 and 12 equal to the subdorsal of 12. Horns greenish yellow, tin- spines yi-ll along joints 9 and 10 on the level of tubercle Hi, where it is lost; feet and subventral areas of joints 6 and 10 heavily brown mottled, of joints 7 and 8 very slightly so; a green subdorsal oblique line, the pair 172 PROCEEDINGS ENTOMOLOGICAL SOCIETY forming a V-shaped mark, begins on joint 9 posteriorly and runs to the posterior edge of joint 11 laterally, being broken at the incisures; there is also a narrow dorsal line of the same color from joint 9 to joint 13, wh'ch is indicated on joint 8 by a pear-shaped small orange blotch between the points of the lateral finger-shaped processes ; sides of the horn posteriorly heavily brown mottled, as well as a subventral patch on joint 6 and the area about the spiracle of joint 11. Anal feet small, slender, divergent, brown-mottled. The area around the spiracle of joint 5, especially at tubercles Hi and iv, is roundly protuberant, causing a collar-like appearance of this joint when seen from above. As compared with the larva of Hy par pax aurora Smith & Abbot, the general pattern of coloration is similar. The head is larger in the present insect and distinctly exceeds joint 2. The hump on joint 5 is here produced into a horn, but the humps on joint 12 are the same in both. The sides of the thorax are green in both, with brown dorsal stripe. The subdorsal white markings in aurora are all broadened and rounded, filled with brown mottlings, whereas in the present species they are narrowed, clear of filling, and obliquely placed. Tn aurora the rounded white subdorsal markings adorn the abdomen for the entire distance between the two dorsal humps, whereas in the present species these markings are obsolete on joint 6, then brought out strongly in the peculiar finger-shaped mark on joint 8, finally replaced posteriorly by the broken V-shaped line. Except for its bizarre pattern, the larva might readily be taken for a species of Schizura, as is indeed the case with Hyparpax aurora. OF WASHINGTON, VOLUME XI, 1909. 173 DESCRIPTION OF THREE NEW AMERICAN MOSQUITOES. [Diptera, Culicidae.] BY HARRISON G. DYAR AND FREDERICK KNAB. Wyeomyia intonca, new species. Male. — Prothorax, mesonotum, and scutellum clothed with blackisli scales with blue and bronzy reflections; abdomen with the venter white. separated from the dark dorsum in a straight line; occiput clothed with dark scales; proboscis of moderate length, dark-scaled; mid tarsi with the tip of the second, the third to fifth jo'nts white, except for a narrow area along the upper side ; fore and hind tarsi dark. The genitalia have the outer angles of the side pieces produced in the form of a long arm, twice as long as the basal part of the side piece, each with three distinct tubercular areas bearing dense hair tufts ; clasp filament rather long, but slender and simple, with angularly expanded tip. Type — No. 12744, U. S. National Museum. One male, Empire, Canal Zone, Panama, March 2, 1009, bred from a larva in the water in the leaves of a Bromeliaceous plant on a fallen tree on the bank of the Comacho River (A. H. Jennings). The species is nearly allied to W . circumcincta D. & K., but differs in the coloration of the tarsi and in the male genitalia. The female presumably has all the tarsi black. Wyeomyia rolonca, new species. Male. — Occiput, prothorax, mesonotum. and scutellum clothed with dark scales ; abdomen with the colors separated on the sides in a straight line ; proboscis long and slender, expanded at the tip ; mi'd tarsi with a narrow white line on the first joint below, the stripe becoming wider distally, the third to fifth joints distinctly white below; hind tarsi with the fourth and fifth joints white below, narrowly interrupted at the tip of the fourth, a small white spot at the base of the third joint. The male genitalia are of the type commonly found in the Bromelia Wyeomyia, the clasp filament with long slender stem its tip expanded and trilobed, the mid lobe broadly expanded, the side lobes each narrow, with sharp, pointed tips ; the mid lobe is crossed by a corrugated area bearing a row of spines, and from the lower termination of this area a minutely pilose filament projects. Type — No. 12745, U. S. National Museum. One male, Upper Pequini River, Panama, March 24, 1909, two miles up the Rio Juanita, bred from a larva in the water 174 PROCEEDINGS ENTOMOLOGICAL SOCIETY in the leaves of an arboreal Bromelia in which the larvae of Anopheles crusii were also found (A. H. Jennings). The speceis is allied to W. celaenocephala D. & K. and /['. hapla D. & K., but differs in the coloration of the tarsi. The female presumably has the tarsi marked as in the male. Aedes thibaulti, new species. Male and Female. — Proboscis moderate, clothed with black scales ; palpi short in the female, longer