WITH 7 PLAIN PLATES \) 74 ait “\\| genera are MOR widely distributed, occurring in all oie of the world, noe las. Europe, alle the known forms ea hon Africa and South America may almost be reckoned upon the fingers. Entomologists have long been acquainted with several members of this family, both Reaumur and Degeer having described the immature as well as the adult stages of several species. The earliest known forms were classified in the Linnean genus Tifula; to Bosc belongs the credit of having defined the first Mycetophilid genus, Cevoflatus, in 1792. Meigen was the first to publish extensively upon this family and his works form the foundation of all later work. But few monographs have appeared. The first, Observationes de speciebus nonulles generis Mycetophila vel novis, vel minus cognitis, by F. H. Stannius, was published in 1831. The most important and indeed the only comprehensive paper which forms the basis of all recent systematic work was written by J. Winnertz, published in 1863, and deals with the European fauna. The year following, Schiner in his Fauna Austriaca tabulated the Austrian genera and species. Of the more recent writers whose works are of special importance may be mentioned Dziedzicki, Lundstrém, Skuse and Marshall. Our knowledge of the early stages of these flies is by no means extensive, although a number of isolated observations have been published. These were collected by Baron C. R. von Osten Sacken, and together with some researches of his own were published in 1864. They were reprinted in 1884 with a few additions; since then but little has been published upon the biology. Geological distribution. — In spite of the small size and fragile character of these insects they appear to have been preserved from mesozoic times. Brodie has described several species from the English Purbecks. Others have been described by Westwood, Giebel, Scudder and Cockerell. The 2 DIPTERA family is very abundant in amber; Loew, and quite recently Meunier, have described numerous genera and species from the Baltic amber. The fossil genera thus far described do not differ strikingly from some of the recent forms, and indeed the differences in some cases are so slight that it is difficult to separate them. Several genera, heretofore known only as fossils, have been discovered by the writer among living forms, and for this as well as for other reasons they have been considered in the tables which follow. Immature stages and habits. — The larval stage of the Mycetophilide (exclusive of the Sciaride) with but few exceptions is passed in mushrooms and decaying wood. The eggs, white oval bodies, are laid in the soft wood or between the gills of a mushroom and develop very rapidly. The larve differ somewhat in structure though superficially possessing a very great similarity. They ‘are twelve segmented, footless, more or less cylindrical, slightly tapering, smooth, soft, whitish in color and with a small strongly chitinized head, which is usually brown or black. The antenne are always very minute, almost rudimentary. The mouth parts consist of a feshy labrum, with a chitinized frame; flat lamelliform mandibles, indented or serrate on the inner side; maxille with inner and outer lobes, the former usually serrate, and a small chitinized labium. The body of the larva is without hair or bristles except that in some genera there are one or two transverse rows of simple or bifid ambulacral setulae on the margin of each abdominal segment on the ventral side. There are eight pairs of spiracles, one on the thorax and seven on the first seven abdominal segments, the last two segments having none. These spiracles are protected by small, chitinized conical projections. The pupz are extricated, that is, not encased in the contracted skin of the larva. The legs are applied to the breast and venter, the antenne are bent around the eyes, and extend between the wings and legs. The prothoracic spiracle is placed a little above the root of the wing and immediately behind the antenna. The abdominal spiracles are distinct on both sides of the abdomen. The pupa is smooth, white in color and usually encased in a delicate cocoon. The pupe of those forms whose larve live in mushrooms are usually found in the soil and among the decaying parts of the plant. The larval and usually the pupal life also is of short duration. The time which elapses from the egg to the adult stage may not exceed two weeks in midsummer. For expediency’s sake, and also in deference to the opinion of many dipterologists the Sciaridz are not included with the Mycetophilide although it must be confessed they are no more remote from some genera of the subfamily Mycetophiline than the genera Diadocidia and Bolitophila, and certainly as near as the genera Pachyneuva and Thivas which I have included. I have also included several genera in my tables which probably belong with the Sciaridze but because of their transitional characters might be wholly overlooked were they omitted. Hitherto the wing venation has been most used for generic cha- racters but more attention must in the future be paid to seta arrangement, claws, palpi, ocelli. antennz and particularly to the male genitalia. With the discovery of new species from the unexplored regions of the world some transitional forms will doubtless be found and some of the present genera will then have to be combined. In the present paper the fossil genera are included though their consideration makes the definition of recent genera more difficult and restricted. The only family with which the Mycetophilide as here considered may be confused is the Scia- ride. It differs however in wing venation; the R-M crossvein is parallel to the long axis of the wing and forms apparently the base of a longitudinal vein; the cubitus (except in some fossil forms) has a very short petiole, the subcostal vein, though usually rather long, ends free, and the media has an elongate but very slender petiole (Pl. 6, Fig. 28, 29). The head also is placed at a higher level relatively to the thorax, the thorax is less arched, and the cox are not so conspicuously elongate. Family characters of the adult. — The head is narrower than the thorax, spherical or elon- PAM. MYCE TOPHIEIDIA: 3 gate, flattened in front or somewhat rounded, placed low relatively to the thorax, front in both sexes broad; either nearly bare or microscopic pilose. The proboscis is usually short and retracted, in a few genera much elongated. The palpi are three or four jointed, usually incurved, the first joint always very short. The eyes are round or oval in outline, often notched out around the base of the antenne, short pilose. There are usually two or