A SYNOPSIS OF THE SAPROMYZIDAE.1
BY A. L. MELANDER,
Pullman, Washington.
In the Genera Insectorum, Fascicle 68 (1908), Friedrich Hendel has given an excellent review of the group Lauxaniinse, generally known to American entomologists as the Sapromyzidse. As this work has introduced several changes in nomenclature differing from the list of species as given in Aldrich's Catalogue, and as there has appeard no complete review of the North American species, the following synopsis is offered. It may seem presumptuous to publish this review, based as it is mainly on descriptions, for I have in all but eighty species of the family in my collection for reference, but the value of working tables in assisting future stu- dents is obvious enough to excuse its appearance in print. Naturally, the attempt to visualize a species from a brief de- scription alone does not assure the most satisfactory results; so that the following tables give largely an artificial classification. Such attempts at reconstructing a mind-picture of the species have proved especially unsatisfactory in the big group Lauxania, where the assignment of the species to Minettia or to Sapromyza has some- times been merely a guess.
I am indebted to my colleague and neighbor, Professor J. M. Aldrich, for the inspiration that prompted this review and for his material assistance in sharing his library and collection during its progress. His collection has extended the distribution of many species, and in the following pages the localities of his species are added with the designation "Aldrich." Those localities marked with the asterisk (*) are represented in my collection. The North American species of Sapromyza have been twice tabulated. In 1892 Mr. C. H. Tyler Townsend published a "Preliminary Grouping of Sapromyza " in the Canadian Entomolo- gist, pages 301 to 304. The next year appeared "El Ghero Sapro- 1 Contribution from the Zoological Laboratory of the State College of Washington. Pu&e 2057-83 (1913). hup Ytpsychu einclub orgt2WM-057.htd

58 Psyche [April
myza en America" by Felix Lynch Arribalzaga, in the Anales de la Sociedad Cientifica Argentina, xxxiv., pages 253 to 301. The subgenus Sapromyza is our dominant group. The species
may sometimes be difficult to place correctly in a tabulation since their yellow color may change at death. Where confusion was most obvious the species have been several times included in the key. Spottings of the abdominal segments may become vague through a darkening of the general color. Again, there is some variation in the extent of color markings; as, for example, univittata, areola, and tinnula, probably varieties of a single species, show gradations in the extent of the mesonotal stripe, etc. Flavipennis Fabricius, with bare arista, is not the same species as flavipennis described by Wiedemann, although Wiedemann 's specimens came from Fabricius' collection. .
The following description of a new genus of Sciomyzidae is in- cluded in this paper, since it deals with a species hitherto classed as a Saprornyza.
PCECILOMYIA: A NEW GENUS OF SCIOMYZID~. (Figs. 1 and 2.) In a note in connection with the original description of Sapromyza decora, Loew stated that the shape of the head and particularly of the antennae was very much like that of certain Tetanoceras, in view of which the species should be separated from Sapromyza as a distinct genus. Not recalling this note when studying speci- mens of decora I came independently to the same conclusion, and coincidentally received a letter from Mr. C. W. Johnson conveying the same suggestion.
Decora is an unusually distinct species, with its reticulate wings and maculate body. It clearly is not a Sapromyzine because of the following array of characters. These characters are invariably, or at least usually, associated with the Tetanocerine Sciomyzidse and are not at all, or at most very rarely. found in the Sapromyzidse. Front broadly convex, the periorbits separated from the unusually broad, shin- ing, central part by a strong suture; face strongly concave, the oral margin project- ing, but the clypeus (Chitinhufeisen) rudimentary; cheeks nearly as deep as the eye-height; postvertical bristles divergent; second antenna1 joint elongate and bristly; the third joint triangular, pointed, excised above; palpi long and linear; thorax with a fine scabrous coating; prothoracic, inesopleural, and sterno-pleural bristles all wanting; front femora without a series of bristles on posterior flexor edge; middle tibiae without preapical spur but with apical crown of bristles; wings with complete anal vein.