than the proboscis in the male, black- scaled; claws of the tarsi toothed; legs black, the femora white beneath at the base, the tips narrowly white ; abdomen black-scaled above, with lateral triangular basal segmental white marks, but without dorsal banding, except narrowly in the male; mesonotum clothed with black scales on the disk, the sides with golden yellow scales, broadly on the frontal half, narrowly behind, forming a conspicuous angulation of the median dark band; occiput clothed with black and yellow scales intermixed, the dark scales forming a sublateral patch on either side. In the male genitalia the side pieces are long and slender, with both subapical and subbasal lobes, the latter bearing setae but without a large distinct spine ; clasp filament slender, with a long terminal spine. Harpes rather small, their margins thickened and revolute, but without the usual terminal teeth. Harpagones with thick columnar stem which bears an apical prolongation clothed with minute pile. The terminal filament thus arises from a short separate limb, not as long as the pilose branch ; the filament is short, broadly rounded with an inner rounded projecting lobe. The unci are unusually distinct, forming a basal cylinder, but not strongly chitinized. Basal append- ages small, rounded, setose. Type— No. 12746, U. S. National Museum. One male and one female, Scott, Arkansas, April 27, 1909 (J. K. Thibault, Jr.). The species falls in the table with Aedes aurifer Coquillett, but differs in the pattern of coloration of the mesonotum. while the male genitalia are of a very different type.

All these color differences might, however, be individual in this group, where the color and markings are quite variable, but the claspers of the male genitalia are very different and the two species are undoubtedly amply distinct.

Braun, and which he had criticized at a former meeting of this Society, Mr. I'usck showed a letter just received from the eminent authority on Microlepidoptera, Mr. Edward Meyrick, of England. Mr. Pmsck referred to his own views, already published ( Proc. Ent. Soc. \Yash.. xi. <>()-\02). and was disappointed to find from the present letter that Mr. Meyrick did not agree with them. The letter was in part read to the Society by Dr. Dyar, as follows : "My criticism of your argument would be that it is ol no effect, because you have based it on an assumption of phylo- gcny t which may or may not be correct, but certainly is doubt- ful, and very probably incapable of proof) instead of on an observed structural fact of indisputable phylogenetic impor- tance. In other words, it is proved that the group with the additional vein is older than the typical group; you assume that the Hat-larvae group has arisen from beneath this older group, whereas this is not proved and until you can show the connecting links you have no right to use it in definition. It is now generally admitted that a new type of structure asso- ciated with habits, such as those of the flat-larvae group, ma\ arise by a sudden mutation and need not involve the existence of a prolonged ancestry, showing gradual change and diver- gence, and therefore this group may in my opinion have' 188 PROCEEDINGS ENTOMOLOGICAL SOCIETY originated above instead of below this older type and anyone holding the contrary view must prove his case. Your argument about the Cycnodioidca is open to the same defect." Mr. Busck said he prized highly the friendly criticism of an authority like Mr. Meyrick, whose excellent work was the foun- dation of the modern classification of the Microlepidoptera. He was anxious to have these contrary views, privately com- municated, made known, so as to get as fully elucidated as possible the important principles underlying the concrete ex- amples under discussion. He wished to present them without comment at present, except for the statement that he still held the opinions expressed in the above-mentioned paper and hoped shortly to present additional evidence in substantiation of them. Dr. Howard said that the two types of larva1 found in the genus, the flat and the round, were very distinct, and he thought Mr. Busck's classification to be the more natural one. Dr. Dyar said that there was always danger in relying upon any single character, however good in general, and he thought that this might apply to the larvae in this instance. Mr. Busck, however, pointed out that the division of the genus by the flat and round larvae was not founded upon a single character, but was marked in all stages, even the adults having a different pattern of coloration, as he had already- shown. The venational difference relied upon by Miss Braun and supported by Mr. Meyrick consisted only in the coal- escence of veins already stalked, and is simply a character of specialization, without fundamental importance.