three ocelli, rarely are they absent. The middle ocellus, when present, is always on the center line; the laterals may be closely contiguous to the eve margin or widely remote from it. When three ocelli are present they may be placed in the form of a triangle on the front or arranged in a curved line. The middle ocellus is frequently very small. The antenne are 2-4 Io to 2 + 15 jointed, the basal joints differentiated from the others, the first two cylindrical or cupuliform, the flagellar joints usually cylindrical, though sometimes moniliform, and very short pilose. The thorax is oval, more or less highly arched, without transverse suture, the metanotum highly arched, sometimes almost vertical, the mesonotum and pleura pilose and frequently more or less setose; the small scutellum often with several long sete. The abdomen is six to nine segmented, cylindrical, conical, or oval and laterally compressed, constricted at the base, the male with rather complex caudal appendages (Pl. 7, Fig. I-20), the female with a short oviduct with terminal lamellae; abdominal hairs and sete usually quite short and inconspicuous. The coxe are very strong and much elongated except in two or three genera; the femora more or less thickened, laterally compressed, often setose; the tibiz usually slender, the fore pair with one long and one short terminal spur, rarely wanting; the middle and hind pairs usually with two spurs each and with from one to four longitudinal rows of setae outwardly and sometimes with a row on the flexor surface; seldom are the sete wanting; the tarsi frequently with ciliated planta, tarsal claws with teeth. The wings are usually oval, more or less constricted at the base, hairy or more frequently micros- copically setulose, and without the cell first M, (discal cell). While the venation is quite varied it may be resolved into four principal types (shown in PI. 2, Fig. 1-4) from which all the others may readily be derived. The most generalized (hypothetical) form is shown in PI. 2, Fig. |, differing from Palacoplatyura (P|. 3, Fig. 7) which is represented by both fossil and recent forms in no wise. Only Pachyneura and Thiras (fossil) have a greater number of veins and these two genera are of doubtful relationship. Below is given the Comstock- Needham terminology of wing venation which is used in the following text, together with the equivalent terms of the Schinerian system. Costag (© je —"Gostar, Cy) —- Sl bcosta:. Seheteote Ke) Se, = Subcostal crossvein. R, = First longitudinal vein. Radius Redmibecetona(es) { Ras = els branch of pied ot iy. R,;; = Posterior branch of the third longitudinal vein. Media. . . . (M) = Fourth longitudinal vein. Cubitus . . . (Cu) = Fifth longitudinal vein. Anal veins. . . (A) = Anal veinand axillary vein. Crossveins. Subcostal (see above, Scz) = Subcostal. Radio-Medial (R-M). . == Anterior crossvein. Medio-cubital (M-Cu) . = Posterior crossvein, In this system the cells are given the names of the section of the vein immediately in front of it; thus the cell behind the costa is called the costal cell (or C), the cell behind the basal section of the 4 DIPTERA radius is called R, that behind R, is called cell R,, etc. In the case of the Sciophilinz where R,.1; is transverse in position, the small cell is called R, and the outer cell is R13, for were the vein R,,; normal in position, i. e. longitudinal, this would be the logical nomenclature. The whole of the posterior part of the radius consisting of R,;3 and R,1;5 is called the radial sector (Rs). Some writers (Winnertz among others) have erroneously considered the base of the sector as a crossvein, while they called the true crossvein the base of the third longitudinal vein (R,+5). Phylogeny. — The Mycetophilide may be considered as having descended from an ancestral form which possessed elongate antenne of seventeen segments, coxe of moderate length and wings with a venation resembling that shown in Pl. 2, Fig. 1, but with a four branched radius as in Pachyneuva (Pl. 3, Fig. 4). From this form arose the Pachyneurine on the one hand and a form having the wing venation shown in Pl. 2, Fig. | on the other. From the latter we may imagine arose all the other subfamilies; the Bolitophiline (Mycetophaetus, Hesperinus, Bolitophila); the Mycetobiine (PI. 2, Fig. 2), in which the base of the media is lost; the Diadocidiiz in which one branch of the radius has disap- peared; the Ceroplatine (through Hesperodes and Apemon) and Macrocerinz, where a coalescence of a section of media and cubitus has taken place; the Sciophiline (Pl. 2, Fig. 3), in which the M-Cu crossvein is absent, and finally the Mycetophilinae (PI. 2, Fig. 4) in which both the M-Cu crossvein and the vein R,;; are lost either by atrophy or by coalescence. In the process of evolution the venation becomes simplified, the antenne are shortened, the coxe lengthen, and finally in the most recent genera the tibial setae are greatly developed. Nomenclature. — It was originally the intention to make no changes in the existing nomen- clature, but this was found to be impracticable. As the work progessed changes were introduced for the sake of consistency until finally it is believed the nomenclature is brought into conformity with the rules of the International code. This has occasioned a regrettable though unavoidable transposition of names due mainly to the recognition of some of the genera of Rondani. lhe earliest names of Meigen: Zelmiva, Polyxena, Euphrosyne and Fungivorva (published in 1800), have not been given precedent. The first two are briefly described but no type is mentioned, the synonymy of the third is in doubt, and the fourth seems to have been used at a still earlier date, but this last point I have been unable to verify. Besides the substitutions made for names which have been used before (Deiedsickia and Meunieria), and the introduction of one new one, Afemon, the following transpositions may be noted : Lasiosoma (Winnertz) replaced by Sciophila; Empheria and Scwophila (in sensu Winnertz) by Mycomya; Anaclima by Neuratelia ; Glaphyroptera by Leta; and Leta (in sensu Winnertz) by Rondaniella. Empheria and Sciophila (Winnertz) have been combined under Mycomya, and Allodia and Brachycampta under Allodia because the characters given for their distinction are inadequate. If these genera must be preserved their separation must be made along entirely different lines. Mycetomyza, Rondani (= Mycosia) is probably a synonym of Sciara. Diagnoses of the following new species are published in foot notes under their respective genera : Palaeoplatyura Aldrichit, Allocotocera flavescens, Anatella silvestris, Cordyla volucris, and Opistholoba ocellata.

