SOME NEW AND INTERESTING SPECIES OF
SAPROMYZA.
BY CHARLES W. JOHNSON.
Boston Society of Natural History, Boston, Mass. The recent synopsis of the Sapromyzidse by Prof. A. L. Melan- der (PSYCHE, vol. XX, pp. 57-88, 1913), induced me to go over some material that had accumulated for several years. The results were something of a surprise. The series represented by the following species is what one would expect to find if he had only the two extremes, but thefact that practically all of the intermediate species really exist is doubly interesting. Two of the species suggest the remarkable posterior tarsi of Platypeza (Calotarsa), thus presenting an interesting case of parallelism.
It is also interesting to note the wide distribution of some species and the apparently restricted distribution of others. Their similarity in size and color is probably one of the causes why these new species have been overlooked so long, and more careful collecting will undoubtedly show that these are more widely distributed than here indicated.
Sapromyza omatipes sp. nov.
PI. 3, figs. 1, 2, 3.
Male: Face, front and antennre yellow, the front slightly darker than the face, arista black, base yellow, pubescence short. Thorax yellow, slightly pminose, hairs black, with three dorso-centrals, scutellum yellow with four large marginal bristles.
Abdomen dark yellow.
Halteres and legs light yellow, posterior tarsi whitish, metatarsi with a row of short black bristles along the outer side and two long, curved, black subapical bristles slightly broader and flattened at the ends, the two following joints as broad as they are long, black, base white, thickly covered with black hairs and with two long curved bristles on each, similar to those on the metatarsi, the remaining joints brownish at the tips, with small black bristles and hairs. Wings hyaline, clouded with brown, the latter starting near the junction of the second and third veins and extending to a little beyond the anterior cross vein and along the costa from near the end of the first to the end of the fourth vein, with a partial interruption just beyond the end of the second vein, a band also extending across the wing covering the posterior cross vein. Length 3.5 mm. Female similar to the male except that the posterior tarsi are not differentiated, although the second and third joints are black.

19141 . Johnson-Some New and Interesting Species of Sapromyza 21 Six specimens. Holotype and allotype, Mt. Everett, Mass., June 27, and paratypes, Mt. Everett and BashBish Falls, Berk- shire Co., Mass., June 28, 1912 (C. W. Johnson and J. A. Cush- man), in the collection of the Boston Society of Natural History. Sapromyza melanderi sp. nov. PI. 3, figs. 4, 5, 6. Male: Front and antennae bright yellow, the face and occiput light yellow, arista pubescent, black, base yellow. Thorax dark yellow, with three dorso-centrals, scutellum yellow with four marginal bristles. Abdomen dark yellow. Halteres and legs light yellow, posterior tarsi whitish, tip of the metatarsus black and broad- ened, the following joint as broad as it is long, black with the basal third- white, the next joint only slightly broadened apically and these joints are each armed with two longer, curved black bristles as in S. ornatipes, but less flattened at the ends. Wings hyaline with the cloudings less distinct than in the preceding species, the costal clouded area being often obsolete beyond both the anterior cross-vein and the end of the second vein, and the band extending to the posterior cross-vein interrupted. Length, 3 mm.
The female resembles the male except that the posterior tarsi are simple, the tips of the metatarsi and the outer half of the following joints black. Eight specimens. Holotype and allotype, Providence, Mass.. June 24, Paratypes, Eastham, June 27 and, Barnstable, Mass., July 5, 1904 (C. W. Johnson); Nantucket, July 4, 1906 (J. A, Cushman) and Aug. 7 and 15 (H. T. Fernald). Sapromyza cornpedita Loew. PI. 3, figs. 7, 8, 9. A common and widely distributed species. The second joints only of the posterior tarsi black and as broad as they are long. The clouding of the wing is confined to the apical portion above the posterior cross-vein, with only a small clouding at the anterior cross-vein.
Sapromyza houghii Coquillett. PI. 3, figs. 10, 11. The posterior tarsi are similar to those of S. compedita except that the second joints are slightly smaller. The clouding on the wing however is closer to that of of S. rnelanderi. I have collected and received this species from the following localities:-Blue Hills, June 16, Eastham, June 27, Edgartown, June 28 and Horse Neck Beach, Mass., July 30 (C. W. Johnson); Sharon, Mass., Aug. 3 (J. A. Cushman) ; Kingston,. Aug. (John Barlow); West Thompson, Conn., July 12 (H. L. Viereck); Wash-

ington, R. I., June 19, Atco, N. J., June 12 and Suffolk, Va., June 11 (C. W. Johnson).
Sapromyza sheldoni Coquillett.
This has the clouding of the wings very similar to that of S. ornatipes except that both the costal and subcostal cells are clouded. The posterior tarsi are not differentiated. Additional records for this species are Fort Kent, Me., Aug. 19 (C. W. Johnson); Orono, Me., Aug. 13 (C. P. Alexander); Wellesley, Mass., July 11 (E. P. Van Duzee). Sapromy disjuncta sp. nov. PI. 3, figs. 12, 13. Male:
Face, front and antennae yellow, arista black. Thorax dull yellow, slightly pollinose, four dorso-centrals; scutellum yellow. Abdomen yellowish brown, lamellae large, whitish, fringed with long, black hairs. Halteres and legs yellow, tarsi whitish, the second joints of the posterior tarsi black, scarcely enlarged, tips of the remaining joints brownish. Wings hyaline, a clouding at the anterior and posterior cross-veins, at the ends of the second, third and fourth veins, and a spot midway between the anterior cross-vein and the end of the second vein slightly fused with the clouding at the end of the second vein. Female similar to the male. Length 3.5 mm.
Twenty-two specimens. Holotype, Washington, R. I., June 19, and allotype, Buttonwoods, R. I., June 15, 1912. In the
collection of the Boston Society of Natural History. Paratypes,
Bretton Woods, N. H., June 25, Boston, June 6, Cambridge, June 21, Dedham, Sept. 4 and Mt. Tom, Mass., Sept. %, Tiver- ton, R. I., July 31, Darien, Conn., May 27, June 11, Ithaca, N. Y., July 23, Delaware Water Gap, July 12 and Wildwood, N. J., Aug. 12, Philadelphia, June 20 and Frazer, Pa., July 24 (C. W. Johnson) ; Branford, Ct., ( H. L. Viereck) ; Norway, Me. (S. J. Smith); "N. Y. and Ct."(Osten Sacken) Mus. Comp. Zool. A specimen from Jacksonville, Fla., collected by Mrs. A. T. Slosson and referred to S. compedita also belongs to this species. The clouding of the wing is similar to that of S. philadelphica but the black second joint of the posterior tarsi distinguishes it from that species.
Sapromyza conjuncta sp. nov.
Male: Face, front and antennae light yellow, arista blackish, base yellow, pubes- cence very short?.
Thorax dull yellow, slightly pollinose, with four dorso-centrals, scutellum noticeably lighter in color than the thorax. Abdomen reddish brown;

The fact has recently come to the notice of the writer that the name Ancistrocephalus, recently employed by him for a new genus of Mallophaga, is preoccupied, having been used by Monticelli for a genus of Cestode worms in about 1890; this name, therefore, cannot be used for the Mallophagan and is herewith substituted by the name Physconella. The type of this genus is Physconella kelloggi Paine, as described in the paper referred to in the accom- panying footnote.