He thought that they were in fungi as a good hiding place, and that often he had found aradids under the scales of pines sucking moisture, where he could not see the slightest trace of fungus. —Dr. Howard then read a paper entitled "Xotes on a Myin; Trip to Russia," exhibiting many photographs i<> illustrat- various places visited, and commenting on the collection- insects seen. 192 PROCEEDINGS ENTOMOLOGICAL SOCIETY NOTES ON A FLYING TRIP TO RUSSIA. BY L. O. HOWARD. In the course of one of my European trips, taken for the purpose of perfecting the organization for the introduction of the European parasites of the gipsy and brown-tail moths, I had occasion to visit St. Petersburg, Moscow, and Warsaw, in the latter part of May last. Only four days were spent in Russia, and most of the time was devoted to the purpose of the visit, but some very brief notes were taken about Russian entomologists and Russian collections, which may be of interest to the Entomological Society of Washington. The meeting rooms of the Entomological Society of St. Petersburg are in the building of the Ministry of Agriculture. Formerly they were on the third floor, but have recently been moved to the first floor. The society is now housed in one large room. The furniture is fine and old, and there is a long table about which the members sit at the meetings. There are closed cabinets and books around the walls of the room. The collections are not extensive, and do not seem to have been well cared for. At the time of my visit things were very much in confusion and certain cabinets had not been moved down from the third floor. With the help of Mr. George Jacobsen and an assistant I searched everywhere in the new room and the old for the collection of insects made by Nietner in Ceylon and sent to Motschulsky for determination, but without success. Mr. Jacobsen assured me that he had seen the collection in the cabinet of the society, and that when matters were more settled he would find it and would loan me any of the specimens I might desire to see. On the occasion of my first visit to the Ministry of Agri- culture I had the pleasure of meeting for the first time Pr.ofes- sorsor Porchinsky, a tall, fine looking gentleman with extremely cordial manners. He was on the point of starting on an expe- dition, and his rooms were in great confusion owing to his ex- pected prolonged absecne. He is very familiar with the work of the American entomologists, and especially of the economic entomologists. The building of the St. Petersburg Academy of Science-- is a very large but very plain stone building, yellow-washed. The main exhibit collections are on the second and third floors in one enormous gallery. The zoological collection^ arc very fine — many beautifully mounted groups illustrative of the life history and habits of very many Russian-Siberian mammal- OF WASHINGTON, VOLUME XI, 1909. 193 and birds. Possibly the most striking exhibit is tin- famous hairy mammoth of the Lena. On the ground floor the inter- minable dark corridors are lined with cases of alcoholic spec- imens of fishes, reptiles, and marine invertebrates. The labor- atory rooms are apparently all on the ground floor. Tilt- entomological department is large, and consists of a series of communicating rooms with windows on one side. The cases are arranged along the unlighted walls and in transverse stacks, the passages bet\veen the cases being narrow Inn abun- dantly lighted by hanging electric bulbs, which can be turned on whenever it is necessary to examine cases or labels. Thr insect exhibit is in the gallery above the main zoological depart- ment. It is contained in upright glass cases, each prctectcl from light by a curtain drawn by a spring which closes a ^piral on a rod above. The personnel of the entomological department is very- interesting. The Director of the Zoological Department is an entomologist, Professor Xassunow. He is a tall, distin- guished man, of apparently sixty ; speaks no English. He is an authority on the Cocci che, and presented me with his papers. The Academy apparently has no collection of (.'occid;e, and Professor Nassunow keeps his own collection at his home, so that I did not see it. The well-known orthopterist Adclung was -not at the museum at the time of my visit, although con- nected with the department. George Jacobsen in Coleoptera, Kusnezov in Lepidoptera.