As it is represented by only the wing its position in this subfamily is somewhat doubtful. The wing venation differs from all other members of the family in having a four branched radius, as in Pachyneuva, but having a simple media. The venation resembles somewhat that of Mycefobia, in having a closed basal cell. The subcostal vein extends beyond the middle if the wing, its posterior branch is wanting, R, is distinct from R; ; the media is simple, the two crossveins are about equidistant from the base of the wing; the anal veins well developed (PI. 3, Fig. 5).

MACROCERINAZ& Macrocerinae. Winnertz, Verh. Zool.-Bot. Ges. Wien. Vol. 13, p. 675 (1863). Characters, — This subfamily difters from Ceroflatine primarily in having extremely long antenne, often much longer than the body. In the wing venation there is no great difference; R,1; al- ways ends in the costa. Sc, is present, and the anal vein is more or less sinuous and ends in the margin 28 DIPTERA of the wing. The fossil genus Sama, Giebel, which was figured by Brodie is too poorly preserved to place with certainty. According to Scudder the fossil genus Macroura, Berendt, may be the same as Macrocera, Macrourva only being a misprint. Berendt mentions no species. There is but one living genus in this subfamily. 1. GENUS MACROCERA, MEIGEN ? Euphrosyne. Meigen, Nouv. Classif. des Mouches a deux ailes, p. 16 (1800). (Doubtful type). Macrecera.

Characters. — This Jurassic genus, because of its extremely long antennz, may be considered as belonging to the Macrocerinae, if indeed it isa member of the Mycetophilidae at all. Of the wing venation nothing can be made out, hence the relationship is very doubtful.

Scudder, Geol. Mag. Vol. 4, p. 2 (121) (1895). Characters. — A fossil genus from the Miocene. The costa extends to the end of R,; the subcosta impinges on R, just beyond the origin of the radial sector, which arises at about two-fifths the distance from the base of the wing to the apex; cell R,;5 extends back to the basal cell R itself and the cubitus forks far proximad of the R-M crossvein. In the original description of the author it is stated that the « brachial crossvein » is at the middle of the wing meaning doubtless vein R,13 which appears to be shown in the author’s figure (Pl. 6, Fig. 5) though but faintly and indistinctly (compare PI. 8, Fig. 28). The hind thighs are stout, longer than the thorax; the hind tibia, which are twice as stout at the apex as at the base, are armed with a pair of stout apical spines half as long as themselves, while the hind tarsi are half as long again as the tibie.

Vol. 1, p. 245 (30) (1818); Rondani (nec Winnertz), Dipt. Ital. Pro- dromus, Vol. 1, p. 194 (1856). Lasiosoma. Winnertz, Verh. Zool.-bot. Ges. Wien, Vol. 13, p. 748 (1863). Characters, — The name Sciophila is used here in the sense of Rondani (1856) and includes all the species classified by Winnertz (1863) in his genus Lasiosoma, the latter thus becoming a synonym of the former. The species which Winnertz placed in Sciophila are transferred to Mycomya, Rondani, where they rightfully belong. Head small, spherical, flattened in front, placed low upon the thorax; eyes oval, slightly emar- ginate at the base of the antennz, almost reniform; ocelli three in number, arranged in a flattened triangle upon the broad front or more rarely upon the vertex, the middle one only slightly smaller than the laterals; palpi incurved, four jointed, the first joint very small, the second and third subequal, tho last longer than the others taken together; antenne, projecting forward, arcuated, somewhat compressed, 2+14 jointed, the two basal joints cupuliform, hairy. Thorax oval, highly arched; mesonotum long and thickly haired, not setose; scutellum very small; halteres with short petiole and elongate knob. Abdomen seven segmented, cylindrical, somewhat constricted at the base, hairy, in the male with blunt extremity and small forceps (PI. 7, Fig. 2). Legs moderately long; the tarsi of the fore legs double the length or rarely more than double the length of the tibia. The tibia with spurs and with lateral sete, the fore pair with one or two, the middle pair with three and the hind pair with four rows, the inner rows with only few and weak sete. Wings elongate oval, with rounded base, longer than the abdomen, hairy, hairs sometimes visible with the naked eye. The costa produced far beyond the tip of R45, but not reaching the tip of the wing; the subcosta usually extends distad of the small cell and ends in the costa; the cell R, very small and usually rectangular; the media forks at or but very little distad of the R-M crossvein; the cubitus forks noticeably distad of the fork of the media; the anal vein incom- plete, ending far from the margin of the wing (Pl. 3, Fig. 29). These flies are prevalent in Spring and Fall; the larve live in rotten wood and in fungi. Io. Ii. Te T4. . cinctum, Winnertz, Verh. Zool.-bot. Ges. Wien, Vol. . curvipetiolata, Meunier (fossil), Mon.

GENUS PALZOEMPALIA, MEUNIER Palzeoempalia. Meunier, Bull. Soc. Ent. Fr. p. 218 (1897). Characters. — This genus, erected to contain fossil forms, will, as here defined, include also one recent species. The principal difference between this and the foregoing genus is that in this the cubitus forks under or proximad of the R-M crossvein. The small cell R, also usually appears to be rather longer here than in Empalia. In other respects there appears to be no difference (Pl. 4, Fig. 5). FAM.