================================================================================

19131 Melander-A Synopsis of the Supromyzidae 59 The species is therefore certainly to be excluded from the Sapro- myzidse, and as there is no genus in the Sciomyzidse to receive it, I would propose for it the new generic name Poedlomyia. A further characterization presents the following: Head in profile a little higher than broad, the upper portion spherical; perior- bits less than one-fourth the width of the interfrontalia (Mittelleiste), separated from it by well-marked sutures which are parallel with the eye-margin on the front, but converge at the vertex to meet the sutures of the epicephalon (cerebrale) of the occiput. The interfrontalia is uniformly convex, glabrous, and highly polished, is darker than the silky periorbits, and is marked with a translucent median stripe extending forward from the anterior ocellus. The arms of the frontal suture (Stirn- spalteniiste) continue weakly to the lower edge of the eye, but at the usual antenna1 dark spot they send a suture across to the eye thus dividing the frontal from the facial orbits (Wangendreieck). The lunula is completely covered. The face (Gesichtsleiste) narrow but widening below, at its middle no wider than the sides (Wangen), in profile considerably concave, with oral margin projecting. Clypeus (Schlundgeriist) entirely undeveloped. Palpi linear, porrect, extending beyond oral margin, hairy beneath. Cheeks (Backen) one-half the eye-height, hairy, rounding into the sides of the face (ohne Vibrisseneck). Paracephala (Hinter- hauptsorbiten) loosely setose; a closely setulose patch above the neck. Eyes rounded, but obliquely longer than wide. First joint of antennae small, nearly bare, immersed in its socket; second joint conical, with the upper inner side pro- jecting most, the outer side about one-half the length of the third joint, the inner side subequal to this joint, setose, except the outside, and with three long bristles on the upper edge; third joint pointed, somewhat excised above, uniformly fine- hairy; the dark arista rather loosely and evenly plumose above and below; the whole antenna no longer than eye-breadth, with the arista shorter than the last two joints. The bristles of the head are long and strong and include: a pair of diverging post- verticals, a convergent inner and a divergent outer vertical, % reclinate fronto- orbitals and a stout pair of proclinate ocellar bristles. The lesser ocellars are very small.
The orbital bristles arise from dark-colored papillae. The chaetotaxy of
the thorax is as follows: 1 humeral, 0 posthumeral, 2 notopleurar, 1 presutural, 3 dorsocentral, 1 pair prescutellar, 2 pair convergent scutellar, 1 supraalar, and 2 approximate postalar bristles; no prothoracic or pleural bristles, except a couple (Vallarborsten) on the pteropleural ridge just under the calypter. Meso-, ptero-, and sternopleurse with scattered fine hairs, the last with a bristle in the angle below. Calypteres pale yellow, with pale fringe. Front femora with several bristles in extensor row, hind femora 3 biseriately spinose beneath; front and hind tibiae with preapical bristle, middle tibiae with usual ending of bristles. Last two segments of abdomen with long submarginal bristles; hypopygium globose. Wings reticulate with alternating light and dark spots, costal margin unbroken; first vein ending midway between tip of auxiliary vein and the anterior cross vein; veins not sinuate, third and fourth veins subparallel; anal vein conlplete. Type : Sapromyza decora Loew.
Of the eighteen genera cf Sciomyzidse before me the new genus



================================================================================

60 Psyche [April
bears most resemblance to Trypetoptera Hendel, but presents these differences: first vein ending far before the anterior cross vein; meso- and pteropleurse with very fine hairs which are scarcely bristle-like; second antennal joint obconical and not rounded; calypteres pale; fronto-orbital sutures distinct, in Trypetoptera the periorbits are not differentiated; three dorsocentral bristles. None of the other genera, except Coremacera Rondani, have the periorbits so definitely separated from the interfrontalia. The
presence of three dorsocentrals and of a convex and broad middle portion of the front are unusual characters in the Sciomyzidse. Table of Genera.