In the Hymenoptera they have all of the F. Morawitz collection, as well as the collection of Jaroschevsky, and in part the collections of Kokujev, R. du Huysson's Vespirlse, Ruzsky's Formicidae. In Hemiptera they have parts of the collections of B. Jakovlev, Melichar, O. Renter, and Oshanin. In Orthoptera they have part of the Saussure collection, part of the Brunner von Wattenwyl col- lection, and also the collections of Eversmann, Adelung, and part of the Zubovsky collection. In Coleoptera they have the Menetries collection, part of the Motschulsky collection, and part of the Semenov. They have also the collections of A. and F. Morawitz, of Solsky, Blessig, Rybanov, and George Jacobsen. As above stated they have the material from very many expeditions — from all the polar expeditions, from Schmidt (1862) down to Toll (1902-5). It is very rich in central Asiatic collections. It has all the material from the I Yzewabsky, Kozloff, Roboroffski, and Berezofski expeditions, the latter to Mongolia, and of the Potanin.and Pebzoff expe- ditions to Thibet ; also many others. The determined material of the expeditions of Schrank, Mark, Radte, and Middendorf to Turkestan are also there. I was informed that Professor Menzbier, at the University of Moscow, has some of Motschulsky's types, and that Charles < )l>erthiir, at Rennes, possesses more. Also that there are some in the Moscow Society of Natural History ; others in the Mannerheim collections in the university at Helsingfors. The collections of the Academy are all admirably cared for. and form a marked contrast to the condition of the cabinets at the St. Petersburg Entomological Society. At Moscow I visited the zoological museum of the univer- sity, but was not able to get to the collection of the society.

Related to Ocvusa Kr., but with entirely different labrum, mandibles, and ligula: possibly related also to Tricolpochila r.rnb. Winged. Labrum strongly transverse, apparently trilohed and on the middle lobe with 3 equidistant teeth. Mandibles extremely long, thin, curved. acutely pointed, sickle-shaped, both with an oblique, sharp, rather long tooth behind the middle, before the tooth crenulated. Inner lobe of the maxillas from apex to middle with comb-like teeth, in basal two-thirds with finer spines: outer lobe at apex membranous, with fine hair-like spines. Maxillary palpi rather long, four-jointed, joint 2 shorter than 3: 3 club-shaped: 4 small, aciculate. Mentum transverse, slightly emarginate. Ligula very short, one-half as long as the first joint of the labial palpi, split in two lobes to the base. Labial palpi moderate: joint 1 the longest and the thickest; 2 very -.hurt, about one-third as long as 1 : 3 about twice as long as 2.

It was with some hesitation that I prepared the above gen- eric description, as T thought that such a conspicuous, rather 198 PROCEEDINGS ENTOMOLOGICAL SOCIETY common species might have been discovered and made known long ago; but I have failed to find any genus in the literature at my disposal which would even approach this most remark- able member of the Aleocharime subfamily. Il is barea possible that the genus has been placed by a previo-.is author in some other staphylinid subfamily: if so, it cer'ainlv ought to be transferred to the Aleocharinse, as the position of the antennae and the form of the anterior and posterior coxa? do not admit of any other interpretation. The size and frrm of the mandiblrs a'rl the c^traor- dinary, toothed labium ( provided I interpreted correctly my dissected specimen) are, to my knowledge, unique in the subfamily. Gnathusa eva, spec. nov. Robust, stout, subparallel, moderately shining, with somewhat coarse, sparse pubescence. Head black ; prothorax scarcely a little paler, elytra piceous black, sometimes almost black. Abdomen black. Anten- na? entirely reddish brown. Femora piceous ; tibia? and tarsi reddish brown. Antennae rather short, scarcely as long as head and pro- thorax together, strongly incrassate toward apex ; joint 1 moderately elongate ; 2 much longer than 3 ; 4 square ; 5 and 6 about equal ; 7-10 gradually strongly wider, 10 more than twice as wide as long; 11 oval, blunt, scarcely as long as 9 and 10 together.