GENUS DIOMONUS, WALKER Diomonus. Walker, List Dipt. Brit. Mus. Vol. 1, p. 87 (1848). Characters. — This genus resembles Mycomya in wing venation, but differs in having three ocelli widely separated, the middle one but little smaller than the laterals (PI, |, Fig. 20). In the species with which I am familiar the basal joint of the antenna is densely pilose on the underside, the flagellar joints are somewhat flattened, especially toward the apex of the antenna (PI. I, Fig. 14), and the thorax is pilose rather than setose. The costa ends at or but very slightly beyond the tip of R,1; close to the tip of the wing; the small cell R, is less than twice as long as wide, the petiole of the media is much longer than the R-M crossvein; the cubitus forks far proximad of the fork of media; the setule of the wing surface are longer and more dense than in Mycomya, and the wing has two dark spots upon it (Pl. 4, Fig. 8). The legs are very long, the middle or hind femur of the male bears a blunt spine on the underside, and the male genitalia usually have two slender curved filaments (aT Fig. 4). The known species are 6-10 mm. in length. In other respects like Wycomya. Type species : D. nebulosus, Walker. Geographical distribution of species : \ 1. D. bifasciatus, Say, Long’s Exp.

GENUS SCIOBIA, LOEW Sciobia. Loew, Ueber den Bernstein und die Bernstein Fauna (1850). Characters. — A fossil genus, probably identical with Mycomya. Meunier mentioned it in a note in Bull. Soc. Ent. Fr. p. CX (1894), but does not consider it in his Mon. des Mycetoph. etc. de Vambre de la Baltique (1904). Geographical distribution of species. — The following three species were very briefly described by Loew, from the Prussian amber : 1. S. pendicularis, Loew, Ueber den Bernstein und die Bernstein Fauna, Prussian amber. ao4 (1000). \ 2. S. quadrangularis, Loew, ibidem, p. 34 (1850). Prussian amber. 3. S. spinosa, Loew, ibidem, p. 34 (1850). Prussian amber. 8. SUBFAM. MYCETOPHILINA Mycetophilinze. Winnertz, Verh. Zool.-bot. Ges. Wien, Vol. 13, p. 659 (1863). Characters, — The subfamily is distinguished from the others by the absence of the M-Cu crossvein and by its simple, 1. e. unbranched, radial sector. It fails naturally into two groups; in the first the lateral ocelli are separated from each other and also remote from the eye margin, while the middle one is more or less conspicuous, and associated with this character in most of the genera is the presence of an elongate subcostal vein; in the second group the lateral ocelli are contiguous or nearly contiguous to the eye margin, the middle one usually very small or entirely wanting, and the subcostal vein is frequently very short or rudimentary. The setule on the wings, particularly in the members of the second group, are very minute and arranged quite regularly in longitudinal rows, while in the other subfamilies the arrangement is much less regular. The second group may again be subdivided into two 52 DIPTERA series in the first of which the tibial sete are short and slender, usually scarsely longer than the diameter of the tibia, and the larve have no ambulacral setulae; while in the second series the tibial sete are very strong and conspicous and the larve as far as known have one or two transverse rows of ambulacral setule on the ventral side of most of the body segments.

Eyes large, approximate beneath; ocelli three, arranged in a small triangle on the vertex, the anterior one very small; proboscis very long and slender, rather more than one-half the length of the entire body; palpi apparently wanting; antenne porrected, cylindrical, short, 24-14 jointed; flagellar joints longer than broad, progressively diminishing in thickness, with a microscopic pubescence. Thorax _ short, ovate, very gibbose; scutellum small; metanotum large, acclivous. Abdomen slender, somewhat compressed from the sides, narrowed at the base and extremity, seven segmented; terminal lamelle of the ovipositor elongate elliptical. Legs long and slender, coxa somewhat elongate, as in Sciava, fore and intermediate femora slender, the hind pair dilated, a little longer than the other pairs; fore and inter- mediate tibiz and tarsi very slender; hind tibiz incrassated towards the apex, nearly twice the length of the fore pair; hind tarsi thicker than those on the other legs. Fore tibiae with one, intermediate with two very small spurs; hind pair with two unequal spurs; no lateral spines. Wings shorter than the abdomen, moderately broad, rounded off at the base, incumbent in repose; microscopically pubescent. Costal vein extending much beyond the tip of the radial sector, but not reaching the apex of the wing; subcostal vein incomplete, very short, close to R, ; R, short, reaching the costa considerably before the middle of the wing; the radial sector arising apparently at the base of the wing, tolerably straight, terminating in the costa opposite the tip of the posterior branch of the media; media incomplete, the petiole and the base of the fork wanting; fork of the cubitus small, the anterior branch detached at the base; anal vein very rudimentary (PI, 1, Fig. 23; Pl. 4, Fig. 18). The insect reminds one more of the Sczavidae than the Mycetophilidae, especially in the situation of the head, size of the coxa, and length of R, ; while the characters of the proboscis and venation of the wings afford characters very distinctive from any hitherto described genus in either family.

