383A New Species of Sapromyzidae from the Hawaiian Islands(Diptera).BY J. R. MALLOCH.(Presented by E. H. Bryan, Jr., at the meetingDecember 2, 1926)The species described below is the only one which I haveseen from the Hawaiian Islands and is probably the saitne whichwas recorded without a specific name by Grimshaw in the"Fauna Hawaiiensis."Homcneura hawaiiensis n. sp.Male and female.—Head testaceous, greyish dusted, interfrontalia withtwo dark vittae, face with a dark transverse mark below the antennaeinsertions, and another near lower margin; antennae and palpi testaceous.Thorax largely or entirely fuscous and densely grey dusted; margin ofscutellum always testaceous. Abdomen testaceous, some or all of thetergites with a fuscous fascia which leaves a variable amount of apex andbase of each pale, fifth tergite in male and fifth and sixth in female with apair of small black spots. Legs dull testaceous. Wings clear, cross veinsslightly darker than other veins. Halteres pale yellow.Frons about 1.5 as long as wide, with short surface hairs, the orbitsslightly differentiated, all bristles except the ocellars strong and long, theocellars not half as long as anterior orbitals; arista pubescent; f^ce slightlybulging over the impressed mouth margin; lower occipital bristles strong.Thorax with three pairs of strong dorsocentrals, the anterior pa|ir close tosuture, one pair of strong prescutellar acrostichals, six series of intradorsocentral hairs, and two sternopleurals. Hypopgium stout, the tergite forming its base with apical processes stout and truncate, projecting jlownward.Fore femur with an anteroventral comb; all tibiae with a distinct preapicaldorsal bristle; hind femur with one or two preapical anteroventral bristles.Inner cross vein at middle of discal cell; penultimate section of fourth veintwo-thirds as long as ultimate.Length, 4-4.5 mm.Type and allotype, on same mount, type male, Tantalus,Oahu (O. H. Swezey). Paratypes.: two, same localityj as type,and same collector; two, Honaunau, Hawaii (J. G. j Stokes);two, Puna, Hawaii, (O. H. Swezey) ; one, Wailupk Oahu,(O. H. Swezey) ; one, Waiahole, Oahu, (E. H. Bryan, Jr.) ;one, Palehua, Oahu, (O. H. Swezey) ; one, Waimalu, OahuProc. Haw. Ent. Soc, VI, No. 3, Oct., 1927.384(J. C. Bridwell) ; one, Kilohana, Kauai, (O. H. Swezey) ; one,Keanae, Maui, (E. H. Bryan, Jr.); one, Kapaa, Kauai, (J. A.Kusche) ; one, Kauai, (W. H. Ashmead). The last specimenis in the United States National Museum. The others weresent to me by E. H. Bryan, Jr., of the Bernice P. BishopMuseum, to whom they will be returned except two specimensretained by the writer.The genus Homoneura was described by van der Wulp forthe reception of a species from Sumatra and it is the same concept as Sapromyzosoma Malloch. In the genus there are overa hundred Oriental species known to me, and it contains somewell defined segregates which I have just assigned subgenericnames in a paper ready for the press. The Hawaiian speciesbelongs to a group which I have retained in Homoneura in thestrict sense, though the arista is only pubescent and the fronsis longer and narrower than in the typical form.