Elytra scarcely one-fourth longer and a little wider than the pro- thorax, together wider than long, outer hind angles moderately emar- ginate ; rather sparsely, very coarsely, granulately punctate. Abdomen broad, widest in the middle, narrowed in front and behind : in the middle as wide as the elytra ; segments 3-5 strongly transversely impressed at base: rather sparsely, very coarsely punctate, behind a little more sparsely and more finely so. There arc no sexual char- acters on the elytra nor on the abdomen. Length 3 mm. Type — No. 10592, my collection. Fifty specimens from Tahoe City and Tallac, California, sifted under decaying vegetable matter: taken also in evening flight. I have also specimens in my collection taken in the San Bernardino Mountains at Sugar Pine. Summer dale, and Mohawk, all in California. The mouthparts are those of other species of the genus HoUtocIiara. The species is unique in our fauna on accoun! its uniform color and the lack of sexual characters of the male. I found my specimens under deep layers of decaying leave- in the coniferous forests around Lake Tahoe. They were feeding probably on minute fungi. Although winged, they slinw an unmistakable tendency toward becoming apter in the course of time. The rather abbreviated elytra, the dilated abdomen, and the pale uniform color may be men- tioned as proof of this tendency. 200 PROCEEDINGS ENTOMOLOGICAL SOCIETY DESCRIPTION OF THE LARVA OF EUSTROTIA CADUCA GROTE. [Lepidoptera, Noctuidae.] BY HARRISON G. DYAR. Larvae found feeding upon the leaves of the yellow water- lily at Hyattsville, Maryland, proved to be of this species. The larvae are not aquatic, except that they have to swim from the leaves to ground when fully grown and seeking a place for pupation. The eggs are of the shape of one-third of a sphere, the base broadly flat, low-domed, with 40 vertical ridges at the margin, diminishing irregularly to the vertex ; cross-striae faint and fine. Pale green. Diameter 0.7 mm. Laid usually singly on the back of a leaf. The young larvae are slender, translucent pale green without markings, the spiracles white, that of joint 12 large. Stages ir to vi were under observation upon the plants at the time of finding. The mature larva has the head flat before, held flat, the vertex not within joint 2, slightly bilobed, rounded, pale green, translucent, with a few pale red-brown subangular spots. Body subcylindrical, flattened ; the thoracic feet small, the abdominal ones with long plantae, the pair on joint 13 spread- ing. Smooth, translucent pale green ; dorsal, subdorsal and stigmatal whitish green lines running to the eye, with a series of pale red-brown angular dots below the subdorsal line, one on each segment posteriorly. Under a lens the dorsal and subdorsal lines remain, the stigmatal disappears, and only four linear waved lines are seen, two in the lateral space, one stig- matal and one subventral, which are so fine as to be not obvious to the eye. Tubercles and setae minute. Spiracles black- edged. Antennae large, well jointed. The larvae turned red at maturity and entered earth, spinning a slight web. OF WASHINGTON, VOLUME XI, 1909 201 A NEW TORTRICID OF ECONOMIC IMPORTANCE IN THE HAWAIIAN ISLANDS. [Lepidoptera, Tortricifht. ] BY AUGUST BUSCK. Amorbia emigratella,new species. Male and female. Female. — Basal joint of labial palpi short, ochreous; second joint long, porrected, rust-red, with a violaceous sheen on the tip ; terminal joint short, reddish brown, shaded with black. Face behind the palpi short-scaled, whitish; head reddish brown, mixed with ochreous and uith a short pointed frontal tuft. Antennae reddish brown, simple. Thorax and patagia uniformly dark brown. Fore wings with base .of costa strongly arched; costal and dorsal edges nearly parallel; apex squarely pointed; termen slightly sinuate below apex, thence evenly rounded; ochreous brown, shading into light ochreous on the terminal third: the edge between two colors is not sharply drawr. but the limits are still quite distinct, the lighter color occupying the an a below a straight line from basal fourth of the dorsal edge to apex. From just before the middle of costa runs an indistinct, dark bluish- gray band obliquely outward towards tornus, but fades out in the ochreous part of the wing and is even interrupted in the brown