GENUS RONDANIELLA, NOM. NOV Leia. Meigen (Winnertz), Verh. Zool.-bot. Ges. Wien, Vol. 13, p. 792 (1863). Characters, — Head oval, flattened in front, placed low upon the thorax; eyes oval; ocell1 three in number, arranged in a triangle upon the broad front or almost upon the vertex, the laterals larger than the middle one; palpi incurved, four jointed, the first joint small, the two following subequal, the fourth as long or longer than the others taken together; antenne projecting forward arcuate, 2-14 join- ted, the first and second joints cupuliform, the second with sete at the tip, the flagellar joints cylindrical, pubescent. Thorax oval, highly arched, the metathorax steep; scutellum small, nearly semicircular. Abdomen slender, six segmented, in the male nearly cylindrical, somewhat diminishing in size towards the apex, with small forceps; in the female somewhat depressed, with stout ovipositor ending in two small lamella. Legs strong, the femora, especially hind pair, flattened, the tibiae with spurs and with lateral sete. The fore tibiz have a row of sete on the outer side, also one seta on the inner side near the middle, another near the outer row, and a third at the apex near the spur; the hind tibize have three rows of strong sete outwardly, the middle tibiz each witha single long seta on the inner side somewhat beyond the middle. Wing longer than the abdomen, elongate oval, with rounded base, microscopic setulose. The subcostal vein ends at about one-third the length of the wing, its posterior branch (subcostal cross- vein) is wantin ;; the costa ends far beyond the tip of the radial sector, but does not reach the apex of the wing; the radial sector arises at the middle of the wing hence the basal cell R is about half the length of the wing; the base of the anterior branch of the media and also of the cubitus is wanting; the anal vein is incomplete (Pl. 4, Fig. 24). The name Leia was used by Rondani (1856) in the sense in which Winnertz (1863) and subsequent writers used Glaphyroptera and Neoglaphyroplera. Furthermore Leia fascipennis, which was designated as the type of the genus by Curtis, belongs to Leva in Rondani’s sense, hence this name must be transferred to its proper position and the Leva of Winnertz renamed.

Abdomen seven segmented, long and slender, cylindrical; in the male with a short forceps (Pl. 7, Fig. 8, 9), in the female with a very short ovipositor at the tip of which there are two small lamellae. Legs long and slender, the femora slender, slightly compressed, all tibiz with spurs and with weak lateral sete; fore metatarsus shorter than the corresponding tibia. Wing elongate oval, with somewhat rounded base, as long as or somewhat longer than the abdomen, microscopic setulose. Costa somewhat produced beyond the tip of the radial sector but not reaching the tip of the wing; subcostal vein ends in the costa before the middle of the wing length, and is connected with R, by Sc, (subcostal crossvein); media forks under or somewhat distad of the radial sector; cubitus forks under or proximad of the fork of the media; anal vein incomplete (Pl. 5, Fig. 8). The larve of these gnats have been reared from decaying wood and also from fungi; the adults are found in woods in all seasons except in mid winter, though more commonly in Spring and Fall. Euryceras, Marshall (Pl. 5, Fig. 9), and Palaeoboletina, Meunier (Pl. 5, Fig. 10), cannot well be separated from Boletina. The slight variations from the typical form which may appear in the wing venation are not sufficient to distinguish generically, when several North American species which form connecting links are taken into consideration.

MEUNIER Characters. — The antenne of the male longer than the head and thorax taken together, of the female somewhat shorter; basal joints differentiated, the first flagellar joint more than three times as long as wide, apical joint longer than the preapical. Wing elongate oval; costa produced beyond the tip of the radial sector; subcostal vein ends in the costa beyond the middle of the elongate basal cell R; base of the radial sector nearly transverse in position and less than one-third as long as the long R-M crossvein which is longitudinal in position and forms apparently the beginning of the sector; the petiole of the media about as long as the R-M crossvein; fork of the cubitus under or distad of the proximal end of the crossvein (PI. 5, Fig. I 1). 76 DIPTERA This fossil genus greatly resembles Leia (Glaphyvoptera Winnertz) but differs mainly in having the the costa prolonged beyond the tip of the radial sector, in the rather shorter basal cell R, and in the position of the fork of the cubitus distad of the proximal end of the R-M crossvein.

Vol. 1, p. 195 (6) (1856). Lejosoma. Rondani, Prodomus. Vol. 1, corrigenda (1856). Characters. — Head with elevated vertex, oval, flattened in front, placed low upon the thorax; eyes elongate oval, somewhat emarginate at the base of the anenne; ocelli three in number, placed in a curved line upon the broad front, the laterals large, rather close to the eye margin though not contiguous, the middle ocellus smaller; palpi large, incurved, four jointed, the first joint smallest, the fourth as long or longer than the preceding (PI. I, Fig. 24); antenne projecting forward, 2+-14 jointed, the two basal joints differentiated, setose at the apex, the flagellar joints cylindrical, somewhat compressed, short pilose. Thorax oval, highly arched; scutellum small, nearly semicircular in outline; metanotum high, steep; halteres small. Abdomen seven segmented, slender; in the male cylindrical, and with small forceps (PI. 7, Fig. 6); in some forms the seventh segment is reduced and nearly hidden by the sixth sclerite; in the female flattened and ending in a short ovipositor with two small lamellae. Legs moderately strong, all tibia with spurs and lateral sete; fore tibiz with a range of delicate sete on the flexor and another on the extensor surface; there are also several scattered sete; middle tibiz with one range of delicate setee and a single prominent one on the flexor surface, two ranges of rather stout sete on the extensor surface, a single seta between the latter near the apex, and three or four sete in an irregular row near the range on the flexor surface; hind tibize with a range of delicate sete on the flexor surface and two ranges of stout setee on the extensor surface, besides several smaller scattering ones. Wings somewhat longer than the abdomen, elongate oval, with rounded base; subcosta ends in the costa at one-fourth or one-third the wing length from the base and is connected with R, by Sc, (subcostal crossvein) near its apex; the costa ends at the tip of the radial sector and far from the tip of the wing; the basal cell R is very long extending beyond the middle of the wing; the media usually forks noticeably before the base of the radial sector; the cubitus forks proximad of the proximal end of the R-M cross- vein, its anterior branch is sometimes slightly disconnected at the base; the anal vein though rather stout is incomplete (PI. 5, Fig. 12), The larve live in mushrooms. Type species : The name Leva replaces Neoglaphyroptera because Curtis designated L. fascipennis Meigen as the type and because Rondani, the first reviser of the genus, defines it as above. It appears that the name Leja was used by Dejean for a genus of Coleoptera. Scudder dates it 1821 and credits it to Megerle. Lacordaire states that it was used by Dejean in his first catalogue which according to Hagen FAM. MYCETOPHILIDE "7 appeared in 1802. As this catalogue is not accessible to me I am unable to decide the question of syno- nymy; the spelling being different it may be justifiable to use the name Leva even should it be antedated by Lea; if not, it must be replaced by Lejomya, Rondani.

Characters. — A fossil from Alsatia of which the wing is a good condition (PI. 5, Fig. 19). The subcosta (Sc) is very long, nearly reaching the apex of the wing; R, runs parallel to this and ends a little beyond the subcosta; the radial sector, also nearly parallel, ends in the apex of the wing. The R-M crossvein is very oblique; the cubitus forks proximad of the proximal extremity of this crossvein, its branches only slightly divergent; the anal veins incomplete. From the imperfect wing of Adonia fitionia (Platyura), figured by Brodie (Fossil Ins. p. 33 [121], pl. 3, f. 9 [1845}), it appears that the subcosta is very long. Of the posterior part of the wing nothing can be made out. No species are named under Mycetophilites; under Adomia there is only fittonia, Brodie (Platyura fittonia), Fossil Ins. p. 33 (121), pl. 3, f. 9 (1845), from the English Purbecks.

Wings broad, base rounded; costa prolonged far beyond the tip of the radical sector, but not quite reaching the tip of the wing; subcostal vein short and ending in the vein R,; R, ends in the costa beyond the mid-length of the wing; basal section of the radial sector nearly transverse in position, situated at about the middle of the wing; media forks distad of the base of the radial sector; cubitus forks distad of the proximal end of the R-M crossvein which is nearly longitudinal in position and lies in the same line with the last section of the radial sector; anal veins very short, rudi- mentary (PI. 6, Fig. 1). While slight differences exist in the wing venation of Scéarella, Meunier (PI. 6, Fig. 2), and Heeriella, Meunier (Pl. 6, Fig. 3), both fossil forms, they are hardly sufficient to warrant considering them as distinct from Parastemma. In Scarella the base of the petiole of the media (i. e. the second section of the media) is nearer the base of the wing, thus the R-M crossvein is longer, while in Heervella the subcostal vein appears to be longer, and the humeral crossvein and the vein Sc, are equidistant from the base of the wing.

Characters. — Head round, flattened in front, placed low upon the thorax; front broad, the anterior margin produced in a triangle, the apex of which reaches to the base of the antenne; eyes round; ocelli three in number, the laterals large, contiguous to the eye margin, the middle one small, placed in a groove near the base of the frontal triangle; palpi incurved, four jointed, the first joint small, the fourth about as long as the second and third taken together; antenne in the male frequently, in the female usually nearly cylindrical, slender, arcuate, 2 + 14 jointed, the two basal joints differenti- ated, the second with sete at the apex, flagellar joints cylindrical, slightly compressed, pubescent. Thorax oval, highly arched, mesonotum hairy, the hairs on the sides longer, no sete ; scutellum nearly semicircular, margin setose, metanotum high, somewhat arched. Abdomen of the male slender, six segmented, compressed, constricted at the base, with rather large apical segment and forceps (PI. 7, Fig. 12); female with seven segmented abdomen, cylindrical, constricted at the base, with ovipositor ending in two lamella. Legs slender, fore tibia shorter than the corresponding tarsi, all tibia with spurs and lateral setae. Wings oval, with a more or less rounded base, somewhat longer than the abdomen, microscopic setulose. Costa produced, sometimes only very slightly, beyond the tip of the radial sector and ending at a greater or less distance from the tip of the wing; subcosta short, usually ending free, rarely ending in the costa; media forks distad of the base of the radial sector, rarely directly under it; cubitus forks distad of the fork of the media, its branches usually widely divergent; anal veins incom- plete, almost rudimentary (PI. 6, Fig. I 1). The forking of the media distad of the base of the radial sector, and the produced costa will distinguish this genus from Evxechta, The flies are found in woods and among shrubbery usually in Spring and Fall. 96 n> Io.