costal part : parallel with this is another similarly colored, but less distinct . streak at apical third, also disappearing in the light portion of tin- wing. On the dorsal edge at basal fourth and at the middle are two short dark gray streaks, parallel with the costal streaks. The entire wing is finely mottled with a close transverse apparently darker striation, which is produced by transverse rows of slightly elevated scales. These markings are of varying intensity in different specimens. some showing hardly any trace of the darker cross-bands and having the ground-color lighter and nearly unmottled except for the tine transverse striation caused by the slightly raised rows of scales. Hindwings light straw-yellow, with the apex mottled with dark hnmn and black and with the costal cilia absent and abruptly beginning again just before the tip of the wing. Cilia straw-white. Underside of the forewings reddish ochreous, with a blackish terminal line before the cilia. Abdomen light yellow. Legs straw-yellow : tin- anterior and middle legs shaded with reddish brown exteriorly and with the tarsi faintly annulated. Alar expanse, 27-29 mm. Male. — Of considerably smaller size and of a general lighter color Forewings nearly uniformly light ochreous without the darker ba-.,l and costal shade. The first costal dark streak is represented by a dark bluish brown triangular spot, terminating in a nearly black dot; 202 PROCEEDINGS ENTOMOLOGICAL SOCIETY the second costal streak is replaced by a faint, curved, dark line, emitted from a small bluish brown costal spot. The transverse striation caused by the rows of slightly raised scales is apparent. The antennae are pectinated. While the two males from Hawaii before me do not exhibit much variation, a similar range of variation as is found in the females may be expected in the males. Alar expanse, 20-23 mm. Habitat — Tantalus and Makiki, Oahu, Hawiian Islands, Otto H. Swezey, collector. Type— No. '12777, U. S. National Museum. The types of this very distinct species were bred by Mr. Otto H. Swezey, assistant entomologist of the Hawaiian Sugar Planters' Association, who writes as follows, under date of October 26, 1909 : This tortricid is quite a pest in the Hawaiian Islands. The larva? are leaf-rollers on many kinds of plants, shrubs, and fruit-trees, often so numerous as to defoliate the trees and sometimes attacking the fruit as well. It is an introduced species here which has been present for several years. No one here knows where it came from, nor has anyone learned its identity. The species has long been known to the writer from Mexico and has undoubtedly been introduced from that country to Hawaii within comparatively recent years. In the National Museum are specimens from Jalapa, Santa Rosa, Orizaba, Vera Cruz (Wm. Schaus coll.), and Mexico City (R. Miiller coll.), Mexico, and from Costa Rica (Wm. Schaus). The species comes nearest the darker and larger North American species, A. cuneana Walsingham. The genus, which is characteristic of America, has veins 7 and 8 in the forewings stalked in the female, coincident in the male, but is, aside from this secondary sexual character, amply defined by characters common in both sexes, the ven- ation and form of the hindwings, and the raised scales of the forewings.

Tongue ochre-yellow. An- tennae blackish, basally with white annulations. Head white. Thorax white with posterior tip black. Fore wings pure white with a costal longitudinal streak from base to apex dark slate-colored ; at the extreme- base of the dorsal edge is a deep black round dot and on the wing are six similar black round dots, placed in pairs in two longitudinal rows of three dots each: the first pair at basal fourth, with the upper dot slightly nearer the base of the wing than the lower dot ; one pair on the middle of the cell and one pair just beyond the end of the cell: in both these latter pairs the upper dot is placed obliquely to and further out than the lower. Along the terminal edge is a row of six black- marginal dots. Cilia white. Hindwings light slate-colored with white cilia and in the male with a strong yellow hair pencil at the base of the costa. Abdomen dark fuscous with second joint above and terminal joint ocher-yellow. Legs dark slate-colored with yellow tarsal annu- lations. Alar expanse, 21-22 mm.