Characters. — Head oval, flattened in front, placed low upon the thorax; front broad, the anterior margin produced into a triangle which descends to the base of the antennz; eyes oval; ocelli small, two in number, contiguous to the eye margin; antenne projecting forward, 2+ 10, 2-+ 1a, or 2 + 14 jointed, very short, but little longer than the head, the joints shorter than broad, disc-like (Pl. 1, Fig. 7), usuatly closely sessile, pubescent; palpi four jointed, the basal joint very small, the second much enlarged, thickened, compressed, third and fourth slender, almost filiform, placed at an angle with the second, pubescent (PI. |, Fig. 9). Thorax oval, highly arched, sometimes produced over the head; mesonotum with short and depressed hairs, posteriorly with few weak sete; scutellum large, setose on the margin; metanotum somewhat arched. Abdomen compressed, constricted at the base, seven segmented, the seventh usually very small and retracted, in the male with small but complex forceps (PI. 7, Fig. 20), the ovipositor of the female short, stout, with two small lamellae. Legs slender, the tarsi long, the femora compressed, the tibize spurred, the fore and middle pairs rarely with lateral setae, the hind pair with two ranges of very delicate ones on the extensor surface; the plante of the hind tarsi ciliate with microscopic setule. Wings as long or shorter than the abdomen, oval, with rounded base, with microscopic setule arranged in regular longitudinal rows. Costa does not extend beyond the tip of the radial sector and ends some distance from the tip of the wing; subcosta very short, curved toward Rr; media forks distad of the basal section of the radial sector, its posterior branch sometimes not reaching the wing margin; cubitus forks either proximad or distad of the fork of the media; anal veins incomplete (PI. 6, Fig. 13). The larve live in rotten wood and in fungi. The adult insects may be taken at all times except in winter in woods and shrubbery. The description of Brevicornu given by Marshall agrees perfectly as far as it goes with Cordyla, but no mention is made of the stout second palpal joint, though it appears to be indistinctly shown in that author’s figure. 100 3: i: Io.

GENUS RHYMOSIA, WINNERTZ Rhymosia, Winnertz, Verh. Zool.-bot. Ges. Wien, Vol. 13, p. 810 (29) (1863). Characters, — Head oval, vertex somewhat raised, front broad, narrowed anteriorly; eyes nearly circular, somewhat bulging; ocelli three in number, the laterals large, closely contiguous to the eye margin, the middle one very minute, placed in a groove on the front, sometimes almost concealed; palpi incurved, four jointed, first joint very small, the fourth longer than the three preceding ; antenne 2-+14 jointed, basal joints differentiated, setose at the apex, the flagellar joints cylindrical, compressed, pubescent. Thorax oval, highly arched; mesonotum short haired, usually only the margin with sete; scutellum large, margin setose; metanotum high, steep. Abdomen of the male six segmented, with small terminal segment and rather small forceps (PI. 7, Fig. 13), that of the female seven segmented, slender, constricted at the base, compressed, with short, stout ovipositor and a pair of terminal lamelle. Legs long and slender, tibiz with spurs and slender lateral setae. Wings oval, with rounded base, about as long as the abdomen, with microscopic setule arranged in parallel longitudinal rows. Costa ends before the tip of the wing, meeting there the radial sector; subcosta very short, ending either free or in R, ; fork of the media proximad or under the base of the 1adial sector, petiole hence very short; cubitus usually forks, under or proximad of the proximal end of the R-M crossvein, its elongate fork narrow at the base then suddenly divergent; anal vein very stout, rather long, though not reaching the,wing mar- gin; last anal vein long, slender, but incomplete (Pl. 6, Fig. 16). The larvae live in fungi (Avmul- lavia and others). The elongate fork of the cubitus, narrow at the base and then suddenly divergent, will distin- guish this genus from most of the others; the strong though incomplete anal vein will distinguish it from those species of Allodia which have the long forked cubitus.

Characters. — Head round, flattened in front, placed low upon the thorax, front broad; eyes round; ocelli three in number, the laterals large, contiguous to the eye margin, the middle one very small, ina groove; palpi incurved, four jointed, the first small, the fourth longest; antenne 2-++-14 jointed, the basal joints differentiated, the flagellar joints cylindrical, pubescent. Thorax oval, highly arched; mesonotum with depressed hairs, only the margin setose; scutellum large, with marginal sete. Abdomen of the male six segmented, with complex torceps (Pl. 7, Fig. 14, 15), the female abdomen with seven segments, slender, compressed, constricted at the base, with short ovipositor ending in two slender lamella. Legs long and slender, all tibiz with long spurs and minute lateral setee. Wings shorter or not longer than the abdomen, oval, with rounded base, and with microscopic setule arranged in parallel longitudinal rows. Costa ends some distance before the tip of the wing at the point where the radial sector terminates; subcosta very short and either ends free or in R,; media forks under or distad of the base of the radial sector; cubitus forks proximad of the base of the fork of the media, and frequently even 104 proximad of the proximal end of the R-M crossvein; first anal vein delicate, short, incomplete (Allodia, DIPTERA Winnertz) or entirely wanting (Brachycampta, Winnertz), second anal delicate and incomplete. The characters given by Winnertz for distinguishing Allodza from Brachycampta are as follows : In Allodia (Pl. 6, Fig. 18) the first anal vein though short is more or less distinct; in Brachy- campta (Pl. 6, Fig. 17) it is wanting; in the latter the fork of the cubitus is sometimes formed as in Rhymosia, the base of the fork being retracted proximad of the proximal extremity of the R-M crossvein, while in Allodia this is not the case. These characters, while sufficient to separate most of the European species thus far described, fail utterly for some of the North American still undescribed forms, and for this reason, the two genera are combined.