A clear-cut species, nearest in color and size to the Euro- pean Ethmia sexpimctella but with the six spots placed dif- ferently and further distinguished by the male costal tuft. In the American series it comes next to Ethmia lia^cucUa Chambers. It gives me pleasure to name this pretty species in honor of the collector, Mr. R. Miiller, who has added very many Mexican Lepidoptera to our collections. Stenoma loxotoma, new species. Labial palpi long, evenly covered, reaching above the vertex: second joint thickened with appressed scales, slightly ruffled anteriorly to- wards apex; ocher-yellow at base, blackish above, whitish gray at the tip; terminal joint smooth pointed, whitish gray shaded to blackis'i fuscous anteriorly. Antenna?, male, shortly ciliated (1) gray with in- distinct darker annulations; basal joint thickened with scales. Face whitish. Top of head tufted, the long scales from each side meeting in the middle; whitish gray on the sides, darker gray at tip of tuft. OF WASHINGTON, VOLUME XI, 1909. 213 Thorax dark gray with a long slender appressed tuft of black hairlikt- scales reaching back over the first abdominal segment. Forewings with costa straight to apical third, there sharply deflexed, apex bluntly pointed, termen rounded, dorsal edge straight; color brownish gra\ with narrow ochreous edges and with three transverse, oblique, nearly parallel, narrow lines ; the first from basal fourth of costa somewhat undulated to apical third of dorsal edge; the second also somewhat curved from about the middle of costa to just above the anal angle and the third, which is nearly straight from just before the deflexion of the costal edge to the middle of termen. Cilia short, dark fuscous. Hind wings over 1, triangular with rounded apex and anal angle bright ochre- yellow.' Underside of all wings bright ochre-yellow. Legs ochre- yellow : first pair with the anterior side of the tarsi gray and heavily -caled as in some noctuids ; posterior tibiae with long smoothly ap- pressed hairs above ; the first tarsal joints similarly thickened with shorter hair. Abdomen ochre-yellow with rich chestnut-brown liar- above, one on each joint. Alar expanse, 43-50 mm. Habitat— Orizaba., Mexico, June (R. Miiller, coll.); Yera Cruz, Mexico (H. Schwarz, coll.). Trpe—No. 12809, U. S. National Museum. Cotype in Museum Walsing'ham. This species would, on account of the striking- wing" form and the peculiarly thickened front tarsi, fall in Zeller's genus l.oxotoma, which I, however, am unable to consider a g-ood g-enus. The family Stenomidse, which is a primitive family from which the family Oecophoridae has probably developed, exhibits a very wide range of specific specialization, but has differentiated itself into very few tenable genera. The trans- ition of the various forms of the wing's and of the numerous secondary sexual characters, tufts and fringes, exhibited in this family, is so gradual as to defy generic division, while the venation is remarkably uniform throughout the family. It seems at the first study impossible to place a species like the present or the similarly shaped type of the genus Lo.votoum (.elegans Zeller) in tte same genns with the superficially very different typical Stcnoina species; but if the recogni/.cd generic characters are compared one by one, they will be found to be identical and the present Species is, for example, undoubtedly quite as close to Sleinnna Iri^lri^n/n Zeller as to J.o.\-otoi>in /t^a//s Zeller, though the former could not be placed in Zel- ler's genus Loxoioma. 214 PROC. ENT. SOC. WASH., VOL. XI, 1909. A NEW SPECIES OF ACROBASIS. [Lepidoptera, Pyralidse.] BY HARRISON G. DYAR. \ Acrobasis feltella, new species. Fore wing of male with a small patch of black scales beneath subcostally. Wings dark gray, the inner band beyond the subbasal patch of raised scales very broad, creamy white, shading to orange below, especially wide in its lower part. In the male the basal space and all of the thorax are white ; in 'the female, these parts are gray. Discal dots joined. Outer line wavy-crenulate, defined by an out- ward creamy shade. Hind wing light at the base in the male, entirely fuscous in the female. Expanse, 14-17 mm. One male, one female, Warner, New York, July 7, 190(J (New York State collection), sent for identification by Dri E. P. Felt. Type— No. 12680, U. S. National Museum. The specimens were bred from larvae boring in the petioles of hickory. The species is similar to Acrobasis ncbulclla Riley. but differs by the conspicuous character of the inner pale band. MISPRINTS.