Wales (2), Vol. 3, p. 1215, (14) (1888). Characters. — Head roundish, compressed in the front part, situated deep in the thorax; front broad. Eyes longish round; lateral ocelli large, closely contiguous to the eye margin, middle ocellus either very small, placed in a groove on the front, or entirely wanting (PI. |, Fig. 22); palpi incurved, four jointed, first joint small, fourth longest; antenne projecting forward, somewhat arcuated, 2+14 jointed, first joint of the scapus cyathiform, second much shorter than the first, cupuliform, both setiferous at the tip; flagellar joints cylindrical, somewhat compressed, with minute downy pubescence. Thorax ovate, highly arched, with a short pubescence, setose on the lateral and hind bor- ders; scutellum semicircular, setose, metanotum steep. Abdomen slender, in the male with six, in the female with seven segments, narrowed at the base, cylindrical or a little compressed; anal joint of the male rather large, forceps moderate or small (PI. 7, Fig. 16); ovipositor of the female very short, with two small lamella. Legs long, slender, intermediate and hind femora rather broadly compressed, tibize spurred, and with lateral spines; fore pair with one distinct range of very minute spines on the inner side, and a few small spines along the outer side, intermediate pair with a range of small spines on each side, hind pair with two ranges of rather longer spines on the extensor surface (PI. 1, Fig. 17); plante of metatarsus of hind tarsus with minute setule. Wings shorter, subequal, or a little longer than the abdomen, oblong oval, with rounded base, with microscopic setule arranged in longitudinal rows. Subcostal vein very short, complete or incomplete, directed toward R,; costal vein does not extend beyond the tip of the radial sector and does not reach the tip of the wing ; media forks under or proxi- mad of the basal sector of the radial sector; cubitus forks distad of the fork of the media, its branches widely divergent; anal veins rather long but incomplete (PI. 6, Fig. 19). Brachydicrania and Parexechia do not differ from Exechia except that they possess but two ocelli while Exechia has three, the middle one being very minute. The forms with two ocelli should not be confused with Mycetophila which has very stout tibial lateral seta, and larva with ambulacral setule. The larvee of Exechia are commonly present in many species of fungi. They do not have the transverse rows of ambulacral setule. Type species : EL. fungorum, Degeer.

Ges. Wien, Vol. 13, p. gog (38) (1863). Characters. — Head round, flattened in front, the anterior margin of the thorax produced over it; front broad, its anterior margin produced into a triangle which descends to the base of the antenne; eyes small, round; ocelli small, laterals close to the eyes, the middle one very small, difficult to see, placed in a groove at the base of the frontal triangle; palpi incurved, four jointed, the first joint very small, the fourth longest; antenna nearly cylindrical, slender, somewhat arcuate, 2 + 14 jointed, the basal joints differentiated, the flagellar joints cylindrical, somewhat compressed, pubescent. Thorax oval, arched, anterior margin produced over the head, in profile forming a continuous curve with the head; mesonotum pubescent, the lateral margins over the base of the wings and the posterior margin setose; scutellum semicircular, margin setose; mesonotum not high, steep. somewhat arched. Abdomen short, not slender, laterally compressed, very broad, strongly constricted at the base, in the male six segmented, with small anal segment and small forceps; in the female seven segmented, the seventh IIo DIPTERA segment always retracted, the ovipositor short, with two small lamella. Legs strong, the hind pair long, the fore and middle pairs short; coxee and femora compressed, broad; the tibia somewhat clavate, with strong spurs; fore and middle pairs with one or two small sete on the extensor surface, the middle pair usually with two or three on the flexor surface, the hind pair with two ranges of stout sete on the extensor surface; plante of the hind tarsi ciliate with fine setulae. Wings longer than the abdomen, oval, with somewhat rounded base; surface with longitudinal rows of microscopic setulae. Costa more or less produced beyond the tip of the radial sector, but not reaching the tip of the wing; subcosta incomplete, curved toward but not reaching the costa; media forks under or proximad of the base of the radial sector; cubitus forks under or proximad of the base of the fork of the media, the angle at the base very acute, the branches but slightly diverging; the first anal vein rudimentary or wanting, the second long but incomplete (PI.6, Fig. 20). The flies may be found in woods during the Summer and Fall. The presence of the ocelli, and the usually slightly produced costa will distinguish this genus from Mycetophila; the divergent branches of the cubitus will separate it from Mycotherva. The genera, however, run very closely together. Type species: E. scatophora, Perris. Geographical distribution of species : 1. E. aterrima, Zetterstedt, Dipt. Scand.

Thorax oval, highly arched, produced over the head, pubescent, the lateral margin and over the base of the wing with longer hairs, posterior margin setose; scutellum usually semicircular, its margin setose ; metanotum highly arched. Abdomen of the male six segmented, anal segment usually small, forceps small (Pl. 7, Fig. | 7); that of the female seven segmented, more or less compressed, constricted at the base, ovipositor with two lamella. Legs stout, the femora compressed; tibia with spurs, fore tibiz with small setae on the outer side, middle tibize with two ranges of stout seta on the extensor surface, and one range on the inner side; hind tibie with two or three ranges of long stout sete on the extensor surface; planta of the hind tarsi ciliate with fine setulae. Wings somewhat longer than the abdomen, oval, its base more or less rounded, the microscopic setulae arranged in longitudinal rows. Costa not produced beyond the tip of the radial sector and does not reach the tip of the wing; subcosta very short, incomplete, curved toward but not reaching the costa; media forks under or proximad of the base of the radial sector, its petiole very short; fork of the cubitus proximad, under or sometimes even slightly distad of the fork of the media, its branches usually parallel on the apical half, rarely slightly convergent or divergent; first anal vein incomplete, the second usually stout, and incomplete (PI. 6, Fig. 23, 24, abnormal). The flies of this genus are frequently found in woods and shrubbery wherever fungi grow, at all seasons except in midwinter. The larvae, which live in fungi and in rotten wood, possess transverse rows of microscopic ambulacral setulae upon the margins of the segments of the venter; differing in this respect from the larvee of Phronia, Exechia, Rhymosia, and the like. The parallel branched cubitus, the two ocelli, and the stout tibial lateral setae will separate this genus from its nearest relatives. Type species: WM. agavici, Meigen (1803).
